Association between cardiometabolic comorbidities and Parkinson's disease in a Mexican population.

BACKGROUND: The prevalence of Parkinson's disease (PD) increases as the population ages. Studies have shown that some cardiometabolic comorbidities could be associated with risk or protection against developing PD. A retrospective case-control study was carried out to analyze the relationship between PD and cardiometabolic comorbidities. MATERIAL AND METHODS: Subjects with PD and controls without PD were consecutively recruited. Data on type 2 diabetes mellitus, systemic arterial hypertension (SAH), dyslipidemia and body mass index were collected. Logistic regression analyses were carried out. RESULTS: A total of 781 subjects with PD (56.5% males) and 1,000 controls (44.4% males) were included. After adjusting for age and gender, SAH was found as an independent risk factor (OR: 1.32; 95% CI: 1.05-1.67; p = 0.02), and obesity as a protective factor (OR: 0.72; 95% CI: 0.56-0.93; p = 0.01). CONCLUSIONS: Subjects with SAH had a higher risk of having PD, while obese subjects had a lower risk of having PD. The relationship between cardiometabolic disease, its treatment, and PD etiopathogenesis appears to be extremely complex given the amount of contradictory data.

ANTECEDENTES: La prevalencia de la enfermedad de Parkinson (EP) aumenta a medida que la población envejece. Los estudios han demostrado que algunas comorbilidades cardiometabólicas pudieran estar asociadas con el riesgo o la protección de desarrollar la EP. Se realizó un estudio retrospectivo de casos y controles para analizar la relación entre la EP y las comorbilidades cardiometabólicas. MATERIAL Y MÉTODOS: Se reclutaron sujetos con EP y controles sin EP de forma consecutiva. Se recolectaron datos sobre diabetes mellitus tipo 2, hipertensión arterial sistémica (HTA), dislipidemia e índice de masa corporal. Se llevó a cabo análisis de regresión logística. RESULTADOS: Se incluyeron un total de 781 personas con EP (56,5% hombres) y 1,000 controles (44,4% hombres). Después de ajustar por edad y sexo, la HTA se encontró como factor de riesgo independiente (OR 1.32, IC 95% 1.05-1.67, p = 0.02) y la obesidad como factor protector (OR 0.72, IC 95% 0.56-0.93, p = 0.01). CONCLUSIONES: Los sujetos con HTA tienen un mayor riesgo de tener EP; mientras que los sujetos obesos tienen un menor riesgo de tener EP. La relación entre la enfermedad cardiometabólica, su tratamiento y etiopatogenia de la EP parece ser extremadamente compleja dada la cantidad de datos contradictorios.

Association Between Somatization and Nonmotor Symptoms Severity in People With Parkinson Disease.

OBJECTIVE: To assess the frequency of somatization and its association with motor, nonmotor symptoms, and quality of life in persons with Parkinson disease (PD). METHODS: A cross-sectional case-control study was carried out. Assessments included the List of 90 Symptoms somatic factor (SCL-90-R SOM), Movement Disorder Society Unified Parkinson's Ratings Scale (MDS-UPDRS), Non-Motor Symptom Scale (NMSS), Montreal Cognitive Assessment (MoCA), and Parkinson Questionnaire-8 (PDQ-8). RESULTS: A total 93 persons with PD and 93 controls were included. Somatization within the PD group was 2 times more frequent compared to the control group (43% vs 21.5%, P = .003). Persons with PD had higher NMSS total scores (48.6 ± 42.6 vs 28.3 ± 30.4, P = .001). Patients with PD with somatization had worst MDS-UPDRS, NMSS, MoCA, and PDQ-8 (all P < .05). CONCLUSION: Somatization is more frequent in persons with PD compared to healthy controls. Somatization in PD is associated with nonmotor symptoms and worst quality of life.

Malnutrition and Associated Motor and Non-motor Factors in People with Parkinson's Disease.

BACKGROUND: People with Parkinson's disease (PwP) are at higher risk of developing malnutrition. Several factors have been suggested to be involved including motor symptoms, non-motor symptoms, and treatment-related complications. OBJECTIVE: The objective of the study was to analyze the combined effect of motor, non-motor, and pharmacological factors in the risk of malnutrition in PwP. METHODS: Eighty-seven consecutive PwP were included in the study. Clinical data and pharmacological treatment were collected. Nutritional status was assessed using the Mini-Nutritional Assessment (MNA) questionnaire. Movement Disorder Society Unified Parkinson's Disease Rating Scale (MDS-UPDRS), Non-motor Symptoms Scale (NMSS), Hamilton Depression Rating Scale HAM-D, and Montreal Cognitive Assessment were applied. RESULTS: Thirty (34.4%) PwP were at risk of malnutrition and seven had malnutrition (8%). Abnormal nutritional status was associated with lower education, higher MDSUPDRS Parts I, II, and III and total scores, and higher scores in the NMSS domain of sleep disorders and fatigue. MDS-UPDRS motor score remained as a determinant of abnormal nutritional status, defined as MNA < 23.5, with an odds ratio 1.1 (95% confidence interval 1.01-1.10, p = 0.02). CONCLUSION: The main factor associated with nutritional status was severity of the motor symptoms as assessed by the MDS-UPDRS Part III. Non-motor symptoms and treatment-related complications were not associated with malnutrition.

Pruebas Terapéuticas Con Fines Diagnósticos En Trastornos Del Movimiento / Therapeutic Tests For The Diagnosis Of Movement Disorders

Resumen El diagnóstico en medicina tiene su piedra angular en la obtención de la historia clínica y la exploración física; sin embargo, en algunas de las patologías el uso de pruebas diagnósticas es de gran utilidad como apoyo para confirmar o descartar una enfermedad. Las pruebas diagnósticas incluyen una amplia variedad de procedimientos y dentro de estas se incluyen las pruebas terapéuticas, también llamadas desafíos o retos, en los que se administra una sustancia activa para evaluar la respuesta y apoyar la impresión diagnóstica. En el contexto de los trastornos del movimiento las pruebas terapéuticas más frecuentemente utilizadas son la de levodopa, apomorfina y etanol. En esta revisión se presenta, describe y discute el alcance y utilidad de estas.

Abstract The diagnosis in medicine has its cornerstone in obtaining the clinical history and in the physical examination. However, in some of the pathologies the use of diagnostic tests is very useful as a support to confirm or rule out a disease. Diagnostic tests include a wide variety of procedures and these include therapeutic tests, also called challenges, in which an active substance is administered to evaluate the response and support the presumptive diagnosis. In the context of movement disorders, the most frequently used therapeutic tests are those with levodopa, apomorphine and ethanol. In this review we present, describe and discuss the scope and usefulness of these challenges.
