AI Article Synopsis

  • In 1976, Air France's Concordes logged 2,642 hours of flight time over 772 commercial flights to Rio de Janeiro, Caracas, and Washington, measuring cosmic radiation dosage during these trips.
  • The average cosmic radiation dose was recorded at 0.99 mrems/h, with Washington flights showing a higher average of 1.49 mrem/h compared to 0.78 mrem/h on the Rio and Caracas routes.
  • Overall, the radiation exposure for Concorde passengers and crew was significantly low, well below the public safety limit of 500 mrems per year.

Article Abstract

In 1976, Air France's Concordes operated 2,642 h of flight time during 772 commercial flights to Rio de Janeiro, Caracas, and Washington. The cosmic radiation dose equivalent rate was measured during each of these flights. The average amount recorded was 0.99 mrems/h. A distinction must be made between the high latitudes (Washington route), on which an average dose equivalent rate of 1.49 mrem/h was recorded, and low latitudes (Rio de Janeiro and Caracas routes), on which the average dose equivalent rate was only 0.78 mrems/h. These figures show that 1976 Concorde passengers and crews were exposed to very low quantities of radiation--very much lower than the maximum value recommended for the general public, which is 500 mrems per year.

Background: The aim of this study was to compare the efficacy outcomes of the traditional Judkins left and right catheters with those of the recently introduced Tiger catheter in female participants aged 65 years and older who underwent transradial coronary angiography.

Methods: A cohort of 160 female patients aged 65 and older who were scheduled for coronary angiography (CAG) were divided into two groups according to the use of Tiger (n = 80) or Judkins (n = 80) catheters for radial angiography at a ratio of 1:1, respectively. We analyzed the effectiveness of the Tiger and Judkins catheters, the incidence of catheter failure, contrast volume, CAG time, fluoroscopy time, dose-area product (in mGy/cm), and the occurrence of radial spasm.

The treatment regimen for [Lu]Lu-prostate-specific membrane antigen (PSMA) 617 therapy follows that of chemotherapy: 6 administrations of a fixed activity, each separated by 6 wk. Mathematic modeling can be used to test the hypothesis that the current treatment regimen for a radiopharmaceutical modality is suboptimal. A mathematic model was developed to describe tumor growth during [Lu]Lu-PSMA therapy.

For patients with nonmetastatic soft tissue sarcoma (STS) who are at high risk of local recurrence, the standard of care for limb-conserving local management is combined radiotherapy and surgery. Radiotherapy for STS entails 5 weeks of conventionally fractionated radiotherapy (25 × 2 Gy) preoperatively or 6 or more weeks postoperatively. There is growing interest in the use of preoperative hypofractionated regimes, viz.

Background: Frontotemporal dementia (FTD) presents with a change in personality, behaviour and language and is the second most common cause of young-onset dementia after Alzheimer's disease. Loss of function mutations in GRN, encoding progranulin (PGRN), causes FTD in the heterozygous state, accounting for 5-10% of all FTD cases. PGRN is essential for normal lysosomal function and neuronal survival.

Background: The emergence of new SARS-CoV-2 variants poses a new challenge for the treatment of immunocompromised patients against COVID-19. In this context, high titer COVID-19 Convalescent Plasma (CCP) is one of the few available therapeutics for these patients. We have revisited the selection of CCP samples and its efficacy against Omicron XBB.
