RESUMEN

Before the colonial period, California harboured more language variation than all of Europe, and linguistic and archaeological analyses have led to many hypotheses to explain this diversity1. We report genome-wide data from 79 ancient individuals from California and 40 ancient individuals from Northern Mexico dating to 7,400-200 years before present (BP). Our analyses document long-term genetic continuity between people living on the Northern Channel Islands of California and the adjacent Santa Barbara mainland coast from 7,400 years BP to modern Chumash groups represented by individuals who lived around 200 years BP. The distinctive genetic lineages that characterize present-day and ancient people from Northwest Mexico increased in frequency in Southern and Central California by 5,200 years BP, providing evidence for northward migrations that are candidates for spreading Uto-Aztecan languages before the dispersal of maize agriculture from Mexico2-4. Individuals from Baja California share more alleles with the earliest individual from Central California in the dataset than with later individuals from Central California, potentially reflecting an earlier linguistic substrate, whose impact on local ancestry was diluted by later migrations from inland regions1,5. After 1,600 years BP, ancient individuals from the Channel Islands lived in communities with effective sizes similar to those in pre-agricultural Caribbean and Patagonia, and smaller than those on the California mainland and in sampled regions of Mexico.

RESUMEN

Aiming to improve the quality of cocoa, preconditioning of cocoa after harvesting and before fermentation has become an on-farm processing step of great interest in recent times. The present work aimed to evaluate the influence of a pre-drying process on the volatile composition of Ecuadorian bulk (Forastero and CCN-51) and fine-flavour (ETT103 and LR14) cocoa at the end of primary processing. A total of 63 volatile compounds including aldehydes, alcohols, acids, ketones, esters, terpenes, lactones and other miscellaneous compounds were identified in cocoa samples by HS-SPME-GC-MS. The use of a pre-drying step revealed a varietal homogenization and a reduction in the fermentation time, making this preconditioning step an inexpensive and attractive option for farmers. Moreover, different varietal behaviour was observed after pre-drying, the fine-flavour varieties obtaining a clear improvement in aromatic quality with higher levels of compounds imparting positive notes.

RESUMEN

Introducción: Los diabéticos muestran una disminuida función del sistema inmune. Su complicación más temida es la aparición de las úlceras del pie. El Heberprot-P® tiene efectos beneficiosos en la curación de estas úlceras. Objetivo: Evaluar el efecto de la inmunidad celular en el tratamiento de las úlceras del pie diabético con Heberprot-P®. Métodos: Se realizó un estudio observacional, prospectivo, de serie de casos, en 30 pacientes con úlcera de pie diabético, ingresados en el Instituto Nacional de Angiología y Cirugía Vascular. Se administraron 75 µg de Heberprot-P®, tres veces por semana, a través de vías peri- e intralesional, durante ocho semanas. Se evaluaron las variables edad, sexo, glucemia en ayunas, creatinina, urea, ácido úrico, prueba de hipersensibilidad retardada, porcentaje de granulación, tiempo de cierre de la lesión y localización de la úlcera, antes de comenzar el tratamiento, a las 4 y 8 semanas. Resultados: Se precisó un predominio del 60 por ciento en el sexo femenino y del color de piel blanca. Los niveles de glucemia y creatinina se comportaron más elevados en los anérgicos; la urea fue similar tanto en anérgicos como en reactivos; y el ácido úrico resultó mayor en hombres reactivos y en mujeres anérgicas. Hubo mayor proporción de reactivos (63,6 por ciento), que en la cuarta semana presentaron un tejido de granulación igual o mayor al 50 por ciento; y a la octava, igual o mayor al 70 por ciento. Conclusiones: La condición en los pacientes diabéticos de ser reactivo a las pruebas de hipersensibilidad retardada con úlcera de pie diabético de tipo neuropática, tratados con Heberprot-P®, está asociada directamente con una mejor respuesta en la cicatrización de sus lesiones, mediante la formación del tejido de granulación, que favorece el cierre total o parcial de la lesión. Esto no ocurrió con los pacientes anérgicos a dicha prueba(AU)


Introduction: Diabetics show decreased immune system function. Its most feared complication is the appearance of foot ulcers. Heberprot-P® has beneficial effects in healing these ulcers. Objective: To assess the effect of cellular immunity in the treatment of diabetic foot ulcers with Heberprot-P®. Methods: An observational, prospective, case series study was conducted in 30 patients with diabetic foot ulcer admitted to the National Institute of Angiology and Vascular Surgery. 75 µg of Heberprot-P®, three times a week, were administered through peri- and intralesional routes, during eight weeks. The variables age, sex, fasting blood glucose, creatinine, urea, uric acid, delayed hypersensitivity test, percentage of granulation, time of closure of the lesion and location of the ulcer, before starting treatment, at 4 and 8 weeks were evaluated. Results: A predominance of 60 % in females and white skin color were specified. Blood glucose and creatinine levels behaved higher in the anergics; urea was similar in both anergics and reagents; and uric acid was higher in reactive men and anergic women. There was a higher proportion of reagents (63.6 por ciento), which in the fourth week presented a granulation tissue equal to or greater than 50 por ciento; and at the eighth week, it was equal to or greater than 70 por ciento. Conclusions: The condition of being reactive to delayed hypersensitivity tests in diabetic patients with diabetic foot ulcer of neuropathic type, treated with Heberprot-P® is directly associated with a better response in the healing of their lesions, through the formation of granulation tissue, which favors the total or partial closure of the lesion. This did not occur with patients who were anergic to this test(AU)

RESUMEN

PURPOSE OF REVIEW: Familial hypercholesterolemia is a high cardiovascular risk disorder. We will review the role of lipoprotein(a) in cardiovascular risk and in aortic valve stenosis in familial hypercholesterolemia, as well as its association with their phenotype, and strategies to identify this high-risk population. RECENT FINDINGS: Patients with familial hypercholesterolemia have higher lipoprotein(a) levels mainly due to an increased frequency of LPA variants, and the cardiovascular risk is increased twofolds when both conditions coexist. Also, an increased risk for aortic valve stenosis and valve replacement has been observed with high lipoprotein(a) levels. Assessment of lipoprotein(a) during the cascade screening for familial hypercholesterolemia is a good opportunity to identify this high-risk population. High cardiovascular risk in familial hypercholesterolemia is increased even more when lipoprotein(a) is also elevated. Measurement of lipoprotein(a) in these patients is crucial to identify those subjects who need to intensify LDL-cholesterol reduction pending availability of lipoprotein(a)-specific treatments.

RESUMEN

Background: Quality of attention is assessed through patient´s satisfaction about attention received. A validated fast scale to asses it in emergency medical services is necessary. Objective: To design and validate the Patient Satisfaction at Emergency Services Scale (ERSAPUR). Material and methods: Longitudinal, process study to assess the new satisfaction scale at Emergency room in a second level attention unit. PHASE I: ERSAPUR was designed by 10 quality and emergencies attention experts; redaction was approved by 20 patients consecutively. PHASE II: After written consent, ERSAPUR and Encuesta de Satisfacción del Servicio de Urgencias del Hospital Universitari de Bellvitge de Barcelona scales were applied to patients attended at emergency room, more than18 years-old. Those patients with psychiatric disease, mental handicap or non-spanish parlor were excluded. ERSAPUR was reapplied by phone 7-10 days later. Cronbach´s alfa was used for internal fiability, Spearman´s rho for convergent validity, and Intraclass correlational coefficient (CCI) for test-retest; p ≤ 0.05 was considered significant. Results: 260 patients answered both scales. Medical and nurses cares produced the highest satisfaction. Clean and waiting time produced the highest dissatisfaction. Cronbach´s Alpha = 0.873, Spearman´s rho = 0.654, CCI = 0.75 (p ≤ 0.01). Conclusions: ERSAPUR is a valid and fiable scale, and it´s a useful instrument to assess the quality of attention in Emergency room services.


Introducción: la calidad de la atención puede medirse por la satisfacción del paciente por la atención recibida, por lo que es necesaria una escala rápida validada que la evalúe en los servicios de urgencias. Objetivo: crear y validar la Escala Rápida de Satisfacción del Paciente de Urgencias (ERSAPUR). Material y métodos: estudio de proceso, longitudinal, para evaluar la nueva escala de satisfacción en urgencias, en una unidad de segundo nivel de atención. Fase I: 10 expertos en calidad de atención y en urgencias elaboraron la ERSAPUR, que obtuvo acuerdo en redacción por 20 usuarios consecutivos. Fase II: con consentimiento informado, se aplicaron la ERSAPUR y la Encuesta de Satisfacción del Servicio de Urgencias del Hospital Universitari de Bellvitge de Barcelona en pacientes atendidos en urgencias, mayores de 18 años; se excluyeron los pacientes con enfermedad psiquiátrica, retraso mental, encefalopatía y no hispanohablantes. Se reaplicó la ERSAPUR telefónicamente 7 a 10 días después. Se utilizó para consistencia interna, alfa de Cronbach; para validez concurrente, rho de Spearman, y para prueba-reprueba el coeficiente de correlación intraclase (CCI), la p ≤ 0.05 se consideró significativa. Resultados: se encuestó a un total de 260 pacientes. La satisfacción mayor fue por la atención de médicos y enfermería, y la mayor insatisfacción por limpieza y tiempo de espera, alfa de Cronbach = 0.873, Spearman = 0.654, CCI = 0.75(p ≤ 0.01). Conclusiones: la ERSAPUR es válida, consistente y útil para evaluar rápidamente la calidad de la atención en Urgencias.

RESUMEN

RESUMEN Introducción: Las espondiloartritis son un grupo de enfermedades inflamatorias crónicas con afectación principalmente del esqueleto axial y también de articulaciones periféricas. En cuanto al metabolismo óseo de estos pacientes, se ha observado en algunos estudios que existen niveles más bajos de vitamina D en pacientes con espondiloartritis. Objetivo: Estimar la prevalencia de déficit/insuficiencia de vitamina D, el metabolismo fosfocálcico y sus implicaciones en una cohorte de pacientes con espondiloartritis. Metodología: Estudio observacional, descriptivo y transversal. Se llevó a cabo una revisión retrospectiva de la base de datos de pacientes con espondiloartritis que fueron atendidos en las consultas externas del Servicio de Reumatología del Hospital General Universitario de Ciudad Real entre junio del 2018 y junio del 2019. Las variables se describieron usando medidas de frecuencia o medidas de tendencia central/dispersión según correspondiera. Resultados: Se analizaron 115 pacientes, de los cuales 64 fueron hombres y 51 mujeres, con una edad media de 45,97 años (± 13,41 DE). Del total de los pacientes, 59 presentaron espon dilitis anquilosante, 24 artropatía psoriásica, 9 artritis asociada a enfermedad inflamatoria intestinal, 12 espondiloartritis axial no radiográfica y 11 artritis reactiva. Los niveles de vitamina D fueron de 23,81 ng/ml (±10,5 DE), con un 77,4% de los pacientes con cifras de déficit/insuficiencia de vitamina D. Agrupados por el subtipo de espondiloartritis y según las cifras de déficit/insuficiencia de vitamina D, 45 pacientes tenían espondilitis anquilo sante, 19 artropatía psoriásica, 9 artritis asociada a enfermedad inflamatoria intestinal, 7 espondiloartritis axiales no radiográficas y 9 artritis reactivas. Además, el déficit de vita mina D (< 20 ng/ml) se presentaba la mayoría de las veces en las estaciones de primavera e invierno, con 31 y 26 pacientes respectivamente. Conclusiones: Una optimización de los niveles de vitamina D puede implicar una mejoría en la situación clínica del paciente, medida tanto por BASDAI y DAPSA como por PCR y VSG. En consecuencia, se recomienda la monitorización y suplementación de vitamina D en pacientes con hipovitaminosis D.


ABSTRACT Introduction: Spondyloarthritis is a group of chronic inflammatory diseases that mainly affect the axial skeleton, and also the peripheral joints. In bone metabolism studies on these patients, it has been observed that there are lower levels of vitamin D in patients with spondyloarthritis. Objective: To estimate the prevalence of vitamin D deficiency / insufficiency, as well as calcium/ phosphate metabolism and their implications in a cohort of patients with spondyloarthritis. Methodology: Observational, descriptive, and cross-sectional study. A retrospective review of the databases was carried out on patients with spondyloarthritis who were treated in the outpatient clinics of the Rheumatology Department of the General University Hospital of Ciudad Real between June 2018 and June 2019. Variables are described using frequency and central tendency / dispersion measurements as appropriate. Results: The study included 115 patients, of whom 64 were men and 51 women, with a mean age of 45.97 years (± 13.41 SD). They included 59 patients with ankylosing spondylitis, 24 with psoriatic arthropathy, 9 arthritis associated with inflammatory bowel disease, 12 non-radiographic axial spondylarthritis, and 11 reactive arthritis. Vitamin D levels were 23.81 ng/ml (± 10.5 SD), with 77.4% of patients with vitamin D deficiency / insufficiency levels. Grouped by the spondylarthritis subtype, and according to vitamin D deficiency / insufficiency, 45 patients had ankylosing spondylitis, 19 psoriatic arthropathy, 9 arthritis associated with inflammatory bowel disease, 7 non-radiographic axial spondyloarthritis, and 9 reactive arthritis. Furthermore, vitamin D deficiency (< 20 ng/ml) mainly occurred in the spring and winter seasons, with 31 and 26 patients, respectively. Conclusions: An optimization of vitamin D levels may lead to an improvement in the clinical situation of the patients, as measured by both BASDAI and DAPSA, as well as by PCR and ESR. Therefore, vitamin D monitoring and supplementation is recommended in patients with vitamin D deficiency.

RESUMEN

Videotape recordings obtained during an initial and conventional psychiatric interview were used to assess possible emotional differences in facial expressions and acoustic parameters of the voice between Borderline Personality Disorder (BPD) female patients and matched controls. The incidence of seven basic emotion expressions, emotional valence, heart rate, and vocal frequency (f0), and intensity (dB) of the discourse adjectives and interjections were determined through the application of computational software to the visual (FaceReader) and sound (PRAAT) tracks of the videotape recordings. The extensive data obtained were analyzed by three statistical strategies: linear multilevel modeling, correlation matrices, and exploratory network analysis. In comparison with healthy controls, BPD patients express a third less sadness and show a higher number of positive correlations (14 vs. 8) and a cluster of related nodes among the prosodic parameters and the facial expressions of anger, disgust, and contempt. In contrast, control subjects showed negative or null correlations between such facial expressions and prosodic parameters. It seems feasible that BPD patients restrain the facial expression of specific emotions in an attempt to achieve social acceptance. Moreover, the confluence of prosodic and facial expressions of negative emotions reflects a sympathetic activation which is opposed to the social engagement system. Such BPD imbalance reflects an emotional alteration and a dysfunctional behavioral strategy that may constitute a useful biobehavioral indicator of the severity and clinical course of the disorder. This face/voice/heart rate emotional expression assessment (EMEX) may be used in the search for reliable biobehavioral correlates of other psychopathological conditions.

RESUMEN

OBJECTIVE: Characterize homozygous familial hypercholesterolemia (HoFH) individuals from Iberoamerica. Approach and Results: In a cross-sectional retrospective evaluation 134 individuals with a HoFH phenotype, 71 adults (age 39.3±15.8 years, 38.0% males), and 63 children (age 8.8±4.0 years, 50.8% males) were studied. Genetic characterization was available in 129 (96%). The majority (91%) were true homozygotes (true HoFH, n=79, 43.0% children, 46.8% males) or compound heterozygotes (compound heterozygous familial hypercholesterolemia, n=39, 51.3% children, 46.2% males) with putative pathogenic variants in the LDLR. True HoFH due to LDLR variants had higher total (P=0.015) and LDL (low-density lipoprotein)-cholesterol (P=0.008) compared with compound heterozygous familial hypercholesterolemia. Children with true HoFH (n=34) tended to be diagnosed earlier (P=0.051) and had a greater frequency of xanthomas (P=0.016) than those with compound heterozygous familial hypercholesterolemia (n=20). Previous major cardiovascular events were present in 25 (48%) of 52 children (missing information in 2 cases), and in 43 (67%) of 64 adults with LDLR variants. Children who are true HoFH had higher frequency of major cardiovascular events (P=0.02), coronary heart (P=0.013), and aortic/supra-aortic valve diseases (P=0.022) than compound heterozygous familial hypercholesterolemia. In adults, no differences were observed in major cardiovascular events according to type of LDLR variant. From 118 subjects with LDLR variants, 76 (64%) had 2 likely pathogenic or pathogenic variants. In 89 subjects with 2 LDLR variants, those with at least one null allele were younger (P=0.003) and had a greater frequency of major cardiovascular events (P=0.038) occurring at an earlier age (P=0.001). CONCLUSIONS: There was a high frequency of cardiovascular disease even in children. Phenotype and cardiovascular complications were heterogeneous and associated with the type of molecular defect.

RESUMEN

The association of components of a low saturated fat (SFA) and of a Mediterranean diet was tested with atherosclerosis biomarkers in 190 familial hypercholesterolemia adults (FH) from Brazil (BR) and Spain (SP). Median blood LDL-C, Apolipoprotein B (apoB), and C reactive protein (hs-CRP) concentrations were higher in BR than in SP: 179.0 vs.161 mg/dL; 141 vs. 103 mg/dL; and 1.6 vs. 0.8 mg/L respectively (all p < 0.001). In BR there was lower median total fat (22.3 vs. 38.3%) and SFA (8.1 vs. 12.5%) but higher cholesterol (283.3 mg vs.188.9 mg) and carbohydrate (57.1 vs. 42.5%) consumption (all p < 0.001). Inverse associations were encountered between fibers, mono, and polyunsaturated fats and their ratios to SFA with LDL-C and ApoB (all p < 0.001). There was a direct association respectively of cholesterol with lipid biomarkers and of carbohydrates and trans-fatty acids with hs-CRP while other fats showed inverse relations with the latter (p < 0.001).

RESUMEN

Familial hypercholesterolaemia is the most common monogenic disorder associated with premature coronary artery disease. Mutations are most frequently found in the LDL receptor gene. Clinical criteria can be used to make the diagnosis; however, genetic testing will confirm the disorder and is very useful for cascade screening. Early identification and adequate treatment can improve prognosis, reducing negative clinical cardiovascular outcomes. Patients with familial hypercholesterolaemia are considered at high cardiovascular risk and the treatment target is LDL cholesterol <2.6 mmol/l or at least a 50 % reduction in LDL cholesterol. Patients require intensive treatment with statins and ezetimibe and/or colesevelam. Recently, proprotein convertase subtilisin/kexin type 9 inhibitors have been approved for the management of familial hypercholesterolaemia on top of statins.

RESUMEN

RESUMEN Objetivo: Determinar el riesgo cardiovascular y la prevalencia de factores de riesgo cardiovascular (RCV) en los pacientes con artritis reumatoide. Materiales y métodos: Estudio observacional, descriptivo y transversal, realizado en el Hospital General de Ciudad Real, entre junio de 2013 y mayo de 2014. Se realizó una analítica completa, se elaboró un perfil clínico, se calculó el SCOREm y se estratificó el RCV. Finalmente, se determinó la presencia de aterosclerosis subclínica mediante la realización de una ecografía carotídea. Resultados: 119 pacientes aceptaron participar en el estudio. Hubo una prevalencia del 73,1% de los factores de riesgo tradicionales, 6,72% había presentado un evento cardiovascular al momento del estudio, 22,68% poseía un infradiagnóstico de diabetes mellitus o nefropatía. La distribución final del RCV fue: riesgo bajo 46 (38,7%), riesgo intermedio 33 (27,7%), riesgo alto 2 (1,7%), riesgo muy alto 38 (31,9%). Conclusiones: Existe una alta prevalencia de factores de RCV y riesgo elevado infradiagnosticado en esta población. Por lo que si bien la artritis reumatoide se manifiesta de forma más aparente a nivel articular, ha de considerarse una enfermedad sistémica asociada a una mayor incidencia de eventos cardiovasculares.


ABSTRACT Objective: To determine the cardiovascular risk and the prevalence of cardiovascular risk (CVR) factors in patients with rheumatoid arthritis. Material and methods: Observational, descriptive and cross-sectional study performed in the General Hospital of Ciudad Real from June 2013 to May 2014. A complete laboratory analysis was performed, a clinical profile was prepared, the Systematic Coronary Risk Evaluation (SCOREm) was calculated, and the CVR was stratified. Finally, the presence of sub-clinical atherosclerosis was determined by performing a carotid ultrasound. Results: 119 patients accepted to participate in the study. There was a prevalence of 73.1% of traditional risk factors; 6.72% having had a cardiovascular event at the time of the study, and 22.68% had an underdiagnosis of diabetes mellitus and/or nephropathy. The final distribution of the CVR was: Low risk 46 (38.7%), intermediate risk 33 (27.7%), high risk 2 (1.7%), very high risk 38 (31.9%). Conclusions: There is a high prevalence of CVR factors and an elevated risk of underdiagnosis in the rheumatoid arthritis population. Therefore, although rheumatoid arthritis manifests itself more in the joints, it should be considered a systemic disease associated with a higher incidence of cardiovascular events.

RESUMEN

Although the International Affective Picture System (IAPS) is used to evaluate emotions (valence, arousal, and dominance evoked by a large set of photographs), bizarre images in works of art have not been assessed with the IAPS procedures. Understood here as strange, non-sense, and absurd mental contents or expressions accompanied by surprise and confusion emotions, bizarreness was assessed after healthy adult volunteers assigned this specified variable to 140 Grete Stern's photomontages overtly intended to illustrate strange, absurd, and non-sensical contents in dream reports. The images were presented to 21 Young Males (YM) and 30 Young Females (YF) who were instructed to use the IAPS Self-Assessment Manikin, along with an additional bizarre-to-normal scale, to evaluate their response to them. The valence and the bizarre-to-normal ratings showed a dissimilar pattern of distribution between genders. Ratings of scales were different, and a greater variation in scales occurred according to gender. When bizarreness was appraised, gender differences became more evident especially for YF, who rated half of the images as bizarre, and with a diminished feeling of control, while the neutral and normal images were deemed more pleased and controlled. Valence, bizarreness, and dominance formed a different component than arousal in both groups. Negative correlations between valence and dominance, and between valence and bizarreness were also found in both groups, plus a positive one for dominance and bizarreness in YF, along with curvilinear relationships among all scales. On a second experiment, 10 photomontages evaluated by YF as bizarre or as normal were administered to 18 Old Males (OM) and 28 Old Females (OF). OF's arousal showed less neutral evaluations than OM's. In OF the bizarre images evoked either more excitation or calmness than in OM. The distribution of the bizarre-to-normal scale was significantly different across the evaluations in YM, YF, OM, and OF. The use of this extended IAPS instrument to explore bizarreness and emotional variables in response to art images seems suitable and potentially valuable to characterize bizarre, absurd, or non-sensical mental states and their brain correlates.

RESUMEN

BACKGROUND AND AIMS: We aimed to assess whether elevated PCSK9 and lipoprotein (a) [Lp(a)] levels associate with coronary artery calcification (CAC), a good marker of atherosclerosis burden, in asymptomatic familial hypercholesterolemia. METHODS: We selected 161 molecularly defined FH patients treated with stable doses of statins for more than a year. CAC was measured using the Agatston method and quantified as categorical variable. Fasting plasma samples were collected and analyzed for lipids and lipoproteins. PCSK9 was measured by ELISA, Lp(a) and apolipoprotein (a) concentrations by inmunoturbidimetry and LC-MS/MS, respectively. RESULTS: Circulating PCSK9 levels were significantly reduced in patients without CAC (n = 63), compared to those with CAC (n = 99). Patients with the highest CAC scores (above 100) had the highest levels of circulating PCSK9 and Lp(a). In multivariable regression analyses, the main predictors for a positive CAC score was age and sex followed by circulating PCSK9 and Lp(a) levels. CONCLUSIONS: In statin treated asymptomatic FH patients, elevated PCSK9 and Lp(a) levels are independently associated with the presence and severity of CAC, a good predictor of coronary artery disease.

RESUMEN

En el presente trabajo se considera la investigación multidisciplinaria sobre Salvia divinorum y sus principios químicos activos con el objeto de valorar si la etnobotánica, la fitoquímica, la psicofarmacología y la neurofarmacología de esta planta psicoactiva y su principal producto químico, la salvinorina A, clarifican sus efectos mentales y sus usos adivinatorios. Esta labor científica ha trascurrido desde el registro inicial de ceremonias y creencias, ha continuado con la identificación botánica, el aislamiento de los principios químicos, la caracterización de los efectos mentales y cerebrales, las posibles aplicaciones terapéuticas y ha llegado a incurrir en el problema mente-cuerpo. Dado que el punto de partida de esta investigación es la transdisciplina de la etnofarmacología, se retoman aquí las creencias tradicionales, los usos rituales y los efectos mentales de esta menta sagrada de los indios mazatecos tal y como fueron registrados durante un proyecto de campo y laboratorio llevado a cabo entre 1973 y 1983. Un brebaje acuoso de hojas maceradas produjo un breve periodo de ligereza cefálica, disforia, sensaciones táctiles y propioceptivas exacerbadas, un sentido de despersonalización, percepción amplificada de sonidos y un aumento de la imaginación visual y auditiva, pero no verdaderas alucinaciones. Posteriormente otros autores describieron efectos similares usando cuestionarios y eventualmente fueron imputados al diterpeno salvinorina-A, pero no es posible explicar los efectos mentales sólo por la potente actividad agonista del receptor kappa a los opioides encontrada para la salvinorina; de allí el enigma psicofarmacológico. Se proponen algunos requerimientos para una clasificación de drogas que alteran cualitativamente el estado de conciencia e incluyen la activación de redes neuronales que necesariamente comprenden diversos sistemas neuroquímicos y módulos nerviosos. Para caracterizar estas redes será necesario emprender un tipo de investigación top-down, es decir el análisis de imágenes cerebrales obtenidas durante la experiencia psicoactiva analizada mediante un método narrativo, lo cual eventualmente podría permitir la exploración de efectos étnicos diferenciales. Como sucede con otras preparaciones que alteran la conciencia, una investigación rigurosa de la psicofarmacología de esta planta y su principio psicoactivo será relevante a empresas académicas tan diversas como el problema mente-cuerpo, la mejor comprensión del éxtasis chamánico y la posible generación de fármacos analgésicos, antidepresivos y moderadores de la drogadicción.


In the present paper, the multidisciplinary research on Salvia divinorum and its chemical principles is analyzed regarding whether the ethnobotany, phytochemistry, psychopharmacology, and neuropharmacology of this sacred psychoactive plant and main principle clarify its experienced effects and divinatory uses. The scientific endeavor traverses from the recorded traditional ceremonies and beliefs, continues with the botanical identification, the isolation of active molecules, the characterization of mental and neural effects, the possible therapeutic applications, and impinges upon the mind-body problem. The departure point of this search is ethnopharmacology, and therefore the traditional beliefs, ritual uses, and mental effects of this Mazatec sacred mint recorded during a 1973-1983 field research project are described. A water potion of crushed leaves produced short-lasting light-headedness, dysphoria, tactile and proprioceptive sensations, a sense of depersonalization, amplified sound perception, and increased visual and auditory imagery, but no actual hallucinations. Similar effects were described using questionnaires and are attributable to the diteprene salvinorin A, but cannot be explained solely by its specific and potent brain kappa-opioid receptor agonist activity. Some requirements for a feasible classification and mechanism of action of consciousness-altering products are proposed and include the activation of neural networks comprising several neurochemical systems. Top-down analyses should be undertaken in order to characterize such neural networks and eventually allowing to explore the differential ethnic effects. As is the case for other consciousness-altering preparations, a careful and encompassing research on this plant and principle can be consequential to academic undertakings ranging from the mind-body problem and a better understanding of shamanic ecstasy, to the potential generation of analgesic, antidepressant, and drug-abuse attenuating products.

RESUMEN

The present experiment was designed to test if sustained attention directed to the spontaneous sensations of the right or left thumb in the absence of any external stimuli is able to activate corresponding somatosensory brain areas. After verifying in 34 healthy volunteers that external touch stimuli to either thumb effectively activate brain contralateral somatosensory areas, and after subtracting attention mechanisms employed in both touch and spontaneous-sensation conditions, fMRI evidence was obtained that the primary somatosensory cortex (specifically left BA 3a/3b) becomes active when an individual is required to attend to the spontaneous sensations of either thumb in the absence of external stimuli. In addition, the left superior parietal cortex, anterior cingulate gyrus, insula, motor and premotor cortex, left dorsolateral prefrontal cortex, Broca's area, and occipital cortices were activated. Moreover, attention to spontaneous-sensations revealed an increased connectivity between BA 3a/3b, superior frontal gyrus (BA 9) and anterior cingulate cortex (BA 32), probably allowing top-down activations of primary somatosensory cortex. We conclude that specific primary somatosensory areas in conjunction with other left parieto-frontal areas are involved in processing proprioceptive and interoceptive bodily information that underlies own body-representations and that these networks and cognitive functions can be modulated by top-down attentional processes.

RESUMEN

RESUMEN Antecedentes: La reanimación en el paro cardiaco con isquemia global logra restablecer la circulación espontánea en algunos pacientes; sin embargo, la sobrevida depende de muchos factores que explican el síndrome posparo cardiaco. El entendimiento y el control de estos factores durante la última década han logrado mejorar el pronóstico en un subgrupo de pacientes. Objetivo: Describir la fisiopatología y el manejo actual del síndrome posparo cardiaco. Metodología: Revisión narrativa de la literatura a través de las bases electrónicas de Medline vía PubMed y Ensayos Clínicos usando los términos MeSH Cardiac arrest -Cardiopulmonary Resuscitation y (el término no MeSH) Post cardiac arrest syndrome. Resultados: Los estudios clínicos han establecido una serie de protocolos y guías de manejo basadas en objetivos terapéuticos con tasas de sobrevida que superan el 50% de las víctimas de paro cardiaco. Conclusiones: Actualmente el manejo de este síndrome ha fortalecido el último eslabón de la cadena de supervivencia al estandarizar la evaluación y la selección de víctimas de paro cardiaco con un protocolo de hipotermia terapéutica e intervención coronaria percutánea precoz.


ABSTRACT Background: Resuscitation from cardiac arrest with global ischemia restores spontaneous circulation in some patients; however, survival depends on many factors associated with post cardiac arrest syndrome. During the last ten years, the understanding and control of these factors have improved the prognosis in a subgroup of patients. Objective: To describe the pathophysiology and current management of the post cardiac arrest syndrome (PCAS). Methodology: Narrative review of the literature using Medline via PubMed and Clinical Trials, using the terms MeSH cardiac arrest - Cardiopulmonary Resuscitation and (no term MeSH) Post cardiac arrest syndrome. Results: Clinical trials have established a set of management protocols and guidelines based on therapeutic objectives with survival rates exceeding 50% of the cardiac arrest victims. Conclusions: The management of this syndrome has actually strengthened the last link in the survival chain by standardizing the evaluation and selection of cardiac arrest victims via a therapeutic hypothermia protocol and early percutaneous coronary intervention.

RESUMEN

Some types of first-person narrations of mental processes that constitute phenomenological accounts and texts, such as internal monolog statements, epitomize the best expressions and representations of human consciousness available and therefore may be used to model phenomenological streams of consciousness. The type of autonomous monolog in which an author or narrator declares actual mental processes in a think aloud manner seems particularly suitable for modeling streams of consciousness. A narrative method to extract and depict conscious processes, operations, contents, and states from an acceptable phenomenological text would require three subsequent steps: operational criteria for producing and/or selecting a phenomenological text, a system for detecting text items that are indicative of conscious contents and processes, and a procedure for representing such items in formal dynamic system devices such as Petri nets. The requirements and restrictions of each of these steps are presented, analyzed, and applied to phenomenological texts in the following manner: (1) the relevance of introspective language and narrative analyses to consciousness research and the idea that specific narratives are of paramount interest for such investigation is justified; (2) some of the obstacles and constraints to attain plausible consciousness inferences from narrative texts and the methodological requirements to extract and depict items relevant to consciousness contents and operations from a suitable phenomenological text are examined; (3) a preliminary exercise of the proposed method is used to analyze and chart a classical interior monolog excerpted from James Joyce's Ulysses, a masterpiece of the stream-of-consciousness literary technique and, finally, (4) an inter-subjective evaluation for inter-observer agreement of mental attributions of another phenomenological text (an excerpt from the Intimate Journal of Miguel de Unamuno) is presented using some mathematical tools.
