    Migraine is one of the most prevalent and disabling medical diseases in the world. The periaqueductal gray matter and the red nucleus play an important role in its pathogenesis. Our aim was to evaluate the echogenicity of the periaqueductal gray matter and the red nucleus in patients with migraine, by means of transcranial ultrasound. In this cross-sectional study, a group of patients with migraine (according to the International Classification of Headache Disorders) and a group of control subjects with comparable age-and-sex distribution were prospectively included. We evaluated the area and echogenicity of the periaqueductal gray matter and the red nucleus by means of transcranial ultrasound, both bedside and posteriorly analyzed with the medical image viewer Horos. We included 115 subjects: 65 patients with migraine (39 of them with chronic migraine and 26 with episodic migraine), and 50 controls. Median disease duration in patients with chronic migraine was 29 (IQR: 19; 40) years, with a median of 18 (IQR: 14; 27) days of migraine per month. The area of the periaqueductal gray matter was larger in patients with chronic migraine compared to episodic migraine and controls (0.15[95%CI 0.12;0.22]cm 2 ; 0.11[95%CI 0.10;0.14]cm 2 and 0.12[95%CI 0.09;0.15]cm 2, respectively; p = 0.043). Chronic migraine patients showed an intensity of the periaqueductal gray matter echogenicity lower than controls (90.57[95%CI 70.87;117.26] vs 109.56[95%CI 83.30;122.64]; p = 0.035). The coefficient of variation of periaqueductal gray matter echogenicity was the highest in chronic migraine patients (p = 0.009). No differences were observed regarding the area or intensity of red nucleus echogenicity among groups. Patients with chronic migraine showed a larger area of echogenicity of periaqueductal gray matter, a lower intensity of its echogenicity and a higher heterogenicity within this brainstem structure compared to patients with episodic migraine and controls. The echogenicity of the periaqueductal gray matter should be further investigated as a biomarker of migraine chronification.

    Grupo Español de Trasplante Hematopoyético (GETH) and Grupo Español de Linfoma y Trasplante Autólogo (GELTAMO).We performed a retrospective multicenter study including 140 patients with relapsed/refractory (R/R) diffuse large B cell lymphoma (DLBCL) who underwent allogeneic hematopoietic stem cell transplantation (allo-SCT) from March 1995 to November 2018. Our objective was to analyze long term outcomes. Seventy-four percent had received a previous auto-SCT (ASCT) and the median number of lines pre-allo-SCT was 3 (range 1–9). Three year-event free survival (EFS) and overall survival (OS) were 38% and 44%, respectively. Non-relapse mortality (NRM) at day 100 was 19%. Cumulative incidence of grade III–IV acute graft versus host disease (GVHD) at day 100 was 16% and moderate/severe chronic GVHD at 3 years 34%. Active disease at allo-SCT (HR 1.95, p = 0.039) (HR 2.19, p = 0.019), HCT-CI ≥ 2 (2.45, p = 0.002) (HR 2.33, p = 0.006) and donor age >37 years (HR 2.75, p = 0.014) (HR 1.98, p = 0.043) were the only independent variables both for PFS and OS, respectively. NRM was significantly modified by HCT-CI ≥ 2 (HR 4.8, p = 0.008), previous ASCT (HR 4.4, p = 0.048) and grade III–IV acute GVHD on day 100 (HR 6.13, p = 0.016). Our data confirmed that allo-SCT is a curative option for patients with R/R DLBCL, displaying adequate results for fit patients with chemosensitive disease receiving an allo-SCT from a young donor

    Modulation of GSTP1-1 oligomerization by electrophilic inflammatory mediators and reactive drugs

    Glutathione S transferase P1-1 plays a key role in the metabolism of inflammatory mediators and drugs, thus modulating the inflammatory response. Active GSTP1-1 is a homodimer with cysteine residues close to the active site that can undergo oligomerization in response to stress, a process that affects enzyme activity and interactions with signaling and redox-active proteins. Cyclopentenone prostaglandins (cyPG) are endogenous reactive lipid mediators that participate in the regulation of inflammation and may covalently modify proteins through Michael addition. cyPG with dienone structure, which can bind to vicinal cysteines, induce an irreversible oligomerization of GSTP1-1. Here we have characterized the oligomeric state of GSTP1-1 in Jurkat cells treated with 15-deoxy-Δ12,14-PGJ2 (15d-PGJ2). 15d-PGJ2 induces both reversible and irreversible GSTP1-1 oligomerization as shown by blue-native 2D electrophoresis. Interestingly, GSTP1-1 dimers were the main species detected by analytical gel filtration chromatography in control cells, whereas only oligomers, compatible with a tetrameric association state, were found in 15d-PGJ2-treated cells. cyPG-induced GSTP1-1 oligomerization also occurred in cell-free systems. Therefore, we employed this model to assess the effects of endogenous reactive species and drugs. Inflammatory mediators, such as 15d-PGJ2 and Δ12-PGJ2, and drugs like chlorambucil, phenylarsine oxide or dibromobimane elicited whereas ethacrynic acid hampered GSTP1-1 oligomerization or intra-molecular cross-linking in cell-free systems, yielding GSTP1-1 species specific for each compound. These observations situate GSTP1-1 at the cross-roads of inflammation and drug action behaving as a target for both inflammatory mediators and reactive drugs, which induce or reciprocally modulate GSTP1-1 oligomerization or conformation.This work was supported by grants from MINECO SAF2009-11642 and SAF2012-36519 to DP-S and BFU2005-00050, BFU2008-00666 and BFU2009-08977 to MAP and from ISCIII, RETIC RD07/0064/0007 and RD12/0013/0008 to DPS and RD12/0013/0002 to JAGA.Peer Reviewe

    Comparative Study of the Efficacy of EHO-85, a Hydrogel Containing Olive Tree (Olea europaea) Leaf Extract, in Skin Wound Healing

    Olive tree (Olea europaea) leaf extract (OELE) has important antioxidant and anti-inflammatory properties, supporting its use in human clinical practice. We recently designed an amorphous hydrogel called EHO-85 (EHO indicates olive leaf extract in Spanish) containing OELE for skin ulcer treatments. Yet, its effectiveness has not been previously compared with other products used in routine clinical practice. This is necessary to evaluate its potential translation to the human clinic. Thus, in this study, the effect of EHO-85 on healing was evaluated in comparison with treatments containing Indian/Asiatic pennywort (Centella asiatica), hyaluronic acid, or dexpanthenol in a rat model. The speed of wound closure and histological parameters after seven and 14 days were analyzed. All treatments accelerated wound closure, but there were differences between them. Dexpanthenol after seven days produced the highest epithelialization and the lowest inflammation and vascularization. EHO-85 also promoted epithelialization and reduced vascularization. After 14 days, wounds treated with EHO-85 showed less inflammation and higher levels of collagen in the extracellular matrix. This indicates a higher degree of maturity in the regenerated tissue. In conclusion, the effect of EHO-85 on healing was equal to or superior to that of other treatments routinely used in human clinical practice. Therefore, these results, together with previous data on the effects of this hydrogel on ulcer healing in humans, indicate that EHO-85 is a suitable, low-cost, and efficient therapeutic option for wound healing.This research was funded by Ministry of Economy and Competitiveness: INNCORPORA-TU-2011-1886; Department of Health, Regional Government of Andalusia: program for the Reinforcement of Research Activity in the Clinical Management Units of the Andalusian Health Service: A1-0047-2022; Noventure Grupo Ferrer Internacional (Barcelona, Spain): ESTUDIO GC-17-01; MD.C-L. is funded by Foundation for Biomedical Research of Cordoba through a junior postdoctoral contract from regional Ministry of Health (RH-0058-2021) and the European Regional Development Fund (FEDER)
