[A portrait of a doctor with Parkinson's disease].

In a number of causes of Parkinson's disease (PD), occupation is periodically mentioned as a possible risk factor. However, a look at the complex impact of external factors on people of certain professions and the expansion of the area of risk factors in a rapidly changing world leads to the emergence of new studies. There is an assumption that the risk of developing PD is increased in doctors due to long-term exposure to stress.

Triple combination of vemurafenib, cobimetinib, and atezolizumab in real clinical practice in the Russian Federation: results of the A1 cohort of the ISABELLA study.

Background: Among several treatment options for BRAF-mutant metastatic melanoma, a combination of BRAF inhibitor, MEK inhibitor, and anti-PDL1 antibody seems to be a new emergent approach recently registered in the Russian Federation. It is still not clear which patient population benefits more from this simultaneous use of three drugs instead of its sequencing.

Aim: This study aimed to evaluate patients' characteristics treated in real practice in 14 Russian regions by triple combination and to analyze their outcomes depending on biomarkers (PD-L1 expression).

[Sarcopenia as a non-motor symptom of Parkinson's disease].

Sarcopenia is a progressive generalized skeletal muscle disease that is accompanied by an accelerated loss of muscle mass and function, affecting the quality of life and the ability to perform self-care. The prevalence of sarcopenia in the world today ranges from 10 to 25%, which represents a certain danger as it is a prognostic factor for possible injury and increased disability in the elderly population. Sarcopenia often accompanies a large number of different diseases, including neurodegenerative ones, so it is actively studied in this category of patients, for example, as one of the early symptoms of Parkinson's disease (PD).
