Rapid evaluation of stroke begins with community education to better recognise the signs and symptoms of stroke, an organised system of care by first responders and the emergency department, prompt evaluation by the stroke team, and the timely administration of reperfusion including intravenous thrombolysis and endovascular thrombectomy (EVT). In their new study [1], Novak et al. have shown that a shorter time from stroke onset to groin puncture is associated with better recanalisation. This underlines the crucial importance of time in stroke care.We report the uncommon clinical case of our patient, an 83-year-old woman with Alzheimer disease, who acquired a potentially fatal tropical infection in an open-air swimming pool in the Alps. Chromobacterium violaceum is a rare gram-negative anaerobe bacillus, generally associated with serious waterborne infections in tropical and subtropical regions. The patient presented to our emergency department with a 2-day history of fever and a small non-necrotic wound on the right leg after a minor injury 9 days before. It turned out to be the first infection in Switzerland due to C. violaceum, a deadly bacterium typical of tropical regions. C. violaceum appeared for the first time in Europe in the 2011. This is now the third documented case in less than a year and the second autochthonous infection ever in our continent. A delay in adequate treatment of this emerging pathogen may be associated with high fatality rates.BACKGROUND Improvements in detection and molecular characterization of leptomeningeal metastasis from lung cancer (LC-LM) coupled with cerebrospinal fluid (CSF)-penetrating targeted therapies have altered disease management. A barrier to formal study of these therapies in LM is quantification of disease burden. Also, outcomes of patients with targetable mutations in LC-LM are not well defined. This study employs molecular and radiographic measures of LM disease burden and correlates these with outcome. METHODS We reviewed charts of 171 patients with LC-LM treated at Memorial Sloan Kettering. A subset had MRI and CSF studies available. Radiographic involvement (n = 76) was scored by number of gadolinium-enhancing sites in 8 locations. CSF studies included cytopathology, circulating tumor cell (CTC) quantification (n = 16), and cell-free DNA (cfDNA) analysis (n = 21). Clinical outcomes were compared with Kaplan-Meier log-rank test and Cox proportional hazards methodologies. RESULTS Median overall survival was 4.2 months (95% CI 3.6-4.9); 84 patients (49%) harbored targetable mutations. Among bevacizumab-naïve patients with MRI and CSF cytology at time of LC-LM diagnosis, extent of radiographic involvement correlated with risk of death (hazard ratio [HR] 1.16; 95% CI 1.02-1.33; P = 0.03), as did CSF CTC (HR 3.39, 95% CI 1.01-11.37; P = 0.048) and CSF cfDNA concentration (HR 2.58; 95% CI 0.94-7.05; P = 0.06). Those without a targetable mutation were almost 50% more likely to die (HR 1.49; 95% CI 1.06-2.11; P = 0.02). CONCLUSIONS Extent of radiographic involvement and quantification of CSF CTC and cfDNA show promise as prognostic indicators. https://www.selleckchem.com/products/VX-770.html These findings support molecular characterization and staging for clinical management, prognostication, and clinical trial stratification of LC-LM. © The Author(s) 2019.

Deep brain stimulation of the ventral anterior limb of the internal capsule rapidly improves mood and anxiety with optimal stimulation parameters. To understand these rapid effects, we studied functional interactions within the affective amygdala circuit. We compared resting state functional MRI data during chronic stimulation versus 1 week of stimulation discontinuation in patients, and obtained two resting state scans from matched healthy volunteers to account for test-retest effects. Imaging data were analysed using functional connectivity analysis and dynamic causal modelling. Improvement in mood and anxiety following deep brain stimulation was associated with reduced amygdala-insula functional connectivity. Directional connectivity analysis revealed that deep brain stimulation increased the impact of the ventromedial prefrontal cortex on the amygdala, and decreased the impact of the amygdala on the insula. These results highlight the importance of the amygdala circuit in the pathophysiology of obsessive-compulsive disorder, and suggest a neural systems model through which negative mood and anxiety are modulated by stimulation of the ventral anterior limb of the internal capsule for obsessive-compulsive disorder and possibly other psychiatric disorders. © The Author(s) (2020).

DESIGN A cross-sectional study was conducted between April and August of 2018. SETTING AND PARTICIPANTS The study was conducted in four selected regional referral hospitals in Tanzania. All members of the quality improvement teams available during the study period were recruited. INTERVENTION Quality improvement teams and their activities. MAIN OUTCOME MEASURE The primary outcome was sustainability total scores. The secondary outcomes were process, staff and organizational sustainability scores. The sustainability of quality improvement teams was assessed by using the National Health Service Institute for Innovation and Improvement Sustainability Model self-assessment tool. RESULTS The overall mean sustainability score was 59.08 (95% CI 53.69-64.46). Tanga Regional Referral Hospital had the highest mean sustainability score of 66.
