RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

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.

RESUMEN

INTRODUCTION: A prospective stroke registry leads to improved knowledge of the disease. We present data on the Mataró Hospital Registry. METHODS: In February-2002 a prospective stroke registry was initiated in our hospital. It includes sociodemographic data, previous diseases, clinical, topographic, etiological and prognostic data. We have analyzed the results of the first 10 years. RESULTS: A total of 2,165 patients have been included, 54.1% male, mean age 73 years. The most frequent vascular risk factor was hypertension (65.4%). Median NIHSS on admission: 3 (interquartile range, 1-8). Stroke subtype: 79.7% ischemic strokes, 10.9% hemorrhagic, and 9.4% TIA. Among ischemic strokes, the etiology was cardioembolic in 26.5%, large-vessel disease in 23.7%, and small-vessel in 22.9%. The most frequent topography of hemorrhages was lobar (47.4%), and 54.8% were attributed to hypertension. The median hospital stay was 8 days. At discharge, 60.7% of patients were able to return directly to their own home, and 52.7% were independent for their daily life activities. After 3 months these percentages were 76.9% and 62.9%, respectively. Hospital mortality was 6.5%, and after 3 months 10.9%. CONCLUSIONS: Our patient's profile is similar to those of other series, although the severity of strokes was slightly lower. Length of hospital stay, short-term and medium term disability, and mortality rates are good, if we compare them with other series.

RESUMEN

BACKGROUND: Risk of stroke soon after a transient ischaemic attack (TIA) is high. Urgent care can reduce this risk. Our aim is to describe and evaluate the efficacy of rapid assessment of TIA patients in a hospital without a neurologist available 24 hours a day. METHODS: In February 2007, we set up a protocol of rapid management of patients with symptoms consistent with acute TIA, with the aim of prioritising urgent care and reducing hospital admissions, without increasing risk of recurrences. We analyse our results since the protocol was implemented with particular focus on the analysis of delay in neurological and neurovascular assessment, percentage and reasons for hospitalisation, and stroke recurrence rates after 3 months. RESULTS: Four hundred and eleven patients were studied, with a final diagnosis of TIA in 282 (68.6%). Among other diagnoses, the most frequent were a vasovagal reaction (5.6%) and confusional syndrome (4.6%). Delay between emergency arrival and neurovascular assessment was <24h in 82% of the cases, and <48 h in 93%. After neurological evaluation, 28.7% of the patients were immediately admitted to hospital (most common causes: severe stenosis of a large artery and crescendo TIA). The incidence of ischaemic stroke in TIA patients was 3.55% after 3 months and 70% of them suffered the recurrence within the first week after the initial TIA. CONCLUSIONS: In a hospital without a neurologist available 24 hours a day, early assessment and management of TIA patients can be carried out in accordance with the guidelines, and may avoid hospitalisation in most cases without increasing recurrence rates.

RESUMEN

The N30 component of the somatosensory evoked potential is known to be modulated by sensory interference, motor action, movement ideation and observation. We introduce a new paradigm in which the observation task of another person's hand movement triggers the somatosensory stimulus, inducing the N30 response in participants. In order to identify the possible contribution of the mirror neuron network (MNN) to this early sensorimotor processing, we analyzed the N30 topography, the event-related spectral perturbation and the inter-trial coherence on single electroencephalogram (EEG) trials, and we applied swLORETA to localize the N30 sources implicated in the time-frequency domain at rest and during observation, as well as the generators differentiating these two contextual brain states. We found that N30 amplitude increase correlated with increased contralateral precentral alpha, frontal beta, and contralateral frontal gamma power spectrum, and with central and precentral alpha and parietal beta phase-locking of ongoing EEG signals. We demonstrate specific activation of the contralateral post-central and parietal cortex where the angular gyrus (BA39), an important MNN node, is implicated in this enhancement during observation. We conclude that this part of the MNN, involved in proprioceptive processing and more complex body-action representations, is already active prior to somatosensory input and may enhance N30.

RESUMEN

BACKGROUND: Pre-eruptive intracoronal resorption is a dental lesion located within the dentin. This defect is usually discovered incidentally on routine dental radiographs. Occasionally this process may be associated with oral pain in advanced lesions. CASE REPORT: This case report describes a 12-year-old boy whose chief complaint was a diffuse oral pain due to a severe pre-eruptive intracoronal resorption in a permanent second molar. The previous radiographs, taken at the age of nine years, showed no evidence of the lesion. After surgical exposure, a pulp-like tissue under the crown was removed and analyzed; subsequently the tooth was extracted due to extensive resorption. A follow-up of the unerupted third molar, still in formation process, allowed to see that it was favourably positioned for replacing the extracted molar.

RESUMEN

OBJECTIVES: Undiagnosed abnormal glucose metabolism is often seen in patients admitted with acute myocardial infarction, although there is no consensus on which patients should be studied with a view to establishing an early diagnosis. The present study examines the potential of certain variables obtained upon admission to diagnose abnormal glucose metabolism. DESIGN: A prospective cohort study was carried out. SETTING: The Intensive Care Unit of Arrixaca University Hospital (Murcia), Spain. PATIENTS: A total of 138 patients admitted to the Intensive Care Unit with acute myocardial infarction and without known or de novo diabetes mellitus. After one year, oral glucose tolerance testing was performed. MAIN OUTCOMES: Clinical and laboratory test parameters were recorded upon admission and one year after discharge. Additionally, after one year, oral glucose tolerance tests were made, and a study was made of the capacity of the variables obtained at admission to diagnose diabetes, based on the ROC curves and multivariate analysis. RESULTS: Of the 138 patients, 112 (72.5%) had glucose metabolic alteration, including 16.7% with diabetes. HbA1c was independently associated with a diagnosis of diabetes (RR: 7.28, 95%CI 1.65 to 32.05, P = .009), and showed the largest area under the ROC curve for diabetes (0.81, 95%CI 0.69 to 0.92, P = .001). CONCLUSIONS: In patients with acute myocardial infarction, HbA1c helps identify those individuals with abnormal glucose metabolism after one year. Thus, its determination in this group of patients could be used to identify those subjects requiring a more exhaustive study in order to establish an early diagnosis.

RESUMEN

OBJECTIVES: To determine whether there is a linear association of age and aspirin, betablockers, angiotensin-converting enzyme inhibitors and statins; the extent to which elderly patients receive these treatments; and whether age is independently associated with these treatments. DESIGN: A prospective cohort study. SETTING: Coronary Unit of two hospitals in the Region of Murcia (Spain). PATIENTS: Consecutive patients admitted with the diagnosis of acute myocardial infarction between January 1998 and January 2008. INTERVENTIONS: None. MAIN OUTCOMES: Those related to the administration of aspirin, betablockers, angiotensin-converting enzyme inhibitors and statins during stay in the Coronary Care Unit. RESULTS: Regarding the remaining patients, octogenarians received a similar proportion of angiotensin-converting enzyme inhibitors (70.8% vs. 69.3%, p=0.41) and less often aspirin (90.4% vs. 94.6%, p<0.001), betablockers (44.4% vs. 69.4%, p<0,001) and statins (47.6% vs. 64.7%, p<0.001). We were only able to demonstrate an abrupt and significant decrease in the use of statins after 80 years of age. Patient age was independently associated with the use of betablockers (OR 0.59; 95%CI 0.47 - 0.73) and statins (OR 0.78; 95%CI 0.65 - 0.95). The lesser administration of these drugs was also associated with early mortality (OR 0.17, 95%CI 0.09 to 0.33 and OR 0.14; 95%CI 0.08 to 0.23, respectively). CONCLUSIONS: Octogenarians less often receive aspirin, betablockers and statins, though old age was not an independent factor associated with lesser aspirin use.

RESUMEN

Linear immunoglobulin (Ig) A dermatosis is an immune-mediated bullous disease characterized by linear deposits of IgA along the basal membrane. While usually idiopathic, it can occasionally be induced by drug exposure. We report the case of a 60-year-old woman with rheumatoid arthritis being treated with sulfasalazine who developed linear IgA dermatosis and drug rash with eosinophilia and systemic symptoms (DRESS). The dermatosis and associated symptoms resolved following withdrawal of the drug and treatment with systemic corticosteroids for 2 months. This is the first report of sulfasalazine-induced linear IgA dermatosis in association with DRESS and we believe that sulfasalazine should be added to the list of drugs that can cause linear IgA dermatosis.

RESUMEN

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.


TITLE: Ictus isquémico agudo por oclusión en tándem de la arteria carótida interna y la arteria cerebral posterior fetal: tratamiento endovascular.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.

RESUMEN

Acute disseminated encephalomyelitis is an immune mediated inflammatory-demyelinizing disease that usually manifests after infection or vaccination in school-age children. It typically presents a prodromal phase with flu-like symptoms, followed by a phase with varied clinical symptoms, neuro-ophthalmological alterations such as ophthalmoplegia or optic neuritis may occur. The differential diagnosis includes tumor, vascular, infectious, inflammatory and demyelinating diseases. Diagnosis is based on the clinical history and the characteristics of brain magnetic resonance imaging, the gold standard test. The study of the cerebrospinal fluid can help to guide the clinical picture. The prognosis is favorable, with an excellent response to corticosteroids and immunoglobulins, with minimal long-term sequelae in most cases. We report the case of an 8-year-old male with acute demyelinating disease due to adenovirus whose manifestation was an eight-and-a-half syndrome.

RESUMEN

The purpose of this study was to compare acute mechanical and metabolic effects of 2 sessions of resistance training equated by volume and total resting time but with different set configuration: sets to failure (FS) vs. distribution of rest between each repetition (NFS). 10 male judoists completed a session consisting of 3 sets to failure of parallel back squat with 4 repetitions at maximum load, and a rest of 3 min between the sets. At least 72 h later subjects developed the same volume, but total resting time was distributed among individual repetitions. Before and after sessions isometric force and mean propulsive velocity with load corresponding to maximum propulsive power were assessed. Results showed that in respect to FS, NFS showed an 18.94% (± 17.98) higher average mean propulsive velocity during session (0.42 ± 0.04 vs. 0.35 ± 0.08 m.s - 1; p=0.009), lower blood lactate concentration after session (maximum average value 1.52 ± 0.77 vs. 3.95 ± 1.82; session effect: p=0.001) and higher mean propulsive velocity with load corresponding to maximum propulsive power (mean propulsive velocity immediately after session 0.64 ± 0.09 vs. 0.59 ± 0.12 m.s - 1; session effect: p=0.019). These data show that distribution of rest in sessions equated for volume and total resting time determines differences in performance during sessions and mechanical or metabolic acute effects.

RESUMEN

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.

RESUMEN

The N30 component of somatosensory evoked potentials has been recognized as a crucial index of brain sensorimotor processing and has been increasingly used clinically. Previously, we have shown that the N30 is accompanied by both an increase of the power spectrum of the ongoing beta-gamma EEG (event related synchronization, ERS) and by a reorganization (phase-locking) of the spontaneous phase of this rhythm (inter-trials coherency, ITC). In order to localize its sources taking into account both the phasic and oscillatory aspects of the phenomenon, we here apply swLORETA methods on averaged signals of the event-related potential (ERP) from a 128 scalp-electrodes array in time domain and also on raw EEG signals in frequency domain at the N30 peak latency. We demonstrate that the two different mechanisms that generate the N30 component power increase (ERS) and phase locking (ITC) across EEG trials are spatially localized in overlapping areas in the precentral cortex, namely the motor cortex (BA4) and the premotor cortex (BA6). From this common region, the generator of the N30 event-related potential expands toward the posterior part of BA4, the anterior part of BA6 and the prefrontal cortex (BA9). These latter areas also present significant ITC sources in the beta-gamma frequency range, but without significant power increase of this rhythm. This demonstrates that N30 results from network activity that depends on distinct oscillating and phasic generators localized in the frontal cortex.

RESUMEN

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.

RESUMEN

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.

RESUMEN

OBJECTIVE: To evaluate the feasibility of using the Sentinella® 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.
