Type 2 diabetes mellitus (T2DM) increases fracture risk for a given bone mineral density (BMD), which suggests that T2DM changes bone tissue properties independently of bone mass. In this study, we assessed the effects of hyperglycemia on bone tissue compositional properties, enzymatic collagen crosslinks, and advanced glycation end-products (AGEs) in the KK-Ay murine model of T2DM using Fourier transform infrared (FTIR) imaging and high-performance liquid chromatography (HPLC). Compared to KK-aa littermate controls (n = 8), proximal femoral bone tissue of KK-Ay mice (n = 14) exhibited increased collagen maturity, increased mineral content, and less heterogeneous mineral properties.

Objectives: To contribute to the dearth of literature on the prevalence rates of psychiatric disorders in deaf adults, this study examined the diagnostic and clinical characteristics of deaf psychiatric outpatients in comparison to hearing psychiatric outpatients.

Methods: Archival clinical data for deaf adults (N=241), treated at a specialized, linguistically and culturally affirmative outpatient community mental health program from 2002 to 2010, was compared to data from a random sample of hearing adult outpatients (N=345) who were treated at the same community mental health center.

Results: In various diagnostic categories, significant differences were seen between the deaf and hearing groups: bipolar disorders (3.

Deaf youth may be more vulnerable to psychiatric disorders but very little research data is available. The current study identified prevalence rates of psychiatric disorders and examined the psychosocial needs and strengths of deaf youth aged 4-17 receiving specialized outpatient mental health services for the deaf. Compared to hearing peers, deaf youth had greater rates of attention deficit hyperactivity disorder, conduct, autism-spectrum and bipolar disorders and spent three times longer in treatment than their hearing peers.

This article reviews recent research in the area of psychotic disorders in deaf psychiatric patients. Comparisons of the rates of psychotic disorders in the deaf and hearing populations suggest that psychotic disorders occur equally as often or even somewhat less often in the deaf population as in the hearing population. Consideration is given to the limitations of this small body of research, and recommendations for future research are provided.

Archival data of seclusion and restraint events in a group of deaf adults (n = 30) was compared with a random sample of hearing adults with intellectual disabilities (ID) (n = 30) and a random sample of hearing adults without ID (n = 51) admitted to a state hospital from 1998 to 2008. Only 12% of the hearing non-ID group experienced a seclusion or restraint versus 43% of the deaf group. The ID group also showed significantly higher rates of seclusion and restraint than the hearing non-ID group (30 vs.

Objective: This study examined the diagnostic and clinical features of deaf psychiatric inpatients.

Methods: Archival clinical data for deaf and hard-of-hearing adults (N=30) were compared with data for a random sample of hearing adults (N=60) admitted to a state psychiatric hospital from 1998 to 2008.

Results: Significant differences were found between deaf and hearing inpatient groups in the frequency of impulse control disorders (23% versus 2%), pervasive developmental disorders (10% versus 0%), substance use disorders (20% versus 45%), mild mental retardation (33% versus 3%), and personality disorders (17% versus 43%).
