RESUMEN

Mammalian life history strategies can be characterised by a few axes of variation, conforming a space where species are positioned based on the life history strategies favoured in the environment they exploit. Yet, we still lack global descriptions of the diversity of realised mammalian life history and how this diversity is shaped by the environment. We used six life history traits to build a life history space covering worldwide mammalian adaptation, and we explored how environmental realms (land, air, water) influence mammalian life history strategies. We demonstrate that realms are tightly linked to distinct life history strategies. Aquatic and aerial species predominantly adhere to slower life history strategies, while terrestrial species exhibit faster life histories. Highly encephalised terrestrial species are a notable exception to these patterns. Furthermore, we show that different mode of life may play a significant role in expanding the set of strategies exploitable in the terrestrial realm. Additionally, species transitioning between terrestrial and aquatic realms, such as seals, exhibit intermediate life history strategies. Our results provide compelling evidence of the link between environmental realms and the life history diversity of mammals, highlighting the importance of differences in mode of life to expand life history diversity.

RESUMEN

BACKGROUND: Prognostic factors of long-term survival can guide selection of patients for endovascular repair of abdominal aortic aneurysms (EVAR). The aim of this study was to evaluate the relationship between the neutrophil-to-lymphocyte ratio (NLR), the platelet-to-lymphocyte ratio (PLR), the lymphocyte-to-monocyte ratio (LMR) and the systemic immune-inflammation index (SIII) with survival after EVAR and to assess whether the addition of these biomarkers improved the prediction of survival after surgery. METHODS: Retrospective analysis of 284 consecutive patients who underwent an EVAR at a single institution. The association between biomarkers and survival was explored using generalized additive models with penalized smoothing splines and multivariate Cox models. C-statistics and continuous net reclassification indexes (c-NRI) were used to assess the improvement in prediction. RESULTS: Survival rates at 2 and 5 years were 83.9% and 66.2%, respectively. The predictive score of survival included hemoglobin (HR = 0.849, p = 0.004), statin intake (HR = 0.538, p = 0.004), atrial fibrillation (HR = 2.515, p < 0.001), heart failure (HR = 2.542, p = 0.017) and the non-revascularized coronary artery disease (HR = 2.163, p = 0.004). Spline analyses showed a linear relationship between survival and NLR, PLR, LMR and SII. After adjusting for the predictive score, there was an independent relationship between survival and NLR (HR = 1.072, p = 0.006), PLR (HR = 1.002, p = 0.014) and SII (HR = 1.000, p = 0.043). However, only the addition of NLR improved moderately the c-NRI. A NLR ≥ 3 was independently associated with lower survival rates at 2-years (HR 1.98; 95% CI 1.07-3.66) and 5-years (HR 1.84, 95% CI 1.22-2.78) of follow-up. CONCLUSIONS: Most inflammatory biomarkers are linear and independently associated with survival after EVAR, but only the NLR improved moderately the prediction of a survival score. Therefore, a NLR ≥ 3 may be used to identify patients with a low survival rate and help in decision-making.

RESUMEN

The National Institute for Health and Care Excellence (NICE) has recently updated the guideline for Acute kidney injury: prevention, detection and management (NG148), providing new recommendations on preventing acute kidney injury (AKI) in adults receiving intravenous iodine-based contrast media. The association between intravenous iodinated contrast media and AKI is controversial, particularly with widespread use of iso-osmolar agents. Associations between contrast media administration and AKI are largely based on observational studies, with inherent heterogeneity in patient populations, definitions applied, and timing of laboratory investigations. In an attempt to mitigate risk, kidney protection has typically been employed using intravenous volume expansion and/or oral acetylcysteine. Such interventions are in widespread use, despite lacking high-quality evidence of benefit. In the non-emergency setting, glomerular filtration rate (GFR) measurements should be obtained within the preceding 3 months before offering intravenous iodine-based contrast media. In the acute setting, adults should also have their risk of AKI assessed before offering intravenous iodine-based contrast media; however, this should not delay emergency imaging. Based on the evidence available from randomised controlled trials, the NICE committee recommends that oral hydration should be encouraged in adults at increased risk of AKI and that volume expansion with intravenous V fluids should only be considered for inpatients at particularly high risk.

RESUMEN

OBJECTIVE: To describe the pharmacological management of borderline personality disorder (BPD) in Spain from 2001 through 2016, the factors associated with prescriptions, and changes in pharmacotherapy over this time period. METHODS: Retrospective, cross-sectional, observational study conducted in a sample of 457 patients with BPD consecutively admitted to a specialist BPD Program between January 2001 and November 2016. Data on sociodemographic and clinical variables, as well as pharmacological treatment upon the admission to the programme, were used to describe pharmacological prescriptions, the factors associated with these medications, and changes in prescription over the last 15 years. RESULTS: Most (88.4%) patients were on pharmacological treatment, with 53.8% of persons taking ≥3 medications. No significant changes in these percentages were observed over the study period. The use of tricyclic antidepressants and benzodiazepines decreased, while the use of atypical antipsychotics increased. Axis I comorbidity was the main factor associated with pharmacological treatment and polypharmacy. CONCLUSIONS: This study provides further evidence confirming the worldwide overuse of prescription medications for BPD and shows that there has been a shift in the prescription pattern in the last 15 years. These results suggest that real clinical practice only partially adheres to clinical treatment guidelines.

RESUMEN

Fasciolosis caused by Fasciola hepatica severely affects the efficiency of livestock production systems worldwide. In addition to the economic impact inflicted on livestock farmers, fasciolosis is an emergent zoonosis. This review emphasizes different aspects of the disease in South America. Available data on epidemiology in bovines and ovines in different countries, as well as a growing body of information on other domestic and wildlife definitive hosts, are summarized. The issue of drug resistance that compromises the long-term sustainability of current pharmacological strategies is examined from a regional perspective. Finally, efforts to develop a single-antigen recombinant vaccine in ruminants are reviewed, focusing on the cases of leucine aminopeptidase or thioredoxin glutathione reductase.

RESUMEN

BACKGROUND: The presence of liver fibrosis is the common denominator in numerous chronic liver diseases that can progress to fibrosis and hepatocellular carcinoma. Most important, with respect to frequency, are viral hepatitis and non-alcoholic fatty liver disease, the prevalence of which is increasing in epidemic proportions. Liver biopsy, albeit imperfect, continues to be the criterion standard, but in many clinical situations tends to be replaced with noninvasive imaging methods. OBJECTIVES: The aim of the present article was to describe our imaging department experience with magnetic resonance elastography and to analyze and discuss recently published results in gastroenterology, hepatology, and radiology from other authors in the literature, complemented with a PubMed search covering the last 10 years. RESULTS AND CONCLUSIONS: Magnetic resonance elastography is an efficacious, noninvasive method with results that are concordant with liver biopsy. It is superior to ultrasound elastography because it evaluates a much greater volume of hepatic tissue and shows the often heterogeneous lesion distribution. The greatest advantage of the magnetic resonance protocol described is the fact that it quantifies fibrosis, fat content, and iron content in the same 25min examination specifically directed for that purpose, resulting in a favorable cost-benefit ratio for the patient and/or institution.

RESUMEN

The aim of this study was to investigate the epidemiology and transmission of Taenia hydatigena in sheep and dogs from Sardinia and the economic estimation of losses due to this metacestodosis in lambs. A total of 7781 Sarda breed lambs were examined at abattoirs for the detection of Cysticercus tenuicollis or necrotic-haemorrhagic tracks of their migration. Morphological and molecular identification of parasites was carried out. Individual faecal samples from 300 dogs were examined for copromicroscopic investigations and coproELISA assay. An overall prevalence of 14.6% for T. hydatigena cysticercosis was found in the examined lambs. In total, 10,807 parasitary tracks were found, with an abundance of 1.39 and an average intensity of 9.52. The molecular analysis of the isolates showed an overall pairwise nucleotide divergence for the CO1 and ND1 was of 0-3.1 and 0-3.3%, respectively. Low intra- and interspecific variation was recorded for C. tenuicollis isolates used in this study which suggested the absence of differentiation. Microscopic examination of dog faeces showed a total prevalence of 31.3% for endoparasites in the examined samples (94/300). Taeniid eggs were found in 8.3% of the dogs. The results of the monoclonal antibody ATH4 ELISA test showed a prevalence of 11% (33/300) for T. hydatigena coproantigens. The total economic costs related to cysticercosis amounted to almost € 330,000. The prevalence of C. tenuicollis in 14.6% of 30-40-day-old lambs highlights the high parasitic pressure by T. hydatigena in the territory of Sardinia, Italy.

RESUMEN

Gadolinium-enhanced magnetic resonance for the evaluation of hepatic lesions is increasingly being used in clinical practice, especially in patients with suspicious focal lesions, whether benign or malignant. In regard to hepatocellular carcinoma, the diagnostic performance of magnetic resonance through the «conventional¼ protocols and multi-detector computerized tomography consisting of multiphase evaluation with intravenous contrast, largely depends on the size of the lesion. They are more reliable in lesions>2cm. However, in lesions measuring 1-2cm, establishing the definitive diagnosis is a real challenge, with sensitivity values of 45-65%, but generally with excellent specificity (>95%). Furthermore, if the lesion has a diameter<1cm, diagnosis is usually unreliable. In these last 2 settings, the complementary use of liver-specific contrast agents can be advantageous. The aim of our article was to review the current evidence on the usefulness of this new non-invasive diagnostic method in hepatic lesions.

RESUMEN

The Anthropocene is tightly associated with a drastic loss of species worldwide and the disappearance of their key ecosystem functions. The orders Testudines (turtles and tortoises) and Crocodilia (crocodiles, alligators, and gharials) contain numerous threatened, long-lived species for which the functional diversity and potential erosion by anthropogenic impacts remains unknown. Here, we examine 259 (69%) of the existing 375 species of Testudines and Crocodilia, quantifying their life history strategies (i.e., trade-offs in survival, development, and reproduction) from open-access data on demography, ancestry, and threats. We find that the loss of functional diversity in simulated extinction scenarios of threatened species is greater than expected by chance. Moreover, the effects of unsustainable local consumption, diseases, and pollution are associated with life history strategies. In contrast, climate change, habitat disturbance, and global trade affect species independent of their life history strategy. Importantly, the loss of functional diversity for threatened species by habitat degradation is twice that for all other threats. Our findings highlight the importance of conservation programmes focused on preserving the functional diversity of life history strategies jointly with the phylogenetic representativity of these highly threatened groups.

RESUMEN

STUDY OBJECTIVE: There is very limited information about the effect of continuous positive airway pressure (CPAP) in the very elderly. Here we aimed to analysed the effect of CPAP on a clinical cohort of patients with obstructive sleep apnea (OSA) ≥80 years old. METHODS: Post-hoc pooled analysis of two open-label, multicenter clinical trials aimed to determine the effect of CPAP in a consecutive clinical cohort of elderly (≥70 years old) with moderate-to-severe OSA (apnea-hipopnea index ≥15 events/hour) randomized to receive CPAP or no CPAP for three months. Those consecutive patients ≥80 years old were included in the study. The primary endpoint was the change in Epworth Sleepiness scale (ESS). Secondary outcomes included sleep-related symptoms, quality of life, neurocognitive and mood status as well as office blood pressure measurements. RESULTS: From the initial 369 randomized individuals with ≥70 years, 97 (26.3%) with ≥80 years old were included (47 in the CPAP group and 50 in the no-CPAP group). The mean (SD) age was 81.5 (2.4) years. Average use of CPAP was 4.3 (2.6) hours/night (53% with good adherence) Patients in the CPAP group significantly improved snoring and witnessed apneas as well as AHI (from 41.9 to 4.9 events/hour). However no clinical improvements were seen in ESS (-1.2 points, 95%CI, 0.2 to -2.6), any domain of QSQ, any neurocognitive test, OSA-related symptoms, depression/anxiety or blood pressure levels. CONCLUSIONS: The present study does not support the use of CPAP in very elderly patients with moderate-to-severe OSA.

RESUMEN

Experiments on hybridization between Fasciola hepatica and Fasciola gigantica were carried out to clarify whether a reproductive isolating mechanism appears between the two Fasciola species. Molecular evidence for hybridization was based on the DNA sequence of the internal transcribed spacer 1 (ITS1) region in nuclear ribosomal DNA, which differs between the species. The results suggested that there were not pre-mating but post-mating isolating mechanisms between the two species. However, viable adults of the hybrids F1 and F2 were produced from both parental F. hepatica and F. gigantica. The hybrids inherited phenotypic characteristics such as ratio of body length and width and infectivity to rats from parental Fasciola hepatica and F. gigantica. These findings suggest that reproductive isolation is incomplete between Fasciola hepatica and F. gigantica. Adults of the hybrids F1 and F2 were completely different in mode of reproduction from aspermic Fasciola forms that occur in Asia and seem to be offspring originated from hybridization between F. hepatica and F. gigantica and to reproduce parthenogenetically.

RESUMEN

INTRODUCTION: Infections of enterobacteria producing extended-spectrum -lactamases place a heavy burden on health systems. Little is known in osteoarticular infections, so this work studied the prevalence of these infections in a third-level hospital. MATERIAL AND METHODS: Prevalence study in patients of a Traumatology Service during 2016, with infection criteria provided by the CDC in Atlanta, Georgia. The VITEK® 2 AST-N272 (bioMérieux) system was used for bacterial identification at the species level and for antimicrobial susceptibility tests. RESULTS: 7.85% (n = 86) were reported with osteoarticular infections; 22.09% (n = 19) were by enterobacteria BLEEs. An average of 77.1 days of hospitalization (SD 37.7) (46-200 days); isolation of the microorganism occurred 15 days after entry. Sixteen (84.2%) patients had osteomyelitis, three (15.8%) had a prosthetic knee or hip infection. The average number of treatment days was 60 days (21-129 days). Eighteen patients (94.7%) were discharged with resolution of their infectious picture; one patient died with infection over aggregated pneumonia due to carbapenem-resistant K. pneumoniae. DISCUSSION: The prevalence of osteoarticular infections by enterobacteria BLEEs could not be accurately calculated, but we consider it to be within what is expected, infection control measures require higher standards and there is a lack of development programs to use antimicrobials rationally to control the emergence of these pathologies.


INTRODUCCIÓN: Las infecciones por enterobacterias productoras de -lactamasas de espectro extendido (BLEEs) ocasionan una gran carga a los sistemas de salud. Poco se conoce de las infecciones osteoarticulares, por lo que este trabajo estudió la prevalencia de estas infecciones en un hospital de tercer nivel. MATERIAL Y MÉTODOS: Estudio de prevalencia en pacientes de un servicio de traumatología durante 2016, con criterios de infección proporcionados por el CDC de Atlanta, Georgia. Se utilizó el sistema VITEK® 2 AST-N272 (bioMérieux) para la identificación bacteriana a nivel de especie y para las pruebas de susceptibilidad antimicrobiana. RESULTADOS: Se reportaron 7.85% (n = 86) con infecciones osteoarticulares; 22.09% (n = 19) fueron por enterobacterias BLEEs. Con un promedio de 77.1 días de hospitalización (DE 37.7) (46-200 días); el aislamiento del microorganismo se produjo 15 días posteriores al ingreso; 16 (84.2%) pacientes presentaron osteomielitis, tres (15.8%) tuvieron infección protésica de rodilla o cadera. El promedio de días de tratamiento fue de 60 días (21-129 días); 18 pacientes (94.7%) fueron dados de alta con resolución de su cuadro infeccioso; un paciente falleció con infección sobreagregada por neumonía debida a K. pneumoniae resistente a carbapenémicos. DISCUSIÓN: La prevalencia de infecciones osteoarticulares por enterobacterias BLEEs no se pudo calcular con precisión, pero consideramos que se encuentra dentro de lo esperado, las medidas de control de infecciones requieren tener estándares más elevados y falta desarrollar programas de uso racional de antimicrobianos para controlar la aparición de estas patologías.

RESUMEN

Serum biomarkers associated with Fasciola hepatica infection of Corriedale sheep were analysed during the first 12 weeks of infection using surface-enhanced laser desorption ionisation time of flight mass spectrometry (SELDI-TOF MS). In the discovery phase of analysis, pooled sera collected at week 0 and at each week p.i. to week 12 were fractionated by anion-exchange chromatography and the protein mass fingerprints obtained in individual fractions were in the M/z range 1.5-150 kDa. A total of 2302 protein clusters (peaks) were identified that varied between time-points following infection with peaks increasing or decreasing in intensity, or showing transient variation in intensity, during the 12 weeks of parasite challenge. In the validation phase, candidate biomarkers in sera of individual sheep at weeks 3 and 9 p.i. were analysed, identifying 100 protein peaks, many of which are small peptides <10 kDa in size: 54% of these peaks were up-regulated in intensity at week 3 or 9 p.i. Twenty-six biomarkers were chosen for further study, ranging in size from 1832 to 89,823 Da: six biomarkers were up-regulated at weeks 3 and 9 p.i., 16 biomarkers were up-regulated only at week 9 p.i. and four biomarkers were down-regulated at week 9 p.i. Two biomarkers up-regulated at week 9 were identified as transferrin (77.2 kDa) and Apolipoprotein A-IV (44.3 kDa), respectively. The results show that the interaction between the host and F. hepatica is complex, with changes in biomarker patterns beginning within 3 weeks of infection and either persisting to weeks 9-12 or showing transient changes during infection. Identification of biomarkers expressed during ovine fasciolosis may provide insights into mechanisms of pathogenesis and immunity to Fasciola and may assist in the rational development and delivery of vaccines.

RESUMEN

This study aimed to identify internal and external workload demands in professional referees, and to analyse the influence of the situational variables Game Period and Game Action. Three professional referees of the highest category were monitored during a national elite game. WIMU PRO™ inertial devices were used for workload monitoring via microtechnology, ultra-wide band and heart rate (HR) telemetry. The referees worked at around 82%HRMAX and spent 75% of the time at walking-jogging speed (0-12km/h). Game Action influenced the external workload (total distance and per intensities, impacts, player load, maximum and mean speed) while Game Period influenced the internal load (HRMEAN, HRMAX, %HRMAX and per intensities). Workload quantification in competition and the evaluation of the effect of situational variables are essential for setting up performance profiles and designing individual programmes that improve the training of basketball referees.

RESUMEN

Luego del inicio de las campañas de vacunación masiva contra la infección por COVID-19, se han publicado una serie de reportes que muestran la posible asociación entre la vacuna y alteraciones de la función tiroidea. Desde entonces, múltiples teorías han intentado explicar este hallazgo, en su mayoría de índole autoinmune. Dentro de estas destaca el síndrome autoinmune-autoinflamatorio secundario a adyuvantes (ASIA), que podría generar desórdenes tiroideos de novo o exacerbar los ya existentes. Presentamos dos casos de enfermedad de Graves Basedow posterior al uso de Coronavac. Ambas pacientes presentaron características similares a las descritas en la literatura y cumplen con los criterios de ASIA. No obstante, los beneficios de las vacunas superan los posibles riesgos asociados.


After the beginning of COVID-19 vaccination campaigns, a number of reports have shown the potential association between vaccines and thyroid disfunction. Since then several theories have tried to explain this finding, mostly autoinmmune. One of them is the autoimmune/inflammatory syndrome induced by adjuvants, that could trigger or exacerbate thyroid disease. We present two cases of Graves' disease post Coronavac vaccination. Both pacients share similar features than cases published previously and meet criteria for ASIA syndrome. Nevertheless, the benefts of vaccination largely outweigh any adverse events associated.

RESUMEN

The purpose of the present study was to analyze the chronotropic and cardiac autonomic response of a motorcyclist during the 7th race week of the FIM-CEV Repsol Moto2 European Championship through heart rate (HRAVG) and sympathetic-parasympathetic ratio (RS-Ps). The effect and relationships of sessions, laps and track segments were analyzed by MANOVA test with Bonferroni post-hoc and Pearson’s r. A low effect of the segments in RS-Ps (p<.01; wp2=0.03), and high effect of the sessions (p<.01; wp2=0.72), laps (p<.01; wp2=0.95) and the interaction between sessions and laps (p<.01; wp2=0.62) in HRAVG were found. Also, a tendency of increasing HRAVG was found with sessions (r=.315; p<0.01) and laps (r=.280; p<0.01). No significant correlations were found with RS-Ps. While HRAVG can be used as a fatigue index during motorcycling competition, RS-Ps indicates the significant rider’s stress at specific segments of the track, being important both variables for improving the riders’ performance.

El objetivo del presente estudio fue analizar la respuesta cronotrópica y cardiaca autónoma de un piloto de motociclismo durante la 7a prueba del Campeonato de Europa FIM-CEV Repsol Moto2 mediante frecuencia cardíacamedia (FCMEDIA) y ratio simpático-parasimpático (RS-Ps). El efecto y relaciones de las sesiones, vueltas y segmentos del circuito fue analizado mediante MANOVA conpost-hoc Bonferroni y r de Pearson. Se encontró bajo efecto de los segmentos enRS-Ps (p<.01; ωp2=0.03), y alto efecto de sesiones (p<.01; ωp2=0.72), vueltas (p<.01; ωp2=0.95) e interacción sesiones-vueltas (p<.01; ωp2=0.62) en FCMEDIA. Además, se hallo una tendencia de incremento de FCMEDIA respecto a sesiones (r=.315; p<.01) y vueltas (r=.280; p<.01). No se encontraron correlaciones significativas con RS-Ps. La FCMEDIA puede utilizarse como un indicador de fatiga durante la competición, mientras que el RS-Ps indicaría el estrés significativo del piloto en segmentos específicos del circuito, siendo ambas variables importantes para mejorar el rendimiento del piloto.

RESUMEN

PURPOSE: To analyse any delays in breast cancer diagnosis and surgical treatment, influence of clinical and biological factors and influence of delays on survival. METHODS/PATIENTS: A descriptive, observational, and retrospective study was conducted between 2006 and 2016 on stages I-III breast cancer patients. This is a retrospective review of health records to collect data on delays, patients' clinical data, biological features of the tumour and information on treatment. Mortality data from the National Death Index. RESULTS: In 493 evaluable patients, the median of days from the first symptom to mammography, biopsy, and surgery was 41, 57, and 92, respectively. The median of days from screening mammography to biopsy and surgery was 10 and 51, respectively. From biopsy to surgery, the median was 34 days in every case. Over the last 5 years, an increase in biopsy-surgery delay has been observed (p = 0.0001). Tumour stages I and II vs. stage III (RR 1.74. 95% CI 1.08-2.80, p = 0.027), diagnosis in screening (RR 0.66. 95% CI 0.45-0.96, p = 0.030), and use of magnetic resonance imaging (RR 2.08. 95 CI 1.21-3.56, p = 0.008) condition a greater biopsy-surgery delay. No influence of delays on survival has been identified. CONCLUSIONS: Delays in diagnosis and surgery in the case of women diagnosed on the basis of symptoms may be improved. There is a temporary tendency to a greater delay in surgery. Some clinical and biological factors must be taken into account to optimise delays. Survival results are not adversely affected by delays.

RESUMEN

BACKGROUND: In maternal PKU, protein substitute (PS) is provided by phenylalanine (PHE)-free l-amino acids (AA), but glycomacropeptide-based protein substitute (GMP) is an alternative consideration. OBJECTIVE: To describe the first Portuguese Maternal Phenylketonuria (MPKU) partially managed with GMP. CASE REPORT: A 31 year old MPKU female with classical PKU (mutations P281L/P281L), diagnosed by newborn screening, had a lifelong history of poor metabolic control. She has a history of partial bicornuate uterus and had a previous miscarriage in the first trimester. Pre-conception, her median blood PHE was 462 µmol/L but throughout pregnancy the median reduced to 258 µmol/L. GMP provided 30 g/day protein equivalent (46 mg/day PHE). Total protein equivalent from PS increased from 58 to 86 g/day during pregnancy but AA provided all additional protein equivalent intake. Both GMP and AA were well tolerated with no morning sickness. Normal morphologic evaluation and adequate fetal growth with cephalic biometry near the 5th percentile was determined. The infant was born at 39.3 weeks: weight 2570 g (3rd percentile), length 47.5 cm (10th percentile) and head circumference (HC) of 31.5 cm (1st percentile). In the neonatal period, the infant had craniofacial dimorphism with metopic suture prominence. Father also had bitemporal narrowing. By 12 months of age, the infant's weight (15th percentile), length (50th percentile) and HC (10th-50th percentile) were normal although bitemporal narrowing persisted. CONCLUSIONS: This is the first case reporting the use of GMP in MPKU. Its PHE content did not adversely affect metabolic control although it only provided part of the PS intake. Some intrauterine development delay occurred in the last trimester, although we consider that this is unlikely to be associated with MPKU syndrome or the use of GMP. More published data is essential to examine the impact of using GMP in MPKU on morning sickness severity and aversion, maternal weight gain, blood amino acid concentrations and variability of blood PHE concentrations.

RESUMEN

Este estudio pretende: i) describir las exigencias tácticas objetivas (área ocupada por el equipo, AOE) y subjetivas (percepción subjetiva del espacio ocupado, PSEO), ii) identificar la variabilidad inter-sujeto y explorar la relación entre AOE y PSEO, y iii) comparar las exigencias entre defensa y ataque durante la realización de juegos reducidos. Doce jugadores semiprofesionales de fútbol fueron monitoreados mediante dispositivos inerciales WIMU PRO®. Los resultados indican un AOE (ataque=257.6±60.6; defensa=120.3±37.8 m2) y PSEO (ataque=3.5±0.7; defensa=2.7±0.6 a.u.). Se encontraron diferencias entre fase de ataque y defensa en ambas variables (p>0.001; AOE, d=2.72; PSEO, d=1.23) y una alta relación entre ambos indicadores (r=0.92). En conclusión, las variables AEO y PSEO discriminaron el efecto de la fase de juego y el día de entrenamiento. Son necesarias futuras investigaciones con un mayor tamaño muestral para confirmar la validez de la PSEO. (AU)


This study aims to: i) describe the objective tactical demands (surface area occupied by team, AOE) and subjective (spatial perception of occupied area, PSEO), ii) identify the inter-subjects variability and the relationship between AOE and PSEO iii) to compare the demands between offensive and defensive phases during small-sided games. Twelve semi-professional football players were tracked using WIMU PRO®. The results indicated an AOE (attack=257.6±60.6; defense=120.3±37.8 m2) and PSEO (attack=3.5±0.7; 2.7±0.6 a.u.). Differences were found between attack and defense phase in both variables (p>0.001; AOE, d=2.72; PSEO, d=1.23) and high relationship between both indicators (r=0.92). In conclusion, the variables AEO and PSEO discriminated the effect of the game phase and the training day. Future research with a larger sample size is necessary to confirm the validity of the PSEO.
