Impaired semantic control in the logopenic variant of primary progressive aphasia.

We investigated semantic cognition in the logopenic variant of primary progressive aphasia, including (i) the status of verbal and non-verbal semantic performance; and (ii) whether the semantic deficit reflects impaired semantic control. Our hypothesis that individuals with logopenic variant of primary progressive aphasia would exhibit semantic control impairments was motivated by the anatomical overlap between the temporoparietal atrophy typically associated with logopenic variant of primary progressive aphasia and lesions associated with post-stroke semantic aphasia and Wernicke's aphasia, which cause heteromodal semantic control impairments. We addressed the presence, type (semantic representation and semantic control; verbal and non-verbal), and progression of semantic deficits in logopenic variant of primary progressive aphasia.

CFAP47 is Implicated in X-Linked Polycystic Kidney Disease.

Introduction: Autosomal dominant polycystic kidney disease (ADPKD) is a well-described condition in which approximately 80% of all cases have a genetic explanation; and among sporadic cases without a family history, the genetic bases remain unclear in approximately 30% of cases. This study aimed to identify genes associated with polycystic kidney disease (PKD) in patients with sporadic cystic kidney disease in which a clear genetic change was not identified in established genes.

Methods: A next-generation sequencing panel analyzed known genes related to kidney cysts in 118 sporadic cases, followed by whole-genome sequencing (WGS) on 47 unrelated individuals without identified candidate variants.

Prevalence of psychosocial interventions for pediatric dog bite injury: Is the bark actually worse than the bite?

Purpose: Long-term psychological effects may occur after childhood dog bite injuries. We performed a national survey to assess psychosocial interventions for children presenting with dog bite injuries to pediatric trauma centers.

Methods: A 26-question, online survey was administered to Pediatric Trauma Program Managers in the United States ( = 83).

Concurrent validity and discriminative ability of force plate measures of balance during the sub-acute stage of stroke recovery.

Background: Many objective measures of balance control, including force plate measures of standing balance, lack sufficient validation for use in the stroke population.

Research Questions: Do force plate measures of quiet standing balance during the sub-acute stage of stroke recovery have concurrent validity (i.e.

Lexical markers of disordered speech in primary progressive aphasia and 'Parkinson-plus' disorders.

Connected speech samples elicited by a picture description task are widely used in the assessment of aphasias, but it is not clear what their interpretation should focus on. Although such samples are easy to collect, analyses of them tend to be time-consuming, inconsistently conducted and impractical for non-specialist settings. Here, we analysed connected speech samples from patients with the three variants of primary progressive aphasia (semantic, svPPA = 9; logopenic, lvPPA = 9; and non-fluent, nfvPPA = 9), progressive supranuclear palsy (PSP Richardson's syndrome = 10), corticobasal syndrome (CBS = 13) and age-matched healthy controls ( = 24).
