Gender may be related to the side of the motor syndrome and cognition in idiopathic Parkinson's disease.

BACKGROUND: and Sex and cognitive profile may be related to the laterality of motor symptoms in idiopathic Parkinson's disease. INTRODUCTION: Parkinson's disease (PD) is well recognised as an inherently asymmetric disease with unilateral onset of motor symptoms. The laterality of motor symptoms may be linked to sex, clinical and demographic variables, and neuropsychological disorders. However, the available data are inconsistent. This study aimed to explore the potential association between the laterality of motor symptoms and clinical and demographic variables and deficits in specific cognitive domains. MATERIAL AND METHODS: We retrospectively recruited 97 participants with idiopathic PD without dementia; 60 presented motor symptoms on the left side and 37 on the right side. Both groups were comparable in terms of age, age at disease onset, disease duration, and severity of the neurological deficits according to the Unified Parkinson's Disease Rating Scale and the Hoehn and Yahr scale. RESULTS: Participants with left-side motor symptoms scored lower on the Schwab and England Activities of Daily Living scale. Our sample included more men than women (67% vs. 33%). Both sexes were not equally represented in the 2 groups: there were significantly more men than women in the group of patients with left-side motor symptoms (77% vs. 23%), whereas the percentages of men and women in the group of patients with right-side motor symptoms were similar (51% vs. 49%). Both groups performed similarly in all neuropsychological tasks, but women, independently of laterality, performed better than men in the naming task. CONCLUSION: We found a clear prevalence of men in the group of patients with left-side motor symptoms; this group also scored lower on the Schwab and England Scale. Female sex was predictive of better performance in the naming task. Sex should always be considered in disorders that cause asymmetric involvement of the brain, such as PD.

Introducción: La enfermedad de Parkinson (EP) es una enfermedad asimétrica en la que los primeros síntomas se presentan solo en un lado del cuerpo. El lado de inicio de la sintomatología puede depender del sexo, de variables clínicas y demográficas y de la presencia de trastornos neuropsicológicos. Sin embargo, la evidencia disponible no es consistente. Nuestro estudio pretende determinar si el lado que presenta síntomas motores tiene alguna relación con variables clínicas y demográficas y con déficits en determinados dominios cognitivos. Materiales y métodos: Incluimos 97 individuos con EP y sin demencia; 60 de ellos tenían síntomas motores en el lado izquierdo y 37 en el lado derecho. Ambos grupos presentaban similitudes en cuanto a edad, edad de inicio de la enfermedad, duración de la enfermedad, y gravedad de los síntomas neurológicos, según la Unified Parkinson's Disease Rating Scale y la Hoehn and Yahr Scale. Resultados: Los participantes con síntomas en el lado izquierdo obtuvieron puntuaciones más bajas en la Escala de Actividades de la Vida Diaria de Schwab y England. Nuestra muestra incluía más hombres que mujeres (67 vs. 33%). Además, la distribución de hombres y mujeres no era equitativa entre los dos grupos; había un número significativamente mayor de hombres en el grupo de pacientes con síntomas en el lado izquierdo (77 vs. 23%), mientras que la distribución por sexo era similar en el grupo de pacientes con síntomas en el lado derecho (51 vs. 49%). No encontramos diferencias en las puntuaciones de ninguna de las pruebas neuropsicológicas entre los grupos. Sin embargo, las mujeres, independientemente del lado afecto, obtuvieron mejores resultados que los hombres en la prueba de denominación. Conclusiones: Los hombres eran mucho más numerosos en el grupo de pacientes con afectación del lado izquierdo; este grupo mostró peores puntuaciones en la escala de Schwab y England...(AU)

Polypharmacy is a determinant of hospitalization in Parkinson's disease.

OBJECTIVE: Patients with Parkinson's disease (PD) are at a higher risk of hospitalization and recurrent hospitalizations, with consequent complications. Polypharmacy is associated with several adverse outcomes, including hospitalization, increased length of hospital stay, and mortality. The aim of this study was to evaluate among patients with PD the association between the number of medications and incident hospitalizations. PATIENTS AND METHODS: We analysed the data of 165 patients with Parkinson's disease attending a geriatric Day Hospital who were enrolled in a cohort study and followed for a median of two years. RESULTS: Over the follow-up, 46 participants (46%) were hospitalized at least one time; multiple admissions were observed in 12 subjects (7%). The median number of agents was 5 (4-7). In Cox regression, the number of drugs was associated with increased hospitalization rates (HR=1.23; 95% CI=1.06-1.43), also after excluding non-neurological medications (HR=1.18; 95% CI=1.01-1.38). Using Poisson regression, polypharmacy (i.e., use of >5 drugs) predicted the number of repeated hospitalizations (IRR=2.62; 95% CI=1.28-5.36; p=.008). CONCLUSIONS: Among patients with PD, the number of daily medications is associated with increased risk of hospitalization; an increasing number of drugs is associated with increasing number of hospitalizations.

Assessment of neurological manifestations in hospitalized patients with COVID-19.

BACKGROUND AND PURPOSE: The objective of this study was to assess the neurological manifestations in a series of consecutive severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2)-positive patients, comparing their frequency with a population hospitalized in the same period for flu/respiratory symptoms, finally not related to SARS-CoV-2. METHODS: Patients with flu/respiratory symptoms admitted to Fondazione Policlinico Gemelli hospital from 14 March 2020 to 20 April 2020 were retrospectively enrolled. The frequency of neurological manifestations of patients with SARS-CoV-2 infection was compared with a control group. RESULTS: In all, 213 patients were found to be positive for SARS-CoV-2, after reverse transcriptase polymerase chain reaction on nasal or throat swabs, whilst 218 patients were found to be negative and were used as a control group. Regarding central nervous system manifestations, in SARS-CoV-2-positive patients a higher frequency of headache, hyposmia and encephalopathy always related to systemic conditions (fever or hypoxia) was observed. Furthermore, muscular involvement was more frequent in SARS-CoV-2 infection. CONCLUSIONS: Patients with COVID-19 commonly have neurological manifestations but only hyposmia and muscle involvement seem more frequent compared with other flu diseases.

Laterality in Parkinson's disease may predict motor and visual imagery abilities.

Experimental evidence suggests that motor imagery (MI) engages the same neural substrates supporting actual motor activities and is likely impaired when such substrates are damaged, as in Parkinson's disease (PD). MI intuitively relies on visual imagery (VI), because mental simulations of physical movements depend on the visual retrieval of these movements. Although VI is generally considered a right hemispheric function, the hemispheric dominance of MI is still in dispute. Disparities in sidedness of motor disturbances are a distinctive feature of PD, and recent findings indicate that such disparities may similarly characterize cognition. Specifically, the deficits observed may depend upon which hemisphere is principally involved. Essentially, MI and VI are cognitive tasks subject to differential impairment and reflecting the prevalence of hemispheric impairment in PD. Motor imagery (assessed by the Vividness of Motor Imagery Questionnaire [VMIQ]) and VI (assessed by the Vividness of Visual Imagery Questionnaire [VVIQ] and Test of Visual Imagery Control [TVIC]) were examined in patients with asymmetric PD and in healthy elderly control subjects (HC group). VMIQ scores were similar in PD laterality subsets and the HC group, but VVIQ scores were significantly lower in both PD groups compared with the HC group. TVIC scores were significantly lower in the presence of left motor (right hemispheric) impairment and were predictive of left motor (right hemispheric) impairment. We suspect that MI is strongly reliant on VI and that language may mediate these two functions, to the extent that both are evoked through verbal stimuli. Working memory, both visual and verbal, is also involved in MI and VI tasks. Without due attention to laterality of symptoms, any training incorporating MI and VI may not deliver expected outcomes in the setting of asymmetric PD symptomatology.

[Proposal for an evaluation method of the psyco-social risks (stress) and for the orientation of the sanitary surveillance]. / Proposta di un metodo per la valutazione dei rischi psicosociali (stress) e di orientamento per la sorveglianza sanitaria.

The interest for the problematics linked to the stress in work environments has been till now limited to the consideration of its effects on health, even if the D.Lgs 626/94 obliges the employer to evaluate also the psyco-social risk, as has confirmed a sentence of the European Court of Justice. The present survey, lacking valid instruments to be found in literature, aims to experiment and evaluate a principle for the identification of causes, thus creating a model for the evaluation of risk also according to the indications published in the Document for the Consent of SIMLII in 2005, which can be used by Prevention and Protection Services and by Competent Medical Doctors. In the area of risks evaluation and of the attainment deriving from them. The model of evaluation of the risk deriving from work organization (stress), object of the present survey, has been sperimented in a sample composed of 268 employees in 13 municipal administration belonging to biographically known categories for stress risk afferent to 23 homogenuous organizational structures (traffic officers and nursery school teachers). The valued risk has been introduced in the VDR document and the indications for the sanitary surveillance have been formulated.
