Subtyping primary aldosteronism by inconclusive adrenal vein sampling: A derivation and validation study in a tertiary centre.

Objective: Indices based on aldosterone/cortisol (A/C) concentration in the successfully cannulated adrenal vein (AV) and in the inferior vena cava (IVC) (AV/IVC) appear to be possible markers to verify the subtype of primary aldosteronism (PA) in the case of inconclusive results of adrenal vein sampling (AVS). The variability of results in previous studies encouraged us to calculate AV/IVC and adrenal A/C cutoff values that could predict the aetiology of PA.

Methods: This retrospective study included 96 patients who underwent AVS due to PA between 2015 and 2020.

The impact of the COVID-19 pandemic on resident physicians: A cross-sectional study.

Background: COVID-19 presents a threat to the mental health of the medical staff working with COVID-19 patients.

Objective: To investigate the impact of working during the COVID-19 pandemic on resident physicians.

Methods: The study was conducted via anonymous online survey and included resident physicians.

Dropout during a driving simulator study: A survival analysis.

Introduction: Simulator sickness is the occurrence of motion-sickness like symptoms that can occur during use of simulators and virtual reality technologies. This study investigated individual factors that contributed to simulator sickness and dropout while using a desktop driving simulator.

Method: Eighty-eight older adult drivers (mean age 72.

[Diagnosis of cystic echinococcosis in faeces scattered in areas of Puna and Quebrada. Province of Jujuy, Argentina].

Echinococcosis is a parasitic disease common in livestock, caused by the cestode Echinococcus granulosus, the dog being the principal definitive host. The province of Jujuy is an endemic area located in the Northwest of Argentina. Due to the restricted ecological conditions of Quebrada and Puna, the most important activity of the population is formal cattle pastoralism and transhumance, especially of sheep and camelids.

Cognitive and visual predictors of UFOV performance in older adults.

Eighty two community dwelling older adults (52 females) aged 62-92 years (mean=75) completed a battery of cognitive and visual tests selected to assess functions relevant to driving performance. These were visual acuity, contrast sensitivity, general mental competence (Mini Mental State Examination, MMSE), processing speed (Inspection Time, IT), crowding across the visual field (Proficiency of Peripheral Vision Processing, ProPerVis) and change detection (DriverScan). These six tasks provided predictor variables for performance on the Useful Field of View test (UFOV), a well validated test of fitness to drive that includes subtests for (i) processing speed; (ii) divided attention; and (iii) selective attention.
