Early molecular and cytogenetic response is predictive for long-term progression-free and overall survival in chronic myeloid leukemia (CML)

In the face of competing first-line treatment options for CML, early prediction of prognosis on imatinib is desirable to assure favorable survival or otherwise consider the use of a second-generation tyrosine kinase inhibitor (TKI). A total of 1303 newly diagnosed imatinib-treated patients (pts) were investigated to correlate molecular and cytogenetic response at 3 and 6 months with progression-free and overall survival (PFS, OS). The persistence of BCR-ABL transcript levels >10% according to the international scale (BCR-ABL(IS)) at 3 months separated a high-risk group (28% of pts; 5-year OS: 87%) from a group with >1-10% BCR-ABL(IS) (41% of pts; 5-year OS: 94%; P=0.012) and from a group with 1% BCR-ABL(IS) (31% of pts; 5-year OS: 97%; P=0.004). Cytogenetics identified high-risk pts by >35% Philadelphia chromosome-positive metaphases (Ph+, 27% of pts; 5-year OS: 87%) compared with 35% Ph+ (73% of pts; 5-year OS: 95%; P=0.036). At 6 months, >1% BCR-ABL(IS) (37% of pts; 5-year OS: 89%) was associated with inferior survival compared with 1% (63% of pts; 5-year OS: 97%; P<0.001) and correspondingly >0% Ph+ (34% of pts; 5-year OS: 91%) compared with 0% Ph+ (66% of pts; 5-year OS: 97%; P=0.015). Treatment optimization is recommended for pts missing these landmarks.

LFA-1 expression in a series of colorectal adenocarcinomas

LFA-1 is an adhesion molecule which belongs to the β2-integrin family. Overexpression of LFA-1 in hepatic natural killer cells has been associated with increased apoptosis of neoplastic cells in colorectal cancer (CRC); moreover, studies in CRC have linked LFA-1 overexpression in neoplastic cells with vascular intrusion through adhesion to endothelial cells, thus implying a possible role in creation of metastases.

TAFI and PAI-1 levels in human sepsis

BACKGROUND: Plasminogen activator inhibitor type-1 (PAI-1) is considered to be the main inhibitor of fibrinolysis in sepsis. However, the contribution of TAFI to the inhibition of fibrinolysis in sepsis is currently unknown. METHODS: TAFI antigen and PAI-1 levels were measured in severe sepsis (n = 32) and septic shock (n = 8) patients. In addition, TAFI antigen levels had been determined in 151 controls. RESULTS: Septic patients had significantly (p < 0.0001) decreased TAFI levels (median: 78.9% [range: 32.4-172.6]) as compared to controls (108.1% [35.9-255.4]). TAFI levels were equal in septic shock and severe sepsis (68.9% [32.4-172.6] vs. 82.5% [32.7-144.9], p = 0.987) as well as in survivors and non-survivors (87.1% [32.7-172.6] vs. 65.8% [32.4-129.5], p = 0.166). PAI-1 levels were significantly (705.5 ng/ml [131-5788]) higher in septic shock as in severe sepsis patients (316.5 ng/ml [53-1311], p = 0.016) and were equal in survivors and non-survivors (342 ng/ml [53-1311] vs. 413 ng/ml [55-5788], p = 0.231). TAT/PAP ratio (R((TAT/PAP))) reflecting the dysbalance between coagulation and fibrinolysis was calculated. R((TAT/PAP)) significantly increased with fatality and was significantly dependent on PAI-1, but not on TAFI. PAI-1 levels (570.5 ng/ml [135-5788]) and R((TAT/PAP)) (1.6 [0.3-6.1]) were significantly (p = 0.008 and p = 0.047) higher in patients with overt DIC as compared to patients without overt DIC (310 ng/ml [53-1128] and 0.6 [0.1-4.3]), whereas no difference was found for TAFI levels (68.9% [32.7-133.2] vs. 86.4% [32.4-172.6], p = 0.325). CONCLUSIONS: Although inhibition in sepsis is mediated by both, PAI-1 might be involved early in the sepsis process, whereas TAFI might be responsible for ongoing fibrinolysis inhibition in later stages of sepsis.

Fetal haemoglobin levels in adult type 1 (insulin-dependent) diabetic patients

Glycated haemoglobin levels (HbA1 and HbA1c) are established parameters of long-term glycaemic control in diabetic patients. Depending on the method used, fetal haemoglobin interferes with the assays for glycated haemoglobin. If present in high amounts, fetal haemoglobin may lead to overestimation of glycated haemoglobin levels, and therefore, of average blood glucose concentration in diabetic patients. Glycated (HbA1c) and fetal haemoglobin levels were measured by high pressure liquid chromatography in 60 (30 female) adult Type 1 (insulin-dependent) diabetic patients of Swiss descent, and were compared with levels obtained from 60 normal, non-diabetic control subjects matched for age and sex. Fetal haemoglobin levels were significantly higher in the diabetic patients (0.6 +/- 0.1%, mean +/- SEM; range: 0-3.6%) than in the control subjects (0.4 +/- 0.1%, p < 0.001). Elevated fetal haemoglobin levels (> or = 0.6%) were found in 23 of 60 diabetic patients (38%) compared to 9 of 60 control subjects (15%; chi 2 = 8.35, p < 0.01). In addition, fetal haemoglobin levels in diabetic patients are weakly correlated with glycated haemoglobin (HbA1c) (r = 0.38, p < 0.01). Fetal haemoglobin results were confirmed with the alkali denaturation procedure, and by immunocytochemistry using a polyclonal rabbit anti-fetal haemoglobin antibody. A significant proportion of adult patients with Type 1 diabetes has elevated fetal haemoglobin levels. In certain patients this may lead to a substantial over-estimation of glycated haemoglobin levels, and consequently of estimated, average blood glucose levels. The reason for this increased prevalence of elevated fetal haemoglobin remains unclear, but it may be associated with poor glycaemic control.

Effects of cognitive behavioral stress management on HIV-1 RNA, CD4 cell counts and psychosocial parameters of HIV-infected persons

OBJECTIVE: To determine the effects of cognitive-behavioral stress management (CBSM) training on clinical and psychosocial markers in HIV-infected persons. METHODS: A randomized controlled trial in four HIV outpatient clinics of 104 HIV-infected persons taking combination antiretroviral therapy (cART), measuring HIV-1 surrogate markers, adherence to therapy and well-being 12 months after 12 group sessions of 2 h CBSM training. RESULTS: Intent-to-treat analyses showed no effects on HIV-1 surrogate markers in the CBSM group compared with the control group: HIV-1 RNA < 50 copies/ml in 81.1% [95% confidence interval (CI), 68.0-90.6] and 74.5% (95% CI, 60.4-85.7), respectively (P = 0.34), and mean CD4 cell change from baseline of 53.0 cells/microl (95% CI, 4.1-101.8) and 15.5 cells/microl (95% CI, -34.3 to 65.4), respectively (P = 0.29). Self-reported adherence to therapy did not differ between groups at baseline (P = 0.53) or at 12 month's post-intervention (P = 0.47). Significant benefits of CBSM over no intervention were observed in mean change of quality of life scores: physical health 2.9 (95% CI, 0.7-5.1) and -0.2 (95% CI, -2.1 to 1.8), respectively (P = 0.05); mental health 4.8 (95% CI, 1.8-7.3) and -0.5 (95% CI, -3.3 to 2.2) (P = 0.02); anxiety -2.1 (95% CI, -3.6 to -1.0) and 0.3 (95% CI, -0.7 to 1.4), respectively (P = 0.002); and depression -2.1 (95% CI, -3.2 to -0.9) and 0.02 (95% CI, -1.0 to 1.1), respectively (P = 0.001). Alleviation of depression and anxiety symptoms were most pronounced among participants with high psychological distress at baseline. CONCLUSION: CBSM training of HIV-infected persons taking on cART does not improve clinical outcome but has lasting effects on quality of life and psychological well-being.

European experience with the second-generation Edwards SAPIEN XT transcatheter heart valve in patients with severe aortic stenosis: 1-year outcomes from the SOURCE XT Registry

OBJECTIVES The SOURCE XT Registry (Edwards SAPIEN XT Aortic Bioprosthesis Multi-Region Outcome Registry) assessed the use and clinical outcomes with the SAPIEN XT (Edwards Lifesciences, Irvine, California) valve in the real-world setting. BACKGROUND Transcatheter aortic valve replacement is an established treatment for high-risk/inoperable patients with severe aortic stenosis. The SAPIEN XT is a balloon-expandable valve with enhanced features allowing delivery via a lower profile sheath. METHODS The SOURCE XT Registry is a prospective, multicenter, post-approval study. Data from 2,688 patients at 99 sites were analyzed. The main outcome measures were all-cause mortality, stroke, major vascular complications, bleeding, and pacemaker implantations at 30-days and 1 year post-procedure. RESULTS The mean age was 81.4 ± 6.6 years, 42.3% were male, and the mean logistic EuroSCORE (European System for Cardiac Operative Risk Evaluation) was 20.4 ± 12.4%. Patients had a high burden of coronary disease (44.2%), diabetes (29.4%), renal insufficiency (28.9%), atrial fibrillation (25.6%), and peripheral vascular disease (21.2%). Survival was 93.7% at 30 days and 80.6% at 1 year. At 30-day follow-up, the stroke rate was 3.6%, the rate of major vascular complications was 6.5%, the rate of life-threatening bleeding was 5.5%, the rate of new pacemakers was 9.5%, and the rate of moderate/severe paravalvular leak was 5.5%. Multivariable analysis identified nontransfemoral approach (hazard ratio [HR]: 1.84; p < 0.0001), renal insufficiency (HR: 1.53; p < 0.0001), liver disease (HR: 1.67; p = 0.0453), moderate/severe tricuspid regurgitation (HR: 1.47; p = 0.0019), porcelain aorta (HR: 1.47; p = 0.0352), and atrial fibrillation (HR: 1.41; p = 0.0014), with the highest HRs for 1-year mortality. Major vascular complications and major/life-threatening bleeding were the most frequently seen complications associated with a significant increase in 1-year mortality. CONCLUSIONS The SOURCE XT Registry demonstrated appropriate use of the SAPIEN XT THV in the first year post-commercialization in Europe. The safety profile is sustained, and clinical benefits have been established in the real-world setting. (SOURCE XT Registry; NCT01238497).

A novel mechanism for regulation of calmodulin signaling by RC3

RC3, also known as neurogranin, is a small neuronal IQ domain protein whose only known function is to bind calmodulin (CaM). The hypothesis tested in this work was that RC3 alters the dynamics of the interaction of Ca 2+-CaM with CaM-kinase II, so that there is less CaM-kinase II activation for a given Ca2+ stimulus. To evaluate this hypothesis, we investigated the affinity and kinetics of the interactions of CaM with Ca 2+, RC3 and CaM-kinase II. We quantitated the interaction of the four CaM-kinase II isoforms with CaM and found that the KD for binding of CaM to CaM-kinase II ranged from 7 nM to 60 nM. Using stopped-flow fluorimetry, we determined the kinetics of the interaction of Ca2+-CaM with αCaM-kinase II, and found that the association rate constant is 2.1 × 10 M −1s−1 and the dissociation rate constant is 1.6 s−1. We investigated the effects of RC3 and αCaM-kinase II on the affinity of CaM for Ca2+ and found that both proteins alter the rate of dissociation of Ca2+ from CaM. RC3 increases the rate of dissociation of Ca2+ from the C-terminal binding sites of CaM from 9 s−1 to ∼500 s−1 , while αCaM-kinase II causes a decrease in the rate of dissociation from all four Ca2+ binding sites. Measurement of the rate of dissociation of Ca2+ from CaM in the presence of both RC3 and αCaM-kinase II revealed a role for RC3 in accelerating the dissociation of the Ca 2+-CaM-αCaM-kinase II complex at the end of a Ca2+ signal. We characterized the interaction of RC3 with apo-CaM and Ca 2+-CaM and found that the KD for both of these interactions is about 1 μM. We also directly tested whether RC3 slowed the dynamics of the binding of CaM to αCaM-kinase II and found that RC3 had no effect for large changes in Ca2+, and a modest effect for small changes in Ca2+ levels. Our overall conclusion is that the ability of RC3 to alter the interaction of Ca2+ with CaM allows RC3 to alter the dynamics of interaction of CaM with Ca2+-dependent targets such as CaM-kinase II. ^

The Role of Raf Kinase Inhibitor Protein in Cell Motility

Raf Kinase Inhibitor Protein (RKIP) has been identified as a phosphatidylethanolamine-binding protein capable of inhibiting Raf-1 kinase, an enzyme significant in cell proliferation and cancer development. When properly functioning, RKIP can mediate the expression of Raf-1 kinase and help prevent uncontrolled cell division. RKIP also has suggested, but unclear, roles in spindle fiber formation during mitosis, regulation of apoptosis, and cell motility. The Fenteany laboratory in the Chemistry Department identified a new small molecule, named Locostatin, as a cell migration inhibitor in mammalian cells, with RKIP as its primary molecular target. Dictyostelium discoideum possess two RKIP proteins, RKIP-A and RKIP-B. In order to begin to study the function of RKIP in D. discoideum and its role in cell motility, I created a mutant cell line which lacks a functional RKIP-A gene. In this paper, we show that removal of RKIP-A does not affect vegetative motility, but impairs chemotaxis and development in the presence of drug. Interestingly, RKIP-A knockout mutants appear more resistant to drug effects on vegetative motility than wild-type cells. More research is needed to reconcile these seemingly contrasting results, and to better develop a model for RKIP-A’s role in cell motility.

The Austrian Glacier Inventories GI 1 (1969), GI 2 (1998), GI 3 (2006), and GI LIA in ArcGIS (shapefile) format

Glacier inventories provide the basis for further studies on mass balance and volume change, relevant for local hydrological issues as well as for global calculation of sea level rise. In this study, a new Austrian glacier inventory has been compiled, updating data from 1969 (GI 1) and 1998 (GI 2) based on high-resolution lidar digital elevation models (DEMs) and orthophotos dating from 2004 to 2012 (GI 3). To expand the time series of digital glacier inventories in the past, the glacier outlines of the Little Ice Age maximum state (LIA) have been digitalized based on the lidar DEM and orthophotos. The resulting glacier area for GI 3 of 415.11 ± 11.18 km**2 is 44% of the LIA area. The annual relative area losses are 0.3%/yr for the ~119-year period GI LIA to GI 1 with one period with major glacier advances in the 1920s. From GI 1 to GI 2 (29 years, one advance period of variable length in the 1980s) glacier area decreased by 0.6% yr?1 and from GI 2 to GI 3 (10 years, no advance period) by 1.2%/yr. Regional variability of the annual relative area loss is highest in the latest period, ranging from 0.3 to 6.19%/yr. The mean glacier size decreased from 0.69 km**2 (GI 1) to 0.46 km**2 (GI 3), with 47% of the glaciers being smaller than 0.1 km**2 in GI 3 (22%).

Temperature and salinity reconstruction for sediment core GeoB3313-1

We reconstructed changes of temperature, salinity, and productivity within the southern Peru-Chile Current during the last 8000 years from a high-resolution sediment core recovered at 41°S using alkenones, isotope ratios of planktic foraminifera, biogenic opal, and organic carbon. Paleotemperatures and paleosalinities reached maximum values at ~5500 years ago and thereafter declined to modern values, whereas paleoproductivity continuously increased throughout the last 8000 years. We ascribe these long-term Holocene trends primarily to latitudinal shifts of the Antarctic Circumpolar Current (ACC). The concurrence with shifts in the position of the Southern Westerlies points to a common response of atmospheric and oceanographic circulation patterns off southern Chile. Millennial- to centennial-scale fluctuations of paleotemperatures and paleosalinities, on the other hand, lag displacements in the position of the Southern Westerlies but reveal a significant correlation to short-term temperature changes in Antarctica, indicating a high-latitude control of the ACC at these timescales.
