Unilateral MFB stimulation evoked strong stimulus-dependent activation of vStr tonically active neurons (TANs), presumably the cholinergic interneurons, in both hemispheres. However, the TANs' activation patterns and responsiveness depended on whether the stimulus was delivered ipsilaterally or contralaterally to the recorded neuron. These findings indicate that unilateral MFB stimulation effectively activates the vStr in both hemispheres in a stimulus-dependent manner which may serve as neuronal substrate for the formation of cue-outcome associations during reinforcement learning.<br />The purpose was to evaluate, in a consecutive series of patients with isolated acute retinal ischaemia, the proportion of patients with acute silent brain infarcts (SBIs) on diffusion-weighted imaging (DWI) and to assess risk of recurrence within 3months.<br />In all, 103 consecutive patients with isolated acute retinal ischaemia (central retinal artery occlusion, branch retinal artery occlusion or transient monocular vision loss) were included between January 2015 and December 2016. They all had cerebral magnetic resonance imaging including DWI as well as a standardized aetiological workup and 3months of follow-up. The presence of DWI-positive cerebral lesions was recorded. Main clinical and radiological characteristics between DWI-positive and DWI-negative patients were compared.<br />Of the 103 patients (including 42 transient monocular vision loss), 20 (19.5%) had SBIs on DWI, which were ipsilateral to the acute retinal ischaemia in 30% and involved different and/or multiple vascular territories in 70% of cases. Ipsilateral carotid stenosis and occlusion were respectively identified in 17 and eight patients whereas cardioaortic embolism was found in 19 patients. Overall, patients with and without acute SBIs were comparable. The topography of SBIs was related to the aetiology of the acute retinal ischaemia. At 3 months of follow-up, one patient suffered from ischaemic stroke and five had recurrent retinal ischaemia.<br />Irrespective of the baseline characteristics of the patients, SBIs are present in about 20% of patients with isolated acute retinal ischaemia and may be of interest in the aetiological workup. Overall risk of recurrence is low, favoured by rapid aetiological workup and appropriate treatment.<br />Irrespective of the baseline characteristics of the patients, SBIs are present in about 20% of patients with isolated acute retinal ischaemia and may be of interest in the aetiological workup. Overall risk of recurrence is low, favoured by rapid aetiological workup and appropriate treatment.<br />To assess very long-term outcomes of children with severe aplastic anaemia (SAA) and impact of histopathology and of different treatments over time.<br />We conducted a retrospective study of 57 consecutive patients with SAA during 1973-2019. According to period, treatment consisted of androgens, immunosuppressive treatment (IST) and haematopoietic cell transplantation (HCT) in 14, 31 and 13 patients, respectively. Histopathology immune profiles were studied on bone marrow (BM).<br />Response rate (RR) to androgens was 35%, with long-term survivorship in 4 of 5 responders. RR and 10-year overall survival (OS) after IST was 65% and 80%, respectively. RR was higher in girls (92% vs 43% in boys, P=.02). Mean baseline BM values of CD34+and of B-lymphocytes in responders vs non-responders were 1.3% vs 0 (P=.08) and 14.1% vs 9.7% (P=.07), respectively. After IST, BM cellularity gradually increased and cytotoxic T-lymphocytes decreased (time variation P=.003 and 0.07, respectively). Outcome did not differ between patients with IST or frontline HCT. Ten-year OS improved over time, increasing from 35.3% to 77.1% and 77% during 1973-1985, 1986-2003 and 2004-2019, respectively.<br />Histopathology may refine response prediction to IST.

The survival and adaptation of A. butzleri to cold temperatures remains poorly studied, although it might be of interest for food safety considerations. To address this, growth patterns of eight A. butzleri isolates were determined at 8 °C for 28 days. A. butzleri isolates showed strain-dependent behavior six isolates were unculturable after day 18, one exhibited declining but detectable cell counts until day 28 and one grew to the stationary phase level. Out of 13 A. butzleri cold shock-related genes homologous to Escherichia coli, 10 were up-regulated in response to a temperature downshift to 8 °C, as demonstrated by reverse transcription-quantitative PCR. Additionally, we compared these data with the cold-shock response in E. coli. Overall, we provide a deeper insight into the environmental adaptation capacities of A. butzleri, which we find shares similarities with the E. coli cold-shock response.<br />Older adults are often reluctant to engage in fall prevention activities.<br />To understand how older adults respond to fall prevention and identify attributes that affect their responses to fall prevention.<br />Qualitative content analysis of Fall Prevention Motivational Interviewing conversations that were conducted as an intervention for a fall prevention study in the USA. We report the methods, results and discussions using the COnsolidated criteria for REporting Qualitative research checklist.<br />Conversations from 30 participants were analysed. Participants showed various responses to fall prevention from acceptance and engagement to ambivalence to denial or giving up. Three attributes affecting how they responded to fall prevention were as follows (a) their perception of fall risks, (b) their perception about fall prevention strategies and (c) self-identity. If participants perceived that their fall risks were temporary or modifiable, they were more likely to engage in fall prevention. If participants perceived that their fall risks were permanent or unmodifiable, they seemed to have difficulty accepting fall risks or gave up engaging in fall prevention strategies.
