RESUMO

El síndrome de Parsonage-Turner o plexopatía braquial idiopática es una inflamación total o parcial del plexo braquial cuya presentación típica es una omalgia intensa y súbita, seguida de debilidad braquial y amiotrofia precoz. La etiología es desconocida, aunque se propone un mecanismo inmunomediado.El trasplante de progenitores hematopoyéticos es un tratamiento bien establecido de las neoplasias hematológicas y tiene un papel creciente en el tratamiento de enfermedades autoinmunes. Los efectos adversos neurológicos son probablemente infradiagnosticados.La asociación del síndrome de Parsonage-Turner y el trasplante de progenitores hematopoyéticos es muy poco conocida. Describimos dos casos clínicos de plexopatía braquial idiopática tras trasplante de células stem (progenitores) hematopoyéticas (TPH).La reconstitución del sistema inmune tras un trasplante de progenitores hematopoyéticos puede ser un desencadenante de plexopatía braquial, aunque se necesitan más estudios para entender la fisiopatología de esta entidad y establecer su relación causal con el trasplante.

RESUMO

The identification of the risk factors of alcohol consumption in youths is crucial for early interventions focused on reducing harmful alcohol use. In our study, 82 college students (40 healthy control (CO group) and 42 with risky alcohol use (RAU group) determined by AUDIT questionnaire) between the ages of 18 and 25 years underwent a comprehensive neuropsychological assessment covering emotional and cognitive functioning. Their resting-state activity was also recorded with an EEG for 10 min with their eyes open (EO) and 10 min with their eyes closed (EC) and analyzed using the Fitting Oscillations & One-Over-F (FOOOF) paradigm. After adjusting for sex, those in the RAU group had higher emotional dysregulation and impulsivity traits. The RAU girls presented more emotional regulation problems, such as dysregulation and negative urgency compared with the RAU boys. The RAU youths had significantly worse functioning in several cognitive domains, such as sustained attention, verbal memory, and executive functions. Cognitive network analysis revealed a different pattern of connections in each group showing that in the RAU group, the verbal memory domain had the highest connection with other cognitive functions. The EEG analyses did not reveal any significant differences between the CO and the RAU groups. However, we observed only in the EO condition that boys the from the RAU group displayed a higher theta/beta ratio than the RAU girls, whereas these differences were not observed within the CO group. Our findings highlight the need to explore more deeply the emotional, cognitive and brain changes underlying the RAU in young people.

RESUMO

INTRODUCTION: The objective is to produce an average brain activation mapping template in healthy children using functional magnetic resonance imaging (fMRI), with specific paradigms for activating inhibitory attention and working memory functions. SUBJECTS AND METHODS: A nutritional and neuropsychological evaluation was performed on 87 right-handed children. The inclusion criteria were met by 30 children (15 boys and 15 girls) between 9 and 11 years old, who were studied with fMRI in two inhibitory attention tests (Go/No Go), with food cues, a working memory test (Continuous Performance Test Identical Pairs) and measurement of anatomical volumes. These data were subsequently processed with the FSL-v5 program, with a threshold of p < 0.05 (cluster-wise). The brain areas activated were located using a standard Montreal Neurological Institute brain template and the Harvard-Oxford structural cortical atlas. RESULTS: The inhibitory attention tests showed activation frontal areas predominantly on the right, and the cingulate, parietal and occipital areas, with preponderance in occipital areas in the food cues test. In the Continuous Performance Test-Identical Pairs test, activation was obtained predominantly in the occipital, frontal and parietal areas. CONCLUSIONS: Brain activity mapping templates are obtained in healthy children with tests for inhibitory attention, food cues and working memory. The activation areas are mostly those reported in the literature. This provides baseline brain activation patterns for studying pathologies related to inhibitory attention, impulsivity and working memory.

RESUMO

PURPOSE: To present the clinical, genetic, and histopathological features of the ninth family affected by congenital stromal corneal dystrophy (CSCD) to date. METHODS: Twelve cases of a Spanish family affected by CSCD were analyzed regarding history, visual acuity (VA, decimal scale), an ophthalmologic exam and specular microscopy. Five eyes were treated by deep anterior lamellar keratoplasty (DALK), and thirteen eyes by penetrating keratoplasty (PK). In the two last generations, a genetic study was performed. RESULTS: Most of the patients affected were born with opaque corneas except for three, whose corneas were clear at birth. Biomicroscopy showed a whitish diffuse stromal opacity with an unaltered epithelium, causing poor VA (from hand motions to 0.4). Patients treated with PK presented mean postoperative VA of 0.19±0.20 over a follow-up time of 235.3±101.4months with 38% recurrences. Patients who underwent DALK experienced VA improvement to 0.17±0.11 over a follow-up time of 10.8±2.6months without signs of recurrence. In the latter, the big bubble technique was not achieved, so a manual technique was performed. The genetic study showed heterozygosis for a 1-bp deletion at nucleotide 962 in exon 8 of the decorin gene. CONCLUSIONS: CSCD is a rare entity, which should be treated by DALK whenever possible, obtaining better results than PK. Close monitoring of children of affected individuals is important, because CSCD can progress during the early years of life.

RESUMO

BACKGROUND: The COVID-19 pandemic has posed an unprecedented challenge to healthcare systems globally. Personal protective equipment has played a fundamental role in protecting healthcare workers and patients, but its effectiveness in reducing hospital-acquired infections (HAIs) during the pandemic remains a subject of debate. AIM: To conduct a synthesis and meta-analysis of the best available evidence of the prevalence of HAIs using a before/after approach. METHODS: A three-step search strategy was undertaken to locate published and unpublished studies. A search was performed in MEDLINE, CINAHL, Embase, PsycINFO, and Google Scholar. Screening of studies, data extraction and critical appraisal were performed by four independent reviewers. Meta-analysis was conducted using Review Manager. The review is reported in accordance with PRISMA and JBI guidelines for systematic reviews. FINDINGS: Fifteen studies were included in the review. Three studies indicated a statistically significant increase in the number of positive cultures during the COVID-19 period compared to the pre-COVID-19 period. Pooled data showed a non-significant decrease in the number of patients with positive cultures in the COVID-19 period compared to pre-COVID-19. There were no significant differences in various bacterial infections except for a significant decrease in respiratory infections. Pooled data for central line-associated bloodstream infections (CLABSIs) indicated a significant increase during the COVID-19 period, but one study reported an increase in CLABSI incidence. CONCLUSION: The evidence from this review demonstrates a mixed impact of the COVID-19 pandemic precautions on HAIs.

RESUMO

Respiratory syncytial virus (RSV) is a major public health problem that has undergone significant changes in recent years. First of all, it has become easier to diagnose with highly reliable and rapidly available confirmatory tests. This has led to a better understanding of its epidemiology and RSV has gone from being a disease of the pediatric age group, severe only in infants and immunosuppressed children, to being a common disease in people of all ages, particularly important in patients of advanced age or with immunosuppressive diseases. Recent therapeutic and prophylactic advances, both with long-lasting monoclonal antibodies and vaccines, are another reason for satisfaction. For these reasons, the COVID and Emerging Pathogens Committee of the Illustrious Official College of Physicians of Madrid (ICOMEM) has considered it pertinent to review this subject in the light of new knowledge and new resources for dealing with this infection. We have formulated a series of questions that we believe will be of interest not only to members of the College but also to any non-expert in this subject, with a particular focus on the situation of RSV infection in Spain.

RESUMO

OBJECTIVES: To evaluate the predictive factors for biochemical failure and distant metastases in a prospective cohort of patients with localized prostate cancer treated with the combination of HDR BT and EBRT. METHODS AND MATERIALS: Patients with intermediate (IR) or high-risk (HR) prostate adenocarcinoma received a single fraction of HDR of 15 Gy combined with RT of 37.5 Gy in 15 fractions. ADT duration was used depending on risk-group. Descriptive analyses were performed. Univariate and multivariate Hazard Ratios were obtained. Finally, the Kaplan-Meier model was used to describe the survival of the events of interest. RESULTS: 309 patients were treated prospectively (199 were IR and 110 HR). Median age was 72 years; 58.3 % were MRI stage ≤ T2c, 34.1 % T3a and 7.6 % T3b; ISUP-grade 1-3 in 78.9 % and ISUP 4-5 in 21.1 %. 71.8 % of patients had ≤ 50 % positive-cores in biopsy and 28.2 % had > 50 %. Median pre-treatment PSA was 9.9 ng/mL. After a median follow-up of 88 months, 41 patients presented biochemical failure and 18 developed distant metastases. Multivariate cox-regression analyses found that MR-T3b Stage (HR 3.88, p = 0.001) and ADT use (HR 3.99, p = 0.03) were the only predictive factors for biochemical failure and the number of positive cores (>50 %) the only independent predictive factor of distant metastases (HR 4.36, p = 0.002). CONCLUSIONS: Patients with mpMRI evidence of invasion of the SV and involvement of more than 50% of the cores in the prostate biopsy are patients with a higher risk of presenting a biochemical recurrence or developing metastasis due to their prostate cancer, respectively.

RESUMO

Parsonage-Turner syndrome or idiopathic brachial neuritis is a total or partial inflammation of the brachial plexus, with a typical presentation as a sudden and very intense pain in the shoulder, followed by weakness and early amyotrophy. The etiology is still unknown, although an immune mediated mechanism is thought to be involved. Hematopoietic stem cell transplantation is a well-established treatment for hematological malignancies, but with a growing implication in the treatment of autoimmune diseases. The neurological side effects are probably underdiagnosed. The association of the Parsonage-Turner syndrome and the hematopoietic stem cell transplantation is scarce. We describe two clinical cases of idiopathic brachial plexopathy after hematopoietic stem cell transplantation. The reconstruction of the immune system after a transplant may be the trigger of a brachial plexopathy, but more studies are necessary for the etiology of this disease to be understood and to establish a cause-effect relation with the transplant.

RESUMO

INTRODUCTION: revision total knee arthroplasty (TKA) is a challenging procedure that requires proper alignment, restoration of bone loss, and prevention of instability. Modern revision systems offer progressive implant constriction with multiple options for offset, augmentation, and fixation stems. OBJECTIVE: to evaluate the clinical outcomes of a modular implant with hybrid fixation in revision TKA with a minimum follow-up of two years. MATERIAL AND METHODS: we retrospectively included all revision TKA surgeries performed between September 2018 and September 2019, using the same implant. Patient demographics, comorbidities, and data on bone defects were recorded. Clinical outcomes were assessed using subjective roles and Maudsley scores and the Knee Society Score (KSS). Complications during follow-up were also documented. RESULTS: a total of 23 patients were analyzed, comprising 65% females and 35% males, with a median age of 71.1 years. Bone defects following implant removal were classified as F2.T2 in 39.13% of cases, F1.T2 in 8.69%, and F1.T1 in the remaining 52.17%. There were significant improvements in the KSS score (preoperative: 53 points, postoperative: 79 points; p < 0.001). Three (13%) complications were reported, two of which were directly related to the surgery, and two patients required subsequent revision surgery. The 2-year survival rate was 91.3%. CONCLUSION: the use of a modular implant with hybrid fixation in revision TKA demonstrated a high 2-year survival rate, significant improvements in clinical scores, and a low incidence of short-term complications. These findings support the efficacy and safety of this approach, providing favorable clinical outcomes and high patient satisfaction.


INTRODUCCIÓN: la artroplastía total de rodilla (ATR) de revisión es un procedimiento desafiante que requiere alineación adecuada, restauración ósea y estabilidad. Los sistemas modernos de revisión ofrecen opciones de implantes modulares con fijación híbrida. OBJETIVO: evaluar los resultados clínicos de un implante modular de fijación híbrida con seguimiento mínimo de dos años. MATERIAL Y MÉTODOS: se incluyeron retrospectivamente cirugías de revisión de ATR realizadas entre Septiembre de 2018 y Septiembre de 2019 con el mismo implante. Se registraron datos demográficos, comorbilidades y se evaluaron los resultados clínicos utilizando puntuaciones subjetivas y la Knee Society Score (KSS). RESULTADOS: se analizaron 23 pacientes (65% mujeres, 35% hombres; edad mediana: 71.1 años). Los defectos óseos posteriores a la extracción del implante se clasificaron como F2.T2 en 39.13% de los casos, F1.T2 en 8.69%, y F1.T1 en 52.17%. Se observaron mejoras significativas en la puntuación de la KSS (preoperatoria: 53 puntos, postoperatoria: 79 puntos; p < 0.001). Se registraron tres (13%) complicaciones totales, dos relacionadas directamente con la cirugía, y dos casos requirieron una nueva cirugía de revisión. La tasa de supervivencia a los dos años fue de 91.3%. CONCLUSIÓN: el uso del implante modular con fijación híbrida en la revisión de ATR mostró una alta tasa de supervivencia a dos años, mejoras significativas en las puntuaciones clínicas y baja incidencia de complicaciones a corto plazo. Estos resultados respaldan la eficacia y seguridad de este enfoque, proporcionando resultados clínicos favorables y alta satisfacción del paciente.

RESUMO

During the East Antarctic International Ice Sheet Traverse (Eaiist, december 2019), in an unexplored part of the East Antarctic Plateau, snow samples were collected to expand our knowledge of the latitudinal variability of iodine, bromine and sodium as well as their relation in connection with emission processes and photochemical activation in this unexplored area. A total of 32 surface (0-5 cm) and 32 bulk (average of 1 m depth) samples were taken and analysed by Inductively Coupled Plasma Mass Spectrometry (ICP-MS). Our results show that there is no relevant latitudinal trend for bromine and sodium. For bromine they also show that it has no significant post-depositional mechanisms while its inland surface snow concentration is influenced by spring coastal bromine explosions. Iodine concentrations are several orders of magnitude lower than bromine and sodium and they show a decreasing trend in the surface samples concentration moving southward. This suggests that other processes affect its accumulation in surface snow, probably related to the radial reduction in the ozone layer moving towards central Antarctica. Even though all iodine, bromine and sodium present similar long-range transport from the dominant coastal Antarctic sources, the annual seasonal cycle of the ozone hole over Antarctica increases the amount of UV radiation (in the 280-320 nm range) reaching the surface, thereby affecting the surface snow photoactivation of iodine. A comparison between the bulk and surface samples supports the conclusion that iodine undergoes spring and summer snow recycling that increases its atmospheric lifetime, while it tends to accumulate during the winter months when photochemistry ceases.

RESUMO

Stressful events appear to be risky situations that can precipitate the consumption of drugs. One way to recreate stressful contexts, in an ecological and controlled method, is through immersive virtual reality (VR). In our study, we designed the scenario of an elevated plus-maze (EPM) using VR, which is widely used in animal models to assess unconditioned anxiety. This task allowed us to analyze the behavioral, psychophysiological (heart rate and electrodermal activity), and hormonal response (salivary cortisol and Alpha-amylase) to this stressful situation in different moments (before VR task (anticipation), at the end of the task and 10 minutes later) in young people with problematic alcohol use (AU, n = 27), alcohol combined with cannabis consumption (AU + C, n = 10), as well as in a control group (CO, n = 33). Behavioral analysis revealed that the AU group displayed fewer entries into open arms than the CO group, whereas both experimental groups spent less time at the end of the open arms, as well as lower time by look down index compared to the CO group. Moreover, our VR EPM induced different psychophysiological responses in the different moments measured. In general, electrodermal activity seemed to be a good biomarker of recovery from a stressful situation, as once the exposure to the stressful situation ended, the AU + C group took longer to recover compared to the CO group. Regarding hormonal analyses, we observed a similar response pattern in all groups suggesting that our VR task was able to activate both stress systems. The alpha-amylase to cortisol ratio, proposed as a biomarker of stress systems dysregulation, was higher in the group of young participants with alcohol abuse. Interestingly, our VR EPM was able to induce a slight alcohol craving in both experimental groups. In conclusion, our results suggest certain subtle behavioral and physiological differences that could be used to detect young individuals at risk of future severe addictions or other stress-related comorbidities. Moreover, it could help us to develop prevention strategies focused on emotional, cognitive, and psychophysiological aspects.

RESUMO

Anxious depression is a prevalent disease with devastating consequences. Despite the lack of knowledge about the neurobiological basis of this subtype of depression, recently our group has identified a relationship between the LPA1 receptor, one of the six characterized G protein-coupled receptors (LPA1-6) for lysophosphatidic acid, with a mixed depressive-anxiety phenotype. Dysfunctional social behaviors, which have been related to increased activation of the hypothalamus-pituitary-adrenal (HPA) axis, are key symptoms of depression and are even more prominent in patients with comorbid anxiety and depressive disorders. Social behavior and HPA functioning were assessed in animals lacking the LPA1 receptor. For these purposes, we first examined social behaviors in wild-type and LPA1 receptor-null mice. In addition, a dexamethasone (DEX) suppression test was carried out. maLPA1-null mice exhibited social avoidance, a blunted response to DEX administration and an impaired circadian rhythm of corticosterone levels, which are features that are consistently dysregulated in many mental illnesses including anxious depression. Here, we have strengthened the previous experimental evidence for maLPA1-null mice to represent a good animal model of anxious depression, providing an opportunity to explore new therapeutic targets for the treatment of mood disorders, particularly this subtype of depression.

RESUMO

The spatial distribution of five phthalate esters (PAEs) and 17 organochlorine compounds (OCs) in wild and raft mussels from Galician littoral collected in 2020, and its relationship with anthropogenic activities was studied in this work. The Rías de Foz and Muros-Noia were the most polluted by PAEs, while the Rías de Ferrol and Barqueiro by PCBs. The highest levels of all contaminants were present in wild mussel, except DEHP that were predominant in raft mussel. The levels of most PAEs were negatively correlated with levels of the lower chlorinated PCBs and OCPs. The spatial distribution of pollutants confirmed by PCA was affected by the proximity to anthropogenic sources, phthalates by urban wastewater and PCBs by industrial inputs, mainly. The study of human exposure assessment suggests that Risk Quotient values were < 1, so the consumption of Galician raft mussels did not pose a risk to human health.

RESUMO

Introducción: La miastenia gravis (MG) es una enfermedad autoinmune mediada por anticuerpos. El cuadro clínico se caracteriza por debilidad muscular fluctuante y fatigable, con frecuente afectación de músculos fonodeglutorios y respiratorios. Dada la severidad que implica el compromiso respiratorio en la MG, su evaluación rutinaria es esencial.Nuestro objetivo fue identificar un marcador semiológico útil en la pesquisa del compromiso respiratorio en pacientes con MG.Métodos: Se realizó un trabajo observacional en pacientes con diagnóstico de MG. Los pacientes fueron evaluados con test de cuenta máxima, pico flujo espiratorio (PEF), cuestionario de disnea modificado (mMRC) y valoración de fuerza del cuello. Los resultados de estos parámetros fueron correlacionados con la medición de CVF (capacidad vital forzada) y presiones bucales estáticas máximas (PiMáx y PeMáx). Resultados:Cuarenta y cinco pacientes con MG fueron incluidos, dos pacientes tenían MGFA grado I, 35 grado II, siete grado III y uno grado IV al momento de la evaluación. Se halló una correlación positiva entre el test de cuenta máxima y la CVF (r = 0,57, p = 0,000), y entre el PEF y la CVF (r = 0,76, p = 0,000). El grado de disnea, según el mMRC, mostró una correlación negativa con la CVF (r =-0,31 p = 0,03). A su vez, el PEF correlacionó con la PeMáx de forma positiva, estadísticamente significativa (r = 0,51, p = 0,002).Conclusiones: El PEF, el test de cuenta máxima y el mMRC fueron útiles para evaluar la función respiratoria en pacientes con MG.(AU)


Introduction: Myasthenia gravis (MG) is an antibody-mediated autoimmune disease characterised by fluctuating, fatigable muscle weakness, frequently involving bulbar and respiratorymuscles. Considering the severity of respiratory involvement in MG, routine evaluation ofrespiratory function is essential.The aim of this study was to identify a useful clinical marker of respiratory involvement inpatients with MG. Methods: We performed an observational study of patients with MG. All cases were evaluatedwith the single-breath counting test, peak expiratory flow (PEF), a modified Medical ResearchCouncil dyspnoea scale (mMRC), and a neck strength assessment. The results of these parameters were correlated with forced vital capacity (FVC), maximal inspiratory pressure (MIP), andmaximal expiratory pressure (MEP). Results: The study included 45 patients with MG: 2 patients classified as grade I on the Myasthenia Gravis Foundation of America classification at the time of evaluation, 35 classified asgrade II, 7 classified as grade III, and one classified as grade IV. Positive correlations were foundbetween single-breath counting test scores and FVC values (r = 0.57, p = .000), and betweenPEF and FVC values (r = 0.76, p = .000). Severity of dyspnoea according to the mMRC scaleshowed a negative correlation with FVC values (r = -0.31, p = .03). PEF also showed a significantcorrelation with MEP (r = 0.51, p = .002). Conclusions: PEF, the single-breath counting test, and the mMRC scale are useful measures forevaluating respiratory function in patients with MG.(AU)
