In vivo cholinergic basal forebrain degeneration and cognition in Parkinson's disease: Imaging results from the COPPADIS study

COPPADIS Study Group.[Introduction] We aimed to assess associations between multimodal neuroimaging measures of cholinergic basal forebrain (CBF) integrity and cognition in Parkinson's disease (PD) without dementia.[Methods] The study included a total of 180 non-demented PD patients and 45 healthy controls, who underwent structural MRI acquisitions and standardized neurocognitive assessment through the PD-Cognitive Rating Scale (PD-CRS) within the multicentric COPPADIS-2015 study. A subset of 73 patients also had Diffusion Tensor Imaging (DTI) acquisitions. Volumetric and microstructural (mean diffusivity, MD) indices of CBF degeneration were automatically extracted using a stereotactic CBF atlas. For comparison, we also assessed multimodal indices of hippocampal degeneration. Associations between imaging measures and cognitive performance were assessed using linear models.[Results] Compared to controls, CBF volume was not significantly reduced in PD patients as a group. However, across PD patients lower CBF volume was significantly associated with lower global cognition (PD-CRStotal: r = 0.37, p < 0.001), and this association remained significant after controlling for several potential confounding variables (p = 0.004). Analysis of individual item scores showed that this association spanned executive and memory domains. No analogue cognition associations were observed for CBF MD. In covariate-controlled models, hippocampal volume was not associated with cognition in PD, but there was a significant association for hippocampal MD (p = 0.02).[Conclusions] Early cognitive deficits in PD without dementia are more closely related to structural MRI measures of CBF degeneration than hippocampal degeneration. In our multicentric imaging acquisitions, DTI-based diffusion measures in the CBF were inferior to standard volumetric assessments for capturing cognition-relevant changes in non-demented PD.This work was supported by the Alzheimer Forschung Initiative e.V.

Introduction: We aimed to assess associations between multimodal neuroimaging measures of cholinergic basal forebrain (CBF) integrity and cognition in Parkinson’s disease (PD) without dementia. Methods: The study included a total of 180 non-demented PD patients and 45 healthy controls, who underwent structural MRI acquisitions and standardized neurocognitive assessment through the PD-Cognitive Rating Scale (PD-CRS) within the multicentric COPPADIS-2015 study. A subset of 73 patients also had Diffusion Tensor Imaging (DTI) acquisitions. Volumetric and microstructural (mean diffusivity, MD) indices of CBF degeneration were automatically extracted using a stereotactic CBF atlas.

Clinical and structural brain correlates of hypomimia in early-stage Parkinson's disease

Altres ajuts: acord transformatiu CRUE-CSICBackground and purpose: Reduced facial expression of emotions is a very frequent symptom of Parkinson's disease (PD) and has been considered part of the motor features of the disease. However, the neural correlates of hypomimia and the relationship between hypomimia and other non-motor symptoms of PD are poorly understood. Methods: The clinical and structural brain correlates of hypomimia were studied. For this purpose, cross-sectional data from the COPPADIS study database were used. Age, disease duration, levodopa equivalent daily dose, Unified Parkinson's Disease Rating Scale part III (UPDRS-III), severity of apathy and depression and global cognitive status were collected. At the imaging level, analyses based on gray matter volume and cortical thickness were used. Results: After controlling for multiple confounding variables such as age or disease duration, the severity of hypomimia was shown to be indissociable from the UPDRS-III speech and bradykinesia items and was significantly related to the severity of apathy (β = 0.595; p < 0.0001). At the level of neural correlates, hypomimia was related to motor regions brodmann area 8 (BA 8) and to multiple fronto-temporo-parietal regions involved in the decoding, recognition and production of facial expression of emotions. Conclusion: Reduced facial expressivity in PD is related to the severity of symptoms of apathy and is mediated by the dysfunction of brain systems involved in motor control and in the recognition, integration and expression of emotions. Therefore, hypomimia in PD may be conceptualized not exclusively as a motor symptom but as a consequence of a multidimensional deficit leading to a symptom where motor and non-motor aspects converge

[Myocarditis related SARS-CoV-2 infection or vaccination: an expert consensus statement on its diagnosis and management].

The severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) pandemic has revealed several cardiovascular complications, including myocarditis caused by SARS-CoV-2 infection (COVID-19) or after messenger RNA vaccine administration. Because of the high prevalence of COVID-19, the expansion of vaccination programs, and the appearance of new information on myocarditis in these contexts, there is a need to condense the knowledge acquired since the start of the pandemic. To meet this need, this document was drafted by the Myocarditis Working Group of the Heart Failure Association of the Spanish Society of Cardiology, with the collaboration of the Spanish Agency for Medicines and Health Products (AEMPS). The document aims to address the diagnosis and treatment of cases of myocarditis associated with SARS-CoV-2 infection or messenger RNA vaccine administration.S

Frailty is an independent prognostic marker in elderly patients with myocardial infarction.

Acute coronary syndrome (ACS) patients are increasingly older. Conventional prognostic scales include chronological age but do not consider vulnerability. In elderly patients, a frail phenotype represents a better reflection of biological age. This study aims to determine the prevalence of frailty and its influence on patients age ≥75 years with ACS. Patients age ≥75 years admitted due to type 1 myocardial infarction were included in 2 tertiary hospitals, and clinical data were collected prospectively. Frailty was defined at admission using the previously validated Survey of Health Ageing and Retirement in Europe Frailty Index (SHARE-FI) tool. The primary endpoint was the combination of death or nonfatal myocardial reinfarction during a follow-up of 6 months. Major bleeding (hemoglobin decrease ≥3 g/dL or transfusion needed) and readmission rates were also explored. A total of 234 consecutive patients were included. Frail patients (40.2%) had a higher-risk profile, based on higher age and comorbidities. On multivariate analysis, frailty was an independent predictor of the combination of death or nonfatal myocardial reinfarction (adjusted hazard ratio [aHR]: 2.54, 95% confidence interval [CI]: 1.12-5.79), an independent predictor of the combination of death, nonfatal myocardial reinfarction, or major bleeding (aHR: 2.14, 95% CI: 1.13-4.04), and an independent predictor of readmission (aHR: 1.80, 95% CI: 1.00-3.22). Frailty phenotype at admission is common among elderly patients with ACS and is an independent predictor for severe adverse events. It should be considered in future risk-stratification models

Recomanacions per a l’organització del tractament del xoc cardiogènic a Catalunya: via xoc

Xoc cardiogènic; Tractament; Via xocCardiogenic shock; Treatment; Via xoc;Choque cardiogénico; Tratamiento; Via xocEl xoc cardiogènic (XC) és una situació de baix cabal cardíac que s’associa a hipoperfusió i fallida orgànica multisistèmica. La causa més freqüent és l’infart agut de miocardi amb disfunció greu del ventricle esquerre. Els avenços en la teràpia de reperfusió han millorat la supervivència del XC, però la mortalitat intrahospitalària continua sent elevada (al voltant del 50%). Els sistemes coordinats regionals d’atenció mèdica, associats a algorismes de tractament comuns, han millorat la supervivència en patologies agudes greus en què el pronòstic és dependent del temps (infart agut de miocardi [IAM], accident vascular cerebral, aturada cardíaca extrahospitalària, politraumatisme). Aplicar una estratègia similar adaptada al XC podria tenir un efecte similar en la seva supervivència.Cardiogenic shock (CS) is a situation of low cardiac output that is associated with hypoperfusion and multisystemic organ failure. The most common cause is acute myocardial infarction with severe left ventricular dysfunction. Advances in reperfusion therapy have improved CS survival, but in-hospital mortality remains high (around 50%). Coordinated regional health care systems, associated with common treatment algorithms, have improved survival in severe acute conditions in which the prognosis is time-dependent (acute myocardial infarction [AMI], stroke, outpatient cardiac arrest, polytrauma). Applying a similar strategy adapted to the CS could have a similar effect on its survival.El shock cardiogénico (SC) es una situación de bajo gasto cardíaco que se asocia a hipoperfusión y quiebra orgánica multisistémica. La causa más frecuente es el infarto agudo de miocardio con disfunción grave del ventrículo izquierdo. Los avances en la terapia de reperfusión han mejorado la supervivencia del SC, pero la mortalidad intrahospitalaria sigue siendo elevada (alrededor del 50%). Los sistemas coordinados regionales de atención médica, asociados a algoritmos de tratamiento comunes, han mejorado la supervivencia en patologías agudas graves en que el pronóstico es dependiente del tiempo (infarto agudo de miocardio [IAM], accidente vascular cerebral, paro cardíaco extrahospitalaria, politraumatismo). Aplicar una estrategia similar adaptada al SC podría tener un efecto similar en su supervivencia

High ultrasensitive serum C-reactive protein may be related to freezing of gait in Parkinson’s disease patients

COPPADIS Study Group.C-reactive protein (CRP) is a biomarker of systemic inflammation that has been linked to accelerated decline in walking speed in older adults. The aim of the present study was to compare the CRP levels of PD patients with vs patients without freezing of gait (FOG). Patients and controls participating in the COPPADIS-2015 study that performed blood extraction for determining molecular serum biomarkers were included. Patients with FOG were identified as those with a score of 1 or greater on item-3 of the Freezing of Gait Questionnaire (FOG-Q). Immunoassay was used for determining ultrasensitive CRP (US-CRP) level (mg/dL). In the PD group (n = 225; 61.8 ± 9.5 years old, 61.8% males), 32% of the patients presented FOG but none in the control group (n = 65; 60.3 ± 6.1 years old, 56.9% males) (p < 0.0001). Differences in US-CRP level were significant in patients with FOG vs patients without FOG and vs controls (0.31 ± 0.52 vs 0.16 ± 0.21 vs 0.21 ± 0.22; p = 0.04). Significant differences were also observed between patients with vs without FOG (p = 0.001) but not between patients and controls (p = 0.163). US-CRP level was related to FOG (OR = 4.369; 95% CI 1.105–17.275; p = 0.036) along with H&Y (OR = 2.974; 95% CI 1.113–7.943; p = 0.030) and non-motor symptoms burden (NMSS total score; OR = 1.017; 95% CI 1.005–1.029; p = 0.006) after adjusting for age, gender, disease duration, equivalent daily levodopa dose, number of non-antiparkinsonian drugs per day, motor fluctuations, cognition, motor phenotype, and chronic use of anti-inflammatory drugs. The present study suggests that serum US-CRP level is related to FOG in PD patients. Inflammation could be linked to FOG development.Santos-García D. has received honoraria for educational presentations and/or advice service by Abbvie, UCB Pharma, Lundbeck, KRKA, Zambon, Bial, and Teva. de Deus Fonticoba T. has received honoraria for educational presentations and advice service by Abbvie.
