Cánula Nasal de Alto Flujo Asimétrica: una Revisión Narrativa / Asymmetrical High Flow Nasal Cannula: a Narrative Review

Los sistemas de Cánula nasal de alto flujo (CNAF) han sido ampliamente utilizados en el campo clínico como soporte no invasivo en el manejo de la falla respiratoria aguda (sobre todo hipoxémica) y cuidados post extubación. Clínica y fisiológicamente, las cánulas nasales de alto flujo son capaces de entregar un flujo de oxigeno alto que, debido a que ese gas se encuentra optimamente humidificado y calefaccionado, permite una mejor tolerancia por parte del paciente al ser comparada con las cánulas de oxigeno tradicionales. Por otra parte, este alto. Flujo es capaz de generar una presión positiva al final de la espiración (CPAP) en la vía área y favorecer tanto en barrido de dióxido de carbono (CO2) desde la vía aérea superior, lo que disminuye el trabajo respiratorio del paciente y mejora su confort.. Sin embargo; aún existe un alto porcentaje de pacientes que fracasan la terapia con CNAF y requiere soportes mas complejos como la ventilación mecánica, ya sea imvasiva o no. Estos resultados con la terapia CNAF pueden ser influidos por aspectos técnicos como, por ejemplo, la turbulencia que pueden generar estos sistemas a nivel de la región nasal. Por esta razón se han desarrollado nuevas tecnologías en el diseño y uso de interfaces para suministrar este alto flujo. Una de estas innovaciones es el uso de cánulas asimétricas, las que potencian los beneficios fisiológicos que entrega una cánula de alto flujo convencional. La presente revisión pretende exponer las principales diferencias que presenta el sistema de alto flujo convencional versus la nueva interface asimétrica.

High-flow nasal cannula (HFNC) systems have been widely used in the clinical field as non-invasive support in the management of acute respiratory failure (especially hypoxemic) and post-extubation care. Clinically and physiologically, high flow nasal cannulas are capable of delivering a high flow of oxygen which, because this gas is optimally humidified and heated, allows better tolerance by the patient when compared to traditional oxygen cannulas. . On the other hand, this high. Flow is capable of generating positive pressure at the end of expiration (CPAP) in the airway and favoring the sweep of carbon dioxide (CO2) from the upper airway, which reduces the patient's respiratory work and improves their comfort. .. However; There is still a high percentage of patients who fail therapy with HFNC and require more complex supports such as mechanical ventilation, whether invasive or not. These results with HFNC therapy can be influenced by technical aspects such as, for example, the turbulence that these systems can generate in the nasal region. For this reason, new technologies have been developed in the design and use of interfaces to provide this high flow. One of these innovations is the use of asymmetric cannulas, which enhance the physiological benefits provided by a conventional high-flow cannula. The present review aims to expose the main differences that the conventional high flow system presents versus the new asymmetric interface.

Foliar application of triacontanol ameliorates heat stress through regulation of the antioxidant defense system and improves yield of eggplant

Abstract Transplanting time and genotype contribute to improving crop yield and quality of eggplant (Solanum melongena L.). A field experiment was conducted to investigate the impact of foliar applied of triacontanol (TRIA) and eggplant genotypes 25919, Nirala, 28389 and Pak-10927,transplanted on 1 March,15 March, and 1 April on exposure to high air temperature conditions. The experiment was performed according to Randomized Complete Block Design and the data was analyzed by using Tuckey,s test . The TRIA was applied at 10µM at flowering stage; distilled water was used as the control. Rate of photosynthesis and transpiration, stomatal conductance, water use efficiency, and effects on antioxidative enzymes (superoxide dismutase, catalase and peroxidase) were evaluated. The 10µM TRIA increased photosynthesis rate and water use efficiency and yield was improved in all genotypes transplanted at the different dates. Foliar application of 10µM TRIA increased antioxidative enzyme activities (SOD, POD & CAT) and improved physiological as well as biochemical attributes of eggplant genotypes exposed to high heat conditions. Highest activity of dismutase enzyme 5.41mg/1g FW was recorded in Nirala genotype in second transplantation. Whereas, lowest was noted in PAK-10927 (2.30mg/g FW). Maximum fruit yield was found in accession 25919 (1.725kg per plant) at 1st transplantation with Triacontanol, whereas accession PAK-10927 gave the lowest yield (0.285 kg per plant) at control treatment on 3rd transplantation. Genotype, transplanting date and application of TRIA improved growth, yield and quality attributes under of heat stress in eggplant.

Sexual function according to infiltration of endometriosis of the rectovaginal septum: a cross-sectional study

SUMMARY OBJECTIVE: The aim of this study was to associate the degree of infiltration of rectovaginal septum endometriosis with dyspareunia and sexual function. METHODS: A cross-sectional study was carried out with 127 women followed up at a tertiary hospital from March 2021 to March 2022. The women's sociodemographic and clinical conditions and dyspareunia were evaluated. The sexual function was evaluated by the Female Sexual Function Index. RESULTS: A total of 53 women with type I, 37 with type II, and 37 with type III rectovaginal septum endometriosis were evaluated. The women had a mean age of 38.76±6.63 years and a mean body mass index of 27.62±5.11 kg/m2. The mean time of diagnosis of endometriosis was 6.94±4.98 years. On average, the study participants engaged in sexual activity/intercourse 1.88±1.25 times per week. There was no difference between the dyspareunia score (p=0.822) and sexual function (p=0.174) according to the types of rectovaginal septum endometriosis. Overall, 93.7% of the women with endometriosis had sexual dysfunction. There was no correlation between the degree of rectovaginal septum endometriosis infiltration with dyspareunia (r=0.05; p=0.55) or sexual function (r=0.07; p=0.39). CONCLUSION: Women with endometriosis have impaired sexual function, regardless of the degree of endometriosis infiltration.

Efecto del estrés agudo y de la variación del estímulo masticatorio sobre el dolor nociceptivo somático en un modelo murino

Introducción. El estrés agudo se relaciona con la enérgica liberación de catecolaminas, citoquinas y cortisol, las cuales afectan la percepción dolorosa. La masticación estimula neuronas serotoninérgicas, dichas neuronas modulan a las vías neurales del dolor; sin embargo, la relación entre dichas variables aún está en proceso de entendimiento. Objetivo. Determinar el efecto del estrés agudo y del estímulo masticatorio sobre el dolor. Métodos. Experimento que se desarrolló en el bioterio de la Facultad de Medicina de la UNMSM. 40 ratones Balb/c machos de 8 semanas de edad. Los ratones fueron asignados aleatoriamente en 5 grupos iguales. A: semana 1 sin ningún estímulo y semana 2 estimulo masticatorio + estrés. B: semana 1 sin ningún estímulo y semana 2 estrés. C: semana 1 estrés y semana 2 sin ningún estímulo. D: semana 1 estímulo masticatorio + estrés y semana 2 sin ningún estímulo. E: control, sin ningún estimulo. El dolor se evaluó en los 5 grupos a los 7 y 14 días mediante la prueba de tiempo de retirada de la cola ante estímulo térmico. Resultados. Se empleó la prueba de ANOVA para la evaluación intergrupo, no hallándose diferencia significativa. Mediante la prueba de t student para muestras relacionadas se hizo la evaluación intragrupo donde se encontró diferencia significativa entre los 7 vs los 14 días tanto en el grupo A (p=0,029) como en el grupo C (p=0,03). Conclusión. El efecto del estrés agudo sobre la percepción dolorosa fue disminuida por el estímulo masticatorio en ratones Balb/c.

Introduction. Acute stress is related to the energetic release of catecholamines, cytokines, and cortisol, which trigger pain perception. Chewing stimulates serotonergic neurons, these neurons modulate the neural pathways of pain; however, the relationship between these variables is still in the process of understanding. Objective. To determine the effect of acute stress and chewing stimulus on pain. Methods. an experiment that was developed in the Faculty of Medicine of the UNMSM. 40 eight-week-old male Balb/c mice were randomly assigned into 5 equal groups. A: week 1 without any stimulus and week 2 chewing stimulus + stress. B: week 1 without any stimulus and week 2 stress. C: week 1 stress and week 2 without any stimulus. D: week 1 masticatory stimulus + stress and week 2 without any stimulus. E: control, without any stimulus. Pain was assessed in the 5 groups at 7 and 14 days using the tail-withdrawal time test before thermal stimulation. Results. The ANOVA test was used for the intergroup evaluation, finding no significant difference. Using the t student test for related samples, the intragroup evaluation was made, where a significant difference was found between 7 vs. 14 days, both in group A (p=0.029) and in group C (p=0.03). Conclusion. The effect of acute stress on pain perception was decreased by chewing stimulus in Balb/c mice.

Sampling reflex as a new manometric marker in the diagnosis of defecation disorders: systematic review

Introduction: Distension of the rectum wall and subsequent momentary relaxation of the internal anal sphincter (IAS) trigger a reflex called the rectoanal inhibitory reflex (RAIR). This same rectal distension causes a reflex contraction of the external anal sphincter (EAS), responsible for conscious continence called rectoanal excitatory reflex (RAER). This set of reflexes are named sampling reflex. Objectives: The sampling reflex is necessary to initiate defecation or flatulence. The objective of this study is to evaluate the sampling reflex and its practical applicability as a manometric marker of the main defecation disorders. Methodology: This review followed the Preferred Reporting Items for Systematic reviews and Meta-Analysis (PRISMA) items. The development method consisted of searching for articles in the research platforms BVS, PubMed, Cochrane Library, SciELO and ScienceDirect and for the selection of articles the Rayyan Platform was used. The articles resulting from the search strategies were added to the platform and five collaborators were invited for the blind selection. Finally, 6 articles were included in the final review. Results: An intact sampling reflex allows the individual to facilitate discrimination between flatus and stool and to choose whether to discharge or retain rectal contents. On the other hand, an impaired sampling reflex can predispose an individual to incontinence. Therefore, it was observed that patients with defecation disorders had an impaired sampling reflex, since it was found that constipated patients have incomplete opening of the IAS, lower amplitude of RAIR and increase of RAER. Most incontinent patients present a failure in the recruitment of the EAS, a decrease in the RAER and an increase in the RAIR, in duration and amplitude. (AU)

Control Efficacy of Jingdusha against Corynespora cassiicola (Hyphomycetales: Dematiaceae) on Cucumber

Aims: The paper aimed to clarify the effect of cucumber target leaf spot (TLS) under the Jingdusha (JDS) treatment. Study Design: We applied the method of artificial inoculation in the pot, and analyzed the changes in growth indexes and physiological characteristics. Place and Duration of Study: In 2018, these experiments were conducted in College of Bioscience and Biotechnology of Shenyang Agricultural University (Lab 240). Methodology: The seedlings in the two-leaf period were induced by the best application scheme of JDS, then inoculated Corynespora cassiicola for 24 h. Cucumber seedlings of each treatment group were randomly selected for photographing and growth index determination after inoculation for 5 d. The leaves of cucumber seedlings in each treatment group were randomly collected at 1 d, 3 d, 5 d, 7 d, and 9 d after inoculation for the determination of physiological and biochemical indicators. Results: When C. cassiicola infects cucumber, JDS can effectively improve the growth and photosynthetic pigment content of cucumber, reduce the degradation of chlorophyll (Chl) under the stress of C. cassiicola, strengthen the variety of metabolic responses in the plant, repair the enzyme protection system of cucumber leaves, reduce the accumulation of reactive oxygen species, shorten the process of membrane lipid peroxidation in blades. Conclusion: Taken together, these results suggest that JDS can improve the resistance of cucumber seedlings to C. cassiicola by regulating growth indexes and physiological characteristics. This work will provide a theoretical basis for further elucidating the molecular mechanism of JDS in cucumber defense against C. cassiicola.

Design of Exercise Device for Older Adults / Diseño de Dispositivo para Ejercitación de Adultos Mayores

ABSTRACT Older adults should perform physical activity to improve cardiorespiratory functions. Aerobic exercises improve cardiovascular function, decrease basal heart rate and blood pressure, and improve mood and energy. To facilitate the execution of aerobic physical activity in older adults, the objective of this research was to design an exercise device for older adults. Starting from design specifications such as comfort, size, weight, resistance, and cost, we developed the detailed design of a horizontal bicycle. The designed device, thanks to its horizontally disposed structure, its adequate resistance to pedaling, its dimensioning based on anthropometric measurements of the Chilean population, and the disposition of sensors for heart rate and oxygen saturation, is suitable for older adults. Its weight and size also make it convenient for use inside the home, and the use of materials, components, and manufacturing processes available nationally and within the cheapest options, increases the possibility of access by older adults.

Con la finalidad de facilitar la ejecución de actividad física del tipo aeróbica en adultos mayores, se planteó el objetivo de este trabajo, centrado en diseñar un dispositivo para su ejercitación. Partiendo de especificaciones de diseño como comodidad, tamaño, peso, resistencia y costo, se desarrolló el diseño de detalle de una bicicleta horizontal. El dispositivo diseñado, gracias a la disposición horizontal de la estructura, la resistencia adecuada al pedaleo, su dimensionamiento con base a medidas antropométricas de población chilena, y la disposición de sensores para heart rate and oxygen saturation, es adecuado para adultos mayores. Además, su peso y tamaño lo hacen conveniente para el uso dentro de las viviendas, del mismo modo, el uso de los materiales, componentes y proceso de manufactura disponibles nacionalmente y dentro de las opciones más económicas, aumentan la posibilidad de acceso por parte de los adultos mayores.

Importancia de la medición de la Viscosidad sanguínea: retos y limitaciones

La sangre es una mezcla de componentes que tiene su propia identidad. Una de las propiedades físicas que adquiere es su viscosidad, la cual es la resistencia que ofrece para desplazarse. A diferencia de sus componentes (como glucosa, hemoglobina, colesterol, etc.), la sangre no posee un nivel único de viscosidad, sino que esta es variable debido a diversos factores. Exponemos algunos principios físicos que nos permitirán entender mejor esta dinámica de la viscosidad sanguínea, y su posible aplicación en algunos fenómenos hemodinámicos, así como la complejidad de su medición en la práctica clínica habitual.

Blood is a mixture of components that has its own identity. One of the physical properties that it acquires is its viscosity, which is the resistance it offers to move. Unlike its components (such as glucose, hemoglobin, cholesterol, etc.), blood does not have a single level of viscosity, but it is variable due to various factors. We present some physical principles that will allow us to better understand these dynamics of blood viscosity, and its possible application in some hemodynamic phenomena, as well as the complexity of its measurement in routine clinical practice.

Resultados: Disfunção familiar e pouco apoio dos amigos foram encontrados em quase metade dos participantes, níveis de preocupação moderada próximos a 70 %, alta frequência de demandas do ambiente (estressores), reações comportamentais e presença de sintomas diante de estímulos estressantes. Houve associação entre alta frequência de inquietação em situações cotidianas e pertencimento aos semestres básicos, baixa frequência do uso de estratégias de enfrentamento e sexo feminino, alta frequência de reações comportamentais e disfunção familiar. Conclusões: Os principais fatores identificados foram pertencer aos semestres básicos, ser mulher e a presença de disfunção familiar. Os níveis de estresse e disfuncionalidade familiar sugerem um alerta para intervir da unidade de bem-estar da universidade para prevenir condições desfavoráveis na saúde e desempenho acadêmico dos estudantes.

Sexual dysfunction in Brazilian patients with multiple sclerosis / Disfunção sexual em pacientes brasileiros com esclerose múltipla

Abstract Background People with multiple sclerosis (PwMS) show an increased risk of sexual dysfunction (SD), both in women and men. Objective The aim of the present study was to apply the Multiple Sclerosis Intimacy and Sexuality Questionnaire-19 (MSISQ-19) and evaluate our results by comparing them with those in in the literature, as well as to assess the ease of applying the scale and the engagement of the patients in discussing the topic of sexuality. Methods We developed and applied a web-based Google form questionnaire that the respondents completed online, which included the MSISQ-19, for the assessment of sexual function. Baseline characteristics were reported as proportions and mean ± standard deviation (SD) or median ± interquartile range (IQR) as appropriate according to data distribution. Categorical variables were stratified by sex and compared with chisquared tests. Statistical analyses were performed using STATA v. 16 (StataCorp., College Station, TX, USA). Results Of the 621 respondents, 541 were included in the analysis. Among the patients with MS, a total of 347 (64.14%) exhibited SD. When stratified by gender, the frequencies of SD were not significantly different. Conclusion There is a high incidence of sexual dysfunction among PwMS and we need to identify the reasons for this and implement strategies to treat and counsel our patients. The MSISQ-19 can be used to help clinicians to assess sexual functioning in a quick and easy way and give patients the possibility to address this topic and receive appropriate help and support.

Análisis de indicadores relacionados con el estrés académico en estudiantes universitarios

Introducción: a pesar del empleo de indicadores fisiológicos, psicofisiológicos y psicológicos asociados al estrés académico, la comunidad científica no ha logrado definir con total claridad qué comportamiento debe seguir. Objetivo: analizar el comportamiento de indicadores relacionados con el estrés académico en estudiantes universitarios. Materiales y métodos: están referidos a la aplicación de un procedimiento que consta de tres etapas: preparatoria, experimental y resultados. Se evaluaron los indicadores variabilidad de la frecuencia cardiaca, umbral de discriminación táctil, percepción de profundidad, tiempo de reacción simple y Prueba de Yoshitake. Como herramienta para el procesamiento de la información se utilizó el software Statgraphic Centurion 15.0. Resultados: existen diferencias significativas entre el antes y el después para la muestra examinada, además de diferencias entre las variaciones obtenidas de los indicadores entre los grupos. Se detectaron discrepancias entre los resultados obtenidos en el indicador tiempo de reacción simple, en presencia de estrés académico, y los obtenidos por otros investigadores. Conclusiones: fue demostrada la presencia de diferencias significativas en el comportamiento de los indicadores seleccionados ante la presencia de estrés académico en estudiantes universitarios, al menos bajo condiciones experimentales.

Introduction: in spite of the use of physiological, psycho-physiological and psychological indicators associated to academic stress, the scientific community has not been able to totally clear define what behavior should be followed. Objective: to analyze the behavior of indicators related to academic stress in university students. Materials and methods: they refer to the application of a procedure consisting in three stages: preparatory, experimental and results. The indicators heart frequency variability, tactile discrimination threshold, depth perception, simple reaction time and Yoshitake test were evaluated. The Statgraphic Centurion 15.0 software was used as a tool for information processing. Results: there are significant differences between before and after for the examined sample, in addition to differences between the variations obtained from indicators between the groups. Discrepancies were detected between the results obtained in the indicator simple reaction time, in the presence of academic stress, and those obtained by other researchers. Conclusions: the existence of significant differences in the behavior of chosen indicators in the presence of academic stress in university students was demonstrated, at least under experimental conditions.

Efecto del estímulo masticatorio y estrés agudo sobre la interleuquina 6, la memoria y el aprendizaje espacial en ratones Balb/c

Introducción. El estrés agudo altera la memoria y aprendizaje espacial y la expresión de la interleuquina 6 (IL-6), mientras que el estímulo masticatorio evitaría dichos efectos. Objetivo. Determinar el efecto del estímulo masticatorio y el estrés agudo sobre la expresión de interleuquina 6, la memoria y el aprendizaje espacial en ratones. Métodos. Experimento con 70 ratones albinos machos de 2 meses de edad de la cepa Balb/c que fueron distribuidos aleatoriamente en grupo A1: estrés agudo 1 hora; grupo A2: estrés agudo 1 hora + estímulo masticatorio 1 hora; grupo B1: estrés agudo 2 horas; grupo B2: estrés agudo 2 horas + estímulo masticatorio 2 horas; grupo C1: estrés agudo 3 horas; grupo C2: estrés agudo 3 horas + estímulo masticatorio 3 horas; y grupo D: sin intervención. Durante 3 días, se evaluó la memoria y el aprendizaje espacial en el laberinto acuático de Morris. La IL-6 fue determinada mediante ELISA. Resultados. La IL-6 fue mayor en el grupo B2 vs los demás grupos (p < 0,001). Además, en el primer día de evaluación, la adquisición de memoria y aprendizaje espacial fue menor en el grupo A1 vs A2 (p = 0,042). Conclusión. Solo en el primer día de evaluación encontramos que el estímulo masticatorio previno la disminución de la adquisición de memoria y aprendizaje espacial en ratones sometidos a estrés agudo de baja intensidad. Los resultados en general no fueron concluyentes sobre el efecto del estímulo masticatorio. Además, la IL-6 fue mayor en el estrés + el estímulo masticatorio (grupo B2) sobre el resto.

Introduction. Acute stress alters memory and spatial learning and the expression of interleukin 6, the chewing stimulus would prevent these effects. Objective. To determine the effect of chewing stimulation and acute stress on the expression of interleukin 6 and memory and spatial learning in mice. Methods. Experiment where 70 male albino mice of the Balb/c of age 2 month were randomly distributed into: Group A1: acute stress 1 hour; Group A2: acute stress 1 hour + chewing stimulus 1 hour; Group B1: acute stress 2 hours; Group B2: acute stress 2 hours + chewing stimulus 2 hours; Group C1: acute stress 3 hours; C2: acute stress 3 hours + chewing stimulus 3 hours; Group D: without intervention. For 3 days, spatial memory and learning were tested in the Morris water maze. Interleukin 6 (IL-6) was analyzed by ELISA test. Results. IL-6 was higher in the B2 group vs the other groups (p<0.0001). In addition, on the first day of evaluation, the acquisition of spatial memory and spatial was lower in the A1 vs. A2 group (p=0.042). Conclusión. Only on the first day of evaluation, we found that the masticatory stimulus prevented the decrease in memory acquisition and spatial learning in mice subjected to low-intensity acute stress. The results were generally inconclusive on the effect of masticatory stimulation. In addition, IL-6 was higher in the stress + masticatory stimulus (group B2) over the rest.

Fragilidad en adultos mayores y actividad física

La detección precoz de la fragilidad y el empleo oportuno de técnicas diagnósticas, terapéuticas y rehabilitadoras pueden modificar positivamente la expresión esperada de la discapacidad en el anciano. Las intervenciones tempranas, que incluyan ejercicio y movilización, ayudan a disminuir la gravedad de complicaciones asociadas y facilitan la recuperación funcional de este grupo etáreo. Los ejercicios de resistencia, flexibilidad, equilibrio y fuerza reducen la incidencia y el riesgo de caídas, la morbilidad y la mortalidad y previenen el deterioro funcional.

Early detection of frailty and the timely use of diagnostic, therapeutic and rehabilitative techniques can positively modify the expected expression of disability in the elderly. Early interventions, which include exercise and mobilization, help reduce the severity of associated complications and facilitate the functional recovery of this age group. Resistance, flexibility, balance and strength exercises reduce the incidence and risk of falls, morbidity and mortality and prevent functional deterioration.

EFFECT OF EARLY AMBULATION ON MATERNAL OUTCOME AMONG POST CAESAREAN MOTHERS

The purpose of the study was to determine the effect of early ambulation on maternal outcome among post caesarean mothers. The objectives of the study was to assess the effect of early ambulation on maternal outcome among post caesarean mothers and to ?nd out the association between the maternal outcome among post caesarean mothers with selected demographic variables. This study was based on Roy's adaptation theory. The research design adopted for the study was post-test only control group design. 60 post caesarean mothers who ful?lled the inclusion criteria were selected for the study, out of which 30 post caesarean mothers were in experimental group and 30 post caesarean mothers were in control group. Non-probability purposive sampling technique was used to select the samples. The tool used to assess the effect of early ambulation was post caesarean bio physiological health parameters chart. The study was conducted in General Hospital, Neyyattinkara. The effectiveness of early ambulation was assessed by comparing the maternal outcome of post caesarean mothers in experimental group and control group. The result shows that there was a signi?cant difference in the maternal outcome among post caesarean mothers in the experimental group after performing early ambulation and there was an association between the maternal outcome among post caesarean mothers with selected demographic variables except in case of period of gestation.

Comparison of sexual functions in women with and without type 1 diabetes

SUMMARY OBJECTIVE: This study aimed to investigate female sexual function in patients with type 1 diabetes by comparing female sexual function index scores between women with and without type 1 diabetes. METHODS: A total of 62 women with type 1 diabetes and 69 age-matched women without diabetes but with similar backgrounds were enrolled in the patient and control groups, respectively. All participants were sexually active and had no systemic diseases other than diabetes in the patient group. RESULTS: The frequency of female sexual dysfunction was significantly higher, and the mean female sexual function index score was significantly lower in women with diabetes compared to the control group (p=0.01). There was a significant relationship between sexual dysfunction and duration of diabetes, glycosylated hemoglobin test, and body mass index (p<0.05). CONCLUSION: This study demonstrates that female sexual dysfunction is more common among women with type 1 diabetes than among women without type 1 diabetes. Patients with type 1 diabetes should be evaluated in terms of sexual health. Health professionals should give more attention to and provide guidance regarding sexual function in women with type 1 diabetes.

Bases científicas del principio de curación homeopática en la farmacología moderna / Scientific bases of the homeopathic healing principle in modern pharmacology

La homeopatía emplea el denominado 'principio de similares' como método terapéutico ­ el cual consiste en administrar medicamentos que provocan ciertos síntomas en individuos sanos para tratar síntomas similares en individuos enfermos (similia similibus curantur) - para inducir una reacción curativa secundaria del cuerpo en contra de sus propios trastornos. Esta reacción secundaria (vital, homeostática o paradójica) del cuerpo se basa en el 'efecto de rebote' de los fármacos modernos, un tipo de evento adverso que se produce después de interrumpir varias clases de fármacos prescritos según el 'principio de los contrarios' (contraria contrariis curantur). Objetivo: La presente revisión ha buscado justificar científicamente el principio de curación homeopática frente a la farmacología clínica y experimental a través de un estudio sistemático del efecto de rebote de los fármacos modernos o reacción paradójica del cuerpo. Métodos: Empleando como referencia estudios y revisiones sobre el tema publicados a partir de 1998, actualizamos los datos añadiendo estudios recientes incluidos en la base de datos PubMed. Resultados: El efecto de rebote se produce después de interrumpir varias clases de fármacos con acción contraria a los síntomas de las enfermedades, exacerbándolos a niveles superiores a aquellos previos al tratamiento. Independientemente de la enfermedad, fármaco, dosis y duración del tratamiento, el fenómeno del rebote se manifiesta en una pequeña proporción de los individuos susceptibles. Siguiendo las premisas homeopáticas, los fármacos modernos también podrían usarse según el principio de la similitud terapéutica, empleando entonces el efecto de rebote (reacción paradójica) con propósito curativo. Conclusiones: Evidenciado por cientos de estudios que constatan la similitud de conceptos y manifestaciones, el efecto de rebote de los fármacos modernos justifica científicamente el principio de la cura homeopática. Aunque el fenómeno de rebote es un evento adverso estudiado por la farmacología moderna, no es conocido por los profesionales de la atención médica, lo cual priva a los médicos de un conocimiento indispensable para el manejo seguro de los fármacos.

Homeopathy employs the so-called 'principle of similars' as therapeutic method - which consists in administering medicines that cause certain symptoms in healthy individuals to treat similar symptoms in sick individuals (similia similibus curantur) - to induce a secondary and healing reaction by the body against its own disorders. This secondary (vital, homeostatic or paradoxical) reaction of the body is based on the 'rebound effect' of modern drugs, a type of adverse event that occurs following discontinuation of several classes of drugs prescribed according to the 'principle of contraries' (contraria contrariis curantur). Aim: The present review sought to scientifically substantiate the homeopathic healing principle vis-à-vis experimental and clinical pharmacology through a systematic study of the rebound effect of modern drugs or paradoxical reaction of the body. Methods: Employing as reference studies and revisions on the subject published since 1998, we updated the data adding recent studies included in database PubMed. Results: The rebound effect occurs after discontinuation of several classes of drugs with action contrary to the symptoms of diseases, exacerbating them to levels above the ones before treatment. Regardless of disease, drug, dose and duration of treatment, the rebound phenomenon manifests in a small proportion of susceptible individuals. Following the homeopathic premises, modern drugs might also be used according to the principle of therapeutic similitude, thus employing the rebound effect (paradoxical reaction) with curative intent. Conclusions: Evidenced by hundreds of studies that attest to the similarity of concepts and manifestations, the rebound effect of modern drugs scientifically substantiates the principle of homeopathic cure. Although the rebound phenomenon is an adverse event studied by modern pharmacology, it is not known by health care professionals, thus depriving doctors of knowledge indispensable for safe management of drugs.
