Tobacco use in lung cancer (LC) patients (p) in Spain
2019
Abstract Background Tobacco use, mainly as cigarette smoking, is the leading cause of lung cancer. Eighty-five percent of LC occur in smokers. Understanding the Spanish smoking habits allows the government to design health care policies against this consumption. To do so, the Grupo Espanol de Cancer de Pulmon (Spanish Lung Cancer Group) made this analysis within the context of the Thoracic Tumor Registry (TTR). Methods The TTR is an observational cohort multicenter study in Spain. The study is conducted according to the Declaration of Helsinki and approved by the institutional review board of each participating site. The registry was approved by the Spanish Drug Agency, as a non-post-author…
Endoscope-assisted keyhole surgery for aneurysms of the anterior circulation and the basilar apex
2000
In the treatment of cerebral aneurysms, preoperative surgical planning and intraoperative strategies for microsurgical approaches are important issues. Within the context of minimally invasive neurosurgery, so-called keyhole approaches, especially those with intraoperative endoscopic assistance, have gained increasing interest, but their application for cerebral aneurysm surgery is a matter of ongoing controversy. The main aspects of keyhole microsurgery, with and without endoscopic assistance, for cerebral aneurysms are explained. To present the keyhole concept, which is based on the preoperative analysis and intraoperative use of pre-existing anatomic windows, this article concentrates on…
Immunoguiding, the Final Frontier in the Immunotherapy of Cancer
2014
T cells play an important role in cancer. This notion is strongly supported by an enormous number of trials on the clinical impact of tumor-infiltrating T cells and studies consequently showing that therapeutic interventions which are based on transfer, activation and expansion, or de-blocking of tumor-specific T cells, which have met with clinical success. To optimally profit from the flow of newly developed immune-based therapeutics aiming to reinforce the systemic and local tumor-specific T-cell response, it will be required to identify biomarkers that provide the rationale to use a particular therapy, that measure the effect of intervention, and that can predict the outcome of a therape…
Impact of Cumulative Dose of Carfilzomib in Combination with Lenalidomide and Dexamethasone in Relapsed Refractory Myeloma Patients: A Retrospective …
2018
Abstract Background: Triplet-based lenalidomide plus dexamethasone (Rd) combinations have become the new standard of care for early relapse and refractory multiple myeloma (RRMM). Carfilzomib is a novel selective proteasome inhibitor (PI) with high efficacy in RRMM. The ASPIRE phase 3 trial showed the superiority of carfilzomib-based triplet (KRd compared to Rd), leading to approval of K for RRMM. However, little is known about safety and efficacy of KRd outside a clinical trial context. Experimental design and aims: In 11 Sicilian Centers belonging to the Sicilian Myeloma Network, from November 2016, when KRd regimen was approved in Italy, to June 2018, 103 consecutive RRMM patients (previ…
Imaging Approach for Evaluation of Focal Liver Lesions
2009
Focal liver lesions are common in the general population. Radiology (imaging) plays a pivotal role for the diagnosis, staging, treatment planning, and follow-up of focal liver lesions. To maximize lesion detection and characterization, imaging needs to be performed with appropriate equipment by using protocols carefully designed on the basis of the underlying clinical context. In addition, the decision of an imaging modality cannot be based on the diagnostic accuracy of an imaging test solely but must also consider patient safety and cost-effectiveness.
Exploring Sodium Glucose Co-Transporter-2 (SGLT2) Inhibitors for Organ Protection in COVID-19
2020
Hospital admissions and mortality from the Coronavirus disease 2019 (COVID-19) pandemic are spreading throughout the world, and second and third waves are thought to be likely. Risk factors for severe COVID-19 include diabetes, chronic kidney disease and cardiovascular disease. Currently, there is no vaccine and no approved therapy. Therapeutic approaches are aimed at preventing viral replication and spread, limiting the impact of the inflammatory overdrive (cytokine storm), preventing thromboembolic complications and replacing or supporting organ function. However, despite organ support, mortality is currently 65% for those receiving advanced respiratory support and 78% for those requiring…
Mitochondrial complex I impairment in leukocytes from polycystic ovary syndrome patients with insulin resistance.
2009
Insulin resistance is a feature of polycystic ovary syndrome (PCOS) and is related to mitochondrial function.Our objective was to assess mitochondrial function by evaluating mitochondrial oxygen (O(2)) consumption, reactive oxygen species (ROS) production, levels of glutathione (GSH), the oxidized glutathione/GSH ratio, TNFalpha levels, and membrane potential. Additionally, we have evaluated mitochondrial complex I as a target of the oxidative stress responsible for PCOS in polymorphonuclear cells.This was a prospective controlled study conducted in an academic medical center.The study population consisted of 20 lean reproductive-age women with PCOS and 20 body composition-matched controls.…
ORBITAL PSEUDOTUMOR CAN MIMIC GRAVES’ OPHTHALMOPATHY
2016
CONTEXT: Orbital pseudotumor (OP) is a benign inflammatory process of the orbit with a large polymorphous lymphoid infiltrate, associated with fibrosis in variable amounts, localized or diffuse. Graves’ ophthalmopathy (GO) is the most common cause of proptosis, unilateral or bilateral. CASE REPORT: We report a patient with unilateral proptosis who was initially treated with antithyroid drugs for an euthyroid Graves disease, but the extension of the investigation infirmed this. The MRI findings (inflammation of fat, muscle and the left lacrimal gland) in conjunction with the biopsy infirmed the initial diagnostic and confirmed the OP. CONCLUSIONS: Orbital pseudotumor is a rare disorder that …
Antiphosphatidylserine Antibodies Affect Rat Yolk Sacs in Culture: a Mechanism for Fetal Loss in Antiphospholipid Syndrome
2004
PROBLEM: A variety of reproductive impairments have been reported in the context of the antiphospholipid syndrome (APS). APS is associated with the presence of antibodies to negatively charged phospholipids that may affect the outcome of pregnancy. METHOD OF STUDY: Rat embryos were cultured within their yolk sacs. The effects of two antiphosphatidylserine monoclonal aPS antibodies (HL5B, RR7F) regarding their influence on growth and apoptotic events of the yolk sacs, as well as on growth and the morphology of the embryos, were studied. RESULTS: Exposure of rat embryos and their yolk sacs to aPS inhibited yolk sac growth. Moreover, increased number of apoptotic events of giant cells in the a…
Phosphodiesterase10A: abundance and circadian regulation in the retina and photoreceptor of the rat.
2011
Phosphodiesterase10A (PDE10A) is a dual specific cyclic nucleotide phosphodiesterase that is specifically enriched in striatum and which has gained attention as a therapeutic target for psychiatric disorders. The present study shows that PDE10A is also highly expressed in retinal neurons including photoreceptors. The levels of PDE10A transcript and protein display daily rhythms which could be seen in preparations of the whole retina. Corresponding changes in PDE10A mRNA were seen in photoreceptors isolated using laser microdissection. This suggests that the expressional control of the photoreceptor Pde10a gene contributes to the observed cyclicity in the amount of retinal PDE10A. The daily …
