Objective: Thymidine-dependent small-colony variants (TD-SCVs) of Staphylococcus aureus are being isolated with increasing frequency from patients with cystic fibrosis (CF). The aim of this study was to evaluate the relationship between TD-SCV isolation and pulmonary function in patients with CF, as well as to determine whether the emergence of TD-SCVs was associated with trimethoprim-sulfamethoxazole (TMP-SMX) use and with coinfection with other microorganisms.
Methods: This was a retrospective case-control study including patients with CF who visited the Clinical Hospital Complex of the Federal University of Paraná, in Curitiba, Brazil, between 2013 and 2022.
The Diósi-Penrose model states that the wave function collapse ending a quantum superposition occurs due to the instability of coexisting gravitational potentials created by distinct geometric conformations of the system in different states. The Heisenberg time-energy principle can be invoked to estimate the collapse time for the energy associated with this instability, the gravitational self-energy. This paper develops atomistic models to calculate the Diósi-Penrose collapse time.

Methods: a census, descriptive, sectional study, with 46 nurse residents from three public hospitals in Rio de Janeiro. Data collection took place between August 2020 and January 2021, using a sociodemographic questionnaire, including a question about the use of spirituality/ religiosity to deal with work situations.
Objective: To analyze the results of auditory assessment in standard (SA) and extended high-frequency (EHF) audiometry, associating the findings with sudden tinnitus and mental health of patients with unilateral sudden sensorineural hearing loss (SSNHL).
Study Design: Prospective, cohort study.
Setting: Outpatient otology clinic in a tertiary care hospital.
Article Synopsis
- The scientists studied new silver compounds that might help fight cancer, especially in cases where other drugs don’t work.
- They used various techniques to analyze these compounds and understand how they work against different cancer cells.
- The results showed that one type of silver compound was very effective against a certain cancer type and caused cells to die in a unique way, which could make it a good treatment option for difficult cancers.
