RESUMO

OBJECTIVES: Despite cervical cancer (CC) being a preventable disease, its incidence remains high in marginalized communities due to inequalities that restrict access to health services. This article investigates the experiences, perceptions, and attitudes regarding the screening of indigenous women in a region of the Colombian Amazon during a cervical cancer prevention initiative facilitated by community participation. DESIGN: Qualitative study based on interviews conducted with women and indigenous leaders from Paujil reserve. They participated in research focused on cervical cancer prevention, which employed a methodology of collaboration between academia and communities aimed at enhancing women's health and reducing inequalities in access to healthcare services. The analysis utilized a deductive and inductive approach. RESULTS: Five main themes were addressed: 'Barriers within health services'; 'Individual and cultural constraints'; 'Motivations and facilitators'; 'Positive experiences within the research framework'; and 'Suggestions for encouraging women's participation.' Challenges related to appointment scheduling and result delivery were frequently cited as obstacles to access. Misinformation, feelings of shame, fear, and distrust towards health services played significant roles in the reluctance to undergo screening. Factors such as support from family and community networks, respectful treatment, ease of scheduling appointments, the presence of female healthcare professionals, and involvement of leaders fluent in indigenous languages were identified as positive facilitators of screening acceptance. CONCLUSION: Understanding the factors that influence access to screening is crucial for reducing inequalities in service delivery for indigenous women. The involvement of trained leaders who can identify these factors and motivate women can have a positive impact on the acceptance and guidance of cervical cancer prevention programs.

RESUMO

Random mutagenesis, such as error-prone PCR (epPCR), is a technique capable of generating a wide variety of a single gene. However, epPCR can produce a large number of mutated gene variants, posing a challenge in ligating these mutated PCR products into plasmid vectors. Typically, the primers for mutagenic PCRs incorporate artificial restriction enzyme sites compatible with chosen plasmids. Products are cleaved and ligated to linearized plasmids, then recircularized by DNA ligase. However, this cut-and-paste method known as ligation-dependent process cloning (LDCP), has limited efficiency, as the loss of potential mutants is inevitable leading to a significant reduction in the library's breadth. An alternative to LDCP is the circular polymerase extension cloning (CPEC) method. This technique involves a reaction where a high-fidelity DNA polymerase extends the overlapping regions between the insert and vector, forming a circular molecule. In this study, our objective was to compare the traditional cut-and-paste enzymatic method with CPEC in producing a variant library from the gene encoding the red fluorescent protein (DsRed2) obtained by epPCR. Our findings suggest that CPEC can accelerate the cloning process in gene library generation, enabling the acquisition of a greater number of gene variants compared to methods reliant on restriction enzymes.

RESUMO

BACKGROUND: Continuous glucose monitoring can improve glycemic control for hospitalized patients with diabetes, according to current evidence. However, there is a lack of consensus-established recommendations for the management of hospitalized patients with diabetes using flash continuous glucose monitoring system (fCGM) in Latin America. Therefore, this expert consensus exercise aimed to establish guidelines on the implementation of fCGM in the management of hospitalized patients with diabetes in Latin America. METHODS: The modified Delphi method was applied on a panel of nine specialists, establishing consensus at 80%. A twenty-two-question instrument was developed to establish recommendations on the use of fCGM in hospitalized patients living with diabetes. RESULTS: Based on consensus, experts recommend the use of fCGM in hospitalized patients with diabetes starting at admission or whenever hyperglycemia (> 180 mg/dl) is confirmed and continue monitoring throughout the entire hospital stay. The recommended frequency of fCGM scans varies depending on the patient's age and diabetes type: ten scans per day for pediatric patients with type 1 and 2 diabetes, adult patients with type 1 diabetes and pregnant patients, and seven scans for adult patients with type 2 diabetes. Different hospital services can benefit from fCGM, including the emergency room, internal medicine departments, intensive care units, surgery rooms, and surgery wards. CONCLUSIONS: The use of fCGM is recommended for patients with diabetes starting at the time of admission in hospitals in Latin America, whenever the necessary resources (devices, education, personnel) are available.

RESUMO

In intensive swine production systems,, the practice of regrouping unfamiliar pigs is common, often leading to aggressive behavior. Although the effect of different musical genres composed for humans has been evaluated in pigs to mitigate aggression, there have been few attempts to create music specifically for pigs. Here, we assess whether sensory stimulation through music, created by adapting the acoustic parameters in the sound mix, induces changes in the aggressive behaviors of pigs during regrouping. Six litters of 10-week-old piglets were randomly selected and assigned to different treatments. The control group (Group A) received no intervention, while Group B was exposed to music for two continuous hours in the morning and afternoon from the time of regrouping. Group C received musical stimulation for one continuous hour in the morning following regrouping. A significant reduction in the frequency and duration of aggressive behaviors was observed in the groups that received musical stimulation during regrouping. Additionally, social, and individual play behaviors showed a decrease in the musical stimulation groups. These findings provide evidence for the effectiveness of created music as a strategy in reducing aggressive behavior during pig regrouping, which can enhance the welfare of pigs and offer a practical solution for pig producers to minimize aggression and its associated negative impacts.

RESUMO

The marine environment is a rich reservoir of diverse biological entities, many of which possess unique properties that are of immense value to biotechnological applications. One such example is the red fluorescent protein derived from the coral Discosoma sp. This protein, encoded by the DsRed gene, has been the subject of extensive research due to its potential applications in various fields. In the study, a variant of the red fluorescent protein was generated through random mutagenesis using the DsRed2 gene as a template. The process employed error-prone PCR (epPCR) to introduce random mutations, leading to the isolation of twelve gene variants. Among these, one variant stood out due to its unique spectral properties, exhibiting dual fluorescence emission at both 480 nm (green) and 550 nm (red). This novel variant was expressed in both Escherichia coli and zebrafish (Danio rerio) muscle, confirming the dual fluorescence emission in both model systems. One of the immediate applications of this novel protein variant is in ornamental aquaculture. The dual fluorescence can serve as a unique marker or trait, enhancing the aesthetic appeal of aquatic species in ornamental settings.

RESUMO

Morris water maze (MWM) test is widely used to evaluate the learning and memory deficits in rodents. Image processing and pattern recognition can be used to analyse videos and recognize automatically the tracking in MWM. There are several commercial and free access software that allows analyzing the behavioral tasks although they also have limitations such as automation, cost, user intervention among other things. The aim of this paper was to develop a new image processing technique to automatically analyse the track of the rat in the MWM, which we called RatsTrack. The MWM test was performed with an animal model for Alzheimer, and the videos were recorded to measure the distance, time, and speed. The segmentation method based on the projection of the video frames was made for pool identification, eliminating the rat, while conserving the shape of the pool. Then, the Hough transformation was used to recognize the position and radius of the pool. Finally, the frame in which the rat is released into the pool was established automatically using mathematical morphology techniques and added as a plugin on free access ImageJ software. The new image processing technique, RatsTrack, successfully detected and located the pool and rat without user intervention, significantly decreasing operational time and providing results for distance, time, speed, and acceleration parameters of the MWM test. Alzheimer's rats compared with the control group presented significant data measured with the RatsTrack. RatsTrack is a plugin of ImageJ software and will be made freely available for public use.

RESUMO

OBJECTIVE: HbA1C is the "gold standard" parameter to evaluate glycemic control in diabetes; however, its correlation with mean glucose is not always perfect. The objective of this study was to correlate continuous glucose monitoring (CGM)-derived hemoglobin glycation index (HGI) with microvascular complications. METHODS: We conducted a cross-sectional study including permanent users of CGM with type 1 diabetes mellitus or latent autoimmune diabetes of the adult. HGI was estimated, and presence of microvascular complications was compared in subgroups with high or low HGI. A logistic regression analysis to assess the contribution of high HGI to chronic kidney disease (CKD) was performed. RESULTS: In total, 52 participants who were aged 39.7 ± 14.7 years, with 73.1% women and 15.5 years (IQR, 7.5-29 years) since diagnosis, were included; 32.7% recorded diabetic retinopathy, 25% CKD, and 19.2% neuropathy. The median HbA1C was 7.6% (60 mmol/mol) and glucose management indicator (GMI) 7.0% (53 mmol/mol). The average HGI was 0.55% ± 0.66%. The measured HbA1C was higher in the group with high HGI (8.1% [65 mmol/mol] vs 6.9% [52 mmol/mol]; P < .001), whereas GMI (7.0% [53 mmol/mol] vs 7.0% [53 mmol/mol]; P = .495) and mean glucose were similar in both groups (153 mg/dL vs 153 mg/dL; P = .564). In the high HGI group, higher occurrence of CKD (P = .016) and neuropathy were observed (P = .025). High HGI was associated with increased risk of CKD (odds ratio [OR]: 5.05; 95% CI: 1.02-24.8; P = .04) after adjusting for time since diagnosis (OR: 1.09; 95% CI: 1.02-1.16; P = .008). CONCLUSION: High HGI measured by CGM may be a useful marker for increased risk of microvascular diabetic complications.

RESUMO

Alopecia areata (AA) represents an underrecognized burden in Latin America (LA), severely impacting quality of life (QoL). This impact is exacerbated by limited access to specialized dermatologic care and therapies for AA within and among nations. Many of the unmet needs for AA globally also exist in LA. The region has geographic, ethnic, cultural, and economic conditions. With new AA medicines targeting immunologic pathways on the horizon, LA must prepare regarding regulatory issues, reimbursement, awareness, and education to give adequate and timely treatment for patients with AA. To address these issues, the Americas Health Foundation convened a panel of six dermatologists from Argentina, Brazil, Colombia, and Mexico who are experts in AA and its comorbidities for a 3-day virtual meeting to discuss AA diagnosis and treatment in LA and create a manuscript offering recommendations to address discussed barriers. This publication examines unmet AA needs in LA, treatment, and innovative therapies and recommends improving AA care. Access constraints to conventional and novel medicines hinder appropriate treatments for patients. Therapy initiation delays can affect QoL, mental health, and disease progression. People with AA face stigmas, discrimination, and misconceptions owing to a lack of disease awareness. With promising new treatments for AA on the horizon, all stakeholders must coordinate efforts to enhance LA's AA management landscape and improve patient outcomes.

RESUMO

BACKGROUND: Adolescents and young adults are vulnerable to developing mental distress. However, evidence suggests that more than half of the young people with symptoms of depression and anxiety overcome their distress within a year. However, there is little research on the exact resources that young people use and help them to recover. The aim of this study was to explore how arts activities can support the recovery of young people engaged with arts organizations in Bogota. METHODS: We recruited 38 participants from two arts organizations in Bogotá and conducted six focus groups embedded within artistic workshops. The type of activities in the workshops varied reflecting the different teaching methods of the two organizations. The focus group discussions were recorded and analyzed using thematic analysis. RESULTS: Five themes explained how arts activities can help young people participating in artistic organizations to overcome mental distress: i) allowing the expression of emotions; ii) helping to manage and transform emotions; iii) distracting from problems; iv) facilitating social support and relationships; and v) contributing to the identity of young people. CONCLUSIONS: For young people who participate in artistic organizations, the arts are a resource for overcoming negative emotions such as anxiety, depression, and sadness. The beneficial role of arts activities includes different process of managing, expressing, and distracting from distress, and it differs depending on whether arts are perceived as a professional vocation or a hobby.

RESUMO

Resumen: Toda muerte bajo custodia es potencialmente ilícita por acción u omisión del Estado. Se presenta el reporte sistematizado desde la perspectiva forense de la muerte bajo custodia en la prisión política en Uruguay durante el terrorismo de Estado. Objetivos: a) conocer la magnitud del fenómeno; b) caracterizar a las víctimas; c) determinar causas, maneras y circunstancias de las muertes en los casos que aún no habían sido estudiados; d) sistematizar las causas, maneras y circunstancias de muerte en toda la población estudiada. Material y métodos: se empleó la nómina oficial de víctimas del período de terrorismo de Estado y se estudió la información pública y/o accesible para investigaciones académicas. Las muertes no estudiadas previamente fueron analizadas por una Junta Médica que dictaminó en base a la metodología de la autopsia histórica. Resultados: entre 27/06/1973 y 28/02/1985 murieron bajo custodia en Uruguay por motivos políticos 108 personas; 36 (33%) en un centro de detención clandestino o irregular, 34 (31%) en un establecimiento de detención regular, 19 (18%) continúan como detenidos desaparecidos y 19 (18%) murieron durante operativos de detención o represión. El 81% fueron hombres y la edad media fue 37 años. El 67% eran obreros o empleados y el 23% estudiantes. El 69% fueron muertes violentas y la tortura fue la causa principal de muerte. En nueve de las 32 muertes naturales se demostraron negligencias o fallas asistenciales con ostensible incidencia en el resultado letal. Conclusiones: los resultados obtenidos confirman plenamente el principio general de que se trata de muertes potencialmente ilícitas y la consecuente necesidad de una investigación exhaustiva.

Summary: All deaths in police custody are potentially illicit on account of the government's acts of commission or acts of omission. The study presents a systematized report from the forensic perspective, of deaths in police custody of political prisoners in Uruguay during the period of state terrorism. Objectives: a) to learn about the scale of the phenomenon; b) to characterize victims; c) to determine the causes, ways and circumstances of deaths in the cases that had not been studied yet; d) to systematize the causes, modes and circumstances of death in all the studied population. Method: the study used the official list of victims for the period of State terrorism and analyzed both public information and information that was available for academic research. The deaths that had not been previously studied were reviewed by a Medical Board that rendered a decision through a historic autopsy. Results: in Uruguay, 108 people died for political reasons in police custody from June 27, 1973 to February 28, 1985; 36 (33%) victims died in a clandestine or irregular detention center, 34 (31%) in a regular prison; 19 (18%) are still missing and 19 (18%) died during detention or repression operations. 81% of victims were male and average age was 37 years old. 67% were workers or employees and 23% were students. 69% accounted for violent deaths and torture was the main cause. Negligence and failures in care were seen in 9 out of the 32 natural deaths, what evidently impacts the lethal outcome. Conclusions: the results obtained fully confirm the general principle that these are potentially illicit.

RESUMO

RESUMEN INTRODUCCIÓN: El desarrollo de anticuerpos monoclonales (mAbs) contra el péptido relacionado con el gen de la calcitonina (CGRP) ha determinado una nueva era terapéutica en la profilaxis de migraña, demostrando su efectividad en pacientes con migraña episódica (ME) y migraña crónica (MC), con respuesta desde pacientes naïve hasta refractarios a múltiples medicamentos. La disminución del 50% de los ataques de migraña al mes (DMM) durante los primeros 3 meses de uso es el desenlace aproximado en el 50% de los pacientes que reciben esta terapia. OBJETIVO: Este consenso de la Asociación Colombiana de Neurología (ACN) tiene el objetivo de guiar la selección y uso racional de los mAbs antiCGRP en pacientes con ME y MC. MATERIALES Y MÉTODOS: El comité de cefalea de la ACN mediante la aplicación de la metodología Delphi y discusiones en reuniones posteriores desarrolló un documento en formato de consenso soportado en literatura y recomendaciones de expertos. RESULTADOS: Se obtuvieron respuestas de 14 expertos en cefalea sobre moléculas utilizadas en profilaxis de migraña, analizando su aplicabilidad en situaciones clínicas frecuentes. DISCUSIÓN: Los mAbs antiCGRP han demostrado efectividad con adecuado soporte fisiopatológico, considerando que son moléculas de alto precio en una enfermedad de alta prevalencia, existe la necesidad de guíar la selección del paciente que mejor puede beneficiarse de su administración CONCLUSIONES: Los mAbs antiCGRP están recomendados en pacientes con ME y MC que presentan falla terapéutica a otras moléculas profilácticas.

ABSTRACT INTRODUCTION: The development of monoclonal antibodies (mAbs) against Calcitonin Gene Related Peptide (CGRP) has determined a new therapeutic era in migraine prophylaxis, demonstrating its effectiveness in patients with episodic migraine (EM) and chronic migraine (CM), obtaining a response in naive patients and in those who are refractory to multiple medications. A 50% decrease in migraine attacks per month during the first 3 months of use is the approximate outcome in 50% of patients receiving this therapy. OBJECTIVE: This consensus from the Colombian Association of Neurology (ACN) has the objective of serving as a guide for the rational use of antiCGRP mAbs in patients with EM and CM. METHODS AND MATERIALS: The headache committee through the application of the Delphi methodology and discussions in subsequent meetings, develops this consensus, supported in the published literature and expert recommendations. RESULTS: Fourteen answers from headache experts were received regarding the use of drugs for migraine prophylaxis, analyzing their applicability in frequent clinical situations. DISCUSSION: AntiCGRP mAbs have proved their effectiveness with adequate pathophysiological support, but with a high price in a highly prevalent disease, there is then a need to select the patient who best benefits from this therapy. CONCLUSIONS: AntiCGRP mAbs are recommended in patients with EM and CM that have previously failed to other prophylactic drugs.

RESUMO

BACKGROUND: Atopic dermatitis (AD) is considered as one of the most frequent chronic skin conditions. Previous AD epidemiologic studies have been mainly retrospective and/or have been performed through surveys instead of in-person visits. Epidemiological studies concerning AD in Latin American countries are scarce. OBJECTIVE: To describe sociodemographic and clinical features and the economic burden of AD on children and adult patients in Colombia through in-person visits. METHODS: This was a cross-sectional study of 212 patients that included sociodemographic and clinimetric data. The diagnostic criteria of Hanifin and Rajka was used and data relating to disease distribution, disease severity (through the BSA: Body surface area; EASI: Eczema Area and Severity Index; SCORAD: Scoring Atopic Dermatitis), Fitzpatrick's skin phototypes, personal and familiar history of allergic diseases, previous treatments, and personal history of comorbidities, was collected. RESULTS: Patient age range was 12-76, and 52.8% were female. Disease distribution was mainly flexural (19.6%). Early age start, Denni-Morgan fold, and infections tendency were more frequent in adolescents compared to adults. Mean age of diagnosis was 12 years old, AD diagnosis was made mostly by a dermatologist, 48.1% (102 patients) reported alcohol consumption, and 59% of consumers were heavy drinkers. Comorbidities found were: chronic rhinitis (68.9%) food allergy (32.5%), allergic conjunctivitis (29.7%), and asthma (28.8%). Around 81% earned less than $896 US dollars and 59% invested 6-30% of their monthly budget yearly, and 40% had work or school absenteeism. Mean scores of BSA, EASI, and SCORAD involvement were 32.6, 13.7, and 42.4, respectively. CONCLUSIONS: This study adds well-supported data through an in-depth clinical and economical characterization of Colombian adolescents and adult patients with atopic dermatitis and shows its high impact and burden on patients and their families. It also contributes to understand the burden of AD in Latin America.

RESUMO

AIMS: Type 1 diabetes (T1D) is a growing chronic disease. Evidence of whether the healthcare setting affects management and glycemic control is scarce. We evaluate outcomes in patients with T1D in private and public healthcare settings in Mexico, registered in the National T1D Registry in Mexico (RENACED-DT1). METHODS: Biochemical parameters, diabetes education, and treatment were analyzed considering the data registered in the last visit. Development of chronic complications was determined during follow-up. RESULTS: We included 1,603 patients; 71.5% (n = 1,146) registered in the public system, and 28.5% (n = 457) in a private institution. Patients in the public setting had higher HbA1c (8.6%, IQR: 7.3%-10.5% vs 7.7%, IQR: 7.0%-8.8%; p < 0.001). Indicators of diabetes education, glucose monitoring, and use of insulin-pumps were lower in the public setting. Patients in the public setting were at higher risk of diabetic chronic kidney disease, retinopathy, and neuropathy. Diabetes knowledge was a mediator between type of healthcare setting and the likelihood of achieving glycemic control. CONCLUSIONS: Patients registered in public healthcare settings have an adverse metabolic profile and higher risk of complications. Social factors need to be addressed in order to implement multidisciplinary measures focused on diabetes education for patients with T1D in Mexico.

RESUMO

Given that the COVID-19 era has changed the behavior of all individuals, and since previous reports about its possible impact on atopic dermatitis (AD) patients remained speculative, in this survey we aimed to explore the real impact of COVID-19 among AD patients. All participants provided verbal consent prior to completing the survey. A 37-question web-based survey with no personal identifiers was sent to 212 previously identified AD patients. Itching, sleep disturbances, SARS-CoV-2, illness cost, economic dependence, monthly income, and monthly investment in AD before and during the pandemic, were all included in the analysis. A response rate of 73.1% was obtained. The mean age of participants was 30 years-old, and 57% were women. Around 75% reported AD worsening, and 59.4% of the patients reported sleep problems. Uncertainty, anxiety, and pessimism were frequent during the pandemic. Only 1.3% tested positive for SARS-CoV-2, and it was only significantly associated with comorbidities (p=0.03; Chi2 Test). A significant difference was found in economic dependence and monthly income when compared between before and during the pandemic. This study provides probably the best possible assessment of the clinical, social, and economic effects of the pandemic on patients with an already proven diagnosis of AD.

RESUMO

Background: Information regarding diagnosis, treatment, and follow-up of patients with type 1 diabetes (PWT1D) in Mexico is limited. We developed an on-line platform Registro Nacional de Pacientes con Diabetes Tipo 1 (RENACED-DT1). Objective: The objective of the study was to describe the characteristics and healthcare of PWT1D registered in RENACED-DT1. Methods: Analyses of 965 PWT1D from July 2014 to January 2018 in different endocrinology clinics around Mexico. Results: Sixty-one percent were female with median age of 21 years, age at diagnosis 11 years, and disease duration at inclusion 8.2 years. Treatment regimen was basal-bolus in 61% and insulin-pumps in 21% (mainly in the private sector); 33.3% with self-monitoring of blood-glucose (SMBG) ≥4 times/day. Mean HbA1c at last follow-up was 8.7 ± 2.1% (72±23 mmol/mol), 18% had HbA1c < 7% (53 mmol/mol), and 35% > 9% (75 mmol/mol). SMBG ≥ 4 times/day was associated with HbA1c < 7%. Time since diagnosis > 10 years, female sex, BMI ≥ 30 kg/m2, SMBG < 4 times/day, and any hypoglycemia were associated with microvascular complications (p < 0.05). Conclusions: Percentage of patients achieving HbA1c < 7% is low; increased blood glucose monitoring is associated with better glycemic control. The achievement of optimal glycemic control must be increased to reduce the incidence of chronic complications and improve quality of life in PWT1D.

RESUMO

BACKGROUND: The sequencing of alleles of the HLA-B, a human leukocyte antigen (HLA) class I gene, was established as the most polymorphic of chromosome 6 and of the entire human genome. In this locus, the HLA-B*27 allele is highly polymorphic and has clinical relevance. Literature about the subtypes and singular frequency of these alleles in Colombia's healthy population is scarce. OBJECTIVE: The aim of this study was to establish the HLA-B allele, genotype, and haplotype frequencies in a healthy Colombian population and analyze their association with the sex and geographical distribution of the individuals studied. METHODS: This is a nonexperimental and descriptive study. The data from whole-blood samples whose HLA genes were genotyped by protocol with the Luminex 100/200 xMAP technology were evaluated. HLA-B*27 positivity was confirmed by the new-generation sequencing technology. The associations between the HLA-B alleles and demographic variables were evaluated by χ2 and Fisher exact tests. RESULTS: Twenty-seven HLA-B genotypes were identified in 255 individuals, with the highest frequencies for HLA-B*35 (44.7%), B*40 (19.6%), and B*44 (16.8%). Additionally, 89 HLA-B alleles were found; the most common were HLA-B*35:01 (6.7%) and B*40:02 (6.5%). Nine individuals tested positive for the HLA-B*27 allele with genotype and allele frequencies of 3.5% and 1.8%, respectively; the HLA-B*27:05:02 subtype predominated. CONCLUSIONS: Here, we report the most common HLA-B allele, genotype, and haplotype frequencies in a healthy Colombian population group and analyzed their association with the sex and geographical distribution of the individuals studied. Results for the HLA-B*27 allele confirm racial mixing in Colombia with a high degree of Caucasian influence, as well as the repopulation of Colombia's central region, attributed to the migration phenomena. Results agree with data published in Colombia that was obtained from cord blood samples.

RESUMO

The dewaxed dichloromethane extract of Urolepis hecatantha and the compounds isolated from it were tested for their in vitro activity on Trypanosoma cruzi epimastigotes and Leishmania infantum promastigotes. The extract of U. hecatantha showed activity against both parasites with IC50 values of 7 µg/mL and 31 µg/mL, respectively. Fractionation of the dichloromethane extract led to the isolation of euparin, jaceidin, santhemoidin C, and eucannabinolide. The sesquiterpene lactones eucannabinolide and santhemoidin C were active on T. cruzi with IC50 values of 10 ± 2 µM (4.2 µg/mL) and 18 ± 3 µM (7.6 µg/mL), respectively. Euparin and santhemoidin C were the most active on L. infantum with IC50 values of 18 ± 4 µM (3.9 µg/mL) and 19 ± 4 µM (8.0 µg/mL), respectively. Eucannabinolide has also shown drug-like pharmacokinetic and toxicity properties.

RESUMO

RESUMEN El manejo del paciente con estado migrañoso en urgencias incluye un arsenal terapéutico multimodal en búsqueda de la mejoría del dolor y la reducción de la recurrencia. La mayoría de los pacientes responde al manejo inicial, pero en casos no despreciables este resultado no se obtiene con las medicaciones de primera línea y es necesario el uso de otros medicamentos y opciones terapéuticas que incluyen: bloqueos pericraneales, lidocaína, levetiracetam, propofol y, en casos seleccionados, el uso de opiodes. En este escrito se presenta un caso clínico de migraña que no mejora con el manejo inicial en urgencias y requiere el uso de otras opciones.

SUMMARY Management of the patient with status migrainosus in the emergency department includes a multimodal therapeutic arsenal seeking to improve pain and to reduce recurrence; the majority of patients respond to enhanced initial management, but in non-negligible cases this result is not obtained with first-line medications and the use of other medications and therapeutic options is necessary, including: pericranial blocks, lidocaine, levetiracetam, propofol and in selected cases the use of opioids. In this review we present a clinical case of migraine that does not improve in the initial management in the emergency department and requires the use of other options for management.
