Implementation of a major trauma team. Analysis of activation and care times in patients admitted to the ICU.

OBJECTIVE: To analyze the factors associated with the activation of the severe trauma care team (STAT) in patients admitted to the ICU, to measure its impact on care times, and to analyze the groups of patients according to activation and level of anatomical involvement. DESIGN: Prospective cohort study of severe trauma admitted to the ICU. From June 2017 to May 2019. Risk factors for the activation of the STAT analysed with logistic regression and CART type classification tree. SETTING: Second level hospital ICU. PATIENTS: Patients admitted consecutively. INTERVENTIONS: No. MAIN VARIABLES OF INTEREST: STAT activation. Demographic variables. Injury severity (ISS), intentionality, mechanism, assistance times, evolutionary complications, and mortality. RESULTS: A total of 188 patients were admitted (46.8% of STAT activation), median age of 52 (37-64) years (activated 47 (27-62) vs not activated 55 (42-67) P = 0.023), males 84.0%. No difference in mortality according to activation. The logistic model finds as factors: care (16.6 (2.1-13.2)) and prehospital intubation (4.2 (1.8-9.8)) and severe lower extremity injury (4.4 (1.6-12.3)). Accidental fall (0.2 (0.1-0.6)) makes activation less likely. The CART model selects the type of trauma mechanism and can separate high and low energy trauma. CONCLUSIONS: Factors associated with STAT activation were prehospital care, requiring prior intubation, high-energy mechanisms, and severe lower extremity injuries. Shorter care times if activated without influencing mortality. We must improve activation in older patients with low-energy trauma and without prehospital care.

[Incidence of alarm criteria and attitude towards patients with headache attended in emergency departments]. / Incidencia de criterios de alarma y actitud frente a los pacientes con cefalea atendidos en urgencias.

INTRODUCTION: Alarm criteria make it possible to identify persons who visit emergency services because of severe secondary headaches. AIMS: To determine the socio-demographic characteristics of the patients who visit emergency departments due to headache, the incidence of alarm criteria, treatment and the diagnosis after one year's follow-up. PATIENTS AND METHODS: We conducted a retrospective observational cross-sectional study of the persons attended in the emergency department of the Arnau de Vilanova Hospital between June 2014 and May 2015 due to headache. RESULTS: A total of 303 persons were identified, of whom 165 were finally included in the study. There was a predominance of women (66.7%). The mean age was 41.2 ± 15.9 years. Only 16.4% were referred from primary care and 52 (31.5%) presented alarm criteria. A computerised tomography head scan was performed in half of these cases, and lumbar puncture was carried out in four of them (7.7%). A serious cause of headache was found in four cases (2.4%). After one year of follow-up, three patients who did not initially visit because of alarm criteria were diagnosed with severe diseases of the central nervous system, and 23 (13.9%) returned to the emergency department for the same reason. CONCLUSIONS: Only one out of every two patients meets the alarm criteria. The proportion of severe secondary headache is really low. The multidisciplinary management of headache needs to be improved in our setting to prevent people visiting the emergency department due to primary headaches without any alarm criteria.

TITLE: Incidencia de criterios de alarma y actitud frente a los pacientes con cefalea atendidos en urgencias.Introduccion. Los criterios de alarma permiten identificar a las personas que consultan por cefaleas secundarias graves en los servicios de urgencias. Objetivo. Determinar las caracteristicas sociodemograficas de los pacientes que acuden a urgencias por cefalea, la incidencia de criterios de alarma, el tratamiento y el diagnostico tras un año de seguimiento. Pacientes y metodos. Estudio transversal retrospectivo y observacional de personas atendidas en el servicio de urgencias del Hospital Arnau de Vilanova entre junio de 2014 y mayo de 2015 por cefalea. Resultados. Se identifico a un total de 303 personas, de las cuales 165 se incluyeron finalmente en el estudio. Hubo un predomino de mujeres (66,7%). La edad media fue de 41,2 ± 15,9 años. Solo un 16,4% fue derivado desde atencion primaria y 52 (31,5%) presentaban criterios de alarma. En la mitad de estos casos se realizo una tomografia computarizada craneal, y en 4 (7,7%), una puncion lumbar. Se identifico una causa grave de la cefalea en 4 casos (2,4%). Tras un año de seguimiento, tres pacientes que inicialmente no consultaron por criterios de alarma fueron diagnosticados de enfermedades graves del sistema nervioso central, y 23 (13,9%) volvieron a urgencias por el mismo motivo. Conclusiones. Solo uno de cada dos pacientes cumple criterios de alarma. La proporcion de cefalea secundaria grave es realmente baja. Es necesario mejorar el abordaje multidisciplinar de la cefalea en nuestro ambito para evitar la consulta a urgencias por cefaleas primarias sin criterios de alarma.

Influence of drying process and particle size of persimmon fibre on its physicochemical, antioxidant, hydration and emulsifying properties.

Persimmon, given its current surplus production, could be an alternative source for the extraction of certain interesting ingredients for the food industry and human health, such as fibre. Thus, the aim of this study was to analyse the influence of hot air and freeze-drying, as well as the particle size of fibre extracted from persimmon peels or pulp on their physicochemical, antioxidant, hydration and emulsifying properties, compared to commercial fibres (from peach, lemon, orange and apple). The results showed that both freeze-dried persimmon pulp and freeze-dried peel had better hydration properties and oil holding capacity than other fibres analysed, although the swelling capacity was higher for lemon fibre. Freeze-dried persimmon peel fibre showed higher values of emulsion stability than commercial fibres. Finally, the antioxidant activity of the smallest sized persimmon peel fibre obtained by freeze-drying was higher than that for lemon, orange and peach fibre.

Removal of anti-Stokes emission background in STED microscopy by FPGA-based synchronous detection.

In stimulated emission depletion (STED) microscopy, the role of the STED beam is to de-excite, via stimulated emission, the fluorophores that have been previously excited by the excitation beam. This condition, together with specific beam intensity distributions, allows obtaining true sub-diffraction spatial resolution images. However, if the STED beam has a non-negligible probability to excite the fluorophores, a strong fluorescent background signal (anti-Stokes emission) reduces the effective resolution. For STED scanning microscopy, different synchronous detection methods have been proposed to remove this anti-Stokes emission background and recover the resolution. However, every method works only for a specific STED microscopy implementation. Here we present a user-friendly synchronous detection method compatible with any STED scanning microscope. It exploits a data acquisition (DAQ) card based on a field-programmable gate array (FPGA), which is progressively used in STED microscopy. In essence, the FPGA-based DAQ card synchronizes the fluorescent signal registration, the beam deflection, and the excitation beam interruption, providing a fully automatic pixel-by-pixel synchronous detection method. We validate the proposed method in both continuous wave and pulsed STED microscope systems.

Sleep-related disorders in Latin-American children with atopic dermatitis: a case control study

BACKGROUND: Atopic dermatitis (AD) has been associated with impairment of sleep. The aim of this study was to evaluate sleep disorders in AD Latin-American children (4-10 years) from nine countries, and in normal controls (C). METHODS: Parents from 454 C and 340 AD children from referral clinics answered the Children Sleep Habits Questionnaire (CSHQ), a one-week retrospective 33 questions survey under seven items (bedtime resistance, sleep duration, sleep anxiety, night awakening, parasomnias, sleep-disordered breathing and daytime sleepiness). Total CSHQ score and items were analysed in both C and AD groups. Spearman's correlation coefficient between SCORAD (Scoring atopic dermatitis), all subscales and total CSHQ were also obtained. RESULTS: C and AD groups were similar regarding age, however, significantly higher values for total CSHQ (62.2±16.1 vs 53.3±12.7, respectively) and items were observed among AD children in comparison to C, and they were higher among those with moderate (54.8%) or severe (4.3%) AD. Except for sleep duration (r=−0.02, p = 0.698), there was a significant Spearman's correlation index for bedtime resistance (0.24, p < 0.0001), sleep anxiety (0.29, p < 0.0001), night awakening (0.36, p < 0.0001), parasomnias (0.54, p < 0.0001), sleep-disordered breathing (0.42, p < 0.0001), daytime sleepiness (0.26, p < 0.0001) and total CSHQ (0.46, p < 0.0001). AD patients had significantly higher elevated body mass index. CONCLUSION: Latin-American children with AD have sleep disorders despite treatment, and those with moderate to severe forms had marked changes in CSHQ

Sleep disorders in Latin-American children with asthma and/or allergic rhinitis and normal controls

BACKGROUND: Asthma and/or allergic rhinitis have been associated with sleep disorders. The aim of this study was to evaluate sleep disorders in Latin-American children (4-10 years) from nine countries, with persistent asthma (A) and/or allergic rhinitis (AR) and in normal controls (C). METHODS: Parents from 454 C children and 700 A and/or AR children followed up in allergy reference clinics completed the Children's Sleep Habits Questionnaire (CSHQ) which is a retrospective one-week questionnaire composed of 33 questions composed of seven subscales (bedtime resistance, sleep duration, sleep anxiety, night wakings, parasomnias, sleep-disordered breathing and daytime sleepiness). The total scale of CSHQ and the subscales were compared between groups C and A+AR, A (n=285) vs. AR (n=390), and between controlled A (CA, n=103) vs. partially controlled/uncontrolled A (UA, n=182). RESULTS: The comparison between C and A+AR showed no significant differences in age (6.7 years vs. 7.0 years, respectively), mean Body Mass Index and total scale of CSHQ (53.3 vs. 63.2, respectively) and the subscales were significantly higher in the A+AR group. Comparison between groups A and AR, except for sleep anxiety, showed significantly higher values for CSHQ total scale (66.9 vs. 61.0, respectively) and subscales for group A. The UA group showed significantly higher values for total CSHQ scale and subscales in comparison to CA (71.1 vs. 59.4, respectively). CONCLUSIONS: Latin-American children with asthma and/or allergic rhinitis showed sleep disorders identified by the CSHQ when compared to normal controls. Despite being treated, asthma causes sleep impairment, especially when uncontrolled

Foot deformities in Renaissance paintings. A mystery of symbolism, artistic licence, illusion and true representation in five renowned Renaissance painters.

Although Renaissance artists were skilled in representing normal anatomy, a close look at some paintings reveals anatomical variations in the depiction of the feet of human figures. A systematic review has identified 25 paintings by five artists in which the presumptive medico-artistic diagnosis of congenital or acquired foot deformity seems to be varyingly present. The connection between these five painters and what factors have influenced artists' style in the depiction of such deformities is discussed. The possible iconography and medical-historical meaning of such variations, as well as the possibility of artistic licence and real representation that drove the painters to depict these deformities, is explored and debated.

Assessment of the reproducibility of oligoclonal IgM band detection for its application in daily clinical practice.

BACKGROUND: The presence of oligoclonal IgM bands (OCMB) in cerebrospinal fluid (CSF) is an unfavourable prognostic marker in multiple sclerosis. There is no commercial test to investigate OCMB status. However, a sensitive and specific isoelectrofocusing (IEF) and western blot method was described. We aimed to study the inter-centre reproducibility of this technique, a necessary condition for a reliable test to be incorporated into clinical practice. METHODS: The presence of OCMB was analysed by IEF and western blot with prior reduction of pentameric IgM. We assayed the reproducibility of this test in a blinded multicentre study performed in 13 university hospitals. Paired-CSF and serum samples from 52 neurological patients were assayed at every centre. RESULTS: Global analysis rendered a concordance of 89.8% with a kappa value of 0.71. CONCLUSION: These data indicate that OCMB detection by means of IEF and western blot with IgM reduction shows a good interlaboratory reproducibility and thus can be used in daily clinical setting.

Influence of calcium lactate and modified atmosphere on respiration rate, optical and mechanical properties of sliced persimmon.

The aim of this study was to evaluate the effect of a modified atmosphere (5% and 10% of CO2) and calcium lactate treatment on the respiratory metabolism of minimally processed persimmon. A static system to measure changes in the composition of the headspace was used. Composition, texture and colour were also analysed. Persimmon slices were evaluated immediately after the washing treatment and after the O2 composition had decreased to 17% to avoid changes in the metabolic pathway. All samples were stored at 4 ℃. The results showed that modified atmosphere did not affect compositional properties, although there was a slight increase in pH values at the end of each treatment. Calcium lactate treatment reduced the respiration rate, in terms of O2, in samples kept in air. Additionally, a calcium lactate effect was immediately observed on mechanical properties after the washing stage. On the other hand, luminosity and b* coordinate decreased in unwashed and calcium lactate samples kept in 5% CO2.
