Шкала оценки сопутствующих заболеваний у ареактивных пациентов (CoCoS): лингвокультурная адаптация русскоязычной версии (сообщение)
Identification of complications and control of comorbidities are essential in monitoring the patients with chronic disorders of consciousness and predicting their outcomes. The researchers of the Department of Biotechnological and Applied Clinical Sciences of the University of L'Aquila (Italy) developed the Comorbidities Coma Scale (CoCoS) for a comprehensive assessment of such patients. Lack of an officially validated version of the scale hampers its use in Russia, while using versions which have not been completely validated prevents clinicians from obtaining reliable results when examining patients with chronic disorders of consciousness. Aim. To develop the official Russian language version of the Comorbidities Coma Scale, considering various linguistic and cultural parameters, as a part of the 1st stage of the validation study. Material and methods. The first stage of validation was completed: direct and reverse translation of the scale was performed by two independent medical translators. The translated version was assessed by an expert board including an expert translator, neurologists, and critical care specialists. Pilot test and two meetings of the expert board, before and after testing, were arranged to assess the results and approve the final Russian version of the scale. Results. During the first meeting of the expert board, corrections were made in the Russian language version of the scale in terms of language and cultural adaptation. Pilot testing was carried out based on the inclusion and exclusion criteria. The researchers had no difficulties in understanding and interpreting the instructions for the scale. The second meeting of the expert board was held thereupon, and the final version of the Russian language version of the scale was adopted, which is available on the website of the Center for Validation of Health Status Questionnaires and Scales of the Research Center of Neurology. Conclusion. The first stage of validation, i. e., linguistic and cultural adaptation, was carried out at the Research Center of Neurology (Moscow, Russia). For the first time, the Russian version of the scale for assessing comorbidities in patients with chronic disorders of consciousness was presented and approved for the practical use. The future publications will address the psychometric results of the scale such as sensitivity, validity, reliability. Выявление осложнений и контроль над течением сопутствующих заболеваний является важнейшим этапом в отслеживании динамики и прогнозе исходов у пациентов с хроническими нарушениями сознания. Для проведения оценки состояния у данной категории пациентов сотрудниками департамента биотехнологических и прикладных клинических наук университета L'Aquila (Италия) была разработана шкала — Comorbidities Coma Scale (CoCoS). Отсутствие официально валидированной версии данной шкалы затрудняет ее применение в России, а использование версий, не прошедших все необходимые этапы валидации, препятствует получению достоверных результатов при обследовании пациентов с хроническими нарушениями сознания. Цель. Разработка официальной русскоязычной версии Шкалы оценки сопутствующих заболеваний у ареактивных пациентов с учетом языковых и культурных особенностей ее пользователей в рамках проведения 1-го этапа валидационного исследования. Материал и методы. Письменное разрешение на адаптацию шкалы CoCoS было получено сотрудниками группы валидации международных шкал и опросников Научного центра неврологии (ФГБНУ НЦН, г. Москва, Россия) у разработчика оригинальной версии Francesca Pistoia. Провели первый этап валидации: выполнен прямой и обратный перевод шкалы двумя независимыми медицинскими переводчиками. Произведена оценка разработанной версии экспертной комиссией с участием переводчика-эксперта, неврологов и анестезиологов-реаниматологов. Провели пилотное тестирование на 15 пациентах с диагнозом хронического нарушения сознания и два заседания экспертной комиссии до и после тестирования для оценки результатов и утверждения окончательной русскоязычной версии шкалы. Результаты. В ходе первого заседания экспертной комиссии внесли поправки в русскоязычную версию шкалы в рамках языковой и культурной адаптации: были изменены единицы измерения лабораторных показателей с мг/дл на ммоль/л в 7-м и 14-м пунктах (оценка гликемии и концентрации креатинина, соответственно). Изменен термин «надаортальные сосуды» на «брахиоцефальные артерии» в 10-м пункте, сопоставлены предложенные варианты повреждения мягких тканей со стадиями развития пролежней согласно NPUAP — EPUAP [18] в 21-м пункте, добавлен параметр индекс массы тела (ИМТ) для оценки выраженности недостаточности питания. В ходе пилотного тестирования с учетом критериев включения и исключения сложностей при понимании и интерпретации инструкций шкалы у исследователей не возникло. По итогам состоялось второе заседание экспертной комиссии, на котором приняли окончательный вариант русскоязычной версии шкалы. Он доступен для ознакомления на сайте группы валидациимеждународных шкал и опросников ФГБНУ НЦН https://www.neurology.ru/reabilitaciya/centr-validacii-mezhdunarodnyh-shkal-i-oprosnikov, а также по QR-коду. Заключение. На базе ФГБНУ НЦН выполнили первый этап валидации — лингвокультурную адаптацию. Впервые представили и рекомендовали к использованию русскоязычную версию Шкалы оценки сопутствующих заболеваний у ареактивных пациентов. В последующих публикациях будут представлены результаты оценки психометрических свойств (чувствительность, валидность, надежность) русскоязычной версии данной шкалы

Density functional theory study of the carbon chains C
A theoretical study of CnX, CnX+ and CnX- (X = O
and Se; n = 1-10) clusters is carried out employing the density functional
theory and the B3LYP functional. All species are fully optimized using the
basis set 6-31G(d) for all atoms and further, single-point computations are
done using the B3LYP/aug-cc-pVTZ level. Molecular properties such as
equilibrium parameters, dipole moment, infrared vibrational frequencies,
Raman activities and rotational constant are predicted. The computations
indicate that the equilibrium structures are either linear or quasi-linear.
We report the different forms of electron affinities, ionization energy,
atomization energy and binding energy of the CnO and CnSe chains.
The results indicate parity effect is very apparent for electron affinity,
ionization energy, and binding energy but the effect is less pronounced for
atomization energy. The n-even linear chains have larger ionization energy
and atomization energy than the n-odd ones but this effect is reversed for
electron affinity. The findings from this work are critically discussed and
they are very similar to those obtained previously for the hetero-atom doped
carbon chains. This research indicates that n-odd carbon chains are more
stable than n-even and this is the trend for the chalcogens carbon chains
Stannylenes: Structures, Electron Affinities, Ionization Energies, and Singlet–Triplet Gaps of SnX<sub>2</sub>/SnXY and XSnR/SnR<sub>2</sub>/RSnR′ Species (X; Y = H, F, Cl, Br, I, and R; R′ = CH<sub>3</sub>, SiH<sub>3</sub>, GeH<sub>3</sub>, SnH<sub>3</sub>)
Systematic computational studies of stannylene derivatives
SnX<sub>2</sub>/SnXY and XSnR/SnR<sub>2</sub>/RSnR′ were carried
out
using density functional theory. The basis sets used for H, F, Cl,
Br, C, Si, and Ge atoms are of double-ζ plus polarization quality
with additional s- and p-type diffuse functions, denoted DZP++. For
the iodine and tin atoms, the Stuttgart-Dresden basis sets, with relativistic
small-core effective core potentials (ECP), are used. All geometries
are fully optimized with three functionals (BHLYP, BLYP, and B3LYP).
Harmonic vibrational wavenumber analyses are performed to evaluate
zero-point energy corrections and to determine the nature of the stationary
points located. Predicted are four types of neutral-anion separations,
plus adiabatic ionization energies (<i>E</i><sub>IE</sub>) and singlet–triplet energy gaps (Δ<i>E</i><sub>S‑T</sub>). The dependence of all three energetic properties
upon choice of substituent is remarkably strong. The EA<sub>ad(ZPVE)</sub> values (eV) obtained with the B3LYP functional range from 0.70 eV
[Sn(CH<sub>3</sub>)<sub>2</sub>] to 2.36 eV [SnI<sub>2</sub>]. The
computed <i>E</i><sub>IE</sub> values lie between 7.33 eV
[Sn(SnH<sub>3</sub>)<sub>2</sub>] and 11.15 eV [SnF<sub>2</sub>],
while the singlet–triplet splittings range from 0.60 eV [Sn(SnH<sub>3</sub>)<sub>2</sub>] to 3.40 eV [SnF<sub>2</sub>]. The geometries
and energetics compare satisfactorily with the few available experiments,
while most of these species are investigated for the first time. Some
unusual structures are encountered for the SnXI<sup>+</sup> (X = F,
Cl, and Br) cations. The structural parameters and energetics are
discussed and compared with the carbene, silylene, and germylene analogues
Dicyanogermylenes: A Tale of Isomers and Interconversions
A systematic investigation is carried out using the B3LYP,
BLYP,
and BHLYP functionals and MP2 level of theory to characterize the
low-lying electronic singlet and triplet GeC<sub>2</sub>N<sub>2</sub> isomers. The basis sets used are of double-ζ plus polarization
quality with additional s- and p-type diffuse functions, DZP++. Three
bent isomers Ge(CN)<sub>2</sub>, CNGeCN, and Ge(NC)<sub>2</sub> are
located on the singlet and triplet potential energy surfaces. In visualizing
the reaction pathways for the singlet isomerization of the bent isomers,
two three-membered [Ge, C, N] cyclic systems, with exocyclic −C–CN
and −C–NC bonding, appear on the energy surface.
Four types of electron affinities reported are: the adiabatic electron
affinity, the zero-point vibrationally corrected electron affinity,
the vertical electron affinity, and the vertical detachment energy
of the anion. The ionization energies and singlet–triplet gaps
for all isomers are also reported. The energetic ordering (kcal mol<sup>–1</sup>) (B3LYP) with zero-point vibrational energy corrections
for the singlet ground state isomers follows: Ge(CN)<sub>2</sub> (global
minimum) < CNGeCN (2.3) < Ge(NC)<sub>2</sub> (3.3) < Cyc_exo_CCN
(15.3) < Cyc_exo_CNC (30.6). All the bent and cyclic isomers are
found to be below the dissociation limit to Ge (<sup>3</sup>P) + C<sub>2</sub>N<sub>2</sub> (<sup>1</sup>Σ<sub>g</sub>). The rate
constants for all interconversions are evaluated using transition
state theory
