Transition of Adolescents With Severe Asthma From Pediatric to Adult Care in Spain: The STAR Consensus

Objective: To assess the degree of consensus among a multidisciplinary expert panel on the transition of adolescents with severe asthma from pediatric to adult care. Methods: A 61-item survey was developed based on guidelines for other chronic diseases, covering transition planning, preparation, effective transfer, and follow-up. A 2-round Delphi process assessed the degree of consensus among 98 experts (49 pediatricians, 24 allergists, and 25 pulmonologists). Consensus was established with ≥70% agreement. Results: Consensus was reached for 42 items (70%). Panelists were unable to agree on an age range for initiation of transition. The main goal during the transition identified by the experts is for adolescents to gain autonomy in managing severe asthma and prescribed treatments. The panelists agreed on the importance of developing an individualized plan, promoting patient autonomy, and identifying factors associated with the home environment. They agreed that the adult health care team should have expertise in severe asthma, biologics, and management of adolescent patients. Pediatric and adult health care teams should share clinical information, agree on the criteria for maintaining biological therapy, and have an on-site joint visit with the patient before the effective transfer. Adult health care professionals should closely follow the patient after the effective transfer to ensure correct inhaler technique, adherence, and attendance at health care appointments. Conclusions: This consensus document provides the first roadmap for Spanish pediatric and adult teams to ensure that key aspects of the transition process in severe asthma are covered. The implementation of these recommendations will improve the quality of care offered to the patient (AU)

Objetivo: Evaluar el grado de consenso con un panel multidisciplinar de expertos sobre la transición del adolescente con asma grave de los servicios de pediatría a atención de adultos. Métodos: Se elaboró un cuestionario de 61 ítems basado en recomendaciones de transición para otras patologías crónicas, abarcando la planificación de la transición, preparación, transferencia efectiva y seguimiento. Se evaluó el nivel de consenso entre 98 expertos (49 pediatras, 24 alergólogos y 25 neumólogos) mediante un proceso Delphi de dos rondas. El consenso se estableció con un acuerdo ≥70%. Resultados: Cuarenta y dos ítems (70%) alcanzaron consenso. Los panelistas no alcanzaron consenso en el rango de edad para iniciar la transición. El principal objetivo a conseguir durante la transición según los expertos fue que el adolescente gane autonomía en el manejodel asma grave y tratamientos prescritos. Asimismo, alcanzaron acuerdo en la importancia de desarrollar un plan individualizado, promover la autonomía del paciente e identificar los factores clave en el entorno familiar. Los especialistas de adultos deben tener experiencia en asma grave y tratamientos biológicos, así como en el manejo de pacientes adolescentes. Los equipos sanitarios de pediatría y de adultos deben compartir la información clínica, consensuar los criterios para mantener la terapia biológica y realizar una visita conjunta con el paciente antes de la transferencia. Los especialistas de adultos deben realizar un seguimiento estrecho del paciente tras la transferencia para asegurar una correcta técnica inhalatoria, el cumplimiento del tratamiento y la asistencia a las citas sanitarias. Conclusiones: Este documento de consenso proporciona la primera hoja de ruta en España para que los equipos especialistas de pediatría y adultos garanticen aspectos clave del proceso de transición en pacientes adolescentes con asma grave.

Toxicity and adherence to treatment for latent tuberculosis infection in patients with hematologic malignancies.

PURPOSE: Oncohematological patients undergoing chemotherapy who have latent tuberculosis infection (LTBI) are at a high risk of developing active tuberculosis (TB). The identification and treatment of these patients can prevent LTBI progressing to active TB. This study analyzed the degree of adherence with and safety of the treatment of latent tuberculosis infection (TLTBI) in oncohematological patients undergoing antineoplastic chemotherapy. METHODS: This is a retrospective study of a cohort of oncohematological patients receiving TLTBI and antineoplastic chemotherapy simultaneously, between January 2007 and June 2010. The proportions of toxicity and adherence to TLTBI in these patients were compared with a non-oncohematological control group, matched for age, sex, and year in which the TLTBI was started. In addition, a minimum 2-year follow-up was carried out for all patients. RESULTS: A total of 105 patients who received TLTBI were included, 21 of whom had received antineoplastic chemotherapy simultaneously. The mean age of the patients was 63 years. There were no significant baseline differences in transaminase values. The percentages of patients completing treatment were 76.2% in the control group and 71.4% in the oncohematological group [risk ratio (RR): 1.07, 95% confidence interval (CI): 0.79-1.43]. The voluntary dropout proportion was similar in both groups (12.3 vs. 11.8%, RR: 1.05, 95% CI: 0.25-4.42). Treatment was discontinued because of toxicity in three oncohematological patients and in 11 patients from the control group (RR: 1.14; 95% CI: 035-3.66). No patient developed TB during the follow-up period. CONCLUSION: The safety of TLTBI is not influenced by simultaneous antineoplastic chemotherapy in oncohematological patients.

The arylalkylamine-N-acetyltransferase (AANAT) acetylates dopamine in the digestive tract of goldfish: a role in intestinal motility.

Melatonin has been found in the digestive tract of many vertebrates. However, the enzymatic activity of the arylalkylamine-N-acetyltransferase (AANAT) and the hydroxindole-O-methyltransferase (HIOMT), the last two enzymes of melatonin biosynthesis, have been only measured in rat liver. Therefore, the first objective of the present study is to investigate the functionality of these enzymes in the liver and gut of goldfish, analyzing its possible daily changes and comparing its catalytic properties with those from the retina isoforms. The daily rhythms with nocturnal acrophases in retinal AANAT and HIOMT activities support their role in melatonin biosynthesis. In foregut AANAT activity also show a daily rhythm while in liver and hindgut significant but not rhythmic levels of AANAT activity are found. HIOMT activity is not detected in any of these peripheral tissues suggesting an alternative role for AANAT besides melatonin synthesis. The failure to detect functional HIOMT activity in both, liver and gut, led us to investigate other physiological substrates for the AANAT, as dopamine, searching alternative roles for this enzyme in the goldfish gut. Dopamine competes with tryptamine and inhibits retinal, intestinal and hepatic N-acetyltryptamine production, suggesting that the active isoform in gut is AANAT1. Besides, gut and liver produces N-acetyldopamine in presence of acetyl coenzyme-A and dopamine. This production is not abolished by the presence of folic acid (arylamine N-acetyltransferase inhibitor) in any studied tissue, but a total inhibition occurs in the presence of CoA-S-N-acetyltryptamine (AANAT inhibitor) in liver. Therefore, AANAT1 seems to be an important enzyme in the regulation of dopamine and N-acetyldopamine content in liver. Finally, for the first time in fish we found that dopamine, but not N-acetyldopamine, regulates the gut motility, underlying the broad physiological role of AANAT in the gut.

Modulation of cellular apoptosis with apoptotic protease-activating factor 1 (Apaf-1) inhibitors.

The programmed cell death or apoptosis plays both physiological and pathological roles in biology. Anomalous activation of apoptosis has been associated with malignancies. The intrinsic mitochondrial pathway of apoptosis activation occurs through a multiprotein complex named the apoptosome. We have discovered molecules that bind to a central protein component of the apoptosome, Apaf-1, and inhibits its activity. These new first-in-class apoptosome inhibitors have been further improved by modifications directed to enhance their cellular penetration to yield compounds that decrease cell death, both in cellular models of apoptosis and in neonatal rat cardiomyocytes under hypoxic conditions.

Winery solid residue revalorization into oil and antioxidant with nutraceutical properties by an enzyme assisted process.

Revalorization of the winery industry residue, grape seed is studied for the production of an oil and defatted meal with nutraceutical properties. Conventional grape seed oil extraction process is carried out by pressing at high temperature affecting the product quality. Oil extraction by cold pressing improves product quality, but it gives a low oil yield. Oil extracted is increased at the pressing stage, when an enzymatic pre-treatment is incorporated in to the conventional process. The yield is determined by determining the residual oil in the pressed cake. Using an enzymatic treatment during 9 hours at 45 degrees C and 50% of moisture, with a mixture of two commercial enzymes grape seed oil extraction yield by cold pressing is raised up to 72%, being a 59.4% increment in comparison to the yield obtained by the control, without enzymes. The defatted meal by enzimatic assisted process improves its phenolic compounds between 2 and 4 times, depending on the conditions of phenolics extraction in comparison to the control samples.

Primary mesenteric liposarcoma of jejunum: presentation like a cystic mass.

This report describes a rare case of intra-abdominal liposarcoma in a 67-year-old woman. The patient presented at Internal Medicine Unit in May 2004, to study of thyroid pathology. The clinical examination was normal, except for the finding of an asymptomatic mass in the abdomen. The patient knew the existence of tumor since time ago, but she confesses to have only occasional discomfort. In the abdominal ultrasonography a solid mass with large cystic component was detected but relation with other organs was not clear. Computed tomography revealed the presence of a mass with solid and cystic components, in contact with small intestine in the left side of abdomen. A complete resection of tumor arising from mesentery of jejunum was performed successfully with end to end anastomosis. The gross specimen was lobulated and measured 8.5 x 7.5 cm. The histopathology analysis showed proliferating lipoblasts with irregular nuclei on a myxoid background, with plexiform vascular pattern, characteristics belongs to myxoid type liposarcoma. The patient is alive and well one year after removal of tumor. The uncommon site and the exceptional cystic morphology of tumor are discussed, and so it must be included the primary mesenteric liposarcoma in the differential diagnosis of intra-abdominal tumors with cystic large areas.

Pancreatitis hipertrigliceridémica y embarazo / Hypertriglyceridemic pancreatitis in pregnancy

Una mujer de 33 años, secundípara, con antecedentes de hipertrigliceridemia familiar que se agravó en el embarazo anterior y diabetes gestacional, fue ingresada en la 36 semana de gestación por dolor abdominal difuso, vómitos, febrícula y mal estado general. La muestra de sangre era de aspecto lipémico, lechoso-rosado, con una concentración de triglicéridos plasmáticos de 2173 mg/dl, colesterol de 320 mg/dl, amilasa de 801 U/l, LDH 650 U/l, creatinina 1,5 mg/dl, glucemia de 380 mg/dl y leucocitosis con desviación a la izquierda. Fue diagnosticada de pancreatitis aguda, y por signos de sufrimiento fetal se le realizó una cesárea bajo anestesia general con propofol, succinilcolina, sevoflurano y tras el pinzamiento del cordón rocuronio y fentanilo. El recién nacido nació sano y la paciente evolucionó favorablemente con tratamiento conservador. La incidencia de la pancreatitis en el embarazo es baja, pero de morbimortalidad elevada. La etiología más habitual es la patología del tracto biliar, aunque alteraciones metabólicas poco frecuentes como la hiperlipidemia pueden actuar ocasionalmente como factor desencadenante. Hay que destacar la importancia del diagnóstico y tratamiento precoz de estos procesos como clave para el mejor pronóstico en quirófano y en su seguimiento en la Unidad de Reanimación (AU)

[Early extubation with caudal morphine after pediatric heart surgery]. / Extubación precoz con morfina caudal tras cirugía cardíaca pediátrica.

OBJECTIVES: To analyze the viability of immediate extubation of children after corrective surgery for congenital heart defects with extracorporeal membrane oxygenation using an anesthetic technique involving caudal morphine, and to study the effect on length of stay in the pediatric intensive care unit (PICU) or elsewhere in the hospital. MATERIAL AND METHODS: Twenty-nine ASA I-II patients without coagulation alterations undergoing surgery to correct simple heart defects were selected for extubation after surgery. Anesthesia was provided with with sevoflurane, midazolam, rocuronium, fentanil (maximum dose 10 micrograms/Kg) and a bolus of caudal morphine (50-60 micrograms/Kg) after anesthetic induction. Patient characteristics, type of surgery, times of extracorporeal circulation and of ischemia, arterial blood gases upon arrival in the PICU, postoperative complications and quality of analgesia were the variables analyzed. We also compared length of stay in the PICU and hospital for the study group and for a historical control group of 23 patients who had no received caudal morphine or been selected for early extubation. RESULTS: All patients were extubated satisfactorily in the operating room. None required reintubation or reoperation. Postoperative pain was controlled with metamizol alone for 79.3%. No episodes of respiratory depression or neurological complications were observed. PICU and hospital stays were significantly shorter in the study group than in the control group. CONCLUSIONS: Of patients undergoing simple corrective heart surgery with extracorporeal membrane oxygenation immediate extubation did not increase postoperative morbimortality and shortened the hospital stay. A single dose of caudal morphine provided optimum conditions for extubation and good control of postoperative pain. Strict measures must be taken, however, to avoid postpuncture bleeding.

Extubación precoz con morfina caudal tras cirugía cardíacapediátrica / Early exttubation with caudal morphine after pediatric heart surgery

OBJETIVO: Analizar la viabilidad y la influencia en la estancia en la Unidad de Cuidados Intensivos Pediátricos (UCIP) y en el hospital de la extubación inmediata de niños sometidos a corrección de cardiopatías congénitas bajo circulación extracorpórea (CEC) utilizando una técnica anestésica basada en la administración de morfina caudal. MATERIAL Y MÉTODOS: 29 pacientes ASA I-II, sin alteraciones de la coagulación y sometidos a corrección de una cardiopatía simple, fueron seleccionados para ser extubados tras la intervención. La anestesia se realizó con sevoflurano, midazolam, rocuronio, fentanilo (dosis máxima de 10 µg/Kg) y bolo de morfina caudal (50-60 µg/Kg) tras la inducción anestésica. Se analizaron las variables demográficas, tipo de cirugía, tiempo de CEC y de isquemia, gasometría arterial a su llegada a UCIP, complicaciones postoperatorias y grado de analgesia. Asimismo se compararon las estancias en la UCIP y en el hospital con las de un grupo control histórico de 23 pacientes a los que no se administró morfina caudal ni hubo intencionalidad de conseguir su extubación precoz. RESULTADOS: Todos los pacientes fueron extubados satisfactoriamente en quirófano. Ninguno requirió reintubación o reintervención. En el 79,3 por ciento de los casos el dolor se controló sólo con metamizol durante el postoperatorio. No se registraron episodios de depresión respiratoria ni complicaciones neurológicas. La estancia en UCIP y hospitalaria fueron significativamente más bajas que en el grupo control. CONCLUSIONES: La extubación inmediata de pacientes intervenidos por cardiopatía simple bajo CEC no aumentó la morbimortalidad postoperatoria y acortó la estancia hospitalaria. La morfina caudal en dosis única proporcionó unas condiciones óptimas para la extubación y un buen control del dolor postoperatorio, aunque deben extremarse las precauciones para prevenir un sangrado postpunción (AU)

[Hypertriglyceridemic pancreatitis and pregnancy]. / Pancreatitis hipertrigliceridémica y embarazo.

A 33-year-old secundipara with a history of gestational diabetes and familial hypertriglyceridemia exacerbated during her previous pregnancy was admitted in the 36th week of gestation with diffuse abdominal pain, vomiting, low-grade fever, and general malaise. A blood sample had a lipemic, milky-pink appearance and plasma concentrations were as follows: triglycerides 2173 mg/dL, cholesterol 320 mg/dL, amylase 801 U/L, lactate dehydrogenase 650 U/L, creatinine 1.5 mg/dL, glucose 380 mg/dL, and left-shifted white cells. Acute pancreatitis was diagnosed and owing to signs of fetal distress, a cesarean was performed under light general anesthesia with propofol, succinylcholine, and sevoflurane. After the umbilical cord was cut, rocoronium and fentanyl were administered. The neonate was healthy and the patient's condition evolved favorably with conservative treatment. The incidence of pancreatitis during pregnancy is low but related morbidity and mortality are high. The usual cause is biliary tract disease, although rare metabolic alterations such as hyperlipidemia may occasionally act as the trigger. Early diagnosis and treatment are the keys to successful surgery and postoperative recovery.

Molecular typing by pulsed-field gel electrophoresis of Spanish animal and human Listeria monocytogenes isolates.

A total of 153 strains of Listeria monocytogenes isolated from different sources (72 from sheep, 12 from cattle, 18 from feedstuffs, and 51 from humans) in Spain from 1989 to 2000 were characterized by pulsed-field gel electrophoresis. The strains of L. monocytogenes displayed 55 pulsotypes. The 84 animal, 51 human, and 18 feedstuff strains displayed 31, 29, and 7 different pulsotypes, respectively, indicating a great genetic diversity among the Spanish L. monocytogenes isolates studied. L. monocytogenes isolates from clinical samples and feedstuffs consumed by the diseased animals were analyzed in 21 flocks. In most cases, clinical strains from different animals of the same flock had identical pulsotypes, confirming the existence of a listeriosis outbreak. L. monocytogenes strains with pulsotypes identical to those of clinical strains were isolated from silage, potatoes, and maize stalks. This is the first study wherein potatoes and maize stalks are epidemiologically linked with clinical listeriosis.
