Who judges medical practice?

Lawsuits due to patient perception of inappropriate medical actions are a growing reality in medical practice, which entails widespread concern in the medical community. Lawsuits often entail additional circumstances beyond the primary concern of preventing or sanctioning acts of medical negligence. CETREMI proposes various recommendations aimed at legal and medical professionals to improve this circumstance and avoid harming the doctor-patient relationship.

Las demandas judiciales por la percepción del paciente de una actuación médica inadecuada son una realidad creciente en la práctica médica, la cual entraña una preocupación extendida en el gremio médico. Las demandas judiciales frecuentemente conllevan circunstancias adicionales a la primaria preocupación de prevenir o sancionar actos de negligencia médica. CETREMI emite algunas recomendaciones a los profesionales jurídicos y médicos para mejorar esta situación y evitar daños en la relación médico-paciente.

New interaction modalities between the pharmaceutical industry and physicians.

Due to sanitary restrictions secondary to the COVID-19 pandemic, various interactions between the pharmaceutical industry and physicians have changed. One of them has been the method for promoting medicinal products through academic meetings around diseases of financial interest. A recent modality has been unilateral promotion by the pharmaceutical industry through academic events with the invitation of so-called "experts" for the promotion of a specific drug. These meetings are often biased not towards optimal care of a disease, but rather towards commercial promotion of a specific drug, which may or may not be the best option, without considering associated therapeutic alternatives. The Committee of Ethics and Transparency in the Physician-Industry Relationship, of the National Academy of Medicine, analyzes this new circumstance and proposes some considerations to the medical community.

Debido a las restricciones sanitarias secundarias a la pandemia de COVID-19, diversas interacciones entre la industria farmacéutica y los médicos cambiaron. Una de ellas ha sido el método promocional de medicamentos a través de reuniones académicas en torno a padecimientos de interés financiero. Una modalidad reciente ha sido la promoción unilateral de un fármaco determinado por parte de la industria farmacéutica por medio de eventos académicos con la invitación de aparentes "expertos". Estas reuniones frecuentemente están sesgadas no hacia la atención óptima de un padecimiento, sino a la promoción comercial de un medicamento específico que pudiera o no ser la mejor opción o sin la consideración de alternativas terapéuticas asociadas. El Comité de Ética y Transparencia en la Relación Médico-Industria, de la Academia Nacional de Medicina de México, analiza esta nueva circunstancia y propone algunas consideraciones a la comunidad médica.

Importance of the list of essential medicines in medical prescription.

The implementation of an essential medicines list in health institutions allows acquiring and administering a long list of drugs that offers treatment alternatives to physicians, as well as a collegiate academic description of indications, doses, side effects, interactions and cost-benefit analyses, thus facilitating medical prescription and administration of health products. The Committee of Ethics and Transparency in the Physician-Industry Relationship issues several recommendations for optimizing the benefits generated by essential medicines lists.La implementación en instituciones de salud de un cuadro básico permite adquirir y administrar una larga lista de medicamentos que presenta a los médicos las alternativas de tratamiento, así como la descripción académica colegiada de indicaciones, dosis, efectos secundarios, interacciones y análisis de costo-beneficio, con lo que se facilita la prescripción médica y la administración de insumos para la salud. El Comité de Ética y Transparencia en la Relación Médico-Industria emite diversas recomendaciones para la optimización de los beneficios generados por los cuadros básico de medicamentos.

Medical prescription: conditioned reflex or conscious reflection?

Writing a prescription or indicating a treatment is usually the last part of medical consultation. This crucial process can be undermined by multiple factors such as limited prescriptive ability, overwork, and lack of reflection or time. Insufficient information about the patient or the treatment affects the prescriptive process and leads to errors that can be serious for patient health. The National Academy of Medicine, in line with the World Health Organization, emphasizes the relevance of making the prescriptive process a reflective exercise.Extender una receta o indicar un tratamiento suele ser la última parte de la consulta médica. Este proceso crucial puede desvirtuarse debido a múltiples factores como capacidad prescriptiva limitada, exceso de trabajo y falta de reflexión o tiempo. La información insuficiente acerca del paciente o del tratamiento afecta el proceso prescriptivo y propicia errores que pueden ser graves para la salud del enfermo. La Academia Nacional de Medicina, en consonancia con la Organización Mundial de la Salud, hace énfasis en hacer del proceso prescriptivo un ejercicio de reflexión.

Self-medication and self-prescription.

Self-medication and self-prescription are actions undertaken by patients; the former, as an element of self-care that involves over-the-counter drugs, and the latter, as a violation of the Statute of Health, since it includes drugs that can only be dispensed with a medical prescription. All the drawbacks that have been attributed to self-medication are actually associated with self-prescription.La automedicación y la autoprescripción son acciones de los pacientes; la primera como elemento del autocuidado que involucra medicamentos de venta libre y la segunda como una violación a la ley de salud, pues comprende medicamentos que solo pueden expenderse con receta. Todos los inconvenientes que se han atribuido a la automedicación en realidad lo son de la autoprescripción.

Recommendations for the sale and promotion of dermocosmetic treatments at the office.

A novel chapter in current medical settings is the promotion and attention of esthetic aspects rather than health issues by health professionals. The human aspiration related to the search for personal beauty has generated new scenarios in medical practice. The Committee on Ethics and Transparency in the Physician-Industry Relationship (CETREMI) of the National Academy of Medicine of Mexico has analyzed this phenomenon and has issued recommendations directed both to medical professionals and to producers and potential consumers of esthetic procedures.

Un capítulo novedoso es la atención y promoción por parte de médicos especialistas de aspectos relacionados con procedimientos estéticos, más que con la salud. La aspiración humana de la búsqueda de la belleza personal ha generado nuevos escenarios en la labor médica. El Comité de Ética y Transparencia en la Relación Médico Industria (CETREMI) de la Academia Nacional de México ha revisado esta circunstancia y emite recomendaciones tanto a los médicos como a los productores y potenciales consumidores de procedimientos estéticos.

Conflictos de intereses en medicina. Recomendaciones del CETREMI.

Conflicts of interest are situations in which judgment and integrity of medical decisions or actions are influenced by a secondary interest, often of an economic nature. The Committee of Ethics and Transparency in the Physician-Industry Relationship of the National Academy of Medicine of Mexico recognizes that these conflicts occur in health professionals' daily life, but also in public and private institutions that provide health services, as well as in the academy and in research activities. Therefore, it is necessary to identify conflicting situations and always act in accordance with the patient's interest.

Los conflictos de interés son situaciones en las que el juicio y la integridad de las decisiones o acciones médicas son influidas por un interés secundario, frecuentemente de tipo económico. El Comité de Ética y Transparencia en la Relación Médico-­Industria de la Academia Nacional de Medicina de México reconoce que estos conflictos ocurren en la vida diaria de los profesionales de la salud, pero también en las instituciones de servicios de salud públicas y privadas, así como en la academia y en la investigación. Por ello, es necesario identificar situaciones de conflicto y actuar siempre de acuerdo con el interés del paciente.

Libertad de prescripción médica.

Doctors require flexibility for prescription. However, some limits are laid down both by current knowledge and by restrictions imposed by access and rules and regulations. The Committee for Ethics and Transparency in the Physician-Industry Relationship (CETREMI) of the National Academy of Medicine proposes several suggestions to help patients, which include the selection of the best alternatives for each case, formalization of prescription standards variations (doses, drug indications, etc.) written down in the medical records, and avoidance of fashions, untested novelties, argumentations solely based on advertising or commercial promotion and conflicts of interest.

Los médicos requieren flexibilidad para sus prescripciones. Sin embargo, algunos límites están marcados tanto por el conocimiento vigente como por las restricciones de acceso, normas y reglamentos. El Comité de Ética y Transparencia en la Relación Médico-Industria (CETREMI) propone varias sugerencias para ayudar a los pacientes, que incluyen la selección de las mejores alternativas para cada caso, la protocolización de variaciones a los estándares de prescripción (dosis, indicaciones, etcétera) por escrito en el expediente y eludir modas, novedades no probadas, argumentos simplemente publicitarios o promocionales y conflictos de interés.

Importancia de la investigación clínica independiente en la medicina: dificultades y recomendaciones.

Clinical research is the most important tool for the identification of diagnostic and therapeutic strategies that derive in higher efficacy and safety. Despite its significance, successful implementation of clinical research faces numerous difficulties, with one the most relevant being limited availability of resources for the performance of independent clinical trials. Generally, the pharmaceutical industry absorbs the costs associated with most clinical trials; however, this can generate dissociation between subjects of interest and health priorities when economic interest is the main driver of these protocols. In addition to the relevant role played by the pharmaceutical industry, it is important that government agencies favor adequate conditions, both in economic and regulatory aspects, for the implementation of independent clinical research that addresses subjects of medical and therapeutic interest, even if it does not generate corporate economic benefits.

La investigación clínica es la herramienta de mayor importancia para la identificación de estrategias diagnósticas y terapéuticas que deriven en mayor eficacia y seguridad. A pesar de su trascendencia, la implementación exitosa de la investigación clínica presenta numerosas dificultades; entre las más relevantes se encuentra la poca disponibilidad de recursos para realizar ensayos clínicos independientes. Por lo general, la industria farmacéutica absorbe los costos asociados con la mayoría de los ensayos clínicos, sin embargo, esto puede generar una disociación entre los temas de interés y las prioridades en salud, al existir interés económico como principal motivación de estos protocolos. Además del papel relevante de la industria farmacéutica, es importante que las instancias gubernamentales favorezcan las condiciones, tanto económicas como regulatorias, para la implementación de investigación clínica independiente, que aborde temas de interés médico y terapéutico, aunque no genere beneficios económicos empresariales.

Methylprednisolone Administration Following Spinal Cord Injury Reduces Aquaporin 4 Expression and Exacerbates Edema.

Spinal cord injury (SCI) is an incapacitating condition that affects motor, sensory, and autonomic functions. Since 1990, the only treatment administered in the acute phase of SCI has been methylprednisolone (MP), a synthetic corticosteroid that has anti-inflammatory effects; however, its efficacy remains controversial. Although MP has been thought to help in the resolution of edema, there are no scientific grounds to support this assertion. Aquaporin 4 (AQP4), the most abundant component of water channels in the CNS, participates in the formation and elimination of edema, but it is not clear whether the modulation of AQP4 expression by MP plays any role in the physiopathology of SCI. We studied the functional expression of AQP4 modulated by MP following SCI in an experimental model in rats along with the associated changes in the permeability of the blood-spinal cord barrier. We analyzed these effects in male and female rats and found that SCI increased AQP4 expression in the spinal cord white matter and that MP diminished such increase to baseline levels. Moreover, MP increased the extravasation of plasma components after SCI and enhanced tissue swelling and edema. Our results lend scientific support to the increasing motion to avoid MP treatment after SCI.

Mexican Multicenter Experience of Metastatic Spinal Disease.

Background Spinal metastatic disease is a silent progressive cancer complication with an increasing prevalence worldwide. The spine is the third most common site where solid tumors metastasize. Complications involved in spinal metastasis include root or spinal cord compression, progressing to a declining quality of life as patient autonomy reduces and pain increases. The main objective of this study is to report the incidence of patients and typology of spinal metastases in three reference centers in Mexico. Methodology Retrospective cohorts of patients diagnosed with spinal metastases from January 2010 to February 2017 at the National Cancer Institute, National Rehabilitation Institute, and the Traumatology and Orthopedics Hospital "Lomas Verdes" in Mexico City were analyzed. Results A total of 326 patients (56% males) with spinal metastases were reported. The mean age was 58.06 ± 14.05 years. The main sources of spinal metastases were tumors of unknown origin in 53 (16.25%) cases, breast cancer in 67 (20.5%) cases, prostate cancer in 59 (18%) cases, myeloma in 24 (7.4%) cases, and lung cancer in 23 (7.1%) cases. Conclusions The data obtained in this analysis delivers an updated standpoint on Mexico, providing the opportunity to distinguish the current data from global references. Collecting more epidemiological information for better recording of cancer and its associated complications, as well as further studies on them, is necessary.

The impact of body mass index and central obesity on the spino-pelvic parameters: a correlation study.

INTRODUCTION: Obesity is an increasing problem of epidemic proportion, and it is associated with various musculoskeletal disorders, including impairment of the spine. However, the relationship between obesity and spino-pelvic parameters remains to date unsupported by an objective measurement of the mechanical behavior of the spino-pelvic parameters depending on body mass index (BMI) and the presence of central obesity. Such analysis may provide a deeper understanding of this relationship. PURPOSE: To assess whether BMI and central obesity are associated with modifications on spino-pelvic parameters and determine if exists any correlation between BMI and obesity with the type of lumbar lordosis (LL). METHODS: A cross-sectional study with 200 participants was conducted. Parameters measured were LL, pelvic tilt, sacral slope, and pelvic incidence (PI), using lumbosacral radiographs in lateral view. Subjects were classified depending on BMI. In a secondary analysis, the subjects were categorized into two groups depending on the presence or not of elevated abdominal circumference. The categorical variables were compared using Chi-square test, and the mean values were compared using ANOVA and student t test. A Spearman correlation test was used to analyze the correlation between BMI categories and LL types. RESULTS: From the total of participants, there were 51 (25.5 %) normal weight subjects, 93 (46.5 %) overweight, and 56 (28 %) obese individuals. The spino-pelvic parameters among these groups are practically equal. The correlation between the different BMI categories and LL types is poor 0.06 (P = 0.34). In a secondary analysis, grouping the participants in obese and non-obese, the results showed that obesity is modestly positively associated with increasing of spino-pelvic parameters values, in particular with PI (P = 0.078). The comparison made between the presence or not of central obesity, interestingly did not show significant differences. CONCLUSIONS: Despite the results did not reach statistically significant differences, the results indicate that the obese spine is slightly different from the non-obese spine. Therefore, this relationship deserves future attention.

Single Dose of Tranexamic Acid Effectively Reduces Blood Loss in Patients Undergoing Spine Surgery: A Prospective Randomized Controlled Trial.

OBJECTIVE: To evaluate the efficacy of oral administration of tranexamic acid (TXA) in spine surgery to achieve blood loss reduction. METHODS: Sixty patients undergoing major surgery of the spine were randomly assigned into 2 groups. Group 1 was assigned as the control group and the other group comprised patients who received oral administration of TXA 2 hours before surgery. Outcome measures included intraoperative blood loss, postoperative blood loss, hematologic parameters, blood transfusion needed, and surgical complications. RESULTS: Sixty patients linked up with the inclusion criteria. Intraoperative blood loss was significantly lower in the TXA oral group than in the control group; total blood loss in the TXA group was 930.66 ± 614 mL, which was lower than in the control group, with 1075.66 ± 956.11 mL. The mean reduction of hemoglobin was almost the same in both groups. Similarly, the total transfusion package received was lower, and the number of complications and length of stay were akin in both groups. A logistic regression model was performed with patients who had blood loss >1000 mL and surgery time >230 minutes. This result was related to the risk of bleeding, with an odds ratio of 1.31, 95% confidence interval, 1.004-1.023, P = 0.004, independent of the group. CONCLUSIONS: Oral TXA is as an effective measure for reducing total blood loss among patients undergoing elective spine surgery.
