OBJECTIVES: To review and update the evidence on predictors of poor outcome (death, persistent vegetative state or severe neurological disability) in adult comatose survivors of cardiac arrest, either treated or not treated with controlled temperature, to identify knowledge gaps and to suggest a reliable prognostication strategy. METHODS: GRADE-based systematic review followed by expert consensus achieved using Web-based Delphi methodology, conference calls and face-to-face meetings. Predictors based on clinical examination, electrophysiology, biomarkers and imaging were included. RESULTS AND CONCLUSIONS: Evidence from a total of 73 studies was reviewed. The quality of evidence was low or very low for almost all studies. In patients who are comatose with absent or extensor motor response at ?72h from arrest, either treated or not treated with controlled temperature, bilateral absence of either pupillary and corneal reflexes or N20 wave of short-latency somatosensory evoked potentials were identified as the most robust predictors. Early status myoclonus, elevated values of neuron specific enolase at 48-72h from arrest, unreactive malignant EEG patterns after rewarming, and presence of diffuse signs of postanoxic injury on either computed tomography or magnetic resonance imaging were identified as useful but less robust predictors. Prolonged observation and repeated assessments should be considered when results of initial assessment are inconclusive. Although no specific combination of predictors is sufficiently supported by available evidence, a multimodal prognostication approach is recommended in all patients.

BACKGROUND:: Although the surgical treatment of full-thickness macular hole is well established, the utility of pars plana vitrectomy in the treatment of lamellar macular hole (LMH) remains less clear. The purpose of the study is to report functional results of surgical treatment of LMH associated with epiretinal membrane. METHODS:: Retrospective chart review of patients undergoing pars plana vitrectomy and peeling of epiretinal membrane and internal limiting membrane, with or without air or gas tamponade, for symptomatic LMH associated with epimacular membrane. RESULTS:: Forty-five eyes of 44 patients were operated for LMH associated with epimacular membrane between May 2000 and July 2009. Pars plana vitrectomy and membrane peeling were combined with air or gas tamponade in 43 of 45 cases. Mean logarithm of the minimum angle of resolution best-corrected visual acuity improved from 0.4 preoperatively to 0.13 postoperatively (P < 0.0001). Improvement in visual acuity ranged from 0 Early Treatment Diabetic Retinopathy Study (ETDRS) lines to 8.9 ETDRS lines (mean, 2.65 ETDRS lines). Visual acuity improved by ≥1 ETDRS line(s) in 40 of 45 eyes (89%) and by ≥2 ETDRS lines in 26 of 45 eyes (58%) after the surgical procedure. No patient lost vision. CONCLUSION:: This small retrospective study suggests that surgical treatment of LMH associated with epimacular membrane may improve visual acuity in symptomatic patients.
