Social cognition in first-degree relatives of bipolar disorder: Theory of Mind and nonverbal sensitivity.

Social cognition might be impaired in first degree relatives (FDR) of BD but existing research shows controversial results about social cognitive impairments in this population. The aim of this study was to assess Theory of Mind (ToM) and nonverbal sensitivity in FDR of BD and compare the results with those of two groups of persons with remitted bipolar disorder (BD), type I and II, and a control group. Social cognitive ability was examined in first degree relatives of BD, with a biological parent, offspring or sibling diagnosed with the disorder. For this study, 37 FDRs of bipolar patients, 37 BD I, 40 BD II and 40 control participants were recruited. Social cognition was explored by means of the Reading the Mind in the Eyes Test and the MiniPONS. Results showed a significant impairment in FDR of BD in the ToM task, but not in nonverbal sensitivity. Performance of FDRs in social cognition is better than that of BDs (either type I or type II) but worse when compared with that of healthy individuals without a family history of psychiatric disorders. Nevertheless, no differences were found between BD I and BD II groups. Males and older participants showed a worse performance in all groups. Group family therapy with FDRs of BD might include training in the recognition of nonverbal cues, which might increase the understanding of their familiars with BD, in order to modify communication abilities.

Theory of mind in remitted bipolar disorder: Interpersonal accuracy in recognition of dynamic nonverbal signals.

A relatively unexplored aspect in bipolar disorder (BD) is the ability to accurately judge other´s nonverbal behavior. To explore this aspect of social cognition in this population is particularly meaningful, as it may have an influence in their social and interpersonal functioning. The aim of this research was to study interpersonal accuracy (IPA) in remitted BDs, that is, the specific skills that fall under the general term Theory of Mind (ToM). Study participants included 119 remitted individuals with BD (70 BD I and 49 BD II), and they were compared with a group of 39 persons diagnosed with unipolar depression (UD) and 119 control participants. The MiniPONS was used to test the whole spectrum of nonverbal cues as facial expressions, body language and voice. Results indicated a superiority of the control group with statistically significant differences both in the performance in the MiniPONS (number of right answers) and in each of the areas evaluated by this test. BD groups, in recognition of the meaning of gestures in face, body and voice intonation, performed significantly worse than controls. ANCOVA analysis controlling the effect of age shows that control group performed significantly better compared to clinical groups, and there were no differences between UD and BD groups. The results indicate a deficit in IPA and suggest that better comprehension of deficiencies in interpersonal accuracy in BD may help to develop new training programs to improve in these patients the understanding of others, which might have a positive impact in their psychosocial functionality, and thus lead to the objective of functional rehabilitation.

Intrathecal administration of autologous mesenchymal stromal cells for spinal cord injury: Safety and efficacy of the 100/3 guideline.

BACKGROUND AIMS: Cell therapy with autologous mesenchymal stromal cells (MSCs) in patients with spinal cord injury (SCI) is beginning, and the search for its better clinical application is an urgent need. METHODS: We present a phase 2 clinical trial in patients with chronic SCI who received three intrathecal administrations of 100 x 106 MSCs and were followed for 10 months from the first administration. Efficacy analysis was performed on nine patients, and safety analysis was performed on 11 patients. Clinical scales, urodynamic, neurophysiological and neuroimaging studies were performed previous to treatment and at the end of the follow-up. RESULTS: The treatment was well-tolerated, without any adverse event related to MSC administration. Patients showed variable clinical improvement in sensitivity, motor power, spasms, spasticity, neuropathic pain, sexual function or sphincter dysfunction, regardless of the level or degree of injury, age or time elapsed from the SCI. In the course of follow-up three patients, initially classified as ASIA A, B and C, changed to ASIA B, C and D, respectively. In urodynamic studies, at the end of follow-up, 66.6% of the patients showed decrease in postmicturition residue and improvement in bladder compliance. At this time, neurophysiological studies showed that 55.5% of patients improved in somatosensory or motor-evoked potentials, and that 44.4% of patients improved in voluntary muscle contraction together with infralesional active muscle reinnervation. CONCLUSIONS: The present guideline for cell therapy is safe and shows efficacy in patients with SCI, mainly in recovery of sphincter dysfunction, neuropathic pain and sensitivity.

What your eyes tell me: Theory of mind in bipolar disorder.

The aim of this study was to assess social- perceptual Theory of Mind in bipolar disorder (BD). 112 euthymic participants with BD I or BD II (65 with BD I and 47 with BD II) were compared to a group of 112 persons with no psychiatric diagnosis and 43 with unipolar depression (UD). They completed the task of the "Reading the Mind in the Eyes" (RMET). The results show that participants with BD, I and II, as well as the group with UD performed significantly more poorly than the control group. As for the wrong answers, BDs mostly chose positive valence stimuli, while the UD group chose negative valence items. The main limitation of this research is related to the characteristics of the cross-sectional study. It cannot detect at what time of the disorder these differences in emotion processing will appear with more intensity. As for future research, we suggest interventions to improve the deficits in ToM in bipolar persons. The use of the RMET in the first stages of BD II could help to facilitate a correct diagnosis.

Influence of attention deficit hyperactivity disorder symptoms on quality of life and functionality in adults with eating disorders.

INTRODUCTION: Eating disorders (ED) have been linked to attention deficit hyperactivity disorder (ADHD) because they present some symptoms in common. The aim of this study was to explore the influence on ED of symptoms suggestive of adult ADHD and how these symptoms affect the clinical presentation of adult patients. A further aim was to assess the impact of ADHD symptoms on quality of life and feelings of disability. METHOD: Participants comprised 89 patients diagnosed with ED according to DSM-5 criteria. The ASRS v.1.1 was used to divide them into two groups depending on whether they presented symptoms suggestive of adult ADHD or not, using a cut-off point of 4. Subsequently, we administered the EAT-40, BITE, BIS-11, SDI and Q-LES-Q scales. RESULTS: Patients diagnosed with ED who also had symptoms suggestive of ADHD presented a higher number and severity of eating disorder symptoms, greater motor and cognitive impulsivity, increased dysfunction and a poorer quality of life. CONCLUSIONS: The results indicate that on average, patients with eating disorders and ADHD symptoms presented more and worse eating disorder symptoms, greater impulsivity, increased dysfunction and a poorer quality of life. It is therefore important to assess the presence of ADHD symptoms in patients with ED due to the implications for prognosis and progression.

Influencia de los síntomas del trastorno por déficit de atención con iperactividad en adultos en la calidad de vida y funcionalidad de los trastornos de conducta alimentaria / Influence of attention deficit hyperactivity disorder symptoms on quality of life and functionality in adults with eating disorders

Introducción. Los trastornos de conducta alimentaria (TCA) se han relacionado con el trastorno de déficit de atención e hiperactividad (TDAH), ya que algunos síntomas son comunes. Este estudio tiene como objetivo explorar la influencia de los síntomas sugestivos de TDAH del adulto en los TCA y de cómo estos síntomas influyen en la clínica y presentación de los pacientes en la vida adulta. También se pretende valorar la repercusión de los mismos en la calidad de vida y los sentimientos de discapacidad. Metodología. Incluimos 89 pacientes diagnosticados de TCA según criterios DSM-5. Se empleó la ASRS v.1.1. para dividirlos en dos grupos en función de si presentaban clínica sugestiva de TDAH del adulto o no, según un punto de corte establecido en 4. Posteriormente se administraron las escalas EAT-40, BITE, BIS-11, SDI y Q-ES-Q. Resultados. Los pacientes con diagnóstico de TCA y sintomatología sugestiva de TDAH presentan mayor sintomatología alimentaria y más severa, mayor impulsividad motora y cognitiva, mayor disfunción y peor calidad de vida.Conclusiones. Los resultados permiten comprobar que los pacientes con TCA y sintomatología de TDAH presentan, por término medio, peor sintomatología alimentaria, de mayor severidad, mayor impulsividad, mayor disfunción y peor calidad de vida. Por tanto, se considera importante evaluar la presencia de síntomas TDAH en pacientes con TCA por las implicaciones en el pronóstico y la evolución (AU)

Repeated subarachnoid administrations of autologous mesenchymal stromal cells supported in autologous plasma improve quality of life in patients suffering incomplete spinal cord injury.

BACKGROUND AIMS: Cell therapy with mesenchymal stromal cells (MSCs) offers new hope for patients suffering from spinal cord injury (SCI). METHODS: Ten patients with established incomplete SCI received four subarachnoid administrations of 30 × 106 autologous bone marrow MSCs, supported in autologous plasma, at months 1, 4, 7 and 10 of the study, and were followed until the month 12. Urodynamic, neurophysiological and neuroimaging studies were performed at months 6 and 12, and compared with basal studies. RESULTS: Variable improvement was found in the patients of the series. All of them showed some degree of improvement in sensitivity and motor function. Sexual function improved in two of the eight male patients. Neuropathic pain was present in four patients before treatment; it disappeared in two of them and decreased in another. Clear improvement in bladder and bowel control were found in all patients suffering previous dysfunction. Before treatment, seven patients suffered spasms, and two improved. Before cell therapy, nine patients suffered variable degree of spasticity, and 3 of them showed clear decrease at the end of follow-up. At this time, nine patients showed infra-lesional electromyographic recordings suggesting active muscle reinnervation, and eight patients showed improvement in bladder compliance. After three administrations of MSCs, mean values of brain-derived neurotrophic factor, glial-derived neurotrophic factor, ciliary neurotrophic factor, and neurotrophin 3 and 4 showed slight increases compared with basal levels, but without statistically significant difference. CONCLUSIONS: Administration of repeated doses of MSCs by subarachnoid route is a well-tolerated procedure that is able to achieve progressive and significant improvement in the quality of life of patients suffering incomplete SCI.
