This study examines the relationship between the early identification of hearing loss and language outcomes for deaf/hard of hearing (D/HH) children, with bilateral or unilateral hearing loss and with or without additional disabilities. It was hypothesized that hearing loss identified by 3 months of age would be associated with better language outcomes. Using a prospective, longitudinal design, 86 families completed developmental instruments at two time points: at an average age of 14.

Congenital heart disease (CHD) is linked to an increased incidence of neurodevelopmental impairments in young patients. Given the number of published studies on this topic, a synthesis of the literature is timely and needed. We performed a systematic review and meta-analysis of the medical literature to assess the evidence linking CHD to incidence of autism spectrum disorder (ASD).

Background: A primary goal of early intervention is to assist children in achieving age-appropriate language skills. The amount of intervention a child receives is ideally based on his or her individual needs, yet it is unclear if language ability impacts amount of intervention and/or if an increased frequency of intervention sessions results in better outcomes. The purpose of this study was to determine the relationship between the frequency of early intervention sessions and vocabulary outcomes in young children with hearing loss.

Background And Methods: Despite advances in health care, the majority of children undergoing cancer treatment experience pain, particularly in the home setting. Mobile health tools provide a promising avenue to deliver pain management education and information to parents of children receiving cancer treatment. The current study describes the development and formative evaluation of a novel intervention, Cancer-Tailored Intervention for Pain and Symptoms (C-TIPS), which provides empirically-based pharmacological and non-pharmacological pain management information and coping skills training to parents of pediatric cancer patients.

Pulmonary delivery of small interfering RNA (siRNA) has huge potential for the treatment of a wide range of respiratory diseases. The ability of naked siRNA to transfect cells in the lungs without a delivery vector has prompted the investigation of whether an endogenous component is at least partially responsible for the cellular uptake of siRNA, and whether a safe and efficient delivery system could be developed from this component to further improve the transfection efficiency. Surfactant protein B (SP-B), a positively charged protein molecule found in lung surfactant, is one of the possible candidates.

Background And Objectives: To date, no studies have examined vocabulary outcomes of children meeting all 3 components of the Early Hearing Detection and Intervention (EHDI) guidelines (hearing screening by 1 month, diagnosis of hearing loss by 3 months, and intervention by 6 months of age). The primary purpose of the current study was to examine the impact of the current EHDI 1-3-6 policy on vocabulary outcomes across a wide geographic area. A secondary goal was to confirm the impact of other demographic variables previously reported to be related to language outcomes.

Objectives: All US states and territories have an Early Hearing Detection and Intervention (EHDI) program to facilitate early hearing evaluation and intervention for infants who are deaf or hard of hearing. To ensure efficient coordination of care, the state EHDI programs rely heavily on audiologists' prompt reporting of a newborn's hearing status. Several states have regulations requiring mandatory reporting of a newborn's hearing status.

Despite efforts that have been made to develop and evaluate psychosocial interventions for youth with bipolar spectrum disorders (BPSDs), there has been limited evidence regarding treatment delivery and consumer experiences in clinical settings. Two parallel web-based surveys were conducted to assess clinicians' experiences with providing psychosocial treatments to youth with BPSD, and caregivers' experiences with accessing and receiving care for their youth with BSPD. Clinicians who were members of the American Psychological Association's Division 53 listserv were invited to report on (1) their training in and knowledge of BPSD among youth; (2) types of treatments they had provided and their perceived effectiveness; (3) treatment-related challenges; and (4) further training opportunities or resources they desire.
