ObjectiveThe present study aims to compare the correlation dimension and second-order entropy at the minimum embedding dimension with the correlation dimension (D2) and second-order entropy (K2) based on their efficiency and accuracy in differentiating between normal and pathologic voices.MethodsThe minimum embedding dimension was estimated with the Cao method. Nonlinear dynamic parameters, such as correlation dimension and second-order entropy, were used to quantitatively analyze the normal and pathologic voice samples.ResultsThe computing time of the correlation dimension and second-order entropy at the minimum embedding dimension was reduced to approximately one third of that of traditional D2 and K2 calculations, reflecting higher efficiency. The statistical results of linear fitting suggested that the correlation dimension was highly correlated to the correlation dimension at the minimum embedding dimension, and second-order entropy calculation was highly correlated to the second-order entropy at the minimum embedding dimension. Lastly, the results of statistical comparison proved that the correlation dimension at the minimum embedding dimension and second-order entropy at the minimum embedding dimension were able to significantly differentiate between normal and disordered voices (P < 0.001).ConclusionsThe results suggest that the correlation dimension and second-order entropy at the minimum embedding dimension are valid analysis tools for the diagnosis of voice disorders. Additionally, the efficiency and accuracy of these parameters yield potential for clinical usage because of lower computation time than current methods.

What does the literature say about the needs of veterans in the areas of health?

What does the literature say about the needs of veterans in the areas of health?

Nurse Educ Today. 2016 Aug 12;

Authors: Hynes C, Thomas M

Abstract
This paper reports on a systematic review undertaken in 2013 aimed at identifying evidence and dismissing some of the myths surrounding the needs of the veteran community. Papers were retrieved from a wide range of sources to ensure that literature covered the key areas of health concerns and focused also on time spent in service. Of the twenty eight papers reviewed categories relating to mental health (including PTSD and suicide), the use of alcohol, trauma, hearing loss, cancer and obesity were identified. Outcomes from the review established that while early service leavers were the most vulnerable there were also aspects within service that had an impact on future life events such as the type of leadership experienced, the cohesion of the unit and facing combat situations. The use of alcohol as a coping mechanism is also considered prevalent with adverse effects as is the worry of family situations at home. The impact of service life on the veteran, especially if suffering trauma will have long lasting psychological and physical outcomes, although it is recognised that veterans in the main have excellent physical and psychological strength and many physical illnesses are not greatly exaggerated from that of the general public.

Psychosocial development of 5-year-old children with hearing loss: Risks and protective factors.

Psychosocial development of 5-year-old children with hearing loss: Risks and protective factors.

Int J Audiol. 2016 Aug 19;:1-12

Authors: Wong CL, Ching TY, Leigh G, Cupples L, Button L, Marnane V, Whitfield J, Gunnourie M, Martin L

Abstract
OBJECTIVE: The aims of this paper were to report on the global psychosocial functioning of 5-year-old DHH children and examine the risk and protective factors that predict outcomes.
DESIGN: A cross-sectional analysis of data collected from a prospective, population-based longitudinal study.
STUDY SAMPLE: Parents/caregivers of 356 children completed questionnaires on psychosocial development (CDI, SDQ), functional communication (PEACH) and demographic information. Children completed standardized assessments of non-verbal cognitive ability (WNV) and language (PLS-4).
RESULTS: On average, global psychosocial functioning was within the range of typically developing children; however, variability was high and 12% of children had scores that were more than 2 SDs below the norm. Non-verbal cognitive ability, presence of additional disabilities, language and functional communication significantly predicted outcomes. In contrast, type of hearing device, severity of hearing loss and age at intervention did not.
CONCLUSION: The global psychosocial functioning of this cohort of 5-year-old DHH children fell within the range of typically developing children. The findings suggest that spoken language ability and functional communication skills are vital for healthy psychosocial development.

Self-Reported Listening-Related Effort and Fatigue in Hearing-Impaired Adults.

Objective: Hearing loss may increase listening-related effort and fatigue due to the increased mental exertion required to attend to, and understand, an auditory message. Because there have been few attempts to quantify self-reported effort and fatigue in listeners with hearing loss, that was the aim of the present study. Design: Participants included three groups of hearing-impaired adults: (1) hearing aid users (HA, n = 50; 31 male, 19 female; age range = 55 to 85 years); (2) cochlear implant users (CI, n = 50; 26 male, 24 female; age range = 55 to 80 years); and (3) single sided deafness (SSD, n = 50; 30 male, 20 female; age range = 58 to 80 years). There was also a control group of adults who passed a hearing screen at 30 dB HL at the frequencies: 500, 1000, 2000, and 4000 Hz in both ears (n = 50; 22 male, 28 female; age range = 55 to 78 years). The fatigue assessment scale (FAS) was used to quantify fatigue. The FAS is a generic standardized self-report scale consisting of 10 items that are scored using a five-point Likert scale. An effort assessment scale (EAS), developed for the present study, consisted of six questions with responses provided on a visual analog scale that ranges from 0 to 10. Results: All hearing-impaired groups reported significantly increased effort and fatigue compared to the control group. The median fatigue score for the control group was 14 and around 22 for the three hearing-impaired groups. The median effort score for the control group was 20 and around 70 for the three hearing-impaired groups. There was no significant difference in mean effort or fatigue between the three groups of hearing-impaired adults. There was a weak positive correlation between fatigue and effort scores (r = 0.40, p

Psychological Therapy for People with Tinnitus: A Scoping Review of Treatment Components.

Background: Tinnitus is associated with depression and anxiety disorders, severely and adversely affecting the quality of life and functional health status for some people. With the dearth of clinical psychologists embedded in audiology services and the cessation of training for hearing therapists in the UK, it is left to audiologists to meet the psychological needs of many patients with tinnitus. However, there is no universally standardized training or manualized intervention specifically for audiologists across the whole UK public healthcare system and similar systems elsewhere across the world. Objectives: The primary aim of this scoping review was to catalog the components of psychological therapies for people with tinnitus, which have been used or tested by psychologists, so that they might inform the development of a standardized audiologist-delivered psychological intervention. Secondary aims of this article were to identify the types of psychological therapy for people with tinnitus, who were reported but not tested in any clinical trial, as well as the job roles of clinicians who delivered psychological therapy for people with tinnitus in the literature. Design: The authors searched the Cochrane Ear, Nose and Throat Disorders Group Trials Register; Cochrane Central Register of Controlled Trials; PubMed; EMBASE; CINAHL; LILACS; KoreaMed; IndMed; PakMediNet; CAB Abstracts; Web of Science; BIOSIS Previews; ISRCTN; ClinicalTrials.gov; IC-TRP; and Google Scholar. In addition, the authors searched the gray literature including conference abstracts, dissertations, and editorials. No records were excluded on the basis of controls used, outcomes reached, timing, setting, or study design (except for reviews-of the search results. Records were included in which a psychological therapy intervention was reported to address adults (
