AI Article Synopsis

  • Taiwan has one of the highest rates of upper tract urothelial cancer (UTUC) in the world, especially among women, but there has been no comprehensive long-term study on this issue.
  • A nationwide analysis of UTUC incidence from 1985 to 2019 used data from the Taiwan Cancer Registry, breaking down the population into nine age groups to assess age-specific trends.
  • The findings revealed a notable increase in renal pelvis cancer incidence, with women experiencing a higher rise than men, particularly in older age groups and among younger cohorts compared to older ones.

Article Abstract

Background: Taiwan has one of the highest incidences of upper tract urothelial cancer (UTUC) worldwide, especially in women; however, no nationwide, long-term follow-up study has evaluated this.

Methods: We investigated the incidence of UTUC in Taiwan using data from the national population-based Taiwan Cancer Registry database (1985-2019). We divided the birth cohort into nine 5-year age groups and calculated the age-specific incidence for these groups according to the corresponding birth years.

Results: The average annual percent change in the incidence of renal pelvis cancer from 1985 to 2019 showed sex-specific differences, with 3.5% and 5.3% increases in the incidences in men and women, respectively. The age-specific incidence rate for renal pelvis cancer among women showed a gradual increase in the group with older women as well as an increase over time in each age group. The results of a birth cohort analysis revealed that younger cohorts had higher incidence rates of renal pelvis cancer than older cohorts did.

Conclusion: We demonstrated that the incidence of UTUC is unusually high among older Taiwanese women and that younger cohorts have a high risk of UTUC than older cohorts.

Background: The safety of the COVID-19 inactivated vaccine on pregnancy outcomes in couples undergoing assisted reproductive technology remains uncertain due to limited and speculative evidence. Existing studies primarily focus on the vaccination status of females, with scant information available regarding the vaccination status of male partners. Moreover, there is minimal research tracking live birth outcomes.

Background: Preimplantation genetic testing for chromosomal structural rearrangements (PGT-SR) has been widely utilized to select euploid embryos in patients carrying balanced chromosomal rearrangements (BCRs) by chromosome copy number analysis. However, reliable and extensively validated PGT-SR methods for selecting embryos without BCRs in large-cohort studies are lacking.

Methods: In this prospective, multicenter, cohort study, carriers with BCRs undergoing PGT-SR were recruited across 12 academic fertility centers within China.

Background: Around one in three pregnant women undergoes induction of labour in the United Kingdom, usually preceded by in-hospital cervical ripening to soften and open the cervix.

Objectives: This study set out to determine whether cervical ripening at home is within an acceptable safety margin of cervical ripening in hospital, is effective, acceptable and cost-effective from both National Health Service and service user perspectives.

Design: The CHOICE study comprised a prospective multicentre observational cohort study using routinely collected data (CHOICE cohort), a process evaluation comprising a survey and nested case studies (qCHOICE) and a cost-effectiveness analysis.
