OBJECTIVE
The authors investigated a new standardized technique for evaluating lumbar stability in lumbar lateral flexion-extension (LFE) radiographs. For patients with lumbar spondylolisthesis, a three-part fulcrum with a support platform that included a semiarc leaning tool with armrests, a lifting platform for height adjustment, and a base for stability were used. Standard functional radiographs were used for comparison to determine whether adequate flexion-extension was acquired through use of the fulcrum method.

METHODS
A total of 67 consecutive patients diagnosed with L4–5 degenerative lumbar spondylolisthesis were enrolled in the study. The authors analyzed LFE radiographs taken with the patient supported by a fulcrum (LFEF) and without a fulcrum. Sagittal translation (ST), segmental angulation (SA), posterior opening (PO), change in lumbar lordosis (CLL), and lumbar instability (LI) were measured for comparison using functional radiographs.

RESULTS
The average value of SA was 5.76° ± 3.72° in LFE and 9.96° ± 4.00° in LFEF radiographs, with a significant difference between them (p < 0.05). ST and PO were also significantly greater in LFEF than in LFE. The detection rate of instability was 10.4% in LFE and 31.3% in LFEF, and the difference was significant. The CLL was 27.31° ± 11.96° in LFE and 37.07° ± 12.963.16° in LFEF, with a significant difference between these values (p < 0.05).

CONCLUSIONS
Compared with traditional LFE radiographs, the LFEF radiographs significantly improved the detection rate of LI. In addition, this method may reduce patient discomfort during the process of obtaining radiographs.

Published: May 2022

The paper is devoted to the analysis of the knowledge transfer in two leading sectors of green economy in Ukraine – green energy and organic agriculture. Both sectors are of growing importance for the world economy, especially in the context of the need to fight global warming and to increase high quality food supply. Statistical data on functioning of these sectors in Ukraine shows that both sectors are developing very fast, both in terms of production outputs and number of the business.
That is why analysis is based on the patent data derived from the Espacenet database. The database provides information on patent according to CPC, which better meets the need of green economy analysis. We used OECD patent search strategy for the following areas: wind energy; solar thermal energy; hydroenergy; PV energy; fuel from waste; agriculture; nuclear energy; marine energy; bio-organic fraction processing; biofuels; hydrogen; solar thermal-PV hybrids; superconducting electric elements; geothermal energy.
The analysis shows that ties between different organizations, involved in development of green economy within the country are weak. Even in the most developed subsectors, namely wind, solar thermal energy and hydroenergy patent activity of commercial firms are extremely low.
This could be explained by technological backwardness, relatively small domestic markets for corresponding products and limited access to the foreign markets, existing of other channels for knowledge transfer. It was revealed paradox situation, when the number of scientific outputs related to green economy was growing up, while patent activity was declining. It means that current IPR and knowledge transfer system is not efficient in Ukraine and needs to be improved.
The paper is structures as follows. In the first part of the paper a brief description of green economy sectors of Ukraine is presented. It is followed by general situation with IPR in Ukraine. The third part is devoted to the analysis of green patenting in the country in recent years with the focus of networking between different actors. Conclusions contain final assessment of the situation and general recommendations for further innovation-based development of the green economy in Ukraine.

Published: May 2022

The article is devoted to analysis of the factors determining the feasibility of management accounting data applications in statistical research at micro level, which results will be used in elaborating and taking effective management decisions, as well as in the budget process for a given period of business operation. It is emphasized that the production efficiency can be achieved by the optimal use of resources given an acceptable level of risk. An analytical review of research works giving evidence of the need to use results of statistical research in business management was made. It showed that the necessity for analysis of the relationship between management accounting and creating databases for statistical research had not been clearly emphasized. Also, there has been no analysis of trends in creating a regulatory information framework at the national (cross-sectoral) level, which would have to consist of norms and standards of accounting and cost control in business entities. The assumption on a probable utilization of material resources in the shadow production due to the outdated regulatory framework is made.
Emphasis is placed on determining the fields of statistical research which results are going to be used in the business management system and evaluation of structural units in a business enterprise. The advantages of normative cost accounting and production costing for performance assessment and quick response on identified deficiencies in the management system are highlighted. It is argued that human resources constitute the main economic factor in the business operation process. The basic postulates of the national economy development are given, which have to frame the cost policy of business enterprises with taking into account results of statistical research. Problems related with applications of management accounting data in statistical research are outlined, which solutions can be subject of further research.

Background: To compare the corneal biomechanics of thin normal cornea (TNC) with thinnest corneal thickness (TCT) (≤500 µm), forme-fruste keratoconus (FFKC) and cornea after small incision lenticule extraction (Post-SMILE) had their central corneal thickness (CCT) matched by Corneal Visualization Scheimpflug Technology (Corvis ST).Methods: CCT were matched in 23 eyes with FFKC, 23 eyes by SMILE in 3 months post-operatively, and 23 TNC eyes. The differences in corneal biomechanics by Corvis ST among the three groups were compared.Results: There was no significant difference in CCT among the three groups, and the biomechanically corrected intraocular pressure (bIOP) did not differ significantly among the three groups (all p &gt; 0.05). There were significant differences in most DCR parameters between pre- and post-operatively (all p &lt; 0.05). Compared with TNC, the values of corneal deflection amplitude during the first applanation (A1DA), length at the first applanation (A1L), corneal deflection amplitude during the second applanation (A2DA), and maximum deformation amplitude (DA) decreased in 3 months after SMILE (all p &lt; 0.05), these values increased in the FFKC (all p &lt; 0.05).Conclusion: The majority of the DCR parameters were different among the three groups. The parameters A1DA, A1L, A2DA, and DA may be different between TNC and Post-SMILE, TNC and FFKC, and Post-SMILE and FFKC.

BackgroundThe diagnosis and treatment of mixed vaginitis are more complicated than single pathogenic infections, and there may be adverse reactions and several contraindications to conventional antibiotic therapy. Therefore, this study aimed to evaluate the preliminary effects of Fufang Furong Effervescent Suppository for the management of aerobic vaginitis (AV) mixed with bacterial vaginosis (BV) using Accurate 16S absolute quantification sequencing (Accu16S).MethodsIn the present randomized, blind, multi-center clinical trial, women (20 to 55 years) who had received a diagnosis of AV+BV were randomly assigned into clindamycin positive control (n = 41) and Fufang Furong Effervescent Suppository (n = 39) groups. The follow-up occurred in three time periods (V1: -2~0 days; V2: 15-17 days; V3: 40 ± 3 days). At each visit, two vaginal swabs, one for clinical evaluation and one for laboratory examination, were taken from each patient. The Nugent score, Donders’ score, drug-related complications, recurrence rates, and microecological changes of vaginal swabs were assessed in the time three periods.ResultsAt baseline, the two groups were similar in frequency of presentation with vaginal burning, odor, abnormal discharge, and itching. No meaningful differences in Nugent and Donders’ scores were detected between the two groups at stage V2 (Nugent: p = 0.67; Donders’: p = 0.85) and V3 (Nugent: p = 0.97; Donders: p = 0.55). The Furong group presented fewer complications compared to the Clindamycin group. However, this difference was not statistically significant (p = 0.15). Additionally, Accu16S indicated that the total abundance of bacteria in both groups sharply decreased in stage V2, but slightly increased in V3. In stage V3, the absolute abundance of Lactobacillus in the Furong group was considerably higher compared to untreated samples (p &lt; 0.05). On the other hand, no momentous increase was detected in the Clindamycin group (p &gt; 0.05).ConclusionFufang Furong Effervescent Suppository can be as effective as clindamycin cream in the management of AV+BV while may restore the vagina microecosystem better.
Modulation of Motor Cortex Activity After Intrathecal Baclofen Delivery in Chronic Thoracic Spinal Cord Injury
Authors: Štětkářová Ivana , Keller Jiří 
Published: May 2022

ObjectivesIntrathecal baclofen (ITB) is commonly used for reduction of spasticity in chronic spinal cord injury (SCI). Its clinical effect is well-known; however, exact mechanisms of long-term effect of continuous ITB administration (cITBa) on modulation of cortical processes have not been elucidated. The aim of this study was to evaluate changes in motor cortex activation for healthy upper limbs in comparison to impaired lower limbs by functional magnetic resonance imaging (fMRI).MethodsTen subjects (eight males, 20–69 years) with thoracic SCI presenting no voluntary movements of lower limbs (except one) were enrolled in the fMRI study. fMRI at 1.5T with a finger tapping paradigm and mental movement simulating foot flexion on the dominant side were performed before, 3 months, and 1 year after start of cITBa. fMRI data processing was carried out using FMRI Expert Analysis Tool (FEAT), part of FSL. A second-level analysis was carried out using FLAME stages 1 and 2. The level of spasticity was assessed with the Modified Ashworth scale (MAS).ResultsContinuous ITB significantly decreased limb spasticity in all the subjects (group MAS spasticity dropped from 3 to 0.3). The second-level analysis (Z &gt; 1.6, cluster significance threshold p =0.05) revealed increased activation of the primary sensorimotor cortex of the foot between baseline and 3 months, and 3 months and 1 year.ConclusionIncreased sensorimotor cortex activation with spasticity reduction after cITBa may reflect distant functional reorganization because of long-term mediated neuroplastic changes in the sensorimotor cortex. Better understanding of modulation of brain function in SCI after cITBa may influence the field of neurorehabilitation.

Background and PurposeCollateral flow in acute ischemic stroke is known as a predictor of treatment outcome and long-term prognosis. However, factors determining the initial collateral flow remain unclear. We investigated factors related to collateral flow in patients with acute ischemic stroke caused by large vessel occlusion (AIS-LVO) and further analyzed the results according to stroke etiology.MethodsThis was a retrospective study using prospective stroke registry data from a single university hospital from October 2014 to May 2021. AIS-LVO with middle cerebral artery M1 occlusion identified by pre-treatment multiphasic computed tomography angiography was included. Collateral flow score was graded on a 6-point ordinal scale according to pial arterial filling.ResultsA total of 74 patients [cardioembolism (CE): 57; large artery atherosclerosis (LAA): 17] was included. The mean age of all patients was 72.2 ± 11.7 years, and 37.8 % (n = 28) were men. Multivariate regression analysis showed that initial SBP [odds ratio (OR): 0.994; 95% confidence interval (CI): 0.990–0.998; p = 0.002] and stroke etiology (OR: 0.718; 95% CI: 0.548–0.940; p = 0.019) were independent factors of the collateral flow grade. Collateral flow grade was independently associated with initial SBP in the CE group (OR: 0.993; 95% CI: 0.989–0.998; p = 0.004) but not in the LAA group (OR: 0.992; 95% CI: 0.980–1.004; p = 0.218). Initial SBP was significantly correlated with NIHSS score in the CE group but not in the LAA group (r2= 0.091, p = 0.023; r2 = 0.043, p = 0.426, respectively).ConclusionsElevated initial SBP was associated with poor cerebral collateral flow and more severe symptoms in the CE group, but not in the LAA group in patients with AIS-LVO. These findings suggest differential effects of initial SBP elevation on collateral flow by stroke subtypes.
