Healthcare workers (HCWs) not fulfilling the coronavirus disease 2019 (COVID-19) case definition underwent severe acute respiratory coronavirus virus 2 (SARS-CoV-2) screening. Risk of exposure, adherence to personal protective equipment (PPE), and symptoms were assessed. In total, 2,000 HCWs were screened: 5.5% were positive for SARS-CoV-2 by polymerase chain reaction (PCR). There were no differences in PPE use between SARS-CoV-2–positive and –negative HCWs (adherence, >90%). Nursing and kitchen staff were independently associated with positive SARS-CoV-2 results.
From his early youth Hippolyte Taine's ambition was to be a philosopher. Sainte-Beuve recognized Taine's approach as an artifice with surprising results, for what the doctoral thesis on La Fontaine actually provided was an indirect method of discussing the nature of Taine's hobby-horse: the self. Leaving aside his youthful search for the mysterious origin or hypothetical purpose of the self, Taine here claims to offer a scientific analysis of its operation through the imagination and the language of the poet. Taine's thinking was unquestionably informed by his reading of philosophy both at the Lycée Bourbon and at the Ecole Normale. Taine's idea concerned the nature of the self. His ambition was to be a philosopher but his method of inquiry was that of science and he applied it to all aspects of humanity, to literature, to art, to history and to psychology.
Local cerebral uptake of glucose labelled with fluorine-18 was measured by positron emission tomography in 13 patients with schizophrenia and 37 right-handed volunteers. Patients received no medication for a minimum of 31 days and a mean of 30 weeks. The subjects were administered the labelled deoxyglucose just after the beginning of a 32-minute sequence of blurred numbers as visual stimuli for the Continuous Performance Test. In normal controls, task performance was associated with increases in glucose metabolic rate in the right frontal and right temporoparietal regions; occipital rates were unchanged. Patients with schizophrenia showed both absolutely and relatively reduced metabolic rates in the frontal cortex and in the temporoparietal regions compared with normal controls.
