- Objective To develop a Core Outcome Set (COS) for treatment of perinatal depression.Design Systematic overview of outcomes reported in the literature and consensus development study.SettingInternational.Population Two hundred and twenty-two participants, mainly patients, healthcare professionals and researchers, representing 13 countries.Methods A systematic overview of outcomes reported in recently published research, a two-round Delphi survey and a consensus meeting at which the final COS was decided using modified nominal group technique.Main results In the literature search, 1772 abstracts were identified and evaluated, and 165 studies were finally included in the review. In all, 106 outcomes were identified and included in the Delphi survey. In all, 222 participants registered for the first round of the Delphi survey and 151 (68%) responded. In the second round, 123 (55%) participants responded. Thirteen participants attended the consensus meeting, where the following nine outcomes were agreed upon for inclusion in the final COS: self-assessed symptoms of depression, diagnosis of depression by a clinician, parent to infant bonding, self-assessed symptoms of anxiety, quality of life, satisfaction with intervention, suicidal thoughts, attempted or committed suicide, thoughts of harming the baby, and adverse events.Conclusions The relevant stakeholders prioritised outcomes and reached consensus on a COS comprising nine outcomes. We expect that this COS will contribute to the consistency and uniformity of outcome selection and reporting in future clinical trials involving treatment of perinatal depression.

Research review (peer-reviewed)abstract
- We report on the final electroweak measurements performed with data taken at the Z resonance by the experiments operating at the electron-positron colliders SLC and LEP. The data consist of 17 million Z decays accumulated by the ALEPH, DELPHI, L3 and OPAL experiments at LEP, and 600 thousand Z decays by the SLID experiment using a polarised beam at SLC. The measurements include cross-sections, forward-backward asymmetries and polarised asymmetries. The mass and width of the Z boson, m(Z) and Gamma(Z), and its couplings to fermions, for example the p parameter and the effective electroweak mixing angle for leptons, are precisely measured: m(Z) = 91.1875 +/- 0.0021 GeV, Gamma(Z) = 2.4952 +/- 0.0023 GeV, rho(l) = 1.0050 +/- 0.0010, sin(2)theta(eff)(lept) = 0.23153 +/- 0.00016. The number of light neutrino species is determined to be 2.9840 +/- 0.0082, in agreement with the three observed generations of fundamental fermions. The results are compared to the predictions of the Standard Model (SM). At the Z-pole, electroweak radiative corrections beyond the running of the QED and QCD coupling constants are observed with a significance of five standard deviations, and in agreement with the Standard Model. Of the many Z-pole measurements, the forward-backward asymmetry in b-quark production shows the largest difference with respect to its SM expectation, at the level of 2.8 standard deviations. Through radiative corrections evaluated in the framework of the Standard Model, the Z-pole data are also used to predict the mass of the top quark, m(t) = 173(+10)(+13) GeV, and the mass of the W boson, m(W) = 80.363 +/- 0.032 GeV. These indirect constraints are compared to the direct measurements, providing a stringent test of the SM. Using in addition the direct measurements of m(t) and m(W), the mass of the as yet unobserved SM Higgs boson is predicted with a relative uncertainty of about 50% and found to be less than 285 GeV at 95% confidence level.
