#1
Marc I Stutter, Jonathan Cains
The degradation of aquatic ecosystems by multiply-acting stressors is a key threat requiring new approaches to identify impairment processes and restoration targets. Heterotrophic respiration of C-substrates can be an integrative indicator of how aquatic ecosystems respond to pollution. We utilised sixteen C-substrates (simple metabolites to dissolved organic matter (DOM)) to characterise substrate induced respiration (SIR) for sediments from sixteen NE Scotland streams covering a range of land use-related pollution pressures...

Nichol Castro, Kristin M Pelczarski, Michael S Vitevitch
Purpose: Methods from network science have examined various aspects of language processing. Clinical populations may also benefit from these novel analyses. Phonological and lexical factors have been examined in adults who stutter (AWS) as potential contributing factors to stuttering, although differences reported are often subtle. We reexamined the performance of AWS and adults who do not stutter (AWNS) from a previously conducted lexical decision task in an attempt to determine if network science measures would provide additional insight into the phonological network of AWS beyond traditional psycholinguistic measures...

AIM: To characterize the noise and stutter distribution of 23 short tandem repeats (STRs) included in the PowerSeqTM Auto System. METHODS: Raw FASTQ files were analyzed using STRait Razor v2s to display alleles and coverage. The sequence noise was divided into several categories: noise at allele position, noise at -1 repeat position, and artifact. The average relative percentages of locus coverage for each noise, stutter, and allele were calculated from the samples used for this locus noise analysis...

PURPOSE: Neuroimaging studies in persistent developmental stuttering repeatedly report altered basal ganglia functions. Together with thalamus and cerebellum, these structures mediate sensorimotor functions and thus represent a plausible link between stuttering and neuroanatomy. However, stuttering is a complex, multifactorial disorder. Besides sensorimotor functions, emotional and social-motivational factors constitute major aspects of the disorder. Here, we investigated cortical and subcortical gray matter regions to study whether persistent developmental stuttering is also linked to alterations of limbic structures...

REVIEW
Martin Poot
Intragenic deletions of the contactin-associated protein-like 2 gene (CNTNAP2) have been found in patients with Gilles de la Tourette syndrome, intellectual disability (ID), obsessive compulsive disorder, cortical dysplasia-focal epilepsy syndrome, autism, schizophrenia, Pitt-Hopkins syndrome, stuttering, and attention deficit hyperactivity disorder. A variety of molecular mechanisms, such as loss of transcription factor binding sites and perturbation of penetrance and expressivity, have been proposed to account for the phenotypic variability resulting from CNTNAP2 mutations...

PURPOSE: Recent literature on speech production in adults who stutter (AWS) has begun to investigate the neural mechanisms characterizing speech-motor preparation prior to speech onset. Compelling evidence has suggested that stuttering is associated with atypical processing within cortical and sub-cortical motor networks, particularly in the beta frequency range, that is effective before speech production even begins. Due to low stuttering frequency in experimental settings, however, the literature has so far predominantly reported on fluent speech production in AWS...

PURPOSE: This study aims to examine the association between adults' experience of stuttering and their age, gender and marital status, as well as to evaluate the psychometric properties of the Hebrew version of the OASES-A. METHODS: The Hebrew version of the OASES-A was administered to 91 adults-who-stutter. The validity of the translated version was evaluated using a subset of 43 participants, who also completed three additional instruments: (a) a Perceived Stuttering Severity (PSS) self-rating scale, (b) the Situation Avoidance Behavior Checklist (SABC), (c) the Students Life Satisfaction scale (SLSS)...

BACKGROUND: Negative public attitudes toward stuttering have been widely reported, although differences among countries and regions exist. Clear reasons for these differences remain obscure. PURPOSE: Published research is unavailable on public attitudes toward stuttering in Portugal as well as a representative sample that explores stuttering attitudes in an entire country. This study sought to (a) determine the feasibility of a country-wide probability sampling scheme to measure public stuttering attitudes in Portugal using a standard instrument (the Public Opinion Survey of Human Attributes-Stuttering [POSHA-S]) and (b) identify demographic variables that predict Portuguese attitudes...

PURPOSE: There are theoretical and empirical reasons to consider a potential role for copper metabolism in the brain in how it could influence stuttering. However, a link between stuttering and dietary intake has never been researched in a systematic way. This pilot study therefore aimed to explore a possible association between ingested amounts of copper and thiamine (vitamin B1) with stuttering frequency using a double blind cross-over longitudinal paradigm. METHODS: 19 adults who stutter between 20 and 51 years old filled out an online survey for 9 consecutive weeks...

PURPOSE: Recent work has reported adverse effects of students' stuttering on their social and emotional functioning at school. Yet, few studies have provided an in-depth examination of classroom interaction of students who stutter (SWS). The current study uses a network perspective to compare acceptance and rejection in the classroom interaction between SWS and their peers in secondary education. METHODS: The sample comprised 22 SWS and 403 non-stuttering peers (22 classes) of secondary education in Flanders (Belgium)...

PURPOSE: Stuttering can trigger anxiety and other psychological and emotional reactions, and limit participation in society. It is possible that psychological counseling could enhance stuttering treatment outcomes; however, little is known about how clients view such counseling. The purpose of this study was to gain an understanding of clients' experiences with, and perceptions of, a psychological counseling service that was offered as an optional adjunct to speech therapy for stuttering...

A factitious disorder (FD) is a diagnostic entity in which patients intentionally act physically or mentally ill without obvious benefits and without being consciously aware of a clear underlying motive. Most pediatric FD cases have been reported as Munchausen syndrome by Proxy; however, pediatric disease symptoms can also be intentionally falsified by child and adolescent patients. To our knowledge, in the medical literature, an FD patient presenting with stuttering has not been previously reported. In this case report, we aimed to discuss the diagnosis and treatment process of FDs in children and adolescents by reporting the cases of two FD patients presenting with stuttering according to the Diagnostic and Statistical Manual of Mental Disorders-Fifth Edition...

Septic tank effluent (STE) contributes to catchment nutrient and pollutant loads. To assess the role of STE discharges in impairment of surface water, it is essential to identify the sources of pollution by tracing contaminants in watercourses. We examined tracers that were present in STE to establish their potential for identifying STE contamination in two stream systems (low and high dilution levels) against the background of upstream sources. The studied tracers were microbial, organic matter fluorescence, caffeine, artificial sweeteners and effluent chemical concentrations...

Marijuana (Cannabis sativa L.) is a plant cultivated and trafficked worldwide as a source of fiber (hemp), medicine, and intoxicant. The development of a validated method using molecular techniques such as short tandem repeats (STRs) could serve as an intelligence tool to link multiple cases by means of genetic individualization or association of cannabis samples. For this purpose, a 13 loci STR multiplex method was developed, optimized, and validated according to relevant ISFG and SWGDAM guidelines. The STR multiplex consists of 13 previously described C...

Priapism, a persistent penile erection lasting longer than 4 hours and unrelated to sexual activity, is one of the most common emergencies treated by urologists. Priapism can be categorized as ischemic, recurrent ischemic (stuttering), and non-ischemic. Advances in understanding the pathophysiology of various types of priapism have led to targeted management strategies. This review aims to provide an up-to-date picture of the pathophysiology and management of priapism. A search of Medline and PubMed for relevant publications using the term "priapism" was performed...

Purpose: Those who are socially anxious may use safety behaviors during feared social interactions to prevent negative outcomes. Safety behaviors are associated with anxiety maintenance and poorer treatment outcomes because they prevent fear extinction. Social anxiety disorder is often comorbid with stuttering. Speech pathologists reported in a recent publication (Helgadottir, Menzies, Onslow, Packman, & O'Brian, 2014a) that they often recommended procedures for clients that could be safety behaviors...

Priapism is a prolonged erection without sexual stimulation. In most cases it requires prompt management in order to avoid long-term consequences such as erectile dysfunction or penile deformity. Priapism is rare in children, but haematological diseases play an important role. The diagnosis is generally not difficult. Blood gas analysis and Doppler sonography are used to establish the form of priapism and determine its further management. The management of low-flow priapism consists of immediate blood aspiration and intracavernosal injection of sympathomimetic drugs as needed...
