Comprehensive GC-MS Measurement of Amino Acids, Metabolites, and Malondialdehyde in Metformin-Associated Lactic Acidosis at Admission and during Renal Replacement Treatment.

Metformin is the most widely used drug in type 2 diabetes. Regular metformin use has been associated with changes in concentrations of amino acids. In the present study, we used valid stable-isotope labeled GC-MS methods to measure amino acids and metabolites, including creatinine as well as malondialdehyde (MDA), as an oxidative stress biomarker in plasma, urine, and dialysate samples in a patient at admission to the intensive care unit and during renal replacement treatment because of metformin-associated lactic acidosis (MALA, 21 mM lactate, 175 µM metformin). GC-MS revealed lower concentrations of amino acids in plasma, normal concentrations of the nitric oxide (NO) metabolites nitrite and nitrate, and normal concentrations of MDA. Renal tubular reabsorption rates were altered on admission. The patient received renal replacement therapy over 50 to 70 h of normalized plasma amino acid concentrations and their tubular reabsorption, as well as the tubular reabsorption of nitrite and nitrate. This study indicates that GC-MS is a versatile analytical tool to measure different classes of physiological inorganic and organic substances in complex biological samples in clinical settings such as MALA.

GC-MS analysis of 4-hydroxyproline: elevated proline hydroxylation in metformin-associated lactic acidosis and metformin-treated Becker muscular dystrophy patients.

Metformin (N,N-dimethylbiguanide), an inhibitor of gluconeogenesis and insulin sensitizer, is widely used for the treatment of type 2 diabetes. In some patients with renal insufficiency, metformin can accumulate and cause lactic acidosis, known as metformin-associated lactic acidosis (MALA, defined as lactate ≥ 5 mM, pH < 7.35, and metformin concentration > 38.7 µM). Here, we report on the post-translational modification (PTM) of proline (Pro) to 4-hydroxyproline (OH-Pro) in metformin-associated lactic acidosis and in metformin-treated patients with Becker muscular dystrophy (BMD). Pro and OH-Pro were measured simultaneously by gas chromatography-mass spectrometry before, during, and after renal replacement therapy in a patient admitted to the intensive care unit (ICU) because of MALA. At admission to the ICU, plasma metformin concentration was 175 µM, with a corresponding lactate concentration of 20 mM and a blood pH of 7.1. Throughout ICU admission, the Pro concentration was lower compared to healthy controls. Renal excretion of OH-Pro was initially high and decreased over time. Moreover, during the first 12 h of ICU admission, OH-Pro seems to be renally secreted while thereafter, it was reabsorbed. Our results suggest that MALA is associated with hyper-hydroxyprolinuria due to elevated PTM of Pro to OH-Pro by prolyl-hydroxylase and/or inhibition of OH-Pro metabolism in the kidneys. In BMD patients, metformin, at the therapeutic dose of 3 × 500 mg per day for 6 weeks, increased the urinary excretion of OH-Pro suggesting elevation of Pro hydroxylation to OH-Pro. Our study suggests that metformin induces specifically the expression/activity of prolyl-hydroxylase in metformin intoxication and BMD.

Deformation characteristics and mechanism of Mala paleo-landslide during the Miaowei reservoir initial impoundment period.

This study employs a multifaceted approach, encompassing field investigations, borehole surveys, surface deformation displacement monitoring, deep-seated deformation monitoring, and numerical simulation analysis, to conduct an exhaustive examination of the deformation processes and characteristics exhibited by the Mala Landslide. The findings elucidate a close correlation between the deformation of the Mala Landslide and the elevation of the reservoir water level. During the escalation of the reservoir water level, the landslide body progressively developed surface cracks, spanning from the frontal edge to the rear edge. The centre of the sliding body is situated in the central-lower downstream region, and presently, the landslide is undergoing a phase of comprehensive creep deformation. Due to the reservoir water level fluctuation rate being greater than the permeability coefficient, the deformation of the landslide displays a delayed response. As the reservoir water level reaches 1401 m during high-water operation, the two important ingredients, the buoyancy weight reduction effect and the influence of submerged reservoir water, significantly reduce the sliding resistance of the sliding mass, thereby exacerbating the deformation of the landslide. Following a comprehensive analysis of the findings, it can be firmly concluded that this landslide conforms to the characteristic traits of a typical buoyant force reduction type-retrogressive type landslide.

Abstract Objective To understand the perception of access to food and food quality for the street population. Methods This qualitative descriptive study was performed in a Reference Center for the Homeless Population in the south-central region of Belo Horizonte (MG). A semi-structured script was used to conduct interviews with 18 participants. Data collection occurred between December 2020 and January 2021. The thematic analysis of the material, as proposed by Bardin, made it possible to elaborate three empirical categories. Results The public interviewed was male, with a mean age of 43 years, and a mean time on the streets of 44.6 months. Access to food came from donations, meals at government institutions, and acquisition when income was available. Difficulties were reported regarding the quantity and quality of food, acquisition of meals on weekends, feelings of fear and anguish in the face of hunger, lack of food, and social stigma, which were aggravated by COVID-19. Conclusion As in this scenario of social inequalities the access to food is not guaranteed, implementing public policies of social protection is necessary to guarantee basic rights.

Chatbots, generative AI, and scholarly manuscripts: WAME recommendations on chatbots and generative artificial intelligence in relation to scholarly publications

This statement revises our earlier "WAME Recommendations on ChatGPT and Chatbots in Relation to Scholarly Publications" (January 20, 2023). The revision reflects the proliferation of chatbots and their expanding use in scholarly publishing over the last few months, as well as emerging concerns regarding lack of authenticity of content when using chatbots. These recommendations are intended to inform editors and help them develop policies for the use of chatbots in papers published in their journals. They aim to help authors and reviewers understand how best to attribute the use of chatbots in their work and to address the need for all journal editors to have access to manuscript screening tools. In this rapidly evolving field, we will continue to modify these recommendations as the software and its applications develop.

Esta declaración revisa las anteriores "Recomendaciones de WAME sobre ChatGPT y Chatbots en Relation to Scholarly Publications" (20 de enero de 2023). La revisión refleja la proliferación de chatbots y su creciente uso en las publicaciones académicas en los últimos meses, así como la preocupación por la falta de autenticidad de los contenidos cuando se utilizan chatbots. Estas recomendaciones pretenden informar a los editores y ayudarles a desarrollar políticas para el uso de chatbots en los artículos sometidos en sus revistas. Su objetivo es ayudar a autores y revisores a entender cuál es la mejor manera de atribuir el uso de chatbots en su trabajo y a la necesidad de que todos los editores de revistas tengan acceso a herramientas de selección de manuscritos. En este campo en rápida evolución, seguiremos modificando estas recomendaciones a medida que se desarrollen el software y sus aplicaciones.

High risk and low prevalence diseases: Metformin toxicities.

INTRODUCTION: Metformin toxicity is a rare but serious condition that carries with it a high rate of morbidity and mortality. OBJECTIVE: This review highlights the pearls and pitfalls of metformin toxicity, including diagnosis, initial resuscitation, and management in the emergency department (ED) based on current evidence. DISCUSSION: Metformin is a common medication used for treatment of diabetes mellitus. Metformin toxicity is a spectrum of conditions that may be differentiated into three subgroups: metformin-associated lactic acidosis (MALA), metformin-induced lactic acidosis (MILA), and metformin-unrelated lactic acidosis (MULA). MILA is a condition found predominantly in patients chronically taking metformin or those with large acute overdoses. Conversely, MULA occurs in patients on metformin but with a critical illness stemming from a separate cause. MALA is rare but the most severe form, with mortality rates that reach 50%. Differentiating these entities is difficult in the ED setting without obtaining metformin levels. Patients with metformin toxicity present with nonspecific gastrointestinal symptoms and vital sign abnormalities. Laboratory analysis will reveal a high lactate with anion gap metabolic acidosis. Patients presenting with elevated lactate levels in the setting of metformin use should be considered at risk for the most severe form, MALA. Patients with MALA require aggressive treatment with intravenous fluids, treatment of any concomitant condition, and early consideration of hemodialysis, along with specialist consultation such as nephrology and toxicology. CONCLUSIONS: An understanding of metformin toxicity can assist emergency clinicians in diagnosing and managing this potentially deadly disease.

Objetivo: Conocer la percepción sobre la violencia obstétrica en estudiantes de ciencias de la salud. Método: Diseño transversal en el que se empleó el cuestionario validado PercOV-S (Percepción sobre la Violencia Obstétrica de Estudiantes). El cuestionario se ofreció al alumnado que participó en el I Congreso de Medicina Feminista del CEEM (Consejos Estatal de Estudiantes de Medicina) celebrado el 12 de marzo de 2021. Este cuestionario se envió de manera online a través de Google Forms®. Resultado: La puntuación media obtenida en el total de la escala fue de 3,83 puntos (DS=0,61). Para la dimensión de la violencia obstétrica protocolizada-visible la puntuación media fue de 2,79 puntos (DS=0,84) y para la dimensión de violencia obstétrica no protocolizada-invisible se obtuvo una media de 4,16 puntos (DS=0,61). La puntuación global del cuestionario mostró diferencias estadísticamente significativas con la variable ámbito (p=0,019), curso (p=0,008), trato en función de la etnia (p=0,008), trato en función del status socioeconómico, condición de inmigrante (p<0,001) y conocimientos previos sobre el concepto de violencia obstétrica (p<0,001). Conclusiones: Los datos evidencian una marcada sensibilidad generalizada de la muestra hacia la temática de la violencia obstétrica, especialmente, frente a las características étnicas de las mujeres. Asimismo, se observa la necesidad de generar formación ético-actitudinal frente a la violencia obstétrica.(AU)

To measure of perception of obstetric violence in students of health sciences. Method: Cross-sectional design in which the validated questionnaire PercOV-S (Perception of Student Obstetric Violence) was used. The questionnaire was offered to the students who participated in the I Congress of Feminist Medicine of the CEEM (State Councils of Medical Students) held on March 12, 2021. This questionnaire was sent online through Google Forms. Results: The mean score obtained on the total scale was 3.83 scores (SD=0.61). For the dimension of protocolized-visible obstetric violence, the mean score is 2.79 points (SD=0.84) and for the dimension of non-protocolized-invisible obstetric violence, a mean of 4.16 points is obtained (SD=0.61). The global score of the displayed question differs statistically significantly with the variable scope (p=0.019), course (p=0.008), treatment according to ethnicity (p=0.008), treatment according to socioeconomic level, immigrant status (p <0.001), and prior knowledge about the concept of obstetric violence (p <0.001). Conclusions: The data show a marked generalised sensitivity of the sample to the issue of obstetric violence, especially with regard to the ethnic characteristics of the women. Likewise, the need to generate ethical-attitudinal training in the response to obstetric violence is observed.(AU)

A case of metformin-associated lactic acidosis with cardiogenic and vasoplegic shock supported by ECPella.

Metfomin-associated lactic acidosis (MALA) is a rare but life-threatening complication of metformin use. We present a case of MALA with concurrent cardiogenic and vasoplegic shock which was successfully supported by ECPella (concurrent use of VA-ECMO and Impella). Early recognition, aggressive hemodynamic support with ECPella and early hemodialysis can be life-saving. Monitoring of both lactate and SvO2 trends can help understand the response to treatment.

Mielopatía por déficit de cobre: serie de casos y revisión de la literatura / Myelopathy due to copper deficiency: A case series and review of the literature

El déficit de cobre puede presentarse como una mielopatía y manifestarse como una ataxia sensorial secundaria a una desmielinización de los cordones posteriores de la médula espinal. Puede acompañarse de citopenias, principalmente anemia y leucopenia. Se presenta una serie de casos de tres pacientes con mielopatía por déficit de cobre, diagnosticados y manejados desde el año 2020 al 2022 en un hospital universitario de alta complejidad en Colombia. Dos de los casos eran mujeres. El rango de edad fue entre 57 y 68 años. En los tres casos, los niveles séricos de cobre estaban disminuidos y en dos de ellos, se descartaron diferentes causas de mielopatía que afectan los cordones posteriores de la médula espinal como el déficit de vitamina B12, vitamina E y ácido fólico, tabes dorsal, mielopatía por virus de la inmunodeficiencia humana, esclerosis múltiple e infección por el virus linfotrópico humano de tipo I y II, entre otras. Sin embargo, un paciente tenía deficiencia de vitamina B12 asociada con de cobre en el momento del diagnóstico de la mielopatía. En los tres casos hubo ataxia sensitiva y en dos, la paraparesia fue el déficit motor inicial. Se deben incluir siempre la determinación de los niveles de cobre dentro del abordaje diagnóstico de todo paciente con enfermedad gastrointestinal crónica, con diarrea crónica, síndrome de mala absorción o reducción significativa de la ingestión en la dieta, y que desarrolle síntomas neurológicos sugestivos de compromiso de los cordones, ya que se ha reportado que el retraso en el diagnóstico de las mielopatías se asocia con pobres desenlaces neurológicos.

Copper deficiency can present as myelopathy by the manifestation of sensory ataxia, secondary to demyelination of the posterior cords of the spinal cord, accompanied by cytopenia, mainly anemia, and leukopenia. Case series study of three patients with myelopathy due to copper deficiency, diagnosed and managed from 2020 to 2022 in a highly complex university hospital in Colombia. Regarding gender, two cases were female patients. The age range was between 57 and 68 years. In all three cases serum copper levels were decreased, and in two of these, different causes of myelopathy affecting the posterior cords of the spinal cord were ruled out, such as vitamin B12, vitamin E and folic acid deficiency, tabes dorsalis, myelopathy due to human immunodeficiency virus, multiple sclerosis and infection by the human lymphotropic virus type I and II, among others. However, at the moment of the myelopathy diagnosis, one patient had vitamin B12 deficiency associated with copper insufficiency. All three cases presented sensory ataxia, and in two, paraparesis was the initial motor deficit. The diagnostic approach must include copper levels assessment in every case of patients with chronic gastrointestinal pathology, chronic diarrhea, malabsorption syndrome, or significant reduction in dietary intake; and the development of neurological symptoms that may suggest cord involvement. It has been reported that a delay in diagnosis can lead to poor neurological outcomes.

Una Revisión de los tipos de Fraude Científico más Frecuentes / A Review of the most frequent types of Scientific Fraud

La presión que existe hoy por publicar ha llevado a que muchos investigadores cometan malas conductas científicas, siendo el fraude la más grave de todas. Este ocurre en forma de fabricación, falsificación, plagio, problemas de autoría, manipulación de imágenes y publicaciones redundantes. El fraude científico se define como una tergiversación deliberada por parte de alguien que conoce la verdad. En la historia de la humanidad se han conocido importantes casos de fraude científico, dentro de ellos se pueden destacar: el hombre de Piltdown, caso Shinichi Fujimura, el escándalo de las vacunas, caso Pearce, el caso Yoshitaka Fujii, entre otros. Con el objetivo de neutralizar el fraude, se han desarrollado diferentes estrategias dirigidas a detectarlo, dentro de ellas encontramos: evaluación mediante pares evaluadores, programas de Conducta de Investigación Responsable (RCR), regulaciones que la misma comunidad científica realiza, donde encontramos la fundación PubPeer y el blog For Better Science. Del mismo modo, se han impuesto diferentes medidas para contrarrestar el fraude, tales como: transparencia de las presiones y oportunidades, disponibilidad pública de los datos que sustentan la hipótesis y denuncia pública de los fraudes científicos. El impacto de un fraude trae consecuencias importantes para la ciencia, estudiar a partir de información falsa o errónea conlleva a un gran retroceso en los avances científicos del mundo actual. Es responsabilidad de cada uno ser consciente de lo que se escribe y lo que se lee, ya que como se sabe, esa es la única manera de combatirlo. Como investigadores somos responsables de actuar éticamente en nuestras investigaciones y tener conocimiento de las medidas que existen hoy para detectar y combatir el fraude científico.

The pressure to publish today has led many researchers to commit scientific misconduct, fraud being the most serious of all. This occurs in the form of fabrication, falsification, plagiarism, authorship problems, image manipulation, and redundant posting. Scientific fraud is defined as deliberate misrepresentation by someone who knows the truth. In the history of humanity, important cases of scientific fraud have been known, among them the following can be highlighted: the Piltdown man, the Shinichi Fujimura case, the vaccine scandal, the Pearce case, the Yoshitaka Fujii case, among others. In order to neutralize fraud, different strategies have been developed to detect it, among them we find: evaluation by peer reviewers, Responsible Research Conduct (RCR) programs, regulations that the scientific community itself carries out, where we find the PubPeer Foundation and the For Better Science blog. Similarly, different measures have been imposed to counteract fraud, such as: transparency of pressures and opportunities, public availability of the data that support the hypothesis, and public denunciation of scientific fraud. The impact of a fraud has important consequences for science, studying from false or wrong information leads to a great setback in scientific advances in the world today. It is the responsibility of each one to be aware of what is written and what is read, since as is known, that is the only way to combat it. As researchers we are responsible for acting ethically in our research and being aware of the measures that exist today to detect and combat scientific fraud.

Estudio mediante cuestionarios anónimos de las fallas en la integridad científica del personal de investigación latinoamericano, 2001-2020

el objetivo de este trabajo es analizar fallas a la integridad científica por parte de personal de investigación latinoamericano. Metodología: se realizaron cuestionarios anónimos y voluntarios después de tratar este tema en 121 cursos de redacción científica / taller de tesis dictados en Latinoamérica, sobre todo en Argentina, durante 20 años (2001-2020). Resultados: las 2064 respuestas válidas mostraron que un 60 % tenía cinco o más años de egreso, 48,6 % señalaron coautoría indebida y 28,9 % que su nombre fue omitido de publicaciones. Un 24,9 % reconoció haber cometido alguna clase de mala conducta en su carrera. La coacción a que fue sometido para que lo hiciera fue reconocida por un 56,7 %. El 60,7 % de las 512 personas ignoraba que era un error. La coautoría indebida fue la mala conducta más frecuente (46 %), seguida de plagio y falseamiento de datos. En relatos conocidos de primera mano se destacan: publicación en salamín, duplicación y robo de datos, así como soborno y manipulación de imágenes. Ninguna de las personas que tomaron cursos previos de formación en bioética (0/560) cometieron motu propio actos inadecuados. Conclusión: el personal científico comete un porcentaje relativamente elevado de fallas a la integridad científica; impartir cursos de integridad científica tiene un fuerte rol en el autocontrol para evitarlas.

Objective: This work aims to analyze failures in scientific integrity on the part of Latin American research personnel. Methodology: anonymous and voluntary questionnaires were carried out after dealing with this topic in 121 scientific writing courses/thesis workshops in Latin America, mainly in Argentina, for 20 years (2001-2020). Results: The 2064 valid responses showed that 60% had five or more years of graduation, 48.6% indicated improper co-authorship, and 28.9% that their name was omitted from publications. 24.9% acknowledged having omitted their name from publications. Some 24.9% acknowledged having committed some misconduct in their career. The coercion to which he was subjected to do so was recognized by 56.7%. 60.7 % of the 512 people were unaware that it was a mistake. Misconduct was the most frequent misconduct (46 %), followed by plagiarism and misrepresentation of data. In first-hand accounts, salami publication, data duplication, theft, bribery, and image manipulation stand out. None of the persons who took previous bioethics training courses (0/560) committed inappropriate acts of their own accord. Conclusion: scientific personnel commits a relatively high percentage of scientific integrity failures; providing scientific integrity courses has a decisive role in self-monitoring to avoid them.

Malassezia sympodialis Mala s 1 allergen is a potential KELCH protein that cross reacts with human skin.

Malassezia are the dominant commensal yeast species of the human skin microbiota and are associated with inflammatory skin diseases, such as atopic eczema (AE). The Mala s 1 allergen of Malassezia sympodialis is a ß-propeller protein, inducing both IgE and T-cell reactivity in AE patients. We demonstrate by immuno-electron microscopy that Mala s 1 is mainly located in the M. sympodialis yeast cell wall. An anti-Mala s 1 antibody did not inhibit M. sympodialis growth suggesting Mala s 1 may not be an antifungal target. In silico analysis of the predicted Mala s 1 protein sequence identified a motif indicative of a KELCH protein, a subgroup of ß-propeller proteins. To test the hypothesis that antibodies against Mala s 1 cross-react with human skin (KELCH) proteins we examined the binding of the anti-Mala s 1 antibody to human skin explants and visualized binding in the epidermal skin layer. Putative human targets recognized by the anti-Mala s 1 antibody were identified by immunoblotting and proteomics. We propose that Mala s 1 is a KELCH-like ß-propeller protein with similarity to human skin proteins. Mala s 1 recognition may trigger cross-reactive responses that contribute to skin diseases associated with M. sympodialis.

METHOD: Cross-sectional design in which the validated questionnaire PercOV-S (Perception of Student Obstetric Violence) was used. The questionnaire was offered to the students who participated in the I Congress of Feminist Medicine of the CEEM (State Councils of Medical Students) held on March 12, 2021. This questionnaire was sent online through Google Forms. RESULTS: The mean score obtained on the total scale was 3.83 scores (SD=0.61). For the dimension of protocolized-visible obstetric violence, the mean score is 2.79 points (SD=0.84) and for the dimension of non-protocolized-invisible obstetric violence, a mean of 4.16 points is obtained (SD=0.61). The global score of the displayed question differs statistically significantly with the variable scope (p=0.019), course (p=0.008), treatment according to ethnicity (p=0.008), treatment according to socioeconomic level, immigrant status (p<0.001), and prior knowledge about the concept of obstetric violence (p<0.001). CONCLUSIONS: The data show a marked generalised sensitivity of the sample to the issue of obstetric violence, especially with regard to the ethnic characteristics of the women. Likewise, the need to generate ethical-attitudinal training in the response to obstetric violence is observed.

Severe lactic acidosis with euglycemic diabetic ketoacidosis due to metformin overdose.

Metformin-associated lactic acidosis is a well-known metformin treatment complication; however, the development of euglycemic diabetic ketoacidosis (euDKA) has rarely been reported. Here we report a case of lactic acidosis and euDKA after metformin overdose. A 57-year-old female patient was transferred to our hospital with severe metabolic acidosis and acute kidney injury. She had type 2 diabetes mellitus and was on oral antidiabetic therapy of vildagliptin metformin hydrochloride daily. On the admission day, she had committed suicide by overdosing 50 tablets of vildagliptin metformin hydrochloride, which was equivalent to 25,000 mg of metformin and 2500 mg of vildagliptin. She had severe lactic acidosis 5 h after overdosing. However, after 34 h of overdosing, serum lactate levels decreased while serum anion gap levels increased. She received single hemodialysis treatment. Serum total ketone bodies, ß-hydroxybutyrate acetoacetic acid, and acetone were increased even after hemodialysis treatment. Her blood glucose levels have never exceeded 250 mg/dL since admission. Therefore, we considered that the cause of metabolic acidosis in this patient was not only lactic acidosis but also euDKA. The causes of euDKA in our patient might be hepatic production of ketone bodies due to metformin overdose in addition to type 2 diabetes mellitus, starvation, infection, and stressful physical conditions such as vomiting and diarrhea. We propose that not only lactic acidosis but also ketoacidosis is one of the important pathological conditions in patients with metformin overdose.

Toxicokinetics of metformin overdose treated with CVVHDF.

A 53-year-old man died following a reported ingestion of 80 g of his metformin tablets resulting in severe, refractory shock and metformin-associated lactic acidosis. His peak serum metformin concentration was 53 µg/mL (therapeutic range 1-2 µg/mL), peak lactic acid concentration was 49.7 mmol/L, and arterial pH nadir was 7.06. He died despite vasopressors and renal replacement therapy [RRT; both intermittent hemodialysis (IHD) and continuous venovenous hemodiafiltration (CVVHDF)]. Serial metformin concentrations during CVVHDF suggested a half-life of 33-h. Similar to previous reports of RRT for metformin toxicity, CVVHDF appears to provide first-order elimination of metformin.

Social control, transparency, accountability, and scientific integrity in medical research / Control social, transparencia, responsabilidad y integridad de la investigación médica / CONTROLE SOCIAL, TRANSPARÊNCIA, INTEIREZA CIENTÍFICA E RESPONSABILIDADE EM PESQUISAS MÉDICAS

The CEP/CONEP System, submitted to social control, is responsible for the ethical approval of research in Brazil to protect research participants. The Informed Consent Form (ICF) is the public document that implements the protection of participants. The paper presents two cases of medical research in the Amazon region on malaria and the use of chloroquine for treating COVID-19. The participants were uninformed in the ICF on relevant aspects of the two studies, with serious health risks. For the sake of increasing transparency and social control, it is proposed the mandatory publication of the ICF in studies supported by public funds, presentation of an objective summary of the study at the beginning of the ICF, publication of central elements of the protocol of clinical trials in open access Brazilian virtual platforms, and promulgation of a dedicated law to improve scientific and ethical integrity in Brazilian medical research.

El Sistema CEP/CONEP es responsable del análisis ético de la investigación en Brasil, sometida al control social, con la misión de proteger a los participantes en la investigación.  El Formulario de Consentimiento Libre e Informado es el documento público que implementa la protección de los participantes. El artículo presenta dos casos de investigación médica en la región amazónica sobre malaria y tratamiento con cloroquina para COVID-19, en que los participantes no fueron informados, en el documento de consentimiento informado, aprobado por el sistema CEP/CONEP, sobre aspectos relevantes de los estudios, con graves riesgos para la salud.  Para aumentar la transparencia y el control social, el artículo propone la divulgación obligatoria del modelo de consentimiento informado en estudios financiados con recursos públicos, la presentación de un resumen objetivo del estudio al inicio del documento de consentimiento, la publicación de elementos centrales del protocolo de ensayos clínicos en plataformas virtuales brasileñas de acceso abierto, y la promulgación de una ley para perfeccionar la integridad científica y ética en la investigación médica brasileña.

O Sistema CEP/CONEP é responsável pela regulação ética de pesquisas no Brasil, comprometido com o controle social, para proteger os direitos dos participantes em pesquisas.

O artigo aborda dois casos de pesquisas médicas na região amazônica, sobre malária e tratamento com cloroquina para COVID-19, em que os participantes foram desinformados no TCLE, aprovado pelo sistema CEP/CONEP, sobre aspectos relevantes dos estudos, com sérios riscos à saúde.  Para ampliar a transparência e  controle social, propõe-se a divulgação obrigatória do modelo de TCLE em pesquisas que usem recursos públicos, apresentação de resumo itemizado no início do TCLE, publicação de elementos centrais do protocolo de ensaios clínicos em plataformas virtuais brasileiras de acesso aberto e promulgação de lei para aprimorar a inteireza científica e ética nas pesquisas médicas brasileiras.

Actividad científica enfermera y congresos: uso y abuso / Nurses scientific activity and congresses: use and abuse

Objetivo principal: Describir las características de la participación en eventos científicos de las enfermeras y de la producción científica asociada a los mismos. Metodología: estudio exploratorio descriptivo transversal con encuesta ad hoc distribuida online y con muestreo de bola de nieve. Resultados principales: 1033 respuestas válidas. Los perfiles que más participan en congresos son hombres (30,3 % p<0,01) y enfermeras residentes (7,85 % p<0,01). Casi un tercio de las personas que trabajan en la práctica clínica (31,1 %) no asiste a ningún evento ni presenta trabajos y de ellas la mitad (un 14,3% del total), no tiene titulación de postgrado. 16,84 % dice presentar el mismo trabajo en varios eventos y este grupo se correlaciona significativamente tanto con quienes presentan más comunicaciones (p<0,05) como pósteres (p<0,05). Solo un 2,70 % manifiestan presentar un número extraordinario de comunicaciones en eventos (más de 11 en un año) y el 2,22 % de póster. Se trata de personas significativamente más jóvenes (31,8±8,09) con titulación de máster propio u oficial y con menos experiencia profesional. Conclusión principal: Se relacionan claramente las prácticas poco éticas con el incentivo de estar valoradas en las bolsas de empleo y carrera profesional especialmente en las enfermeras más jóvenes.(AU)

Objective: to describe the characteristics of the participation in scientific events of spanish nurses and scientific production associated with them. Method: cross-sectional descriptive study with Ad-Hoc online survey distributed; with snowball sampling. Results: 1033 valid answers. The profiles that participate more in congresses are men (30,3 % p <0.01) and resident nurses (7,85 % p <0,01). Almost a third part of people who work in clinical practice (31,1 %) do not attend at any event, and half of them (14,3 % of the total) do not have a postgraduate degree. 16,84 % say they present the same abstract in several events and this group correlates significantly with those who present more communications (p <0,05) and posters (p <0,05). Only 2,70 % claim to present an extraordinary number of communications in scientifics events (more than 11 in a year). These are significantly younger people (31.8 ± 8.09) with a master's degree and with less professional experience. Only 2,70 % present an extraordinary number of communications and 2,22% poster. Conclusions: The unethical practices are clearly related to the incentive for being valued in the employment and profesional careers, especially in youngest nurses.(AU)

Infracción del deber de cuidado y responsabilidad penal del profesional de la salud

Introducción: A pesar de su antigüedad la cuestión de la responsabilidad jurídico-penal del profesional de la salud adquiere cada vez mayor importancia en el orden teórico y práctico, en cuyo escenario se pone de manifiesto una excesiva judicialización de la actividad médica como mecanismo de tutela de los derechos del paciente. Objetivo: Sistematizar las diferentes posturas teóricas que en la actualidad se aprecian en torno a la judicialización de la actividad médica y las causas que la estimulan. Método: Se llevó a cabo un estudio de carácter documental a través de una revisión bibliográfica exhaustiva en buscadores bibliográficos como Scopus, SciELO, Google Académico y PubMed. La indagación de carácter argumentativa y exploratoria se realizó el 16 de marzo de 2023 y de los 30 artículos encontrados que abordaron la problemática de la mala praxis médica, solo 11 fueron elegidos para el estudio según criterios de selección. Desarrollo: Se sistematizaron las posturas teóricas sobre la judicialización de la actividad médica y las causas que la estimulan; además se determina la correcta interpretación de la lex artis como mecanismo de heterointegración normativa del deber de cuidado del ejecutor de actos médicos, en aras de evitar excesos en la aplicación de la ley penal en este ámbito de actuación profesional. Consideraciones finales: Una mayor intervención del Derecho Penal en el ejercicio de la Medicina no es el paradigma político criminal más eficiente en aras de proteger la vida e integridad del paciente frente a hechos de mala praxis médica.

Introduction: Legal and criminal liability of the health professionals, regardless its antiquity, at present has becoming more and more theoretical and practical relevance in which an excessive judicialization of medical activity is revealed as a mechanism for the protection of patient rights. Objective: Systematization of the different theoretical positions that are currently identified around the judicialization process of medical activity and the likely causes that stimulate it. Method: A documentary study was carried out through an exhaustive bibliographic review in bibliographic search engines such as Scopus, SciELO, Google Scholar and PubMed. The argumentative and exploratory research was conducted on March 16, 2023 and of the 30 articles found concerning medical malpractice, only 11 were chosen for the study with strict selection criteria. Development: The theoretical positions on the judicialization of medical activity and the causes that stimulate it were systematized; in addition, the correct interpretation of the lex artis was presented as a mechanism of normative heterointegration of the duty of care by the medical personnel, in order to avoid excesses in the application of the criminal law in this area of professional activity. Final considerations: A much greater intervention of criminal law in the practice of medicine is not the most efficient policy to protect the life and integrity of the patient in the face up to the medical malpractice.
