Loeys-Dietz syndrome (LDS) is a rare autosomal-dominant connective tissue disorder caused by heterozygous mutations in the genes encoding transforming growth factor beta receptor 1 or 2 (TGFBR1 or TGFBR2). Although an association between LDS and osteoporosis has been reported, the skeletal phenotype regarding bone mass is not well characterized. Here, we report on two LDS patients with mutations in TGFBR2. Patient 1 was a 24-year-old man who had a total of three fractures involving the left radius, the left metacarpal, and the right femur. At the age of 14 years, lumbar spine areal bone mineral density Z-score was -4.0 and iliac bone histomorphometry showed elevated bone turnover (bone formation rate per bone surface: 91 μm 3/μm 2/year; age-matched control values 37 [10], mean [SD]) and mildly low trabecular bone volume per tissue volume (17.2%; age-matched control values 25.7 [5.3]). Bone mineralization density distribution (BMDD) in trabecular bone was increased (Ca Peak 22.70 wt% Ca; age-matched control values 21.66 [0.52]). Patient 2, a 17-year-old girl, suffered from diffuse bone pain but had not sustained fractures. At 14 years of age, her lumbar spine areal bone mineral density Z-score was -3.4. Iliac bone histomorphometry at that age confirmed low bone mass (bone volume to tissue volume 10.1%, same control values as above) and high bone turnover (bone formation rate per bone surface 70 μm 3/μm 2/year). BMDD in trabecular bone was significantly shifted toward increased mineralization (Ca Peak 22.36 wt% Ca). Thus, it appears that LDS can be associated with low bone mass and high bone turnover but increased matrix mineralization of trabecular bone.

Objective To examine the risk of venous thromboembolism (VTE) associated with exposure to testosterone therapy in middle-aged and older men. Patients and Methods We conducted a case-control study of 30,572 men 40 years and older who were enrolled in one of the nation's largest commercial insurance programs between January 1, 2007, and December 31, 2012. Cases were defined as men who had a primary diagnosis of VTE and received an anticoagulant drug in the 60 days after their diagnoses. Cases were matched with 3 controls on event/index month, age, geographic region, diagnosis of hypogonadism, and diagnosis of any underlying prothrombotic condition. Conditional logistic regression analysis was used to calculate adjusted odds ratios (aORs) and 95% CIs for the risk of VTE associated with previous exposure to testosterone therapy. Results Exposure to testosterone therapy in the 15 days before the event/index date was not associated with an increased risk of VTE (aOR, 0.90; 95% CI, 0.73-1.12). None of the specific routes of administration examined were associated with an increased risk of VTE (topical [aOR, 0.80; 95% CI, 0.61-10.41], transdermal [aOR, 0.91; 95% CI, 0.38-2.16], and intramuscular [aOR, 1.15; 95% CI, 0.80-1.64]). These findings persisted using exposure windows that extended to 30 and 60 days before the event/index date. Conclusion Having filled a prescription for testosterone therapy was not associated with an increased risk of VTE in commercially insured middle-aged and older men. These findings may provide clinically relevant information about the benefit-risk assessment for men with testosterone deficiency considering treatment. © 2015 Mayo Foundation for Medical Education and Research.

Background-The HeartMate II (HMII) destination therapy (DT) trial demonstrated significant improvements in outcomes in continuous-flow left ventricular assist devices compared with patients implanted with the pulsatile-flow HeartMate XVE. The primary hypothesis of the current study is that trial patients enrolled after the initial data cohort would have better clinical outcomes. Methods and Results-Two hundred eighty-one patients who underwent HMII for DT from May 2007 to March 2009 (Mid Trial [MT] group) were compared with the initial 133 HMII patients from March 2005 to May 2007 (Early Trial [ET] group). Patient entry criteria were the same during the 2 time periods. Survival, adverse events, and quality of life were compared between the 2 groups. Baseline characteristics were similar between the groups. Compared with the ET group, patients in the MT group had reduced adverse event rates for bleeding requiring transfusions (1.66 versus 1.13 events per patient-year, P<0.001), sepsis (0.38 versus 0.27, P=0.025), device-related infections (0.47 versus 0.27, P<0.001), and hemorrhagic stroke (0.07 versus 0.03, P=0.01). Other event rates were similar between groups including ischemic stroke (0.06 versus 0.05 events per patient-year, P=0.57). Survival at 1 year in the MT group was 73% versus 68% in the ET group (P=0.21). Additionally, there was a significant reduction in deaths caused by hemorrhagic stroke (P=0.01). Quality of life improvements were significant in both the groups (P<0.001). Conclusions-The benefit of DT therapy with the HMII is confirmed in subsequent trial patients, with improved adverse event rates and a strong trend for improvements in survival.

The practice of nursing has a duty to educate, communicate, and resource patients and families during the period in which the solution to an ethical dilemma is predetermined by evidence-based practice. Clearly, there is a gap in the quality of care provided or the interpretation of the quality of care being provided during difficult ethical situations requiring a systematic change to increase patient and family comfort and satisfaction.

Background: The purpose of this study is to compare liposomal bupivacaine to a modified (Ranawat) local injection for total knee arthroplasty (TKA). Methods: This is a prospective, randomized study of 105 consecutive patients undergoing primary TKA. Group A patients received a periarticular injection with liposomal bupivacaine and group B with a mixture of ropivacaine, epinephrine, ketorolac, and clonidine. There were 54 patients in the group A (liposomal bupivacaine) and 51 in group B. Results: There were no differences in the groups with respect to age, sex, and preoperative knee scores. There were no differences with respect to postoperative narcotic usage and knee range of motion. Conclusion: Liposomal bupivacaine as a periarticular injection after TKA demonstrated similar pain levels, narcotic usage, and range of motion compared to a modified Ranawat suspension but improved walking distance. © 2016 Elsevier Inc..
