Abstract
Durable tolerance in kidney transplant recipients remains an important but elusive goal. We hypothesized that adding B cell depletion to T cell depletion would generate an immune milieu postreconstitution dominated by immature transitional B cells, favoring tolerance. The Immune Tolerance Network ITN039ST Research Study of ATG and Rituximab in Renal Transplantation was a prospective multicenter pilot study of live donor kidney transplant recipients who received induction with rabbit antithymocyte globulin and rituximab and initiated immunosuppression (IS) withdrawal (ISW) at 26 weeks. The primary endpoint was freedom from rejection at 52 weeks post-ISW. Six of the 10 subjects successfully completed ISW. Of these 6 subjects, 4 restarted immunosuppressive medications due to acute rejection or recurrent disease, 1 remains IS-free for over 9 years, and 1 was lost to follow-up after being IS-free for 42 weeks. There were no cases of patient or graft loss. CD19+ B cell frequencies returned to predepletion levels by 26 weeks posttransplant; immunoglobulin D+CD27--naïve B cells predominated. In contrast, memory cells dominated the repopulation of the T cell compartment. A regimen of combined B and T cell depletion did not generate the tolerogenic B cell profile observed in preclinical studies and did not lead to durable tolerance in the majority of kidney transplant recipients.

Abstract
BACKGROUND Cardiovascular risk factors are associated with Alzheimer's Disease (AD) development. However, few studies compare the overall cardiovascular risk with AD biomarkers, and when done, they are mainly performed in moderate cardiovascular risk regions. OBJECTIVES To determine whether cardiovascular risk in older adults is associated with pathological cerebrospinal fluid (CSF) biomarkers of AD in a low cardiovascular risk population. DESIGN This is a cross-sectional study performed between 2017 and 2020. PARTICIPANTS The present work included patients between 50 and 75 years old who were negative for CSF AD biomarkers and had minimum cognitive alterations (controls) and patients with positive CSF AD biomarkers and in early stages of AD (cases). MEASUREMENTS CSF biomarkers included total tau, phosphorylated tau 181 and amyloid ß42 (Aß42). Analytical variables were obtained. ERICE, SCORE2 and Framingham scales were used to calculate the overall patient's cardiovascular risk. The Aß42/Aß40 ratio and neurofilaments were explored when available. RESULTS Two hundred and thirty-three patients were included. Nearly 76% of the sample had AD. AD patients had higher cardiovascular risk than controls (p-value < 0.05). ERICE and SCORE2 were associated with AD presence. Framingham was not. A correlation between elevated cardiovascular risk and higher total tau and NfL levels was observed when adjusted by age. CONCLUSION Cardiovascular risk assessment may be helpful in neurodegenerative disorders detection, as it is associated with CSF total tau and NfL. ERICE and SCORE2 may be useful scales in low cardiovascular risk regions to improve cardiovascular control and prevent neurodegenerative pathologies.

Abstract
Mind-controlled wheelchairs are an intriguing assistive mobility solution applicable in complete paralysis. Despite progress in brain-machine interface (BMI) technology, its translation remains elusive. The primary objective of this study is to probe the hypothesis that BMI skill acquisition by end-users is fundamental to control a non-invasive brain-actuated intelligent wheelchair in real-world settings. We demonstrate that three tetraplegic spinal-cord injury users could be trained to operate a non-invasive, self-paced thought-controlled wheelchair and execute complex navigation tasks. However, only the two users exhibiting increasing decoding performance and feature discriminancy, significant neuroplasticity changes and improved BMI command latency, achieved high navigation performance. In addition, we show that dexterous, continuous control of robots is possible through low-degree of freedom, discrete and uncertain control channels like a motor imagery BMI, by blending human and artificial intelligence through shared-control methodologies. We posit that subject learning and shared-control are the key components paving the way for translational non-invasive BMI.

Abstract
Background and purpose Synchronous bilateral breast cancer (SBBC) accounts for 1–3.5% of breast cancer patients. The aim of this study was to evaluate dosimetric issues, clinical outcomes, and acute toxicities for SBBC patients receiving synchronous bilateral hypofractionated radiotherapy (SBHRT) and to compare them with patients treated with synchronous bilateral normofractionated RT schedule (SBNRT). Materials and methods From April 2016 to March 2020, 39 SBBC patients were referred to our institution. Patients were divided according to their prescription dose: Group A: 50 Gy/25fx (fractions), B: 60–64 Gy/25fx, C: 40.05 Gy/15fx; D: 48 Gy/15fx. Toxicity was evaluated using Common Terminology Criteria for Adverse Events (CTCAE)v.5.0. Results 34 patients were finally evaluated. Median follow-up was 24 months for NF schedule and 9 months for HF schedule. In the HF schedule, no acute side-effects > G2 were observed and no dermatitis was reported in 6th month´s assessments. 95% of patients have no evidence of disease and only 1 patient presented local relapse in the first mammography after RT. No distant failures or deaths were observed. Regarding dosimetric issues, the inter-patient average Dmean for the heart was: Group A: 5.0 Gy (4.6–5.5), Group B: 4.4 Gy (4.1–5.4), Group C: 4.8 Gy (4.5–5.1) and Group D: 5.3 Gy (4.4–5.6). For the lungs, the inter-patient average Dmean was: Group A: 10.8 Gy (9.8–12.2), Group B: 11.5 Gy (11.3–12), Group C: 9.8 Gy (9.3–10.5) and Group D: 10.5 Gy (10–11.3). Conclusions This is the first study reporting the safety, feasibility, and tolerability of 40.05 Gy/15fx over 3 weeks for the treatment of SBBC patients. Further study with larger accrual is mandatory.

Abstract
Research question Is there vertical transmission (from mother to baby antenatally or intrapartum) after SARS-CoV-2 (COVID-19) infected pregnancy? Study design A systematic search related to SARS-CoV-2 (COVID-19), pregnancy, neonatal complications, viral and vertical transmission. The duration was from December 2019 to May 2020. Results A total of 84 studies with 862 COVID positive women were included. Two studies had ongoing pregnancies while 82 studies included 705 babies, 1 miscarriage and 1 medical termination of pregnancy (MTOP). Most publications (50/84, 59.5%), reported small numbers (<5) of positive babies. From 75 studies, 18 babies were COVID-19 positive. The first reverse transcription polymerase chain reaction (RT-PCR) diagnostic test was done in 449 babies and 2 losses, 2nd RT-PCR was done in 82 babies, IgM tests were done in 28 babies, and IgG tests were done in 28 babies. On the first RT-PCR, 47 studies reported time of testing while 28 studies did not. Positive results in the first RT-PCR were seen in 14 babies. Earliest tested at birth and the average time of the result was 22 hours. Three babies with negative first RT-PCR became positive on the second RT-PCR at day 6, day 7 and at 24 hours which continued to be positive at 1 week. Four studies with a total of 4 placental swabs were positive demonstrating SARS-CoV-2 localised in the placenta. In 2 studies, 10 tests for amniotic fluid were positive for SARS-CoV-2. These 2 babies were found to be positive on RT-PCR on serial testing. Conclusion Diagnostic testing combined with incubation period and placental pathology indicate a strong likelihood that intrapartum vertical transmission of SARS-CoV-2 (COVID-19) from mother to baby is possible.

Abstract
Precise analyses of alloreactive T cell phenotype and function can inform both the nature and intensity of adaptive responses to transplant antigens. However, alloreactive T cells are sparse and difficult to detect, particularly in cryopreserved peripheral blood mononuclear cells (PBMCs) and from hypo-responsive individuals. An assay to identify and phenotype alloreactive cells would be particularly valuable, especially for multi-center clinical trials that often store frozen samples for batch analysis. Herein we demonstrate consistent and reproducible alloreactive T cell detection in cryopreserved PBMC following a short-term mixed lymphocyte reaction (MLR). The inherent background expression levels of activation markers on responder T cells were minimized by including a resting period prior to the assay. Stimulator cells were activated before inclusion in the MLR by addition of CD40L and IL-4. The time frame and markers to identify and phenotype alloreactive T cells following stimulation were optimized using short term co-cultures. We defined subsets of CD4+ and CD8+ T cells co-expressing CD69 and either CD154 or CD137 following allostimulation as alloreactive, and further phenotyped these cells with a variety of surface markers such as PD-1, LAG-3, and TIM-3. This assay may allow for the monitoring of donor-specific T cells in transplant recipients with longitudinally collected and cryopreserved PBMCs and provide a useful tool to identify biomarkers associated with tolerance. These biomarkers may add to mechanistic insights in immune recognition of transplanted tissues and/or cells.

Abstract
PURPOSE To study the control graphs applicability for the geometric uncertainties of VMAT treatments in prostate cancer patients, and their use to verify the hypothesis of the data obtained randomness, to apply the margins of Van Herk expression. MATERIAL AND METHODS During the first 5 days of treatment, and then once a week, a Kv CBCT was performed, compared with the simulation CT and adjusted the displacements, to determine the inter-fraction errors. Immediately after radiation therapy, another CBCT was performed (for intra-fraction errors). With these data, the X, R position control charts have been made. The patients, not maintained the deviations within the charts control limits, were called "anomalies". Then, we compared the deviations and margins calculated with the van Herk expression for all patients and for those without anomalies. RESULTS The margins determined show appreciable differences if there were calculated for the total set of patients or for the set of them without anomalies in the control charts. For the overall set of patients, the lateral, longitudinal, and vertical margins were 0.45 cm, 0.52 cm, 0.56 cm, while for the set of patients without anomalies were 0.29 cm, 0.35 cm, and 0.38 cm. CONCLUSIONS The use of control charts allows tracking geometric deviations both inter and intra-fraction, variability real-time control and to detect situations in which it can change for non-random reasons, and require immediate investigation. Maintaining geometric deviations in the control state decreases the margins needed to administer a high dose to CTV in a high percentage of cancer prostate patients.

Abstract
Background:Psoriasis (Ps) and psoriatic arthritis (PsA) have a major impact on patients’ health-related quality of life. Cost of illness of patients with Ps, PsA and both diseases (PsA+Ps) is an important subject as they are associated with a substantial economic impact, with implications from a health management perspective.Objectives:To describe the economic burden of direct non-healthcare and indirect resources of patients with Ps, PsA and PsA+Ps in Spain.Methods:COEPSO (“Evaluation of Costs in patients with Psoriatic Disease”) was an observational, retrospective, cross-sectional study performed in 22 Spanish centers (17 Dermatology and 14 Rheumatology Services), from February 2017 to February 2018, including moderate to severe Ps and PsA patients (with or without Ps), naive to biologics. Direct non-healthcare (social services, home care, physical adaptations, private health and non-health professionals, non-reimbursed and non-pharmaceutical therapies), indirect (loss of productivity) and total costs (direct non-healthcare and indirect costs) related to the disease during the previous year to the study were obtained. Unitary costs (€, 2018) were calculated: out-of-pocket costs were specified directly by patients and loss of productivity costs by means of average salaries based on occupation specified by patients. The information was collected through a case report form filled out by the investigators and a telephone survey administered to the patients.Results:A total of 318 patients were included (196 Ps; 43 PsA and 79 PsA+Ps), mean age 48.7 years and 51.3% males. Metabolic syndrome was the most frequent comorbidity in all groups. The average annual total cost per patient was 1,042.71€ (SD 3,817.55), 1,137.84€ (SD 3,070.39) and 1,830.26€ (SD 5,835.81) for Ps, PsA and PsA+Ps, respectively. The average annual direct non-healthcare cost per patient was 749.57€ (SD 2,393.77), 750.50€ (SD 1,641.82) and 1,247.56€ (SD 4,467.19) for Ps, PsA and PsA+Ps, respectively. The average annual indirect cost per patient was 293.14€ (SD 2,855.27), 387.35€ (SD 2,409.63) and 582.71€ (SD 3,842.12) for Ps, PsA and PsA+Ps, respectively.Patients with combined PsA+Ps had higher annual total cost (direct non-healthcare and indirect costs) than patients with only one of these manifestations separately (75.5% and 60.9% above patients with Ps and PsA, respectively). Total costs in patients with Ps and PsA were similar. Direct non-healthcare costs represent between 66.0% (patients with PsA) to 71.9% (patients with Ps) of total cost. Indirect costs represent between 28.1% (patients with Ps) to 34.0% (patients with PsA) of total cost.Conclusion:PsA and Ps have proved to be diseases with a high economic burden, and the total costs were mainly driven by direct non-healthcare costs. Moreover, although annual total costs in patients with PsA were similar to those of Ps patients, the combination of both manifestations yielded the highest costs suggesting the importance of the increased disease load.Disclosure of Interests:Santos Castañeda: None declared, Esther Vicente Speakers bureau: BMS, Roche., Mar Llamas Velasco: None declared, Javier Sanchez Perez: None declared, José Pardo: None declared, Rita Cabeza-Martínez: None declared, Mercedes Miranda-Fontes: None declared, Juan Márquez: None declared, Jaime Calvo Grant/research support from: Lilly, UCB, Consultant of: Abbvie, Jansen, Celgene, susana armesto: None declared, Isabel Belinchón: None declared, Alejandro Gómez: None declared, María Dolores Miranda: None declared, Silvia Martinez Pardo: None declared, Leticia Merino-Meléndez: None declared, Miguel Angel Casado Consultant of: UCB Pharma, María Yébenes: None declared, Araceli Casado: None declared

Abstract
PURPOSE The aim of the study was to evaluate the effectiveness of fentanyl pectin nasal spray (FPNS) in controlling procedural breakthrough cancer pain (BTCP) in advanced cancer patients undergoing radiotherapy. MATERIALS AND METHODS This study involved 62 advanced cancer patients, with well-controlled background pain, who presented BTCP associated to routine radiotherapy procedures, treated with FPNS according to our protocol of administration. The BPE intensity was measured using a visual analog scale (VAS). RESULTS The BTCP was triggered during the computed tomography simulation (79.3%) or treatment delivery (20.7%). Patients indicated a mean VAS of 8.8 (range 7-10) when attempting the procedure. After 4.5 min (range 2-10) of the first FPNS dose, the majority of patients (85.5%) indicated a VAS of 4.3 (range 2-6). 15.5% of the patients did not respond after 15 min; requiring a second dose. All these patients responded, reporting a mean VAS of 4.2 (range 4-6) after 3.0 min (range 2-5) of the second dose. None of the patients required a third dose, nor reported an AE after the administration of FPNS. CONCLUSIONS In our knowledge, our study is the one of highest recruitment, and with the fastest response of BTCP treated with FPNS reported in advanced cancer patients undergoing radiotherapy. FPNS has proven to be highly effective in reducing the intensity of procedural BTCP in a very short period of time.

Abstract
Abatacept is a CTLA-4-Ig fusion protein that binds to the costimulatory ligands CD80 and CD86 and blocks their interaction with the CD28 and CTLA-4 receptors expressed by T cells, therefore inhibiting T cell activation and function. Abatacept has shown clinical efficacy in treating some autoimmune diseases but has failed to show clinical benefit in other autoimmune conditions. The reasons for these disparate results are not clear and warrant further investigation of abatacept's mode of action. Longitudinal specimens from the Immune Tolerance Network's A Cooperative Clinical Study of Abatacept in Multiple Sclerosis trial were used to examine the effects of abatacept treatment on the frequency and transcriptional profile of specific T cell populations in peripheral blood. We found that the relative abundance of CD4+ T follicular helper (Tfh) cells and regulatory T cells was selectively decreased in participants following abatacept treatment. Within both cell types, abatacept reduced the proportion of activated cells expressing CD38 and ICOS and was associated with decreased expression of genes that regulate cell-cycle and chromatin dynamics during cell proliferation, thereby linking changes in costimulatory signaling to impaired activation, proliferation, and decreased abundance. All cellular and molecular changes were reversed following termination of abatacept treatment. These data expand upon the mechanism of action of abatacept reported in other autoimmune diseases and identify new transcriptional targets of CD28-mediated costimulatory signaling in human regulatory T and Tfh cells, further informing on its potential use in diseases associated with dysregulated Tfh activity.

Abstract
PURPOSE Our aim was investigate whether lymph node uptake is associated with survival and regional relapses, and relapse patterns with respect to the radiotherapy fields in esophageal cancer (EC). MATERIALS AND METHODS The FDG-PET/CT image datasets of 56 patients were analyzed. All patients underwent definitive or neoadjuvant radio/chemotherapy (RCT). All patients suffering from persistent or recurrent local/regional-only disease after RCT were considered for salvage resection. Patients with adenocarcinoma without metastatic disease were considered for planned resection (usually within 3 months of treatment). RESULTS Patients with PET-positive lymph nodes before treatment had a worse overall survival and a shorter disease-free survival than those without PET-positive nodes. They also had worse node and metastatic relapse-free survival. N2 patients had statistically significant poorer outcomes than N1-N0 patients and a better survival if the involved nodes were closer to the esophageal tumor. Involved node location by PET/CT also affected global, nodal and metastatic relapses. In addition, an increment of SUVmax value increased relative risk of death and increased relative risk of node and metastatic relapses. The first site of relapse was metastatic recurrence and, second, local recurrence. The most frequent were "in-field" loco/regional recurrence. We observed a relationship between patients classified-N1 and out-field nodal recurrence (p = 0.024), and between patients-N2 and in-field nodal recurrence. The number of PET-positive nodes was an independent significant prognostic predictor for relapse (p < 0.001). CONCLUSION Our study shows that only FDG-PET/CT can provide prognostic information in EC. Nodal PET/CT uptake influences outcome and relapse location among EC patients.

Abstract
OBJECTIVE Natural killer (NK) cells have been involved in the pathology of different inflammatory and autoimmune disorders. Inflammation is an important regulator of osteoarthritis (OA), but the molecular and cellular mechanisms regulating this process are not well defined. DESIGN To understand the role of NK cells in OA, we have compared the phenotype (CD56 subsets and perforin and granzyme expression) and cytotoxic function of NK cells in peripheral blood and synovial fluid from patients with OA undergoing total knee arthroplasty. RESULTS In contrast to peripheral blood lymphocytes (PBLs), the majority of NK cells from the synovial fluid were CD56brightCD16(-) cells. As expected the expression of the cytolytic mediators perforin and granzyme B in CD56brightCD16(-) cells was low and correlated with a poor cytotoxic potential against K562 sensitive target cells. Surprisingly, this low cytotoxic NK cell subset expressed high levels of granzyme A (a protease recently characterized as a key modulator of inflammation in mouse models) in synovial fluid but not in peripheral blood. The presence of the CD56(+)brightCD16(-) cells expressing granzyme A correlated with increased levels of pro-inflammatory cytokines in synovial fluid from OA patients. CONCLUSION Our results indicate that NK cells from the synovium of patients with OA, which present an immunoregulatory non-cytotoxic phenotype, show different phenotype comparing with NK cells from peripheral blood, especially expressing granzyme A, a pro-inflammatory molecule which may contribute to the establishment of chronic articular inflammation in this type of patients.

Abstract
The hippocampus, a medial temporal lobe structure necessary for the formation of spatial memory, is particularly affected by both normal and pathologic aging. In previous studies, we observed a significant age-related increase in dopaminergic neuron loss in the hypothalamus and the substantia nigra of female rats, which becomes more conspicuous at extreme ages. Here, we extend our studies by assessing spatial memory in 4-6 month-old (young), 26-month-old (old) and 29-32-month-old (senile) Sprague-Dawley female rats as well as the age-related histopathological changes in their dorsal hippocampus. Age changes in spatial memory performance were assessed with a modified version of the Barnes maze test. We employed two probe trials (PTs), one and five days after training, respectively, in order to evaluate learning ability as well as short-term and longer-term spatial memory retention. A set of relevant hippocampal cell markers was also quantitated in the animals by means of an unbiased stereological approach. The results revealed that old rats perform better than senile rats in acquisition trials and young rats perform better than both aging groups. However, during short-term PT both aging groups showed a preserved spatial memory while in longer-term PT, spatial memory showed deterioration in both aged groups. Morphological analysis showed a marked decrease (94-97%) in doublecortin neuron number in the dentate gyrus in both aged groups and a reduction in glial fibrillary acidic protein-positive cell number in the stratum radiatum of aging rats. Astroglial process length and branching complexity decreased in aged rats. We conclude that while target-seeking activity and learning ability decrease in aged females, spatial memory only declines in the longer-term tests. The reduction in neuroblast number and astroglial arborescence complexity in the dorsal hippocampus are likely to play a role in the cognitive deficits of aging rats.

Abstract
Congenital cytomegalovirus (cCMV) infection can reside in many organ systems; however, the virus has a particular predilection towards inhabiting the reticuloendothelial system, especially the liver. Specific studies focusing only on hepatic involvement in infants with cCMV are lacking. We report our experience with a large cohort of infants treated in our hospital clinic due to cCMV and hepatic involvement. Hepatic involvement was defined either as hepatitis (elevated alanine transaminases (ALT) >80 units/L without cholestatic disease) or cholestatic disease (elevated ALT >80 units/L combined with direct bilirubin >2 mg/dL). During the study period, 198 infants were diagnosed with symptomatic cCMV in our clinic. Hepatic involvement was observed in 13 infants (6.6%); 7 (3.5%) with hepatitis and 6 (3%) with cholestatic disease. Maternal primary infection with cytomegalovirus during pregnancy was diagnosed in 7 (53.8%) of the 13 infants, nonprimary in 3 (23.1%) and unknown in 3 (23.1%). Among these 13 infants, central nervous system (CNS) involvement was observed in 11 (84.6%) and hearing impairment in 7 (53.8%). Treatment with an antiviral agent was initiated in all cases. Gradual improvement of hepatic enzymes and cholestasis was observed over a prolonged period. We found that the incidence of hepatic involvement in infants with cCMV is much less frequent than previously reported. The hepatic involvement in these infants may manifest in two different ways, and thus, a high index of suspicion and a stepwise approach will help in correctly diagnosing these infants. Antiviral treatment due to CNS involvement is warranted and prognosis is excellent.

Abstract
BACKGROUND Microbiota through toll-like receptors (TLR) may regulate gastrointestinal motility by activating neuroendocrine mechanisms. We evaluated the influence of TLR2 and TLR4 in the spontaneous contractions and serotonin (5-HT)-induced motor response in mouse ileum, and the 5-HT receptors involved. METHODS Muscle contractility studies to evaluate the spontaneous intestinal motility and the response to 5-HT were performed in the ileum from wild type (WT), TLR2(-/-), TLR4(-/-), and TLR2/4 double knockout (DKO) mice. 5-HT receptor expression was determined by real-time PCR. KEY RESULTS The amplitude of spontaneous contractions in ileum was higher in TLR2(-/-), TLR4(-/-), and TLR2/4 DKO mice with respect to WT. 5-HT evoked concentration-dependent contractile responses in the ileum from TLR2(-/-) and TLR4(-/-) mice similar to WT. However, in ileum from TLR2/4 DKO, 5-HT did not induce any contractile response. Expression of 5-HT2A, 5-HT2B, 5-HT2C, and 5-HT3 receptors resulted increased in ileum from TLR4(-/-) and TLR2/4 DKO. Expression of the 5-HT4 receptor was diminished in TLR2(-/-) and TLR2/4 DKO. High levels of 5-HT7 receptor expression were found in TLR2/4 DKO but not in TLR2(-/-) or TLR4(-/-). In WT and TLR4(-/-), 5-HT2, 5-HT3, 5-HT4, and 5-HT7 receptor antagonists reduced the contractile response evoked by 5-HT. In TLR2(-/-) mice, 5-HT4 antagonist did not reduce the 5-HT response. In TLR2/4 DKO mice, only 5-HT4 and 5-HT7 receptor antagonists reduced the relaxing response induced by 5-HT. CONCLUSIONS & INFERENCES TLR2 and TLR4 signaling may modulate the spontaneous contractions and the serotonin contractile response by acting on 5-HT2, 5-HT3, 5-HT4, and 5-HT7 receptors.

Abstract
PURPOSE Sorafenib is a multikinase inhibitor that targets the MAPK pathway and is currently used for the treatment of hepatocellular and renal carcinoma. Recently, it has been shown that sorafenib is also cytotoxic to multiple myeloma (MM) cells. Here, we have further analyzed the mechanism of sorafenib-induced death in MM cells. METHODS Cell death induced by sorafenib in MM cell lines and in plasma cells from MM patients was evaluated by analysis of gene expression by RT-MLPA and quantitative PCR, protein levels and functionality by Western blot and flow cytometry and gene silencing with siRNA. RESULTS Cell death was characterized by phosphatidylserine exposure, ΔΨm loss, cytochrome c release and caspase activation, hallmarks of apoptosis. DL50 at 24 h ranged from 6 to 10 µM. Ex vivo treatment with 20 µM sorafenib induced apoptosis in around 80 % myeloma cells from six multiple myeloma patients. Sorafenib induced caspase-dependent degradation of Bcl-xL and Mcl-1 proteins, destabilizing the mitochondria and speeding up the development of apoptosis. Sorafenib treatment increased levels of Puma at mRNA and protein level and gene silencing with siRNA confirmed a relevant role for Puma in the induction of apoptosis. Co-treatment with the pan-caspase inhibitor Z-VAD-fmk prevented cell death to a variable degree depending on the cell line. In RPMI 8226 cells, Z-VAD-fmk prevented most of sorafenib-induced death. However, death in MM.1S was only prevented by co-incubation with both Z-VAD-fmk and the RIP1K inhibitor necrostatin-1, indicating that under conditions of inefficient caspase activation, sorafenib induces death by necroptosis. CONCLUSION Our results demonstrate a key role for Puma in the triggering of sorafenib-induced apoptosis and that this drug can also induce death by necroptosis in multiple myeloma cells.

Abstract
Despite the introduction of new antiepileptic drugs and advances in the surgical treatment of epilepsy, an important group of patients still remains uncontrolled by any of these methods. The relatively recent introduction of vagus nerve stimulation is yet another possible treatment for refractory epilepsy. This safe, simple, and adjustable technique reduces the number of seizures and multiple publications support its increasing efficacy and effectiveness, with few adverse effects. The goal of our study is to determine the efficacy of this procedure and the factors predicting a response, particularly in the presence of a temporal lobe discharge on the video electroencephalogram (video-EEG) and magnetic resonance imaging (MRI) lesions. We undertook a retrospective study of all the patients with refractory epilepsy who underwent implantation of a vagus nerve stimulator between 2003 and 2009, and with a minimum follow-up of 6 months. The statistical analysis was done with SPSS for Windows. The stimulator was implanted in 40 patients, of whom 38 had a minimum follow-up of 6 months. In one patient, the device had to be removed due to infection, so the series comprised 37 patients. These were divided into different groups, according to the epidemiologic, clinical, radiologic, and electroencephalographic data. In addition, an analysis of the response was performed. The efficacy of the procedure was established according to the reduction in the mean seizure frequency. The baseline value of these seizures was 80.97 ± 143.59, falling to 37 ± 82.51 at the last revision. The response rate (reduction in seizures ≥ 50 %) at 6 months was 51.4 %, with 62.2 % of the patients showing this reduction at the last evaluation. Significant differences in the response were seen for the variables: baseline frequency of seizures, temporal lobe discharge on VideoEEG and MRI lesions. The mean time to response was 10 months in patients with lower rate of seizures versus 25 months of those with the higher rate (p = 0.024), and the response at 6 months was higher (p = 0.05). Patients with temporal lobe discharge alone or in combination with discharges over other regions had a mean time to response of 11 months versus 26 months in those without temporal discharge (p = 0.037). In the analysis of the MRI, we had seen that at the last revision, 82.4 % of the patients with lesion had achieved response versus 45 % without lesion (p = 0.02). Vagus nerve stimulation reduces the frequency of seizures. A temporal lobe discharge on the video-EEG is an indicator of an early response and the presence of an MRI lesion indicates a late response. Patients with fewer rates of seizures have a better prognosis.
