New-onset psychosis following COVID-19 vaccination: a systematic review.

Background: The emergence of a new coronavirus strain caused the COVID-19 pandemic. While vaccines effectively control the infection, it's important to acknowledge the potential for side effects, including rare cases like psychosis, which may increase with the rising number of vaccinations.

Objectives: Our systematic review aimed to examine cases of new-onset psychosis following COVID-19 vaccination.

Bacterial etiology of acute otitis media and characterization of pneumococcal serotypes and genotypes among children in Moscow, Russia.

Background: We aimed to describe bacterial etiology of acute otitis media (AOM) and characterize resistance, serotypes and genotype profiles of AOM-causing pneumococci recovered in Moscow children.

Methods: Children with AOM and an available middle ear fluid specimen were prospectively enrolled in this study. Streptococcus pneumoniae, Streptococcus pyogenes, Haemophilus influenzae and Moraxella catarrhalis were considered as true otopathogens.

Polyfunctional compounds containing the 4,6-dialkoxy-7-arylthioheptene moiety as synthetically useful intermediates. The course of lewis acid-induced transformations.

Data on the selectivity of the Lewis acids induced transformations of the title compounds are presented, and the routes leading to formation of products containing either cyclohexane or 1,3-diene units are described.

[Adaptation to physical and psychoemotional loads and mental work capacity in patients with neurocirculatory dystonia].

Mental performance and adaptation to exercise and psychoemotional loads were studied in 119 patients with neurocirculatory asthenia (NCA), 245 patients with chronic focal infection (CFI) of the upper airways, and 247 NCA patients with CFI. Exercise tolerance was measured at spiroergometry, intellectual and psychoemotional adaptation were assessed by shifts in attention and fatigue while working with Schulte tables under conditions of time limits and the results criticism, vegetative reactivity was tested with insulin and epinephrine, variation pulsograms recorded vegetative provision of physical, intellectual and psychoemotional activity. Abnormalities in mental performance and the above adaptation related to clinical presentation of NCA and CFI as well as to vegetative regulation were registered in NCA+CFI patients.
