IntroductionTrough blood levels (C0) of tacrolimus are used to adjust drug dosage, but they do not consistently correlate with clinical outcomes. Measurement of residual gene expression of nuclear factor of activated T cell (NFAT)-regulated genes (NFAT-RGE) has been proposed as a pharmacodynamic biomarker to assess the degree of immunosuppression in certain solid organ transplantations, but little is known regarding lung transplant recipients (LTR). Our primary objective is to correlate tacrolimus blood levels with NFAT-RGE.MethodsNFAT-RGE and tacrolimus C0 and peak (C1.5) levels were determined in 42 patients at three, six and 12 months post-transplantation.ResultsTacrolimus C0 did not exhibit a correlation with NFAT-RGE, whereas C1.5 did. Besides, over 20% of measurements indicated high levels of immunosuppression based on the below 30% NFAT-RGE threshold observed in many studies. Among those measurements within the therapeutic range, 19% had an NFAT-RGE

Abstract Background The use of remote consultation modalities has exponentially grown in the past few years, particularly since the onset of the COVID-19 pandemic. Although a huge body of the literature has described the use of phone (tele) and video consultations, very few of the studies correspond to randomized controlled trials, and none of them has assessed the safety of these consultation modalities as the primary objective. The primary objective of this trial was to assess the safety of remote consultations (both video and teleconsultation) in the follow-up of patients in the hospital setting. Methods Multicenter, randomized controlled trial being conducted in four centers of an administrative healthcare area in Catalonia (North-East Spain). Participants will be screened from all individuals, irrespective of age and sex, who require follow-up in outpatient consultations of any of the departments involved in the study. Eligibility criteria have been established based on the local guidelines for screening patients for remote consultation. Participants will be randomly allocated into one of the two study arms: conventional face-to-face consultation (control) and remote consultation, either teleconsultation or video consultation (intervention). Routine follow-up visits will be scheduled at a frequency determined by the physician based on the diagnostic and therapy of the baseline disease (the one triggering enrollment). The primary outcome will be the number of adverse reactions and complications related to the baseline disease. Secondary outcomes will include non-scheduled visits and hospitalizations, as well as usability features of remote consultations. All data will either be recorded in an electronic clinical report form or retrieved from local electronic health records. Based on the complications and adverse reaction rates reported in the literature, we established a target sample size of 1068 participants per arm. Recruitment started in May 2022 and is expected to end in May 2024. Discussion The scarcity of precedents on the assessment of remote consultation modalities using randomized controlled designs challenges making design decisions, including recruitment, selection criteria, and outcome definition, which are discussed in the manuscript. Trial registration NCT05094180. The items of the WHO checklist for trial registration are available in Additional file 1. Registered on 24 November 2021.

Abstract Aim The main aim of the present study is to examine the expectations and feelings of people awaiting lung transplantation. Background The assessment of the benefits of lung transplant should consider, among other things, the subjective perceptions of patients about the procedure, especially in relation to the context and to their values, goals and expectations. This is an issue that has not been studied in depth, especially in Spain. Design Exploratory qualitative study. Methods Data were collected through semi‐structured interviews during the period of being on the waiting list for transplantation. Thematic analysis of the data was supported by the Atlas.ti software. Results The study population comprised 16 patients awaiting lung transplant, a number sufficient to reach data saturation. Four categories were identified to describe patients' feelings and expectations: (1) reasons for undergoing the transplant, (2) expectations about life post‐transplant, (3) emotional state, and (4) relationship with the healthcare team. Conclusions Patients have high expectations of lung transplantation. They see it as offering them a second chance at life, although the future creates uncertainty. The healthcare professionals are identified as key actors, providing essential support and information throughout the various stages of the process. Future research should explore recipients' experiences of lung transplant at later stages. Relevance to clinical practice It is important to adapt care through all the lung transplant process, which is accompanied by intense and complex emotions since the beginning. Thus, providing social and psychological support from the beginning may contribute to their health status, helping them deal with all the emotions and feelings experienced, and find balance between expectations and reality. Patient or public contribution Sixteen patients awaiting lung transplant were interviewed. Interview transcripts were returned to participants to check for accuracy with their experiences.

Background: Strong and broad antiviral T-cell responses targeting vulnerable sites of HIV-1 will likely be a critical component for any effective cure strategy. Methods: BCN01 trial was a phase I, open-label, non-randomized, multicenter study in HIV-1-positive individuals diagnosed and treated during early HIV-1 infection to evaluate two vaccination regimen arms, which differed in the time (8 versus 24 week) between the ChAdV63.HIVconsv prime and MVA.HIVconsv boost vaccinations. The primary outcome was safety. Secondary endpoints included frequencies of vaccine-induced IFN-γ+ CD8+ T cells, in vitro virus-inhibitory capacity, plasma HIV-1 RNA and total CD4+ T-cells associated HIV-1 DNA. (NCT01712425). Findings: No differences in safety, peak magnitude or durability of vaccine-induced responses were observed between long and short interval vaccination arms. Grade 1/2 local and systemic post-vaccination events occurred in 22/24 individuals and resolved within 3 days. Weak responses to conserved HIV-1 regions were detected in 50% of the individuals before cART initiation, representing median of less than 10% of their total HIV-1-specific T cells. All participants significantly elevated these subdominant T-cell responses, which after MVA.HIVconsv peaked at median (range) of 938 (73-6,805) IFN-γ SFU/106 PBMC, representing on average 58% of their total anti-HIV-1 T cells. The decay in the size of the HIV-1 reservoir was consistent with the first year of early cART initiation in both arms. Interpretation: Heterologous prime-boost vaccination with ChAdV63-MVA/HIVconsv was well-tolerated and refocused pre-cART T-cell responses towards more protective epitopes, in which immune escape is frequently associated with reduced HIV-1 replicative fitness and which are common to most global HIV-1 variants. Funding: HIVACAT Catalan research program for an HIV vaccine and Fundació Gloria Soler. Vaccine manufacture was jointly funded by the Medical Research Council (MRC) UK and the UK Department for International Development (DFID) under the MRC/DFID Concordat agreements (G0701669. Research in Context: Evidence Before this Study: T cells play an important role in the control of HIV infection and may be particularly useful for HIV-1 cure by killing cells with reactivated HIV-1. Evidence is emerging that not all T-cell responses are protective and mainly only those targeting conserved regions of HIV-1 proteins are effective, but typically immunologically subdominant, while those recognizing hypervariable, easy-to-escape immunodominant ‘decoys’ do not control viremia and do not protect from a loss of CD4 T cells. We pioneered a vaccine strategy focusing T-cell responses on the most conserved regions of the HIV-1 proteome using an immunogen designated HIVconsv. T cells elicited by the HIVconsv vaccines in HIV-uninfected UK and Kenyan adults inhibited in vitro replication of HIV-1 isolates from 4 major global clades A, B, C and D.Added Value of this Study: The present study demonstrated the concept that epitopes subdominant in natural infection, when taken out of the context of the whole HIV-1 proteome and presented to the immune system by a potent simian adenovirus prime-poxvirus MVA boost regimen, can induce strong responses in patients on antiretroviral treatment and efficiently refocus HIV-1-specific T-cells to the protective epitopes delivered by the vaccine.Implications of all the Available Evidence: Nearly all HIV-1 vaccine strategies currently emphasize induction of broadly neutralizing Abs. The HIVconsv vaccine is one of a very few approaches focussing exclusively on elicitation of T cells and, therefore, can complement antibody induction for better prevention and cure. Given the cross-clade reach on the HIVconsv immunogen design, if efficient, the HIVconsv vaccines could be deployed globally. Effective vaccines will likely be a necessary component in combination with other available preventive measures for halting the HIV-1/AIDS epidemic

Romidepsin (RMD) is a well-characterized histone deacetylase inhibitor approved for the treatment of cutaneous T-cell lymphoma. in vitro and in vivo studies have demonstrated that it is able to induce HIV-1 gene expression in latently infected CD4+ T cells from HIV-1+ individuals on suppressive antiretroviral therapy. However, in vitro experiments suggested that RMD could also impair T-cell functionality, particularly of activated T cells. Thus, the usefulness of RMD in HIV-1 kick&kill strategies, that aim to enhance the immune system elimination of infected cells after inducing HIV-1 viral reactivation, may be limited. In order to address whether the in vitro observations are replicated in vivo, we determined the effects of RMD on the total and HIV-1-specific T-cell populations in longitudinal samples from the BCN02 kick&kill clinical trial (NCT02616874). BCN02 was a proof-of-concept study in 15 early treated HIV-1+ individuals that combined MVA.HIVconsv vaccination with three weekly infusions of RMD given as a latency reversing agent. Our results show that RMD induced a transient increase in the frequency of apoptotic T cells and an enhanced activation of vaccine-induced T cells. Although RMD reduced the number of vaccine-elicited T cells secreting multiple cytokines, viral suppressive capacity of CD8+ T cells was preserved over the RMD treatment. These observations have important implications for the design of effective kick&kill strategies for the HIV-1 cure.

El Museu de Sabadell fue inaugurado el mes de agosto de 1931; sus orígenes, sin embargo, se remontan a 1912, cuando Joan Vila Cinca realizó las primeras excavaciones arqueológicas en la ciudad, concretamente junto al santuario de la Salut, donde localizó una villa romana. Este mismo año el Ayuntamiento creó la Junta de Museus i Excavacions, con el objetivo de continuar las excavaciones y crear un Museo. A partir de aquí, se desplegó una importante una actividad arqueológica que aún no ha cesado y que ha permitido que en la actualidad el Museo disponga de unas importantes colecciones arqueológicas, representativas del pasado de la ciudad y sus alrededores, que en muchos casos son un referente en el conocimiento de la prehistoria europea, como son la Bòbila Madurell o la necrópolis de campos de urnas del Bronce final y Primera Edad del Hierro de Can Piteu.

Breast cancer (BC) is one of the most important neoplasias among women. Many patients receive radiotherapy (RT), which involves radiation exposure of the thoracic zone, including the heart and blood vessels, leading to the development of cardiovascular disease (CVD) as a long-term side effect. The severity of CVD-related pathologies leads research on assessing novel CVD biomarkers as diagnostic, prognostic or therapeutic agents. Currently, the possible candidates include blood microRNAs (miRNAs). Previous studies have supported a role for miRNA-146a, -155, -221, and -222 in the progression of CVD. Our purpose was to evaluate the RT-induced modulation of the expression of these miRNAs in the blood of women with BC. Pre-RT control and post-RT blood samples were collected, and after miRNA isolation and reverse transcription, the levels of the selected miRNAs were measured by real-time PCR. Our results showed that miRNA-155 exhibited the lowest expression, while miRNA-222 exhibited the highest expression, followed by miRNA-221. The expression of each individual miRNA was positively correlated with that of the others both pre-RT control and post-RT and inversely correlated with age before RT. Furthermore, RT promoted the overexpression of the selected miRNAs. Their levels were also affected by CVD-linked clinical parameters, treatment and BC side. Modulation of the expression of the selected miRNAs together with other risk factors might be associated with the development of future cardiovascular pathologies. Further confirmatory studies are needed to assess their potential as possible biomarkers in the progression of or as therapeutic targets for RT-induced CVD in BC patients.

Since 1998, a monitoring program is periodically performed to assess the environmental and human health impact of air chemicals potentially emitted by a hazardous waste incinerator (HWI) located in Constantí (Catalonia, Spain). In 2017, samples of hair were collected from 94 schoolchildren (aged 10−13 years) living nearby and the levels of 11 trace elements (As, Be, Cd, Cr, Hg, Mn, Ni, Pb, Sn, Tl and V) were determined. The concentrations showed the following descending order: Pb > Hg > Ni > Sn > Mn > Cr. In turn, As, Be and Tl were not detected, while Cd and V were found only in a few samples. Some metal levels were significantly, positively correlated. Some significant differences were also noticed according to the gender and the specific zone of residence. Finally, the levels of trace elements showed fluctuations through time. Cr and Pb showed a significant decrease in comparison to the concentrations obtained in the baseline study (1998). According to the current results, metal emissions from the HWI are not relevant in terms of human health impact since their levels were similar and even lower than those reported in other contaminated areas.

Compulsive buying behavior (CBB) has begun to be recognized as a condition worthy of attention by clinicians and researchers. Studies on the commonalities between CBB and other behavioral addictions such as gambling disorder (GD) exist in the literature, but additional research is needed to assess the frequency and clinical relevance of the comorbidity of CBB and GD. The aim of the study was to estimate the point-prevalence of CBB+GD in a clinical setting. Data corresponded to n=3,221 treatment-seeking patients who met criteria for CBB or GD at a public hospital unit specialized in treating behavioral addictions. Three groups were compared: only-CBB (n=127), only-GD (n=3,118) and comorbid CBB+GD (n=24). Prevalence for the co-occurrence of CBB+GD was 0.75%. In the stratum of patients with GD, GD+CBB comorbidity obtained relatively low point prevalence (0.77%), while in the subsample of CBB patients the estimated prevalence of comorbid GD was relatively high (18.9%). CBB+GD comorbidity was characterized by lower prevalence of single patients, higher risk of other behavioral addictions (sex, gaming or internet), older age and age of onset. CBB+GD registered a higher proportion of women compared to only-GD (37.5% vs. 10.0%) but a higher proportion of men compared to only-CBB (62.5% vs. 24.4%). Compared to only-GD patients, the simultaneous presence of CBB+GD was associated with increased psychopathology and dysfunctional levels of harm avoidance. This study provides empirical evidence to better understand CBB, GD and their co-occurrence. Future research should help delineate the processes through which people acquire and develop this comorbidity.

Aims: The primary objective of this study was to analyze the association between alcohol consumption and short-term response to treatment (post intervention) in male patients with gambling disorder enrolled in a group cognitive behavioral therapy (CBT) program.Methods: The sample consisted of 111 male individuals with a diagnosis of Gambling Disorder, with a mean age of 45 years (SD= 12.2). All participants were evaluated by a comprehensive assessment battery and assigned to CBT groups of 10-14 patients attending 16 weekly outpatient sessions lasting 90 min each.Results: The highest mean pre- and post-therapy differences were recorded for the alcohol risk/dependence group on the obsessive/compulsive and anxiety dimensions of the SCL-90-R. As regards the presence of relapses and dropouts over the course of the CBT sessions, the results show a significant association with moderate effect size: patients with risk consumption or alcohol dependence were more likely to present poor treatment outcomes.Conclusions: Alcohol abuse was frequent in GD, especially in patients with low family income and high accumulated debts. High levels of somatization and high overall psychopathology (measured by the SCL-90-R) were associated with increased risk of alcohol abuse. Alcohol abuse was also associated with poor response to treatment.

Objectives: The present study aimed to investigate if eating disorder patients differ in specific personality traits depending on a positive screening of food addiction and to find a model to predict food addiction in eating disorder patients using measures of personality and impulsivity. Methods: 278 patients having an eating disorder self-reported on food addiction, impulsivity, personality, eating and general psychopathology. Patients were then split into two groups, depending on a positive or negative result on the food addiction screening. Analysis of variance was used to compare means between the two groups. Stepwise binary logistic regression was used to obtain a predictive model for the presence of food addiction. Results: Patients with food addiction had lower self-directedness, and more negative urgency and lack of perseverance than patients not reporting addictive eating. The probability of food addiction can be predicted by high negative urgency, high reward dependence, and low lack of premeditation. Conclusions: Eating disorder patients who have more problems to pursue tasks to the end and to focus on long-term goals seem to be more likely to develop addictive eating patterns.

Molecular fingerprinting of conserved germline and somatic ¨stemness¨ markers in different taxa have been key in defining the mechanism of germline specification (preformation or epigenesis), as well as expression domains of somatic progenitors. The distribution of molecular markers for primordial germ cells (PGCs), including vasa, nanos and piwil1, as well as Vasa antibody staining, support a determinative mechanism of germline specification in the cephalochordate Branchiostoma lanceolatum, similarly to other amphioxus species. pl10 and bruno2, but not bruno4/6, are also expressed in a pattern consistent with these other germline genes, adding to our repertoire of PGC markers in lancelets. Expression of nanos, vasa and the remaining markers (musashi, pufA, pufB, pumilio and piwil2) may define populations of putative somatic progenitors in the tailbud, the amphioxus posterior growth zone, or zones of proliferative activity. Finally, we also identify a novel expression domain for musashi, a classic neural stem cell marker, during notochord development in amphioxus. These results are discussed in the context of germline determination in other taxa, stem cell regulation and regenerative capacity in adult amphioxus.

Though it is accepted that emerging infectious diseases are a threat to planet biodiversity, little information exists about their role as drivers of species extinction. Populations are also affected by natural catastrophes and other pathogens, making it difficult to estimate the particular impact of emerging diseases. Border disease virus genogroup 4 (BDV-4) caused a previously unreported decrease in populations of Pyrenean chamois (Rupicapra p. pyrenaica) in Spain. Using a population viability analysis, we compared probabilities of extinction of a virtual chamois population affected by winter conditions, density dependence, keratoconjunctivitis, sarcoptic mange and BDV outbreaks. BDV-affected populations showed double risk of becoming extinct in 50 years, confirming the exceptional ability of this virus to drive chamois populations.

Background: Gambling disorder (GD) is characterized by a significant lack of self-control and is associated with impulsivity-related personality traits. It is also linked to deficits in emotional regulation and frequently co-occurs with anxiety and depression symptoms. There is also evidence that emotional dysregulation may play a mediatory role between GD and psychopathological symptomatology. Few studies have reported the outcomes of psychological interventions that specifically address these underlying processes. Objectives: To assess the utility of the Playmancer platform, a serious video game, as an additional therapy tool in a CBT intervention for GD, and to estimate pre-post changes in measures of impulsivity, anger expression and psychopathological symptomatology. Method: The sample comprised a single group of 16 male treatment-seeking individuals with severe GD diagnosis. Therapy intervention consisted of 16 group weekly CBT sessions and, concurrently, 10 additional weekly sessions of a serious video game. Pre-post treatment scores on South Oaks Gambling Screen (SOGS), Barratt Impulsiveness Scale (BIS-11), I7 Impulsiveness Questionnaire (I7), State-Trait Anger Expression Inventory 2 (STAXI-2), Symptom Checklist-Revised (SCL-90-R), State-Trait Anxiety Inventory (STAI-S-T), and Novelty Seeking from the Temperament and Character Inventory-Revised (TCI-R) were compared. Results: After the intervention, significant changes were observed in several measures of impulsivity, anger expression and other psychopathological symptoms. Dropout and relapse rates during treatment were similar to those described in the literature for CBT. Conclusion: Complementing CBT interventions for GD with a specific therapy approach like a serious video game might be helpful in addressing certain underlying factors which are usually difficult to change, including impulsivity and anger expression.

Objectives. To investigate the mediating mechanisms of oppositional defiant disorder (ODD) in preschoolers through pathways analysis, considering the family socioeconomic status (SES) as the independent variable and the parenting style and the children’s executive functioning (EF) as the mediating factors.Method. Sample included 622 three years-old children from the general population. Multi-informant reports from parents and teachers were analyzed.Results. Structural Equation Modeling showed that children’s gender achieved a moderating role into the pathways valuing the underlying process between SES, EF, parenting style and ODD levels: a) for girls, the association of low SES and high ODD scores was mediated by parenting practices (punishment and inconsistent discipline) and by difficulties in EF inhibition, and a direct predictive effect on ODD level was achieved for SES, punishment and inconsistence in rearing style and inhibition; b) for boys, SES and EF (inhibition and emotional control) had a direct effect on ODD with no mediation.Conclusion. SES seems a good indicator to identify at high-risk children for prevention and intervention programs for ODD. Girls with ODD in families of low SES may particularly benefit from parent training practices and training in inhibition control.

Objective: The aims of the study were to 1) validate the Difficulties in Emotion Regulation Scale (DERS) in a sample of Spanish adults with and without eating disorders, and 2) explore the role of emotion regulation difficulties in eating disorders, including its mediating role in the relation between key personality traits and ED severity Methods: 134 patients (121 female, mean age = 29 years) with anorexia nervosa (n = 30), bulimia nervosa (n = 54), binge eating (n = 20), or Other Specified Feeding or Eating Disorders (n = 30) and 74 healthy control participants (51 female, mean age = 21 years) reported on general psychopathology, eating disorder severity, personality traits and difficulties in emotion regulation. Exploratory and confirmatory factor analyses were conducted to examine the psychometrics of the DERS in this Spanish sample (Aim 1). Additionally, to examine the role of emotion regulation difficulties in eating disorders (Aim 2), differences in emotion regulation difficulties across eating disorder subgroups were examined and structural equation modeling was used to explore the interrelations among emotion regulation, personality traits, and eating disorder severity. Results: Results support the validity and reliability of the DERS within this Spanish adult sample and suggest that this measure has a similar factor structure in this sample as in the original sample. Moreover, emotion regulation difficulties were found to differ as a function of eating disorder subtype and to mediate the relation between two specific personality traits (i.e., high harm avoidance and low self-directedness) and eating disorder severity. Conclusions: Personality traits of high harm avoidance and low self-directedness may increase vulnerability to eating disorder pathology indirectly, through emotion regulation difficulties.

Neural correlates of working memory (WM) in healthy subjects have been extensively investigated using functional MRI (fMRI). However it still remains unclear how cortical areas forming part of functional WM networks are also connected by white matter fiber bundles, and whether DTI measures, used as indices of microstructural properties and directionality of these connections, can predict individual differences in task performance. FMRI data were obtained from 23 healthy young subjects while performing one visuospatial (square location) and one visuoperceptual (face identification) 2-back task. Diffusion tensor imaging (DTI) data were also acquired. We used independent component analysis (ICA) of fMRI data to identify the main functional networks involved in WM tasks. Voxel-wise DTI analyses were performed to find correlations between structural white matter and task performance measures, and probabilistic tracking of DTI data was used to identify the white matter bundles connecting the nodes of the functional networks. We found that functional recruitment of the fusiform and the inferior frontal cortex was specific for the visuoperceptual working memory task, while there was a high overlap in brain activity maps in parietal and middle frontal areas for both tasks. Axial diffusivity and fractional anisotropy, of the tracts connecting the fusiform with the inferior frontal areas correlated with processing speed in the visuoperceptual working memory task.Although our findings need to be considered as exploratory, we conclude that both tasks share a highly-overlapping pattern of activity in areas of frontal and parietal lobes with the only differences in activation between tasks located in the fusiform and inferior frontal regions for the visuoperceptual task. Moreover, we have found that the DTI measures are predictive of the processing speed.

Background.The lifetime prevalence of problem or Gambling disorder (GD) in the elderly (i.e., those over 60 years old) is reported to range from 0.01% to 10.9%. Research has identified several specific risk factors and vulnerabilities in the elderly. Since the late 1990s, an increase in online GD has been observed in the youth population, whereas casinos, slot machines, and bingo seem to be the activities of choice among the elderly. Interestingly, online GD has not been described in the elderly to date.Case Description.We report an 83-year-old man who started online casino gambling from the age of 80 years, leading to debts that exceeded €30,000. He underwent a full clinical and neuropsychological assessment, without any evidence of cognitive impairment or any associated neurodegenerative disease. However, he had risk factors for GD, including adjustment disorder, stressful life events, previous offline casino GD when 50 years old, and dysfunctional personality traits. The change to online GD may have been due to his isolation, movement difficulties, and his high level of education, which facilitated his access to the Internet. Care management focused on individual cognitive-behavioral therapy.Conclusion.The prevalence of online GD may be underestimated among the elderly, and may increase among isolated old people with movement difficulties and ready access to the Internet. However, late-life GD should be considered a diagnosis of elimination, requiring a full medical, psychiatric (including suicide risk), and cognitive assessment. Specific therapeutic approaches need to be proposed and developed.

Healthy aging (HA) is associated with certain declines in cognitive functions, even in individuals that are free of any process of degenerative illness. Functional magnetic resonance imaging (fMRI) has been widely used in order to link this age-related cognitive decline with patterns of altered brain function. A consistent finding in the fMRI literature is that healthy old adults present higher activity levels in some brain regions during the performance of cognitive tasks. This finding is usually interpreted as a compensatory mechanism. More recent approaches have focused on the study of functional connectivity, mainly derived from resting state fMRI, and have concluded that the higher levels of activity coexist with disrupted connectivity. In this review, we aim to provide a state-of-the-art description of the usefulness and the interpretations of functional brain connectivity in the context of HA. We first give a background that includes some basic aspects and methodological issues regarding functional connectivity. We summarize the main findings and the cognitive models that have been derived from task-activity studies, and we then review the findings provided by resting state functional connectivity in HA. Finally, we suggest some future directions in this field of research. A common finding of the studies included is that older subjects present reduced functional connectivity compared to young adults. This reduced connectivity affects the main brain networks and explains age-related cognitive alterations. Remarkably, the default mode network appears as a highly compromised system in HA. Overall, the scenario given by both activity and connectivity studies also suggests that the trajectory of changes during task may differ from those observed during resting-state. We propose that the use of complex modeling approaches studying effective connectivity may help to understand context-dependent functional reorganizations in the aging process.

Cell death can occur through different mechanisms, defined by their nature and physiological implications. Correct assessment of cell death is crucial for cancer therapy success. Sarcomas are a large and diverse group of neoplasias from mesenchymal origin. Among cell death types, apoptosis is by far the most studied in sarcomas. Albeit very promising in other fields, regulated necrosis and other cell death circumstances (as so-called ‘autophagic cell death’ or ‘mitotic catastrophe’) have not been yet properly addressed in sarcomas. Cell death is usually quantified in sarcomas by unspecific assays and in most cases the precise sequence of events remains poorly characterized. In this review our main objective is to put into context the most recent sarcoma cell death findings in the more general landscape of different cell death modalities.

Ageing entails cognitive and motor decline as well as brain changes such as loss of grey and white matter integrity, neurovascular and functional connectivity alterations. Regarding connectivity, reduced resting-state fMRI connectivity between anterior and posterior nodes of the Default Mode network (DMN) relates to cognitive function and has been postulated to be a hallmark of ageing. However, the relationship between age-related connectivity changes and other neuroimaging-based measures in ageing is fragmentarily investigated. In a sample of 116 healthy elders we aimed to study the relationship between antero-posterior DMN connectivity and measures of white matter integrity, grey matter integrity and cerebral blood flow, assessed with an arterial spin labeling sequence. First, we replicated previous findings demonstrating DMN connectivity decreases in ageing and an association between antero-posterior DMN connectivity and memory scores. The results showed that the functional connectivity between posterior midline structures and the medial prefrontal cortex was related to measures of white matter and grey matter integrity but not to cerebral blood flow. Grey and white matter correlates of anterio-posterior DMN connectivity included, but were not limited to, DMN areas and cingulum bundle. These results resembled patterns of age-related vulnerability which was studied by comparing the correlates of antero-posterior DMN with age-effect maps. These age-effect maps were obtained after performing an independent analysis with a second sample including both young and old subjects. We argue that antero-posterior connectivity might be a sensitive measure of brain ageing over the brain. By using a comprehensive approach, the results provide valuable knowledge that may shed further light on DMN connectivity dysfunctions in ageing.

Early life stress (ELS) in rodents has profound long-term effects that are partially mediated by changes in maternal care. ELS not only induces detrimental effects in adulthood, increasing psychopathology, but also promotes resilience to further stressors. In Long-Evans rats, we evaluated a combination of two procedures as a model of ELS: restriction of bedding during the first postnatal days and exposure to a substitute mother. The maternal care of biological and substitute mothers was measured. The male and female offspring were evaluated during adulthood in several contexts. Anxiety was measured by the elevated plus-maze (EPM), acoustic startle response (ASR) and forced swim test (FST). In other group of animals, novelty-seeking was measured (activity in an inescapable novel environment, preference for novel environments and exploration of novel objects). Plasmatic ACTH and corticosterone in basal conditions and in response to stress were also measured. Cognitive impulsivity was assessed by a delay-discounting paradigm, and impulsive action, attention and compulsive-like behaviour by a five choice serial reaction time task (5CSRTT). ELS decreased pup body weight and increased the care of the biological mother; however, the substitute mother did not exhibit overt maltreatment. A mixture of detrimental and beneficial effects was shown. In the 5CSRTT, attention was impaired in both genders, and in females, ELS increased compulsive-like behaviour. Novel object exploration was only increased by ELS in males, but the preference for novel spaces decreased in both genders. Baseline anxiety (EPM and ASR) and recognition memory were not affected. Unexpectedly, ELS decreased the ACTH response to novelty and swim stress and increased active coping in the FST in both genders. Cognitive impulsivity was decreased only in females, but impulsive action was not affected. The enhancement in maternal care may buffer the effects of ELS in a context-dependent manner.

The effect of maraviroc on the maintenance and the function of HIV-1-specific T cell responses remains unknown.Subjects recently infected with HIV-1 were randomized to receive anti-retroviral treatment with or without maraviroc intensification for 48 weeks, and were monitored up to week 60. PBMC and in vitro-expanded T cells were tested for responses to the entire HIV proteome by ELISpot analyses. Intracellular cytokine staining assays were conducted to monitor the (poly)-functionality of HIV-1-specific T cells. Analyses were performed at baseline and week 24 after treatment start, and at week 60 (3 months after maraviroc discontinuation).Maraviroc intensification was associated with a slower decay of virus-specific T cell responses over time compared to the non-intensified regimen in both direct ex-vivo as well as in in-vitro expanded cells. The effector function profiles of virus-specific CD8⁺ T cells were indistinguishable between the two arms and did not change over time between the groups.Maraviroc did not negatively impact any of the measured parameters, but was rather associated with a prolonged maintenance of HIV-1-specific T cell responses. Maraviroc, in addition to its original effect as viral entry inhibitor, may provide an additional benefit on the maintenance of virus-specific T cells which may be especially important for future viral eradication strategies.

Despite the development of valuable new techniques (i.e. genetics, neuroimage) for the study of the neurobiological substrate of psychiatric diseases, there are strong limitations in the information that can be gathered from human studies. It is thus critical to develop appropriate animal models of psychiatric diseases to characterize their putative biological bases and the development of new therapeutic strategies. The present review tries to offer a general perspective and several examples of how individual differences in animals can contribute to explain differential susceptibility to develop behavioural alterations, but also emphasizes methodological problems that can lead to inappropriate or over-simplistic interpretations. A critical analysis of the approaches currently used could contribute to obtain more reliable data and allow taking full advantage of new and sophisticated technologies. The discussion is mainly focused on anxiety-like and to a lower extent on depression-like behaviour in rodents.

Exposure of animals to footshocks (FS) in absence of any specific cue results in the development of fear to the compartment where shocks were given (contextual fear conditioning), and this is usually evaluated by time spent freezing. However, the extent to which contextual fear conditioning always develops when animals are exposed to other stressors is not known. In the present work we firstly demonstrated, using freezing, that exposure of adult rats to a single session of FS resulted in short-term and long-term contextual fear conditioning (freezing) that was paralleled by increased hypothalamic-pituitary-adrenal (HPA) activation. In contrast, using a similar design, no HPA or behavioural evidence for such conditioning was found after exposure to immobilization on boards (IMO), despite this stressor being of similar severity as FS on the basis of standard physiological measures of stress, including HPA activation. In a final experiment we directly compared the exposure to the two stressors in the same type of context and tested for the development of conditioning to the context and to a specific cue for IMO (the board). We observed the expected high levels of freezing and the conditioned HPA activation after FS, but not after IMO, regardless of the presence of the board during testing. Therefore, it can be concluded that development of fear conditioning to context or particular cues, as evaluated by either behavioural or endocrine measures, appears to be dependent on the nature of the aversive stimuli, likely to be related to biologically preparedness to establish specific associations.

In recent years, several theories have been proposed in attempts to identify the neural mechanisms underlying successful cognitive aging. Old subjects show increased neural activity during the performance of tasks, mainly in prefrontal areas, which is interpreted as a compensatory mechanism linked to functional brain efficiency. Moreover, resting-state studies have concluded that elders show disconnection or disruption of large-scale functional networks. We used functional MRI during resting-state and a verbal n-back task with different levels of memory load in a cohort of young and old healthy adults to identify patterns of networks associated with working memory and brain default mode. We found that the disruption of resting-state networks in the elderly coexists with task-related overactivations of certain brain areas and with reorganizations within these functional networks. Moreover, elders who were able to activate additional areas and to recruit a more bilateral frontal pattern within the task-related network achieved successful performance on the task. We concluded that the balanced and plastic reorganization of brain networks underlies successful cognitive aging. This observation allows the integration of several theories that have been proposed to date regarding the aging brain.

Antiphospholipid syndrome (APS) is known as a rare etiology of embolic ischemic stroke. In individuals below 50 years, up to 20% of strokes are associated with APS, whereas in patients >50 years, it is considered a very seldom cause of stroke. We describe the course of a 66-year-old white woman, who experienced four embolic strokes with large vessel occlusion over a period of 2 years, which were repeatedly and successfully treated by mechanical thrombectomy. Initially attributed to atrial fibrillation and treated with direct oral anticoagulants, the patient was finally diagnosed with primary APS due to isolated anti-beta 2-glycoprotein antibodies and successfully treated after several stroke recurrences. After initiation of Vitamin K antagonist therapy, no further strokes occurred. For recurrent embolic stroke despite oral anticoagulation, late-onset APS might be considered a rare etiology also in the elderly., Competing Interests: There are no conflicts of interest., (Copyright: © 2024 Brain Circulation.)

Background: Delivering bad news to patients is one of the most challenging tasks in medical practice. Despite its great relevance to patients, relatives, and medical staff, there is a paucity of data pertaining to training, experience, expectations, and preferences of physicians and medical students on breaking bad news., Methods: We conducted an international survey in Germany, Switzerland, and Austria using an online questionnaire among physicians and medical students., Results: A total of 786 physicians and 303 medical students completed the survey. Physicians stated that 32.7% deliver bad news several times a week and 45.2% several times a month. Difficulties controlling their emotions (35.1%) and remaining professional (43.4%) were the greatest challenges for physicians. Delivering bad news is associated with feelings of anxiety, both among experienced physicians (median of 3.8 out of 10.0) and medical students (median of 5.3). Conveying bad news is a burden to physicians and consequently has a substantial impact on their job satisfaction. All participants reported the need for more communication training concerning this subject. Only 49.5% of medical students and 67.3% of physicians mentioned having learned adequate communication skills. Our data demonstrate that communication training decreases the level of anxiety and increases the feeling of self-confidence towards breaking bad news. Preferred educational tools were seminars with simulation (students: 71.4%, physicians: 49.5%), observing more senior faculty (students: 57.4%, physicians: 55.1%), and supervision and feedback sessions (students: 36.3%, physicians: 45.7%). The largest barriers regarding education on communication were limited time (students: 77.0%, physicians: 74.9%) and missing awareness of supervisors (students: 60.6%, physicians: 41.1%)., Conclusions: Our study showed a great need for systematic training and education in breaking bad news among physicians and medical students. Hospitals, medical schools, and postgraduate training programs are strongly encouraged to fill this gap, and improve sustainable doctor-patient communication to overcome the psychological burden for physicians., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2023.

Background: Malignant sex cord-stromal cell tumours (SCST) account for only 7% of ovarian malignancies. The Arbeitsgemeinschaft fuer Gynaekologische Onkologie (AGO) study group has established a clinicopathological database to provide an overview of the current treatment strategies and survival of SCST patients and to identify research needs., Methods: Twenty centres provided mixed retro- and prospective data of patients with tumour specimens and second-opinion pathology review treated between 2000 and 2014. Descriptive analyses of treatment strategies, Kaplan-Meier curves and cox regression analyses were conducted., Results: Two hundred and sixty-two SCST patients were included. One hundred and ninety-one Granulosa-cell tumour (GCT) and 17 Sertoli-Leydig cell tumour (SLCT) patients were stage I disease (>80%). Forty four GCT (18.7%) and two (8.3%) SLCT patients received adjuvant systemic treatment. After a median observation time of 78.2 months, 46% of all SCST patients experienced disease recurrence, treated predominantly with secondary debulking surgery (> 90%). Advanced FIGO stage, lymph node involvement and intra-operative capsule rupture were associated with disease recurrence on univariate analysis (all p < 0.05). Median OS time was not reached., Discussion: In this analysis of SCST patients, adjuvant chemotherapy was unable to prevent disease recurrence. Despite high recurrence rates, overall survival rates were excellent., (© 2023 The Authors. Journal of Surgical Oncology published by Wiley Periodicals LLC.)

Objective: Adult granulosa cell tumors represent less than 5% of all ovarian malignancies. The aim of this study was to analyze the clinicopathological parameters and their impact on progression-free and overall survival., Methods: Patients with primary adult granulosa cell tumors treated in three international referral centers between July 1999 and December 2018 were included. The following data were anonymously exported from the prospective database: age at diagnosis, International Federation of Gynecology and Obstetrics (FIGO) stage, adjuvant therapy, surgical procedures, progression-free survival, and overall survival. Descriptive statistical analysis regarding tumor and treatment characteristics was performed. Survival analyses included Kaplan-Meier functions and Cox proportional hazard ratios (HR)., Results: A total of 168 patients with primary adult granulosa cell tumors were included. Median age was 50 years (range 13-82). With regard to stage distribution, 54.2% (n=91) of patients were FIGO stage IA, 1.2% (n=2) were stage IB, 26.8% (n=45) were stage IC, and 17.9% (n=30) were FIGO stage II-IV. 66.7% (n=112) of patients underwent surgical restaging, of whom 17.9% (n=20) were moved to a higher stage. In addition, 36 (21.4%) patients underwent fertility-sparing surgery. After a median follow-up of 61 months (range 0-209), 10.7% of patients (n=18) had recurrent disease and 4.8% (n=8) died of disease. Five-year progression-free survival was 86.1% and estimated overall survival was 95.7%. Five-year progression-free survival was worse for patients with advanced stages (FIGO stage IA/B vs IC: HR 5.09 (95% CI 1.53 to 16.9); FIGO stage IA/B vs II-IV: HR 5.62 (95% CI 1.58 to 19.9)). Nineteen patients receiving adjuvant chemotherapy had lower estimated 5-year progression-free survival compared with patients not receiving chemotherapy (49.7% vs 91.1%, p<0.001; HR 9.15 (95% CI 3.62 to 23.1))., Conclusion: The prognosis of patients with primary adult granulosa cell tumors is mainly determined by FIGO stage. The outcome of patients with FIGO stage IC is comparable to those with advanced stages. Fertility-sparing surgery seems to be a safe procedure in stage IA. Our data do not support the use of adjuvant chemotherapy in early and advanced stages of adult granulosa cell tumors., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2023.

Background/aim: Lynch syndrome (LS) is the secondary cause of hereditary ovarian cancer (OC). Germline mutations in the DNA-mismatch repair (MMR) genes cause tumorigenesis and a high immunogenicity. Recent studies showed a promising use of immunotherapy in MMR deficient (MMRd) tumors. This is a case report of a patient with LS-associated OC and a complete response to pembrolizumab., Case Report: A 44-year-old patient was admitted to the hospital with lower abdominal pain. The patient's history showed LS with a germline mutation in the MSH2-gene. Initial diagnostics showed a pelvic tumor mass and a highly elevated cancer antigen 125. After debulking surgery, histopathological findings showed a high-grade serous OC with mutations in the MSH2 and MSH6 genes. Only 5 weeks after operation with no residual tumor mass, a quick and significant intraabdominal progression of the disease was diagnosed. Adjuvant therapy with carboplatin and paclitaxel in a weekly course did not lead to sustainable response. An anti-PD-L1 antibody therapy with pembrolizumab was initiated. After only two courses of therapy, the laboratory results and clinical status of the patient improved tremendously. Shortly after, a complete response was detected, and therapy is still ongoing. The patient remains tumor free for 21 months now., Conclusion: The significance of germline compared to somatic mutations has not yet been sufficiently investigated. To our knowledge, this is the first case with complete response to checkpoint inhibition in OC associated with LS. Regarding LS-associated OC, immune checkpoint inhibition is an efficient therapy in tumors nonresponsive to standard therapy., (Copyright © 2023 International Institute of Anticancer Research (Dr. George J.

Objective: Gynecological sarcomas account for 3% of all gynecological malignancies and are associated with a poor prognosis. Due to the rarity and heterogeneity of gynecological sarcomas there is still no consensus on optimal therapeutic strategies. This study's objective was to describe the treatment strategies used in patients with gynecological sarcomas in the primary course of disease., Methods: The German prospective registry for gynecological sarcoma (REGSA) is the largest registry for gynecological sarcomas in Germany, Austria and Switzerland. Primary inclusion criteria for REGSA are histological diagnosis of sarcoma of the female genital tract, sarcoma of the breast or uterine smooth muscle tumors of uncertain malignant potential (STUMP). We evaluated data of the REGSA registry on therapeutic strategies used for primary treatment from August 2015 to February 2021., Results: A total of 723 patients from 120 centers were included. Data on therapeutic strategies for primary treatment were available in 605 cases. Overall, 580 (95.9%) patients underwent primary surgery, 472 (81.4%) of whom underwent only hysterectomy. Morcellation was reported in 11.4% (n=54) of all hysterectomies. A total of 42.8% (n=202) had no further surgical interventions, whereas an additional salpingo-ophorectomy was performed in 54% (n=255) of patients. An additional lymphadenectomy was performed in 12.7% (n=60), an omentectomy in 9.5% (n=45) and intestinal resection in 6.1% (n=29) of all patients. Among 448 patients with available information, 21.4% (n=96) received chemo- or targeted therapies, more commonly as single-agent treatment than as drug combinations. Information about anti-hormonal treatment was available for 423 patients, among which 42 (9.9%) received anti-hormonal treatment, 23 (54.8%) of whom with low-grade endometrial stroma sarcomas. For radiotherapy, data of 437 patients were available, among which 29 (6.6%) patients underwent radiotherapy., Conclusion: Our study showed that treatment of patients with gynecologic sarcomas is heterogeneous. Further trials are needed along with more information on treatment modalities, therapy response and patient-reported outcomes to implement new treatment strategies., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2023.

Objectives: Benign leiomyomas are the most common uterine tumors. In contrast, uterine leiomyosarcomas are malignancies with a poor prognosis due to difficulties in early diagnosis and inappropriate surgical treatment. Most often they are diagnosed incidentally after surgery performed for treatment of leiomyoma. As the appropriate surgical treatment is crucial for survival of the patient, there is a high demand to predict leiomyosarcoma pre-operatively. Available scoring systems to discriminate leiomyoma from leiomyosarcoma are based on retrospective studies with limited numbers of patients and are not implemented in routine clinical practice., Methods: The aim of our study was to evaluate a recently published score-the pre-operative leiomyosarcoma (pLMS) score-to determine whether it would have been predictive of leiomyosarcoma in 177 patients from the NOGGO-REGSA study, a German register of histologically proven gynecological sarcoma detected during routine clinical investigation., Results: The threshold of the pLMS score for 'leiomyosarcoma not probable' (< -3) failed for 7.5% of the patients and the threshold 'indicator for leiomyosarcoma' (>+1) was true for 39.1% of the patients. 53.4% of the patients were attributed to the group 'additional investigations are recommended' (-3 to +1). The most relevant parameters in our analysis were suspicious sonography and rapid growth, but neither have been quantitatively defined., Conclusion: In our validation cohort, the pLMS score seems not to be a reliable tool to predict leiomyosarcoma and therefore we do not recommend its clinical implementation to identify leiomyosarcoma., Competing Interests: Competing interests: None declared., (© IGCS and ESGO 2022.

Purpose: Heritable factors play an important etiologic role in connective tissue disorders (CTD) with vascular involvement, and a genetic diagnosis is getting increasingly important for gene-tailored, personalized patient management., Methods: We analyzed 32 disease-associated genes by using targeted next-generation sequencing and exome sequencing in a clinically relevant cohort of 199 individuals. We classified and refined sequence variants according to their likelihood for pathogenicity., Results: We identified 1 pathogenic variant (PV; in FBN1 or SMAD3) in 15 patients (7.5%) and ≥1 likely pathogenic variant (LPV; in COL3A1, FBN1, FBN2, LOX, MYH11, SMAD3, TGFBR1, or TGFBR2) in 19 individuals (9.6%), together resulting in 17.1% diagnostic yield. Thirteen PV/LPV were novel. Of PV/LPV-negative patients 47 (23.6%) showed ≥1 variant of uncertain significance (VUS). Twenty-five patients had concomitant variants. In-depth evaluation of reported/calculated variant classes resulted in reclassification of 19.8% of variants., Conclusion: Variant classification and refinement are essential for shaping mutational spectra of disease genes, thereby improving clinical sensitivity. Obligate stringent multigene analysis is a powerful tool for identifying genetic causes of clinically related CTDs. Nonetheless, the relatively high rate of PV/LPV/VUS-negative patients underscores the existence of yet unknown disease loci and/or oligogenic/polygenic inheritance.

Background: Medications from Anthroposophical Medicine (AM) are clinically used for the treatment of infections within a whole medical system but have not yet been evaluated regarding antibacterial effects. The aims of this study was to investigate antibacterial activity of AM medications in cell culture., Methods: Screening of AM drug registers for preparations used to treat any kind of infection and being available in dilutions ≤ D2 and without alcoholic content. Selected medications were screened for antimicrobial activity against Bacillus subtilis, Escherichia coli, Staphylococcus aureus and Pseudomonas aeruginosa using the agar diffusion method. For antimicrobial active preparations growth kinetics (drop plate method) and minimal inhibitory concentrations (MIC, macrodilution method) were determined., Results: Thirty-three preparations matched the selection criteria and were chosen for own experiments. One of them (Berberis Decoctum D2) exhibited bactericidal activities against Bacillus subtilis and Staphylococcus aureus, including methicillin resistant strains. The MIC could be determined as 5 mg/ml. The effects could be related to the content of berberine in the extract. No activity towards gram-negative bacteria was found. The other tested extracts had no antibacterial effects., Conclusion: Berberis Decoctum D2 which is used in AM to treat infections exhibits bactericidal effects on Staphylococcus aureus, including methicillin resistant strains.
