This case report describes the feasibility and potential benefit of the use of a high-speed rotational atherectomy device (the Rotablator?) in the treatment of renovascular hypertension in a patient with a recorded restenosis of an ostial renal artery lesion following standard balloon angioplasty. 相似文献

Objective
Variants of estrogen receptor α (ERα) have been associated with obesity, dyslipidemia, diabetes and blood pressure. The Middle East registers some of the highest rate of metabolic syndrome worldwide. The aim of this study is to investigate the relationship between metabolic syndrome, a clustered combination of these metabolic factors, and polymorphisms PvuII and XbaI of ERα in Lebanese Caucasian elderly overweight subjects.Material/Methods
250 Caucasian Lebanese unrelated elderly men and women, median age 71 years, were studied. ERα intronic polymorphisms variants, PvuII and XbaI diplotypes and genotypes, were examined. Associations with metabolic syndrome, defined by the American Heart Association/National Heart, Lung, and Blood Institute (AHA/NHLBI), and its components, namely high density lipoprotein (HDL), fasting glucose levels, blood pressure, and waist circumference were evaluated in regression models.Results
ER α diplotypes and genotypes distributions were similar between participants with and without metabolic syndrome, in the overall group of subjects, and by gender. No consistent associations between the diplotypes and genotypes tested and metabolic syndrome, or its components, could be detected.Conclusions
Genetic variants in ERα were not associated with metabolic syndrome or its components, in a group of 250 Lebanese Caucasian elderly participants, a group with a high prevalence of metabolic syndrome. 相似文献5.
Impact of Calcium and Two Doses of Vitamin D on Bone Metabolism in the Elderly: A Randomized Controlled Trial 下载免费PDF全文

The optimal dose of vitamin D to optimize bone metabolism in the elderly is unclear. We tested the hypothesis that vitamin D, at a dose higher than recommended by the Institute of Medicine (IOM), has a beneficial effect on bone remodeling and mass. In this double‐blind trial we randomized 257 overweight elderly subjects to receive 1000 mg of elemental calcium citrate/day, and the daily equivalent of 3750 IU/day or 600 IU/day of vitamin D3 for 1 year. The subjects’ mean age was 71 ± 4 years, body mass index 30 ± 4 kg/m2, 55% were women, and 222 completed the 12‐month follow‐up. Mean serum 25 hydroxyvitamin D (25OHD) was 20 ng/mL, and rose to 26 ng/mL in the low‐dose arm, and 36 ng/mL in the high‐dose arm, at 1 year (p < 0.05). Plasma parathyroid hormone, osteocalcin, and C‐terminal telopeptide (Cross Laps) levels decreased significantly by 20% to 22% in both arms, but there were no differences between the two groups for any variable, at 6 or 12 months, with the exception of serum calcitriol, which was higher in the high‐dose group at 12 months. Bone mineral density (BMD) increased significantly at the total hip and lumbar spine, but not the femoral neck, in both study arms, whereas subtotal body BMD increased in the high‐dose group only, at 1 year. However, there were no significant differences in percent change BMD between the two study arms at any skeletal site. Subjects with serum 25OHD <20 ng/mL and PTH level >76 pg/mL showed a trend for higher BMD increments at all skeletal sites, in the high‐dose group, that reached significance at the hip. Adverse events were comparable in the two study arms. This controlled trial shows little additional benefit in vitamin D supplementation at a dose exceeding the IOM recommendation of 600 IU/day on BMD and bone markers, in overweight elderly individuals. © 2017 American Society for Bone and Mineral Research. 相似文献

Inferior outcome after allogeneic transplant in first remission in high‐risk AML patients who required more than two cycles of induction therapy 下载免费PDF全文

While some patients with high‐risk acute myeloid leukemia (AML) require one or two cycles of induction chemotherapy to achieve a complete remission (CR), others require more than two cycles. We examined the outcomes of patients with high‐risk AML who received allogeneic HPC transplant in CR1. Forty five consecutive high‐risk AML patients in CR1 were included. All 45 patients had adverse cytogenetics, FLT 3 mutations, or secondary AML. Group A patients (n = 33) received one or two cycles, and Group B (n = 12) three or more cycles of induction chemotherapy. The patients were comparable in age, sex, white cell count at presentation, and time from diagnosis and from last chemotherapy to transplant. The 100‐day mortality rate was higher in Group B patients (50% vs. 9%, P = 0.006). They had a higher non‐relapse mortality (33% vs. 6%, P = 0.035) and a longer length of hospital stay from the day of stem cell infusion (median 21 vs. 20, P = 0.02; third quartile 22 vs. 28, P = 0.02). There was also a trend toward inferior event‐free survival and overall survival. High‐risk AML patients undergoing allogeneic transplant in CR1 after three or more cycles of induction chemotherapy have an inferior outcome and higher mortality when compared to those who only needed one or two cycles of induction chemotherapy. Novel strategies are needed to reduce the transplant‐related mortality in high‐risk AML patients needing more than two cycles of induction chemotherapy prior to allogeneic transplant in CR1. Am. J.

The accurate diagnosis of anomalous coronary arteries by invasive angiography is limited by the inability to define the anatomic course in relation to surrounding structures. Computed tomographic coronary angiography has recently emerged as a noninvasive method to visualize the coronary arteries. Multislice computed tomography with up to 64 detector arrays, along with 3-dimensional rendering, has further improved the temporal and spatial resolution of noninvasive coronary imaging. In this series of cases, the investigators describe their institution's experience with computed tomographic coronary angiography as a complement to invasive coronary angiography in determining the origin and course of different anomalous coronary arteries in 16 patients. With the aid of 3-dimensional volume rendering, 6 anomalous right coronary arteries, 4 anomalous left circumflex coronary arteries, 4 single coronary arteries, and 2 anomalous left main coronary arteries were all clearly defined with regard to their origin and course. It is proposed that computed tomographic coronary angiography is the diagnostic test of choice in the evaluation of such anomalies. 相似文献
