Risperidone long-acting injectable was found to be effective in protecting from any mood/manic symptom compared to placebo , but not from depressive recurrences .
Add-on or monotherapy paliperidone palmitate in SAD patients  protected from psychotic , depressive , and manic symptoms .
In patients with BD-I with a manic episode at study enrolment , aripiprazole monohydrate significantly delayed time to recurrence of manic episodes without inducing depressive episodes .
LAIs  are effective and well-tolerated maintenance treatments for BD and SAD .
They showed better efficacy in preventing mania than depression .
LAIs may be first-line for BD-I and SAD patients with a manic predominant polarity and with non-adherence problems
Long-Acting Injectable Antipsychotics ( LAIs ) are used to overcome non-compliance in psychoses , mainly schizophrenia spectrum disorders .
We aim ed to summarize available evidence of studies comparing the efficacy of LAIs to placebo or oral medications for Bipolar Disorder ( BD ) and /or Schizoaffective Disorder ( SAD ) .
AMSTAR 2: a critical appraisal tool for systematic reviews that include randomised or non-randomised studies of healthcare interventions, or both
The number of published systematic review s of studies of healthcare interventions has increased rapidly and these are used extensively for clinical and policy decisions . Systematic review s are subject to a range of biases and increasingly include non-r and omised studies of interventions . It is important that users can distinguish high quality review s. Many instruments have been design ed to evaluate different aspects of review s , but there are few comprehensive critical appraisal instruments . AMSTAR was developed to evaluate systematic review s of r and omised trials . In this paper , we report on the updating of AMSTAR and its adaptation to enable more detailed assessment of systematic review s that include r and omised or non-r and omised studies of healthcare interventions , or both . With moves to base more decisions on real world observational evidence we believe that AMSTAR 2 will assist decision makers in the identification of high quality systematic review s , including those based on non-r and omised studies of healthcare interventions
