Ten years since the introduction of therapeutic hypothermia in neonates with perinatal hypoxic-ischaemic encephalopathy in Spain

More than a decade has passed since therapeutic hypothermia (TH) was introduced in Spain; this is the only neuroprotective intervention that has become standard practice in the treatment of perinatal hypoxic-ischaemic encephalopathy (HIE). This article aims to provide a current picture of the technique and to address the controversies surrounding its use. In the last 10 years, TH has been successfully implemented in the vast majority of tertiary hospitals in Spain, and more than 85% of newborns with moderate or severe HIE currently receive the treatment. The factors that can improve the efficacy of TH include early treatment onset (first 6 hours of life) and the control of comorbid factors associated with perinatal asphyxia. In patients with moderate HIE, treatment onset after 6 hours seems to have some neuroprotective efficacy. TH duration longer than 72 hours or deeper hypothermia do not offer greater neuroprotective efficacy, but instead increase the risk of adverse effects. Unclarified aspects are the sedation of patients during TH, the application of the treatment in infants with mild HIE, and its application in other scenarios. Prognostic information and time frame are one of the most challenging aspects. TH is universal in countries with sufficient economic resources, although certain unresolved controversies remain. While the treatment is widespread in Spain, there is a need for cooling devices for the transfer of these patients and their centralisationSe cumple ahora más de una década del inicio de la hipotermia terapéutica (HT) en España, la única intervención neuroprotectora que ha venido a ser práctica estándar en el tratamiento de la encefalopatía hipóxico-isquémica perinatal (EHI). El objetivo de este artículo es ofrecer un panorama actual y presentar las controversias surgidas alrededor de la aplicación de esta terapia. En esta década se ha implantado con éxito la HT en la gran mayoría de los hospitales terciarios de España y más del 85% de los recién nacidos con EHI moderada-grave reciben esta terapia. Entre los aspectos que pueden mejorar la eficacia de la HT están su inicio precoz dentro de las primeras 6 horas de vida y el control de factores comórbidos asociados a la asfixia perinatal. En los pacientes con EHI moderada el inicio después de las 6 horas parece mantener cierta eficacia neuroprotectora. Una duración de la HT mayor de 72 horas o un enfriamiento más profundo no ofrecen mayor eficacia neuroprotectora y aumentan el riesgo de efectos adversos. Persiste la controversia acerca de la sedación durante la HT, la aplicación de esta intervención a los neonatos con EHI leve y en otros escenarios. La información pronóstica y su marco temporal es uno de los aspectos más desafiantes. La HT es universal en países con recursos económicos, aunque existen puntos de controversia no resueltos. Si bien es un tratamiento generalizado en nuestro país, falta disponer de dispositivos para el traslado de estos pacientes y su centralizació

Bortezomib plus melphalan and prednisone in elderly untreated patients with multiple myeloma: updated time-to-events results and prognostic factors for time to progression

New treatment options offering enhanced activity in elderly, newly diagnosed patients with multiple myeloma are required. One strategy is to combine melphalan and prednisone with novel agents. We previously reported an 89% response rate, including 32% complete responses and 11% near complete responses, in our phase 1/2 study of bortezomib plus melphalan and prednisone (VMP) in 60 newly diagnosed multiple myeloma patients with a median age of 75 years. Here, we report updated time-to-events data and the impact of poor prognosis factors on outcome

The therapeutic relationship from the perspective of patients and nurses in the first days of admission: A cross‐sectional study in acute mental health units

The therapeutic relationship (TR) is essential in mental health nursing care and plays a fundamental role in the understanding and treatment of the patient's health status. Despite being a bidirectional construct, limited evidence is available to shed light on this issue in mental health units and even less so in the first days of admission. This study aimed to examine the association and differences between nurses' and patients' perspectives on the establishment of the therapeutic relationship in acute mental health units during the first days of hospitalization. A cross-sectional study was carried out in 12 Spanish mental health units. Data were collected from patients and nurses using the Working Alliance Inventory-Short (WAI-S) questionnaire. A total of 234 cases were analysed, including 234 patients and 58 nurses. The results showed a positive association between nurses' and patients' perspectives on the therapeutic relationship, but also revealed significant differences on each WAI-S dimension. Nurses assigned higher scores compared to patients on the perception of the quality of the therapeutic relationship. The dimensions with the greatest weight from the patients' perspective regarding the quality of the therapeutic relationship were the perception of greater agreement on goals and tasks among nurses. This study demonstrates the importance of establishing shared goals and tasks with nurses from the first days of hospitalization to improve the quality of the therapeutic relationship as perceived by patients. These findings underline the need to consider the different perspectives of both parties to promote a high-quality therapeutic relationship

Quinine doped hybrid sol-gel coatings for wave guiding and optical applications

Pure and quinine doped silica coatings have been prepared over sodalime glasses. The coatings were consolidated at low temperature (range 60-180 A degrees C) preserving optical activity of quinine molecule. We designed a device to test the guiding properties of the coatings. We confirmed with this device that light injected in pure silica coatings is guided over distances of meters while quinine presence induces isotropic photoluminescence. With the combined use of both type of coatings, it is possible to design light guiding devices and illuminate regions in glass elements without electronic circuits

Measurable Residual Disease by Next-Generation Flow Cytometry in Multiple Myeloma

PURPOSE: Assessing measurable residual disease (MRD) has become standard with many tumors, but the clinical meaning of MRD in multiple myeloma (MM) remains uncertain, particularly when assessed by next-generation flow (NGF) cytometry. Thus, we aimed to determine the applicability and sensitivity of the flow MRD-negative criterion defined by the International Myeloma Working Group (IMWG). PATIENTS AND METHODS: In the PETHEMA/GEM2012MENOS65 trial, 458 patients with newly diagnosed MM had longitudinal assessment of MRD after six induction cycles with bortezomib, lenalidomide, and dexamethasone (VRD), autologous transplantation, and two consolidation courses with VRD. MRD was assessed in 1, 100 bone marrow samples from 397 patients; the 61 patients without MRD data discontinued treatment during induction and were considered MRD positive for intent-to-treat analysis. The median limit of detection achieved by NGF was 2.9 × 10-6. Patients received maintenance (lenalidomide ± ixazomib) according to the companion PETHEMA/GEM2014MAIN trial. RESULTS: Overall, 205 (45%) of 458 patients had undetectable MRD after consolidation, and only 14 of them (7%) have experienced progression thus far; seven of these 14 displayed extraosseous plasmacytomas at diagnosis and/or relapse. Using time-dependent analysis, patients with undetectable MRD had an 82% reduction in the risk of progression or death (hazard ratio, 0.18; 95% CI, 0.11 to 0.30; P < .001) and an 88% reduction in the risk of death (hazard ratio, 0.12; 95% CI, 0.05 to 0.29; P < .001). Timing of undetectable MRD (after induction v intensification) had no impact on patient survival. Attaining undetectable MRD overcame poor prognostic features at diagnosis, including high-risk cytogenetics. By contrast, patients with Revised International Staging System III status and positive MRD had dismal progression-free and overall survivals (median, 14 and 17 months, respectively). Maintenance increased the rate of undetectable MRD by 17%. CONCLUSION: The IMWG flow MRD-negative response criterion is highly applicable and sensitive to evaluate treatment efficacy in MM

Trans-Chalcone Attenuates Pain and Inflammation in Experimental Acute Gout Arthritis in Mice

Gouty arthritis is characterized by an intense inflammatory response to monosodium urate crystals (MSU), which induces severe pain and reduction in the life quality of patients. Trans-Chalcone (1,3-diphenyl-2-propen-1-one) is a flavonoid precursor presenting biological activities such as anti-inflammatory and antioxidant proprieties. Thus, the aim of this work was to evaluate the protective effects of trans-Chalcone in experimental gout arthritis in mice. Mice were treated with trans-Chalcone (3, 10, or 30 mg/kg, per oral) or vehicle (Tween 80 20% plus saline) 30 min before intra-articular injection of MSU (100 μg/knee joint, intra-articular). We observed that trans-Chalcone inhibited MSU-induced mechanical hyperalgesia, edema, and leukocyte recruitment (total leukocytes, neutrophils, and mononuclear cells) in a dose-dependent manner. Trans-Chalcone also decreased inflammatory cell recruitment as observed in Hematoxylin and Eosin (HE) staining and the intensity of fluorescence of LysM-eGFP+ cells in the confocal microscopy. Trans-Chalcone reduced MSU-induced oxidative stress as observed by an increase in the antioxidant defense [Glutathione (GSH), Ferric Reducing (FRAP), and 2,2’-Azinobis-3-ethylbenzothiazoline 6-sulfonic acid (ABTS assays)] and reduction in reactive oxygen and nitrogen species production [superoxide anion (NBT assay) and nitrite (NO assay)]. Furthermore, it reduced in vivo MSU-induced interleukin-1β (IL-1β), Tumor necrosis factor-α (TNF-α), and IL-6 production, and increased Transforming growth factor-β (TGF-β) production. Importantly, trans-Chalcone reduced nuclear factor kappa-light-chain-enhancer of activated B cells (NF-κB) activation and thereby the mRNA expression of the inflammasome components Nlrp3 (cryopyrin), Asc (apoptosis-associated speck-like protein containing a CARD), Pro-caspase-1 and Pro-IL-1β. In vitro, trans-Chalcone reduced the MSU-induced release of IL-1β in lipopolysaccharide (LPS)-primed macrophages. Therefore, the pharmacological effects of trans-Chalcone indicate its therapeutic potential as an analgesic and anti-inflammatory flavonoid for the treatment of gout
