Likelihood of survival of coronavirus in a respiratory droplet deposited on a solid surface
https://aip.scitation.org/doi/10.1063/5.0012009

We predict and analyze the drying time of respiratory droplets from a COVID-19 infected subject, which is a crucial time to infect another subject. Drying of the droplet is predicted by using a diffusion-limited evaporation model for a sessile droplet placed on a partially wetted surface with a pinned contact line. The variation in droplet volume, contact angle, ambient temperature, and humidit...

Imaging in Parkinson’s disease
https://www.ncbi.nlm.nih.gov/pmc/articles/PMC6280219/
Clinical Medicine;

The clinical presentation of Parkinson’s disease (PD) is heterogeneous and overlaps with other conditions, including the parkinsonian variant of multiple system atrophy (MSA-P), progressive supranuclear palsy (PSP) and essential tremor.

Risk factors of levodopa-induced dyskinesia in Parkinson’s disease: results from the PPMI cohort
https://www.nature.com/articles/s41531-018-0069-x
NPJ Parkinson's Disease;

Levodopa-induced dyskinesias (LID) negatively impact on the quality of life of patients with Parkinson’s disease (PD). We assessed the risk factors for LID in a cohort of de-novo PD patients enrolled in the Parkinson’s Progression Markers Initiative (PPMI). This retrospective cohort study included all PD patients enrolled in the PPMI cohort. Main outcome was the incidence rate of dyskinesia, de...

Cynthia X. Ma, MD, PhD, on Breast Cancer: Neoadjuvant Endocrine Treatment for ER-Positive, HER2-Negative Disease
https://ascopost.com/videos/asco20-virtual-scientific-program/cynthia-ma-on-neoadjuvant-endocrine-treatment-for-er-positive-her2-negative-breast-cancer/

May 31st, 2020 - Cynthia X. Ma, MD, PhD, of Washington University, discusses results from the ALTERNATE trial, which showed neither fulvestrant nor fulvestrant plus anastrozole significantly improved endocrine-sensitive disease rate compared with anastrozole alone in postmenopausal patients with locally advanced estrogen receptor–positive, HER2-negative breast cancer (Abstract 504).

AFP

The adult well-male examination should provide evidence-based guidance toward the promotion of optimal health and well-being. The medical history should focus on tobacco and alcohol use, risk of human immunodeficiency virus and other sexually transmitted infections, and diet and exercise habits. The physical examination should include blood pressure screening, and height and weight measurements...

Persistent cannabis use as an independent risk factor for violent behaviors in patients with schizophrenia
https://www.nature.com/articles/s41537-020-0104-x

Although recent studies have shown a moderately strong association between cannabis use and violence among people with severe mental disorders, the direction of this association has not been investigated prospectively in a population with schizophrenia. Therefore, this study aims to determine, using cross-lag models, whether a temporal relationship between cumulative cannabis use and violence e...
