DATA COLLECTION AND ANALYSIS No trials of gene therapy for haemophilia matching the inclusion criteria were identified. MAIN RESULTS No trials of gene therapy for haemophilia matching the inclusion criteria were identified. AUTHORS' CONCLUSIONS No randomised or quasi-randomised clinical trials of gene therapy for haemophilia were identified. Thus, we are unable to determine the safety and efficacy of gene therapy for haemophilia. Gene therapy for haemophilia is still in clinical investigation and there is a need for well-designed clinical trials to assess the long-term feasibility, success and risks of gene therapy for people with haemophilia.

It is unclear if certain types of anaemia particularly benefit from this treatment. We performed a post-hoc analysis of anaemic patients from a randomised trial on the 'Effect of ultra-short-term treatment of patients with iron deficiency or anaemia undergoing cardiac surgery'. We used linear regression analyses to examine the efficacy of a combination anaemia treatment compared with placebo on the following deficiencies, each representing a part of the combination treatment ferritin and transferrin saturation; endogenous erythropoietin; holotranscobalamine; and folic acid in erythrocytes. Efficacy was defined as change in reticulocyte count from baseline to the first, third and fifth postoperative days and represented erythropoietic activity in the immediate peri-operative recovery phase. In all 253 anaemic patients, iron deficiency was the most common cause of anaemia. Treatment significantly increased reticulocyte count in all regression analyses on postoperative days 1, 3 and 5 (all p less then 0.001). TAK-242 concentration Baseline ferritin and endogenous erythropoietin were negatively associated with change in reticulocyte count on postoperative day 5, with an unstandardised regression coefficient B of -0.08 (95%CI -0.14 to -0.02) and -0.14 (95%CI -0.23 to -0.06), respectively. Quadruple anaemia treatment was effective regardless of the cause of anaemia and its effect manifested early in the peri-operative recovery phase. The more pronounced a deficiency was, the stronger the subsequent boost to erythropoiesis may have been. © 2020 Association of Anaesthetists.RITP was a double-blind randomized, 78-week follow-up trial in which 109 adults with immune thrombocytopenias (ITP) who failed to achieve adequate response to steroids, were randomized to receive rituximab or placebo. Here, we provide the duration of response, splenectomy and mortality rates based on extended follow-up after completion of the RITP study. Extended follow-up data were retrospectively collected for 72 (83%) patients out of the 84 patients who were not splenectomized during the initial RITP study. For the present analysis, median [interquartile range] duration of follow-up after randomization was 72 [62-82] months. Median duration of response among patients who achieved an initial response was significantly longer in patients who received rituximab (8·2 [5·5-16·7] months) as compared to placebo (1·8 [1·3-3·6] months), P = 0·036. Overall, 35 patients underwent splenectomy (13 in the rituximab, and 22 in the placebo arm, P = 0·12). Eleven patients (10%) died during the study five in the rituximab and six in the placebo arms, including four deaths from severe bleeding. Although most rituximab-treated patients eventually relapsed, a longer duration of response and a trend towards lower splenectomy rate were observed in rituximab-treated patients. © 2020 The Authors.

METHOD Overall, 72 patients (mean [SD] age 12y 4mo [3y 1mo], range 8-18y) were randomized at a ratio of 21 to receive nabiximols (n=47; 29 males, 18 females) or placebo (n=25; 15 males, 10 females) for 12 weeks (12 sprays/day max. based on clinical response/tolerability). The primary outcome was change from baseline in level of spasticity on a 0 to 10 Numerical Rating Scale (NRS), assessed by the primary caregiver at 12 weeks. Secondary outcomes included additional measures for spasticity, sleep quality, pain, health-related quality of life, comfort, depression, and safety. RESULTS There was no significant difference in the spasticity 0 to 10 NRS between nabiximols versus placebo groups after 12 weeks. No statistically significant differences were observed for any secondary endpoint. Adverse events were predominantly mild or moderate in severity; however, three cases of hallucinations were reported. INTERPRETATION Nabiximols was generally well tolerated; however, neuropsychiatric adverse events were observed. No significant reduction in spasticity with nabiximols treatment versus placebo was observed. WHAT THIS PAPER ADDS Oromucosal nabiximols is generally well tolerated by paediatric patients. However, three cases of hallucinations were observed, one of which involved auditory hallucinations and a suicide attempt. Oromucosal nabiximols versus placebo did not reduce cerebral palsy/central nervous system injury-related spasticity. © The Authors. Developmental Medicine & Child Neurology published by John Wiley & Sons Ltd on behalf of Mac Keith Press.The study of island community assembly has been fertile ground for developing and testing theoretical ideas in ecology and evolution. The ecoevolutionary trajectory of lineages after colonization has been a particular interest, as this is a key component of understanding community assembly. In this system, existing ideas, such as the taxon cycle, posit that lineages pass through a regular sequence of ecoevolutionary changes after colonization, with lineages shifting toward reduced dispersal ability, increased ecological specialization, and declines in abundance. However, these predictions have historically been difficult to test. Here, we integrate phylogenomics, population genomics, and X-ray microtomography/3D morphometrics, to test hypotheses for whether the ecomorphological diversity of trap-jaw ants (Strumigenys) in the Fijian archipelago is assembled primarily through colonization or postcolonization radiation, and whether species show ecological shifts toward niche specialization, toward upland habitats, and decline in abundance after colonization.
