Trastorno límite de la personalidad (TLP), experiencias adversas tempranas y sesgos cognitivos: una revisión sistemática

Introducción: La investigación actual y los artículos rastreados sobre adversidad temprana y sesgos cognitivos en pacientes con trastorno límite de la personalidad (TLP) evidencian la relación entre estas variables y la gravedad de los síntomas clínicos de este trastorno. Objetivo: Revisar sistemáticamente la evidencia de la relación entre adversidad temprana, sesgos cognitivos y agudización de los síntomas del TLP. El vacío investigativo tiene que ver con el tipo específico de adversidad temprana y su relación con el tipo específico de sesgos cognitivos y el curso del TLP de pacientes con este diagnóstico. Metodología: Se realizó una revisión sistemática de la literatura y para reportar la evidencia se utilizó la versión 2020 de la declaración Prisma. Las bases de datos consultadas fueron Scopus, Pubmed, Web of Science y PsycInfo. En la búsqueda también se incluyeron bases de datos de literatura gris como Google Académico, Open Gray y WorldCat. Resultados: En total se incluyeron en el estudio 13 artículos que satisficieron criterios de originalidad, temática estudiada (adversidad temprana, funcionamiento cognitivo y sintomatología límite) y población indicada (pacientes con diagnóstico de TLP). Conclusiones: Si bien existe evidencia de que la adversidad temprana en general es un factor de riesgo para el TLP, se necesita más investigación para comprender los tipos específicos de adversidad que pueden estar más fuertemente relacionados con el desarrollo del TLP. Si bien algunos estudios han identificado sesgos cognitivos en individuos con TLP, poco se conoce sobre el modo en que estos sesgos se desarrollan y cambian con el tiempo, o según la etapa de exposición del paciente a la adversidad temprana.

Introduction: Current research and articles on early adversity and cognitive biases in patients with borderline personality disorder (BPD) demonstrate the relationship between these variables and the severity of the clinical symptoms of this disorder. Objective: The aim was to systematically review the evidence of the relationship between early adversity, cognitive biases, and exacerbation of symptoms of borderline personality disorder. The research gap concerns the particular type of early adversity and its relationship with the specific type of cognitive biases and the course of BPD in patients with this diagnosis. Methodology: We conducted a systematic literature review, and the Prisma statement version 2020 was used to report the evidence. The databases consulted were Scopus, Pubmed, Web of Science, and PsycInfo. Gray literature databases, such as Google Scholar, Open Gray, and WorldCat, were also included in the search. Results: We included 13 articles in the study that met the criteria for originality, studied theme (early adversity, cognitive functioning, and borderline symptomatology), and target population (patients diagnosed with a personality disorder). Conclusions: We found that while there is evidence that early adversity, in general, is a risk factor for BPD, further research is needed to understand the specific types of adversity that may be more strongly related to the development of BPD. In addition, although some studies have identified cognitive biases in individuals with BPD, little is known about how these biases develop and change over time or according to the stage of the patient's exposure to early adversity.

Impact of the COVID-19 Pandemic on the Mental Health of Nurses and Auxiliary Nursing Care Technicians-A Voluntary Online Survey.

Pandemics impose an immense psychological burden on healthcare workers due to a combination of workplace stressors and personal fears. Nurses and auxiliary nursing care technicians (ANCTs) are on the front line of this pandemic and form the largest group in healthcare practice. The aim of this study is to determine the symptoms of depression and/or anxiety among nurses and ANCTs during the periods known as the first wave (March-June) and second wave (September-November) of theCOVID-19 pandemic in Spain. An observational cross-sectional study was carried out using an anonymous, self-administered questionnaire among nurses and ANCTs practising in Spain. During the first period, 68.3% and 49.6% of the subjects presented anxiety and depression, respectively, decreasing in the second period (49.5% for anxiety and 35.1% for depression). There were statistically significant differences between the different categories and periods (p < 0.001). The COVID-19 pandemic has negatively influenced mental health in nurses and ANCTs. Mental health should be monitored and coping strategies promoted to improve the health, productivity and efficiency of these professionals.

Knowledge and Practice of Health Professionals in the Management of Dysphagia.

The aim of this study was to determine healthcare providers' knowledge and practices about dysphagia. A descriptive cross-sectional study was carried out based on a self-administered and anonymous questionnaire addressed to healthcare providers in Spain. A total of 396 healthcare providers participated in the study. Of these, 62.3% knew the definition of dysphagia as a swallowing disorder. In addition, up to 39.2% of the participants reported that they did not know whether the EatingAssessmentTool (EAT-10) dysphagia screening test was usedin their own clinical settings. Similarly, up to 49.1% of them did not know the ClinicalExaminationVolume-Viscosity (MECV-V) method. Nearly all participants (98.8%) reported that thickeners must be used forall liquids administered to patients. A higher percentage of respondents based the choice of texture on patient's tolerance (78.2%) rather than on the MECV-V result (17.3%). In addition,76.4% of the professionals had witnessed a bronchoaspiration; after it, 44.4% (n = 175) of them reported the appearance of pneumonia, and 14.5% (n = 57) the death of the patient (p = 0.005). The participants revealeda moderate/low knowledge ofthe definition, diagnosis, and clinical management of liquid dysphagia, which indicates some room for improvements.

Eating Habits and Physical Activity of the Spanish Population during the COVID-19 Pandemic Period.

Due to the pandemic situation caused by the COVID-19 infection, some governments have implemented house confinement measures. The objective of our study is to learn the dietary patterns, consumption, and physical activity of the Spanish population before and during the period of confinement by COVID-19. A cross-sectional descriptive study based on a questionnaire during May 2020, coinciding with the period of confinement and the step forward into Phase 1, is carried out. During confinement, the adherence to the Mediterranean Diet increases (8.0% versus 4.7%; p < 0.001). No socio-demographic variables show statistical significance (p < 0.05) regarding good adherence to the Mediterranean Diet (MD) before and during confinement. During confinement, consumption of homemade baking shows a higher increase (0.28% versus 4.60%; p = 0.004). During confinement, the number of subjects that practice exercise decreases (29.4% versus 28.8%; p = 0.004), as well as the time spent exercising (more than an hour, 26.6% versus 14.7%, p = 0.001). Mediterranean Diet adherence slightly increases during confinement, although consumption of 'unhealthy' food also increases. Moreover, the number of subjects that practice physical activity, as well as the time spent on it weekly, decreases.

Giant Dumbbell-Shaped Thoracic Schwannoma in an Elderly Patient Resected Through a Single-Stage Combined Laminectomy and Video-Assisted Thoracoscopy: Surgical Strategy and Technical Nuances.

BACKGROUND: Dumbbell-shaped schwannomas involving the spinal canal, the intervertebral foramen, and the thoracic cavity are rare lesions. Surgical treatment represents a challenge, and there is no consensus regarding ideal management. Two major surgical routes have been used: combined laminectomy and open thoracotomy or posterolateral extrapleural approach with wide bone removal. This report describes a relatively easy surgical strategy, combined laminectomy and thoracoscopy, which allows safe resection under an adequate view with low risk of spinal instability, pain, or respiratory problems. CASE DESCRIPTION: A 74-year-old man presented with rapidly progressing motor impairment caused by a dumbbell-shaped, 65-mm, Eden type III lesion at the T5 level. Magnetic resonance imaging showed an intraspinal-extradural mass extending into the chest cavity and causing severe spinal cord compression. The patient underwent single-stage surgery performed by a neurosurgical and thoracic team. The extradural and foraminal tumor components were first removed through a 1-level laminectomy with foraminotomy and without facetectomy. Subsequently, video-assisted thoracic surgery was performed to approach the anterior paraspinal component. Total tumor removal, confirmed with postoperative magnetic resonance imaging, was achieved. Pathologic diagnosis was schwannoma. The postoperative course was uneventful. The patient's neurologic deficits resolved, and he experienced minimal pain after the operation. CONCLUSIONS: A single-stage operation using combined laminectomy and video-assisted thoracic surgery is a safe and efficacious strategy for achieving total removal of dumbbell-shaped thoracic schwannomas, even in cases involving giant lesions and elderly patients.

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.

Cell therapy with autologous mesenchymal stromal cells in post-traumatic syringomyelia.

BACKGROUND AIMS: Recently, clinical studies show that cell therapy with mesenchymal stromal cells (MSCs) improves the sequelae chronically established in paraplegic patients, being necessary to know which of them can obtain better benefit. METHODS: We present here a phase 2 clinical trial that includes six paraplegic patients with post-traumatic syringomyelia who received 300 million MSCs inside the syrinx and who were followed up for 6 months. Clinical scales, urodynamic, neurophysiological, magnetic resonance (MR) and studies of ano-rectal manometry were performed to assess possible improvements. RESULTS: In all the cases, MR at the end of the study showed a clear reduction of the syrinx, and, at this time, signs of improvement in the urodynamic studies were found. Moreover, four patients improved in ano-rectal manometry. Four patients improved in neurophysiological studies, with signs of improvement in evoked potentials in three patients. In the American Spinal Injury Association (ASIA) assessment, only two patients improved in sensitivity, but clinical improvement in neurogenic bowel dysfunction was observed in four patients and three patients described improvement in bladder dysfunction. Spasms reduced in two of the five patients who had them previous to cell therapy, and spasticity was improved in the other two patients. Three patients had neuropathic pain before treatment, and it was reduced or disappeared completely during the study. Only two adverse events ocurred, without relation to the cell therapy. CONCLUSIONS: Cell therapy can be considered as a new alternative to the treatment of post-traumatic syringomyelia, achieving reduction of syrinx and clinical improvements in individual patients.

Thymoma dissemination through the thoracic intervertebral foramen: Pleural recurrence resulting in spinal cord compression.

BACKGROUND: Spinal dissemination of thymic tumors is rare but should be considered in the differential diagnosis of thoracic dumbbell-shaped lesions and/or vertebral tumors, irrespective of the time since the initial diagnosis. CASE DESCRIPTION: A 63-year-old man, with a history of invasive type AB thymoma treated 21 years ago, newly presented to the hospital with a dumbbell-shaped T8-T9 lesion compressing the spinal cord. A review of the literature showed only 16 previous cases of thymic tumors with thoracic spine involvement. Here, we report the lengthiest interval between the initial tumor diagnosis and the detection of spinal involvement, that was secondary to a pleural recurrence from his thymoma. The patient did well following successful excision of the intraspinal mass which had encased the T8 nerve root. CONCLUSION: Spinal dissemination of thymic tumors can occur due to vertebral metastasis or to extension of a pleural recurrence through the intervertebral foramen. Definitive treatment for spinal lesions should be considered to provide adequate cord decompression.

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.

An approach to personalized cell therapy in chronic complete paraplegia: The Puerta de Hierro phase I/II clinical trial.

BACKGROUND AIMS: Cell transplantation in patients suffering spinal cord injury (SCI) is in its initial stages, but currently there is confusion about the results because of the disparity in the techniques used, the route of administration, and the criteria for selecting patients. METHODS: We conducted a clinical trial involving 12 patients with complete and chronic paraplegia (average time of chronicity, 13.86 years; SD, 9.36). The characteristics of SCI in magnetic resonance imaging (MRI) were evaluated for a personalized local administration of expanded autologous bone marrow mesenchymal stromal cells (MSCs) supported in autologous plasma, with the number of MSCs ranging from 100 × 10(6) to 230 × 10(6). An additional 30 × 10(6) MSCs were administered 3 months later by lumbar puncture into the subarachnoid space. Outcomes were evaluated at 3, 6, 9 and 12 months after surgery through clinical, urodynamic, neurophysiological and neuroimaging studies. RESULTS: Cell transplantation is a safe procedure. All patients experienced improvement, primarily in sensitivity and sphincter control. Infralesional motor activity, according to clinical and neurophysiological studies, was obtained by more than 50% of the patients. Decreases in spasms and spasticity, and improved sexual function were also common findings. Clinical improvement seems to be dose-dependent but was not influenced by the chronicity of the SCI. CONCLUSION: Personalized cell therapy with MSCs is safe and leads to clear improvements in clinical aspects and quality of life for patients with complete and chronically established paraplegia.
