Inpatient Skin-to-skin Care Predicts 12-Month Neurodevelopmental Outcomes in Very Preterm Infants.

OBJECTIVE: To examine the relationship between inpatient skin-to-skin care rates and neurodevelopmental scores measured at 12 months in very preterm (VPT) infants. STUDY DESIGN: From a retrospective review of medical records of 181 VPT infants (<32 weeks gestational age [GA] at birth), we derived skin-to-skin care rate, ie, total minutes of skin-to-skin care each infant received over the number of days of hospital stay. We used scores on the Capute Scales from routine follow-up assessments at 12 months to measure neurodevelopmental outcomes. RESULTS: Families averaged approximately 17 minutes/day of skin-to-skin care (2 days/week, 70 minutes/session), although there was substantial variability. Variation in skin-to-skin rate was positively associated with outcomes at 12 months corrected age (r = 0.25, P < .001). Skin-to-skin rate significantly predicted 6.2% unique variance in 12-month neurodevelopmental outcomes, after adjusting for GA, socioeconomic status (SES), health acuity, and visitation frequency. A 20-minute increase in skin-to-skin care per day was associated with a 10-point increase (0.67 SDs) in neurodevelopmental outcomes at 12 months. GA and infant health acuity did not moderate these relations. CONCLUSION: VPT infants who experienced more skin-to-skin care during hospitalization demonstrated higher scores on 12-month neurodevelopmental assessments. Results provide evidence that skin-to-skin care confers extended benefits to VPT infants through the first year of life. Skin-to-skin care offers promise as a family-centered intervention designed to promote positive developmental outcomes in at-risk infants.

Osseointegration of Dental Implants in Patients with Congenital and Degenerative Bone Disorders: A Literature Review.

Aims and Objectives: The aim of this study was to describe the mechanism of dental implants osseointegration in patients with congenital and degenerative genetic bone disorders. Materials and Methods: A PubMed and Scopus documents search was carried out between November 2021 in the, using words such as "osseointegration," "degenerative disease," "congenital disease," and "dental implants." Results: The thirteen articles selected dealt with dental implants osseointegration in patients with congenital and degenerative bone disorders. The influence and repercussion of these diseases on the bone system, as well as the osseointegration process were described from healing to bone remodeling. In addition, certain articles described some considerations to improve the osseointegration process in patients suffering from these types of conditions. Conclusions: Within the limitations of this literature review we can conclude that osseointegration in patients with ectodermal dysplasia and osteoporosis could be achieved. However, the planning process for dental implant placement in these patients should be more meticulous and individualized considering the degree of tissue involvement as well as the patient's age and skeletal development compared to systemically healthy patients.

La hipertensión arterial como causa de muerte: causa básica vs causas múltiples. Cuba, 2013-2019 / Arterial hypertension as a cause of death: basic cause vs multiple causes. Cuba, 2013-2019

Introducción: Las tasas de mortalidad "por" hipertensión arterial subestiman el impacto de esta causa en la mortalidad. Objetivo: Determinar el cambio de la contribución de la hipertensión arterial como causa de muerte, al involucrar todas sus menciones en el certificado de defunción en Cuba en el periodo 2013-2019. Material y Métodos: Se realizó un estudio observacional descriptivo de las defunciones ocurridas en Cuba entre enero de 2013 y diciembre de 2019. Se calcularon las Tasas de Mortalidad "por" (causa básica) y "con" hipertensión arterial (causas múltiples). Además, se determinaron las causas básicas más asociadas a la mención de esta afección. Resultados: Los riesgos de morir "por" y "con" hipertensión arterial evidencian un ascenso. El segundo es, como promedio, cuatro veces mayor que el primero; lo que significa que el análisis de mortalidad "por· HTA continúa infravalorando el papel de esta afección dentro de los procesos que causan muerte. Ambos riesgos son mayores para hombres y para los adultos de 85 años y más. Como promedio, en 15,7 por ciento de las defunciones se mencionó a la HTA en alguna de las partes del certificado; sin embargo, solo en 3,8 por ciento fue declarada como causa básica. Las enfermedades cerebrovasculares y las del corazón son las dos causas básicas en las que la HTA es más frecuentemente causa asociada. Conclusiones: La contribución de la hipertensión arterial a la mortalidad es mayor a lo que traduce el análisis tradicional. Disponer de estimaciones de causas múltiples fortalecería la planificación en salud y potenciaría los análisis de carga de enfermedad(AU)

Introduction: Mortality rates "due to" arterial hypertension underestimate the impact of this cause on mortality. Objective: To determine the change in the contribution of arterial hypertension to the cause of death, by analyzing all its mentions in the death certificates in Cuba in the period 2013-2019. Material and Methods: A descriptive observational study of deaths that occurred in Cuba between January 2013 and December 2019 was carried out. Mortality rates "due to" (basic cause) and "with" arterial hypertension (multiple causes) were calculated. In addition, the most common underlying causes associated with the mention of this condition were determined. Results: The risks of dying "due to" and "with" arterial hypertension show an increase. The second risk is, on average, four times higher than the first one, which means that the analysis of mortality "due to" arterial hypertension continues to underestimate the role of this condition within the processes causing death. Both risks are higher for men and adults aged 85 years and older. On average, arterial hypertension was mentioned in some parts of the certificates in 15,7 percent of the deaths registered during the period; however, it was declared as the basic cause only in 3,8 percent of them. Cerebrovascular and heart diseases are the two underlying causes in which arterial hypertension is the most frequently associated cause. Conclusions: The contribution of arterial hypertension to mortality is greater than that identified in the traditional analysis. Having estimates of multiple causes would strengthen health planning and enhance the analyses of disease burden(AU)

A new diterpene and bioactivities of labdanes isolated from Buddleja marrubiifolia.

The new labdane [(3R*,4aR*,7S*,10aS*,10bR*)-3-ethenyl-3,4a,7,10a-tetramethyl-dodecahydro-1H-naphtho-[2,1-b]-pyran-7-yl]-methylbenzoate together with other 7 labdanes were isolated from the aerial parts of Buddleja marrubiifolia. Compound structures were elucidated by spectroscopic methods. Some compounds showed moderate to weak antimicrobial activity towards a panel of bacterial and fungal pathogens. In addition, trans-biformene (2) and ribenol acetate (8) showed to be highly cytotoxic with LC50 < 1 µg/mL, the other compounds showed moderate cytotoxic effect with a LC50 range of 6.008-15.26 µg/mL. For all isolated compounds, no inflammatory response was observed.

Key factors associated with uncontrolled asthma - the Asthma Control in Latin America Study.

Objective: This study aimed to estimate asthma control at specialist treatment centers in four Latin American countries and assess factors influencing poor asthma control.Methods: Patients aged ≥12 years with an asthma diagnosis and asthma medication prescription, followed at outpatient specialist centers in Argentina, Chile, Colombia, and Mexico, were included. The study received all applicable ethical approvals. The Asthma Control Test (ACT) was used to classify patients as having controlled (ACT 20-25) or uncontrolled (ACT ≤19) asthma. Frequency and statistical tests were used to assess the association between hospital admissions/exacerbations/emergency department (ED) visits and uncontrolled asthma; multivariate logistic regression was used to assess the association of uncontrolled asthma with clinical/demographic variables.Results: A total of 594 patients were included. Overall controlled-asthma prevalence was 43.4% (95% confidence interval [CI]: 39.0, 47.4). Patients with uncontrolled asthma were more likely to be women (adjusted odds ratio [aOR]: 1.85; p = 0.003), non-white (aOR: 2.14; p < 0.001), obese (aOR: 1.71; p = 0.036), to have a low monthly family income (aOR: 1.75; p = 0.004), to have severe asthma (aOR:1.59; p = 0.26), and, compared with patients with controlled asthma, to have a higher likelihood of asthma exacerbations (34.5% vs. 15.9%; p < 0.001), hospital admissions (6.9% vs. 3.1%; p = 0.042), and ED visits (34.5% vs. 15.9%; p < 0.001) due to asthma.Conclusions: Even in specialist ambulatory services, fewer than half of patients were classified as having controlled asthma. The proportion of uncontrolled patients varied according to clinical and demographic variables.

Integrating expert knowledge and ecological niche models to estimate Mexican primates' distribution.

Ecological niche modeling is used to estimate species distributions based on occurrence records and environmental variables, but it seldom includes explicit biotic or historical factors that are important in determining the distribution of species. Expert knowledge can provide additional valuable information regarding ecological or historical attributes of species, but the influence of integrating this information in the modeling process has been poorly explored. Here, we integrated expert knowledge in different stages of the niche modeling process to improve the representation of the actual geographic distributions of Mexican primates (Ateles geoffroyi, Alouatta pigra, and A. palliata mexicana). We designed an elicitation process to acquire information from experts and such information was integrated by an iterative process that consisted of reviews of input data by experts, production of ecological niche models (ENMs), and evaluation of model outputs to provide feedback. We built ENMs using the maximum entropy algorithm along with a dataset of occurrence records gathered from a public source and records provided by the experts. Models without expert knowledge were also built for comparison, and both models, with and without expert knowledge, were evaluated using four validation metrics that provide a measure of accuracy for presence-absence predictions (specificity, sensitivity, kappa, true skill statistic). Integrating expert knowledge to build ENMs produced better results for potential distributions than models without expert knowledge, but a much greater improvement in the transition from potential to realized geographic distributions by reducing overprediction, resulting in better representations of the actual geographic distributions of species. Furthermore, with the combination of niche models and expert knowledge we were able to identify an area of sympatry between A. palliata mexicana and A. pigra. We argue that the inclusion of expert knowledge at different stages in the construction of niche models in an explicit and systematic fashion is a recommended practice as it produces overall positive results for representing realized species distributions.

Effects of castration on androgen receptors and gonadotropins in the pituitary of adult male viscachas.

The aims of the present study were to determine whether castration results in quantitative immunohistochemical changes in androgen receptors (AR), LH-immunoreactive (IR) cells and FSH-IR cells, and to analyse the colocalisation of AR and gonadotropins in the pituitary pars distalis (PD) of viscachas. Pituitaries were processed for light and electron microscopy. AR-IR, LH-IR and FSH-IR cells were detected by immunohistochemistry. In morphometric studies, the percentage of AR-IR, LH-IR, FSH-IR, LH-IR/AR-IR and FSH-IR/AR-IR cells was determined. In intact viscachas, AR were distributed throughout the PD; they were numerous at the caudal end, with intense immunostaining. LH-IR cells and FSH-IR cells were found mainly in the ventral region and at the rostral end of the PD. Approximately 45%-66% of LH-IR cells and 49%-57% of FSH-IR cells expressed AR in the different zones of the PD. In castrated viscachas, there was a significant decrease in the percentage of AR-IR, LH-IR, FSH-IR, and FSH-IR/AR-IR cells. Some pituitary cells from castrated viscachas also exhibited ultrastructural changes. These results provide morphological evidence that gonadal androgens are directly related to the immunolabelling of AR, LH and FSH. Moreover, the colocalisation of AR and FSH is most affected by castration, suggesting the existence of a subpopulation of gonadotrophs with different regulatory mechanisms for hormonal synthesis, storage and secretion.

El extracto acuoso de ruta graveolens del norte de méxico causa apoptosis y muestra efecto antiproliferativo sobre el hígado de rata wistar: evidencia morfológica / Aqueous extract of ruta graveolens from the north of mexico causes apoptosis and shows antiproliferative effect on the liver of wistar rat: morphological evidence

Ruta graveolens es una planta nativa del Mediterráneo Oriental y del área Sur Occidental de Asia, de esta planta se han aislado más de 120 compuestos químicos. En un estudio previo en nuestro laboratorio se observó que un extracto acuoso de R. graveolens causó necrosis y alteraciones morfológicas sugestivas de apoptosis sobre el hígado de rata Wistar. El objetivo del presente estudio, fue evaluar la inducción de apoptosis y el posible efecto antiproliferativo in vivo de un extracto acuso de R. graveolens del norte de México, mediante métodos inmunohistoquímicos. Se utilizaron 25 ratas Wistar y se dividieron en 5 grupos (n=5). El grupo 1 correspondió al grupo control negativo, el grupo 2 o control positivo se trató con 100 mg de dexametasona/kg/día. Los grupos 3 y 4 se trataron con 30 y 100 mg de extracto de R. graveolens/kg/día respectivamente. Al grupo 5 se le administraron 100 mg de dexametasona/kg/día combinados con 100 mg de extracto de R. graveolens/kg/día. Las administraciones se realizaron vía intraperitoneal por tres días. Los animales se sacrificaron por dislocación cervical, y se tomaron muestras de hígado que se fijaron en formalina, posteriormente se incluyeron en bloques de parafina. Se obtuvieron cortes histológicos que se tiñeron con el método tricrómico de Masson. También se realizaron pruebas inmunohistoquímicas de TUNEL, anti-bcl-2 y anti-PCNA; además de un estudio morfométrico. Los resultados demuestran por primera vez el potencial apoptósico y antiproliferativo del extracto acuoso de R. graveolens del norte de México, sobre el hígado de rata Wistar. Se sugiere la posibilidad de emplear dosis menores a las administradas en este estudio del extracto acuoso de R. graveolens, para investigar su potencial uso como agente antineoplásico en estudios in vitro con líneas celulares tumorales e/o implantadas en modelos murinos de cáncer.

Ruta graveolens, is a native plant of the Eastern Mediterranean and the South Western area of Asia. From this plant, more than 120 chemical compounds have been isolated. In a previous study in our laboratory, we observed that an aqueous extract of R. graveolens, caused necrosis and morphological alterations suggestive of apoptosis on the liver of Wistar rats. The objective of this study, was to evaluate the induction of apoptosis and a possible antiproliferative effect in vivo of an aqueous extract of R. graveolens from the north of Mexico, by immunohistochemical methods. 25 Wistar rats were used and divided into 5 groups (n= 5). Group 1 corresponded to negative control group, group 2 or positive control was treated with 100 mg of dexamethasone/kg/day. Groups 3 and 4 were treated with 30 and 100 mg of extract of R. graveolens/kg/day respectively. Group 5 received the administration of 100 mg of dexamethasone/kg/day combined with 100 mg of extract of R. graveolens/kg/day. The administrations were by intraperitoneal via for three days. The animals were sacrificed by cervical dislocation, liver samples were taken, fixed in formalin and then samples were embedded in paraffin blocks. Histological sections were obtained and stained with Masson trichrome method. Immunohistochemical assays of TUNEL, anti-bcl-2, and anti-PCNA were performed. Also a morphometric study was carried out. Results show for the first time the potential apoptotic and antiproliferative effect of an aqueous extract of R. graveolens from the north of Mexico on the liver of Wistar rats. This suggests the use of lower doses of the extract of R. graveolens, to investigate its potential use as an antineoplastic agent, in studies in vitro with tumor cell lines and/or implanted in murine models of cancer.

Efecto tóxico del extracto acuoso de ruta graveolens del norte de mexico sobre el hígado de rata wistar / Toxic effect of aqueous extract of ruta graveolens from the north of mexico on the liver of wistar rat

A Ruta graveolens se le atribuyen propiedades benéficas en medicina tradicional, sin embargo se ha demostrado que también puede producir efectos adversos. A la fecha no existe evidencia que ratifique que R. graveolens es totalmente inofensiva, por este motivo el objetivo de este estudio fue determinar el efecto tóxico del extracto acuoso de las hojas de esta especie vegetal en hígado de rata. Se utilizaron 25 ratas Wistar y se dividieron en 5 grupos (n=5). El grupo 1 correspondió al grupo control negativo, el grupo 2 o control positivo se trató con 100 mg de dexametasona/kg/día. Los grupos 3 y 4 se trataron con 30 y 100 mg de extracto de R. graveolens respectivamente. Al grupo 5 se le administraron 100 mg de dexametasona/kg/día combinado con 100 mg de extracto de R. graveolens/kg/día. Las administraciones se realizaron vía intraperitoneal por tres días. Los animales se sacrificaron por dislocación cervical. Las muestras de hígado se fijaron en formalina y posteriormente se incluyeron en parafina. Se obtuvieron cortes histológicos de 5 micras de grosor que se tiñeron con Hematoxilina-Eosina para la evaluación histológica con microscopia de luz. Los resultados demuestran por primera vez que la exposición al extracto acuoso de R. graveolens induce alteraciones morfológicas en el hígado de ratas Wistar. Estas alteraciones se observaron de manera leve en el grupo 3 y se incrementaron en el grupo 4. Destacó que el mayor daño se observó en el grupo 5. Se concluye que el extracto acuoso de R. graveolens resultó tóxico, sin embargo es necesario realizar estudios adicionales con el fin de caracterizar otros efectos toxicológicos que soporten el riesgo del uso de R. graveolens en medicina tradicional a largo plazo.

In traditional medicine, beneficial properties are attributed to Ruta graveolens, but it has been shown that it can also cause side effects. Because there is no evidence that ratifies that R. graveolens is totally harmless. The aim of this study was to determine the toxic effect of aqueous extract of the leaves of this plant in rat liver. 25 Wistar rats were used and divided into 5 groups (n = 5). Group 1 corresponded to the negative control group; group 2 or positive control was treated with 100 mg of dexamethasone/kg/day. Groups 3 and 4 were treated with 30 and 100 mg of extract of R. graveolens respectively. Group 5 was treated with 100 mg dexamethasone/kg/ day in combination with 100 mg of extract of R. graveolens/kg/day. Administrations were performed intraperitoneally for three days. All animals were sacrificed by cervical dislocation. Liver samples were fixed in formalin and then embedded in paraffin. Histological sections were obtained from 5 microns thick and stained with hematoxylin-eosin for histological evaluation by light microscopy. The results demonstrate for the first time that exposure to aqueous extract of R. graveolens induces morphological changes in the liver of Wistar rats. These alterations were observed slightly in group 3. Alterations increased in group 4. Highest damage was observed in group 5. The aqueous extract of R. graveolens was toxic; furthermore additional studies are needed to characterize other toxicological effects that support the risk of use of R. graveolens in traditional medicine in a long term.

Diversidad de mamíferos en la cuenca media del río Tambopata, Puno, Perú / Mammal diversity in the middle basin of the river Tambopata, Puno, Peru

El presente trabajo documenta la diversidad de mamíferos en la cuenca media del río Tambopata, uno de los vacíos de información más importantes del Perú. Se evaluaron cinco localidades en Puno (San Fermín 850 m, Curva Alegre 950 m, Challohuma 1200 m, Yanahuaya 1600 m y Yanacocha 1985 m). El esfuerzo de captura fue de 7072 trampas noche y 201 redes noche. Se registraron 76 especies en el área de estudio de los cuales 16 especies estaban bajo alguna categoría de conservación. Los murciélagos y los roedores fueron los órdenes más diversos (67,5%). Los índices de diversidad (H’ y Simpson) de los mamíferos menores muestran una correlación negativa y moderada con la altitud. La Abundancia Relativa (AR) de los murciélagos tuvo una fuerte correlación negativa respecto de la altitud, mientras que los mamíferos pequeños terrestres una fuerte correlación positiva. Los marsupiales Marmosa (Micoureus) demerarae, Marmosops bishopi y Marmosops impavidus; el roedor Neacomys musseri; y los murciélagos Platyrrhinus albericoi, P. masu, P. nigellus, Eumops auripendulus y Cormura brevirostris son los primeros registros para el departamento de Puno. Las especies de roedores Oxymycterus juliacae y Akodon baliolus son consideradas validas. Las especies Sturnira lilium y Akodon baliolus fueron las que obtuvieron una mayor AR. Nuestros resultados, adicionados a literatura previa, indican que la cuenca del río Tambopata alberga actualmente 141 especies de mamíferos. Finalmente, recomendamos la extensión de la zona sur de la Zona de Amortiguamiento del PNBS hasta los bosques montanos de Yanacocha, para la protección de la fauna de la cuenca media del río Tambopata.

This study documents the mammalian diversity in the Tambopata River middle basin, one of the most important information gaps in Peru. Five sites were evaluated in Puno (San Fermín 850 m, Curva Alegre 950 m, Challohuma 1200 m, Yanahuaya 1600 m, and Yanacocha 1985 m). The trapping effort was 7072 trap-nights and 201 mistnet-nights. 76 species were recorded in the study area, including 16 species under some conservation’s category. Bats and rodents were the most diverse orders (67.5%). The diversity indices of Shannon-Wiener and Simpson for small mammals show a moderate and mild negative correlation with elevation, respectively. Meanwhile the altitude is negatively correlated with the relative abundance (RA) of bats, and positively with the RA of non-volant mammals. The marsupials Marmosa (Micoureus) demerarae, Marmosops bishopi and Marmosops impavidus; the rodent Neacomys musseri, and bats Platyrrhinus albericoi, P. masu, P. nigellus, Eumops auripendulus and Cormura brevirostris are first records for the department of Puno. Akodon baliolusand Oxymycterus juliacae are considered valid species. The species Sturnira lilium and Akodon baliolus were those with the highest RA. Our records, added to published and unpublished data, indicate that the Río Tambopata watershed is habitat of 141 species of mammals. Finally, we recommend the extension of the southern part of the buffer zone of the PNBS to include the montane forests of Yanacocha, to protect the unique middleelevation fauna of the Río Tambopata watershed.

[Reproduction of the spiny puffer, Diodon holocanthus (Pisces: Diodontidae) in the continental shelf of Mexican Central Pacific]. / Reproducción del pez erizo, Diodon holocanthus (Pisces: Diodontidae) en la plataforma continental del Pacífico Central Mexicano.

Diodon holocanthus is an important economic and ecological species of the demersal fish community, caught as bycatch from local shrimp fishery. The reproductive biology of this long-spine porcupinefish has not yet been described, and reproductive season, the sex ratio, length distribution, length at first gonad maturity, and the gonad macro and microscopic features are described. A total of 400 organisms, ranging from 5.0 to 40.3 cm (average 18.4 cm) total length, were caught from the continental shelf of the Central Mexican Pacific, from December 1995 and December 1998. Sex ratio was 1:0.86 females to males (n = 253). The length at which 50% of the individuals showed maturing gonads was 19.7 cm for females and 20.1 cm for males. Length of the smallest organism with ripe gonads was 12.2 cm for females and 13 cm for males. Four gonadal maturation stages were found in both sexes, and five oocyte development phases were identified. The oocyte development pattern is of asynchronous type, which means the species can reproduce several times a year. Testicle development is lobular type, as in most teleost fishes. Monthly mean values of the gonad-somatic index suggest the reproduction activity peaks in June, and September-December.

Diodon holocanthus es una especie con cierta importancia comercial y ecológica en la comunidad de peces que forma la fauna de acompañamiento del camarón en la plataforma continental del Pacífico central Mexicano, y de la cual no se conocen aspectos reproductivos. Por lo cual se obtuvieron el periodo de reproducción, la descripción macro y microscópica de las gónadas, además de variables poblacionales como: distribución de tallas, proporción sexual y talla de madurez. En total se capturaron alrededor de 400 organismos, los cuales presentaron una talla mínima de 5.0cm, máxima de 40.3cm y promedio de 18.4cm, y fueron capturados en la plataforma continental en el Pacífico central Mexicano, desde diciembre de 1995 a diciembre de 1998. La proporción sexual fue de 1:0.86 hembras por machos (n=253). La talla a la cual el 50% de individuos presentó gónadas maduras fue 19.7cm en las hembras y 20.1cm en los machos. Los organismos con las menores tallas que presentaron gónadas en fase de maduración midieron 12.2cm (hembras) y 13cm (machos). En ambos sexos el desarrollo de la gónada se determinó con base en una escala de maduración de cuatro estadios. En el proceso de maduración de los ovocitos se identificaron cinco fases de desarrollo. El patrón de desarrollo de los ovocitos es de tipo asincrónico, lo que significa que la especie se puede reproducir varias veces al año. El desarrollo del testículo es de tipo lobular como en la mayoría de los peces teleósteos. El índice gonadosomático sugiere que el periodo de reproducción se concentra en los meses de junio, y de septiembre a diciembre.

Corporalidad y uso de drogas: estudio de caso de la experiencia subjetiva del cuerpo / Bodily experience and drug abuse: a case study of the subjective experience of the body

Estudio de caso que explora la experiencia subjetiva del cuerpo en la trayectoria con el uso de drogas a través del relato de vida. Se utilizó la entrevista abierta bajo los supuestos metodológicos del relato autobiográfico. Se propuso al participante "Hablar de sí mismo y contar su experiencia con el uso de drogas". La estrategia analítica se diseñó con base en la propuesta de Barthes (1990) para el análisis estructural de los relatos. Los resultados muestran que en el relato emerge una subjetividad que articula modos de haber sido y ser cuerpo como instancias constitutivas de la existencia. Desde el punto de vista de la corporalidad, la trayectoria con el uso de drogas deviene en una relación de saber-poder con el propio cuerpo, donde la experiencia subjetiva se entreteje en una red de controles y normas sociales. El análisis del cuerpo como experiencia enriquece la comprensión de prácticas como el uso de drogas.

This case study explores the subjective experiences of the body as a narration that gives meaning to reality as a result of drug abuse. It uses the open interview technique based on the method of autobiographic narrative. During the interview the participant was asked to "Speak about himself and tell of his experience with consumption of illegal drugs." This analytic strategy is based on some elements proposed by Barthes (1990) for the structural analysis of narratives. The results show that in the process of these narrations subjectivity emerges, that articulates the individual's own existence through experiences of having been and of being a body. From this corporal perspective, the process of drug use generates a relationship of power with one's own body, whereby the subjective experience is woven into a network of social controls and norms. Analytic study of the body as a subjective experience helps understand drug abuse.

From this corporal perspective, the process of drug use generates a relationship of power with one's own body, whereby the subjective experience is woven into a network of social controls and norms. Analytic study of the body as a subjective experience helps understand drug abuse.(AU)
