Published by BMJ.A 59-year-old man, with a background of multiply relapsed myeloma, presented with a 3-week history of confusion, short-term memory impairment and behavioural changes. CT head showed bilateral white matter changes and numerous, large lytic lesions of the skull vault. MRI brain revealed multiple areas of hyperintensity on T2-weighted sequences which did not enhance (many of which showed diffusion restriction) unexpectedly bringing progressive multifocal leukoencephalopathy (PML) into the differential. Initial cerebrospinal fluid studies were largely unremarkable, aside from a mildly elevated protein; cultures were negative. PCR for the John Cunningham (JC) virus was positive. Considering the patient's medical history and rapidily progressive symptoms, a palliative approach was adopted, with the patient dying 14 days later. We present this case as an example of PML in a patient with multiple myeloma, highlighting the need to consider this diagnosis in an enlarging population of heavily treated, severely immunocompromised, patients. © BMJ Publishing Group Limited 2020.

Published by BMJ.Cases of vaping-induced lung injury have increased in the USA, resulting in a heterogeneous collection of pneumonitis patterns in persons who used electronic cigarettes. Hypersensitivity pneumonitis has been documented in several cases of first-hand electronic cigarette use; however, secondhand smoke health-related consequences have not been fully understood. We present a case of the patient who developed hypersensitivity pneumonitis secondary to exposure to secondhand smoke from electronic cigarette. We summarise the presentation and diagnostic investigation, as well as the management of this case. © BMJ Publishing Group Limited 2020. No commercial re-use. See rights and permissions. Published by BMJ.A 58-year-old woman presented to the emergency department in a district general hospital with severe abdominal pain and diarrhoea, after collapsing at home. She was admitted to the intensive care unit (ICU) in septic shock, and with acute kidney injury. An initial CT scan was suggestive of colitis. She was treated for suspected gastroenteritis and her microbiology results showed Campylobacter coli as the causative organism. She failed to respond to antibiotics, and underwent serial contrast CTs which showed no progression of colitis. Colonoscopy performed on day 10 of her admission, however, revealed fulminant colitis. After a multidisciplinary meeting among gastroenterologists, general surgeons and intensivists, the patient underwent total colectomy with ileostomy. She made a slow but steady recovery in ICU, and subsequently in the ward, and was discharged to a local community hospital for further rehabilitation. © BMJ Publishing Group Limited 2020.

Current evidence suggests that AMPARs are inserted into the postsynaptic membrane during long-term potentiation (LTP) and are removed from the membrane during long-term depression (LTD). Dephosphorylation of GluA1 at Ser845 and enhanced endocytosis are critical events in the modulation of LTD. Moreover, changes in scaffold proteins from the postsynaptic density (PSD) could be also related to AMPAR regulation in LTD. In the present study we analyzed the effect of chemical LTD (cLTD) on A-kinase anchoring protein (AKAP) 150 and AMPARs levels in mouse-cultured neurons. We show that cLTD induces AKAP150 protein degradation via proteasome, coinciding with GluA1 dephosphorylation at Ser-845 and endocytosis of GluA1-containing AMPARs. Pharmacological inhibition of proteasome activity, but not phosphatase calcineurin (CaN), reverted cLTD-induced AKAP150 protein degradation. Importantly, AKAP150 silencing ins expand our understanding of the regulatory role of AKAP150 on AMPARs dynamics at glutamatergic synapses.

DESIGN Systematic review of qualitative studies. DATA SOURCES The following databases were consulted Web of Science, MEDLINE, Scopus, CINAHL, PsycINFO and SciELO (from the beginning until 29 November 2017). The bibliographical references in the studies that were finally included in the review were also searched. STUDY SELECTION The studies had to deal with the decision-making process (already experienced by the participants) on the location of care of the elderly (adults who are 65 or older), had to use a qualitative methodology and had to be written in English or Spanish. DATA EXTRACTION AND SYNTHESIS A data extraction tool was used. Data analysis was conducted through the constant comparative method from Glaser and Strauss' grounded theory. RESULTS 46 studies were included in this review. Most of them were carried out in the USA, and in 21 of them the study population focused exclusively on the elderly. selleck chemicals This review has found that there are many participants, with different roles and degrees of involvement, who may act jointly, separately or sequentially. These participants may be the elders, family members, professionals and other relevant. CONCLUSIONS The main result of this review has been the variability found on how this decision is made, even varying the way of acting/perceiving the situation of the involved persons on certain occasions, simply due to the influence of some of the other groups of participants studied. Besides, this review has focused its results on the main participant in this process, the elders and how their family members interact with them when it comes to making this decision. This has allowed relevant results to be obtained about roles and degrees of involvement. PROSPERO REGISTRATION NUMBER CRD42018084826. © Author(s) (or their employer(s)) 2020.
