Pamies Ramón Diana Ibarra Anguita Paula Rodríguez Payá Alvaro Muñoz Abad David Sánchez García mar.a valero revert Beatriz Grau Mirete mar.ano martínez marín Alicia Calero Amaro Lorena Rodríguez Cazalla Javier Gallego Plazas Medical Oncology Department Elche University Hospital Elche (Alicante) Spain General Surgery Department Elche University Hospital Elche (Alicante) Spain General Surgery Department Vega Baja Hospital Orihuela (Alicante) Spain

Background: Localized pancreatic cancer, including resectable (R), borderline resectable (BR) and locally advanced unresectable disease (LAU), is considered in clinical guidelines for diverse treatment options based on clinical trials in selected populations. Hence, exploring with real world evidence (RWE) clinicians’ preferences for treatment options and their results seems pertinent. Methods: In a set of consecutive patients with localized pancreatic cancer assisted in a third level hospital from January 2013 to December 2022, medical records, symptoms, diagnostic process, distribution between subtypes, and treatment plans, with safety and efficacy results, were assessed. Results: A total of 152 patients with localized disease were included (43.4% R, 21.0% BR, 33.6% LAU). The population characteristics exemplified differences between daily practice and clinical trials. Tumor location and symptoms were as expected. Treatment plan was conditioned by PS or comorbidities in 23.0% of patients. In patients with R disease, surgery followed by different adjuvant chemotherapy (CT) regimes was the antineoplastic treatment of choice (64.8%) with efficacy results (OS 37.5 months;95% CI 18.4 - 56.7), in the range of contemporary standards. The common use of neoadjuvant CT for BR disease (94.4%), with surgery in 50% of them, and its results (OS 30.8 months;95% CI 10.5 - 51.2) reflected current controversies of treatment recommendations and evolution in this scenario. Paliative CT with or without radiotherapy was the standard specific treatment in LAU disease (95.1%) with survival results (PFS: 10.8 months;95% CI 8.8 - 12.7. OS: 20.3 months;95% CI 13.5 - 27.2) that justify the distinct character and the specific study of this entity. Conclusion: RWE for localized pancreatic cancer aroused from the analysis of this population confirms the distinct nature of patients assisted in daily practice, as well as mirrors the complexity of decision making in clinical assumptions in which a

Residential end-uses disaggregation and demand response evaluation using integral transforms

引用

Journal of Modern Power Systems and Clean Energy 2017年第1期5卷 91-104页

作者： Antonio GABALDóN Roque MOLINA Alejandro maríN-PARRA Sergio valero-VERDú Carlos áLVAREZ ETS de Ingenierı´a Industrial Universidad Polite´cnica de CartagenaDr.Fleming s/n30202 CartagenaSpain EPS de Elche Universidad Miguel Herna´ndezElcheSpain Institute for Energy Engineering Universidad Polite´cnica de ValenciaValenciaSpain

Demand response is a basic tool used to develop modern power systems and electricity markets. Residential and commercial segments account for 40%–50% of the overall electricity demand. These segments need to overcome major obstacles before they can be included in a demand response portfolio. The objective of this paper is to tackle some of the technical barriers and explain how the potential of enabling technology(smart meters) can be harnessed, to evaluate the potential of customers for demand response(end-uses and their behaviors) and,moreover, to validate customers’ effective response to market prices or system events by means of non-intrusive methods. A tool based on the Hilbert transform is improved herein to identify and characterize the most suitable loads for the aforesaid purpose, whereby important characteristics such as cycling frequency, power level and pulse width are identified. The proposed methodology allows the filtering of aggregated load according to the amplitudes of elemental loads, independently of the frequency of their behaviors that could be altered by internal or external inputs such as weather or demand response. In this way, the assessment and verification of customer response can be improved by solving the problem of load aggregation with the help of integral transforms.

The majority of children with perinatally acquired human immunodeficiency virus (HIV) do not survive beyond childhood but this is changing due to the benefit of antiretroviral therapy for the perinatally infected cohort, so affected children are now approaching the age to be mothers. The aim of this article is to evaluate the outcomes of pregnant women with HIV acquired by vertical transmission in our centre and encourage the results obtained in “Thirty Years Later: Pregnancies in Female Perinatally Infected with Human Immunodeficiency Virus-1”, a review article published in this journal in 2012 [2]. We report 6 patients with eight pregnancies with HIV acquired by vertical transmission. They delivered a total of nine newborns between 2004 and 2013. In any case, mother-to-child transmission was reported. The management of pregnant women with HIV acquired by vertical transmission is complicated, since the patients are the most of the cases young and the compliance to the treatment may be poor. The prematurity was the more frequent complication and the cesarean section was the more frequent form of ending. In our case series, mother-to-child transmission was absent.

World Journal of Cardiology 2012年第1期4卷 8-14页

作者： Pablo Salinas Raúl Moreno Luis Calvo Santiago Jiménez-valero Guillermo Galeote Angel Sánchez-Recalde Teresa López-Fernández Sergio Garcia-Blas Diego Iglesias Luis Riera Isidro Moreno-Gómez Jose mar.a Mesa Ignacio Plaza Rocio Ayala Rosa Gonzalez José-Luis López-Sendón Division of Interventional Cardiology University Hospital La Paz Unit of Echocardiography University Hospital La Paz Department of Cardiology University Hospital La Paz Vascular Surgery University Hospital La Paz Department of Cardiac Anaesthesia University Hospital La Paz Cardiac Surgery University Hospital La Paz Department of Cardiology Hospital Infanta Sofia Department of Cardiology Hospital de la Cruz Roja

AIM: To study a cohort of consecutive patients under-going transcatheter aortic valve implantation (TAVI) and compare the outcomes of atrial fibrillation (AF) patients vs patients in sinus rhythm (SR). METHODS: All consecutive patients undergoing TAVI in our hospital were included. The AF group comprised patients in AF at the time of TAVI or with history of AF, and were compared with the SR group. Procedural, echocardiographic and follow-up variables were compared. Likewise, the CHA 2 DS 2-VASC stroke risk score and HAS-BLED bleeding risk score and antithrombotic treatment at discharge in AF patients were compared with that in SR patients. RESULTS: From a total of 34 patients undergoing TAVI, 17 (50%) were allocated to the AF group, of whom 15 (88%) were under chronic oral anticoagulation. Patients in the AF group were similar to those in the SR group except for a trend (P = 0.07) for a higher logistic EuroSCORE (28% vs 19%), and a higher prevalence of hypertension (82% vs 53%) and chronic renal failure (17% vs 0%). Risk of both stroke and bleeding was high in the AF group (mean CHA 2 DS 2-VASC 4.3, mean HAS-BLED 2.9). In the AF group, treatment at discharge included chronic oral anticoagulation in all except one case, and in association with an antiplatelet drug in 57% of patients. During a mean follow-up of 11 mo (maximum 32), there were only two strokes, none of them during the peri-procedural period: one in the AF group at 30 mo and one in the SR group at 3 mo. There were no statistical differences in procedural success, and clinical outcome (survival at 1 year 81% vs 74% in AF and SR groups, respectively, P = NS). CONCLUSION: Patients in AF undergoing TAVI show a trend to a higher surgical risk. However, in our cohort, patients in AF did not have a higher stroke rate compared to the SR group, and the prognosis was similar in both groups.

Background: This document includes recommendations and guidelines issued by a group of Mexican researchers and specialists gathered in the First National Colloquium for the Diagnosis and Management of Chronic Myeloid Leukaemia (CML) by initiative of Instituto Nacional de Cancerología and with the support of the Leukaemia Department of the MD Anderson Cancer Center. Mexico lacks of updated information taken from its own reality on the diagnosis and treatment of CML and other haematological disorders;besides, there are no national guidelines. Aim: To publish a consensus document with guidelines for the management of CML adjusted to the national environment and overall characteristics. Method: The participants answered a DELPHI questionnaire about the overall aspects of the disease, aiming to target controversial topics, discuss them in the colloquium, and to agree on the best ones. After those meetings, a final document was drawn up. Results: The group presents recommendations for definition, diagnosis, prognosis, monitoring, and treatment of CML in Mexico. Conclusions: Having consensus guidelines for the clinical management of CML in our country will enable the consensual practice of Mexican specialists regarding the clinical approach to CML, as well as optimize the resources which allow the rational planning of the medical care strategies.
