Critical warm ischemia time point for cardiac donation after circulatory death.

Donation after circulatory death (DCD) represents a promising opportunity to overcome the relative shortage of donors for heart transplantation. However, the necessary period of warm ischemia is a concern. This study aims to determine the critical warm ischemia time based on in vivo biochemical changes. Sixteen DCD non-cardiac donors, without cardiovascular disease, underwent serial endomyocardial biopsies immediately before withdrawal of life-sustaining therapy (WLST), at circulatory arrest (CA) and every 2 min thereafter. Samples were processed into representative pools to assess calcium homeostasis, mitochondrial function and cellular viability. Compared to baseline, no significant deterioration was observed in any studied parameter at the time of CA (median: 9 min; IQR: 7-13 min; range: 4-19 min). Ten min after CA, phosphorylation of cAMP-dependent protein kinase-A on Thr197 and SERCA2 decreased markedly; and parallelly, mitochondrial complex II and IV activities decreased, and caspase 3/7 activity raised significantly. These results did not differ when donors with higher WLST to CA times (≥9 min) were analyzed separately. In human cardiomyocytes, the period from WLST to CA and the first 10 min after CA were not associated with a significant compromise in cellular function or viability. These findings may help to incorporate DCD into heart transplant programs.

Concentrations and determinants of lead, mercury, cadmium, and arsenic in pooled donor breast milk in Spain.

AIM: To measure concentrations of lead (Pb), mercury (Hg), cadmium (Cd), and arsenic (As) in longitudinally collected donor breast milk samples and to determine associated factors. METHODS: Pb, Hg, Cd, and As concentrations were measured in 242 pooled breast milk samples from 83 donors to a Human Milk Bank in Spain, in 2015-2018, determining their association with the donors' sociodemographic profile, dietary and lifestyle habits, and post-partum time, among other factors, and with the nutritional characteristics of samples. Mixed-effect linear regression was used to identify predictors of Hg and As concentrations in breast milk and mixed-effect logistic regression to identify predictors of the presence of Pb and Cd. RESULTS: As was the element most frequently detected in milk samples (97.1%), followed by Hg (81.2%), Pb (50.6%), and Cd (38.0%). Their median breast milk concentrations were 1.49 µg/L, 0.26 µg/L, 0.14 µg/L, and <0.04 µg/L, respectively. Concentrations of As were higher in breast milk from primiparous donors, while Hg was higher in donors with a greater intake of fatty fish and meat and lower in samples collected after a longer post-partum time and with higher lactose content. Detection of Pb was higher among multiparous donors, those gaining weight since before pregnancy, and ex-smokers and was lower in samples collected more recently and from donors with greater intake of red meat and eggs. Cd detection was higher for donors with university education and those with greater intake of fried and canned food and more frequent use of hand cream and was lower for donors with greater bread intake. CONCLUSIONS: These findings reveal relatively high As concentrations, moderate Hg concentrations, and low Pb and Cd concentrations in pooled donor breast milk. Several factors including post-partum time, parity, smoking habit, and the intake of certain food items were associated with the metal content of milk samples.

Local Ketamine Improves Postoperative Analgesia After Third Molar Surgery.

PURPOSE: Evidence exists to support the peripheral analgesic effect of local administration of ketamine (LAK) after third molar surgery. The aim of the present systematic review and meta-analysis was to determine the efficacy of LAK in the control of pain, swelling, and trismus after third molar surgery. MATERIALS AND METHODS: The study design was a systematic review with a meta-analysis of the effect of LAK after third molar surgery. A search in electronic databases was performed from September 2017 to February 2019. Only prospective clinical trials and randomized controlled trials that had evaluated LAK after third molar surgery were included. The meta-analysis was based on the random effects model. The outcome measures evaluated were postoperative acute pain, swelling, and trismus. The estimated overall effect size was a standardized mean difference (SMD). RESULTS: A total of 110 study subjects (men and women aged 18 to 50 years) were evaluated for the analgesic effect. The SMD showed a significant analgesic effect (postoperative pain control) favoring LAK (SMD, -1.7403; 95% confidence interval [CI], -2.45 to -1.04). Evaluation of the anti-inflammatory effect of LAK included 105 study subjects and resulted in significantly less swelling in the first postoperative day (SMD, -0.6169; 95% CI, -1.1654 to -0.0683). However, LAK did not reduce the incidence of trismus after third molar surgery (SMD, -0.7241; 95% CI, -2.2765 to 0.8284). CONCLUSIONS: The use of LAK can reduce the incidence and severity of postoperative pain after third molar surgery and had an anti-inflammatory effect, although only in the first postoperative day. However, LAK had no effect on trismus reduction after third molar surgery.

Prematuro tardío en España: experiencia del Grupo SEN34-36 / Late preterm infants in Spain: Experience of the 34-36 Neonatal Group

INTRODUCCIÓN: Los prematuros tardíos (PT) (34-36 semanas de gestación) son el grupo más amplio de prematuros y menos estudiado hasta ahora. Para mejorar sus cuidados y disminuir el impacto de su mayor morbimortalidad, es primordial conocer su realidad en nuestro país. Población y método: Se recogen prospectivamente variables clínico-epidemiológicas de la población de PT de 34 hospitales participantes, desde el 1 de abril del 2011 al 31 de marzo del 2016. Se comparan con las de la base de datos Conjunto Mínimo de Datos Perinatales para nacidos a término. RESULTADOS: Se estudia a 9.121 PT, el 21,7% de 34, el 30,8% de 35 y el 47,5% de 36 semanas de gestación. Falleció el 2,8‰. El 27,7% fueron embarazos múltiples, el 47,1% identificó enfermedades maternas y el 41,4% patología gestacional. Nacieron por cesárea el 47,9%, el 18,8% de origen no conocido o injustificado. En un 29% no se encontró causa conocida de prematuridad y el 3,1% se reconoció como injustificada. Lactancia materna en el 47%. El 58,6% precisó ingreso en neonatología, el 15,2% en UCIN. El 46,2% codificó algún diagnóstico, los más frecuentes: ictericia (43,5%), hipoglucemia (30%) y trastornos respiratorios (28,7%). CONCLUSIONES: La numerosa muestra de PT estudiada nos ayuda a poner en relieve la mayor morbimortalidad neonatal que presenta esta población y la ineludible relación de su incidencia con la multiparidad, el envejecimiento materno y las aún numerosas inducciones de parto y cesáreas electivas no justificadas

INTRODUCTION: Late preterm (LP) infants (34 -36 weeks of gestation) are the largest group of preterm infants and also the least studied so far. In order to improve their care and reduce the impact of their increased morbidity and mortality, it is essential to know the current situation in Spain. Population and method: Clinical-epidemiological variables of the LP population of 34 participating hospitals were prospectively collected from 1 April 2011 to 31 March 2016, and were then compared with the Minimum Perinatal Data Set for term births in the database. RESULTS: Of the 9,121 LP studied, 21.7% of 34, 30.8% of 35, and 47.5% of 36 weeks of gestation. The mortality rate was 2.8%. More than one-quarter (27.7%) were multiple pregnancies. Maternal disease were identified in 47.1% and 41.4% were pathological gestation. Just under half (47.9%) were by Caesarean section and 18.8% were of unknown origin or unjustified. No known cause of prematurity was found in 29%, and 3.1% were recognized as unjustified?caesarean?. Just under half (47%) of the LP were breastfed, and 58.6% required admission to neonatology, with 15.2% to Neonatal Intensive Care Unit. Coded diagnoses were recorded in 46.2%, with the most frequent being jaundice, 43.5%, hypoglycaemia, 30%, and respiratory disorders with 28.7%. CONCLUSIONS: The large sample of LP studied helps us to highlight the higher neonatal mortality and morbidity that this population suffers and the unavoidable relationship of its incidence with multiparity, maternal aging, and the still numerous inductions of labour and unjustified elective caesareans

Reconstrucción mandibular con injerto costocondral en microsomía hemifacial: reporte de un caso / Mandibular reconstruction with a costochondral graft in hemifacial microsomia: report of a case

La reconstrucción de la articulación temporomandibular (ATM) es una de las cirugías más demandantes para el cirujano maxilofacial y su equipo. Sus objetivos no sólo incluyen la rehabilitación del complejo mecanismo normal de la articulación, sino también la restauración de la simetría facial, mejorar la oclusión y a la vez la masticación. Las funciones de la ATM pueden verse afectadas por diferentes en enfermedades: tumorales, infecciosas, traumáticas y displasias. Éstas son las que constituyen la mayor indicación para la reconstrucción de la ATM, siendo las congénitas asociadas a síndromes las más difíciles de tratar. La microsomía hemifacial es el segundo defecto craneofacial más común, después de la fisura labio palatina. Es un síndrome que, a diferencia de otros, presenta una gran diversidad de opciones de tratamiento, los cuales van a ser aplicados con un enfoque multidisciplinario, ya que los tratamientos pueden ir desde los conservadores o no quirúrgicos como los de ortopedia funcional hasta los quirúrgicos que comprenden la reconstrucción de la ATM y rama mandibular, los cuales en su mayoría se realizan con injertos libres costocondrales. Se presenta el caso de un paciente femenino de cinco años de edad, la cual acude referida al Hospital Central ®Dr. Ignacio Morones Prieto¼ con diagnóstico de microsomía hemifacial severa. Este trabajo se enfoca en describir el protocolo utilizado en nuestra institución para la reconstrucción mandibular de este síndrome desde edades tempranas, lo que beneficiará tanto la función articular como la estética facial.

Temporomandibular joint (TMJ) reconstruction is one of the most demanding surgical procedures performed by maxillofacial surgeons and their teams, whose aim is not only to rehabilitate the complex normal mechanism of the joint but also to restore facial symmetry, and to improve occlusion and chewing. TMJ functions can be affected by various types of maladies: tumors, infectious diseases, trauma, and dysplasias, which constitute the main indicators for TMJ reconstruction, being those associated with congenital syndromes the most difficult to treat. Hemi-facial microsomia is the second most common craniofacial defect after cleft lip and palate. Unlike other syndromes, it presents a wide range of treatment options, all involving a multidisciplinary approach as that they can range from conservative or nonsurgical procedures to functional orthopedics, and surgical procedures in which the TMJ and the mandibular ramus are reconstructed...

CALU polymorphism A29809G affects calumenin availability involving vascular calcification.

Calumenin inhibits gamma-carboxylation of matrix-Gla-protein preventing BMP2-dependent calcification. Our aim was to explore the clinical relevance and functionality of the CALU polymorphism rs1043550, and the relationship of calumenin time-dependent expression profile with the active calcification of human vascular smooth muscle cells (hVSMC). Coronary artery calcium score and lesion severity were assessed by cardiac computed tomography in 139 consecutive low-risk patients genotyped for rs1043550. Polymorphic (G) allele carriage was associated with lower calcium (OR: 6.19, p=0.042). Calcified arteries from CALU 'A' allele carriers undergoing cardiovascular surgery exhibited higher residual calcification, higher calumenin immunostaining and lower matrix-Gla-protein, contrary to 'G' allele carriers. In a luciferase reporter system in vascular cells, polymorphic 'G' allele reduced the mRNA stability by 30% (p < 0.05). Osteogenic high-phosphate media induced active differentiation of hVSMC onto functional osteoblast-like cells as demonstrated by extracellular matrix mineralization and osteoblast markers expression. Calumenin was early over-expressed at day 3 (p < 0.05), but decreased thereafter (mRNA and protein) with implications on gamma-carboxylation system. Calumenin was found released and co-localizing with extracellular matrix calcifications. The CALU polymorphism rs1043550 affects mRNA stability and tissue availability of calumenin thus supporting the protective clinical significance. Calumenin shows a time-dependent profile during induced calcification. These data demonstrate a novel association of vascular calcification with the VSMC phenotypic transition into osteoblast-like cells. Moreover, hyperphosphatemic stimuli render calumenin accumulation in the mineralized extracellular matrix.

Percutaneous coronary intervention in heavily calcified lesions using rotational atherectomy and paclitaxel-eluting stents: outcomes at one year.

Heavily calcified lesions present a challenge for percutaneous coronary intervention. With rotational atherectomy, it is possible to treat these lesions and paclitaxel-eluting stents (PESs) reduce the risk of restenosis over the long term. This retrospective study investigated clinical outcomes with rotational atherectomy and PESs in 50 consecutive patients with heavily calcified lesions. Mortality and target lesion revascularization at 1 year (median, 14 months; interquartile range, 8.75-25.5 months) were recorded. Some 52% of patients were aged over 70 years, 68% were male, 52% had acute coronary syndrome, 80% had multivessel disease and 44% were receiving abciximab. Two patients died in hospital, three died during follow-up (one cardiac death) and 3 (6%) underwent target lesion revascularization. At 1 year, the survival rate free of cardiac death was 94% and the survival rate free of target lesion revascularization was 94%. These findings demonstrate that the combination of rotational atherectomy and PESs gives excellent results in heavily calcified lesions.

Intervencionismo coronario en lesiones severamente calcificadas mediante aterectomía rotacional y stent liberador de paclitaxel: resultados tras un año de seguimiento / Percutaneous coronary intervention in heavily calcified lesions using rotational atherectomy and paclitaxel-eluting stents: outcomes at one year

Las lesiones severamente calcificadas dificultan el intervencionismo coronario. La aterectomía rotacional permite tratar estas lesiones y los stents liberadores de paclitaxel (SLP) reducen la reestenosis a largo plazo. Se evaluó retrospectivamente el resultado de la aterectomía rotacional y los SLP en lesiones severamente calcificadas en 50 pacientes consecutivos. Se estudió la mortalidad y la revascularización de la lesión tratada tras 1 año (mediana, 14 meses; intervalo intercuartílico, 8,75-25,5). El 52% eran mayores de 70 años; el 68%, varones; el 52% tenía síndrome coronario agudo; el 80%, enfermedad multivaso y un 44% recibió abciximab. Hubo 2 muertes intrahospitalarias, 3 en el seguimiento (una cardiaca) y 3 (6%) casos de revascularización de la lesión tratada. A 1 año, la supervivencia libre de muerte cardiaca fue del 94% y la supervivencia libre de revascularización de la lesión tratada, del 94%; esto muestra que la estrategia de SLP y aterectomía rotacional en lesiones severamente calcificadas proporciona excelentes resultados (AU)

Anticoagulant and antiplatelet therapy use in 426 patients with atrial fibrillation undergoing percutaneous coronary intervention and stent implantation implications for bleeding risk and prognosis.

OBJECTIVES: This study was designed to review outcomes in relation to antithrombotic therapy management strategies for patients with atrial fibrillation (AF) who undergo percutaneous coronary intervention (PCI) with stenting. BACKGROUND: There is limited evidence on the optimal antithrombotic therapy management strategies for patients with AF who undergo PCI with stenting. METHODS: We reviewed 426 patients (70.9% men, mean age 71.5 +/- 8.5 years) with AF undergoing PCI with stenting between 2001 and 2006. We recorded clinical and demographic characteristics of the patients, stroke risk factors, and antithrombotic therapy use before PCI and at discharge. Clinical follow-up was performed, and all bleeding episodes, thromboembolism, and major adverse cardiac events (MACE) (i.e., death, acute myocardial infarction, or target lesion revascularization) were recorded. RESULTS: The most commonly associated comorbidities were hypertension (74.5%), diabetes mellitus (40.2%), chronic renal failure (14.9%), and congestive heart failure (26.7%); 80% of patients had >or=2 stroke risk factors. Of the drugs prescribed at discharge, aspirin plus clopidogrel were used in 174 patients (40.8%), whereas 213 patients (50%) were discharged with triple therapy (coumarins, aspirin, and clopidogrel). Complete follow-up was achieved in 87.5% (median 594 days; range 0 to 2,190). The incidence of adverse events was high (36.6%), with major bleeding in 12.3%, thromboembolic events in 4.2%, and MACE in 32.3%. All-cause mortality was high (22.6%). In a multivariate analysis, non-anticoagulation with coumarins increased mortality (17.8% vs. 27.8%; hazard ratio [HR] = 3.43; 95% confidence interval [CI] 1.61 to 7.54; p = 0.002) and MACE (26.5% vs. 38.7%; HR = 4.9; 95% CI 2.17 to 11.1; p < 0.01) In a Cox-regression analysis, non-anticoagulation (p < 0.01) and age (p = 0.02) were independent predictors of MACE. CONCLUSIONS: Patients with AF undergoing PCI with stenting represent a high-risk population because of age, comorbidities, and presence of stroke risk factors. These patients have a high mortality and MACE rate, which is reduced by anticoagulation therapy.
