    <p><b>Objective:</b> The aim of this study was to evaluate the perinatal outcomes and postnatal follow-up of prenatally diagnosed suprarenal masses (SRMs) evaluated by magnetic resonance imaging (MRI).</p> <p><b>Methods:</b> Thirteen fetuses with SRMs detected during routine prenatal ultrasound screening were evaluated by MRI between February 2007 and May 2015. The prenatal characteristics of the masses, complications of the pregnancies, and related malformations were collected as the postnatal clinical, radiological, and pathological data.</p> <p><b>Results:</b> The median gestational age at MRI was 30 weeks (18–41), and birth weight was 3285 (1700–3750) g. The mean follow-up period was 6 years (1.3–10). We observed 69.2% of the masses, which were predominantly cystic (69.2%), located on the left side. Associated malformations were found in 23% of the fetuses, with congenital heart defects being more prevalent. During the pregnancy, 15.4% of the fetuses had involution of the SRM, and one fetus had surgical treatment and different ultrasound and MRI diagnoses. Of the 69.2% of the cases, spontaneous resolution occurred in 30.7% during the first year of life and 38.4% the masses presented without modifications or signs of regression since the neonatal period.</p> <p><b>Conclusions:</b> Prenatal SRMs were associated with congenital heart defects. Spontaneous regression and absence of modifications in the masses were commonly observed in the long-term follow-up of the SRMs.</p

    Review of studies on dynamic cerebral autoregulation in the acute phase of stroke and the relationship with clinical outcome

    Acute stroke is associated with high morbidity and mortality. In the last decades, new therapies have been investigated with the aim of improving clinical outcomes in the acute phase post stroke onset. However, despite such advances, a large number of patients do not demonstrate improvement, furthermore, some unfortunately deteriorate. Thus, there is a need for additional treatments targeted to the individual patient. A potential therapeutic target is interventions to optimize cerebral perfusion guided by cerebral hemodynamic parameters such as dynamic cerebral autoregulation (dCA). This narrative led to the development of the INFOMATAS (Identifying New targets FOr Management And Therapy in Acute Stroke) project, designed to foster interventions directed towards understanding and improving hemodynamic aspects of the cerebral circulation in acute cerebrovascular disease states. This comprehensive review aims to summarize relevant studies on assessing dCA in patients suffering acute ischemic stroke, intracerebral haemorrhage, and subarachnoid haemorrhage. The review will provide to the reader the most consistent findings, the inconsistent findings which still need to be explored further and discuss the main limitations of these studies. This will allow for the creation of a research agenda for the use of bedside dCA information for prognostication and targeted perfusion interventions

    Individual Patient Data Meta-Analysis of Dynamic Cerebral Autoregulation and Functional Outcome After Ischemic Stroke

    BACKGROUND: The relationship between dynamic cerebral autoregulation (dCA) and functional outcome after acute ischemic stroke (AIS) is unclear. Previous studies are limited by small sample sizes and heterogeneity. METHODS: We performed a 1-stage individual patient data meta-analysis to investigate associations between dCA and functional outcome after AIS. Participating centers were identified through a systematic search of the literature and direct invitation. We included centers with dCA data within 1 year of AIS in adults aged over 18 years, excluding intracerebral or subarachnoid hemorrhage. Data were obtained on phase, gain, coherence, and autoregulation index derived from transfer function analysis at low-frequency and very low-frequency bands. Cerebral blood velocity, arterial pressure, end-tidal carbon dioxide, heart rate, stroke severity and sub-type, and comorbidities were collected where available. Data were grouped into 4 time points after AIS: 3 months. The modified Rankin Scale assessed functional outcome at 3 months. Modified Rankin Scale was analyzed as both dichotomized (0 to 2 versus 3 to 6) and ordinal (modified Rankin Scale scores, 0–6) outcomes. Univariable and multivariable analyses were conducted to identify significant relationships between dCA parameters, comorbidities, and outcomes, for each time point using generalized linear (dichotomized outcome), or cumulative link (ordinal outcome) mixed models. The participating center was modeled as a random intercept to generate odds ratios with 95% CIs. RESULTS: The sample included 384 individuals (35% women) from 7 centers, aged 66.3±13.7 years, with predominantly nonlacunar stroke (n=348, 69%). In the affected hemisphere, higher phase at very low-frequency predicted better outcome (dichotomized modified Rankin Scale) at <24 (crude odds ratios, 2.17 [95% CI, 1.47–3.19]; P <0.001) hours, 24–72 (crude odds ratios, 1.95 [95% CI, 1.21–3.13]; P =0.006) hours, and phase at low-frequency predicted outcome at 3 (crude odds ratios, 3.03 [95% CI, 1.10–8.33]; P =0.032) months. These results remained after covariate adjustment. CONCLUSIONS: Greater transfer function analysis-derived phase was associated with improved functional outcome at 3 months after AIS. dCA parameters in the early phase of AIS may help to predict functional outcome
