Upon sucrose density gradient fractionation, lipid rafts were recovered mainly in fraction 4, where flotillin-1 was predominantly present. A proportion of BACE1 was recovered in fraction 4, while the majority was present

in high-density nonraft fractions (fraction 8–10) (Fig. 4a). The percentage of BACE1 in the raft fraction was 14% and 3% in sellckchem neurons expressing BACE1-WT and BACE1-CA4, respectively (Fig. 4b), confirming that lipid raft association of BACE1 is dependent on its palmitoylation in primary neurons as well. Figure 4 Lipid raft Inhibitors,research,lifescience,medical distribution of BACE1 depends on palmitoylation in primary rat cerebral cortical Inhibitors,research,lifescience,medical neurons. (a) CHAPS extracts of cultured neurons infected with recombinant adenoviruses expressing BACE1-WT or BACE1-CA4 were fractionated via sucrose density gradient … A proportion of APP was detected in fraction 4, with the majority recovered from nonraft fractions. The percentages of APP in the raft fraction were similar for SH-BACE1-WT- and SH-BACE1-CA4-expressing cells (Fig. 4c), suggesting that raft distribution of BACE1 does not directly affect that of APP. Inhibitors,research,lifescience,medical We additionally evaluated the cellular localization of BACE1 using double immunofluorescence staining. Immunostaining with 1D4 revealed localization

of BACE1 in both soma and neurites. There were no appreciable differences in the staining Inhibitors,research,lifescience,medical patterns between BACE1-WT- and BACE1-CA4 (Fig. 4d). Upon double labeling with 1D4 and anti-flotillin-1, flotillin-1 immunoreactivity was nearly observed as punctate staining that partially overlapped that of 1D4. The extent of the colocalization of 1D4 and flotillin-1 immunoreactivities appeared reduced in Inhibitors,research,lifescience,medical neurons expressing BACE1-CA4, relative to those expressing BACE1-WT (Fig. 4d), consistent with the results of biochemical fractionation. Aβ production is not influenced by raft association of BACE1 in neurons Since lipid rafts appear

to represent an important site for amyloidogenic processing of APP by BACE1 (Cordy et al. 2006; Araki 2010; Rushworth and Hooper 2010; Vetrivel and Thinakaran 2010), AV-951 we analyzed the secretion of Aβ from primary neurons overexpressing BACE1-WT or BACE1-CA4. On Western blots, neurons expressed comparable levels of BACE1-WT and BACE1-CA4 (Fig. 5a). BACE1-WT and BACE1-CA4 enhanced secretion of both Aβ40 and Aβ42 to similar extents (by approximately 80%), compared to control cells infected with empty adenovirus (Fig. 5b and c). Figure 5 Neuronal Aβ production is not influenced by raft association of BACE1. (a–c) Cultured neurons were infected with recombinant adenoviruses expressing BACE1-WT, BACE1-CA4, or empty adenoviruses (mock). (a) Cell lysates were analyzed by Western …

In keeping with this, Bergsland et al. explored the patency in saphenous vein CABG in which the proximal

anastomoses were performed with automatic connector devices or with a traditional suture technique on 46 patients who underwent OPCAB, using one thoracic graft and one or more saphenous vein grafts.6 Grafts were attached to the aorta with a Symmetry connector in 23 patients, and partial occlusion of Inhibitors,research,lifescience,medical the aorta and sutured anastomoses were used in 23 other patients. Angiography was repeated after 3–5 months. Bergsland et al. showed that 1) Intraoperative graft patency did not differ between the two groups; 2) Vein graft patency decreased to 50% in the Symmetry group, whereas it was 90% in the suture group (P = 0.01); and 3) Twenty-five percent of the Symmetry grafts had significant stenosis in the connector. These observations Inhibitors,research,lifescience,medical stressed the fact that saphenous vein grafts anastomosed to the aorta with the Symmetry

proximal connector had low intermediate patency compared with those with traditionally sutured anastomoses. Importantly, the authors discouraged the routine use of this device in coronary artery Inhibitors,research,lifescience,medical bypass operations. Although clinical practice inclined to reject the use of these devices, other studies reported a positive experience with advanced devices; Diegeler et al. compared the patency rate of the saphenous vein coronary bypass grafts in which the proximal anastomoses were performed with second-generation automatic connector devices to the suture Inhibitors,research,lifescience,medical technique.7 This was examined in 86 patients who underwent CABG with at least one vein graft anastomosed to the ascending aorta with the Symmetry G2 connector. Diegeler et al. reported that 1) Eighty patients had at least one connector successfully implanted; 2) Freedom from cardiac mortality,

myocardial infarction, and target vessel reintervention was 72/80 (90%); 3) Six patients underwent a target vessel reintervention on the connector grafts; 4) Six-month Inhibitors,research,lifescience,medical (mean 193 ± 36 days) angiography patency rates for the connector grafts were 72/81 (88.89%), 37/40 (92.5%) in sutured grafts, and 60/62 (96.8%) in arterial grafts. The authors concluded that saphenous vein grafts anastomosed to the aorta with the Symmetry G2 connector had early and mid-term patency rates comparable to the conventional sutured Carfilzomib anastomoses and that these results supported the efficiency of the second generation of symmetry aortic connectors. ROUTINE USE OF INTRAOPERATIVE EPIAORTIC ULTRASOUND somehow atheroma release from the ascending aorta and proximal arch is a key reason for stroke and neurological injury following cardiac surgery.8 The precise discovery of atheroma before aortic manipulation is required to allow surgical strategies to decrease the risk of embolization.

and different structures of the latent factors can be specified,20 can be used to estimate to what extent genetic and environmental risk factors are specific to a given PD or shared in common with other PDs or axis I disorders, and thus to investigate sources of comorbididity.49,50 By including measures of the same phenotypes on different points in time, they can also be used to determine if genetic effects differ over time in a developmental perspective. DSM-IV personality disorders Cluster A PDs have been found to aggregate in families of probands with Inhibitors,research,lifescience,medical schizophrenia (see below). Familial coaggregation has also been found for borderline PD and antisocial PD39 and for borderline PD and all the other cluster B PDs,51 as well as for the DSM-III cluster C PDs.44 A unfortunately population-based Inhibitors,research,lifescience,medical twin study including all PDs within

cluster B indicated that borderline PD and antisocial PD appeared to share genetic risk factors above and beyond those shared in Inhibitors,research,lifescience,medical common with the other cluster B disorders,43 and a twin study of cluster C PDs suggested that genetic factors influencing obsessive-compulsive PD appeared to be relative specific to this disorder.45 Kendler et al, in the only population-based multivariate twin study including all 10 DSM-IV PDs that has been published,52 found that the best-fitting model included three genetic and three environmental factors in addition to disorder-specific factors. The structure of the genetic factors is shown in

Figure 1. The first genetic factor (AC1) had high Tipifarnib myeloid loadings on PDs from all 3 clusters Inhibitors,research,lifescience,medical including paranoid, histrionic, borderline, narcissistic, dependent, and obsessive-compulsive PD. This factor probably reflects a broad vulnerability to PD pathology and/or negative emotionality, and is related to genetic liability to the normal personality trait neuroticism. The second genetic factor (AC2)was quite specific with substantial loadings only on borderline and antisocial PD. This is Inhibitors,research,lifescience,medical consistent with the results from the abovementioned family studies,39 and suggests genetic liability to a broad phenotype for impulsive/aggressive GSK-3 behavior. The third factor identified (AC3) had high loadings only on schizoid and avoidant PD. This can be interpreted in several ways. It might in part reflect genetic risk for schizophrenia spectrum pathology (see below). From the perspective of the five-factor model of normal personality it reflects genetic liability for introversion.53 Finally, it is noteworthy that obsessive-compulsive PD had the highest disorder-specific genetic loading, which parallels prior findings that this PD shares little genetic and environmental liability with the other cluster C PDs.

This method allowed us to determine in which of the two condition

This method allowed us to determine in which of the two selleck catalog conditions the typical frontal negativity pattern of the prestimulus

SME would be observed. This frontal negativity is thought to reflect the involvement of the left inferior prefrontal cortex (LIPC) in episodic encoding and is associated with subsequent memory recognition (Wagner et al. 1998, 1999; Otten et al. 2001). Involvement of the prefrontal cortex Inhibitors,research,lifescience,medical (PFC) in prestimulus effects has been reported in a series of functional magnetic resonance imaging (fMRI) studies showing the crucial role of prefrontal cortex in processing of future events (Sakai and Passingham 2003, 2006; Haynes et al. 2007). In a first study using a task cueing paradigm similar to the one e-book presented in this article, Inhibitors,research,lifescience,medical Sakai and colleagues identified the neural correlates of task sets, showing a pretask activation in the PFC related to the preparation of a specific task. The authors interpreted this

finding associating the activation of the anterior part of the PFC to the construction of higher order representations that are involved in the preparation of future task operations even without specific task items (Sakai and Passingham 2003). In a following study they showed the existence of a mechanism in the PFC that is involved in the representation Inhibitors,research,lifescience,medical of task rules and revealed how this mechanism modulates subsequent cognitive performance through a rule-specific neural activity before the task execution (Sakai and Passingham 2006).

In a third study, they demonstrated the possibility to infer from the activity Inhibitors,research,lifescience,medical of medial and lateral regions of the PFC which of two tasks Inhibitors,research,lifescience,medical the subjects were intending to perform, showing that this area encodes intention-related information specific to the preparation of the future task (Haynes et al. 2007). Besides the involvement of PFC, midbrain and medial temporal regions were shown to play a role in predicting later recollection (Mackiewicz et al. 2006; Park and Rugg 2010). In a direct comparison of the influence of transient and sustained attentional processes on successful encoding, Reynolds et al. (2004) investigated the relation between item and task level processes and reported evidence for an enhanced activation Carfilzomib of the PFC during transient attention. Their results showed greater activation in the LIPC during task switching (task change at every trial) compared to the single task condition (same task throughout a block) and for subsequently remembered versus forgotten items. Further findings showing an increased activation of PFC during transient versus sustained attentional processes can be also found in the task switching research literature (Braver et al. 2003; Gladwin et al. 2006).

Schneider et al10 applied these criteria to a large, state -wide

Schneider et al10 applied these criteria to a large, state -wide selleck compound database in California and excluded all but 10% of patients. The resulting sample was younger, less severely ill, more highly educated, and more likely to be white and with higher incomes than the population as a whole. These sorts of data provide little new guidance to the patient, family, or clinician in the selection of treatment approaches. In fact, there is

a small but growing literature on issues relating to subject selection in clinical trials.11 In schizophrenia, for example, subjects tend to be younger than the general clinical population and are Inhibitors,research,lifescience,medical more likely to be male and part of an ethnic minority.12 In the Treatment Strategies in Schizophrenia (TSS) study, fewer than 10% of those screened were actually enrolled in the study12 The story is much the same in bipolar illness. In general, subjects enrolled in studies tend to have been ill for a very long time – 15 years in bipolar trials13 – and are unstable or unsatisfied Inhibitors,research,lifescience,medical with their current treatment. Even in studies attempting to recruit first-episode

patients, the period of undetected or untreated illness exceeds 3 years.14 Age itself is a common concern, with many studies having Inhibitors,research,lifescience,medical an arbitrary age cutoff of 55 or 60 years. Even “geriatric” studies have been restricted, for all intents and purposes, to the “young-old” population of patients in their sixties. Few older patients have ever been studied,15 despite the clear impact of advanced age on pharmacokinetics, dynamics, and drug metabolism16 and on treatment response.17 Inhibitors,research,lifescience,medical In general, the rigid exclusions of most regulatory-oriented clinical trials have significantly Inhibitors,research,lifescience,medical distorted the conclusions of these studies. Public health model intervention studies Studies that are informed by a public

health model are often, called “effectiveness” studies. We avoid use of that term, since it seems to convey multiple and conflicting meanings in different audiences. Public health studies bring us into the world of actual practice with time-pressured clinicians taking care of large numbers of patients Carfilzomib with uncertain clinical presentations, complex comorbidities, and varying degrees of interference with ideal levels of compliance. The exclusive focus on symptomatology is expanded to include outcomes related to issues of function, disability, morbidity, mortality, resource use, and quality of life. The classic public health trial is used to assess the expected outcome under usual circumstances of practice.18 In contrast to the elegantly crafted efficacy trial, a public health trial must be bigger in size, simpler in design, broader in terms of inclusions and narrower in terms of exclusions, and more representative with respect to settings of care.

We assessed the reliability of paramedic interpretation of the ru

We assessed the reliability of paramedic interpretation of the rule among 155 paramedics by measuring the kappa coefficient for interobserver agreement for each element of the rule. The kappa value for the overall interpretation of the rule was 0.93 (95% CI, 0.87 to 0.99). In addition, agreement for the 8 individual components of the CCR was also very good, with kappa values ranging from 0.66 to 1.00. The paramedics were asked to Inhibitors,research,lifescience,medical indicate on a five-point Likert scale how comfortable they would be

in applying the CCR to this patient. The results were very supportive: Paramedics were “very uncomfortable” or “uncomfortable” applying the Canadian sellekchem c-spine Rule in 9.5% of cases; they were “comfortable” or “very comfortable” in 81.7% of cases. We evaluated the potential impact of the rule on the number of necessary immobilizations. If paramedics were allowed to use the rule, 62.2% (95% CI, 60 Inhibitors,research,lifescience,medical to 64) of recruited patients would have required immobilization compared to the actual immobilization rate of 100%. Rationale for the study We have previously derived (phase I) [75] and validated the CCR in physician (phase Inhibitors,research,lifescience,medical IIa) [70], ED triage nurse (phase IIb) [79] and in paramedic (phase IIc) [77] groups. We currently recently demonstrated successful implementation of

the CCR by physicians in multiple hospitals (phase IIIa) [76], with a decrease in diagnostic imaging use by physicians and no adverse events. An implementation study using ED triage nurses is under way (phase IIIb). While we hope to demonstrate that ED triage nurses can safely remove patient’s cervical immobilization devices, it would be significantly more valuable if we could empower Inhibitors,research,lifescience,medical the paramedics to selectively forego immobilization in the first place, and avoid great discomfort to patients. This is a practice already adopted by a number of U.S. and Canadian EMS services. We now hope to move the

Inhibitors,research,lifescience,medical CCR project forward to the next level (phase IIIc) by carefully preparing paramedics to selectively immobilize the c-spine of very low-risk trauma patients who are alert and stable. Many decision rules in the past have not been widely adopted because of a failure to study implementation issues. We believe that this proposed safety evaluation study is an essential step towards the widespread implementation of the CCR by paramedics across Canada. Carfilzomib If this evaluation study is successful, we can then plan wider dissemination of paramedic clearance in a future effectiveness trial. However, the current proposed study must demonstrate both safety and efficacy before dissemination can occur. Methods/Design Design The proposed study will be a prospective cohort study comprised of a five-month training period followed by six-month run-in (could be shorter if no issues are identified) and 36-month evaluation periods in Ottawa, Canada.

Thus, acute migraine attacks can

Thus, acute migraine attacks can effectively be treated with triptans, highly selective 5-H1B/1D receptor agonists, which act mainly via vasoconstriction of dilated cerebral blood vessels, inhibition of the release of neuropeptides such as substance P, and inhibition of nociceptive neurotransmission. Typical antidepressants, Inhibitors,research,lifescience,medical eg, amitriptyline or fluoxetine,

are also effective in the preventive treatment of migraine, probably via their influence on the neurotransmitter systems. These findings are a hint for possible common pathophysiological mechanisms for migraine and depression, and lead to the question of whether polymorphisms relevant for affective disorders might also be involved

in migraine. Genes of the serotonergic system Among the most frequently investigated candidate genes of the serotonergic pathway is the serotonin transporter (5-HTT), which cleaves the synaptic cleft from neurotransmitters and thus limits the duration of Inhibitors,research,lifescience,medical 5-HT function. Two selleck kinase inhibitor polymorphic sites within the 5-HTT gene are partieularly interesting: one located in the promoter region with a deletion/insertion variation of 44 bp, creating short (S) and long (L) alleles, the 5-HTT-linked promoter region (HTTLPR); and a variable number of tandem repeats (VNTR) polymorphism, located Inhibitors,research,lifescience,medical in the second intron of the gene.18 The presence of the S allele of Inhibitors,research,lifescience,medical the HTTLPR is associated with decreased 5-HT reuptake, which, in turn, results in a longer duration of the serotonergic activity.19

Although the results with psychiatric patients are not conelusive, the polymorphism may be of some importance in anxiety-related personality traits,20 depression,21 and sulcidality 22 However, for migraine sufferers, no association has been found to date for this genetic variant of the 5-HTT.23,24 In contrast, the VNTR polymorphism, whose functional significance remains to Inhibitors,research,lifescience,medical be elucidated, seems to play a role in migraine, as the frequency of the ST12.10 allele was increased.23,24 Moreover, differences were observed between migraine with and without aura, thus being in concordance Cilengitide with the assumption that these forms of the disorder might be etiologically distinct.24 These data support the view that susceptibility to migraine has a genetic component, which may, in some cases, be associated with a locus at or near 5-HTT. Further studies investigated genetic variations in the 5-HT http://www.selleckchem.com/products/Paclitaxel(Taxol).html receptors. Whereas no association was observed for the 5-HT2c subtype,25 a polymorphism in the 5-HT2A receptor gene (a T to C transition at position 102), which has been repeatedly associated with psychiatric disorders and treatment response,26,27 also seems to be relevant in migraine.

EBRT was delivered at our institution for 27 patients and at outs

EBRT was delivered at our institution for 27 patients and at outside institutions for 4 patients. Treatments were designed using high energy photons and either 3-D conformal, multi-field techniques (27 patients) or intensity modulated radiation therapy (4 patients). Treatment fields included both the primary tumor and nodal areas at risk. Techniques used

in our institution have been described in detail in prior publications and will only be summarized (1,6,9,11). The EBRT dose was 45-50.4 Gy in 25-28 fractions (Fx) of 1.8 Gy in 27 patients. A boost field was carried to 54-56 Gy in 28-30 Fx in 2 patients. The EBRT Inhibitors,research,lifescience,medical dose was <45 Gy in 2 patients because of intolerance to the treatment (39.6 Gy/22 Fx; 43.2 Gy/24 Fx). Surgical

resection was feasible in 17 of 31 patients after preop CRT (R0 in 11 patients; R1 in 5; R2 in 1) and the Inhibitors,research,lifescience,medical lesion was unresectable in 14 patients. Whipple resection was performed in 9 patients with primary lesions in the head of pancreas, and the other 8 patients had a distal pancreatectomy with splenectomy for primary lesions in the body of the pancreas. A vascular sleeve resection and reconstruction was selleck chem inhibitor necessary in 2 patients (superior mesenteric vein – 1; left renal vein – 1). IOERT was given as a component of treatment in 28 of 31 patients. IOERT was delivered with a mobile electron accelerator (Mobetron®; Sunnyvale, Ca). The IOERT Inhibitors,research,lifescience,medical dose was based on both the extent of resection and the dose of preop EBRT: R0 resection, 12.5 Gy; R1, median 12.5 Inhibitors,research,lifescience,medical Gy (range, 10-15 Gy); R2, 15 Gy; unresectable 17.5 Gy (n=2) or 20 Gy (n=12). IOERT energy was based on the depth of the tumor bed or unresected tumor, and IOERT applicator size included the tumor bed or unresected tumor Inhibitors,research,lifescience,medical with a 1-cm margin (e.g., 4 cm

tumor/tumor bed =6 cm applicator). Systemic maintenance chemotherapy was preferred in all patients but given in only 16 of 31 (unknown in 3). Maintenance chemotherapy was gemcitabine-based in all patients who received additional therapy. Neoadjuvant chemotherapy was given prior to preop CRT in 7 patients consisting of several cycles of gemcitabine plus nab-paclitaxel. Outcomes Outcomes evaluated include survival [overall Batimastat (OS) and disease-free (DFS)], disease relapse [local failure in the EBRT field (LF), central failure in the IOERT field (CF) and Navitoclax side effects distant metastases (DM)] and treatment tolerance (during preop CRT, the peri-operative period, and the 30-day post-operative period). OS and DFS were calculated with the Kaplan-Meier method (13). Differences between Kaplan-Meier curves were calculated with the log-rank test (univariate analyses). Both survival and time to relapse were calculated from initiation of treatment. Results Patient status was evaluated at time of analysis with median follow-up of 19 months for all patients and 31 months for survivors.

We support the spike processing method for all the algorithms use

We support the spike processing method for all the algorithms used; that is the main claim of this paper: design, development and implementation of a spike-based processing control architecture and to avoid using an external Lenalidomide buy computer for processing, with extremely low power consumption and AER communication.First of all we have to determine the elements to integrate according with the biological principles: image sensor, a hardware architecture where the CNS behavior is emulated and a robot to execute the movements. There are many sorts of problems to deal with in this selection: sensor must be a spiking retina, the architecture has to keep as many CNS features as possible, within only addition, subtraction and injection of spikes, and finally, the robotic platform will be made of motors which mimic the muscles.The first element of the architecture is the image sensor. We have chosen a silicon retina, the dynamic vision sensor developed by the Tobi Delbruck research group [23]. It is a VLSI chip made of 128 �� 128 analog pixel firing spikes (with AER protocol) when a threshold is reached.Applying several processing layers to these events flow [24], a single event, which meets the center of an object, is isolated. Therefore, this event plays the role of the target position for the system, so the retina will deliver the reaching position to the architecture.The main part of the system turns around the VITE algorithm [11]. It was selected because it is inspired by the biological movement and was designed to mimic it. It has been translated into the spikes domain using spike-based building blocks which add, subtract or inject spikes like the human neural system. This algorithm generates a non-planned trajectory and it needs a second algorithm to produce and control the forces applied to the motors which mimic the muscles. In this paper we are focused on the first algorithm and therefore, no feedback is performed. Our aim is to evaluate the viability of translating the VITE completely into the spikes domain and applying it to a real robotic platform in order to enable the second algorithm and to close the control loop.In order to achieve the described goal, we have transformed the algorithm using existing spike processing blocks developed for our research group [21,25,26] and put them into MATLAB Simulink to test and adjust the blocks. Afterwards, two FPGA based boards were used to allocate the blocks and mimic the biological structure (one for the brain and the other one for the spinal cord). The final archite
A micromechanical silicon resonant accelerometer converts the acceleration signals to be tested into the frequency variation of the resonator. Thus, the output is a quasi-digital signal. Moreover, the micromechanical silicon resonant accelerometer has the advantages of a wide dynamic range, strong anti-interference capacity and high stability.

First, there has been no placebo-controlled randomized trial that

First, there has been no placebo-controlled randomized trial that has assessed the effectiveness of anticoagulant therapy in patients with PAH. Available data were derived from small, retrospective,

and single centre studies. Second, available literature is restricted to idiopathic PAH with almost no published evidence for Linsitinib price other types of PAH. Accordingly, the generalizability of survival benefit reported in idiopathic PAH patients to other types of PAH (eg, scleroderma associated PAH) remains controversial. Third, there is lack of data on the added benefit of anticoagulant therapy in patients receiving modern PAH-target therapy. Fourth, little data exist regarding the risk stratification of bleeding in PAH patient receiving anticoagulant therapy. Currently, the European Society of Cardiology and the European Respiratory Society recommend that anticoagulant treatment should be considered in patients with idiopathic PAH, heritable PAH, and PAH due to use of anorexigens (Class IIa), with a lower level of recommendation in patients with associated PAH (Class IIb). 6 The American College of Chest Physicians clinical guidelines support the use of anticoagulation

with a grade “B” recommendation (a moderate recommendation) based on fair level of evidence in idiopathic PAH patients, and weak recommendation based on expert opinion only for other PAH types. 7 Anticoagulation In Pah: Data From Compera Registry The database of the Comparative, Prospective Registry of Newly Initiated Therapies for Pulmonary Hypertension

(COMPERA), 8 was recently analyzed to assess the effect of anticoagulation on the long-term survival in patients with various forms of PAH. COMPERA is an ongoing prospective European pulmonary hypertension registry that began in 2007 with the contribution of 41 pulmonary hypertension centers from 7 European countries. The study analyzed the data of 1283 patients with newly diagnosed PAH based on right heart catheterization. Patients who received anticoagulation at any time during the registry were grouped into the anticoagulation group (n = 738; Batimastat 58%), whereas patients who never received anticoagulation were grouped into the no anticoagulation group (n = 545; 42%). According to type of PAH, anticoagulation was used in 66% of 800 patients with idiopathic PAH, and in 43% of 483 patients with other forms of PAH. Vitamin K antagonists were used in 93% of patients followed by heparins (6%) and new oral anticoagulants (1%). In idiopathic PAH patients, during the 3-year follow-up period, the mortality rate in anticoagulation group was 14.2%, versus 21% in the no anticoagulation group (survival advantage, p = 0.006). This survival benefit occurred despite the fact that patients in the anticoagulation group had worse baseline hemodynamics.
