Introduction Conclusions References
BACKGROUND Data comparing effects of transient worsening renal function (WRFt) and persistent WRF (WRFp) on outcomes in patients hospitalized with acute heart failure (AHF) are lacking. We determined the characteristics of hospitalized AHF patients who experienced no worsening renal function (non-WRF), WRFt, or WRFp, and the relationship between cohorts and AHF-related outcomes. METHODS AND R...
A polar-optimized version of the fifth-generation Pennsylvania State University–National Center for Atmospheric Research Mesoscale Model (MM5) was developed to fill climate and synoptic needs of the polar science community and to achieve an improved regional performance. To continue the goal of enhanced polar mesoscale modeling, polar optimization should now be applied toward the state-of-the-a...
OBJECTIVES To determine whether venous congestion, rather than impairment of cardiac output, is primarily associated with the development of worsening renal function (WRF) in patients with advanced decompensated heart failure (ADHF). BACKGROUND Reduced cardiac output is traditionally believed to be the main determinant of WRF in patients with ADHF. METHODS A total of 145 consecutive patient...
نتایج حاصل از توسعه یک سامانه پیش بینی همادی برای مدل wrf جهت پیش بینی میدان باد سطحی در محدوده خلیج فارس در تحقیق حاضر ارائه می شود. سامانه مذکور ترکیبی از ایجاد پریشیدگی در شرایط اولیه و استفاده از طرح واره های فیزیکی متفاوت می باشد. برای یافتن پیکربندی(های) مناسب مدل wrf از دیدگاه پارامترسازی های فیزیکی تعداد 14 پیکربندی انتخاب شده و پس از انجام اجراهای مدل برای چندین تاریخ منتخب و انجام اع...
BACKGROUND Worsening renal function (WRF) in the setting of heart failure has been associated with increased mortality. However, it is unclear if this decreased survival is a direct result of the reduction in glomerular filtration rate (GFR) or if the mechanism underlying the deterioration in GFR is driving prognosis. Given that WRF in the setting of angiotensin-converting enzyme inhibitor (ACE...
BACKGROUND Renin-angiotensin aldosterone system (RAAS) inhibitors significantly improve outcome in heart failure (HF) patients with reduced ejection fraction (HFREF), irrespective of the occurrence of worsening renal function (WRF). However, in HF patients with preserved ejection fraction (HFPEF), RAAS inhibitors have not been shown to improve outcome but are still frequently prescribed. METH...
در این پژوهش سیستم جفتشده جدیدی از طرحواره هواویز HAM با مدل میانمقیاس پیشبینی عددی وضع هوا WRF معرفی شده است. در مقایسه با طرحوارههای هواویز بهکاررفته در مدل WRF، طرحواره هواویز HAM از دستاورد جدیدی تحت عنوان روش شبه مدال برای توزیع اندازه ذرات هواویز استفاده میکند. پنج نوع اصلی هواویزهای جهانی شامل سولفات، کربن سیاه، کربن آلی، ذرات گردوغبار و نمک دریا در این مدل در نظر گرفته شدهاند. شب...
We aimed to establish the prevalence and effect of worsening renal function (WRF) on survival among patients with acute decompensated heart failure. Furthermore, we sought to establish a risk score for the prediction of WRF and externally validate the previously established Forman risk score. A total of 657 consecutive patients with acute decompensated heart failure presenting to the emergency ...
OBJECTIVE The objective of the study was to assess urinary biomarkers of renal injury for their individual or collective ability to predict Worsening renal function (WRF) in patients with acutely decompensated heart failure (ADHF). METHODS In a prospective, blinded international study, 87 emergency department (ED) patients with ADHF were evaluated with biomarkers of cardiac stretch (B type na...
