ABSTRACT

The use of substances with addictive potential is a relevant health problem. Scientific evidence suggests that the underlying mechanisms that regulate behavioral processes in addictions involve a complex interplay between genetic and environmental factors. Therefore, this narrative review aims to provide a framework to synthesize the evidence on gene-environment-agent interactions from the perspective of the natural history of the disease and the stages of the addictive process for alcohol, nicotine, cannabis, psychostimulants, and opioids. In this review, we conducted an exhaustive literature search without time limits in PubMed, Ebsco, Lilacs, and SciELO, reviewing the title and abstract we selected original articles in humans or animals that addressed the etiology of addictions according to the methodological approach of gene-environment (G-E) interaction, including articles in Spanish, English, and Portuguese. Genetic studies have revealed the critical role of epigenetic modifiers (histone acetylation) in maintaining brain homeostasis in pathological conditions and focusing on G-E interactions will also allow characterizing subgroups (based on environmental factors) at high risk for addictive behaviors that can be targeted for specific interventions, Thus, treatment strategies should encompass a combination of psychosocial interventions with gene therapy involving pharmacological manipulations of histones that may contribute to design better therapies and perhaps lead to more successful management of drug dependencies.


El consumo de sustancias con potencial adictivo es un problema relevante de salud. La evidencia científica sugiere que los mecanismos subyacentes que regulan los procesos comportamentales en las adicciones involucran un complejo interjuego entre factores genéticos y ambientales. Por lo tanto, esta revisión narrativa tiene como objetivo aportar un marco de referencia que permita sintetizar la evidencia sobre interacciones genes- ambiente-agente desde la perspectiva de la historia natural de la enfermedad y los estadios del proceso adictivo para: alcohol, nicotina, cannabis, psicoestimulantes y opioides. En esta revisión realizamos una búsqueda exhaustiva de la literatura sin límites de tiempo en PubMed, Ebsco, Lilacs y SciELO, revisando el título y el resumen se seleccionaron artículos originales en humanos o animales que abordaran la etiología de las adiciones según el enfoque metodológico de interacción entre genes y ambiente (G-A), incluyendo artículos en español, inglés y portugués. Los estudios genéticos han revelado el papel crítico de los modificadores epigenéticos (acetilación de las histonas) en mantener la homeóstasis cerebral en condiciones patológicas y enfocarse en las interacciones G-A también permitirá caracterizar subgrupos (basados en los factoresambientales) de alto riesgo para conductas adictivas que pueden ser objeto de intervenciones específicas, por lo que, las estrategias de tratamiento deben englobar una combinación de intervenciones psicosociales con terapia génica que involucren las manipulaciones farmacológicas de las histonas que pueden contribuir a diseñar mejores terapias y tal vez conducir a un manejo más exitoso de las drogodependencias.


O consumo de substâncias com potencial viciante é um relevante problema de saúde. Evidências científicas sugerem que os mecanismos subjacentes que regulam os processos comportamentais em vícios envolvem uma interação complexa entre fatores genéticos e ambientais. Portanto, esta revisão narrativa visa fornecer um quadro de referência que permita sintetizar as evidências sobre interações gene-ambiente-agente sob a perspectiva da história natural da doença e as etapas do processo de dependência para: álcool, nicotina, cannabis, psicoestimulantes e opióides. Nesta revisão, realizamos uma busca exaustiva da literatura sem limites de tempo no PubMed, Ebsco , Lilacs e SciELO, revisando o título e o resumo, foram selecionados artigos originais em humanos ou animais que abordassem a etiologia dos acréscimos de acordo com a abordagem metodológica de interação entre genes e ambiente (GA), incluindo artigos em espanhol, inglês e português. Estudos genéticos revelaram o papel crítico dos modificadores epigenéticos (acetilação de histonas) na manutenção da homeostase cerebral em condições patológicas, e o direcionamento das interações GA também permitirá caracterizar subgrupos (com base em fatores ambientais) de alto risco para comportamentos aditivos que podem ser alvo de ataques específicos. intervenções, portanto, as estratégias de tratamento devem abranger uma combinação de intervenções psicossociais com terapia gênica envolvendo manipulações farmacológicas de histonas que podem contribuir para projetar melhores terapias e talvez levar a um manejo mais bem-sucedido das dependências de drogas.

ABSTRACT

Introducción: Se describe la evolución de un paciente que recibe morfina intratecal mediante una bomba de infusión, que le fuera implantada hace 14 años para tratamiento de su dolor lumbar crónico post-laminectomía. Material y método: Requería la administración de 60 mg/día de morfina subcutánea que le provocaban efectos secundarios que no toleraba, y múltiples internaciones para control del dolor. Se le implantó una bomba de infusión continua (Isomed) conectada a un catéter subaracnoideo, que libera 1 ml/día, y requiere ser llenada cada 60 días. Resultados: Se observó una disminución del dolor promedio de 50% al año, y de 75% a los 6 y 14 años. Requirió un aumento progresivo de las dosis de llenado, que pasaron de 30 mg de morfina (0.5 mg/día) al inicio, a 40 mg de morfina (0.66 mg /día) al año, a 70 mg de morfina (1.16 mg/día) a los 6 años, a 140 mg (2.33 mg/día) a los 14 años. No se registraron complicaciones médicas graves. Mantuvo constipación y sudoración durante todo el período, e instaló un hipogonadismo secundario con trastornos de la libido y de la erección que fueron corregidos con la administración de testosterona. No requirió más internaciones por dolor. No se observaron complicaciones relacionadas con el funcionamiento o llenado de la bomba, ni vinculadas al catéter. El paciente manifestó estar satisfecho con el implante. Discusión: A pesar del aumento de las dosis de llenado, expresión del desarrollo de tolerancia, las dosis de morfina/día requeridas son francamente inferiores al límite recomendado. Conclusiones: El balance del riesgo-beneficio del implante resultó positivo, considerando el mejor control del dolor logrado, las menores dosis de morfina utilizadas, así como la ausencia de complicaciones graves y de internaciones para control del dolor.


Introduction: The evolution of a patient receiving intrathecal morphine through an infusion pump that was implanted 14 years ago for the treatment of chronic post-laminectomy low back pain is described. Material and method: It required the administration of 60 mg / day of subcutaneous morphine that caused side effects that did not tolerate, and multiple hospitalizations for pain control. He was implanted with a continuous infusion pump (Isomed) connected to a subarachnoid catheter, which releases 1 ml / day, and needs to be filled every 60 days. Results: An average pain decrease of 50% per year, and 75% at 6 and 12 years was observed. It required a progressive increase in filling doses, which went from 30 mg of morphine (0.5 mg / day) at the beginning, to 40 mg of morphine (0.66 mg / day at the first year, to 70 mg of morphine (1.16 mg / day) at the sixth year, at 140 mg (2.33 mg / day) at the fourteen year. No serious medical complications were recorded, he maintained constipation and sweating throughout the period, and installed secondary hypogonadism with libido and erection disorders, that were corrected with the administration of testosterone. No further hospitalizations were required due to pain. No complications were observed related to the operation or filling of the pump or linked to the catheter. The patient stated that he was satisfied with the implant. Discussion: Despite the increase in filling doses, expression of tolerance development, the required morphine / day doses are frankly below the recommended limit. Conclusions: The risk-benefit balance of the implant was positive, considering the best pain control, the lowest doses used, the absence of serious complications, and the lack of hospitalizations for pain control.


Introdução: Descreve-se a evolução de um paciente que recebeu morfina intratecal através de uma bomba de infusão, implantada há 14 anos para o tratamento de lombalgia crônica pós-laminectomia. Material e método: Necessitou de administração de 60 mg/dia de morfina por via subcutânea, que provocou efeitos colaterais intolerantes, e múltiplas internações para controle da dor. Foi implantada uma bomba de infusão contínua (Isomed) conectada a um cateter subaracnóideo, que libera 1 ml/dia, necessitando de reenchimento a cada 60 dias. Resultados: Observou-se redução média da dor de 50% em um ano e 75% em 6 e 14 anos. Foi necessário um aumento progressivo das doses de enchimento, que passaram de 30 mg de morfina (0,5 mg/dia) no início, para 40 mg de morfina (0,66 mg/dia) por ano, para 70 mg de morfina (1,16 mg/dia) dia) aos 6 anos, para 140 mg (2,33 mg/dia) aos 14 anos. Não foram registradas complicações médicas graves. Manteve constipação e sudorese durante todo o período e desenvolveu hipogonadismo secundário com distúrbios de libido e ereção que foram corrigidos com administração de testosterona. Ele não necessitou de mais hospitalizações por dor. Não foram observadas complicações relacionadas à operação ou enchimento da bomba, ou relacionadas ao cateter. O paciente afirmou estar satisfeito com o implante. Discussão: Apesar do aumento das doses de enchimento, expressão do desenvolvimento da tolerância, as doses necessárias de morfina/dia são francamente inferiores ao limite recomendado. Conclusões: A relação risco-benefício do implante foi positiva, considerando o melhor controle da dor alcançado, as menores doses de morfina utilizadas, bem como a ausência de complicações graves e internações para controle da dor.

ABSTRACT

ABSTRACT BACKGROUND: There is still a debate about what constitutes effective and safe postoperative analgesia in hepatectomy surgery. Erector spinae plane (ESP) block may be an important part of multimodal analgesia application in hepatectomy surgery. OBJECTIVES: To compare the effects of ultrasound-guided bilateral erector spinae plane block combined with intravenous (iv) patient-controlled analgesia (iv PCA), in comparison with iv PCA alone, in hepatectomy surgery. DESIGN AND SETTINGS: Randomized prospective single-blinded study in a tertiary university hospital. METHODS: Fifty patients scheduled for elective hepatectomy surgery were included in the study. Patients were randomized into the ESP group or the control group. In the ESP group, bilateral ESP block was performed preoperatively and iv PCA was used. In the control group, only iv PCA was used. Numerical rating scale (NRS) scores at rest and coughing, analgesic requirements and occurrences of nausea and vomiting were recorded. RESULTS: Intraoperative and postoperative opioid consumption, rescue analgesia requirement and resting and dynamic NRS scores were significantly lower in the ESP group (P < 0.05). There was no significant difference between two groups in terms of the presence of dynamic pain after the first postoperative hour. While all patients in the control group had nausea and vomiting, 24% of the patients in the ESP group did not have nausea and vomiting. CONCLUSION: This study showed that ESP block can be used as a part of multimodal analgesia, with the benefit of reducing opioid consumption and postoperative nausea and vomiting in hepatectomy surgery. CLINICAL TRIAL REGISTRATION: ACTRN12620000466943.

ABSTRACT

Abstract Objective To summarize the available evidence of TAP Block in efficacy in laparoscopic or robotic hysterectomy. Data Sources We searched databases and gray literature for randomized controlled trials in which transversus abdominis plane (TAP) block was compared with placebo or with no treatment in patients who underwent laparoscopic or robot-assisted hysterectomy. Method of Study Selection Two researchers independently evaluated the eligibility of the selected articles. Tabulation, Integration, and Results Seven studies were selected, involving 518 patients. Early postoperative pain showed a difference in the mean mean difference (MD): - 1.17 (95% confidence interval [CI]: - 1.87-0.46) in pain scale scores (I2=68%), which was statistically significant in favor of using TAP block, but without clinical relevance; late postoperative pain: DM 0.001 (95%CI: - 0.43-0.44; I2=69%); opioid requirement: DM 0.36 (95%CI: - 0.94-1.68; I2=80%); and incidence of nausea and vomiting with a difference of 95%CI=- 0.11 (- 0.215-0.006) in favor of TAP. Conclusion With moderate strength of evidence, due to the high heterogeneity and imbalance in baseline characteristics among studies, the results indicate that TAP block should not be considered as a clinically relevant analgesic technique to improve postoperative pain in laparoscopic or robotic hysterectomy, despite statistical significance in early postoperative pain scale scores. Clinical Trial Number and Registry: PROSPERO ID - CRD42018103573.


Resumo Objetivo Resumir as evidências disponíveis sobre a eficácia do bloqueio TAP em histerectomia laparoscópica ou robótica. Fontes de Dados Pesquisamos bancos de dados e literatura cinza por ensaios clínicos randomizados nos quais o bloqueio do plano transverso do abdome (TAP na sigla em inglês) foi comparado com placebo ou com nenhum tratamento em pacientes que foram submetidos a histerectomia laparoscópica ou assistida por robô. Métodos de Seleção de Estudos Dois pesquisadores avaliaram independentemente a elegibilidade dos artigos selecionados. Tabulação, Integração e Resultados Sete estudos foram selecionados envolvendo 518 pacientes. A dor pós-operatória precoce apresentou diferença nasmédias (DM) de: -1 17 (intervalo de confiança [IC] de 95%: - 1 87-0 46) nos escores da escala de dor (I2=68%) o que foi estatisticamente significativo a favor do uso do bloqueio TAP mas sem relevância clínica; dor pós-operatória tardia: DM 0001 (IC95%: - 043-044; I2=69%); necessidade de opioides: DM0 36 (95%CI: - 0 94-168; I2=80%); e incidência de náuseas e vômitos com diferença de 95% CI=- 011 (- 0215-0006) a favor do TAP. Conclusão Com moderada força de evidência devido à alta heterogeneidade e ao desequilíbrio nas características basais entre os estudos os resultados indicam que o bloqueio do TAP não deve ser considerado como uma técnica analgésica clinicamente relevante para melhorar a dor pós-operatória em histerectomia laparoscópica ou robótica apesar da significância estatística nas pontuações da escala de dor pósoperatória inicial. Número e Registro do Ensaio Clínico: PROSPERO ID - CRD42018103573.

ABSTRACT

BACKGROUND@#Patients commonly develop postoperative pain after total knee arthroplasty (TKA). Acupuncture-related techniques and low-level laser therapy could be beneficial for pain management for older individuals.@*OBJECTIVE@#To examine the effect of low-level laser acupuncture (LA) in reducing postoperative pain, pain-related interference in daily life, morphine consumption, and morphine-related side effects in older patients with knee osteoarthritis who underwent TKA.@*DESIGN, SETTING, PARTICIPANTS AND INTERVENTION@#A single-blind randomized placebo-controlled trial was conducted. Patients (N = 82) were recruited and randomly assigned via a computer-generated list to the LA group or a placebo group. The LA group received low-level laser therapy at Sanyinjiao (SP6), Taixi (KI3), Kunlun (BL60), Fengshi (GB31), Futu (ST32) and Neiguan (PC6) after TKA, while the placebo acupuncture group received the same treatment procedure without laser energy output.@*MAIN OUTCOME MEASURES@#The primary outcome was postoperative pain intensity, and it was measured at baseline and hours 2, 6, 10, 24, 48 and 72 after TKA. The secondary outcomes, including relative pain, postoperative pain-related interference in daily life and morphine consumption, were measured at hours 24, 48 and 72 after TKA.@*RESULTS@#Generalized estimating equations revealed significant between-group differences in pain intensity (P = 0.01), and trend differences in pain intensity for the LA group starting at hours 10 to 72 (P < 0.05) and morphine consumption at hours 48 and 72 (P < 0.05). The changes in pain-related interference in daily life were significant (P < 0.05) at 72 h, with the exception of the parameters for worst pain, mood, and sleep. Nausea and vomiting side effects from morphine had significant between-group differences at hours 10 and 24 (P < 0.05).@*CONCLUSION@#Low-level LA gradually reduced older patients' postoperative pain intensity and morphine consumption within the first 72 h after their TKA for osteoarthritis. Low-level LA may have benefits as an adjuvant pain management technique for clinical care.@*TRIAL REGISTRATION@#ClinicalTrials.gov registration number NCT03995446.

ABSTRACT

Background: The coronavirus disease 2019 (COVID-19) has highlighted the scope of heroin dependence and need for evidence-based treatment amongst marginalised people in South Africa. Acute opioid withdrawal management without maintenance therapy carries risks of increased morbidity and mortality. Due to the high costs of methadone, Tshwane's Community Oriented Substance Use Programme (COSUP) used tramadol for opioid withdrawal management during the initial COVID-19 response. Aim: To describe demographics, route of heroin administration and medication-related experiences amongst people accessing tramadol for treatment of opioid withdrawal.Setting: Three community-based COSUP sites in Mamelodi (Tshwane, South Africa). Methods: A retrospective cross-sectional study was conducted. Data were collected using an interviewer-administered paper-based tool between April and August 2020. Descriptive statistics were used to analyse data. Results: Of the 220 service users initiated onto tramadol, almost half (n = 104, 47%) were not contactable. Fifty-eight (26%) people participated, amongst whom most were male (n = 55, 95%). Participants' median age was 32 years. Most participants injected heroin (n = 36, 62.1%). Most participants experienced at least one side effect (n = 47, 81%) with 37 (64%) experiencing two or more side effects from tramadol. Insomnia occurred most frequently (n = 26, 45%). One person without a history of seizures experienced a seizure. Opioid withdrawal symptoms were experienced by 54 participants (93%) whilst taking tramadol. Over half (n = 38, 66%) reported using less heroin whilst on tramadol. Conclusion: Tramadol reduced heroin use but was associated with withdrawal symptoms and unfavourable side effects. Findings point to the limitations of tramadol as opioid withdrawal management to retain people in care and the importance of access to first-line opioid agonists.

ABSTRACT

Abstract Whole-body bone scintigraphy (WB-BS) is used for detecting and monitoring metastatic spread of prostate cancer (PCa) and to investigate bone pain episodes. To investigate the impact of a positive WB-BS on pain-relieving medicine prescription in PCa patients, a single-center, retrospective cohort study with PCa patients classified as positive for bone metastases (BM) by WB-BS was conducted. Demographic, clinical, and ambulatory pain-relieving medicine prescription data were evaluated. Pain-relieving medicines were categorized according to the WHO 'Analgesic Ladder'. Regimens adopted before and after WB-BS were compared. Differences were considered significant at p<0.05. A total of 180 PCa patients were diagnosed with BM, 64.4% of whom were ≥65 years of age. Thirty-three patients were prescribed analgesics only after WB-BS, mostly including NSAIDs and weak opioids. Pain-relieving prescription changed after WB-BS in patients with prescriptions before and after WB-BS, with a reduction in NSAIDs and adjuvants and an increase in weak and strong opioids. In addition, 40% of patients with WHO analgesic step 1 drugs and 21.7% of patients with WHO step 2 drugs before WB-BS changed to other WHO steps after WB-BS. Pain-relieving prescriptions changed after a positive WB-BS, providing evidence that it could contribute to clinical management of painful metastatic PCa patients.

ABSTRACT

Abstract Vascular ulcers (VU) constitute a major cause of pain and disability, and significantly compromise quality of life. VU have a natural tendency to become chronic and in many cases exhibit anunsatisfactoryresponse to many of the standard therapeutic options.The case of a 73 year-old Caucasian female with severe pain and poorly-controlled pain (Visual Analogic Scale-VAS- of 8-9) due to three lower leg long-standing VUs is reported and discussed herein. The patient was treated with topical instillations of undiluted sevoflurane as per institutional off-label protocol (starting doses of 1mL/cm2 twice a day, and up-titrated according to response to a maximum of 7 mL twice daily). The VAS score dropped to 0-1 shortly after initiation of therapy and remained stable throughout treatment up until the closure of the observations. Subsequently, opioid therapy was gradually tapered down and ultimately abandoned.Sevoflurane application resulted on adequate and sustained pain management of refractory VU, with no significant side effects. On account of its beneficial effectivity and safety profiles, topical sevoflurane emerges as an add-on alternative for the long-term management of VU, and potentially other painful conditions.

ABSTRACT

Introducción: El efecto del sulfato de magnesio como adyuvante de la analgesia en la práctica de diferentes intervenciones quirúrgicas es un tema en debate y estudio constante con el fin de probar su eficacia y seguridad en la mejora de la evolución posoperatoria de los pacientes. Objetivo: Evaluar la efectividad y seguridad del sulfato de magnesio como ahorrador de opioides en la anestesia general de pacientes intervenidos por cirugía mayor abdominal. Métodos: Estudio cuasiexperimental, prospectivo, longitudinal realizado en 44 pacientes del Hospital Universitario "General Calixto García", desde diciembre de 2019 hasta diciembre de 2020. Se crearon dos grupos, un grupo estudio (sulfato de magnesio) y otro control. Se evaluó la analgesia intraoperatoria y posoperatoria, el consumo intraoperatorio de fentanil, la necesidad de analgesia de rescate y las complicaciones perioperatorias. Resultados: En los pacientes que se les administró el sulfato de magnesio la tensión arterial media, la frecuencia cardiaca y el índice de shock tuvieron una tendencia a mantenerse por debajo de la media global. El índice de perfusión aumentó y se mantuvo con esa tendencia y tuvieron un menor consumo de fentanil. Conclusiones: La administración de sulfato de magnesio como adyuvante de la anestesia general en pacientes intervenidos por cirugía abdominal mayor electiva, resultó efectiva y segura, pues brindó mayor analgesia perioperatoria, estabilidad hemodinámica, menor consumo de opioides intraoperatorio y menor rescate analgésico posoperatorio que cuando no se usó. La incidencia de complicaciones fue baja y sin repercusión clínica(AU)


Introduction: The effect of magnesium sulfate as an adjunct to analgesia during different surgical interventions is a subject under constant debate and study, with respect to showing its efficacy and safety in improving the postoperative evolution of patients. Objective: To assess the effectiveness and safety of magnesium sulfate as an opioid sparer in general anesthesia with patients undergoing major abdominal surgery. Methods: Quasiexperimental, prospective and longitudinal study carried out, from December 2019 to December 2020, with 44 patients from General Calixto García University Hospital. Two groups were created: a study group (magnesium sulfate) and a control group. Intraoperative and postoperative analgesia, intraoperative fentanyl consumption, requirement of salvage analgesia, as well as perioperative complications were evaluated. Results: In the patients who were administered magnesium sulfate, mean arterial pressure, heart rate and shock index tended to remain below the global mean. The perfusion index increased and maintained this trend, while they had a lower consumption of fentanyl. Conclusions: The administration of magnesium sulfate as an adjunct to general anesthesia in patients undergoing major elective abdominal surgery was effective and safe, as it provided greater perioperative analgesia, hemodynamic stability, less intraoperative opioid consumption and less postoperative analgesic rescue than in the control group. The incidence of complications was low and without clinical repercussions(AU)

ABSTRACT

El paciente oncológico de cuidados paliativos puede presentar una variedad importante de condiciones clínicas que producen sufrimiento y disminución en la calidad de vida; esto se presenta como un reto para el clínico en la identificación y correcto abordaje de los pacientes. El dolor se ha considerado por años como el síntoma cardinal a tratar en el paciente oncológico, donde se deben considerar sus condicionantes fisiopatológicos, la farmacología de las intervenciones, los posibles efectos secundarios y los condicionantes familiares, sociales y personales del dolor, pero a pesar de su relevancia, no es el único síntoma, estando acompañado de un abanico de patologías, como las afectaciones gastrointestinales, pulmonares, vasculares, hematológicas y neurológicas, que favorecen la pérdida de capacidad del paciente y, en muchas ocasiones, la muerte. Se realizó una revisión actualizada en bases de datos como EMBASE, PUBMED, SCIELO, además de la revisión de guías de asociaciones internacionales con el objetivo de acercar a todos los médicos, sin distinguir su especialidad o área de trabajo, al abordaje y manejo del paciente oncológico en cuidado paliativo, favoreciendo la sensibilización con estas patologías y la importancia en el curso de vida de los pacientes.


The palliative care cancer patient can present a significant variety of clinical conditions that produce suffering and a decrease in the quality of life. This is a challenge for the clinician in the identification and correct approach of patients. Pain has been considered for years as the cardinal symptom to be treated in cancer patients, where its pathophysiological factors, the pharmacology of the interventions, possible side effects and the family, social and personal conditions of pain must be considered, but despite its relevance is not the onset of symptoms and is accompanied by a range of pathologies such as gastrointestinal, pulmonary, vascular, hematological and neurological affectations that favor the loss of capacity of the patient and in many cases death. An updated review was carried out in databases such as EMBASE, PUBMED, SCIELO in addition to the revision of guides from international associations with the aim of bringing all doctors without distinguishing their specialty or area of work to the approach and management of cancer patients in palliative care favoring awareness of these pathologies and their importance in the life course of patients.

ABSTRACT

After reading the article entitled "Comparison of subarachnoid opioid mix for cesarean section" published by Isabel Osorio et al., in January 2020; I would like to make the following observations and comments. The number of patients studied (n =71) is surprising considering that the hospital where the research was conducted is a third-level institution and a referral center for high complexity obstetric care. During the duration of the trial (one year, from June 2028 through May 2019) most likely many patients underwent this type of surgical intervention. Is it then possible to consider a potential selection bias? Moreover, the group distribution is not clearly defined, and certainly it was not random: A (29), B (16), C (26)


Después de leer el artículo titulado "Comparación de mezcla de opioides subaracnoides para cesárea" publicado por Isabel Osorio et al., En enero de 2020; Me gustaría hacer las siguientes observaciones y comentarios. Sorprende el número de pacientes estudiadas ( n = 71) si se considera que el hospital donde se realizó la investigación es una institución de tercer nivel y un centro de referencia de atención obstétrica de alta complejidad. Durante la duración del ensayo (un año, desde junio de 2028 hasta mayo de 2019), lo más probable es que muchos pacientes se hayan sometido a este tipo de intervención quirúrgica. ¿Es posible entonces considerar un posible sesgo de selección? Además, la distribución de los grupos no está claramente definida, y ciertamente no fue aleatoria: A (29), B (16), C (26)

ABSTRACT

Cancer related pain is one of the most frequent and relevant symptoms in patients with malignant tumors, causing a huge impact in their quality of life. According to the Chilean Public Health System Technical Report of the Cancer Pain Control and Palliative Care Program 2013-2014, 90% of cancer patients admitted to the Program experienced pain, being moderate or intense in 34%. International and local standards recommend the use of strong opioids (morphine, methadone, or fentanyl) associated with adjuvants such as paracetamol as an initial strategy for pain management. This recommendation assumes that the use of combined analgesics could allow the use of lower opioid doses to obtain similar analgesic effect, decreasing the occurrence of opioid side effects. However, this technical report also describes that there is uncertainty about the impact of paracetamol as an adjuvant in patients with cancer pain who are already receiving strong opioids.

ABSTRACT

Opioid use has reached an epidemic proportion in Canada and the United States that is mostly attributed to excess availability of prescribed opioids for pain. This excess in opioid use led to an increase in the prevalence of opioid use disorder (OUD) requiring treatment. The most common treatment recommendations include medication-assisted treatment (MAT) combined with psychosocial interventions. Clinical trials investigating the effectiveness of MAT, however, have a limited focus on effectiveness measures that overlook patient-important outcomes. Despite MAT, patients with OUD continue to suffer negative consequences of opioid use. Patient goals and personalized medicine are overlooked in clinical trials and guidelines, thus missing an opportunity to improve prognosis of OUD by considering precision medicine in addiction trials. In this mixed-methods study, patients with OUD receiving MAT (n=2,031, mean age 39.1 years [SD 10.7], 44% female) were interviewed to identify patient goals for MAT. The most frequently reported patient-important outcomes were to stop treatment (39%) and to avoid all drugs (25%). These results are inconsistent with treatment recommendations and trial outcome measures. We discuss theses inconsistencies and make recommendations to incorporate these outcomes to achieve patient-centered and personalized treatment strategies.

ABSTRACT

Abstract Introduction Classically, the local anesthetic (LA) has been combined with one lipophilic and another hydrophilic opioid for neuraxial anesthesia in cesarean section. In Colombia, the practice has been the use of morphine hydrochloride with fentanyl, but the occasional shortage of the former triggered an interest in new options. In response to the shortage of morphine in 2017-2018, a contingency plan was developed at the SES Hospital in Caldas, prefilling syringes at the hospital compounding central, with: bupivacaine, morphine and fentanyl (BMF); bupivacaine, fentanyl and hydromorphone (BFH); and bupivacaine and hydromorphone (BH). Hydromorphone has a rapid onset of action, long-lasting effect and is indicated for spinal administration in the safety data sheet; therefore, the advantages of adding fentanyl to this mix are questionable. Objective To compare the clinical analgesic efficacy at the time of the incision and during the first 12 hours after surgery. Methods An observational, analytical study was conducted, using the mixtures BMF, BFH and BH in patients receiving subarachnoid anesthesia for cesarean section. Pain was assessed at the time of the incision, as well as any adverse effects and the pain visual analogue scale over the following 12 hours. Results Of the 71 patients participating in the study, 40.9 % received BMF; 22.5 %, BFH; and 36.6 %, BH. None of the patients experienced pain at the time of the incision. There was no difference in terms of adverse effects among the three groups. The mean difference in the visual analogue scale (VAS) for postoperative pain at 3, 6 and 12 hours was lower in the groups in which hydromorphone was used. Conclusion BFH and BH combinations are comparable to the original preparation in terms of adverse effects, with the advantage of being more effective in controlling postoperative pain.


Resumen Introducción Para anestesia neuroaxial en cesárea, se ha combinado clásicamente el anestésico local (AL) con un opioide lipofílico y otro hidrofílico. En Colombia se ha usado clorhidrato de morfina con fentanilo, pero el ocasional desabastecimiento del primero despertó el interés por nuevas alternativas. En SES Hospital de Caldas se generó un plan de contingencia frente a la escasez de morfina en 2017-2018, pre llenando jeringas en su central de mezclas con: bupivacaína, morfina y fentanilo (BMF); bupivacaína, fentanilo e hidromorfona (BHF); y bupivacaína e hidromorfona (BH). La hidromorfona tiene inicio rápido de acción, efecto prolongado e indicación en ficha técnica por vía espinal, por lo tanto, las ventajas que pudiera generar la adición del fentanilo a esta mezcla son cuestionables. Objetivo Comparar la eficacia analgésica clínica al momento de la incisión y en las primeras 12 horas postoperatorias. Métodos Se realizó un estudio observacional analítico, empleando las mezclas BMF, BHF y BH en pacientes que recibieron anestesia subaracnoidea para cesárea. Se evaluó el dolor a la incisión, los efectos adversos y la escala visual análoga de dolor en las 12 horas siguientes. Resultados De las 71 pacientes del estudio, 40,9 % recibieron BMF; 22,5 %, BHF; y 36,6 %, BH. En ninguna paciente se observó dolor a la incisión. No hubo diferencia en efectos adversos entre los 3 grupos. La diferencia de medias de la escala visual analógica (EVA) para dolor postoperatorio a las 3, 6 y 12 horas, fue menor en los grupos en los que se usó hidromorfona. Conclusiones Las mezclas BHF y BH son equiparables a la preparación tradicional en cuanto a efectos adversos, con la ventaja de ser más efectivas para el control del dolor postoperatorio.

ABSTRACT

Objetivo: El presente trabajo de investigación tuvo como objetivo explorar la eficacia analgésica mediante la comparación de la respuesta analgésica de los parches transdérmicos (PTD) de buprenorfina y fentanilo en dolor oncológico y patrón de uso. Material y Método: Se obtuvieron los datos y variables desde los registros clínicos de pacientes ingresados a la Unidad de Cuidados Paliativos (UCP) del Instituto Nacional del Cáncer (INC) que estaban bajo tratamiento en mayo del 2017. Se incluyó en este estudio a 78 pacientes con PTD, que representan el 13% de los pacientes en control mensual. De estos, 66 estaban bajo tratamiento con buprenorfina y 8 bajo tratamiento con fentanilo. Resultados: Los resultados mostraron que el PTD de buprenorfina se utiliza más frecuentemente que el de fentanilo. El principal motivo de rotación fue dolor no controlado, seguido por imposibilidad de contar con la administración por vía oral. En pacientes con mayores intensidades de dolor somático o visceral se indicó fentanilo y en aquellos con componente neuropático se prefirió el uso de buprenorfina. PTD de fentanilo fue indicado en dosis mayores que buprenorfina, incluso al comparar sus dosis equianalgésicas, siendo la variación de dosis alta para ambos parches: aumentó en promedio 257%. Se logró una mejor respuesta analgésica con buprenorfina, con una variación de intensidad de escala numérica verbal (ENV) de 2,94 y 1,88 puntos de promedio para buprenorfina y fentanilo, respectivamente. Adicionalmente, se presentó mayor reacción local dérmica con fentanilo. Conclusiones: Se evidenció diferencias en patrón de uso y, a diferencia de lo esperado, se obtuvo una mejor eficacia analgésica con buprenorfina. Datos que deben ser corroborados en estudios con mayor número de pacientes bajo tratamiento con fentanilo.


Objective: This study aims to explore analgesic efficacy comparisons of buprenorphine and fentanyl transdermal patches (TDP) in cancer pain and it's usage pattern. Material and Method: Data and variables were collected from patient's clinical reports who were admitted in the National Cancer Institute's (NCI) Palliative Care Unit (PCU) and were under treatment with TDP in May 2017. 78 TDP patients were studied and represented 13% of the monthly control patients in the PCU. Of these, 66 were under buprenorphine treatment and 8 under fentanyl treatment. Results: The results showed that buprenorphine TDP is more frequently used than fentanyl TDP, and the main reason for exchange between them was uncontrolled pain, followed by oral administration impossibility. Fentanyl TDP was indicated in patients with higher somatic or visceral pain intensities and Buprenorphine TDP was preferred in patients with neuropathic pain. Fentanyl TDP was indicated in higher doses than buprenorphine, even when comparing its equianalgesic doses, the dose variation was high for both patches throughout the treatment: it increased on average by 257%. A better analgesic response was achieved with buprenorphine, with a variation of intensity of the Verbal Numerical Scale (VNS) of 2.94 and 1.88 average points, for buprenorphine and fentanyl respectively. Additionally, there was a higher local dermal reaction with fentanyl TDP. Conclusions: Differences in usage patterns were evidenced and, unlike what was expected, better analgesic efficacy was obtained with buprenorphine TDP. This data should be corroborated in receiving fentanyl treatment.

ABSTRACT

The widespread use of opioids to treat chronic pain led to a nation-wide crisis in the United States. Tens of thousands of deaths annually occur mainly due to respiratory depression, the most dangerous side effect of opioids. Non-opioid drugs and non-pharmacological treatments without addictive potential are urgently required. Traditional Chinese medicine (TCM) is based on a completely different medical theory than academic Western medicine. The scientific basis of acupuncture and herbal treatments as main TCM practices has been considerably improved during the past two decades, and large meta-analyses with thousands of patients provide evidence for their efficacy. Furthermore, opinion leaders in the United States favor non-pharmacological techniques including TCM for pain management to fight the opioid crisis. We advocate TCM as therapeutic option without addictive potential and without life-threatening side effects (e.g., respiratory depression) to treat chronic pain patients suffering from opioid misuse. The evidence suggests that: (1) opioid misuse cannot be satisfactorily managed with standard medication; (2) opinion leaders in the United States favor to consider non-opioid and non-pharmacological treatment strategies including those from TCM to treat acute and chronic pain conditions; (3) large meta-analyses provide scientific evidence for the clinical activity of acupuncture and herbal TCM remedies in the treatment of chronic pain. Future clinical trials should demonstrate the safety of TCM treatments if combined with Western medical practices to exclude negative interactions between both modalities.

ABSTRACT

El uso de opioides ha aumentado en forma significativa en las últimas décadas, lo que nos ha permitido conocer sus diversos efectos en el sistema endocrino. Estos efectos están sub diagnosticados, en parte porque los síntomas se confunden con los de la misma enfermedad que lleva al uso de opioides y porque no los buscamos de forma dirigida. El hipogonadismo y la insuficiencia suprarrenal son sus efectos más establecidos, sin embargo, otros efectos como los provocados en el tejido óseo requieren de especial atención. La evaluación de los ejes gonadotropo, adrenal y de la salud ósea debe tenerse en consideración en los usuarios crónicos de opioides, particularmente frente a la presencia de síntomas. La suspensión o reducción del uso de opioides es el primer tratamiento del compromiso endocrinológico.


The use of opioids has increased significantly in recent decades, which has allowed us to understand its effects on the endocrine system. These effects are underdiagnosed, the symptoms are confused with those of the same disease that leads to the use of opioids and we do not look for them in a targeted way. Hypogonadism and adrenal insufficiency are its most established effects, however, other effects such as the ones caused on bone tissue require special attention. Evaluation of gonadotropic and adrenal axes as well as bone health should be taken into consideration in chronic opioid users, particularly in the presence of symptoms. Stopping or reducing opioid use is the first treatment for endocrine compromise.

ABSTRACT

OBJECTIVES: This study was designed to evaluate the clinical efficacy of controlled-release morphine tablets combined with celecoxib in relieving osteocarcinoma-related pain and the effects of the combination on WNK1 expression. METHODS: A total of 110 patients with osteocarcinoma-related pain were selected and divided into two groups based on the treatment administered, including the control group (treated with controlled-release morphine tablets alone) and the study group (treated with a combination of controlled-release morphine tablets and celecoxib). We compared the treatment efficacy, pain level (visual analog scale (VAS)), time of onset of breakthrough pain (BTP), dose of morphine, incidence of adverse events, quality of life (QOL) score, and With-no-lysine 1 (WNK1) expression in the peripheral blood (PB) as determined with qRT-PCR before and after treatment, of the two groups. RESULTS: The total effective rate of the study group was higher than that of the control group, while the VAS score, time of onset of BTP, dose of morphine, incidence of adverse events, QOL score, and relative WNK1 expression in the PB were lower than those of the control group (p<0.05). CONCLUSION: Combination treatment with controlled-release morphine tablets and celecoxib can be extensively used in the clinical setting because it effectively improves the symptoms, QOL score, and adverse effects in patients with osteocarcinoma-related pain.

ABSTRACT

Introdução: O uso de opioides deve ser individualizado e a troca por outro opioide pode ser necessária (rodízio de opioide). Objetivo: Identificar como foi realizado o rodízio de opioide e se o efeito desejado foi atingido em pacientes internados em uma unidade especializada em cuidados paliativos oncológicos. Método: Análise post hoc do estudo de perfil de pacientes internados em um hospital público de cuidados paliativos oncológicos no Rio de Janeiro, entre setembro e novembro de 2016. As internações foram acompanhadas longitudinalmente por revisão de prontuário com coleta diária da escala verbal numérica (EVN). A dor foi considerada controlada quando EVN = 0. Doses, via de administração e rodízio (fármaco e motivo) dos opioides foram observados. O tempo para controle da dor foi calculado quando este foi o motivo. Resultados: Foram observados 104 rodízios de opioides em 90 internações (22,5%), sendo 49% entre opioides fortes e 43% de fraco para forte. Principais motivos foram dor (40%) e dispneia (36%). O tempo para EVN = 0 foi 1,6 dias (+/-1,8; IC95% 1,0-2,1), sendo mais demorado na troca por metadona (média 2,7 dias +/-2,5; IC95% 1,0-4,4). Comparando a dose de morfina oral por equipotência analgésica, houve aumento de 10% na dose do opioide de destino, sendo esse aumento maior quando no rodízio por dispneia (38%). Conclusão: Embora o controle de dor tenha sido superior ao descrito por outros trabalhos, o aumento da dose equipotente do opioide não é corroborado por protocolos. Maior vigilância e outros estudos são recomendados na unidade.


Introduction: The use of opioids must be individualized and changing for another opioid may be necessary (opioid switching). Objective: Identify how the opioid switching was performed and whether the desired effect was achieved in patients admitted at a public palliative oncologic care specialized hospital. Method: Post hoc analysis of the profile study of patients admitted to a public oncologic palliative care hospital in Rio de Janeiro between September and November 2016. Hospitalizations were followed longitudinally by reviewing the charts with daily collection of the numeric rating scale (NRS). Pain was considered controlled when NRS = 0. Doses, route of administration, switch (drugs and motif ) of the opioids were observed. The time for pain control was calculated when this was the reason. Results: 104 opioid switching were observed in 90 hospitalizations (22.5%), 49% of which were strong opioids and 43%, from mild to strong. Main reasons were pain (40%) and dyspnea (36%). The time to NRS = 0 was 1.6 days (+/-1.8; 95% CI 1.0-2.1), taking longer to switch to methadone (mean 2.7 days +/-2.5; 95% CI 1.0-4.4). Comparing the dose of oral morphine by analgesic equipotency, a 10% increase in the target opioid dose occurred, and when rotating due to dyspnea (38%), the increase was greater. Conclusion: Although pain control was higher than described in other studies, the increase in the equipotent dose of opioid is not corroborated by protocols. Extensive surveillance and other studies are recommended in the unit.

Las hospitalizaciones fueron seguidas longitudinalmente mediante la revisión de los registros médicos con la recopilación diaria de la Escala Numérica Verbal (ENV). El dolor se consideró controlado cuando ENV = 0. Se observaron dosis, vía de administración, rotación (fármacos y motivo) de los opioides. El tiempo para el control del dolor se calculó cuando esta fue la razón. Resultados: Se observaron 104 ruedas de opioides en 90 hospitalizaciones (22,5%), con 49% entre opioides fuertes y 43% de débiles a fuertes. Las razones principales fueron dolor (40%) y disnea (36%). El tiempo para ENV = 0 fue de 1,6 días (+/-1,8; IC del 95%: 1,0-2,1), y tomó más tiempo cambiar a metadona (promedio 2,7 días +/-2,5; IC 95% 1,0-4,4). Comparando la dosis de morfina oral para la equipotencia analgésica, hubo un aumento del 10% en la dosis de opioides objetivos, este aumento fue mayor al rotar debido a la disnea (38%). Conclusión: Aunque el control del dolor fue superior al descrito por otros estudios, el aumento en la dosis equipotente de opioide no es compatible con los protocolos. Se recomienda mayor vigilancia y otros estudios en la unidad.
