ABSTRACT

BACKGROUND: Dementia with Lewy body (DLB) is a common neurodegenerative disease that warrants specific care, which remains largely underdiagnosed. Our objective was to assess the knowledge of DLB by health professionals in comparison with that of Alzheimer's disease (AD), to better understand the reasons of its under-diagnosis. METHODS: We conducted a descriptive and analytical study processing the results of an online questionnaire submitted to French healthcare professionals between December 1, 2020 and March 1, 2021. RESULTS: A total of 490 healthcare professionals responded to the questionnaire. We observed a poorer knowledge of DLB compared to AD both subjective as highlighted on the self-assessment questionnaires and objective since the diagnostic criteria and therapeutic specificities were less known for DLB compared to AD. CONCLUSIONS: DLB appears as a disease that is still too poorly known by health professionals. To improve training is therefore a decisive objective in order to optimize the therapeutic care and support of patients with DLB and their relatives.

ABSTRACT

After nearly three decades of observed increasing trends of Antarctic sea ice extent, in September-October-November 2016, there was a dramatic decrease. Here we document factors that contributed to that decrease. An atmosphere-only model with a specified positive convective heating anomaly in the eastern Indian/western Pacific Ocean, representing the record positive precipitation anomalies there in September-October-November 2016, produces an anomalous atmospheric Rossby wave response with mid- and high latitude surface wind anomalies that contribute to the decrease of Antarctic sea ice extent. The sustained decreases of Antarctic sea ice extent after late 2016 are associated with a warmer upper Southern Ocean. This is the culmination of a negative decadal trend of wind stress curl with positive Southern Annular Mode and negative Interdecadal Pacific Oscillation, Ekman suction that results in warmer water being moved upward in the column closer to the surface, a transition to positive Interdecadal Pacific Oscillation around 2014-2016, and negative Southern Annular Mode in late 2016.
