Valorisation of grape stem as an alternative ingredient in rabbit feed.

Grape stem is a winery by-product that it is currently disposed as waste or at best as soil conditioner. However, it is rich in fibres and polyphenols which makes it interesting for animal feeding. In this regard, rabbit farming emerges as a target livestock farming since fibre content is essential in rabbit's diets for preventing digestive troubles and polyphenols are associated with improved performances in animals due to their antimicrobial and antioxidant activities. This study aims to assess the suitability of a grape stem-based ingredient for rabbit feeding. The stem was dried using flash drying technology to prevent rapid spoilage and stabilise the ingredient. Then, its nutritional value was evaluated resulting in a high fibre (>40%) and polyphenol (>6%) content ingredient with antioxidant and antimicrobial activity against Staphylococcus aureus. A feed efficiency trial was conducted and inclusion rates of up to 10% of grape stem-based ingredient did not affect animals' mortality, average daily feed intake, daily gain or feed conversion ratio. In conclusion, grape stem-based ingredient arises as a secondary feedstuff for cuniculture reducing the dependence on other fibre sources, such as cereals or sunflower hulls. This could also contribute to reduce the environmental footprint of the wine sector by giving a second life to an existing waste, while generating a new activity based on circular economy.

Implementation of a Comprehensive and Personalised Approach for Older People with Psychosocial Frailty in Valencia (Spain): Study Protocol for a Pre-Post Controlled Trial.

With ageing, the risk of frailty increases, becoming a common condition that exposes older people to an increased risk of multiple adverse health outcomes. In Valencia (Spain), the ValueCare project develops and applies a value-based care approach that addresses the multidimensional nature of frailty by implementing integrated and personalized care to tackle psychosocial frailty. A pre-post controlled design with a baseline measurement at inclusion, at the end of implementation and a follow-up measurement after 6 months of intervention. In Valencia (Spain), 120 participants over 65 years of age are recruited from primary care centres to receive the ValueCare comprehensive and personalised care plan according to the results and are compared with 120 participants receiving "usual care". An assessment questionnaire is designed using validated instruments, and a personalised care plan is developed specifically for each participant based on the results obtained. The study protocol has been registered under the ISRCTN registration number ISRCTN25089186. Addressing frailty as a multidimensional and multifactorial risk condition requires the development and implementation of comprehensive assessments and care. In this context, this study will provide new insights into the feasibility and effectiveness of a value-based methodology for integrated care supported by ICT for older people experiencing frailty.

Value-Based Healthcare Delivery: A Scoping Review.

Healthcare systems are transforming from the traditional volume-based model of healthcare to a value-based model of healthcare. Value generation in healthcare is about emphasising the health outcomes achieved by patients and organisations while maintaining an optimal relationship with costs. This scoping review aimed to identify the key elements and outcomes of implementing value-based healthcare (VBHC). The review process included studies published from 2013 to 2023 in four different databases (SpringerLink, PubMed, ProQuest and Scopus). Of the 2801 articles retrieved from the searches, 12 met the study's inclusion criteria. A total of 11 studies referred to value as the relationship between the outcomes achieved by patients and the costs of achieving those outcomes. Most of the studies highlighted the presence of leadership, the organisation of care into integrated care units, the identification and standardisation of outcome measures that generate value for the patient, and the inclusion of the patient perspective as the most prominent key elements for optimal VBHC implementation. Furthermore, some benefits were identified from VBHC implementation, which could shed light for future implementation actions. Therefore, the VBHC model is a promising approach that may contribute to an improvement in the efficiency and sustainability of healthcare.

Psychosocial Impact of Infertility Diagnosis and Conformity to Gender Norms on the Quality of Life of Infertile Spanish Couples.

Epidemiological data show that human reproductive disorders are a common problem worldwide, affecting almost one in six people of reproductive age. As a result, infertility has been identified by the World Health Organization as a public health disease. Reproductive problems can take a heavy toll on the psychosocial well-being of couples suffering from infertility. This is especially true for women, who tend to be the ones who undergo the most treatment. The main objective of the present study is to find out whether a sex-based infertility diagnosis influences the quality of life of couples with infertility. Also, we aim to find out whether the degree of adherence to gender norms influences their quality of life. A cross-sectional study was conducted using the Fertility Quality of Life Questionnaire (FertiQoL) and the Conformity to Feminine and Masculine Norms Inventories in a sample of 219 infertile Spanish couples (438 participants). The results show that, in all cases, regardless of the degree of conformity to gender norms and whether the infertility diagnosis was of female or male origin, women have lower scores on the self-perceived quality of life. This suggests that being female is already a psychosocial risk factor when assessing the psychosocial consequences of infertility.

Self-efficacy as a mediator between frailty and falls among community-dwelling older citizens.

Frailty is one of the most challenging issues among older adults, and the relationship between frailty and falls has already been assessed numerous times in literature. In the present study, we explored the mediating role of self-efficacy related to falls (FSe) in the relationship between frailty and fall risk. In a cross-sectional design, 1080 community-dwelling older adults from Rotterdam (Netherlands) and Valencia (Spain) completed a questionnaire and data were then analyzed via mediation analysis using a bootstrapping approach. Results show that higher frailty is associated with higher fall incidence, and higher FSe is a partial mediator of this association, with a confidence interval for the indirect effect of 0.131-0.247. Moreover, results showed gender differences in FSe levels; women had lower FSe scores. Deepening research on the construct of FSe may give potential explanations that account for the emerged gender differences, and it could be more targeted in fall prevention programs.

Factorial structure of quality of life, satisfaction with caregiving and caregiver burden in palliative care: A systematic review.

AIM: The aim of this research is to identify the main approaches and domains of palliative care quality assessment through three questionnaires used for this purpose. DESIGN: Systematic review. METHODS: The proposed analysis process consists of three stages from 2000 to 2020: (i) massive literature search, (ii) text mining and (iii) systematic reviews carried out on the QLQ C30, Zarit Burden Interview and FAMCARE questionnaires. The Preferred Reporting Items for Systematic Reviews (PRISMA-P) have guided our research. RESULTS: Sixteen papers were included in our study. The main findings have been summarised using a descriptive narrative synthesis approach. Systematic reviews evidenced that such tools present variable factor structures or latent domains. The results obtained are generally representative of the evidence supporting the factor structure of the QLQ-C30 in the general cancer population. The factor structure of the Zarit Burden Interview remains ambiguous, although the idea of a unifactorial structure predominates. In the case of FAMCARE, most of the factor structures differ from the initial proposal of Kristjanson. The categorisation of the main subjective assessment approaches could be useful for the construction of a coherent system of indicators to be used in nursing practice. For its part, the variability in the latent dimensionality of the questionnaires analysed could be due to: (i) the characteristics of the sample, (ii) the population studied, (iii) cross-cultural variability, (iv) the design of the questionnaire and (v) the analysis techniques employed.

Transcription regulation by long non-coding RNAs: mechanisms and disease relevance.

Long non-coding RNAs (lncRNAs) outnumber protein-coding transcripts, but their functions remain largely unknown. In this Review, we discuss the emerging roles of lncRNAs in the control of gene transcription. Some of the best characterized lncRNAs have essential transcription cis-regulatory functions that cannot be easily accomplished by DNA-interacting transcription factors, such as XIST, which controls X-chromosome inactivation, or imprinted lncRNAs that direct allele-specific repression. A growing number of lncRNA transcription units, including CHASERR, PVT1 and HASTER (also known as HNF1A-AS1) act as transcription-stabilizing elements that fine-tune the activity of dosage-sensitive genes that encode transcription factors. Genetic experiments have shown that defects in such transcription stabilizers often cause severe phenotypes. Other lncRNAs, such as lincRNA-p21 (also known as Trp53cor1) and Maenli (Gm29348) contribute to local activation of gene transcription, whereas distinct lncRNAs influence gene transcription in trans. We discuss findings of lncRNAs that elicit a function through either activation of their transcription, transcript elongation and processing or the lncRNA molecule itself. We also discuss emerging evidence of lncRNA involvement in human diseases, and their potential as therapeutic targets.

Intraoperative Fluorescence Guidance for Breast Cancer Lumpectomy Surgery.

BACKGROUND: Although lumpectomy and mastectomy provide equivalent survival for patients with breast cancer, local recurrence after lumpectomy increases breast cancer mortality. Positive lumpectomy margins, which imply incomplete tumor removal, are the strongest predictor of local recurrence and are identified days after surgery, necessitating a second surgery. METHODS: In this prospective trial, we assessed margin status with or without pegulicianine fluorescence-guided surgery (pFGS) for stages 0 to 3 breast cancers. To prevent surgeons from performing smaller than standard lumpectomies in anticipation of pFGS assistance, patients were randomly assigned 10:1 to pFGS or control groups, thus randomization was not designed to provide a control group for evaluating device performance. In patients undergoing pFGS, additional pFGS-guided cavity margins were excised at sites of pegulicianine signal. We evaluated three coprimary end points: the percentage of patients for whom pFGS-guided margins contained cancer, sensitivity, and specificity. RESULTS: Overall, 406 patients received 1.0 mg/kg intravenous pegulicianine followed by lumpectomy. Among 392 patients randomly assigned, 316 had invasive cancers, and 76 had in situ cancers. In 27 of 357 patients undergoing pFGS, pFGS-guided margins removed tumor left behind after standard lumpectomy, 22 from cavity orientations deemed negative on standard margin evaluation. Second surgeries were avoided by pFGS in 9 of 62 patients with positive margins. On per-margin analysis, pFGS specificity was 85.2%, and sensitivity was 49.3%. Pegulicianine administration was stopped for adverse events in six patients. Two patients had grade 3 serious adverse events related to pegulicianine. CONCLUSIONS: The use of pFGS in breast cancer surgery met prespecified thresholds for removal of residual tumor and specificity but did not meet the prespecified threshold for sensitivity.

Enhancing the Adult and Paediatric Palliative Care System: Spanish Professionals' and Family Caregivers' Suggestions for Comprehensive Improvement.

This research critically explores deficiencies in the palliative care system, focusing on evaluation and treatment aspects for both adult and paediatric patients. Using a qualitative methodology, the study engages healthcare professionals and family caregivers to uncover perspectives on the existing state of palliative care. Conducted through three focus groups and a semi-structured in-depth interview with participants recruited from Virgen de la Arrixaca University Clinical Hospital, this research illustrates critical issues, highlighting the insufficient healthcare workforce and resources to meet the comprehensive needs of patients and their families. Recommendations include holistic care addressing social, emotional, psychological, socio-familiar, and economic dimensions, supported by embedded support groups and the enforcement of relationships with palliative associations. This study also advocates for improved health institutional coordination, social worker support, and ongoing health professional satisfaction monitoring. In paediatric care, specific demands involve specialised units, medical team continuity, 24 h paediatrician care, and a more professional paediatric approach. Beyond problem identification, this study offers valuable insights for shaping health policies and tools, incorporating new indicators and introducing grief bereavement support in clinical reports, contributing to the advancement of patient evaluation in palliative care.

Monitorización automática de estados de sedación en señales electroencefalográficas / Automatic monitoring of sedation states in electroencephalographic signals

La anestesia general proporciona al paciente estados de inconciencia, amnesia y analgesia, sin embargo, se reportan casos de despertar intraoperatorio. Debido a la incidencia de este fenómeno y sus efectos psicosomáticos, el Centro de Estudios de Neurociencias, Procesamiento de Imágenes y Señales en la Universidad de Oriente, y el Hospital General Juan Bruno Zayas Alfonso ambos en Santiago de Cuba, Cuba, implementan una metodología que permita detectar automáticamente estados de sedación anestésica aplicando Inteligencia Artificial. Para esto se emplearon las señales registradas por el canal electroencefalográfico F4, nueve parámetros espectrales, las Máquinas de Soporte Vectorial y los Sistemas Neuro-Difusos. En el reconocimiento automático de los estados de Sedación Profunda, Moderada y Ligera se logró una Exactitud de 96.12 por ciento, 90.06 por ciento y 90.24 por ciento respectivamente con las Máquinas de Soporte Vectorial, por lo que se propone el uso del canal electroencefalográfico F4 en la detección de estados anestésicos(AU)

General anesthesia provide the patient states of unconsciousness, amnesia and analgesia, however, cases of intraoperative awareness are reported. Due to the incidence of this phenomenon and the psychosomatic effects it causes, the Neuroscience Studies Center, Images and Signals Processing at the University of Oriente, and the General Hospital Juan Bruno Zayas Alfonso both in Santiago de Cuba, Cuba, implement a methodology that allows the automatic detection of anesthetic sedation states applying Artificial Intelligence. For this, the signals recorded by the electroencephalographic channel F4, nine spectral parameters, the Support Vector Machines and the Neuro-Fuzzy Systems were used. In the automatic recognition of the Sedation States: Profound, Moderate and Mild an Accuracy of 96.12 percent, 90.06 percent and 90.24 percent respectively was achieved with the Support Vector Machines, so the use of the electroencephalographic channel F4 is proposed in the detection of anesthetic states(AU)

Síndrome. Empleo inadecuado del término en la Discusión Diagnóstica. Semejanzas y divergencias en el criterio de expertos / Inappropriate use of the term Syndrome in the Diagnostic Discussion. Similarities and divergences in the criterion of experts

Introducción: hay casos de uso inadecuado del término síndrome en la discusión diagnóstica, en el Hospital Universitario V.I. Lenin de Holguín, lo que puede deberse a diversos factores. Objetivo: identificar, según el criterio de expertos, si existen en otras provincias de Cuba casos de uso inadecuado del término síndrome en la discusión diagnóstica, su repercusión negativa en el diagnóstico médico, principales manifestaciones del uso inadecuado, probables causas, necesidad de consenso y de reemplazo conceptual. Métodos: estudio observacional descriptivo con triangulación metodológica. Muestra intencionada de 15 expertos de diferentes provincias, profesores auxiliar o titular, máster, doctor en ciencias o ambos y especialistas de primer o segundo grado en medicina interna, quienes contestaron, por vía electrónica, una encuesta con diversos ítems y preguntas, tipo Escala Likert. La encuesta fue validada estadísticamente, los datos fueron procesados con uso de la mediana y de cuartiles mediante: test de Anova, coeficiente de correlación de Kendall y análisis clúster. Resultados: la mayoría de expertos concordaron en que existen casos de uso inadecuado del término síndrome en las discusiones diagnósticas, su negativa repercusión en el diagnóstico médico, posibles causas, necesidad de consenso con algunas divergencias, entre tres grupos de expertos, respecto a formas de manifestarse, otros factores influyentes y en especial sobre la ampliación del concepto síndrome, mediante la inclusión de signos propios de los exámenes complementarios, y su posible consecuencia en el algoritmo del método clínico. Conclusiones: aunque la mayoría de expertos concordaron sobre la existencia de uso inadecuado del término síndrome y otros aspectos relacionados, la existencia de divergencias, en especial sobre el reemplazo conceptual del término y su repercusión en el proceso diagnóstico hace plantear la existencia de una escuela heterodoxa (minoría), una escuela ortodoxa o tradicional (mayoría) y una escuela ecléctica, intermedia en número de expertos.

Introduction: there have been cases of misuse of the term syndrome in diagnostic discussion at the University Hospital of Holguin V.I. Lenin, which may be due to several factors. Objective: to identify, according to expert criteria, if there are cases of inappropriate use of the term syndrome in the diagnostic discussion in other provinces of Cuba, its negative repercussion in the medical diagnosis, main manifestations of the inadequate use, probable causes, need of consensus and of conceptual replacement. Method: descriptive observational study with methodological triangulation. Intentional sample of 15 experts from different provinces, assistant or master professors, master, doctor of science or both and specialists of first or second degree on internal medicine, who answered, electronically, a survey with various items and questions, Likert Scale. The survey was statistically validated; the data were processed using the median and quartiles using: anova test, Kendall correlation coefficient and cluster analysis. Results: the majority of experts agreed that there are cases of inadequate use of the term syndrome in diagnostic discussions, its negative repercussion in the medical diagnosis, possible causes, need for consensus with some divergences, among three groups of experts, regarding forms of manifestation, other influential factors and especially on the extension of the syndrome concept, through the inclusion of signs of complementary examinations and their possible consequence in the algorithm of the clinical method. Conclusions: although most experts agreed on the existence of inappropriate use of the term syndrome and other related aspects, the existence of divergences, especially on the conceptual replacement of the term and its repercussion in the diagnostic process, suggests the existence of a heterodox school (minority), an orthodox or traditional school (majority) and an eclectic school, intermediate in number of experts.

La bioética como quehacer filosófico / Bioethics as a philosophical task / A bioética como um quefazer filosófico

El artículo examina el estatuto epistemológico de la bioética como disciplina académica. El autor sostiene que el estatuto epistemológico de un discurso lo determina la pregunta fundamental que se plantea y la respuesta que se busca, focos integradores del discurso. En el caso de la bioética, la pregunta fundamental es de índole moral. La bioética es pues una disciplina ética que tiene su hogar epistemológico en la filosofía. El autor también defiende el concepto de "éticas aplicadas". Sugiere finalmente que el método de la bioética, sobre todo la que se hace desde nuestras latitudes, debería adoptar el círculo hermenéutico como metodología para su filosofar.

This article examines the epistemological statute of bioethics as an academic discipline. The author claims that the epistemological statute of a dialogue determines the fundamental question that is raised and the answer that is sought, essential points of discourse. In the case of bioethics, the fundamental question is of a moral nature. Therefore, bioethics is an ethical discipline that has its epistemological roots in philosophy. The author also defends the concept of applied ethics. Finally, he suggests that bioethical methods, above all especially what is realized in our latitudes, should adopt the Hermeneutic Circle as the methodology for its philosophizing.

Percepción popular y profesional del significado del vocablo empacho / Popular and professional perception of the meaning of the word

Con el objetivo de establecer los criterios populares y profesionales sobre el significado del vocablo empacho, sus semejanzas y divergencias, se realizaron dos investigaciones exploratorias paralelas en el período comprendido entre agosto de 2005 y diciembre de 2006. En la dimensión popular se definió como universo la totalidad de habitantes del municipio de Holguín y se obtuvo una muestra intencional de 158 personas mayores de 18 años de edad y dispuestas a cooperar. El universo profesional, por su parte, comprendió el total de pediatras, así como de cirujanos y gastroenterólogos que atienden pacientes adultos en los tres hospitales provinciales del territorio. Ambas muestras, intencionadas, incluyeron 17 pediatras y 10 gastroenterólogos, respectivamente, quienes laboran con adultos, todos con 10 años o más de experiencia profesional y en la atención a pacientes que refirieron padecer un empacho. La definición más frecuente en el criterio popular fue ®parálisis de la digestión¼, seguida por la de ®indigestión¼. La mayoría de los pedíatras identificaron el empacho con la indigestión. Los gastroenterólogos también seleccionaron la indigestión y, junto a ella, "un trastorno con marcada disminución de la motilidad gástrica". En este último caso se aprecia una mayor semejanza con los criterios populares que asocian el término empacho con una parálisis de la digestión.

In oder to establish the popular and professional criteria of the meaning of the word empacho, their similarities and divergences, two exploratory and parallel investigations were carried out from August, 2005, to December 2006. In the popular dimension, all the inhabitants of Holguín municipality were considered as the universe, and an intentional sample of 158 people over 18, ready to cooperate, was selected. On the other hand, the professional universe was composed of all the pediatricians, surgeons and gastroenterologists who give attention to adult patients in the three provincial hospitals of the territory. Both intended samples included 17 pediatricians and 10 gastroenterologists, respectively. All of them had more than 10 years of professional experience, and had seen patients suffering from empacho. The most frequent definition in the popular criterion was "paralysis of the digestion", followed by "indigestion". Most the pediatricians identified the empacho with the word indigestion. The gastroenterologists also selected indigestion and, together with it, "a disorder with marked reduction of the gastric motility". In this case, it is observed a greater similarity with the popular criteria that associates the term empacho with a paralysis of digestion.

Tratamiento quirúrgico del cáncer colorrectal. Experiencia de 10 años en el INCMNSZ / Colorectal cancer surgical treatment. The 10-year experience at the INCMNSZ

Objetivo: conocer los resultados a corto y largo plazos del tratamiento quirúrgico en el carcinoma del colon y recto en el INCMNSZ. Antecedentes: el cáncer colorrectal es la segunda neoplasia maligna más frecuente del tubo digestivo en México. Su incidencia continúa en aumento, siendo primordial su identificación en estadios tempranos, en los que la cirugía puede ser curativa. Método: estudio retrolectivo, descriptivo y observacional. Se estudiaron 165 pacientes intervenidos quirúrgicamente por cáncer colorrectal entre 1985 y 1994 en el INNSZ, comparando variables de los pacientes y de la intervención quirúrgica en sí, con base en su relación con la morbilidad y mortalidad operatorias, así como supervivencia a cinco años. Resultados: la supervivencia fue mayor en cirugía con intento curativo en tumores de colon con respecto a los rectales (p < 0.05). Hubo mayor supervivencia a cinco años mientras más temprano fuera el estadio al momento del diagnóstico. La morbilidad operatoria fue de 30 por ciento, principalmente infecciones de la herida. La mortalidad operatoria fue de 3.6 por ciento, siendo sepsis la causa principal. Se encontró mayor mortalidad quirúrgica en mayores de 65 años. Hubo mayor morbilidad en la cirugía rectal con respecto a la cirugía del colon. Conclusiones: es necesario detectar a los pacientes con cáncer colorrectal en estadios más tempranos que permitan un manejo quirúrgico con fines curativos, pues el estadio al momento del diagnóstico se relaciona directamente con la supervivencia del paciente. La edad fue un factor de riesgo para mortalidad quirúrgica, y la cirugía de recto lo fue para morbilidad.

Epidemiología de la Ciguatera en 16 años de estudio en la provincia de Ciego de Ávila / Epidemiology of ciaguatera poisoning during 16 years of study in the province of Ciego de Avila

Se analizaron los brotes de ciguatera en el período de 1983 a 1998, en la etapa se reportaron 46 brotes con 305 casos sin ningún fallecido. Se reportó mayor frecuencia de brotes entre 1990 y 1995. Del total de brotes, 43 se reportaron en población autóctona y 3 en extranjeros, predominaron los brotes residenciales (82,6 porciento). Se halló, como fuente principal de suministro del pescado, la compra a particulares y el autoconsumo de pescadores aficionados, solo en un brote el pescado fue suministrado por la empresa pesquera, lo cual demuestra la efectividad de las regulaciones al respecto. Se detectaron 14 especies de pescado que provocaron brotes, predominó la picúa (30,4 porciento) el jurel (17 porciento) el aguají y la cubera (10,8 porciento). Se detectó mayor número de brotes en el trimestre de julio-septiembre con 22 (47,8 porciento) y los meses de mayor número de casos fueron agosto y septiembre. Se destacaron los grupos de edades de 15 a 30 años (40,6 porciento) y el de 31 a 46 años (31,4 porciento) predominó el sexo masculino con el 60,3 porciento. El período de incubación osciló entre 1 y 25 h la mayor frecuencia estuvo en el rango de 4 a 6 h (34,4 porciento)

Proctocolectomía total con anastamosis ileo-anal de reservorio en "J"- Experiencia en el Instituto Nacional de la Nutrición Salvador Zubirán / Total proctocolectomy with ileal pouch anal anastomosis. Experience at the Instituto Nacional de la Nutricion Zubiran in Mexico

Antecedentes. La proctocolectomía total y anastomosis ileo-anal (PCTAIA) es el procedimiento de elección para los pacientes con colitis ulcerativa crónica inespecífica y poliposis adenomatosa familiar que requieren cirugía. La frecuencia de presentación de estas enfermedades es baja en México, por lo que la experiencia con este procedimiento es escasa. Objetivo. Analizar la morbi-mortalidad operatoria y resultados funcionales a largo plazo en una serie de pacientes sometidos a esta operación en un hospital de referencia en México. Material y métodos. Se analizan retrospectivamente 44 pacientes consecutivos operados de PCTAIA entre 1987 y 1997. La operación incluyó resección mucosa de la zona de transición, anastomosis manual del reservorio ileal en "J" e ileostomía temporal en todos los pacientes. Se determinaron las causas y cifras de morbilidad y mortalidad posoperatorias, así como los resultados funcionales y complicaciones a largo plazo. Resultados. La edad promedio fue de 33 ñ 15 años. Hubo 23 mujeres (52 por ciento) y 21 hombres (48 por ciento). Los principales diagnósticos fueron colitis ulcerativa crónica inespecífica en 59 por ciento y poliposis adenomatosa familiar en 36 por ciento. La morbilidad global fue del 39 por ciento y la mortalidad del 2 por ciento. Con un seguimiento promedio de 24 meses, el promedio de evacuaciones diurnas que presentaron los pacientes fue de 4, 10 por ciento presentaron escurrimiento diurno, 30 por ciento escurrimiento nocturno, y ninguno presentó incontinencia. Tres pacientes han presentado inflamación del reservorio, con respuesta adecuada a antibióticos. Dos pacientes han presentado fístulas del reservorio ileal a largo plazo, pero ninguno requirió de su resección. Conclusiones. PCTAIA es una operación factible en nuestro medio que se acompaña de cifras aceptable de morbi-mortalidad y resultados funcionales satisfactorios

Calidad de presentación de los trabajos libres de investigación en el Congreso Nacional de Gastroenterología: Morelia 1997 / Quality of the presentation of free research papers in the National Congress of Gastroenterology: Morelia 1997

Antecedentes. La calidad de presentación de un trabajo de investigación no es necesariamente paralela a su calidad metodológica. Objetivo: Analizar la calidad de presentación de los trabajos libres orales, presentados en el Congreso Nacional de Gastroenterología (Morelia 1997). Metodología: Se realizó un estudio prospectivo que evaluaron los siguientes aspectos: limitación al tiempo asignado, utilización y diseño de diapositivas adecuados, así como mención de las principales características metodológicas. Resultados. En la mayoría de los trabajos, la calidad de presentación fue alta. Los problemas susceptibles de mejoría que se encuentran con mayor frecuencia fueron: la falta de limitación al tiempo asignado (24 por ciento), la saturación en el contenido (32 por ciento) y el número de diapositivas (23 por ciento). Conclusiones. El conocimiento de los resultados obtenidos puede ayudar a mejorar las presentaciones orales de los trabajos libres en los congresos nacionales de gastroenterología
