Objective: To evaluate and compare the outcomes of patients with localised renal cell carcinoma (RCC) with and without sarcomatoid features and the impact of this on cancer recurrence and survival.
Material And Methods: The Canadian Kidney Cancer information system database was used to identify patients diagnosed with localised RCC between January 2011 and December 2022. Patients with pT1-T3, n Nx-N0N1, M0 stage and documented sarcomatoid status were included.
Objective: To compare the model-predicted benefits, harms, and cost-effectiveness of cytology, cotesting, and primary HPV screening in US women with HIV (WWH).
Design: We adapted a previously published Markov decision model to simulate a cohort of US WWH.
Setting: United States.
Background And Hypothesis: In the United States, women with schizophrenia face challenges in receiving gynecologic care, but little is known about how cervical cancer screening rates vary across time or states in a publicly insured population. We hypothesized that women Medicaid beneficiaries with schizophrenia would be less likely to receive cervical cancer screening across the United States compared with a control population, and that women with schizophrenia and other markers of vulnerability would be least likely to receive screening.
Study Design: This retrospective cohort study used US Medicaid administrative data from across 44 states between 2002 and 2012 and examined differences in cervical cancer screening test rates among 283 950 female Medicaid beneficiaries with schizophrenia and a frequency-matched control group without serious mental illness, matched on age and race/ethnicity.
Article Synopsis
- Implementation of primary HPV testing in the U.S. is slow, largely due to concerns about its sensitivity compared to cotesting methods, which combine HPV and cytology testing.
- A study of various populations showed that cotesting led to more laboratory tests and colposcopies than primary HPV testing, indicating a higher burden on healthcare resources.
- As the prevalence of cervical issues decreased, the detection of significant conditions through cotesting became less advantageous, suggesting that primary HPV testing may provide a better balance between benefits and risks than cotesting.
Objective: To identify how pediatric surgeons manage children with pneumonia and parapneumonic pleural effusion in Brazil.
Methods: An online cross-sectional survey with 27 questions was applied to pediatric surgeons in Brazil through the Brazilian Association of Pediatric Surgery. The questionnaire had questions about type of treatment, exams, hospital structure, and epidemiological data.
