Predictors of respiratory failure in Guillain-Barré syndrome: a 22 year cohort study from a single Italian centre.

Background And Purpose: The study aimed to identify predictors of respiratory failure leading to mechanical ventilation (MV) and tracheostomy in Guillain-Barré syndrome (GBS).

Methods: Two hundred and thirty adult cases admitted to the Neurology Unit of Modena, Italy, between January 2000 and December 2021 were studied. A cut-off of MV starting within 8 weeks from onset of weakness was used.

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.

In-hospital and out-of-hospital stroke in patients with COVID-19: two different diseases?

Background: Ischemic stroke is a known complication of COVID-19. It may have a different pathogenesis and worse outcome compared to stroke in patients without COVID-19. Furthermore, patients with COVID-19 and out-of-hospital stroke onset might have different characteristics compared to patients with COVID-19 and in-hospital stroke onset.

Defensive evaluation of antismoking messages among college-age smokers: the role of possible selves.

This study hypothesized that individuals respond to antismoking messages in a biased or defensive manner to the degree that smoking is a personally relevant activity for them. The authors operationalized the personal relevance of smoking variously as smoking behavior (smoking status, rate, duration, and recent attempts to quit), endorsement of the smoker stereotype, and importance of smoking behavior as an identity within the self-concept (current self and possible selves). In the experiment, smokers (n = 82) and nonsmokers (n = 105) privately viewed several antismoking video segments.

Flavonoids as antioxidant agents: importance of their interaction with biomembranes.

Flavonoids, a group of phenolic compounds widely occurring in the plant kingdom, have been reported to possess strong antioxidant activity. In the present study, four flavonoids (quercetin, hesperetin, naringenin, rutin), chosen according to their structural characteristics, were tested in two different in vitro experimental models: (1) Fe(2+)-induced linoleate peroxidation (Fe(2+)-ILP), by detection of conjugated dienes; and (2) autooxidation of rat cerebral membranes (ARCM), by using thiobarbituric acid for assay of free malondialdehyde production. The results obtained were also interpreted in the light of flavonoid interactions, studied by differential scanning calorimetry, with dipalmitoylphosphatidylcholine (DPPC) vesicles as a biological membrane model.
