Association between Salivary Alpha-Amylase and Executive Functioning in Healthy Children.

The main aim of this study was to confirm the relationship between executive performance and salivary alpha-amylase (SAA) activity in a sample of 64 healthy children (39 boys), and compare it to the association of SAA output and salivary flow rate (SFR). Executive functioning was assessed via fluency, trail-making, rings and inhibition tasks from the Batería de Evaluación Neuropsicológica de la Función Ejecutiva en Niños [Battery of Neuropsychological Assessment for Executive Function in Children] (ENFEN), merged into an ENFEN total score. SAA activity, output, and SFR were measured at baseline, one minute before, and one minute after the end of a neuropsychological testing session.

Association of salivary alpha-amylase and salivary flow rate with working memory functioning in healthy children.

The aim of this study was to examine the association between auditory and visual working memory (WM) performance and salivary alpha-amylase (sAA) and salivary flow rate (SFR) in a sample of 63 children (38 boys). WM was assessed by means of WISC-V subtests: four auditory subtests ( and ) and one visual subtest (). SAA activity, output, and SFR were measured at baseline (10 min prior to testing), one minute prior to testing, one minute after the end of the auditory WM subtests and one minute after the end of the visual WM subtest.

Application of κ free light chains in cerebrospinal fluid as a biomarker in multiple sclerosis diagnosis: development of a diagnosis algorithm.

Background: The determination of κ free light chains (KFLC) in cerebrospinal fluid (CSF) by nephelometry is a feasible alternative to immunoglobulin G oligoclonal bands (OCB) in the evaluation of intrathecal synthesis of immunoglobulin in multiple sclerosis (MS) and other demyelinating diseases. The aim of this study was to assess the diagnostic value of KFLC and its inclusion in a procedure algorithm along with OCB interpretation.

Methods: A cross-sectional study, which included 123 patients with a CSF OCB request, was carried out.

Mid-regional pro-adrenomedullin as prognostic biomarker in septic shock.

Background: The aim was to ascertain the prognostic value of mid-regional pro-adrenomedullin (MR-proADM), measured within 24 hours from the onset of septic shock (SS).

Methods: We performed a prospective, observational study on all patients admitted to our hospital's Intensive Care Unit with SS over a one year period from January to December 2011 to examine the outcomes in 100 consecutive SS cases. Demographic data and severity score (APACHEII and SOFA) were recorded.

Salivary alpha-amylase changes promoted by sustained exposure to affective pictures.

We studied the changes in salivary alpha-amylase (sAA) and other psychophysiological indices (heart rate, skin conductance, and corrugator supercilii activity) elicited by sustained exposure to affective pictures. Thirty-nine subjects viewed five blocks of pictures depicting mutilations, human attack, neutral scenes, sport/adventure, and erotica. Each block comprised 12 pictures of the same content.

Fear of falling among elderly patients with dizziness and syncope in a tilt setting.

The objectives of this study were to assess the prevalence of fear of falling (FOF) among patients over age 60 with dizziness, falls, or syncope; and to analyze risk factors associated with FOF, including data from the tilt table test. This study included 200 older patients referred to a geriatric outpatient clinic specializing in dizziness, falls, and syncope. The primary outcome measure was the proportion of patients who experienced FOF (yes vs.

Cognitive performance and morning levels of salivary cortisol and alpha-amylase in children reporting high vs. low daily stress perception.

The aim of the present study was to assess the effects of daily stress perception on cognitive performance and morning basal salivary cortisol and alpha-amylase levels in healthy children aged 9-12. Participants were classified by whether they had low daily perceived stress (LPS, n = 27) or a high daily perceived stress (HPS, n = 26) using the Children Daily Stress Inventory (CDSI). Salivary cortisol and alpha-amylase were measured at awakening and 30 minutes later.
