For children with sensorineural hearing loss the ability to understand wh-questions might be particularly challenging because they often have only restricted access to spoken language input during optimal periods of language acquisition. In previous research it has been suggested that this restricted input during critical stages in language acquisition might lead to syntactic deficits that persist into adolescence. In this study we want to pursue this issue by investigating the comprehension of wh-questions in German children with bilateral sensorineural hearing loss...

We consider an inhomogeneous small-world network (SWN) composed of inhibitory short-range (SR) and long-range (LR) interneurons, and investigate the effect of network architecture on emergence of synchronized brain rhythms by varying the fraction of LR interneurons plong. The betweenness centralities of the LR and SR interneurons (characterizing the potentiality in controlling communication between other interneurons) are distinctly different. Hence, in view of the betweenness, SWNs we consider are inhomogeneous, unlike the "canonical" Watts-Strogatz SWN with nearly the same betweenness centralities...

Impella (Abiomed, Danvers, MA) is an effective option for emergent treatment of critical refractory cardiogenic shock. However, in patients who have inadequate peripheral arterial access, Impella for left ventricular support sometimes requires surgical access, leading to disadvantages for emergent procedures or invasiveness for very sick patients. In addition, Impella for right ventricular support was recently reported to contribute to the management of severe biventricular dysfunction. In this report, we describe a case of refractory cardiogenic shock in a patient with inadequate vascular access who was treated with biventricular Impella via venous and caval-aortic access under conscious sedation...

Language mapping is a key goal in neurosurgical planning. fMRI mapping typically proceeds with a focus on Broca's and Wernicke's areas, although multiple other language-critical areas are now well-known. We evaluated whether clinicians could use a novel approach, including clinician-driven individualized thresholding, to reliably identify six language regions, including Broca's Area, Wernicke's Area (inferior, superior), Exner's Area, Supplementary Speech Area, Angular Gyrus, and Basal Temporal Language Area...

BACKGROUND: Falls are the leading cause of injury in stroke patients. However, the cause of a fall is complicated, and several types of risk factors are involved. Therefore, a comprehensive model to predict falls with high sensitivity and specificity is needed. METHODS: This study was a prospective study of 112 inpatients in a rehabilitation ward with follow-up interviews in patients' homes. Evaluations were performed 1 month after stroke and included the following factors: (1) status of cognition, depression, fear of fall and limb spasticity; (2) functional assessments [walking velocity and the Functional Independence Measure (FIM)]; and (3) objective, computerized gait and balance analyses...

To identify emerging interdependencies between traded stocks we investigate the behavior of the stocks of FTSE 100 companies in the period 2000-2015, by looking at daily stock values. Exploiting the power of information theoretical measures to extract direct influences between multiple time series, we compute the information flow across stock values to identify several different regimes. While small information flows is detected in most of the period, a dramatically different situation occurs in the proximity of global financial crises, where stock values exhibit strong and substantial interdependence for a prolonged period...

Psychopathology is posited to be transdiagnostically linked to chronic stress. Yet efforts to understand the specificity and directionality of these links have been sparse, and the ubiquitous comorbidity of psychopathology has made the seemingly nonspecific links between psychological disorders and chronic stress difficult to interpret. The current study used a latent dimensional bifactor model of psychopathology to account for comorbidity and a multiwave prospective design to disentangle temporal associations between psychopathology and chronic stress longitudinally during the critical adolescent period for psychopathology risk and stress reactivity...

BACKGROUND: Patients with supraventricular tachycardia (SVT) and patients with coronary artery disease (CAD) often present with similar symptoms (chest pain, shortness of breath), similar electrocardiographic changes and elevated high-sensitivity troponin (cTn). It is not clear whether troponin reflects critical CAD or is elevated due to other causes in patients presenting with SVT. The aim of this study was to assess the role of elevated troponin in patients presenting with SVT. METHODS: Patients undergoing radiofrequency ablation (RFA) for SVT and simultaneous coronary angiography at the Heart Centre Lucerne, Switzerland between January 2010 and October 2014 were included in this analysis...

The transitional period from hospital to home is critical to decreasing rates of preventable, poor post-discharge outcomes. Older adults with chronic heart failure (CHF) may be challenged to exercise during the transitional period. The purpose of the current study was to test the effects of low-intensity exercise on health-related quality of life (HRQoL), physical function, and heart function in Chinese older adults with CHF during the transitional period. The study was randomized, single-blinded, and controlled...

OBJECTIVE: Eudaemonic positive psychological health (PPH), such as purpose in life (PIL), may be maintained more than hedonic PPH, such as quality of life (QOL), for patients with amyotrophic lateral sclerosis (ALS) and their caregivers across the disease course. Furthermore, patients' and caregivers' PPH may impact one another. The present study examined (a) PIL and QOL variance structures; (b) PIL and QOL trajectories from diagnosis, approaching death, with disease severity; and (c) between-dyad and within-dyad relationships for PIL and QOL in patients with ALS and their caregivers...

Legislation and ISO 15189 international standard provide that the clinical laboratories shall organize the communication of the biological assay results, especially with the establishment of a list of critical assays, whose results shall be reported during doctor's on call period but also through restricting result transmission to biologically validated results. Actually continuous validation and immediate procession of the medical records belonging to patients in emergency situation are not always possible, because of the biologist's workload and the other activities he is responsible for...

The use of botulinum toxin A (BoNT-A) has expanded across a range of lower urinary tract conditions. This review provides an overview of the current indications for BoNT-A in the lower urinary tract and critically evaluates the published evidence within each area. The classic application of BoNT-A has been in the management of refractory neurogenic detrusor overactivity (NDO) and overactive bladder (OAB). There is a large volume of high-quality evidence, including numerous randomized placebo-controlled trials, which demonstrate the efficacy of BoNT-A over a long follow-up period...

REVIEW
Rosa C Paolicelli, Maria T Ferretti
Many diverse factors, ranging from stress to infections, can perturb brain homeostasis and alter the physiological activity of microglia, the immune cells of the central nervous system. Microglia play critical roles in the process of synaptic maturation and brain wiring during development. Any perturbation affecting microglial physiological function during critical developmental periods could result in defective maturation of synaptic circuits. In this review, we critically appraise the recent literature on the alterations of microglial activity induced by environmental and genetic factors occurring at pre- and early post-natal stages...

The infralimbic cortex (IL) mediates the extinction learning and active suppression of cocaine-seeking behavior. However, the precise temporal relationship among IL activity, lever pressing, and extinction learning is unclear. To address this issue, we employed activity-guided optogenetics in male Sprague-Dawley rats to optically silence IL pyramidal neurons for 20 s immediately following unreinforced lever presses during early extinction training after cocaine self-administration. Optical inhibition of the IL increased active lever pressing during shortened extinction sessions but did not alter the retention of the extinction learning as assessed in ensuing extinction sessions with no optical inhibition...

Sensitive periods and experience-dependent plasticity have become core issues in visual system development. Converging evidence indicates that visual experience is an indispensable factor in establishing mature visual system circuitry during sensitive periods and the visual system exhibits substantial plasticity when facing deprivation. The mechanisms that underlie the environmental regulation of visual system development and plasticity are of great interest but need further exploration. Here, we investigated a unique sample of human infants who experienced initial stage blindness (beginning at birth and lasting 2 to 8 months) before the removal of bilateral cataracts...

We conducted a critical review of the literature on recurrent use of HIV testing in men who have sex with men (MSM). We performed a narrative review of the literature in which we analyzed the various conceptions on frequent testing over time, the implications for health programs, and the main social markers that influence the incorporation of HIV testing as routine care. Although it has existed since the 1990s, recurrent testing among MSM was frequently interpreted as increased exposure to HIV due to lack of condom use, and therefore as "unnecessary" testing...
