TL;DR: A patient who died from the rare complication of Listeriosis in the immediate phase following alemtuzumab administration one month after discontinuing dimethyl fumarate (DMF) is reported.
Abstract: We report the case of a patient who died from the rare complication of Listeriosis in the immediate phase following alemtuzumab administration one month after discontinuing dimethyl fumarate (DMF). There is considerable overlap with typical post-infusion symptoms therefore high surveillance and low threshold for empirical or possible prophylactic antibiotic therapy is advocated.

TL;DR: The benefits of pre‐hospital emergency anaesthesia (PHEA) are controversial and patients who are hypovolaemic prior to induction of anaesthesia are at risk of severe cardiovascular instability post‐induction.
Abstract: BACKGROUND The benefits of pre-hospital emergency anaesthesia (PHEA) are controversial. Patients who are hypovolaemic prior to induction of anaesthesia are at risk of severe cardiovascular instability post-induction. This study compared mortality for hypovolaemic trauma patients (without major neurological injury) undergoing PHEA with a patient cohort with similar physiology transported to hospital without PHEA. METHODS A retrospective database review was performed to identify patients who were hypotensive on scene [systolic blood pressure (SBP) < 90 mmHg], and GCS 13-15. Patient records were reviewed independently by two pre-hospital clinicians to identify the likelihood of hypovolaemia. Primary outcome measure was mortality defined as death before hospital discharge. RESULTS Two hundred and thirty-six patients were included; 101 patients underwent PHEA. Fifteen PHEA patients died (14.9%) compared with six non-PHEA patients (4.4%), P = 0.01; unadjusted OR for death was 3.73 (1.30-12.21; P = 0.01). This association remained after adjustment for age, injury mechanism, heart rate and hypovolaemia (adjusted odds ratio 3.07 (1.03-9.14) P = 0.04). Fifty-eight PHEA patients (57.4%) were hypovolaemic prior to induction of anaesthesia, 14 died (24%). Of 43 PHEA patients (42.6%) not meeting hypovolaemia criteria, one died (2%); unadjusted OR for mortality was 13.12 (1.84-578.21). After adjustment for age, injury mechanism and initial heart rate, the odds ratio for mortality remained significant at 9.99 (1.69-58.98); P = 0.01. CONCLUSION Our results suggest an association between PHEA and in-hospital mortality in awake hypotensive trauma patients, which is strengthened when hypotension is due to hypovolaemia. If patients are hypovolaemic and awake on scene it might, where possible, be appropriate to delay induction of anaesthesia until hospital arrival.

TL;DR: Since 2000 there have been reductions in surgical and alloimmune graft failures in the UK, however, graft failure codes need to be revised if they are to remain useful and effective in epidemiological and quality improvement trials.
Abstract: Background Improvement in long-term renal allograft survival is impeded by incomplete or erroneous coding of causes of allograft loss. This study reports 13-year trends in causes of graft failure across the UK. Methods National Health Service Blood and Transplant (NHSBT) and UK Renal Registry data were linked to describe UK kidney patients transplanted in 2000-13. NHSBT graft failure categories were used, with 'other' recoded when free text was available. Adjusted analyses examined the influence of age, ethnicity and donor type on causes of graft failure. Results In 22 730 recipients, 5389 (23.7%) grafts failed within a median follow-up of 5 years. The two most frequent causes were death with a functioning graft (40.8%) and alloimmune pathology (25.0%). Graft survival was higher in recipients who were younger (mean 47.3 versus 50.7 years), received a pre-emptive transplant (20.2% versus 10.4%), spent less time on dialysis (median 1.6 versus 2.4 years) and received a living donor transplant (36.3% versus 22.2%), with no differences by sex, ethnicity or human leucocyte antigen mismatch. Allograft failure within 2 years of transplantation fell from 12.5% (2000-4) to 9.8% (2009-13). Surgical- and alloimmune-related failures decreased over time while death with a functioning graft became more common. Age, ethnicity and donor type were factors in recurrent primary disease and alloimmune pathology. Conclusions Since 2000 there have been reductions in surgical and alloimmune graft failures in the UK. However, graft failure codes need to be revised if they are to remain useful and effective in epidemiological and quality improvement trials.

TL;DR: The pharmacodynamic properties of moxifloxacin against anaerobes are different than those against aerobic species, and a >90% target achievement at MICs of <2 mg/liter is suggested.
Abstract: The antibacterial effects of moxifloxacin against Bacteroides fragilis, Clostridium perfringens, and gram-positive anaerobic cocci (GPAC) were studied in an in vitro pharmacokinetic model. Initially, a dose-ranging study with area under the concentration-time curve (AUC)/MIC ratios of 6.7 to 890 was used to investigate the effect of anaerobic conditions on the AUC/MIC antibacterial effect (ABE) relationship with Escherichia coli. The AUC/MIC ratios for 50% and 90% effects, using a log CFU drop at 24 h as the antibacterial effect measure, were 34 and 59, respectively, aerobic and 54 and 96, respectively, anaerobic. These values are not significantly different. Dose ranging at AUC/MIC ratios of 9 to 216 against the anaerobes indicated a differing AUC/MIC ABE pattern, and the AUC/MICs for 50% and 90% effects were lower: for B. fragilis, they were 10.5 and 25.7, respectively; for C. perfringens, they were 8.6 and 16.2; and for GPAC, they were 7.3 and 17.4. The maximum-effect log drops were as follows: for B. fragilis, −3.2 ± 0.2 logs; for C. perfringens, −3.7 ± 0.1 logs; and for GPAC, −2.5 ± 0.1 logs. Although the anaerobes were not eradicated, there was no emergence of resistance. Comparison of the ABE of moxifloxacin to that of ertapenem against B. fragilis indicated that moxifloxacin was superior at 24 h and 48 h. In contrast, ertapenem was superior to moxifloxacin against GPAC at 24 h and 48 h and against C. perfringens at 48 h. Both drugs performed equivalently against C. perfringens at 24 h. Monte Carlo simulations using human serum AUC data and an AUC/MIC anaerobe target of 7.5 suggests a >90% target achievement at MICs of <2 mg/liter. This divides the B. fragilis wild-type MIC distribution. The pharmacodynamic properties of moxifloxacin against anaerobes are different than those against aerobic species. The clinical implications of these differences need further exploration.

TL;DR: In this paper, the authors compared oncological outcomes of focal therapy to radical prostatectomy (RP) using prospective multicentre databases of 761 FT and 572 RP cases (November/2005-September/2018).
Abstract: Focal therapy (FT) ablates areas of prostate cancer rather than treating the whole gland. We compared oncological outcomes of FT to radical prostatectomy (RP). Using prospective multicentre databases of 761 FT and 572 RP cases (November/2005-September/2018), patients with PSA < 20 ng/ml, Gleason = 4 + 3 and stage = T2c were 1–1 propensity score-matched for treatment year, age, PSA, Gleason, T-stage, cancer core length and use of neoadjuvant hormones. FT included 1–2 sessions. Primary outcome was failure-free survival (FFS) defined by need for salvage local or systemic therapy or metastases. Differences in FFS were determined using Kaplan–Meier analysis with log-rank test. 335 radical prostatectomy and 501 focal therapy patients were eligible for matching. For focal therapy, 420 had HIFU and 81 cryotherapy. Cryotherapy was used predominantly for anterior cancer. After matching, 246 RP and 246 FT cases were identified. For radical prostatectomy, mean (SD) age was 63.4 (5.6) years, median (IQR) PSA 7.9 g/ml (6–10) and median (IQR) follow-up 64 (30–89) months. For focal therapy, these were 63.3 (6.9) years, 7.9 ng/ml (5.5–10.6) and 49 [34–67] months, respectively. At 3, 5 and 8 years, FFS (95%CI) was 86% (81–91%), 82% (77–88%) and 79% (73–86%) for radical prostatectomy compared to 91% (87–95%), 86% (81–92%) and 83% (76–90%) following focal therapy (p = 0.12). In patients with non-metastatic low- intermediate prostate cancer, oncological outcomes over 8 years were similar between focal therapy and radical prostatectomy.
