[Perioperative complications in surgery for craniosynostosis in children: a systematic review and meta-analysis].

Objective: To study the structure, incidence and risk factors of perioperative complications in children with craniosynostosis (CS).

Material And Methods: A systematic searching of data was performed for analysis of perioperative complications and adverse events following surgical correction of CS in patients younger 24 months.

Results.

Prospective assessment of surgical stress response in patients with craniosynostosis: comparison of clinical and laboratory data.

Background: Highly traumatic surgical correction of craniosynostosis (CS) is usually followed by severe postoperative period and high risk of complications. Surgical stress response (SSR) is an important and often neglected cause of severe early postoperative period.

Objective: To compare clinical and laboratory parameters of SSR in children who underwent various surgeries for CS.

[Prospective analysis of inflammatory markers and perioperative clinical data in children with craniosynostosis undergoing reconstructive surgery].

Background: Craniosynostosis (CS) is a group of skull malformations manifested by congenital absence or premature closure of cranial sutures. Reconstructive surgery in the second half of life is traditional approach for CS. The issues of surgical stress response after reconstructive surgery for CS in children are still unclear.

[Reset osmostat syndrome - when hyponatremia become «a normal»: diagnostics, case report].

Reset osmostat syndrome (ROS) is characterized by a change of normal plasma osmolality threshold (decrease or increase), which leads to chronic dysnatremia (hypo- or hypernatremia). We have described a clinical case of ROS and chronic hyponatremia in a patient with chordoid glioma of the III ventricle. It is known that the patient had previously been diagnosed with hyponatremia (131-134 mmol/l).

[Delta-He a new biomarker for a surgical clinic].

Background: Delta-He the difference between hemoglobin content in reticulocytes and erytrocytes is a relatively new laboratory indicator that is easily measured in everyday practice. This parameter is directly related to iron bioavailability for hemoglobin synthesis and can reflect various conditions accompanied by cytokine expression including systemic inflammation.

Objective: To analyze the prospects for practical application of hemoglobin delta in assessment of neurosurgical patients throughout in-hospital treatment.

Nanoribbon-Based Electronic Detection of a Glioma-Associated Circular miRNA.

Nanoribbon chips, based on "silicon-on-insulator" structures (SOI-NR chips), have been fabricated. These SOI-NR chips, whose surface was sensitized with covalently immobilized oligonucleotide molecular probes (oDNA probes), have been employed for the nanoribbon biosensor-based detection of a circular ribonucleic acid (circRNA) molecular marker of glioma in humans. The nucleotide sequence of the oDNA probes was complimentary to the sequence of the target oDNA.

Micro-Raman Characterization of Structural Features of High-k Stack Layer of SOI Nanowire Chip, Designed to Detect Circular RNA Associated with the Development of Glioma.

The application of micro-Raman spectroscopy was used for characterization of structural features of the high-k stack (h-k) layer of "silicon-on-insulator" (SOI) nanowire (NW) chip (h-k-SOI-NW chip), including AlO and HfO in various combinations after heat treatment from 425 to 1000 °C. After that, the NW structures h-k-SOI-NW chip was created using gas plasma etching optical lithography. The stability of the signals from the monocrine phase of HfO was shown.

Raman Spectroscopy-Based Quality Control of "Silicon-On-Insulator" Nanowire Chips for the Detection of Brain Cancer-Associated MicroRNA in Plasma.

Application of micro-Raman spectroscopy for the monitoring of quality of nanowire sensor chips fabrication has been demonstrated. Nanowire chips have been fabricated on the basis of «silicon-on-insulator» (SOI) structures (SOI-NW chips). The fabrication of SOI-NW chips was performed by optical litography with gas-phase etching.

Community screening for hepatitis C virus infection in a low-prevalence population.

Background: Age cohort screening for hepatitis C virus (HCV) might be an effective strategy if the majority of undiagnosed cases are concentrated in a particular age group. The objective of this study was to determine HCV prevalence in different age cohorts of the general population in the Central European part of Russia and second, to assess feasibility of HCV antigen testing for community screening programs.

Methods: Sera from 2027 volunteers were tested for anti-HCV (Architect Anti-HCV, Abbott Laboratories).
