Introducción: Cuando la arteria cerebral posterior se origina desde la arteria carótida interna con un segmento P1 ausente, se denomina arteria cerebral posterior de origen fetal (ACPF). No está claro si la ACPF aumenta el riesgo de ictus isquémico agudo, y el tratamiento endovascular del ictus isquémico agudo debido a la oclusión aguda de la ACPF no está bien establecido. Caso clínico: Presentamos un caso de ictus isquémico agudo debido a la oclusión en tándem de la arteria carótida interna y la arteria cerebral posterior fetal ipsilateral tratado con éxito mediante la colocación de una endoprótesis en la lesión proximal y trombectomía mecánica de la lesión distal, con excelentes resultados neurológicos y funcionales. Conclusión: Aunque se necesitan más investigaciones para determinar el mejor tratamiento de estos pacientes, el tratamiento endovascular de la oclusión de la arteria cerebral posterior fetal es factible.(AU)

Introduction: When the posterior cerebral artery arises from the internal carotid artery with an absent P1 segment, it is called fetal posterior cerebral artery (FPCA). It is unclear whether FPCA increases the risk of acute ischemic stroke, and the endovascular treatment of acute ischemic stroke due to acute occlusion of FPCA is not well established. Case report: We report a case of acute ischemic stroke due to tandem occlusion of internal carotid artery and ipsilateral fetal posterior cerebral artery treated successfully with acute stenting of proximal lesion and mechanical thrombectomy of distal lesion with excellent neurological and functional outcomes. Conclusion: Although further investigations are needed to determine the best treatment of these patients, endovascular treatment of fetal posterior cerebral artery occlusion is feasible.(AU)

A modifiable factors-based model for detecting inactive individuals: are the European assessment tools fit for purpose?

BACKGROUND: The lack of systematic factors affecting physical inactivity (PIA) challenges policymakers to implement evidence-based solutions at a population level. The study utilizes the Eurobarometer to analyse PIA-modifiable variables. METHODS: Special Eurobarometer 412 physical activity (PA) data were analysed (n = 18 336), including 40 variables along with the International PA Questionnaire. PIA was used as the dependent variable. Variables considered were alternatives to car, places, reasons and barriers to engaging in PA, memberships to clubs and categorical responses about the agreement extent with the area, provision of activities and local governance statements. Logistic regression was used to identify variables contributing to PIA. Beta values (ß), standard errors, 95% confidence intervals, the exponentiation for odds ratio and Cox & Snell and Nagelkerke R2 were indicated. RESULTS: The resulting model correctly identified 10.7% inactives and 96.9% of actives (R2 of Nagelkerke: 0.153). Variables contributing to the detection of PIA were (P ≤ 0.01): having a disability or an illness, not having friends to do sport with, lacking motivation or interest in and being afraid of injury risk. Additionally, totally agreeing, tend to agree and tend to disagree regarding the extent of local providers offering enough opportunities to be more active also contributed to the model. CONCLUSIONS: The model reported a limited ability to detect modifiable factors affecting PIA, identifying a small percentage of inactive individuals correctly. New questions focused on understanding inactive behaviour are needed to support the European PA public health agenda.

Viability and characterization trial of a novel method as an alternative to formaldehyde and Walter-Thiel cadaveric preservation for medical education and surgical simulation / Viabilidad y prueba de caracterización de un nuevo método como alternativa al formaldehído y la solución de Walther-Thiel para la preservación de cadáveres para educación médica y simulación quirúrgica

Introduction Despite its toxic and carcinogenic nature, formaldehyde is a widely used reactant for specimen preservation. With the need of specimens for both anatomical and surgical training, alternative preservation solutions (PS) have been proposed, however, their use is limited due to high costs and complexity. Hence, a new formaldehyde-free solution (FFS) is evaluated as a potential alternative for anatomical and surgical training. Methods Qualitative and Quantitative data were acquired. Specimens preserved using three different methods were selected. Flexibility was measured by joints goniometry and pneumoperitoneum pressures were evaluated followed by an exploratory laparoscopy. Undergraduate student's perceptions on cadavers preserved with different PS were obtained using surveys and focus groups. Results The main reason why cadaveric specimens were considered as useful tools was the perceived interaction with real tissues and the ‘practical’ concept of getting in touch with what students would be facing in the future as physicians, what we call “hands on” activities. FFS treated specimens showed better joint-movement ranges in comparison to other methods and pneumoperitoneum was acquired after 5mmHg CO2 pressure. Students appreciated working with corpses regardless the technique used, however FFS specimens were defined as less uncomfortable, while presenting no sensory discomfort. Conclusions Even though alternative PS are effective, high costs and complexity restrict their usage. Cadavers preserved with FFS had similar range of movements compared with Thiel. Students preferred to work with FFS rather than FF due to flexibility, color, and no sensorial hassles. Thus, we propose FFS as viable alternative to traditional PS (AU)

Introducción A pesar de su naturaleza carcinogénica y tóxica, el formaldehido continúa siendo utilizado para preservar especímenes. Debido a la necesidad de especímenes para entrenamiento anatómico y quirúrgico, se han propuesto soluciones preservadoras (SP) alternativas; sin embargo, su uso es limitado debido a los altos costos y a su complejidad. En consecuencia, se evalúa una nueva solución libre de formol (FFS) como una alternativa para el uso en entrenamiento anatómico y quirúrgico. Métodos Se obtuvieron datos cualitativos y cuantitativos. Se seleccionaron especímenes preservados utilizando diferentes métodos y se analizaron biopsias de cada uno. Se midió la flexibilidad mediante goniometría, y se evaluó la presión del neumoperitoneo. Utilizando encuestas y grupos focales se obtuvo la percepción de estudiantes de pregrado respecto a cadáveres preservados con diferentes soluciones. Resultados Los principales motivos por los que los estudiantes refirieron percibir los cadáveres como herramientas útiles fueron poder interactuar con tejidos reales y el concepto de «practicidad» generado por actividades percibidas como similares a la práctica como médicos profesionales. Los especímenes tratados con FFS demostraron mejor movimiento articular en comparación con otras soluciones, además de lograr neumoperitoneo con 5mmHg de CO2. Los estudiantes refirieron sentir menos molestias sensoriales al utilizar cadáveres preservados con FFS. Conclusiones Aunque otras SP son efectivas, los altos costos y la complejidad restringen su uso. Cadáveres preservados con FFS presentan arcos de movimiento similares a Thiel. Los estudiantes prefirieron trabajar con FFS en vez de FF, debido a la flexibilidad, el color y la ausencia de molestias sensoriales. Proponemos FFS como una alternativa viable a las SP tradicionales (AU)

Brain potential responses involved in decision-making in weightlessness.

The brain is essential to human adaptation to any environment including space. We examined astronauts' brain function through their electrical EEG brain potential responses related to their decision of executing a docking task in the same virtual scenario in Weightlessness and on Earth before and after the space stay of 6 months duration. Astronauts exhibited a P300 component in which amplitude decreased during, and recovered after, their microgravity stay. This effect is discussed as a post-value-based decision-making closing mechanism; The P300 amplitude decrease in weightlessness is suggested as an emotional stimuli valence reweighting during which orbitofrontal BA10 would play a major role. Additionally, when differentiating the bad and the good docks on Earth and in Weightlessness and keeping in mind that astronauts were instantaneously informed through a visual cue of their good or bad performance, it was observed that the good dockings resulted in earlier voltage redistribution over the scalp (in the 150-250 ms period after the docking) than the bad dockings (in the 250-400 ms) in Weightlessness. These results suggest that in Weightlessness the knowledge of positive or negative valence events is processed differently than on Earth.

Percutaneous Trapeziometacarpal Arthrodesis in Thumb Carpometacarpal Joint Arthritis: A New Surgical Approach.

The high prevalence of trapeziometacarpal arthritis has resulted in the development of several surgical techniques intended to treat patients failing conservative treatment. However, there is no scientific evidence of the superiority of one technique over others. Open arthrodesis has up to now been successfully used to treat this condition. We believe that performing the technique using a minimally invasive approach with long and short Shannon burrs together with the tapered burr included in the MIS foot instrument set can yield satisfactory results. This article provides a description of this minimally invasive technique performed on a seventy-year-old woman with rhizarthrosis and an anatomical description of the approach in a human cadaver.

Spatiotemporal brain signal associated with high and low levels of proactive motor response inhibition.

Proactive motor response inhibition is used to strategically restrain actions in preparation for stopping. In this study, we first examined the event related potential (ERP) elicited by low and high level of proactive response inhibition, as assessed by the stop-signal task. Corroborating previous studies, we found an increased amplitude of the contingent negative variation (CNV) in the high level of proactive inhibition. As the main goal of the present study, swLORETA was used to determine the neural generators characterising CNV differences between low and high levels of proactive inhibition. Results showed that the higher level of proactive inhibition involved numerous generators, including within the middle and medial frontal gyrus. Importantly, we observed that the lower level of proactive inhibition also involved a specific neural generator, within the frontopolar cortex. Altogether, present findings identified the specific brain sources of ERP signals involved in the later phase of motor preparation under low or high levels of proactive motor response inhibition.

Minigammacámara portátil para el diagnóstico de muerte encefálica / Portable gamma-camera for the diagnosis of brain death diagnosis

Objetivo: Evaluar la factibilidad del empleo de la minigammacámara portátil Sentinella(R), para el diagnóstico de muerte encefálica (ME). Diseño: Estudio observacional, prospectivo, de factibilidad. Ámbito: Unidad de cuidados intensivos de un hospital de tercer nivel. Pacientes: Desde enero a diciembre de 2017 se registraron de forma consecutiva los pacientes mayores de edad que tras su ingreso en unidad de cuidados intensivos fueron diagnosticados de ME según criterios clínicos. Intervenciones: El procedimiento se realizó a la cabecera del paciente tras la administración intravenosa de tecnecio 99 metaestable-hexametil-propilen-amino-oxima. La ausencia de perfusión a nivel de hemisferios cerebrales y fosa posterior se describía como patrón compatible con ME. Se correlacionó el diagnóstico con doppler transcraneal y/o electroencefalograma. Resultados: Cincuenta y seis pacientes presentaron exploración física compatible con ME. Un 66,1% fueron hombres con una mediana de edad de 60 (RIQ: 51-72) años. La causa más frecuente que precipitó la ME fue el ictus hemorrágico en el 48,2% (27) seguido por traumatismo craneoencefálico grave en el 30,4% (17), ictus isquémico en el 10,7% (6) y encefalopatía anóxica tras parada cardiorrespiratoria en el 7,1% (4). En todos los casos se realizó el diagnóstico clínico de ME y posteriormente una gammagrafía portátil que confirmó dicho diagnóstico en el 100% de los pacientes. Se contrastó el resultado con doppler transcraneal en 46 de ellos que confirmaba la presencia de reverberación diastólica y/o picos sistólicos. En 10 casos se registró el electroencefalograma, con aparición de silencio eléctrico, debido a la ausencia de ventana acústica en el doppler transcraneal. Conclusiones: El uso de minigammacámara portátil puede resultar una herramienta útil y factible para el diagnóstico de ME

Objective: To evaluate the feasibility of using the Sentinella(R) portable gamma-camera for the diagnosis of brain death (BD). Design: A prospective, observational feasibility study was carried out. Setting: Intensive Care Unit of a third level hospital. Patients: Consecutive recording was made of the adults diagnosed with brain death based on clinical criteria following admission to the Intensive Care Unit in the period from January to December 2017. Interventions: The procedure was performed at the patient bedside with the intravenous administration of technetium 99 metastable hexamethylpropylene amine oxime. The absence of perfusion in the cerebral hemispheres and brainstem was described as a pattern consistent with BD. The diagnosis was correlated to the transcranial Doppler and / or electroencephalographic findings. Results: A total of 66.1% of the patients were men with an average age of 60 years [IQR: 51-72]. The most frequent causes resulting in BD were hemorrhagic stroke (48.2%, n=27), followed by traumatic brain injury (30.4%, n=17), ischemic stroke (10.7%, n=6) and post-cardiac arrest anoxic encephalopathy (7.1%, n=4). A clinical diagnosis of BD was made in all cases, and the portable gamma-camera confirmed the diagnosis in 100% of the patients with a pattern characterized by the absence of brain perfusion. In addition, the results were compared with the transcranial Doppler findings in 46 patients, confirming the presence of diastolic reverberation and / or systolic peaks. The electroencephalographic tracing was obtained in 10 cases, with the appearance of electrical silence, due to the absence of an acoustic window in the transcranial Doppler study. Conclusions: A portable gamma-camera could be a useful and feasible tool for the diagnosis of BD

The active living gender's gap challenge: 2013-2017 Eurobarometers physical inactivity data show constant higher prevalence in women with no progress towards global reduction goals.

BACKGROUND: The World Health Organization (WHO) considers physical inactivity (PIA) as a critical noncommunicable factor for disease and mortality, affecting more women than men. In 2013, the WHO set a 10% reduction of the PIA prevalence, with the goal to be reached by 2025. Changes in the 2013-2017 period of physical inactivity prevalence in the 28 European Union (EU) countries were evaluated to track the progress in achieving WHO 2025 target. METHODS: In 2013 and 2017 EU Special Eurobarometers, the physical activity levels reported by the International Physical Activity Questionnaire of 53,607 adults were analyzed. Data were considered as a whole sample and country-by-country. A χ2 test was used to analyze the physical inactivity prevalence (%) between countries, analyzing women and men together and separately. Additionally, PIA prevalence was analyzed between years (2013-2017) for the overall EU sample and within-country using a Z-Score for two population proportions. RESULTS: The PIA prevalence increased between 2013 and 2017 for the overall EU sample (p <  0.001), and for women (p = 0.04) and men (p < 0.001) separately. Data showed a higher PIA prevalence in women versus men during both years (p <  0.001). When separately considering changes in PIA by gender, only Belgium's women and Luxembourg's men showed a reduction in PIA prevalence. Increases in PIA prevalence over time were observed in women from Austria, Croatia, Germany, Lithuania, Malta, Portugal, Romania, and Slovakia and in men from Bulgaria, Croatia, Czechia, Germany, Italy, Lithuania, Portugal, Romania, Slovakia, and Spain. CONCLUSIONS: PIA prevalence showed an overall increase across the EU and for both women and men between 2013 and 2017, with higher rates of PIA reported for women versus men during both years. PIA prevalence was reduced in only Belgium's women and Luxembourg's men. Our data indicate a limited gender-sensible approach while tacking PIA prevalence with no progress reaching global voluntary reductions of PIA for 2025.

Effect of a multi-ingredient based food supplement on sexual function in women with low sexual desire.

BACKGROUND: Studies have demonstrated that women with low desire and low excitement have negative feelings regarding their physical and emotional satisfaction, as well as their happiness. In this study, we evaluate the efficacy of Libicare® - a multi-ingredient food supplement - to improve sexual function in postmenopausal women. METHODS: This was an exploratory, prospective, non-controlled, observational study. Postmenopausal women aged 45-65 with a risk of sexual dysfunction (Female Sexual Function Index (FSFI) < 25.83) were included during routine clinical visits and treated with 2 tablets of Libicare® daily for 2 months. Libicare® is an oral food supplement containing Trigonella foenum graecum, Turnera diffusa, Tribulus terrestris, and Ginkgo biloba dry extracts. Primary endpoint: change vs. baseline in FSFI score. Secondary endpoints: 1) changes in testosterone and serum steroid levels of free testosterone and sex hormone-binding globulin (SHBG) levels and 2) tolerability. RESULTS: A total of 29 patients (mean age: 54.69 years) were included. FSFI mean (SD) score showed a significant increase: 20.15 (4.48) vs 25.03 (6.94), baseline vs final; p = 0.0011, paired t-test. Most patients (86.2%) increased their FSFI score. All FSFI domains, except dyspareunia, showed significant increases. The highest increase was observed in the desire domain (p = 0.0004). Testosterone and SHBG levels were assessed in 21 patients. A significant increase in testosterone level was observed: 0.41 (0.26) vs. 0.50 (0.34) pg/mL, baseline vs. final; p = 0.038, Wilcoxon test. 52.4% of patients increased their testosterone levels. Finally, a significant decrease was observed in SHBG level: 85 (32.9) vs. 73 (26.8) nmol/L, baseline vs. final; p = 0.0001; paired t-test. 95.2% of patients decreased their SHBG levels. CONCLUSION: In this pilot study, a significant improvement in sexual function and related hormone levels was observed with Libicare®. Further studies must be conducted to confirm these exciting results. TRIAL REGISTRATION: Current Controlled Trial ISRCTN12928573 . Date of registration: 28/March/2019. Retrospectively registered.

A retrospective analysis of policy development on compliance with World Health Organization's physical activity recommendations between 2002 and 2005 in European Union adults: closing the gap between research and policy.

BACKGROUND: Physical inactivity (PIA) is a mortality risk factor defined as performing lower levels of physical activity than recommended by the World Health Organization (WHO). After 2002, the WHO released the WHA55.23 Resolution and the Global Strategy which produced several changes in policymaking, but with no subsequent analyses of the impact of these changes in European Union (EU) policymaking while examining PIA prevalence. METHODS: PIA of 31,946 adults as a whole sample and country-by-country were analyzed in the 2002 and 2005 EU Special Eurobarometers. PIA prevalence between countries was performed with the χ2 test and PIA between both years and between genders was analyzed with the Z-Score test for two population proportions. A retrospective analysis of national plans was performed to interpret the suitability of such policy documents, considering changes in PIA prevalence. RESULTS: Differences in PIA prevalence were observed between countries (p <  0.001) and years (p <  0.001) for the whole sample and men and women separately. Within-country samples showed no differences for Denmark, Finland, Ireland, Italy, Luxemburg, Portugal, and Spain (p > 0.05). When considering gender, there were no gender reductions in subsamples for Denmark, Finland, Ireland, Portugal, Spain, and United Kingdom, neither in Luxemburg for men, nor in France and Italy for women. When analyzing gender differences across the entire sample, PIA was higher in women than men for both years (p <  0.001). Greece and Luxemburg did not release national plans for promoting physical activity. CONCLUSIONS: While large differences in PIA prevalence between EU countries prevailed, the overall PIA descended between both years for the whole sample, men, and women. While this points out a general suitability of policymaking for reducing PIA, not all countries reported reductions in PIA for men, women, or both genders. Also, PIA levels were higher for women in both years, suggesting a less than optimal policy implementation, or lack of women-specific focus across the EU. This analysis helps to identify the strengths and weaknesses of PIA policymaking in the EU and provides researchers with targeted intervention areas for future development.

EEG Dynamics and Neural Generators in Implicit Navigational Image Processing in Adults with ADHD.

In contrast to childhood ADHD that is characterized by inattention, impulsivity and hyperactivity, most adults with ADHD predominantly exhibit inattention. We used a new oddball paradigm using implicit navigational images and analyzed EEG dynamics with swLORETA inverse modeling of the evoked potential generators to study cortical processing in adults with ADHD and age-matched controls. In passive observation, we demonstrated that P350 amplitude, alpha-beta oscillation event-related synchronization (ERS) anticipation, and beta event-related desynchronization (ERD) were significantly smaller in ADHD. In the active condition, P100 duration was reduced and N140 amplitude increased for both deviant and frequent conditions in the ADHD. Alpha ERS and delta-theta ERS were reduced in the ADHD in the deviant condition. The left somatosensory area (BA2) and the right parietal lobe (BA31, BA40) contributed more to the P100 generators in the control than in the ADHD group, while the left frontal lobe (BA10) contributed more to the P100 generators in the ADHD. The left inferior parietal lobe (BA40) contributed more to the N140 generators in the control than the ADHD group while the right posterior cingulate (BA30) contributed more to the N140 generators in the ADHD. These findings reinforce the notion that earlier cortical stages of visual processing are compromised in adult ADHD by inducing the emergence of different even-related potential generators and EEG dynamics in ADHD. Considering that classical approaches for ADHD diagnosis are based on qualitative clinical investigation possibly biased by subjectivity, EEG analysis is another objective tool that might contribute to diagnosis, future neurofeedback or brain stimulation therapies.
