The inhibiting factors most frequently spontaneously reported by

The inhibiting factors most frequently spontaneously reported by the GPs were only very few palliative care patients in their practice during the

course (11x) and not enough time available for the training Selleck NLG-8189 programme (10x). Inhibiting factors reported by the GPTs were that medical elements were lacking in the programme (5x) and Inhibitors,research,lifescience,medical that not all steps in the programme had been addressed (3x). During the 6months duration of the programme the GPTs provided palliative care for an average of two patients (range 0–5). Discussion Main findings We developed the ACA training programme to improve communication between GPs and their palliative care patients, consisting of eight consecutive steps, and based on three key areas of attention in communication: availability of the GP for the patient, current issues that should be raised by the GP, and anticipating various scenarios. The results of this study show that the programme appears to be applicable to practising GPs Inhibitors,research,lifescience,medical who attended a 2-year Palliative Care Peer Group Training Inhibitors,research,lifescience,medical Course and to (inexperienced) GPTs from five vocational training groups. The ACA checklist was appreciated by GPs as useful both in practice and as a learning tool, whereas GPTs mainly appreciated the list for use in practice. A quarter of the GPs

and a third of the Inhibitors,research,lifescience,medical GPTs spontaneously reported the ACA checklist to be a useful guide for communication with palliative care patients. Strengths and limitations of this study Both content and educational approach of the ACA training programme are evidence-based. The content of the ACA training programme is based on the results of recent studies among palliative

care patients, their relatives, GPs, and end-of-life consultants. The educational approach was derived from two systematic Inhibitors,research,lifescience,medical reviews of methods in training programmes for communication in palliative and cancer care. Attendance and appreciation of the training programme were evaluated for each step of the programme. The newly developed training programme was assessed among practising GPs and inexperienced GPTs. The GPs participated Cediranib (AZD2171) in a two-year Palliative Care Peer Group Training Course, and probably had a more than average commitment to palliative care, unlike the GPTs, who participated as part of their vocational training, with no special commitment. This might explain the moderate GPT response rate (67%) and their lower scores for appreciation. The appreciation scores of the two groups can only be compared with caution, because the GPs scored their appreciation on a 10-point scale and the GPTs on a 5-point scale. Non-responding GP(T)s might have had lower attendance rates and lower appreciation scores.

Safety measures to reduce the risk of the infant coming to harm a

Safety measures to reduce the risk of the infant coming to harm at night from suffocation or other breathing problems sometimes associated with sudden

infant death syndrome (SIDS), should also be part of parental education about sleep. Main recommendations22 include the following: Have the baby sleep on his or her back and on a firm mattress that will not obstruct breathing Use a safety-approved cot with narrow gaps between the rails Ensure that the baby’s face cannot be covered during the night Inhibitors,research,lifescience,medical Do not allow the baby to become overheated at night Be sure the bedroom is smoke-free Do not sleep with the baby on a sofa or armchair Avoid cosleeping if either parent has consumed alcohol, or has taken medication or other substances with a sedative affect. Preschool children The nature of the usual Inhibitors,research,lifescience,medical sleep disturbance, and the advice required, is different after infancy into the toddler period and beyond. Many children at this stage of development recurrently resist going to bed at the required time, and/or Inhibitors,research,lifescience,medical wake repeatedly at night, demanding their parents’ attention, including coming into their bed. As at other ages and with other sleep problems, medical factors must be excluded but the usual explanations are behavioral,

especially: Anxiety about separating from parents at night Stimulating activities within the bedroom Inadequate limit-setting on uncooperative bedtime or night-time behavior Inhibitors,research,lifescience,medical Unhelpful associations with being in bed. If parents lose their temper, or threaten or punish the child, he or she will come to associate bedtime with upset and fear Having failed to acquire self-soothing ways of coping with night waking. Behavioral Inhibitors,research,lifescience,medical treatment methods can be very effective in these circumstances (sometimes in a surprisingly short time). Other possible contributory factors with which parents need to be acquainted include: Trametinib purchase Inappropriate patterns of daytime napping, ie, too little or

too much daytime napping no for the child’s age or, alternatively, a nap too near bedtime Putting the child to bed too early while he or she is in the “forbidden zone” of maximal alertness and not yet physiologically capable of sleep. Bedtime should coincide with being “sleepy tired” Night-time fears, which often begin at an early age, can cause difficulty getting off to sleep or disturbance during the night. School-age children Again, the pattern of sleep disorders changes somewhat at this age. Certain causes of sleeplessness in preschool children may still apply, but other causes of sleeping badly may begin to show themselves. Night-time fears23 might intensify and become more complex.

6%) (data not shown). Patients with private insurance had a significantly lower proportion of females (53.7% versus 69.0%) and were more likely to be white (64.8% versus 27.6%) (data not shown). There were no statistical differences between patients under the age of 65 years

who had Medicare (disabled) and those who did not have Medicare (data not shown). Table 1 Demographic, clinical, and socioeconomic characteristics of 249 CRC patients according to p53 status As shown in Table 2, in unadjusted analyses, the odds of having Inhibitors,research,lifescience,medical p53nac for unselleck chemicals employed patients were 0.86 relative to employed patients (95% CI =0.52, 1.43). For patients with Medicaid coverage, the odds of having p53nac were 1.31 times higher than for patients without Medicaid (95% CI, 0.59,

2.91). No association was seen between private insurance coverage and p53nac prevalence (OR 0.94, 95% CI, 0.55, 1.58). Among patients under the age of 65, those with Medicare had 0.81 times the odds of having p53nac compared to patients without Medicare (95% CI, 0.25, 2.64). After Inhibitors,research,lifescience,medical adjustment for age, sex, race and tumor stage, all ORs drew marginally closer to the null, except for the association with unemployment, which moved farther from the null (unadjusted OR 0.86 versus adjusted OR 0.74). Table 2 Odds ratio (OR) and 95% confidence intervals (95% CI) for the crude and adjusted associations between measures of SES and p53 abnormality Discussion Although the unadjusted Inhibitors,research,lifescience,medical and adjusted estimates for the association between the measures of SES with p53nac were not statistically significant, a weak association was detected among Medicaid recipients. Patients of low SES may experience different exposures (e.g., diet, infections, air quality, and other environmental exposures) that lead to abnormal p53. Patients with Inhibitors,research,lifescience,medical Medicaid coverage may be most representative

of low SES patients since Medicaid is typically provided only to low income individuals and families. For patients with Inhibitors,research,lifescience,medical Medicaid coverage, the odds of having p53nac were 1.28 times greater than for patients without Medicaid. This positive association supports our hypothesis that low SES patients have higher odds of p53 abnormalities. The finding, however, was not statistically significant. The other potential measures of SES did not support our hypothesis, but this may be due to limitations in obtaining SES information from medical records. Information on employment was available only in the medical records of individuals, and, since a higher proportion Linifanib (ABT-869) of patients considered unemployed were females and older, these patients may have either had an employed spouse or have been retired and receiving retirement benefits. Therefore, unemployment as measured in this study may not have been a reliable indicator of low SES. For private insurance, actual rates of coverage vary substantially across plans, with variations in both employer and employee premium contributions and in cost-sharing amounts (14).

Automated shimming was

Automated shimming was performed using the in-built standard Siemens algorithms. Data were acquired from 1024 points, FOV (field of view) 300 mm, TR (repetition time)/TE (echo time) 500/2.3 msec, flip angle 40°, bandwidth 4000 Hz, six averages. In order to maintain signal-to-noise ratio (SNR) and to limit scan time, data were acquired using a 13 × 13 × 13 scan acquisition matrix and data were interpolated for analysis to a 16 × 16 × 16 matrix, giving a nominal voxel size of 6.6 cm3 in an acquisition time of 46 min 17 sec. The center of the acquisition grid was positioned at the center of the skull. Data were reconstructed using the Siemens spectroscopy software (Syngo VB13©,

Siemens, Erlangen, Germany), with a single voxel Inhibitors,research,lifescience,medical placed over each hippocampus according to anatomical borders, and summed for each individual. Postprocessing and spectral peak BIX 01294 in vivo fitting were performed using the AMARES Inhibitors,research,lifescience,medical (Vanhamme et al. 1997) algorithm within the jMRUI software package

(Naressi et al. 2001) (Version 2.2). Data were corrected for the effects of saturation using the flip angle and T1 values (2.39 sec for PCr and 0.79 sec for ATP). Results were confirmed by independent blinded data analysis. Although a range of stimulation tasks have been developed to be performed while in an magnetic Inhibitors,research,lifescience,medical resonance imaging (MRI) scanner, these tasks require the subject to be able to see a projection screen by using MR-compatible mirrors placed over the coils. The design and dimensions of the spectroscopy head coil precluded placement of these mirrors and hence it was not possible to perform these tasks during spectroscopy. To stimulate continued Inhibitors,research,lifescience,medical cognitive activity during the spectroscopy acquisition, the

delayed recall parts of the verbal recall tasks were performed during Inhibitors,research,lifescience,medical the scan. These tasks were performed at the beginning of the CSI acquisition in order to minimize noise in the acquisition from the muscle movements during speech. Statistical analysis for significance was performed using the two-tailed Student’s t-test for paired samples with significance taken at P < 0.05. The baseline PCr/ATP ratio prior to intervention was averaged for each subject and this averaged too value was used as their baseline PCr/ATP ratio for comparison with PCr/ATP ratios after both lipid infusion and NA. Results Eight subjects underwent studies with cognitive activity, but one subject was only able to complete the lipid infusion arm of the cognitive activity studies. Subject characteristics at baseline (Table 1) were the same for those undergoing cognitive testing and those undergoing only resting studies (four subjects). Table 1 Subject characteristics Blood tests For all subjects, baseline fasting insulin, glucose, FFA, and β-hydroxybutyrate were normal (Table 2). The lipid infusion elevated FFA levels from 0.3 ± 0.2 mmol/L at baseline to 1.3 ± 0.3 mmol/L after 3 h and 1.2 ± 0.4 mmol/L after 4 h. During the noninfusion arm, circulating FFA levels decreased.

Usually, these assumptions do not hold in practice but, strikingl

Usually, these assumptions do not hold in practice but, strikingly, in most, studies this fact is entirely ignored. In our studies we rely therefore on nonparametric alternatives17,35 (Figure 2d): Wilcoxon’s rank sum test is based on the ranks of the replicates rather than on the actual signal values. This test (and other tests based on linear rank statistics such as the van der Waerden test) is preferable to the parametric

t- tests if the distributional assumptions cannot be proven to be Gaussian. PF-562271 clinical trial Furthermore, for “noisy” data this test, yields more robust results since it. is less sensitive against outlier Inhibitors,research,lifescience,medical values. For larger sample sizes, ie, >25 replicates, we can Inhibitors,research,lifescience,medical approximate the P value of the Wilcoxon rank test by the standard normal distribution. However, most practical applications will be based on a rather smaller number of observations (sample sizes in the order of 4 to 12). Therefore, those P values must, be calculated exactly This can be done using a recursive method.36

If several different experimental Inhibitors,research,lifescience,medical conditions are screened (for example different, time points after medical treatment), then each gene expresses a certain numerical profile across these conditions. Clustering algorithms are explorative statistical methods that group together genes with similar profiles and separate genes with dissimilar profiles, whereby similarity (or dissimilarity) is defined numerically by a pairwise (dis)similarity function such as Euclidean distance or Pearson correlation.37-40 Inhibitors,research,lifescience,medical Hierarchical clustering can be combined with a colorcoded representation of the signal values (the expression patterns) and visualized in the form of a dendrogram. Clustering is a very intuitive way of visualizing data, but it. should be pointed out that, the dendrogram is strongly dependent, on the parameters chosen for cluster analysis. Inhibitors,research,lifescience,medical Thus, each clustering process should undergo decent validation.41 Associated groups of genes42 are usually further investigated, for example for common binding sites in the promoter

sequences of the genes or for common functional content.43 The major result, of the explorative analysis is essentially a. list of potential marker genes relevant, for the disease or treatment under analysis. Since microarray data is errorprone, this list contains a lot, of false positives. Thus, further filtering to steps are commonly included in the analysis. Recent, methods therefore aim at, the correlation of the gene expression profiles with complementing sources of data such as pathway annotation, gene ontology (GO) categories, sequence analysis, clinical data, etc.44-46 Genes do not. act as individual units; they collaborate in overlapping pathways, the deregulation of which is a hallmark for the disease under study New bioinformatics tools have been developed that judge gene expression changes in the context of such pathway analysis.

After 2-h adhesion, the plating medium was carefully aspirated a

After 2-h adhesion, the plating medium was carefully aspirated and myelination medium was slowly added into the wells (700 μl each well for a 12 well plate). The cover slips were firmly pushed down to the bottom of culture wells with a pipette tip. We initially tried either N2 or NBM (with B27 supplement) as the myelination medium, but only limited amount of myelination was observed. However, with Inhibitors,research,lifescience,medical the combination of N2 and NBM (1:1) yielded robust myelination in the spinal cord derived culture. For the first week of culture, NGF (50 ng/mL)

and NT-3 (10 ng/mL) were included in the medium. The medium was changed every three days by replacing two-third of the medium with fresh medium. The day of the primary culture is defined as day 1 in vitro (DIV1). At DIV10, insulin was excluded from N2 and the ratio of the insulin-free N2 to NBM was Cytoskeletal Signaling inhibitor adjusted to 4:1 to prevent cell overgrowth. The final concentrations of Inhibitors,research,lifescience,medical individual component in N2 medium (DMEM-F12 based, high glucose, Invitrogen) are listed as following: insulin (10 μg/mL), transferrin (50 μg/mL), sodium selenite (5.2 ng/mL), hydrocortisone (18 ng/mL), putrescine (16 μg/mL), progesterone (6.3 ng/mL), biotin (10 ng/mL), N-acetyl-L-cysteine Inhibitors,research,lifescience,medical (5 μg/mL), BSA (0.1%),

and penicillin–streptomycin (50 units/mL). The procedures for cortex-derived culture are rather similar to those Inhibitors,research,lifescience,medical described from the spinal cord. After removing the meninges and other connective tissue, the entire cerebral cortex from both hemispheres was dissected out and pooled together from six embryos. Typically, total number of dissociated cells from the cortex is much higher (~10-fold) than from the spinal cord. Under such preparation, T3 was introduced Inhibitors,research,lifescience,medical to the

myelination medium at DIV10. Immunocytochemistry The cultured cells were rinsed with ice-cold PBS and fixed with 4% paraformaldehyde (PFA) for 15 min at room temperature (RT). Following washing in PBS, cells were permeabilized with 0.5% Triton X-100 for 20 min, and blocked with a solution containing 10% normal goat serum/1% BSA and 0.1% Triton X-100 for 1 h. Cells were then incubated in the primary antibodies diluted in PBS/10% serum overnight. After washing, cells were incubated with biotin- or fluorescein-labeled second antibodies (mouse or rabbit IgG conjugated with Alex 488/555) ADP ribosylation factor for 1 h at RT, followed by incubation with avidin fluorescein (Alex 488 or 555) in PBS for 30 min. Cover slips were then washed and air dried, and viewed under a fluorescence microscope (Oly-750 from Olympus, Pittsburgh, PA, USA) with proper filters. For immunostaining of O4, primary antibody was applied before fixation. DAPI (1.5 μg/mL) was used in the mounting medium to counterstain the nuclei. Images were captured with a CCD camera, and superimposed using the Adobe Photoshop (version 7.


The lack of dystrophin and the destruction


The lack of dystrophin and the destruction of the DGC leads to a delocalization of the nitric oxide sinthase in myofibers (nNOS). This is believed to have a great MEK inhibitor impact in contracting muscles, where the proper formation of NO triggers vasodilatation and increases blood flow. Then a functional ischemia can be recurrent in dystrophin-less muscles and can strongly contribute to myofiber damage for hypoxia-reperfusion injury as well as metabolic distress. According to this view, drugs able Inhibitors,research,lifescience,medical to mimic NO action, either by enhancing its formation (L-arginine, NOdonors) or supporting its downstream signalling, exerts positive effect in mdx mice. The restoration of NO signalling also has additional advantages in increasing utrophin expression and in stimulating myogenic program, since follistatin is also under the control of NO (60, 61). Phosphodiesterase (PDE) inhibitors able to enhance the level of cyclic nucleotides also act through similar mechanisms, since NO signals via cGMP. Inhibitors Inhibitors,research,lifescience,medical of PDE5, other than ameliorating heart function in mdx mice, have also been shown to enhance exercise Inhibitors,research,lifescience,medical performance, that has been ascribed to an enhanced vasodilatation (62, 63). These

potential beneficial effect at muscle level should also be considered in DMD patients undergoing trials with sildenafil. Similar results have been obtained in our laboratories by the use of pentoxifylline, an aspecific inhibitor of phosphodiesterase. The action of this Inhibitors,research,lifescience,medical drug is likely the result of both the increase

in cGMP and cAMP, exerting then a wide action on many different parameters. In fact we found the ability of this drug to enhance exercise resistance and regeneration signs, as expected by a NO-like signalling, meanwhile reducing calcium influx and markers of oxidative stress and inflammation, likely via enhanced cAMP (10, 29). A trial with pentoxifylline in DMD patients was little successful due to relevant side effects of this aspecific drug. Stabilization of sarcolemma Inhibitors,research,lifescience,medical has also been attempted in the mdx mouse model. The use of aspecific compounds, such as poloxamer P188, or molecules able to enhance binding to and expression of integrins, such as laminin 111, although promising, raised concerns in relation to Calpain possible deregulation of the extracellular matrix and the unclear outcome in terms of fibrosis and muscle stiffness (64-66). Blocks of channels involved in calcium entry can be another reasonable approach; however the molecular identity of these channels, necessary to develop specific modulators, is still unclear. Mechanosenstive channels or various members of the TRP channel family, such as TRPC1 or TRPV2, have been indicated as possible candidates but a real evidence is still lacking (10, 67-68). Taurine, a safe aminoacid, has an interesting wide action in dystrophic muscle.

The most important is the TH1 response by which proinflammatory m

The most important is the TH1 response by which proinflammatory mediators such as transforming growth factor beta (TGF-β) and tumor necrosis factors gamma (TNF-γ) are secreted. The Pim inhibitor latter activates matrix methyl proteinases, which degrade the matrix, eventually culminating in destruction of enterocyte villi, characteristic of CD. The TH2 pathway will stimulate the B cells to produce specific immunoglobulins including anti-gliadin and anti-tTG antibodies.1 We have demonstrated elevated prostaglandin

E2 and thromboxane B2 levels in the mucosa obtained from CD patients as compared with controls.10 Moreover, we have reported increased Inhibitors,research,lifescience,medical apoptosis in CD patients while on a gluten-containing diet, in comparison

Inhibitors,research,lifescience,medical to controls.11 CLINICAL PRESENTATION The clinical presentation of CD has shifted during the previous decades from the classical presentation in which the toddler suffers from diarrhea, constipation, vomiting, failure to thrive (FTT), abdominal distension, etc., to the child with a monosymptomatic presentation, such as anemia, bone disorders, and arthritis, as well as an Inhibitors,research,lifescience,medical enlarged list of extra-intestinal disorders (Table 1).12 Table 1 Whom to screen? DIAGNOSIS Who should be considered for screening for CD? Many diagnoses of CD are currently being performed following screening tests of first-degree relatives of CD patients; most of them are asymptomatic, others are diagnosed due to related disorders. The diagnosis of CD is being established by symptoms consistent with CD, positive serology, i.e. high anti-tTG, endomysial antibodies Inhibitors,research,lifescience,medical (EMA), and elevated deamidated gliadin peptide antibodies (DGP), encompassing IgG as well as IgA antibodies. As IgA deficiency is much more common in CD compared to the general population, the Inhibitors,research,lifescience,medical tTG and EMA, both belonging to the IgA immunoglobulin family, may be (false) negative in CD. Moreover, in young children, less than 2 years old, the incidence of false negative celiac serology is higher than later in life and should be taken into consideration while evaluating a

child with suspected CD. After demonstrating elevated celiac serology, the ultimate diagnosis should be made upon histological evaluation of the small bowel mucosa. The classical histopathologic findings are: villous atrophy, hyperplastic crypts, increased intraepithelial lymphocytes (IEL) infiltration (CD8), and increased and inflammatory cells infiltration in the lamina propria, as well as increased mitotic index. Many experts are using Marsh histological criteria, in which stage 1 is just IEL infiltration and stage 3c shows total villous atrophy. One should always anticipate the desired improvement of the patient while on a strict gluten-free diet (GFD). Recently, new modified guidelines for the diagnosis of CD have been published in the Journal of Pediatric Gastroenterology and Nutrition.

On top of the overall alpha value, the value for each of the 20

On top of the overall alpha value, the value for each of the 20 items was also high (Table 4). Table 4 Reliability analysis of the 20 patient satisfaction measurement items among patients at emergency departments in Gondar University Referral Hospital, Selleck PFT�� Northwest Ethiopia, May 2012 The overall satisfaction using the mean score indicated that 498 (51.7%) 95%CI: (48.4% – 54.9%) were satisfied with the service, Inhibitors,research,lifescience,medical the providers and the facility suitability whereas 465(48.3%) 95%CI:

(45.1%- 51.6%) were dissatisfied. Assessing the clients’ satisfaction for each item, 36.3% of the clients were dissatisfied or indifferent to the courtesy of staff in the registration area while 63.7% were either satisfied or very satisfied. In about two-thirds (64.2%) of clients, the information provided about medication was not satisfying and ranked fair or below. The degree to which the care providers Inhibitors,research,lifescience,medical talked to the patient using words which the patients could understand was high at 74.2% (Table 5). Table 5 Levels of satisfaction based on 20 measurement items among patients visiting emergency departments in Gondar University Referral Hospital, Northwest Ethiopia, Inhibitors,research,lifescience,medical May 2012 Determinants of patient satisfaction on emergency medical care In the multiple logistic regression analysis using backward stepwise method, the OPD site visited was

significantly associated with level of satisfaction (p<0.0001). Individuals who visited OPD 2 were 1.6 times more likely to be satisfied with the service as compared to those served at OPD 5 (AOR=1.6, 95%CI:1.1, 2.4). Patients who visited OPD 3 were 3.4 times more likely to be satisfied with the emergency service when compared to those visiting OPD 5 (AOR=3.4, 95%CI: 2.1, 5.8). The

Inhibitors,research,lifescience,medical visiting days also had an effect on satisfaction of patient with emergency care provided (p<0.05). Inhibitors,research,lifescience,medical Patients who arrived on Monday were less likely to be satisfied when compared to those visiting on Sundays, even though this turned out to be non-statistically significant in the final model. Patients who came to OPD on Thursday (AOR=1.7, 95%CI: 1.1, 3.0) and Friday (AOR=1.9, 95%CI: 1.1, 3.4) were more likely to be satisfied when compared to their counterparts arriving on Sunday. The medical condition on arrival was a predictor for patient satisfaction at the emergency department (p<0.0001). Patients who were very sick on clinical assessment on their arrival were 3.6 times more likely to be satisfied when compared to those first with good conditions (AOR=3.6, 95%CI:2.3, 5.5) on arrival and patients with moderate condition were 1.6 times more likely to be satisfied with the service (AOR=1.6, 95%CI:1.1, 2.5). Patients very confident with the service provided were nearly twice more likely to be satisfied with emergency service (AOR=1.9, 95%CI: 1.1, 3.1). Another vital determinant of patient satisfaction was perception of being discriminated against by health care providers.

Jneid et al 1 recommended the use of prasugrel as an alternative

Jneid et al.1 recommended the use of prasugrel as an alternative to clopidogrel in ACS patients undergoing percutaneous coronary intervention (PCI), cautioned against its use in those with a history of stroke or

transient ischemic attack because of observed net clinical harm (as shown previously3), and recommended its empiric discontinuation at least 7 days before planned CABG (Table 1). It is important to note that TRITON-TIMI 38 enrolled Inhibitors,research,lifescience,medical ACS patients scheduled to undergo PCI, of whom 74% had non-ST-elevation ACS, and did not enroll medically-treated ACS patients. In addition, prasugrel was compared with a 300-mg loading dose of clopidogrel followed by 75-mg daily maintenance, which was the antiplatelet regimen used in the CURE study.4-6 This regimen, Inhibitors,research,lifescience,medical which achieves a slower platelet inhibition compared with a 600-mg loading dose, was recently shown to be inferior to the double-dosing

regimen examined in the CURRENT-OASIS 7 trial.7 Post hoc analyses from TRITON-TIMI 382 identified two additional subMM102 groups in whom prasugrel had no net Inhibitors,research,lifescience,medical favorable clinical benefit: patients ≥75 years of age and those <60 kg of weight. Table 1 Summary of important recommendations in the 2012 ACCF/AHA focused updates of the UA/NSTEMI guidelines. Ticagrelor Ticagrelor, a nonthienopyridine P2Y12 inhibitor therapy, is a reversible agent that was shown to be superior to clopidogrel in reducing ischemic events in the Inhibitors,research,lifescience,medical PLATO trial.8 PLATO was a landmark trial that included 18,624 medically and invasively treated ACS patients, roughly 60% of whom had non-ST-elevation ACS.8 Using a double-blind, double-dummy design, PLATO compared ticagrelor (180-mg loading dose followed by 90 mg twice daily) with clopidogrel (300- to 600-mg loading dose followed by 75 mg daily). The primary efficacy endpoint was the time to first occurrence of the composite of vascular death, MI, or stroke. At 12 months, ticagrelor was associated Inhibitors,research,lifescience,medical with a 16% relative reduction in the primary composite outcome compared with clopidogrel, which was driven by lower rates of MI and

vascular death. The benefits of ticagrelor appeared consistent across most no subgroups. Importantly, ticagrelor was associated with a remarkable 1.4% absolute risk reduction in all-cause mortality (4.5% versus 5.9%; HR: 0.78; 95% CI: 0.69–0.89), and with significantly lower rates of definite stent thrombosis. There were no significant differences between the ticagrelor and clopidogrel groups in the rates of PLATO major bleeding (the primary safety endpoint), TIMI major bleeding, or fatal bleeding. However, ticagrelor was associated with a higher rate of non-CABG-related major bleeding and caused a higher incidence of dyspnea (not necessitating drug discontinuation except in a few cases) and a higher rate of ventricular pauses ≥3 seconds in the first week.
