Optical quantum communication technologies are making the prospect of unconditionally secure and efficient information transfer a reality. The possibility of generating and reliably detecting quantum states of light, with the further need of increasing the private data-rate is where most research efforts are focusing. The physical concept of entanglement is a solution guaranteeing the highest degree of security in device-independent schemes, yet its implementation and preservation over long communication links is hard to achieve.

Primary sclerosing cholangitis (PSC) is a risk factor for cholangiocarcinoma. When a child is diagnosed with both PSC and inflammatory bowel disease (IBD), evidence-based information on counseling families and risk management of developing cholangiocarcinoma is limited. In this case series (PubMed/collaborators), we included patients with PSC-IBD who developed cholangiocarcinoma and contacted authors to determine an event curve specifying the time between the second diagnosis (IBD or PSC) and a diagnosis of cholangiocarcinoma.

Importance: Communicating clearly about who is included in a population group is a critical element to effective dissemination and knowledge transfer. This narrative review highlights the inconsistency as it relates to communicating about individuals with intellectual disability (ID) and developmental disability (DD).

Observations: There is enormous variability in the use of definitions and abbreviations in the field of intellectual disability and developmental disabilities.

Article Synopsis
  • Patients with primary sclerosing cholangitis (PSC) and inflammatory bowel disease (IBD) have a significant risk of developing colorectal cancer, and there's no consensus on the best surveillance methods.
  • A study analyzed 91 patients with PSC and IBD over ten years to evaluate how effective chromoendoscopy and high-definition endoscopy were in detecting neoplastic lesions during regular check-ups.
  • Results showed that chromoendoscopy greatly increased the detection rate of neoplasia (by 5.58 times), while high-definition endoscopy also improved detection, but its significance diminished when factoring in chromoendoscopy.

Purpose: To identify structures at risk during proximal adductor longus repair and to report observed distances between these structures and the adductor longus (AL) footprint.

Methods: Eight hemipelves from fresh cadaver whole-body specimens were dissected using a previously established surgical approach. The tendinous attachment of the AL was scored into the underlying bone and the footprint size was measured in millimeters.
