Herein, we report a KIO-catalyzed oxidative coupling of thiols to their corresponding disulfides in water, in a short time and at ambient temperature. The reaction has a broad scope and exhibits good functional group tolerance, resulting in the desired products in excellent yields. This approach allows the reuse of the reaction system in multiple cycles and scale-up.

However, it is unclear if there is a relationship between dysarthria and the severity or duration of the disease.
Objective: Describe the speech pattern in MS, correlate with clinical data, and compare with controls.

Purpose: To assess the association between acute disease severity and 1-year quality of life in patients discharged after hospitalisation due to coronavirus disease 2019 (COVID-19).
Methods: We conducted a prospective cohort study nested in 5 randomised clinical trials between March 2020 and March 2022 at 84 sites in Brazil. Adult post-hospitalisation COVID-19 patients were followed for 1 year.
Objective: To describe the speech pattern of patients with hereditary Spastic Paraplegia type 4 (SPG4) and correlated it with their clinical data.
Methods: Cross-sectional study was carried out in two university hospitals in Brazil. Two groups participated in the study: the case group (n = 28) with a confirmed genetic diagnosis for SPG4 and a control group (n = 17) matched for sex and age.
Unlabelled: Although it is predominantly a muscular disease, impairments in the central nervous system in patients with facioscapulohumeral muscular dystrophy (FSHD) have been described in the literature.
Objective: To describe the cognitive profile of patients with FSHD and to correlate the impairments found with clinical variables and quality of life.
Methods: Cross-sectional and case-control study that evaluated FSHD patients using a series of cognitive assessments (Mini-Mental State Examination - MMSE, Montreal Cognitive Assessment - MoCA, verbal fluency with phonological restriction - FAS, categorical verbal fluency - FAS-cat, trail-making test - TMT, and Rey's Verbal Auditory Learning Test); a neurological severity scale (Gardner-Medwin-Walton - GMWS); and a quality of life measurement tool (Medical Outcomes Study 36-Item Short-Form Health Survey).
