Background: A passive dosimeter framework for the measurement of dose in carbon ion beams has yet to be characterized or implemented for regular use.
Purpose: This work determined the dose calculation correction factors for absorbed dose in thermoluminescent dosimeters (TLDs) in a therapeutic carbon ion beam. TLD could be a useful tool for remote audits, particularly in the context of clinical trials as new protocols are developed for carbon ion radiotherapy.
Study Question: How do endometriosis diagnoses and subtypes reported in administrative health data compare with surgically confirmed disease?
Summary Answer: For endometriosis diagnosis, we observed substantial agreement and high sensitivity and specificity between administrative health data-International Classification of Diseases (ICD) 9 codes-and surgically confirmed diagnoses among participants who underwent gynecologic laparoscopy or laparotomy.
What Is Known Already: Several studies have assessed the validity of self-reported endometriosis in comparison to medical record reporting, finding strong confirmation. We previously reported high inter- and intra-surgeon agreement for endometriosis diagnosis in the Endometriosis, Natural History, Diagnosis, and Outcomes (ENDO) Study.
Chimeric antigen receptor (CAR) T-cell therapy has transformed treatment of refractory B-cell malignancies; however, treatment puts patients at risk for side effects secondary to the amplified immune response it induces. Fulminant cerebral edema (FCE) is one of the rarest, yet most devastating side effects following CAR T-cell therapy. Due to this rarity, FCE has not been well characterized and the risk factors associated with its development are not fully understood.

- Alpha-gal syndrome is triggered by tick bites, leading to IgE responses against alpha-gal, a carbohydrate present in mammalian meat, causing delayed allergic reactions 2 to 6 hours after eating.
- Symptoms can include skin rashes, gastrointestinal issues, and occasionally severe anaphylaxis, often starting near the previous tick bite site.
- Diagnosis involves monitoring symptom timing and prior tick bite history, with treatment focusing on immediate care during allergic reactions and long-term management requiring a strict meat-free diet.
