ReviewAntifibrinolytic therapy for aneurysmal subarachnoid haemorrhage.
Rebleeding is an important cause of death and disability in people with aneurysmal subarachnoid haemorrhage. Rebleeding is probably related to the dissolution of the blood clot at the site of the aneurysm rupture by natural fibrinolytic activity. This review is an update of previously published Cochrane Reviews. ⋯ The current evidence does not support the routine use of antifibrinolytic drugs in the treatment of people with aneurysmal subarachnoid haemorrhage. More specifically, early administration with concomitant treatment strategies to prevent delayed cerebral ischaemia does not improve clinical outcome. There is sufficient evidence from multiple randomised controlled trials to incorporate this conclusion in treatment guidelines.

ReviewInterventions for the long-term prevention of hereditary angioedema attacks.
Hereditary angioedema (HAE) is a serious and potentially life-threatening condition that causes acute attacks of swelling, pain and reduced quality of life. People with Type I HAE (approximately 80% of all HAE cases) have insufficient amounts of C1 esterase inhibitor (C1-INH) protein; people with Type II HAE (approximately 20% of all cases) may have normal C1-INH concentrations, but, due to genetic mutations, these do not function properly. A few people, predominantly females, experience HAE despite having normal C1-INH levels and C1-INH function (rare Type III HAE). Several new drugs have been developed to treat acute attacks and prevent recurrence of attacks. There is currently no systematic review and meta-analysis that included all preventive medications for HAE. ⋯ The available data suggest that berotralstat, C1-INH (subcutaneous, plasma-derived, nanofiltered and recombinant), danazol and lanadelumab are effective in lowering the risk or incidence (or both) of HAE attacks. In addition, C1-INH and lanadelumab decrease the severity of breakthrough attacks (data for other drugs were not available). Avoralstat, berotralstat, C1-INH (all forms) and lanadelumab increase quality of life and do not increase the risk of adverse events, including serious adverse events. It is possible that danazol, subcutaneous C1-INH and recombinant human C1-INH are more effective than berotralstat and lanadelumab in reducing the risk of breakthrough attacks, but the small number of studies and the small size of the studies means that the certainty of the evidence is low. This and the lack of head-to-head trials prevented us from drawing firm conclusions on the relative efficacy of the drugs.

Perception is the ability to understand information from our senses. It allows us to experience and meaningfully interact with our environment. A stroke may impair perception in up to 70% of stroke survivors, leading to distress, increased dependence on others, and poorer quality of life. Interventions to address perceptual disorders may include assessment and screening, rehabilitation, non-invasive brain stimulation, pharmacological and surgical approaches. ⋯ We identified 18 eligible RCTs involving 541 participants. The trials addressed touch (three trials, 70 participants), somatosensory (seven trials, 196 participants) and visual perception disorders (seven trials, 225 participants), with one (50 participants) exploring mixed touch-somatosensory disorders. None addressed stroke-related hearing, taste, or smell perception disorders. All but one examined the effectiveness of rehabilitation interventions; the exception evaluated non-invasive brain stimulation. For our main comparison of active intervention versus no treatment or control, one trial reported our primary outcome of performance in activities of daily living (ADL): Somatosensory disorders: one trial (24 participants) compared an intervention with a control intervention and reported an ADL measure. Touch perception disorder: no trials measuring ADL compared an intervention with no treatment or with a control intervention. Visual perception disorders: no trials measuring ADL compared an intervention with no treatment or control. In addition, six trials reported ADL outcomes in a comparison of active intervention versus active intervention, relating to somatosensation (three trials), touch (one trial) and vision (two trials). AUTHORS' CONCLUSIONS: Following a detailed, systematic search, we identified limited RCT evidence of the effectiveness of interventions for perceptual disorders following stroke. There is insufficient evidence to support or refute the suggestion that perceptual interventions are effective. More high-quality trials of interventions for perceptual disorders in stroke are needed. They should recruit sufficient participant numbers, include a 'usual care' comparison, and measure longer-term functional outcomes, at time points beyond the initial intervention period. People with impaired perception following a stroke should continue to receive neurorehabilitation according to clinical guidelines.

Review Meta AnalysisNon-biologic, steroid-sparing therapies for non-infectious intermediate, posterior, and panuveitis in adults.
Non-infectious intermediate, posterior, and panuveitis (NIIPPU) represent a heterogenous collection of autoimmune and inflammatory disorders isolated to or concentrated in the posterior structures of the eye. Because NIIPPU is typically a chronic condition, people with NIIPPU frequently require treatment with steroid-sparing immunosuppressive therapy. Methotrexate, mycophenolate, cyclosporine, azathioprine, and tacrolimus are non-biologic, disease-modifying antirheumatic drugs (DMARDs) which have been used to treat people with NIIPPU. ⋯ There is a paucity of data regarding which DMARD is most effective or safe in NIIPPU. Studies in general were small, heterogenous in terms of their design and outcome measures, and often did not compare different classes of DMARD with each other. Methotrexate is probably slightly more efficacious than mycophenolate in achieving control of inflammation, including steroid-sparing control (moderate-certainty evidence), although there was insufficient evidence to prefer one medication over the other in the VKH subgroup (very low-certainty evidence). Methotrexate may result in little to no difference in safety outcomes compared to mycophenolate.

ReviewImmediate versus delayed postpartum insertion of contraceptive implant and IUD for contraception.
Long-acting reversible contraception (LARC), including intrauterine devices (IUDs) and contraceptive implants, are highly effective, reversible methods of contraception. Providing LARC methods during the postpartum period is important to support contraceptive choice, and to prevent unintended pregnancy and short interpregnancy intervals. Delaying offering contraception to postpartum people until the first comprehensive postpartum visit, traditionally at around six weeks postpartum, may put some postpartum people at risk of unintended pregnancy, either due to loss to follow-up or because of initiation of sexual intercourse prior to receiving contraception. Therefore, immediate provision of highly effective contraception, prior to discharge from hospital, has the potential to improve contraceptive use and prevent unintended pregnancies and short interpregnancy intervals. ⋯ Evidence from this updated review indicates that immediate postpartum insertion improves the initiation rate of both contraceptive implants and IUDs by the first postpartum visit compared to delayed insertion. However, it is not clear whether that there are differences in utilization rates at six and 12 months postpartum. We are uncertain whether there is any difference in the unintended pregnancy rate at 12 months. Provision of progestin-releasing implants and IUDs immediately postpartum may have little or no negative impact on breastfeeding. However, the expulsion rate of IUDs and prolonged vaginal bleeding associated with immediate implants appears to be higher.
