Background: The routes to diagnosis and the time intervals along the diagnostic pathway affect cancer outcomes. Some data on routes to diagnosis and milestone dates can be extracted from registries or databases. When this data is incomplete, inaccurate or non-existing, other data sources are needed. This study investigates the agreement between multiple data sources on routes to diagnosis and milestone dates of cancer pathway.
Methods: Information on routes to diagnosis and milestone dates were compared across four data sources (cancer patients, general practitioners, cancer specialists and registries) for breast, colorectal, lung and ovarian cancers across the UK, Scandinavia, Canada and Australia. Agreement on routes to diagnosis and milestone dates was assessed by Kappa and AC1 coefficients and Lin's concordance correlation coefficient (CCC).
Results: 4502 patients were included in the analysis of routes to diagnosis. The agreement was almost perfect (kappa = 0.15-0.88, AC1 = 0.86-0.91) for breast cancer, substantial to almost perfect (kappa = 0.07-0.86, AC1 = 0.74-0.93) for colorectal and ovarian cancers, and substantial (kappa = 0.09-0.11, AC1 = 0.65-0.74) for lung cancer. 2287 patients were included in the analysis of milestone dates. The agreement was adequate for all cancer types (CCC = 0.88-0.99); highest agreement was seen for date of diagnosis (CCC = 0.94-0.99).
Conclusion: We found a reasonable agreement between patient/physician questionnaires and registry data for routes to diagnosis and milestone dates. The agreement on routes to diagnosis was generally higher for breast cancer than for colorectal, ovarian and lung cancers. Lower agreement was seen on date of first presentation to primary care and date of treatment initiation compared to date of diagnosis.

Pneumopericardium (PPC) is defined by the presence of gas in the pericardial cavity, often leading to cardiac tamponade and a high mortality rate. This report describes a case involving a 33-year-old man found deceased a few meters from a knife, his clothes intact, with no resuscitation attempt made. A knotted scarf was tightly fastened around his neck, without ligature mark.

Objectives: This case series describes adults with aquaporin 4 immunoglobulin G-seropositive (AQP4-IgG+) neuromyelitis optica spectrum disorder (NMOSD) who switched treatment from eculizumab to satralizumab.
Methods: Case information for patients with AQP4-IgG+ NMOSD who received satralizumab for ≥6 months was obtained from US healthcare providers from April 2022 to January 2024. Patient characteristics, examination findings, diagnostic test results, treatment response, and adverse events were recorded.

Background: Urolithiasis (kidney stone) is a common condition that often leads patients to urgent or emergency care services. Urinary calculi are generally found in the kidneys, ureters, or bladder. Urethral calculi are uncommon and can result from the migration of a calculus in the upper urinary tract or vesicle or may be primary of the urethra.

Objectives Although childhood cancer treatment has recently become centralized at specialized hospitals worldwide, the relationship between mortality ratios and living in rural areas or traveling long distances for treatment remains controversial. In the present study, we examined whether regional differences in patient mobility and mortality ratios exist in Japan.Methods We investigated 10,713 patients with cancer aged ≤18 years, diagnosed between 2016 and 2019, registered in the national cancer registry data.

Recently, 3-D porous architecture of the composites play a key role in cell proliferation, bone regeneration, and anticancer activities. The osteoinductive and osteoconductive properties of β-TCP allow for the complete repair of numerous bone defects. Herein, β-TCP was synthesized by wet chemical precipitation route, and their 3-D porous composites with HBO and Cu nanoparticles were prepared by the solid-state reaction method with improved mechanical and biological performances.
