| 1 | Beta-blocker therapy in elderly patients with renal dysfunction and heart failure显示文摘OBJECTIVE To assess the role of beta-blockers(BB)in patients with chronic kidney disease(CKD)aged≥75 years.METHODS AND RESULTS From January 2008 to July 2014,we included 390 consecutive patients≥75 years of age with ejection fraction≤35%and glomerular filtration rate(GFR)≤60 m L/min per 1.73 m^2.We analyzed the relationship between treatment with BB and mortality or cardiovascular events.The mean age of our population was 82.6±4.1 years.Mean ejection fraction was 27.9%±6.5%.GFR was 60-45 m L/min per 1.73 m^2 in 50.3%of patients,45-30 m L/min per 1.73 m^2 in 37.4%,and<30 m L/min per 1.73 m^2 in 12.3%.At the conclusion of follow-up,67.4%of patients were receiving BB.The median follow-up was28.04(IR:19.41-36.67)months.During the study period,211 patients(54.1%)died and 257(65.9%)had a major cardiovascular event(death or hospitalization for heart failure).BB use was significantly associated with a reduced risk of death(HR=0.51,95%CI:0.35-0.74;P<0.001).Patients receiving BB consistently showed a reduced risk of death across the different stages of CKD:stage IIIa(GFR=30-45 m L/min per 1.73 m^2;HR=0.47,95%CI:0.26-0.86,P<0.0001),stage IIIb(GFR 30-45 m L/min per 1.73 m^2;HR=0.55,95%CI:0.26-1.06,P=0.007),and stages IV and V(GFR<30 m L/min per 1.73 m~2;HR=0.29,95%CI:0.11-0.76;P=0.047).CONCLUSIONS The use of BB in elderly patients with HFr EF and renal impairment was associated with a better prognosis.Use of BB should be encouraged when possible. | Juan Martínez-Milla Marcelino Cortés García Julia Anna Palfy Mikel Taibo Urquía Marta López Castillo Ana Devesa Arbiol Ana Lucía Rivero Monteagudo María Luisa Martín Mariscal Inés Jiménez-Varas Sem Briongos Figuero Juan Antonio Franco-Pelaéz JoséTuñón | 2021 | Journal of Geriatric Cardiology2021，18，1： | 3 |
| 2 | A Three-Dimensional Range-Free Localization Algorithm Based on Mobile Beacons for Wireless Sensor Networks显示文摘In wireless sensor networks (WSNs) the position information of individual nodes is a matter of vital importance because allows the implementation of necessary network functions such as routing, querying and other applications. The objective of this paper is to propose an algorithm of three-dimensional distributed range-free localization for WSNs, using a mobile beacon (MB) equipped with a rotary and tilting directional antenna. This algorithm, denominated as the three-dimensional azimuthally defined area localization algorithm (3D- ADAL), is executed in each sensor node and is based only on the analysis of the information received from the MB, therefore is energy efficient and contributes to extend the lifetime of the sensor network. Additionally the proposed algorithm has the advantage of being simple and economical. The simulation results show that the proposed algorithm is a practical, effective and accurate method for a three-dimensional location of sensor nodes in a WSN. | GUERRERO E ALVAREZ J RIVERO L | 2010 | Computer Aided Drafting,Design and Manufacturing2010，20，1： | 3 |
| 3 | Successful treatment with hysteroscopy for infertility due to isthmocele and hydrometra secondary to cesarean section: A case report显示文摘BACKGROUND An isthmocele is a scar defect in the uterine wall due to a cesarean section. Its prevalence is unknown,but it has been associated with secondary infertility.Here,we present a case where the patient suffered from an isthmocele that was associated with persistent hydrometra,which developed during in vitro fertilization.CASE SUMMARY The patient underwent hysteroscopic surgery,which successfully resolved the isthmocele as well as the hydrometra. Afterward,two high-quality,euploid embryos,determined by morphological assessment and pre-implantation genetic diagnostic testing,were transferred. This resulted in uterine pregnancy,as determined byserum β-human chorionic gonadotropin levels on day 14(180 m U/mL) and ultrasound-confirmed presence of a gestational sac with a positive embryocardia at week 6. The pregnancy reached 36 wk without any complications,and the product was born in good health. We report a successful isthmocele treatment in a patient with secondary infertility,in which the isthmocele was the cause of persistent hydrometra.CONCLUSION Hydrometra caused by secondary cesarean is an infertility factor,which can be corrected by hysteroscopy plus ablation of the isthmocele. | Luis Pablo López Rivero Miguel Jaimes Felipe Camargo Esther López-Bayghen | 2019 | World Journal of Clinical Cases2019，7，6： | 2 |
