Abstract:
Eating disorders (EDs) and post-traumatic stress disorder (PTSD) are highly comorbid. However, specific mechanisms by which PTSD-ED comorbidity is maintained are unknown. The current study constructed two PTSD-ED comorbidity networks (25 EDs and 17 PTSD symptoms) in two samples: a clinical (N = 158 individuals with an ED diagnosis) and a nonclinical sample (N = 300 college students). Glasso networks were constructed to identify (1) pathways between disorders (bridge symptoms) and (2) core symptoms. Three illness pathways emerged: between binge eating and irritability, between desire for a flat stomach and disturbing dreams, and between concentration problems and weight and shape-related concentration problems. Our findings suggest that pathways between binge eating and irritability, body dissatisfaction and trauma reminders, and concentration difficulties may be the mechanisms by which comorbidity is maintained. Interventions disrupting these pathways and targeting core and bridge symptoms may be more efficient than traditional treatment approaches.

Bone deposition is also affected by the levels of sex hormones like estrogen and testosterone that promote osteoblast activity and bone matrix synthesis. When the level of these hormones decreases due to aging, it causes a reduction in bone deposition. As a result, bone resorption by osteoclasts...
01:27Disorders of Erythrocytes
Erythrocyte disorders can be broadly categorized into two main types: anemic and polycythemic conditions.
A low oxygen-carrying capacity of the blood due to the loss, lower production, or destruction of erythrocytes is termed anemia. Hemorrhagic anemia, for example, occurs when bleeding from an external wound or internal ulcer reduces erythrocyte counts.

Leukopenia may result from bone marrow disorders, autoimmune diseases, and infectious diseases. For example, conditions such as multiple myeloma and aplastic anemia can impair the bone marrow's ability to produce adequate leukocytes. Similarly, autoimmune diseases like lupus and viral infections such as HIV can prompt the immune...
