ABSTRACT

INTRODUCTION: Patients' decisions on prostate cancer (PCa) opportunistic screening may vary. This study aimed to assess how demographic and health-related characteristics may influence knowledge and decisions regarding PCa screening. METHODS: A cross-sectional survey was conducted among men aged over 40, randomly sampled from the Spanish population, 2022. The survey underwent development and content validation using a modified Delphi method and was administered via telephone. Binomial logistic regression was used to explore the relationship between respondents' characteristics and participants' knowledge and practices concerning PCa and the PSA test. RESULTS: Out of 1,334 men, 1,067 (80%) respondents were interviewed with a mean age of 58.6 years (sd 11.9). Most had secondary or university studies (787, 73.8%) and 61 (5.7%) self-reported their health status as bad or very bad. Most of the respondents (1,018, 95.4%) had knowledge regarding PCa with nearly 70% expressed significant concern about its potential development (720, 70.8%), particularly among those under 64 years (p = 0.001). Out of 847 respondents, 573 (67.7%) reported that they have knowledge regarding the PSA test: 374 (65.4%) reported receiving information from a clinicians, 324 (86.6%) information about the benefits of the test and 189 (49,5%) about its risks, with differences based on educational background. In a multivariable analysis (adjusted for age, educational level and previous prostate problems), respondents with higher levels of education were more likely to have higher knowledge regarding the PSA test (OR 1.75, 95%CI 1.24-2.50, p<0.001). CONCLUSIONS: Although most of the patients reported to have knowledge regarding PCa, half of the interviewed men reported knowledge about PSA test. Differences in knowledge prostate cancer screening and undesirable consequences highlight the need to develop and provide tailored information for patients.

ABSTRACT

OBJECTIVE: Understanding the long-term impact of Coronavirus Disease 2019 (COVID-19) on cognitive function, even in mild cases, is critical to the well-being of individuals, especially for healthcare workers who are at increased risk of exposure to the virus. To the best of our knowledge, the electrophysiological activity underlying cognitive functioning has not yet been explored. METHODS: Seventy-seven healthcare workers took part in the study (43 with mild infection about one year before the study and 34 uninfected). To assess cognitive status, event-related potentials (ERPs) and behavioural responses were recorded while participants performed a working memory task. RESULTS: COVID-19 participants exhibited a distinct neural pattern with lower parieto-occipital N1 amplitudes and higher frontal P2 amplitudes as compared to non-infected healthcare workers. We found no behavioural differences (reaction times and error rates) in working memory functioning between groups. CONCLUSIONS: This neural pattern suggests the presence of a decrement of processing resources linked to the encoding of sensory information (N1), followed by the enhanced of the P2 response which could be interpreted as the activation of compensation mechanism in COVID-19 participants. SIGNIFICANCE: The current findings point out that ERPs could serve as valuable neural indices for detecting distinctive patterns in working memory functioning of COVID-19 participants, even in mild cases. However, further research is required to precisely ascertain the long-term cognitive effects of COVID-19 beyond one-year post-infection.

ABSTRACT

There is a growing interest in the potential benefits of attentional bias modification (ABM) training in chronic pain patients. However, studies examining the effectiveness of ABM programs in fibromyalgia patients have demonstrated inconclusive effects on both behavioral indices and clinical symptoms. Additionally, underlying neural dynamics of ABM effects could yield new insights but remain yet unexplored. Current study, therefore, aims to investigate the effects of ABM training on known neural electrophysiological indicators of attentional bias to pain (P2, N2a). Thirty-two fibromyalgia patients were enrolled and randomly assigned to an ABM training (N = 16) or control (N = 16) condition (2 weeks duration). Within the ABM training condition participants performed five sessions consisting of a modified version of the dot-probe task in which patients were trained to avoid facial pain expressions, whereas in the control group participants performed five sessions consisting of a standard version of the dot-probe task. Potential ABM training effects were evaluated by comparing a single pre- and post-treatment session, in which event-related potentials (ERPs) were recorded in response to both facial expressions and target stimuli. Furthermore, patients filled out a series of self-report questionnaires assessing anxiety, depression, pain-related worrying, fear of pain, fatigue and pain status. After training, results indicated an overall reduction of the amplitude of the P2 component followed by an enhancement of N2a amplitude for the ABM condition compared to control condition. In addition, scores on anxiety and depression decreased in patients assigned to the training condition. However, we found no effects derived from the training on pain-related and fatigue status. Present study offers new insights related to the possible neural mechanisms underlying the effect of ABM training in fibromyalgia. Clinical trial (TRN: NCT05905159) retrospectively registered (30/05/2023).

ABSTRACT

Migraine has been considered a chronic neuronal-based pain disorder characterized by the presence of cortical hyperexcitability. The Contingent Negative Variation (CNV) is the most explored electrophysiological index in migraine. However, the findings show inconsistencies regarding its functional significance. To address this, we conducted a review in both adults and children with migraine without aura to gain a deeper understanding of it and to derive clinical implications. The literature search was conducted in the PubMed, SCOPUS and PsycINFO databases until September 2022m and 34 articles were retrieved and considered relevant for further analysis. The main results in adults showed higher CNV amplitudes (with no habituation) in migraine patients. Electrophysiological abnormalities, particularly focused on the early CNV subcomponent (eCNV), were especially prominent a few days before the onset of a migraine attack, normalizing during and after the attack. We also explored various modulatory factors, including pharmacological treatments-CNV amplitude was lower after the intake of drugs targeting neural hyperexcitability-and other factors such as psychological, hormonal or genetic/familial influences on CNV. Although similar patterns were found in children, the evidence is particularly scarce and less consistent, likely due to the brain's maturation process during childhood. As the first review exploring the relationship between CNV and migraine, this study supports the role of the CNV as a potential neural marker for migraine pathophysiology and the prediction of pain attacks. The importance of further exploring the relationship between this neurophysiological index and childhood migraine is critical for identifying potential therapeutic targets for managing migraine symptoms during its development.

ABSTRACT

Introducción: La función para estimar el riesgo cardiovascular de por vida en España –IBERLIFERISK– en población laboral obtuvo una discriminación satisfactoria; se registró una ligera sobreestimación del riesgo en hombres y una infraestimación del riesgo en mujeres. Objetivo: Recalibrar la ecuación de riesgo de por vida actual tras alargar 3 años el seguimiento. Métodos: Estudio de cohortes retrospectivo. Se incluyeron 762.058 trabajadores que realizaron un examen de salud laboral entre los años 2004 y 2007. Se evaluaron todos los episodios de incapacidad temporal y mortalidad cardiovascular hasta diciembre de 2017. Se combinaron los modelos de regresión para tener en cuenta la presencia de riesgos competitivos en la estimación del riesgo cardiovascular en una cohorte de derivación. La calibración se realizó representando gráficamente la proporción de eventos esperados y observados a los 10 años de seguimiento en la cohorte de validación estratificando por deciles de riesgo y calculando el estadístico Z de Spiegelhalter. La discriminación se evaluó de forma gráfica mediante la curva Receiver Operating Curve (ROC) y calculando el índice C de Harrell. Resultados: La media de edad fue de 35,48 años (DE 10,56). El 71,14% eran hombres. El índice C de Harrell fue de 0,78 (IC 95% 0,76-0,79) en hombres y de 0,73 (IC 95% 0,69-0,77) en mujeres. En general, se registró un ligero grado de infraestimación en mujeres y de sobreestimación en hombres en el último decil de riesgo, aunque el estadístico Z de Spiegelhalter no resultó estadísticamente significativo en ambos sexos (p>0,05). Conclusiones: El modelo actualizado continúa discriminando satisfactoriamente, aunque la calibración del modelo no ha mejorado sustancialmente con la nueva actualización.(AU)


Introduction: The function to estimate lifetime cardiovascular risk –IBERLIFERISK– in Spanish working population, obtained a satisfactory discrimination; however, there was a slight overestimation of the risk in men and an underestimation of the risk in women. Objective: To recalibrate the current lifetime risk equation after extending the follow-up by 3 years. Methods: Retrospective cohort study. 762.058 workers who underwent an occupational health examination between 2004 and 2007 were included. All episodes of temporary sickness and cardiovascular mortality up to December 2017 were evaluated. Regression models were combined to take into account the presence of competing risks in estimating cardiovascular risk in the derivation cohort. Calibration was performed by graphically representing the proportion of expected and observed events at 10 years of follow-up in the validation cohort, stratifying by risk deciles and calculating the Spiegelhalter Z statistic. Discrimination was evaluated graphically using the Receiver Operating Curve (ROC) and calculating Harrell's C index. Results: The mean age was 35.48 years (SD 10.56). 71.14% were men. Harrell's C index was 0.78 (95% CI 0.76-0.79) in men and 0.73 (95% CI 0.69-0.77) in women. In general, there was a slight degree of underestimation in women and overestimation in men in the last decile of risk, although the Spiegelhalter Z statistic was not statistically significant in both sexes (p>0.05). Conclusions: The updated model continues to discriminate satisfactorily, although the model's calibration has not substantially improved with the new update.(AU)

ABSTRACT

La presente investigación consistió en un estudio de caso único de un niño de 10 años, procedente de adopción internacional, con síntomas compatibles con trastorno del espectro alcohólico fetal (TEAF). Debido a la complejidad sintomatológica del trastorno y de su diagnóstico, en la actualidad no existen tratamientos contrastados. El estudio comenzó con una evaluación neurocognitiva donde se observaron alteraciones en atención, memoria y funciones ejecutivas, que se manifestaron en una gran impulsividad, así como en dificultades para la autorregulación. Se diseñó un programa de neurorreha- bilitación, de 96 sesiones, centrado en el abordaje multidisciplinar de los aspectos cognitivos, conductuales y funcionales alterados. La aplicación del programa de rehabilitación produjo mejora general en la capacidad funcional del paciente, destacando los procesos de atención y en la capacidad de autorregulación. Los resultados obtenidos ponen en valor la aplicación de programas de neurorrehabilitación multidisciplinares al revelarse como una herramienta eficaz en el tratamiento de la sintomatología clínica del TEAF y la mejora en la adaptación de los pacientes a las exigencias de su vida diaria. (AU)


The present investigation consisted of a single case study of a 10-year-old child from international adoption with symptoms of Fetal Alcohol Spectrum Disorder (FASD). Due to the symptomatological complexity of the disorder and its diagnosis, currently there are no effective treatments. The study started with a neurocognitive evaluation where alterations in attention, memory and executive functions were observed, which manifested themselves in great impulsivity, as well as in difficulties in self-regulation. A 96-ses- sion neurorehabilitation program was designed, focusing on a multidisciplinary approach to the altered cognitive, behavioral and functional aspects. The application of the rehabilitation program produced a general improvement in the patient's functional capacity, specially in attention processes and the capacity for self-regulation. The results obtained highlight the value of the application of multidisciplinary neurorehabilitation programs as an effective tool in the treatment of the clinical symptoms of FASD and the improvement in the adaptation of patients to the demands of their daily lives.

ABSTRACT

A large number of publications have focused on the study of pain expressions. Despite the growing knowledge, the availability of pain-related face databases is still very scarce compared with other emotional facial expressions. The Pain E-Motion Faces Database (PEMF) is a new open-access database currently consisting of 272 micro-clips of 68 different identities. Each model displays one neutral expression and three pain-related facial expressions: posed, spontaneous-algometer and spontaneous-CO2 laser. Normative ratings of pain intensity, valence and arousal were provided by students of three different European universities. Six independent coders carried out a coding process on the facial stimuli based on the Facial Action Coding System (FACS), in which ratings of intensity of pain, valence and arousal were computed for each type of facial expression. Gender and age effects of models across each type of micro-clip were also analysed. Additionally, participants' ability to discriminate the veracity of pain-related facial expressions (i.e., spontaneous vs posed) was explored. Finally, a series of ANOVAs were carried out to test the presence of other basic emotions and common facial action unit (AU) patterns. The main results revealed that posed facial expressions received higher ratings of pain intensity, more negative valence and higher arousal compared with spontaneous pain-related and neutral faces. No differential effects of model gender were found. Participants were unable to accurately discriminate whether a given pain-related face represented spontaneous or posed pain. PEMF thus constitutes a large open-source and reliable set of dynamic pain expressions useful for designing experimental studies focused on pain processes.

ABSTRACT

Recent findings have associated different COMT genotypes with working memory capacity in patients with fibromyalgia. Although it is thought that the COMT gene may influence neural correlates (P2 and P3 ERP components) underlying working memory impairment in this chronic-pain syndrome, it has not yet been explored. Therefore, the aim of the present research was to investigate the potential effect of the COMT gene in fibromyalgia patients on ERP working memory indices (P2 and P3 components). For this purpose, 102 participants (51 patients and 51 healthy control participants) took part in the experiment. Event-related potentials and behavioral responses were recorded while participants performed a spatial n-back task. Participants had to decide if the stimulus coincided or not in the same location as the one presented one (1-back condition) or two (2-back condition) trials before. Genotypes of the COMT gene were determined through a saliva sample from all participants. Present results significantly showed lower working memory performance (p < 0.05) in patients with fibromyalgia as compared to control participants (higher rate of errors and slower reaction times). At neural level, we found that patients exhibited enhanced frontocentral and parieto-occipital P2 amplitudes compared to control participants (p < 0.05). Interestingly, we also observed that only fibromyalgia patients carrying the Val/Val genotype of the COMT gene showed higher frontocentral P2 amplitudes than control participants (p < 0.05). Current results (behavioral outcomes and P2 amplitudes) confirmed the presence of an alteration in working memory functioning in fibromyalgia. The enhancement of frontocentral P2 could be reflecting that these patients would manifest an inefficient way of activating executive attention processes, in carriers of the Val/Val genotype of COMT. To our knowledge, the present findings are the first linking neural indices of working memory dysfunctions and COMT genotypes in fibromyalgia. Applying a subgroup of patient's strategy based on this genetic marker could be useful to establish more tailored therapeutical approaches.

ABSTRACT

Fibromyalgia is a chronic pain syndrome characterized by dysfunctional processing of nociceptive stimulation. Neuroimaging studies have pointed out that pain-related network functioning seems to be altered in these patients. It is thought that this clinical symptomatology may be maintained or even strengthened because of an enhanced expectancy for painful stimuli or its forthcoming appearance. However, neural electrophysiological correlates associated with such attentional mechanisms have been scarcely explored. In the current study, expectancy processes of upcoming laser stimulation (painful and non-painful) and its further processing were explored by event-related potentials (ERPs). Nineteen fibromyalgia patients and twenty healthy control volunteers took part in the experiment. Behavioral measures (reaction times and subjective pain perception) were also collected. We manipulated the pain/no pain expectancy through an S1-S2 paradigm (cue-target). S1 (image: triangle or square) predicted the S2 appearance (laser stimulation: warmth or pinprick sensation). Laser stimuli were delivered using a CO2 laser device. Temporal and spatial principal component analyses were employed to define and quantify the ERP component reliability. Statistical analyses revealed the existence of an abnormal pattern of pain expectancy in patients with fibromyalgia. Specifically, our results showed attenuated amplitudes at posterior lCNV component in anticipation of painful stimulation that was not found in healthy participants. In contrast, although larger P2 amplitudes to painful compared to innocuous events were shown, patients did not show any amplitude change in this laser-evoked response as a function of pain predictive cues (as occurred in the healthy control group). Additionally, analyses of the subjective perception of pain and reaction time indicated that laser stimuli preceded by pain cues were rated as more painful than those signaling non-pain expectancy and were associated with faster responses. Differences between groups were not found. The present findings suggest the presence of dysfunction in pain expectation mechanisms in fibromyalgia that eventually may make it difficult for patients to correctly interpret signs that prevent pain symptoms. Furthermore, the abnormal pattern in pain expectancy displayed by fibromyalgia patients could result in ineffective pain coping strategies. Understanding the neural correlates of pain processing and its modulatory factors is crucial to identify treatments for chronic pain syndromes.

ABSTRACT

Background: Opportunistic prostate-specific antigen (PSA) screening may reduce prostate cancer mortality risk but is associated with false positive results, biopsy complications and overdiagnosis. Although different organisations have emphasised the importance of shared decision making (SDM) to assist men in deciding whether to undergo prostate cancer screening, recent evaluations show that the available decision aids fail to facilitate SDM, mainly because they do not consider the patients' perspective in their design. We aim to systematically develop and test a patient decision aid to promote SDM in prostate cancer screening, following the Knowledge to Action framework. Methods: (1) Feasibility study: a quantitative survey evaluating the population and clinician (urologists and general practitioners) knowledge of the benefits and risks derived from PSA determination and the awareness of the available recommendations. Focus groups to explore the challenges patients and clinicians face when discussing prostate cancer screening, the relevance of a decision aid and how best to integrate it into practice. (2) Patient decision aid development: Based on this data, an evidence-based multicomponent SDM patient decision aid will be developed. (3) User-testing: an assessment of the prototype of the initial patient decision aid through a user-testing design based on mix-methods (questionnaire and semi-structured review). The decision aid will be refined through several iterative cycles of feedback and redesign. (4) Validation: an evaluation of the patient decision aid through a cluster-randomised controlled trial. Discussion: The designed patient decision aid will provide balanced information on screening benefits and risks and should help patients to consider their personal preferences and to take a more active role in decision making. Conclusions: The well-designed patient decision aid (PDA) will provide balanced information on screening benefits and risks and help patients consider their personal preferences.

ABSTRACT

BACKGROUND: One of the major cognitive deficits in fibromyalgia has been linked to the hypervigilance phenomenon. It is mainly reflected as a negative bias for allocating attentional resources towards both threatening and pain-related information. Although the interest in its study has recently grown, the neural temporal dynamics of the attentional bias in fibromyalgia still remains an open question. METHOD: Fifty participants (25 fibromyalgia patients and 25 healthy control subjects) performed a dot-probe task. Two types of facial expressions (pain-related and neutral) were employed as signal stimuli. Then, as a target stimulus, a single dot replaced the location of one of these two faces. Event-related potentials (ERP) in response to facial expressions and target stimulation (i.e., dot) were recorded. Reaction time (RT) and accuracy measures in the experimental task were collected as behavioural outcomes. RESULTS: Temporal dynamics of brain electrical activity were analysed on two ERP components (P2 and N2a) sensitive to the facial expressions meaning. Pain-related faces elicited higher frontal P2 amplitudes than neutral faces for the whole sample. Interestingly, an interaction effect between group and facial expressions was also found showing that pain-related faces elicited enhanced P2 amplitudes (at fronto-central regions, in this case) compared to neutral faces only when the group of patients was considered. Furthermore, higher P2 amplitudes were observed in response to pain-related faces in patients with fibromyalgia compared to healthy control participants. Additionally, a shorter latency of P2 (at centro-parietal regions) was also detected for pain-related facial expressions compared to neutral faces. Regarding the amplitude of N2a, it was lower for patients as compared to the control group. Non-relevant effects of the target stimulation on the ERPs were found. However, patients with fibromyalgia exhibited slower RT to locate the single dot for incongruent trials as compared to congruent and neutral trials. CONCLUSIONS: Data suggest the presence of an attentional bias in fibromyalgia that it would be followed by a deficit in the allocation of attentional resources to further process pain-related information. Altogether the current results suggest that attentional biases in fibromyalgia might be explained by automatic attentional mechanisms, which seem to be accompanied by an alteration of more strategic or controlled attentional components.

ABSTRACT

OBJECTIVE: Cognitive dysfunction in fibromyalgia has become a key symptom considered by patients as more disabling than pain itself. Experimental evidence from neuropsychological and neuroimaging studies indicates that such cognitive impairments are especially robust when patients need to set in motion working memory processes, suggesting the existence of an altered functioning underlying the cerebral cortices of the frontoparietal memory network. However, the temporal dynamics of working memory subprocesses have not yet been explored in fibromyalgia. SUBJECTS: Thirty-six right-handed women participated in the experiment, comprising 18 patients with fibromyalgia and 18 healthy controls. METHODS: Event-related potentials (ERPs) and behavioral responses were recorded while participants were engaged in a two-back working memory task. Principal component analyses were used to define and quantify the ERP components associated with working memory processes. RESULTS: Patients with fibromyalgia exhibited worse performance than the control group, as revealed by their number of errors in the working memory task. Moreover, both scalp parieto-occipital P2 and parieto-occipital P3 amplitudes were lower for patients than for healthy control participants. Regression analyses revealed that lower P3 amplitudes were observed in those patients with fibromyalgia reporting higher pain ratings. CONCLUSIONS: The present results suggest that both encoding of information (as reflected by P2) and subsequently context updating and replacement (as seen in lower P3 amplitudes), as a part of working memory subprocesses, are impaired in fibromyalgia. Studying the temporal dynamics of working memory through the use of ERP methodology is a helpful approach to detect specific impaired cognitive mechanisms in this chronic pain syndrome. These new data could be used to develop more specific treatments adapted for each patient.

ABSTRACT

Factor V is an essential clotting factor that plays a key role in the blood coagulation cascade on account of its procoagulant and anticoagulant activity. Eighty percent of circulating factor V is produced in the liver and the remaining 20% originates in the α-granules of platelets. In humans, the factor V gene is about 80 kb in size; it is located on chromosome 1q24.2, and its cDNA is 6914 bp in length. Furthermore, nearly 190 mutations have been reported in the gene. Factor V deficiency is an autosomal recessive coagulation disorder associated with mutations in the factor V gene. This hereditary coagulation disorder is clinically characterized by a heterogeneous spectrum of hemorrhagic manifestations ranging from mucosal or soft-tissue bleeds to potentially fatal hemorrhages. Current treatment of this condition consists in the administration of fresh frozen plasma and platelet concentrates. This article describes the cases of two patients with severe factor V deficiency, and of their parents. A high level of mutational heterogeneity of factor V gene was identified, nonsense mutations, frameshift mutations, missense changes, synonymous sequence variants and intronic changes. These findings prompted the identification of a new mutation in the human factor V gene, designated as Jaén-1, which is capable of altering the procoagulant function of factor V. In addition, an update is provided on the prospects for the treatment of factor V deficiency on the basis of yet-to-be-developed recombinant products or advanced gene and cell therapies that could potentially correct this hereditary disorder.

ABSTRACT

Previous research has shown a consistent association among genetic factors, psychological symptoms and pain associated with fibromyalgia. However, how these symptoms interact to moderate genetic factors in fibromyalgia has rarely been studied to date. The present research investigates whether psychological symptoms can moderate the effects of catechol-O-methyltransferase on pain and fatigue. A total of 108 women diagnosed with fibromyalgia and 77 healthy control participants took part in the study. Pain, fatigue, and psychological symptoms (anxiety, depression, pain catastrophizing, fear of pain and fear of movement) were measured by self-report questionnaires. Two types of statistical analyses were performed; the first was undertaken to explore the influences of COMT genotypes on clinical symptoms by comparing patients with fibromyalgia and healthy controls. In the second analysis, moderation analyses to explore the role of psychological symptoms as potential factors that moderate the relationship between pain/fatigue and COMT genotypes were performed. The main results indicated that patients carrying the Met/Met genotype reported significantly higher levels of fatigue than heterozygote carriers (i.e., Met/Val genotype) and higher levels of fatigue, but not significantly different, than Val homozygote carriers. Among patients with fibromyalgia carrying methionine alleles (i.e., Met/Met + Met/Val carriers), only those who scored high on medical fear of pain, experienced an intensified feeling of fatigue. Thus, the present research suggests that fear of pain, as a psychological symptom frequently described in fibromyalgia may act as a moderating factor in the relationship between the Met allele of the COMT gene and the increase or decrease in self-reported fatigue. Although further research with wider patient samples is needed to confirm the present findings, these results point out that the use of psychological interventions focused on affective symptomatology might be a useful tool to reduce the severity of fibromyalgia.

ABSTRACT

Growing research has reported the presence of a clear impairment of working memory functioning in fibromyalgia. Although different genetic factors involving dopamine availability (i.e, the COMT gene) have been associated with the more severe presentation of key symptoms in fibromyalgia, scientific evidence regarding the influence of COMT genotypes on cognitive impairment in these patients is still lacking. To this end, 167 participants took part in the present investigation. Working memory performance was assessed by the application of the SST (Spatial Span Test) and LNST (Letter and Number Sequence Test) belonging to the Weschler Memory Scale III. Significant working memory impairment was shown by the fibromyalgia patients. Remarkably, our results suggest that performance according to different working memory measures might be influenced by different genotypes of the COMT gene. Specifically, fibromyalgia patients carrying the Val/Val genotype exhibited significantly worse outcomes for the span of SST backward, SST backward score, SST total score and the Working Memory Index (WMI) than the Val/Val healthy carriers. Furthermore, the Val/Val patients performed worse on the SST backward and SST score than heterozygotes. Our findings are the first to show a link between the COMT gene and working memory dysfunction in fibromyalgia, supporting the idea that higher COMT enzyme activity would contribute to more severe working memory impairment in fibromyalgia.

ABSTRACT

Intracranial germ cell tumors (GCT) account for less than 5% of all central nervous system tumors in children in Western countries. Approximately 40% are nongerminomatous GCT (NGGCT). Despite correct treatment, 16% to 47% of the patients will relapse. There are no standard approaches in case of recurrence, and treatment in this situation remains a challenge. We report three patients diagnosed with relapsed intracranial NGGCT treated with gemcitabine, paclitaxel, and oxaliplatin, in whom the tumor showed a remarkable response with normalization of tumor markers.

ABSTRACT

Pain experience involves a complex relationship between sensory and both emotional and cognitive factors, which appear to be mediated by different neural pathways. Previous evidence has shown that whereas conscious processing of unpleasant stimuli enhances pain perception, the influence of emotions on pain under unaware conditions is much less known. The need to better characterise the relationship between pain processing and emotional factors is crucial for dealing with chronic pain conditions. Therefore, the present study aimed to explore the neural correlates relating to the influence of visual masking emotional stimulation on the processing of painful stimuli in chronic pain patients suffering from fibromyalgia (FM). Twenty FM and 22 healthy control (HC) women participated in the study. The experimental masking paradigm consisted of a rapid succession of two types of stimuli, where a masked picture (neutral, negative or pain-related) was followed by a laser stimulus (painful or not painful). LEP activity was recorded at sixty scalp electrodes. An LEP-amplitude approach was used to quantify the main cerebral waves linked to pain response. ANOVAs indicated that the posterior regions of the P1 component were sensitive to experimental manipulation (p<0.05). Specifically, FM patients showed higher amplitudes to painful stimuli preceded by pain-related pictures compared with painful trials preceded by other emotional pictures. The FM group also showed greater amplitudes than those in the HC group in P2a and P2b waves. In addition to the scalp data, at the neural level the posterior cingulate cortex, lingual gyrus and insular cortex showed higher activation in the FM group than in the HC group. Our findings show an early cerebral modulation of pain (as reflected by the P1) in FM patients, suggesting that only pain-related information, even when it is unconsciously perceived, is capable to enhance exogenous (automatic) attention, increasing the neural activity involved in processing painful stimulation. Further research is needed to fully understand unconscious emotional influences on pain in fibromyalgia.

ABSTRACT

OBJETIVOS: Evaluar si persiste el beneficio sobre los factores de riesgo cardiovascular (FRCV) a los 5 años de una intervención intensiva en estilos de vida (EV) que duró 2 años, en pacientes con hiperfibrinogenemia y riesgo cardiovascular moderado o alto. DISEÑO: Estudio observacional prospectivo multicéntrico. Emplazamiento: Trece Centros de Atención Primaria de Barcelona y Baix Llobregat. PARTICIPANTES: Un total de 300 pacientes que finalizaron el estudio EFAP (146 del grupo intervención y 154 del control). INTERVENCIONES: El estudio EFAP, realizado con pacientes con cifras de colesterol normal y fibrinógeno elevado, mostró que las intervenciones sobre el estilo de vida son eficaces en la reducción de FRCV. Finalizado el estudio EFAP, los 2 grupos siguieron los controles habituales. Pasados 5 años evaluamos los 2 grupos. Mediciones principales: Edad, sexo, FRCV (diabetes, dislipidemia, hipertensión arterial, obesidad), analítica (fibrinógeno, glucosa, hemograma, colesterol, triglicéridos), presión arterial, peso, talla, índice de masa corporal (IMC), hábitos tóxicos (tabaco y alcohol), REGICOR. RESULTADOS: A los 5 años, el grupo intervención presentó respecto al control menor perímetro abdominal (98 y 101 cm, respectivamente; p = 0,043), menor peso (76,30 y 75,04kg, respectivamente; p < 0,001) e IMC (29,5 y 30, 97 kg/m2; p = 0,018). El nivel de fibrinógeno fue inferior en el grupo intervención (330,33 y 320,27 mg/dl respectivamente; p < 0,001), y riesgo REGICOR también fue inferior en el grupo intervención (5,65 y 5,59 respectivamente; p < 0,06). CONCLUSIÓN: El beneficio de una intervención intensiva en EV durante 2 años para reducir los FRCV persiste a los 5 años, pero disminuye su intensidad con el tiempo. Se recomienda repetir periódicamente las intervenciones para mantener el efecto beneficioso sobre los EV


OBJECTIVES: To determine whether the benefit on cardiovascular risk factors (CVRF) persists 5 years after an intensive intervention in lifestyle (LS) that lasted 2 years, in patients with hyperfibrinogenaemia and moderate or high cardiovascular risk. DESIGN: multicentre prospective observational study. LOCATION: 13 Primary Care Centres in Barcelona and Baix Llobregat. PARTICIPANTS: A total of 300 patients who completed the EFAP study (146 intervention group, 154 control group). INTERVENTIONS: The EFAP study, conducted on patients with normal cholesterol and elevated fibrinogen showed that lifestyle interventions are effective in reducing CVRF. After the EFAP study, the 2 groups followed the usual controls, and re-assessed after 5 years. MAIN MEASUREMENTS: Age, gender, cardiovascular diseases (CVD) (diabetes, dyslipidaemia, hypertension, obesity), laboratory parameters (fibrinogen, glucose, full blood count, cholesterol, triglycerides), blood pressure, weight, height, body mass index (BMI), tobacco and alcohol use, REGICOR. RESULTS: At 5 years, the intervention group had a lower abdominal circumference (98 and 101cm, respectively, P = .043), a lower weight (76.30 and 75.04 kg, respectively, P < .001), and BMI (29.5 and 30.97 kg/m2, P = .018). Fibrinogen level was lower in the intervention group (330.33 and 320.27 mg/dl respectively, P < .001), and REGICOR risk was also lower in the intervention group (5.65 and 5.59 respectively, P < .06). CONCLUSION: The benefit of an intensive intervention in LS for 2 years to reduce CVRF persists at 5 years, but decreases its intensity over time. It is recommended to repeat the interventions periodically to maintain the beneficial effect on LS
