Dyslipidaemia is a significant risk factor for cardiovascular disease in the Mexican population. This analysis aimed to describe the baseline LDL-c levels of patients presenting to cardiovascular ...clinics and evaluate the proportion who achieved their risk-based LDL-c goals as recommended by 2021 ESC prevention guidelines.
The REMECAR registry is an observational study of patients attending a specialized cardiovascular clinic for their first visit. The cardiovascular risk was retrospectively determined using the 2021 ESC guideline stratification and the SCORE2 and SCORE-OP.
A total of 5443 patients were included in the analysis. Within this population, 55.96% presented as very high, 39.98% as high and 4.06% as moderate to low risk. 63% of the participants were not on any lipid-lowering treatment at entry, while 12.4% were receiving high-intensity statin therapy. Patients presenting with established atherosclerotic cardiovascular disease had a mean LDL-c of 90.9 ± 40.7 mg/dL. Of these, 14.1% were achieving LDL-c levels of 70–55 mg/dL and 19.3% were achieving LDL-c levels <55 mg/dL. In diabetic patients at very high risk, only 25.7% achieved their LDL-c goal. Finally, in patients without another risk factor and very high-risk evaluated by SCORE2 & SCORE-OP, only 14% of patients achieved their LDL-c goals.
An important number of patients were not receiving any lipid-lowering therapy. Furthermore, in those who were, a significant portion did not achieve LDL-c recommended thresholds. Our results underline the urgent need to improve the prescription and optimization of lipid-lowering therapy as the current management appears to be insufficient for achieving optimal recommended goals. Identifying key barriers in lipid management is fundamental to establishing better strategies and health system policies to reduce cardiovascular risk.

Blood homocysteine appears to be increased in Parkinson's disease (PD) and may play a role in the development and progression of this disorder. However, the specific contribution of abnormal ...homocysteine levels to cortical degeneration in PD remains elusive.
To characterize the cortical structural correlates of homocysteine levels in PD.
From the COPPADIS cohort, we identified a subset of PD patients and healthy controls (HC) with available homocysteine and imaging data. Surface-based vertex-wise multiple regression analyses were performed to investigate the cortical macrostructural (cortical thinning) and microstructural (increased intracortical diffusivity) correlates of homocysteine levels in this sample.
A total of 137 PD patients and 43 HC were included. Homocysteine levels were increased in the PD group (t = −2.2, p = 0.03), correlating in turn with cognitive performance (r = −0.2, p = 0.03). Homocysteine in PD was also associated with frontal cortical thinning and, in a subset of patients with available DTI data, with microstructural damage in frontal and posterior-cortical regions (p < 0.05 Monte-Carlo corrected).
Homocysteine in PD appears to be associated with cognitive performance and structural damage in the cerebral cortex. These findings not only reinforce the presence and importance of cortical degeneration in PD, but also suggest that homocysteine plays a role among the multiple pathological processes thought to be involved in its development.

We aimed to assess associations between multimodal neuroimaging measures of cholinergic basal forebrain (CBF) integrity and cognition in Parkinson's disease (PD) without dementia.
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.
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).
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.

Familial hypercholesterolemia (FH) remains underdiagnosed and undertreated.
Report the results of the first years (2017-2019) of the Mexican FH registry.
There are 60 investigators, representing 28 ...federal states, participating in the registry. The variables included are in accordance with the European Atherosclerosis Society (EAS) FH recommendations.
To date, 709 patients have been registered, only 336 patients with complete data fields are presented. The mean age is 50 (36-62) years and the average time since diagnosis is 4 (IQR: 2-16) years. Genetic testing is recorded in 26.9%. Tendon xanthomas are present in 43.2%. The prevalence of type 2 diabetes is 11.3% and that of premature CAD is 9.8%. Index cases, male gender, hypertension and smoking were associated with premature CAD. The median lipoprotein (a) level is 30.5 (IQR 10.8-80.7) mg/dl. Statins and co-administration with ezetimibe were recorded in 88.1% and 35.7% respectively. A combined treatment target (50% reduction in LDL-C and an LDL-C <100 mg/dl) was achieved by 13.7%. Associated factors were index case (OR 3.6, 95%CI 1.69-8.73, P = .002), combination therapy (OR 2.4, 95%CI 1.23-4.90, P = .011), type 2 diabetes (OR 2.8, 95%CI 1.03-7.59, P = .036) and age (OR 1.023, 95%CI 1.01-1.05, P = .033).
The results confirm late diagnosis, a lower than expected prevalence and risk of ASCVD, a higher than expected prevalence of type 2 diabetes and undertreatment, with relatively few patients reaching goals. Recommendations include, the use of combination lipid lowering therapy, control of comorbid conditions and more frequent genetic testing in the future.

Background
Detection of suicidal ideation (SI) is key for trying to prevent suicide. The aim of this study was to analyze the frequency of SI and related factors in Spanish people with Parkinson's ...Disease (PwPD) and to compare them with a control group.
Methods
PD patients and controls recruited from the Spanish cohort COPPADIS from January 2016 to November 2017 were included. Two visits were conducted: V0 (baseline); V2 (2‐year ± 1 month follow‐up). SI was defined as a score ≥1 on item nine of the Beck Depression Inventory‐II (BDI‐II). Regression analyses were conducted to identify factors related to SI.
Results
At baseline, 693 PwPD (60.2% males; 62.59 ± 8.91 years old) and 207 controls (49.8% males; 60.99 ± 8.32 years old) were included. No differences between PwPD and controls were detected in SI frequency at either V0 (5.1% 35/693 vs. 4.3% 9/207; p = 0.421) or at V2 (5.1% 26/508 vs. 4.8% 6/125; p = 0.549). Major depression (MD) and a worse quality of life were associated with SI at both visits in PwPD: V0 (MD, OR = 5.63; p = 0.003; PDQ‐39, OR = 1.06; p = 0.021); V2 (MD, OR = 4.75; p = 0.027; EUROHIS‐QOL8, OR = 0.22; p = 0.006). A greater increase in the BDI‐II total score from V0 to V2 was the only factor predicting SI at V2 (OR = 1.21; p = 0.002) along with an increase in the total number of non‐antiparkinsonian drugs (OR = 1.39; p = 0.041).
Conclusion
The frequency of SI (5%) in PwPD was similar to in controls. Depression, a worse quality of life, and a greater comorbidity were related to SI.
Key points
This study detected suicidal ideation in about 5% of people with Parkinson's disease (PwPD) and was not more frequent than in controls.
Independent factors associated with suicidal ideation were major depression, a worse quality of life, and an increase in mood impairment or comorbidity over time.
These findings suggest the importance of detecting depressive symptoms in PwPD and evaluation for suicide thoughts, especially in those PwPD with major depression.
Identifying modifiable risk factors for cognitive impairment in the early stages of Parkinson's disease (PD) and estimating their impact on cognitive status may help prevent dementia (PDD) and the ...design of cognitive trials.
Using a standard approach for the assessment of global cognition in PD and controlling for the effects of age, education and disease duration, we explored the associations between cognitive status, comorbidities, metabolic variables and lifestyle variables in 533 PD participants from the COPPADIS study.
Among the overall sample, 21% of participants were classified as PD-MCI (n = 114) and 4% as PDD (n = 26). The prevalence of hypertension, diabetes and dyslipidemia was significantly higher in cognitively impaired patients while no between-group differences were found for smoking, alcohol intake or use of supplementary vitamins. Better cognitive scores were significantly associated with regular physical exercise (p < 0.05) and cognitive stimulation (< 0.01). Cognitive performance was negatively associated with interleukin 2 (Il2) (p < 0.05), Il6 (p < 0.05), iron (p < 0.05), and homocysteine (p < 0.005) levels, and positively associated with vitamin B12 levels (p < 0.005).
We extend previous findings regarding the positive and negative influence of various comorbidities and lifestyle factors on cognitive status in early PD patients, and reinforce the need to identify and treat potentially modifiable variables with the intention of exploring the possible improvement of the global cognitive status of patients with PD.
There is a need for identifying risk factors for hospitalization in Parkinson's disease (PD) and also interventions to reduce acute hospital admission.
To analyze the frequency, causes, and ...predictors of acute hospitalization (AH) in PD patients from a Spanish cohort.
PD patients recruited from 35 centers of Spain from the COPPADIS-2015 (COhort of Patients with PArkinson's DIsease in Spain, 2015) cohort from January 2016 to November 2017, were included in the study. In order to identify predictors of AH, Kaplan-Meier estimates of factors considered as potential predictors were obtained and Cox regression performed on time to hospital encounter 1-year after the baseline visit.
Thirty-five out of 605 (5.8%) PD patients (62.5±8.9 years old; 59.8% males) presented an AH during the 1-year follow-up after the baseline visit. Traumatic falls represented the most frequent cause of admission, being 23.7% of all acute hospitalizations. To suffer from motor fluctuations (HR hazard ratio 2.461; 95% CI, 1.065-5.678; p = 0.035), a very severe non-motor symptoms burden (HR hazard ratio 2.828; 95% CI, 1.319-6.063; p = 0.008), falls (HR 3.966; 95% CI 1.757-8.470; p = 0.001), and dysphagia (HR 2.356; 95% CI 1.124-4.941; p = 0.023) was associated with AH after adjustment to age, gender, disease duration, levodopa equivalent daily dose, total number of non-antiparkinsonian drugs, and UPDRS-IIIOFF. Of the previous variables, only falls (HR 2.998; 95% CI 1.080-8.322; p = 0.035) was an independent predictor of AH.
Falls is an independent predictor of AH in PD patients.
Constipation has been linked to cognitive impairment development in Parkinson's disease (PD).
Our aim was to analyze cognitive changes observed in PD patients and controls from a Spanish cohort with ...regards to the presence or not of constipation.
PD patients and controls recruited from 35 centers of Spain from the COPPADIS cohort from January 2016 to November 2017 were followed-up during 2 years. The change in cognitive status from baseline (V0) to 2-year follow-up was assessed with the PD-CRS (Parkinson's Disease Cognitive Rating Scale). Subjects with a score ≥1 on item 21 of the NMSS (Non-Motor Symptoms Scale) at baseline (V0) were considered as "with constipation". Regression analyses were applied for determining the contribution of constipation in cognitive changes.
At V0, 39.7% (198/499) of PD patients presented constipation compared to 11.4% of controls (14/123) (p < 0.0001). No change was observed in cognitive status (PD-CRS total score) neither in controls without constipation (from 100.24±13.72 to 100.27±13.68; p = 0.971) and with constipation (from 94.71±10.96 to 93.93±13.03; p = 0.615). The PD-CRS total score decreased significantly in PD patients with constipation (from 89.14±15.36 to 85.97±18.09; p < 0.0001; Coehn's effect = -0.35) compared to patients without constipation (from 93.92±15.58 to 93.14±17.52; p = 0.250) (p = 0.018). In PD patients, to suffer from constipation at V0 was associated with a decrease in the PD-CRS total score from V0 to V2 (β= -0.1; 95% CI, -4.36 - -0.27; p = 0.026) and having cognitive impairment at V2 (OR = 1.79; 95% CI, 1.01 - 3.17; p = 0.045).
Constipation is associated with cognitive decline in PD patients but not in controls.
