Natural history of apparently isolated severe fetal ventriculomegaly: perinatal survival and neurodevelopmental outcome [PDF]

Prenatal Diagnosis, 2009
AbstractObjectiveTo review the prenatal diagnosis of apparently isolated severe ventriculomegaly (SVM) in a tertiary referral fetal medicine unit and report on perinatal and neurodevelopmental outcomes.MethodsAll cases of isolated SVM referred to Fetal Medicine at the NMH between 2000 and 2008 were identified.

Adherence to Protocol Recommendations for Children With Wilms Tumour in Two Consecutive Studies in the United Kingdom and Ireland—Does Variation Matter?

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Background and Aims Wilms tumour (WT) has excellent event‐free and overall survival (OS). However, small differences exist between countries participating in the same international study. This led us to examine variation in adherence to protocol recommendations as a potential contributing factor.

Long‐term apparent survival of a cold‐stunned subpopulation of juvenile green turtles

Ecosphere, 2022
Understanding the effects of extreme weather on animal populations is fundamental to ecological and conservation sciences and species management. Climate change has resulted in both warm and cold temperature extremes, including an increased frequency of ...

Diffusion MR Characteristics Following Concurrent Radiochemotherapy Predicts Progression-Free and Overall Survival in Newly Diagnosed Glioblastoma. [PDF]

, 2015
The standard of care for newly diagnosed glioblastoma (GBM) is surgery, then radiotherapy (RT) with concurrent temozolomide (TMZ), followed by adjuvant TMZ. We hypothesized patients with low diffusivity measured using apparent diffusion coefficient (ADC)

Survival analysis for apparent diffusion coefficient measures in children with embryonal brain tumours [PDF]

Neuro-Oncology, 2012
Embryonal brain tumors constitute a large and important subgroup of pediatric brain tumors. Apparent diffusion coefficient (ADC) measures have been previously used in the analysis of these tumors. We investigated a newly described ADC-derived parameter, the apparent transient coefficient in tumor (ATCT), a measure of the gradient change of ADC from the

Sirolimus for Extracranial Arteriovenous Malformations: A Scoping Review of the Evidence in Syndromic and Non‐Syndromic Cases

Pediatric Blood &Cancer, EarlyView.
ABSTRACT Arteriovenous malformations (AVMs) are rare, high‐flow, vascular anomalies that can occur either sporadically or as part of a genetic syndrome. AVMs can progress with serious morbidity and even mortality if left unchecked. Sirolimus is an mTOR inhibitor that is effective in low‐flow vascular malformations; however, its role in AVMs is unclear.

Apparent survival and return rate in the Saffron Finch Sicalis flaveola , a species with age-related phenotypes

Journal of Field Ornithology
We studied the return rate, apparent survival, and probability of recapture of the Saffron Finch ( Sicalis flaveola pelzelni ), a thraupid with sexual dichromatism and age-related male feather phenotypes; the second-year males are dull and ...

Exceptionally high apparent adult survival in three tropical species of plovers in Madagascar

Journal of Avian Biology, 2022
Adult survival is a key component of population dynamics, and understanding variation in and the drivers of adult survival rates and longevity is critical for ecological and evolutionary studies, as well as for conservation biology and practice. Tropical

Persistence pays: how viruses promote host group survival. [PDF]

, 2009
Recently, we have realized that viruses numerically dominate all life. Although viruses are known to affect host survival in populations, this has not been previously evaluated in the context of host group selection.

Analytical results for random walks in the presence of disorder and traps

, 1999
In this paper, we study the dynamics of a random walker diffusing on a disordered one-dimensional lattice with random trappings. The distribution of escape probabilities is computed exactly for any strength of the disorder.
