Vitreous Fluid and/or Urine Glucose Concentrations in 1335 Civil Aviation Accident Pilot Fatalities*

Abstract: During aviation accident investigations, vitreous fluid and urine samples from pilot fatalities are analyzed for glucose and blood for hemoglobin A_1c (HbA_1c) to monitor diabetic pilots and to discover other pilots with undiagnosed/unreported diabetes. The prevalence of elevated glucose concentrations in fatally injured pilots was evaluated by searching the Civil Aerospace Medical Institute’s Toxicology Database for the period 1998–2005. Out of 1335 pilots involving 363 vitreous fluid, 365 urine, and 607 vitreous fluid and urine analyses, 43 pilots had elevated glucose in vitreous fluid (>125 mg/dL) and/or in urine (>100 mg/dL). Of the 20 pilots whose blood samples were analyzed, nine had >6% HbA_1c—four were known diabetics, and five were unknown diabetics. Urinary glucose levels were elevated in all 13 known hyperglycemic pilots. A considerable number of pilots (30 of 43) had elevated glucose and HbA_1c (5 of 20), suggesting undiagnosed/unreported diabetic conditions.     

Self-injury group psychotherapy intervention for young offenders: a pilot study

Objective: Self-injury (SI) is a significant and growing problem with the prison estate and a particularly acute issue with young offenders. Despite this, there are no evidence-based interventions for Young Offenders with SI difficulties. The Self-Injury Group Psychotherapy Intervention (SIGPI) was developed to target this.

Method: Drawing on existing evidence, the group was developed and piloted on a sample of 12 male Young Offenders (mean age 19.85 years) in custody with a history of SI. Participants were measured on observable SI behaviour, SI thoughts and urges and psychological distress. A within subject design was utilised with measures at baseline, 6 months and 1 year.

Results: At 12 months follow-up, a significant reduction in SI acts, time spent on SI monitoring, severity of urges and difficulty resisting SI. Psychological distress was also reduced.

Conclusions: SIGPI could be a potentially promising intervention and further investigation into its efficacy is warranted.
