In-Vitro and Ex-Vivo Evaluation of Transfersomal Gel of Methotrexate

Abstract Methotrexate on its oral and intravenous administration results in unwanted adverse effects. This drawback can be overcome by transdermal delivery because of its painless objective for systemic drug administration. Transfersomes are ultra-deformable vesicles with the flexibility to reach deeper tissues of the skin. The objective of this research work was to develop methotrexate transfersomal gel by thin film hydration technique, evaluated for entrapment efficiency, deformability, mean vesicle size, and stability, and incorporated into carbopol gel for ease of handling and skin applicability for a longer period of retention on skin. MTX-TFS gel & conventional gel were characterized for consistency, transparency, viscosity, and pH. Ex-vivo skin permeation studies were performed using abdominal goat skin and drug release kinetic parameters and transdermal flux were calculated using mathematical models. The results indicate that MTX was successfully entrapped (84.77 ± 2.35 %w/w) in transfersomes having 240±1.6 nm vesicle sizes and 27.13±0.7 deformability index. The gel was permeated through the skin at a rate of 28.12±2.58 µg/cm2/hr as compared to the conventional gel (10.35±2.14 µg/cm2/ hr). From the study, it was concluded that the MTX-TFS gel can be used as a possible substitute for the conventional formulation for transdermal drug delivery due to 3 times improvement in transdermal flux.

Bicarbonato de sodio intravenoso ¿Cuándo, cómo y por qué utilizarlo? / Intravenous sodium bicarbonate. When, how and why to use it?

Severe metabolic acidosis is defined by a pH < 7.2 with HCO3− < 8 mE- q/L in plasma. Its best treatment is to correct the underlying cause. However, acidemia produces multiple complications such as resistance to the action of catecholamines, pulmonary vasoconstriction, impaired cardiovascular function, hyperkalemia, immunological dysregulation, respiratory muscle fatigue, neurological impairment, cellular dysfunction, and finally, it contributes to multisystemic failure. Intravenous NaHCO3 buffers severe acidemia, preventing the associated damage and gains time while the causal disease is corrected. Its indication requires a risk-benefit assessment, considering its complications. These are hypernatremia, hypokalemia, ionic hypocalcemia, rebound alkalosis, and intracellular acidosis. For this reason, therapy must be "adapted" and administered judiciously. The patient will require monitoring with serial evaluation of the internal environment, especially arterial blood gases, plasma electrolytes, and ionized calcium. Isotonic solutions should be preferred instead of hypertonic bicarbonate. The development of hypernatremia must be prevented, calcium must be provided for hypocalcemia to improve cardiovascular function. Furthermore, in mechanically ventilated patients, a respiratory response similar to the one that would develop physiologically, must be established to be able to extract excess CO2 and thus avoid intracellular acidosis. It is possible to estimate the bicarbonate deficit, speed, and volume of its infusion. However, the calculations are only for reference. More important is to start intravenous NaHCO3 when needed, administer it judiciously, manage its side effects, and continue it to a safe goal. In this review we address all the necessary elements to consider in the administration of intravenous NaHCO3, highlighting why it is the best buffer for the management of severe metabolic acidosis.

Aplicación tópica de ácido tranexámico en urología: ¿Una alternativa de manejo? / Topical Application of Tranexamic Acid in Urology: An Alternative Management?

Los agentes antifibrinolíticos, como el ácido tranexámico, por medio de su administración endovenosa se usan en distintos procedimientos quirúrgicos para prevenir la pérdida de sangrado perioperatorio.[1] Este medicamento es un derivado sintético análogo de la lisina que bloquea los sititos de unión de la lisina en el plasminógeno, inhibiendo su conversión a plasmina e interfiriendo en la fibrinólisis.[2] La aplicación del ácido tranexámico para disminuir el riesgo de sangrado ha sido utilizado en procedimientos urológicos como la resección transuretral prostática (RTUP), prostatectomía radical y nefrolitotomía percutánea (NLP),[3] [4] [5] también se emplea para disminuir las hematurias persistentes en pacientes con poliquistosis renal y en otras hematurias macroscópicas de origen urológico.

Antifibrinolytic agents, such as tranexamic acid, by intravenous administration are used in various surgical procedures to prevent perioperative bleeding loss.[1] This drug is a synthetic lysine analog derivative that blocks the lysine binding sites on plasminogen, inhibiting its conversion to plasmin and interfering with fibrinolysis.[2] The application of tranexamic acid to reduce the risk of bleeding has been used in urological procedures such as transurethral resection of the prostate (TURP), radical prostatectomy and nephrolithotomy. The application of tranexamic acid to reduce the risk of bleeding has been used in urological procedures such as transurethral resection of the prostate (TURP), radical prostatectomy and percutaneous nephrolithotomy (PNL),[3] [4] [5] it is also used to reduce persistent hematuria in patients with polycystic kidney disease and other macroscopic hematuria of urological origin.

Efficiency and safety of umbilical cord mesenchymal stromal/ stem cells in multiple sclerosis combined treatment / Eficacia y seguridad de las células madre / estromales mesenquimales del cordón umbilical en el tratamiento combinado de la esclerosis múltiple

SUMMARY: Multiple sclerosis is a demyelinating disease of the nervous system that affects young people of working age and quickly leads to disability. Treatment of this pathology with umbilical cord mesenchymal stem cells is promising, given their immunomodulatory and neurotrophic properties. The study involved 27 patients diagnosed with multiple sclerosis, 12 of whom underwent combined treatment (intravenous and intrathecal administration) of umbilical cord multipotent mesenchymal stromal/stem cells. The effectiveness of treatment was determined by the degree of neurological deficit and spasticity. Combined treatment with umbilical cord mesenchymal stem cells significantly improves the condition of patients with multiple sclerosis and promotes the regression of neurological deficits and spasticity. This treatment is safe, but for a deeper study, it is necessary to continue research in this area.

RESUMEN: La esclerosis múltiple es una enfermedad desmielinizante del sistema nervioso que afecta a los jóvenes en edad laboral y conduce rapidamente a la discapacidad. El tratamiento de esta patología con células madre mesenquimales de cordón umbilical es prometedor, debido a sus propiedades inmunomoduladoras y neurotróficas. En el estudio participaron 27 pacientes diagnosticados de esclerosis múltiple, 12 de los cuales fueron sometidos a un tratamiento combinado (administración intravenosa e intratecal) de células madre / estromales mesenquimales multipotentes del cordón umbilical. La efectividad del tratamiento estuvo determinada por el grado de déficit neurológico y espasticidad. El tratamiento combinado con células madre mesenquimales del cordón umbilical mejora significativamente la condición de los pacientes con esclerosis múltiple y promueve la regresión de los déficits neurológicos y la espasticidad. Este tratamiento es seguro, sin embargo, es necesario continuar investigando en esta area.

Avaliação de soluções eletrolíticas e vias da administração sobre o teor de umidade das fezes de equinos desidratados experimentalmente / Evaluation of electrolyte solutions and administration routes on the moisture content of feces of experimentally dehydrated horses

A ocorrência de processos fisiopatológicos que cursam com desidratação da ingesta no trato gastrointestinal dos equinos é comum na rotina clínica. Fatores como diminuição da motilidade intestinal e sobrecarga intraluminal de conteúdo desidratado podem levar a compactação em segmentos como estômago, ceco e cólons. Este estudo objetivou realizar a comparação entre soluções eletrolíticas enterais hipotônica (SeHIPO) e isotônica (SeISO) e a solução Ringer com lactato de sódio (RL IV) sobre o teor de umidade das fezes de equinos submetidos a um período de desidratação experimental (PD). Foram utilizados seis equinos adultos, todas fêmeas com idades entre 10 e 15 anos, média de 440 kg de peso corpóreo. O PD constou de 36 horas de jejum hídrico e alimentar associadas a duas administrações intravenosas de furosemida, sendo a primeira imediatamente no início (T-36) e a segunda 12 horas após o início do PD. Os tratamentos utilizados foram: SeHIPO e SeISO, ambas administradas por via nasogástrica em fluxo contínuo (HETfc), e RL IV administrada pela via intravenosa. Todos os tratamentos foram administrados a uma taxa de infusão contínua de 15mL kg-1 h-1 durante 8 horas consecutivas. O delineamento experimental utilizado foi o crossover6x3, onde cada animal foi submetido, em sistema de rodízio, aos três tratamentos em momentos distintos. As soluções eletrolíticas enterais demonstraram maior eficácia na recomposição do teor de umidade das fezes quando comparadas à terapia RL IV. A hidratação enteral com soluções isotônicas e hipotônicas administrada em fluxo contínuo são eficazes em restaurar o teor de umidade das fezes, podendo ofertar uma opção econômica, segura e eficiente na reidratação de pacientes e nas afecções que cursam como obstruções intraluminais simples.

The occurrence of pathophysiological processes that curse with digesta dryness in the gastrointestinal tract of horses is common in clinical routine, factors such as decreased intestinal motility and intraluminal overload of dry content can lead to compaction in segments such as cecum and colon. This study aimed to compare a hypotonic enteral solution (SeHIPO), an isotonic enteral solution (SeISO) and a Ringer with sodium lactate solution (RL IV) over the moisture content of equine feces submitted to an experimental dehydration protocol. Six adult horses were used, all females aged between 10 and 15 years, average body weight of 440 kg. The PD consisted of a 36 hours period of water and food fasting associated with two intravenous administrations of furosemide, the first immediately at the beginning (T-36) and the second 12 hours after the beginning of the PD. The treatments used were: SeHIPO (hypotonic enteral solution administered via nasogastric), SeISO (enteral isotonic solution administered via nasogastric) and RL IV (Ringer's solution with sodium lactate administered intravenously), all treatments were administered by continuous infusion at a rate of 15mL kg-1 h-1 for 8 consecutive hours. The experimental design used was the 6x3 crossover, where each animal is submitted, in a rotation system, to the three treatments at different times. Enteral fluid therapy with isotonic and hypotonic solutions administered in continuous flow are effective in restoring the moisture content of feces, and may offer an economical, safe, and efficient option for rehydrating patients and in conditions that progress as simple intraluminal obstructions.

Potential medication incompatibilities in pediatric oncology prescriptions

Introduction: Pediatric oncology patients have a limited number of venous access routes and need a large number of drugs during hospitalization. This study evaluates potential medication incompatibilities (MI) in pediatric oncology prescriptions and identifies possible factors associated with the risk of their occurrence. Methods: This cross-sectional study evaluated prescriptions from a tertiary universitary hospital from December 2014 to December 2015. The association between variables and the risk of potential incompatibilities between drugs was determined by Student's t-test and Pearson's chi-square, considering p < 0.05 significant. The odds ratio was calculated considering a 95% confidence interval for each drug. Results: 385 prescriptions were evaluated. The mean age of 124 patients was 9.22 years old (SD = ± 5.10), and 50.65% were male. The most frequent diagnosis and reason for hospitalization were leukemia (27.30%) and chemotherapy (36.10%). The totally implantable catheter was the most commonly used venous access (61.30%). In 87.5% of prescriptions, there was the possibility of MI, and 2108 incompatibilities were found, considering 300 different combinations between two drugs. Age, diagnosis, reason for hospitalization, and type of venous access were risk factors for potential incompatibilities (p < 0.05). The following drugs present higher risk of potential incompatibilities: leucovorin, sodium bicarbonate, cefepime, diphenhydramine, dimenhydrinate, hydrocortisone, and ondansetron, with a significant odds ratio. Conclusion: The possibility of MI in prescriptions for pediatric oncology patients is frequent. Thus, the identification of risk factors may contribute to patient safety and to the rational use of drugs.

Anti-Snake Venom Properties of Medicinal Plants: A Comprehensive Systematic Review of Literature

Abstract Snakebite is one of the major health issues posing considerable morbidity and mortality. According to an estimate of World Health Organization (WHO) (World health organization, 2021) approximately 5 million people are bitten by several species of snakes resulting in up to 2.5 million envenomation cases annually. The mainstay of treatment for envenomation is intravenous administration of anti-snake venom. Although antivenom neutralizes the systemic effects but it does not relieve the symptoms such as venom-induced hemorrhage, necrosis and nephrotoxicity. Moreover, the use of antivenoms is associated with hypersensitivity reactions including urticaria, anaphylaxis, or serum sickness due to their heterologous property. Furthermore, stringent storage conditions and narrow specificity of antivenoms limit their use in both developed as well as developing countries. In this context, researchers have been searching for natural products and plant extracts to explore their antivenom activity along with anti-myotoxic, anti-hemorrhagic and anti-inflammatory properties. Plant remedies may prove to be an effective alternate for antivenom sera with less adverse events and better tolerability. To the best of our knowledge, this is the first comprehensive review of medicinal plants possessing anti-snake venom activities against certain species of snakes. The current review highlights the investigated plants with their phytochemical analysis to integrate the available information for future research and development of antivenom sera.

Enterite mesentérica como complicação rara do lúpus eritematoso sistêmico / Mesenteric enteritis as a rare complication of systemic lupus erythematosus

A dor abdominal no paciente com lúpus eritematoso sistêmico tem amplo espectro clínico, variando desde condições inespecí- ficas, como diarreia e vômitos, até eventos de importante morbi- mortalidade, como o abdome agudo inflamatório e/ou perfura- tivo. A seguir, descreve-se um caso de paciente do sexo feminino, de 23 anos, internada por dor abdominal associada a vômitos e à diarreia crônica e progressiva. Foi diagnosticada com lúpus eritematoso sistêmico há 2 anos. Durante a internação, evoluiu com quadro de abdome agudo, e foi realizada tomografia compu- tadorizada de abdome, revelando importante edema de parede intestinal difuso. Isso, somado a alterações clínico-laboratoriais, permitiu o diagnóstico de enterite lúpica. Foi realizado tratamen- to conservador, com corticoterapia e terapia de suporte com correção de distúrbios eletrolíticos severos, sendo iniciado ciclo- fosfamida, com resolução dos sintomas gastrintestinais.

Abdominal pain in patients with systemic lupus erythematosus has a broad clinical spectrum, ranging from nonspecific symp- toms, such as diarrhea and vomiting, to events of significant morbidity and mortality, such as acute inflammatory and/or per- forating abdomen. This article describes a case of a 23-year-old female patient hospitalized for abdominal pain, associated with vomiting and progressive chronic diarrhea. She was diagnosed with systemic lupus erythematosus 2 years ago. During hospita- lization, the patient progressed with acute abdomen, and an ab- dominal computed tomography scan was performed, revealing major diffuse intestinal wall edema. This, added to clinical and laboratories alterations, allowed the diagnosis of lupus enteritis. A conservative treatment with corticotherapy and supportive therapy with correction of severe electrolyte disturbances were initiated, as well as the prescription of cyclophosphamide, with resolution of gastrointestinal symptoms.

Acceso venoso difícil en pediatría / Difficult venous access in pediatrics

BACKGROUND: Cannulation of a peripheral venous access is a routine procedure in pediatric patients admitted to the hospital. 50% of the time cannulation on the first attempt is not feasible, so it is necessary to repeat the puncture, resulting in a complex and frustrating procedure. Half of the children admitted to the hospital have a difficult venous access (DIVA). OBJECTIVE: To carry out a review, which provides information about DIVA in pediatrics, how to evaluate and proceed in these patients. DESIGN: DIVA Score considers vein palpability, vein visibility, age and history of prematurity. The score ranges from 0 to 10 points. Values greater than 4 are associated with difficult venous access. There are associated risk factors: obesity, musculoskeletal malformations, chemotherapy treatment, diabetes mellitus, patients on dialysis, limb edema, moderate to severe dehydration, history of difficult venous access, anxiety of the patient and/or parents report that the child is less likely to cooperate. When making the decision to establish a venous access, it should be evaluated whether it is an emergency or not, the characteristics of the medications and infusions, the time of therapy and the anatomical sites for puncture. Ultrasound and transillumination techniques decrease the time to obtain a venous access and increase the success rate on the first attempt. CONCLUSION: The decision to obtain a venous access must take into account the criteria and risk factors for DIVA. The most recognized scale is the DIVA Score.

INTRODUCCIÓN: La canulación de un acceso venoso periférico es un procedimiento rutinario en los pacientes pediátricos que ingresan al hospital. 50% de las veces la canulación al primer intento es frustra, por lo que es necesario repetir la punción resultando el procedimiento complejo y frustrante. La mitad de los niños que ingresa al hospital presentan un acceso venoso difícil (DIVA, sigla derivada de "difficult intravenous access"). OBJETIVO: Realizar una revisión, que entrega información acerca de DIVA en pediatría, cómo evaluar y proceder en estos pacientes. DESARROLLO: DIVA Score considera palpabilidad y visibilidad venosa, edad y antecedente de prematurez. El puntaje va desde 0 a 10 puntos. Valores mayores a 4 se asocian a acceso venoso difícil. Existen factores de riesgo asociados: obesidad, malformaciones osteomusculares, tratamiento con quimioterapia, diabetes mellitus, pacientes en diálisis, edema de extremidades, deshidratación moderada a severa, historia de acceso venoso difícil, ansiedad del paciente y/o padres que refieren que el niño es poco probable que coopere. Al tomar la decisión de establecer un acceso venoso se debe evaluar si es urgencia o no, las características de los medicamentos e infusiones, tiempo de terapia y los sitios anatómicos para punción. La ultrasonografía y las técnicas de transiluminación disminuyen el tiempo de obtención del acceso venoso e incrementan la tasa de éxito en el primer intento. CONCLUSIÓN: En la decisión de obtener un acceso venoso se deben tener en cuenta los criterios y factores de riesgo de acceso venoso difícil. La escala más reconocida es el DIVA Score.

Prevalência de hiperglicemia de estresse em uma unidade de terapia intensiva / Prevalence of stress hyperglycemia in an intensive care unit

Objetivo: Avaliar a prevalência e o manejo da hiperglicemia de estresse em pacientes internados em uma unidade de terapia intensiva. Métodos: Estudo retrospectivo, realizado de janeiro a junho de 2018. Os dados foram obtidos a partir de 582 prontuá- rios eletrônicos, considerando os valores glicêmicos durante a hospitalização, história prévia ou não de diabetes mellitus, causas do internamento, tempo de permanência na unidade de terapia intensiva, presença de complicações durante o internamento e conduta utilizada em caso de hiperglicemia de estresse. Resulta- dos: Dos 582 pacientes internados na unidade de terapia intensi- va, 579 tiveram sua glicemia indicada nos prontuários analisados; 341 (58,9%) apresentaram hiperglicemia em algum momento da internação, sendo a hiperglicemia de estresse caracterizada em 200 pacientes (35%). A duração média de internamento desses pacientes foi de 8,39±10,9 dias, e a causa mais frequente de inter- namento foi devido a pós-operatório por diversas causas, somando 148 indivíduos (74%). Dentro os pacientes, 72 (36%) apresenta- ram alguma complicação. Além disso, 13 casos (6,5%) evoluíram para óbito. Conclusão: Estudos disponíveis sobre alvos de gli- cose em pacientes críticos das unidades de terapia intensiva apresentam difícil interpretação devido às diferenças subs- tanciais no grupo de populações e aos protocolos de gestão de pacientes utilizados em vários centros. Todavia, a prevalência da hiperglicemia de estresse encontrada nesta amostra é se- melhante à de outras casuísticas estudadas. O índice eleva- do de complicações enfatiza a necessidade de padronização nos critérios para diagnóstico e tratamento da hiperglicemia de estresse objetivando melhor prognóstico desses pacientes independentemente da causa do internamento.

Objective: To evaluate the prevalence and management of stress hyperglycemia in patients hospitalized in anintensive care unit. Methods: Retrospective study, carried out from January to June 2018. Data were obtained from 582 electronic medical records, considering glycemic values during hospitalization, existence of previous history of Diabetes Mellitus, causes of hospitalization, length of stay in the intensive care unit, presence of complications during hospitalization, and behavior used in case of stress hyper- glycemia. Results: Of the 582 patients admitted in the ICU, 579 had their glycemia indicated in the charts analyzed: 341 (58,9%) had hyperglycemia in a certain moment of hospitalization, with stress hyperglycemia being present in 200 patients (35%). The average duration of hospitalization of these patients was 8,39 ± 10,9 days, and the most frequent cause of hospitalization was postoperative for various causes, totaling 148 individuals (74%). Of the patients, 72 (36%) presented some type of complication and 13 patients (6,5%) died. Conclusion: Available studies on glucose targets in critical intensive care unit patients are difficult to be interpre- ted because of substantial differences in the study populations and of patient management protocols used at various centers. However, the prevalence of stress hyperglycemia found in this sample is similar to that of other study groups. The high com- plication rate emphasizes the need for standardization of the criteria for diagnosis and treatment of stress hyperglycemia aiming at a better prognosis of these patients regardless of the cause of hospitalization.

Intravenous thrombolysis for acute ischemic stroke with extended time window / 中华医学杂志(英文版)

BACKGROUND@#Intravenous thrombolysis (IVT) is an effective way for treating acute ischemic stroke (AIS). However, its effects have not been established among AIS patients with unclear stroke symptoms or with stroke onset for >4.5 h.@*METHODS@#We searched PubMed, Embase, Web of Science, Cochrane Central Register of Controlled Trials and Google Scholar databases for randomized controlled trials that compared IVT (IVT group) and placebo or usual care (control group [CG]) in AIS patients with disease onset for >4.5 h. The outcomes of interest included the favorable functional outcome (defined as modified Rankin Scale [mRS] scores 0-1) at 90 days, the functional independence (defined as mRS scores 0-2) at 90 days, proportion of patients with symptomatic intracerebral hemorrhage (sICH) and death at 90 days. We assessed the risk of bias using the Cochrane tool. Pre-specified subgroup analyses were performed by age (≤70 years or >70 years), National Institute of Health Stroke Scale (NIHSS, ≤10 or >10) and time window (4.5-9.0 h or >9.0 h).@*RESULTS@#Four trials involving 848 patients were eligible. The risk of bias of included trials was low. Patients in the IVT group were more likely to achieve favorable functional outcomes (45.8% vs. 36.7%; OR 1.48, 95% CI 1.12-1.96) and functional independence (63.8% vs. 55.7%; OR 1.43, 95% CI 1.08-1.90) at 90 days, but had higher risk of sICH (3.0% vs. 0.5%; OR 5.28, 95% CI 1.35-20.68) at 90 days than those in the CG. No significant difference in death at 90 days was found between the two groups (7.0% vs. 4.1%; OR 1.80; 95% CI 0.97-3.34).@*CONCLUSIONS@#Use of IVT in patients with extended time window may improve their functional outcomes at 90 days, although IVT may induce increased risk of sICH. Care of these patients should well balance the potential benefits and harms of IVT.

Estrategias para la prevención de errores en la administración de medicamentos intravenosos / Strategies for the Prevention of Errors in the Administration of Intravenous Medication / Estratégias para a prevenção de erros na administração de medicamentos intravenosos

Los medicamentos que son administrados erróneamente pueden producir efectos adversos, los cuales pueden causar afectaciones en el paciente y gastos adicionales en las instituciones. Los cuatro errores más comunes en la administración de medicamentos por vía intravenosa son dosis incorrectas del medicamento, volumen incorrecto, mezclas incorrectas e incompatibilidad farmacológica. El nivel de conocimiento farmacológico en el profesional de enfermería cobra especial importancia. Objetivo: analizar la literatura disponible sobre estrategias utilizadas para prevenir la ocurrencia de estos errores en la administración de medicamentos intravenosos por parte del personal enfermería desde el año 2010 al 2019. Método: se realizó una revisión integrativa (RI) para dar respuesta a la pregunta: ¿cuál es la evidencia disponible sobre estrategias para la prevención de errores en la administración de medicamentos por vía intravenosa? Se utilizaron bases datos entre las que se encuentran OVID, ScienceDirect, SciELO, Medline Complete, Academic Search Complete, PubMed y Guías de Prácticas Clínicas, con límite de tiempo entre 2010 y 2019. Resultado: se identificaron 17 publicaciones sobre estrategias de prevención de errores en la administración de medicamentos por vía Intravenosa, se clasificaron los resultados en 3 grupos relacionados con dosis, volumen, mezclas e incompatibilidades y con factores extrínsecos del paciente. Conclusiones: el número de estudios en cuanto a la prevención de errores en la administración de los medicamentos intravenosos es reducido al igual que el rigor metodológico; respecto a las estrategias de minimización de errores, prevalece la utilización de dispositivos electrónicos (bombas inteligentes, códigos electrónicos, etiquetado), comunicación asertiva, creación y adherencia a las guías y protocolos (principalmente en fármacos analgésicos y antibióticos) , fortalecimiento de los conocimientos individuales (educación continua, temas farmacológicos y capacitación en habilidades técnicas) y la generación de una estandarización en la preparación y administración de medicamentos intravenosos.

Erroneous intravenous medication administration can produce adverse effects, which can cause affectations in the patient and additional expenses for the institutions. The four most common errors in intravenous medication administration are wrong doses, wrong volume, wrong mixes, and pharmacological incompatibility. The level of pharmacological knowledge in nursing professionals is essential. Objective: to analyze the available literature on strategies used to prevent these errors in the administration of intravenous medications by nursing staff from 2010 to 2019. Method: an integrative review (IR) was carried out to answer the question: what is the available evidence on strategies for preventing errors in the administration of intravenous medication? Databases were used, including OVID, ScienceDirect, SciELO, Medline Complete, Academic Search Complete, PubMed, and Clinical Practice Guidelines, with a period limit between 2010 and 2019. Results: 17 publications were identified on strategies for preventing errors in the administration of intravenous medication. The results were classified into 3 groups related to dose, volume, mixtures,and incompatibilitiesand with factorsextrinsicto the patient.

An attempt to enhance solubility of metoclopramide base by Solid dispersion strategy and its application on development of Transdermal device

Chemotherapy induced nausea and vomiting (CINV) is an issue, which usually occurs in cancer patient. Despite high bioavailability of oral and intravenous administration, these have some drawbacks. The oral route causes hepatic first pass metabolism and intravenous route is invasive in nature. Hence, antiemetic drug by means of transdermal route is necessary to administer in such cases. The aim of the present investigation is to develop suitable Transdermal Therapeutic System (TTS) with an objective to enhance solubility and skin permeability properties of metoclopramide base. Preformulation study begins with an approach to enhance solubility of 40 metoclopramide base by solid dispersion technique. transdermal films were prepared with 41 the solid dispersion as well as with pure drug. Phase solubility study at various temperatures reveals binding constants (Ka, 95-350 M-1 for PVP K30; 56-81 M-1 for HPßCD). Spontaneity of solubilization was justified by AL type linear profiles. The films showed satisfactory diffusion (%), permeation rate and flux after 8 h study. The transdermal patches as prepared were analyzed under FTIR, DSC and SEM. Both solubility and permeability rate in this investigation have been enhanced. So, it can be affirmed that this route would effectively enhance bioavailability

Occurrence of unusual haemoglobinopathies in balochistan: hb sd and hb se - presentation with osteomyelitis / Ocorrência de hemoglobinopatias incomuns no baluchistão: hb sd e hb se - apresentação com osteomielite

ABSTRACT Objective: To describe two cases of unusual variants of sickle cell disease. Case description: We present two cases of sickle cell disease variants (haemoglobinopathies), from unrelated families, in the state of Balochistan (Pakistan). One was diagnosed with sickle cell disease in the haemoglobin electrophoresis, whereas the other was diagnosed with sickle cell SE disease. Both were diagnosed based on the presentation of osteomyelitis. Comments: Haemoglobin SD disease (Hb SD) and haemoglobin SE disease (Hb SE) are rare haemoglobinopathies in the world. The lack of available literature suggests that both are variants of sickle cell disease (SCD), with heterogeneous nature. The prevalence of sickle cell disease with compound heterozygotes was found at a variable frequency in the population of the Asian Southeast. The frequency of osteomyelitis in SCD is 12 to 18%, but its occurrence among variant haemoglobinopathies is little reported. Both reported cases presented with osteomyelitis as a characteristic of the disease presentation.

RESUMO Objetivo: Descrever dois casos de variantes raras da hemoglobinopatia falciforme. Descrição do caso: Apresentamos aqui dois casos de hemoglobinopatias variantes das células falciformes, de famílias não relacionadas, no estado do Baluchistão (Paquistão), sendo um diagnosticado como doença da hemoglobina SD na eletroforese de hemoglobina, enquanto o outro com doença da hemoglobina SE. Ambos foram diagnosticados a partir da apresentação de osteomielite. Comentários: Hemoglobina SD (Hb SD) e hemoglobina SE (Hb SE) são hemoglobinopatias raras no mundo. A escassez de literatura disponível sugere que ambas são variantes da doença falciforme (DF) com natureza heterogênea. A prevalência de hemoglobinopatia falciforme com heterozigosidade composta foi encontrada com frequência variável na população do sudeste asiático. A frequência de osteomielite na DF é de 12 a 18%, mas sua ocorrência entre as hemoglobinopatias falciformes variantes é pouco relatada. Os dois casos reportados apresentaram osteomielite como característica de apresentação da doença.

Objetivo: Avaliar custo-minimização da troca entre as versões intravenosa (IVIg) e subcutânea (SCIg) das imunoglobulinas (Ig) em operadora de saúde com mais de 500.000 vidas. Métodos: Estudo retrospectivo, transversal, descritivo, seguido de custo-minimização entre os pacientes que utilizaram IVIg, de 1º de outubro de 2018 a 30 de setembro de 2019. Simulou-se a troca entre as IVIg e SCIg, objetivando descrever a economia de uma hipotética substituição. Estabeleceram-se como critérios de exclusão: o não pagamento e a liberação com dose acima de 60.000 mg. Após exclusão, calcularam-se as despesas totais, somando-se os custos do produto e taxas de infusão. Resultados: Evidenciou-se que 133 pacientes, totalizando 1.175 liberações, utilizaram IVIg no período avaliado. Identificou-se a utilização de 34.797.500 mg de IVIg, por 10 especialidades, totalizando R$ 12.408.192,50 de despesas. Quando aplicada simulação, há uma potencial economia de recursos de até 29,83%, dependendo da SCIg escolhida. Conclusão: A análise econômica no tratamento com imunoglobulinas evidenciou significativa relevância, pois contribui com o uso adequado da terapêutica garantindo a sustentabilidade do sistema de saúde. Medicamentos subcutâneos apresentam-se como uma opção custo-minimizatória em comparação ao tratamento intravenoso para saúde suplementar brasileira.

Objective: Cost-minimization evaluation of the switch from intravenous (IVIg) to subcutaneous (SCIg) immunoglobulin (Ig) in a Brazilian Health Maintenance Organization (HMO), with more than 500.000 lives. Methods: This is a retrospective, transversal and descriptive study, followed by a cost-minimization analysis among patients using IVIg between 2018, October, 1st and 2019, September, 30th. The simulation was performed supposing the exchange from IVIg to SCIg, in order to calculate possible savings. Exclusion criteria: non-payment (gloss), and infusions with doses above 60.000 miligrams. After exclusion, total expenditures were calculated by summing product and infusion costs. Results: There were133 patients, with1,175 IVIg infusion events in the period evaluated. It was identified the use of 34,797,500 milligrams of IVIg, for 10 specialties, with R$ 12,408,192.50 of final expenditure. The simulation previews hypothetical reduction in the final cost of up to 29.83%, depending on the SCIg brand chosen. Conclusion: The economic analysis in the treatment with immunoglobulins showed significant relevance, as it contributes to the appropriate use of therapy ensuring the sustainability of the health system. Subcutaneous drugs are a cost-minimizing option compared to intravenous treatment for Brazilian HMOs.
