  • Limitations of artificial pancreas systems: cost, user training, and potential for malfunctions.
  • Future directions: development of more sophisticated control algorithms and integration with other technologies.

• B. Novel Insulin Delivery Methods (1,500 words)

  • Smart insulin: glucose-responsive insulin that adjusts its release based on blood glucose levels.
  • Oral insulin: overcoming the challenges of oral insulin delivery. Examples include insulin nanoparticles and protease inhibitors.
  • Transdermal insulin: delivering insulin through the skin using patches or microneedles.

• C. Immunotherapies for Type 1 Diabetes (1,000 words)

  • Preventing or delaying the onset of Type 1 diabetes by targeting the autoimmune process that destroys beta cells.
  • Examples of immunotherapies: anti-CD3 antibodies, teplizumab.
  • Challenges and future directions.

• D. Beta-Cell Regeneration Therapies (500 words)

  • Regenerating or replacing beta cells to restore insulin production.
  • Examples of beta-cell regeneration therapies: stem cell therapy, islet transplantation.
  • Challenges and future directions.

VI. Psychosocial Aspects of Diabetes Management (5,000 words)

• A. Diabetes Distress and Burnout (2,000 words)

  • Definition of diabetes distress: Emotional burdens, worries, and frustrations arising from living with and managing diabetes. Differentiating it from depression.
  • Factors contributing to diabetes distress: complexity of treatment, fear of complications, social stigma, financial burden.
  • Symptoms of diabetes distress: fatigue, irritability, hopelessness, difficulty concentrating, neglecting self-care.
  • Assessing diabetes distress: using validated questionnaires (e.g., Diabetes Distress Scale – DDS).
  • Strategies for managing diabetes distress:
    • Self-management education and support.
    • Problem-solving skills training.
    • Stress management techniques.
    • Cognitive behavioral therapy.
    • Support groups.
  • Preventing diabetes burnout: setting realistic goals, breaking down tasks into smaller steps, rewarding progress, seeking support from family and friends.

• B. Depression and Anxiety in Diabetes (1,500 words)

  • Increased prevalence of depression and anxiety in people with diabetes compared to the general population.
  • Bidirectional relationship between diabetes and mental health: diabetes can increase the risk of depression and anxiety, and depression and anxiety can worsen diabetes management.
  • Impact of depression and anxiety on glycemic control, adherence to treatment, and risk of complications.
  • Screening for depression and anxiety: using validated questionnaires (e.g., PHQ-9, GAD-7).
  • Treatment for depression and anxiety:
    • Psychotherapy: cognitive behavioral therapy, interpersonal therapy.
    • Pharmacotherapy: antidepressants, anti-anxiety medications.
    • Collaborative care: integrating mental health services into diabetes care.

• C. Eating Disorders in Diabetes (1,500 words)

  • Increased risk of eating disorders in people with Type 1 diabetes, particularly young women.
  • Types of eating disorders: anorexia nervosa, bulimia nervosa, binge eating disorder, diabulimia (insulin restriction).
  • Diabulimia: intentionally reducing or omitting insulin doses to lose weight. Extremely dangerous and can lead to serious complications.
  • Warning signs of eating disorders: excessive concern with weight and body shape, restrictive eating patterns, binge eating episodes, purging behaviors, insulin omission.
  • Screening for eating disorders: using validated questionnaires (e.g., SCOFF questionnaire).
  • Treatment for eating disorders:
    • Multidisciplinary approach involving medical professionals, therapists, and dietitians.
    • Nutritional rehabilitation.
    • Psychotherapy: cognitive behavioral therapy, dialectical behavior therapy.
    • Insulin management education.
