Abstract

The aftermath of severe COVID-19 frequently involves considerable cardiopulmonary damage, necessitating rehabilitation. This study aimed to evaluate the impact of COVID-19 on cardiopulmonary health and assess the effectiveness of various rehabilitative interventions. Conducted between September 2021 and September 2022, this prospective study included patients who had been diagnosed with severe COVID-19 and admitted at the “Victor Babes” Infectious Diseases and Pulmonology Hospital, Timisoara, Romania. The patients were stratified into low- and high-intensity rehabilitation groups. The rehabilitation protocols were individually tailored, and the patient recovery was closely monitored over a 3-month period. Our cohort comprised 84 patients, with a mean age of 56.3 years for the low-intensity group (n = 42) and 53.1 years for the high-intensity group (n = 42). Both groups showed significant improvements in the lung injury area, need for oxygen supplementation, ejection fraction, systolic pulmonary artery pressure, and forced vital capacity. Additionally, considerable enhancements were observed in maximal voluntary ventilation, FEV1, FEV1/FVC ratio, peak expiratory flow, and forced expiratory flow at 25–75%. The work intensity also demonstrated substantial improvements from the initial testing to the 3-month mark in both groups. This study provides evidence that personalized, targeted rehabilitation strategies can improve long-term cardiopulmonary health in patients recovering from severe COVID-19, proving both low-intensity and high-intensity training as sufficient to improve heart and lung function if performed correctly and over a relatively short duration of 3 months. The study findings underscore the importance of implementing comprehensive cardiopulmonary rehabilitation protocols in the care of post-COVID-19 patients and highlight the value of stratified rehabilitation intensity based on individual patient dynamics and recovery features.

Abstract

Background and Aims: Recent studies have brought evidence on the connection between excess weight and suboptimal glycemic control for Diabetes Mellitus (DM) patients. The aim of this study was to evaluate the association between increased Body Mass Index (BMI) and the likelihood of having suboptimal glycemic control in patients with Type 1 and Type 2 Diabetes Mellitus. Materials and Methods: A case-control study was conducted on 662 patients suffering from Diabetes Mellitus and statistical analysis was performed in order obtain evidence associating BMI and poor glycaemic control. We defined as increased BMI, values >25 kg/m2 and a hemoglobin A1c (HbA1c) value >7% reflected suboptimal glycemic control. Results: 559 (84%) patients had HbA1c >7%. 550 (83 %) patients had a BMI >25 kg/m2. In case of HbA1c >7%, a BMI >25 kg/m2 was found in a number of 457 patients (82 %), whereas a normal BMI was present in 102 (18%) patients. For the HbA1c25 kg/m2 was 93 (90%) and a normal BMI was present in 10 (10%) patients. BMI >25 kg/m2 was not associated with a higher probability of having above-target HbA1c values compared to patients with target HbA1c (OR 0.48, 95% CI: 0.24 to 0.95), with a statistically significant p 25 kg/m2 was significantly higher than the number of patients with a BMI < 25 kg/m2, a BMI above target was not associated with greater odds of having HbA1c higher than the standard 7% level, compared to individuals with normal HbA1c levels. The results emphasize that a multitude of factors are involved in the process of achieving a targeted glycemic control and a stepped-care approach should be considered for optimum management of Diabetes Mellitus.

Abstract

AIMS: The purpose of the Euro Heart Survey Programme of the European Society of Cardiology is to evaluate to which extent clinical practice endorses existing guidelines as well as to identify differences in population profiles, patient management, and outcome across Europe. The current survey focuses on the invasive diagnosis and treatment of patients with established coronary artery disease (CAD). METHODS AND RESULTS: Between November 2001 and March 2002, 7769 consecutive patients undergoing invasive evaluation at 130 hospitals (31 countries) were screened for the presence of one or more coronary stenosis >50% in diameter. Patient demographics and comorbidity, clinical presentation, invasive parameters, treatment options, and procedural techniques were prospectively entered in an electronic database (550 variables+29 per diseased coronary segment). Major adverse cardiac events (MACE) were evaluated at 30 days and 1 year. Out of 5619 patients with angiographically proven coronary stenosis (72% of screened population), 53% presented with stable angina while ST elevation myocardial infarction (STEMI) was the indication for coronary angiography in 16% and non-ST segment elevation myocardial infarction or unstable angina in 30%. Only medical therapy was continued in 21%, whereas mechanical revascularization was performed in the remainder [percutaneous coronary intervention (PCI) in 58% and coronary artery bypass grafting (CABG) in 21%]. Patients referred for PCI were younger, were more active, had a lower risk profile, and had less comorbid conditions. CABG was performed mostly in patients with left main lesions (21%), two- (25%), or three-vessel disease (67%) with 4.1 diseased segments, on average. Single-vessel PCI was performed in 82% of patients with either single- (45%), two- (33%), or three-vessel disease (21%). Stents were used in 75% of attempted lesions, with a large variation between sites. Direct PCI for STEMI was performed in 410 cases, representing 7% of the entire workload in the participating catheterization laboratories. Time delay was within 90 min in 76% of direct PCI cases. In keeping with the recommendations of practice guidelines, the survey identified under-use of adjunctive medication (GP IIb/IIIa receptor blockers, statins, and angiotensin-converting enzyme-inhibitors). Mortality rates at 30 days and 1 year were low in all subgroups. MACE primarily consisted of repeat PCI (12%). CONCLUSION: The current Euro Heart Survey on coronary revascularization was performed in the era of bare metal stenting and provides a global European picture of the invasive approach to patients with CAD. These data will serve as a benchmark for the future evaluation of the impact of drug-eluting stents on the practice of interventional cardiology and bypass surgery.

Abstract

Using PET, we measured the whole-body distribution of 11C-(+)-PHNO (11C-(+)-4-propyl-9-hydroxynaphthoxazine), a D2/3 agonist, as a function of time in adult subjects in order to determine the internal radiation dose. Methods: PET whole-body data were acquired after the injection of 11C-(+)-PHNO (∼360 MBq) in 6 healthy subjects (3 male and 3 female). The PET acquisition duration was a maximum of 112.5 min, and 9 discrete time frames were obtained. After reconstruction of the emission data, 6 organs were identified in the images as exhibiting uptake above background levels. Regions of interest were delineated on these organs, and time–activity curves were generated. The time–activity curve data were corrected for the injected activity, specific organ density, and volume, from which normalized accumulated activities (previously known as residence times) were calculated. The normalized accumulated activities were then used with the software code OLINDA/EXM 1.1 to calculate the internal doses for the standard adult male and female models. Results: The mean effective dose was estimated to be 4.5 ± 0.3 μSv/MBq when all subjects were included and the male model was applied for the dosimetry calculation, and the mean effective dose was estimated to be 5.2 ± 0.2 μSv/MBq when the females were considered separately and the female model was applied for the calculation. The organ receiving the highest dose was the liver (17.9 ± 3.9 μSv/MBq), followed by the kidneys (14.3 ± 3.6 μSv/MBq) and the urinary bladder wall (13.5 ± 3.7 μSv/MBq). Conclusion: The estimated radiation doses for 11C-(+)-PHNO are similar to those reported for other radiotracers labeled with 11C. 11C-(+)-PHNO may be used for multiple PET scans in the same subject and remain within regulatory guidelines.

Abstract

We measured the whole-body distribution of IV-injected [11C]GSK215083, a new 5-HT6 antagonist PET tracer, as a function of time in adult subjects, in order to determine the radiation exposure. After injection with a single bolus of [11C]GSK215083 (range 330–367 MBq; mean 346 MBq), PET emission data were acquired for approximately 120 min in six subjects (three males and three females). Five organs were identified as exhibiting uptake above background. For these, regions of interest were delineated on emission images, and time–activity curves (TAC) generated. Residence times were calculated as the area under the curve of the TAC, normalized to injected activities and standard values of organ volumes. Dosimetry calculations were then performed using the computer program OLINDA/EXM 1.0. The mean effective dose averaged over both males and females (±standard deviation) was estimated to be 7.7 ± 1.0 μSv/MBq (male 7.0 ± 0.4; female 8.5 ± 0.6). For the effective dose equivalent, the corresponding values are 7.8 ± 1.2 μSv/MBq (male 6.8 ± 0.5; female 8.9 ± 0.1). The organ receiving the highest dose was the lung, with an average equivalent dose of 25.6 ± 6.9 μSv/MBq (male 20.8 ± 5.6; female 30.4 ± 4.4). The estimated radiation dose for [11C]GSK215083 is consistent with those for other neuroreceptor ligands labeled with carbon-11. The somewhat higher dose estimate for females compared to males may reflect the difference in observed residence times and representative differences in the male and female phantoms used for dosimetry calculations.

Abstract

This article describes the kinetic modeling of [18F]-FEPPA binding to translocator protein 18 kDa in the human brain using high-resolution research tomograph (HRRT) positron emission tomography. Positron emission tomography scans were performed in 12 healthy volunteers for 180 minutes. A two-tissue compartment model (2-CM) provided, with no exception, better fits to the data than a one-tissue model. Estimates of total distribution volume ( VT), specific distribution volume ( VS), and binding potential ( BPND) demonstrated very good identifiability (based on coefficient of variation ( COV)) for all the regions of interest (ROIs) in the gray matter ( COV VT < 7%, COV VS < 8%, COV BPND < 11%). Reduction of the length of the scan to 2 hours is feasible as VS and VT showed only a small bias (6% and 7.5%, respectively). Monte Carlo simulations showed that, even under conditions of a 500% increase in specific binding, the identifiability of VT and VS was still very good with COVT values obtained from an unconstrained 2-CM with data from a 2-hour scan support the use of VT as an appropriate and feasible outcome measure for [18F]-FEPPA.

Abstract

The D(2) receptors exist in either the high‐ or low‐affinity state with respect to agonists, and while agonists bind preferentially to the high‐affinity state, antagonists do not distinguish between the two states. [(11)C]‐(+)‐PHNO is a PET D(2) agonist radioligand and therefore provides a preferential measure of the D(2) (high) receptors. In contrast, [(11)C]raclopride is an antagonist radioligand and thus binds with equal affinity to the D(2) high‐ and low‐affinity states. The aim was to compare the brain uptake, distribution and binding characteristics between [(11)C]‐(+)‐PHNO and [(11)C]raclopride in volunteers using a within‐subject design. Both radioligands accumulated in brain areas rich in D(2)/D(3)‐receptors. However, [(11)C]‐(+)‐PHNO showed preferential uptake in the ventral striatum and globus pallidus, while [(11)C]raclopride showed preferential uptake in the dorsal striatum. Mean binding potentials were higher in the putamen (4.3 vs. 2.8) and caudate (3.4 vs 2.1) for [(11)C]raclopride, equal in the ventral‐striatum (3.4 vs. 3.3), and higher in the globus pallidus for [(11)C]‐(+)‐PHNO (1.8 vs. 3.3). Moreover [(11)C]‐(+)‐PHNO kinetics in the globus pallidus showed a slower washout than other regions. One explanation for the preferential binding of [(11)C]‐(+)‐PHNO in the globus pallidus and ventral‐striatum could be the presence of a greater proportion of high‐ vs. low‐affinity receptors in these areas. Alternatively, the observed distribution could also be explained by a preferential binding of D(3)‐over‐D(2) with [(11)C]‐(+)‐PHNO. This differential binding of agonist vs. antagonist radioligand, especially in the critically important region of the limbic striatum/pallidum, offers new avenues to investigate the role of the dopamine system in health and disease.

Abstract

The present study focuses on the application of a therapeutic strategy in patients with chronic severe lower limb ischaemia using a plasmid vector encoding the vascular endothelial growth factor (phVEGF165). It has been shown that VEGF promotes neo-vascularization and blood vessel network formation and thus might have the ability to improve blood-flow at the level of the affected limbs. However, little information is available regarding the necessary level of expression of VEGF and its possible related adverse effects. We have subcloned VEGF 165 isoform into pCMV-Script expression vector (Stratagene) under the control of the CMV promoter. Three patients with chronic ischaemia of the lower limb, considered as not suitable for surgical re-vascularization, received intramuscular injection with 0.5 ml saline solution containing 1011 copies of VEGF 165 plasmid. The clinical evolution has been monitored by angiography and estimated by walking time on the rolling carpet (Gardner protocol). Two months after therapy, all three patients showed complete relief of rest pain, improvement of ischaemic ulcer lesions and increased walking distance on the rolling carpet most probably due to appearance of newly formed collateral vessels.

Abstract

Predicting rewards and avoiding aversive conditions is essential for survival. Recent studies using computational models of reward prediction implicate the ventral striatum in appetitive rewards. Whether the same system mediates an organism's response to aversive conditions is unclear. We examined the question using fMRI blood oxygen level‐dependent measurements while healthy volunteers were conditioned using appetitive and aversive stimuli. The temporal difference learning algorithm was used to estimate reward prediction error. Activations in the ventral striatum were robustly correlated with prediction error, regardless of the valence of the stimuli, suggesting that the ventral striatum processes salience prediction error. In contrast, the orbitofrontal cortex and anterior insula coded for the differential valence of appetitive/aversive stimuli. Given its location at the interface of limbic and motor regions, the ventral striatum may be critical in learning about motivationally salient stimuli, regardless of valence, and using that information to bias selection of actions.

Abstract

1993 Objectives To determine by a national survey: 1) the frequency of detection by public screening facilities of radioactivity in patients (pts) who had been treated with 131I for differentiated thyroid cancer (DTC), 2) the types and frequency of the various public facilities where pts were detected, and 3) the management of these pts by the security personnel. Methods Data were tabulated from a Thyroid Cancer Survivors Association, Inc. (ThyCa) website survey from November 2013 to December 2013 and was emailed to ~30,000 associates of ThyCa. Answers were tabulated of respondents (rpds) who reported that s/he 1) was >18 yo, 2) had at least one tx of 131I, and 3) was responding for his/her last 131I tx. The study was approved by the IRB. Results Of 334 rpds, 6.9% (23) attempted to pass through a public facility security checkpoint. Of these 23 pts all were detected and the detections occurred in an airport (7), border crossing (7), government building (3), shopping mall (3), train station (2), and steel recycling plant (1). The security personnel questioned 19 rpds, released 14 rpds without change in travel plans, rescanned 9 rpds, released 1 rpd with change in travel plans, and denied passage in 1 rpd. Security personnel verified the rpd’s 131I tx by examining an official document from the treating physician that was provided by 14 rpds, calling the treating facility regarding 3 rspds, and operating radiation detectors to identify the type and source of radiation in 2 rspds. Security personnel did not verify 131I tx in 4 rspds. Conclusions Public detection of radioactivity after 131I tx is infrequent, occurring in only 6.9% of respondents. Although airports and border crossings accounted for 61% of the sites of detection, the number of detected respondents was very low, and further respondents of the survey continue to be collected.

Abstract

Objective: Self-perceived health status may be helpful in identifying patients at high risk for adverse outcomes. The Euro Heart Survey on Coronary Revascularization (EHS-CR) provided an opportunity to explore whether impaired health status was a predictor of 1-year mortality in patients with coronary artery disease (CAD) undergoing angiographic procedures. Methods: Data from the EHS-CR that included 5619 patients from 31 member countries of the European Society of Cardiology were used. Inclusion criteria for the current study were completion of a self-report measure of health status, the EuroQol Questionnaire (EQ-5D) at discharge and information on 1-year follow-up, resulting in a study population of 3786 patients. Results: The 1-year mortality was 3.2% (n = 120). Survivors reported fewer problems on the five dimensions of the EQ-5D as compared with non-survivors. A broad range of potential confounders were adjusted for, which reached a p

Abstract

Aims: Revascularization in patients with coronary artery disease changed over the last two decades, favouring the number of patients treated by means of percutaneous coronary interventions (PCI) when compared with coronary artery bypass grafting (CABG). Many randomized controlled trials (RCTs) have been performed to compare these two competing revascularization techniques. Because of the strict enrolment criteria of RCTs in which highly selected patients are recruited, the applicability of the results may be limited in clinical practice. The current study evaluates to what extent patients in clinical practice were similar to those who participated in RCTs comparing PCI with CABG. Methods and results: Clinical characteristics and 1-year outcome of 4713 patients enrolled in the Euro Heart Survey on Coronary Revascularization were compared with 8647 patients who participated in 14 major RCTs, comparing PCI with CABG. In addition, we analysed which proportion of survey patients would have disqualified for trial participation (n = 3033, 64%), aiming at identifying differences between trial-eligible and trial-ineligible survey patients. In general, important differences were observed between trial participants and survey patients. Patients in clinical practice were older, more often had comorbid conditions, single-vessel disease, and left main stem stenosis when compared with trial participants. Almost identical differences were observed between trial-eligible and trial-ineligible survey patients. In clinical practice, PCI was the treatment of choice, even in patients who were trial-ineligible (46% PCI, 26% CABG, 28% medical). PCI remained the preferred treatment option in patients with multi-vessel disease (57% in trial-eligible and 40% in trial-ineligible patients, respectively, P < 0.001); yet, the risk profile of patients treated by PCI was better than that for patients treated either by CABG or by medical therapy. In the RCTs, there was no mortality difference between PCI and CABG. In clinical practice, however, we observed 1-year unadjusted survival benefit for PCI vs. CABG (2.9 vs. 5.4%, P < 0.001). Survival benefit was only observed in trial-ineligible patients (3.3 vs. 6.2%, P < 0.001). Conclusion: Many patients in clinical practice were not represented in RCTs. Moreover, only 36% of these patients were considered eligible for participating in a trial comparing PCI with CABG. We demonstrated that RCTs included younger patients with a better cardiovascular risk profile when compared with patients in everyday clinical practice. This study highlights the disparity between patients in clinical practice and patients in whom the studies that provide the evidence for treatment guidelines are performed. © The European Society of Cardiology 2006.

Abstract

[(18)F]-FEPPA is a translocator protein (18 kDa, TSPO) positron emission tomography (PET) radiotracer. Radiation dosimetry was estimated from the whole body biodistribution, taking into consideration TSPO rs6971 (Ala147Thr) polymorphism.[(18)F]-FEPPA whole body PET scans were acquired for six healthy subjects. Time-activity curves were generated from regions of interest of nine organs, from which normalized accumulated activities were calculated and thus internal dose, using OLINDA/EXM 1.1. Genotyping of rs6971, associated with high- and low-affinity [(18)F]-FEPPA binding (high-affinity binder (HAB) and low-affinity binder (LAB)), was performed.Five subjects exhibited the C/C (HAB) allele, and the other carried the minor allele T/T (LAB). The LAB whole body biodistribution showed highest radioactivity accumulation in bladder, whereas in HABs, the spleen received the highest dose. The effective dose of the single LAB (16.3 μSv/MBq) was 23 % less than the mean of the HABs (21.0 ± 2.9 μSv/MBq). When including all subjects, the effective dose was 20.2 ± 3.0 μSv/MBq.[(18)F]-FEPPA radiation dose is consistent with other (18)F-labeled radioligands and the Ala147Thr genotype agreed with [(18)F]-FEPPA distribution.

Abstract

Although they were for a while “dissociated” (Spiegel, 2006) from the clinical and scientific arena, dissociative disorders have in the last several years received a renewed interest among several groups of researchers, who embarked on the work of identifying and describing their underlying neural correlates. Dissociative disorders are characterized by transient or chronic failures or disruptions of integration of otherwise integrated functions of consciousness, memory, perception, identity or emotion. The DSM-IV-TR (2000) includes nowadays under the heading of dissociative disorders several diagnostic entities, such as dissociative amnesia and fugue, depersonalization disorder, dissociative identity disorder and dissociative disorder not otherwise specified (such as Ganser syndrome). In contrast to DSM-IV-TR, ICD-10 (1992) also comprises under the category of dissociative (conversion) disorder the entity of conversion disorder (with its various forms), which is in DSM-IV-TR (2000) captured under the heading of somatoform disorders (and probably will remain under the same heading in the upcoming DSM-V).

Abstract

Left ventricular (LV) free wall rupture is a potentially lethal mechanical complication after myocardial infarction (MI). Pericardial adhesions or slow extracardiac leak and pericardial inflammation may result in a contained cardiac rupture. LV pseudoaneurysm is a relatively uncommon clinical entity. It may occur after MI, but also as a complication of infective endocarditis, cardiac surgery, or trauma. Patients developing LV pseudoaneurysm after MI may present angina pectoris or signs of congestive heart failure (HF) but often are asymptomatic. Surgery is the treatment of choice for LV pseudoaneurysms diagnosed in the first months after MI. The management of chronic LV pseudoaneurysms is still subject of debate. This report highlights a 65-year-old patient newly hospitalized for acute decompensated HF who was diagnosed with a large chronic LV pseudoaneurysm and severe mitral regurgitation. The patient underwent successful resection of the pseudoaneurysm and patch repair of the ruptured ventricular wall.

Abstract

OBJECTIVE: The pharmacokinetic and pharmacodynamic profile of the immediate-release (IR) formulation of quetiapine is characterized by a rapid peak in plasma level and striatal dopamine D(2) receptor occupancy, followed by a rapid decrease to baseline levels, necessitating the use of twice-daily dosing. An extended-release (XR) formulation of quetiapine is currently being developed to achieve similar efficacy using a once-daily dosing regimen. We compared the central D(2) receptor binding between the IR and XR formulations. METHOD: In this open-label, crossover positron emission tomography study using [(11)C]-raclopride, we compared the central D(2) receptor binding potential at expected peak and trough plasma levels using equivalent daily doses of the IR and XR formulations (300, 600, and 800 mg/day) in 12 subjects. Data were collected from April 2002 to May 2003. RESULTS: The mean plasma level of quetiapine at trough was significantly lower than that at peak for all dose groups of both formulations except for IR 300 and 800 mg (all p values < .05), while the mean plasma level did not differ significantly between formulations at trough and peak. The mean occupancy at peak was significantly higher than that at trough for all dose groups other than IR 800 mg/day (all p values < .05) and did not differ significantly between formulations at trough and peak. CONCLUSION: Once-daily dosing of the XR formulation gives peak and trough plasma levels and central D(2) receptor occupancy comparable to twice-daily dosing of the IR formulation. These data should be considered while determining equivalent doses, as well as switching strategies.

Abstract

Imaging the competition between D(2/3) radioligands and endogenous dopamine is so far the only way to measure dopamine release in the living human brain. The dopamine D(2) receptor exists in a high (D(2)(high)) and a low-affinity state for dopamine. Under physiological conditions, dopamine is expected to bind to D(2)(high) only. [(11)C]-(+)-4-propyl-9-hydroxynaphthoxazine ((+)-PHNO) is the first D(2/3) agonist radioligand for positron emission tomography (PET) imaging in humans. Since [(11)C]-(+)-PHNO is expected to bind preferentially to D(2)(high), it should be particularly vulnerable to competition with endogenous dopamine. Nine healthy subjects participated in two PET scans, one after administration of d-amphetamine and one after placebo. [(11)C]-(+)-PHNO PET test re-test variability was determined in 11 healthy subjects. Binding potentials (BPs) were calculated for caudate, putamen, ventral striatum, and globus pallidus. d-Amphetamine led to a significant decrease of [(11)C]-(+)-PHNO BPs in caudate (-13.2%), putamen (-20.8%), and ventral striatum (-24.9%), but not in globus pallidus (-6.5%). d-Amphetamine-induced displacement correlated with serum d-amphetamine levels in all regions but caudate. This is the first report on competition between endogenous dopamine and a D(2/3) agonist radioligand in humans. [(11)C]-(+)-PHNO PET might be a superior measure for release of endogenous dopamine than PET employing conventional D(2/3) antagonist radioligands.

Abstract

Blockade of dopamine D2 receptors remains a common feature of all antipsychotics. It has been hypothesized that the extrastriatal (cortical, thalamic) dopamine D2 receptors may be more critical to antipsychotic response than the striatal dopamine D2 receptors. This is the first double-blind controlled study to examine the relationship between striatal and extrastriatal D2 occupancy and clinical effects. Fourteen patients with recent onset psychosis were assigned to low or high doses of risperidone (1 mg vs 4 mg/day) or olanzapine (2.5 mg vs 15 mg/day) in order to achieve a broad range of D2 occupancy levels across subjects. Clinical response, side effects, striatal ([11C]-raclopride-positron emission tomography (PET)), and extrastriatal ([11C]-FLB 457-PET) D2 receptors were evaluated after treatment. The measured D2 occupancies ranged from 50 to 92% in striatal and 4 to 95% in the different extrastriatal (frontal, temporal, thalamic) regions. Striatal and extrastriatal occupancies were correlated with dose, drug plasma levels, and with each other. Striatal D2 occupancy predicted response in positive psychotic symptoms (r=0.62, p=0.01), but not for negative symptoms (r=0.2, p=0.5). Extrastriatal D2 occupancy did not predict response in positive or negative symptoms. The two subjects who experienced motor side effects had the highest striatal occupancies in the cohort. Striatal D2 blockade predicted antipsychotic response better than frontal, temporal, and thalamic occupancy. These results, when combined with the preclinical data implicating the mesolimbic striatum in antipsychotic response, suggest that dopamine D2 blockade within specific regions of the striatum may be most critical for ameliorating psychosis in schizophrenia., peer-reviewed

Abstract

Background The prediction error (PE) hypothesized by the temporal difference model has been shown to correlate with the phasic activity of dopamine neurons during reward learning and the blood-oxygen level dependent (BOLD) response during reward and aversive conditioning tasks. We hypothesized that dopamine would modulate the PE related signal in aversive conditioning and that haloperidol would reduce PE related activity, while an acute dose of amphetamine would increase PE related activity in the ventral striatum. Methods Healthy participants took an acute dose of amphetamine, haloperidol, or placebo. We used functional magnetic resonance imaging (fMRI) to measure the BOLD signal while they carried out an aversive conditioning task, using cutaneous electrical stimulation as the unconditioned stimulus (US) and yellow and blue circles as conditioned stimulus (CS+ and CS−, respectively). Results Prediction error related BOLD activity was seen only in the ventral striatum in the placebo subjects. The subjects given amphetamine showed a wider network of PE related BOLD activity, including the ventral striatum, globus pallidus, putamen, insula, anterior cingulate, and substantia nigra/ventral tegmental area. Haloperidol subjects did not show PE related activity in any of these regions. Conclusions Our results provide the first demonstration that the modulation of dopamine transmission affects both the physiological correlates and PE related BOLD activity during aversive learning.

Abstract

Manual drawing of regions of interest (ROIs) on brain positron emission tomography (PET) images is labour intensive and subject to intra- and inter-individual variations. To standardize analysis and improve the reproducibility of PET measures, we have developed image analysis software for automated quantification of PET data. The method is based on the individualization of a set of standard ROIs using a magnetic resonance (MR) image co-registered with the PET image. To evaluate the performance of this automated method, the software-based quantification has been compared with conventional manual quantification of PET images obtained using three different PET radiotracers: [ 11 C]-WAY 100635, [ 11 C]-raclopride and [ 11 C]-DASB. Our results show that binding potential estimates obtained using the automated method correlate highly with those obtained by trained raters using manual delineation of ROIs for frontal and temporal cortex, thalamus, and striatum (global intraclass correlation coefficient > 0.8). For the three radioligands, the software yields time–activity data that are similar (within 8%) to those obtained by manual quantification, eliminates investigator-dependent variability, considerably shortens the time required for analysis and thus provides an alternative method for accurate quantification of PET data.
