ABSTRACT

In the context of forecasted decreasing of natality, actuality of studying its causes for organizational decision-making increases. The purpose of the study was to determine factors affecting reproductive behavior of women aged 40-45 years residing in areas with different natality levels in 2020-2021. The cohort, analytical, sociological methods were applied. The results of study demonstrated that in areas with high natality level most of urban women with higher education and high income resides in conditions of dormitory or mortgage flat and working in profile of their specialty. They are characterized by belated marriage that results in postponed child-bearing. The areas with low natality are characterized by dwelling of rural women with secondary or secondary specialized education. They reside in their own homes and work in other occupations than their specialty. The analysis of social status of women of different age groups will permit more selective approach in developing measures of increasing natality in modern conditions.

ABSTRACT

Ovarian hyperstimulation syndrome (OHSS) is the most severe and life-threatening complication of assisted reproductive technologies (ART). OHSS is based on an excessive ovarian response to ovarian stimulation; however, the pathogenesis has not been fully understood yet. The most serious complications of OHSS are thromboembolic complications and ovarian torsion. The current study describes the risk factors for the development of ovarian hyperstimulation syndrome and proposes a method for specific prediction of this syndrome. This study was designed to investigate 671 therapeutic cycles in the IVF program during 2009-2018. All patients were divided into two groups. Group one (n=56) included women who developed OHSS during the IVF procedure. Group two (n=615) consisted of women who did not have this complication during the IVF procedure. All the observation and examination outcomes were entered into a specially developed questionnaire, and then into a Microsoft Excel spreadsheet. The data were processed by variable statistics using Statistica 10.0. Analyzing of the recorded data revealed that the rate of OHSS was higher in the group of younger women, aged 30.76±3.67 years, in comparison with those aged 32.78±4.40 years in the group of patients without OHSS (p<0.05). The analysis of the initial phase of the reproductive system has confirmed that the group of patients with OHSS had a higher level of prolactin, 462.84±191.56 mIU/L in comparison with 363.43±187.84 mIU/L, which corresponded to the group of women without OHSS (p<0.05). In our results, 7.15±1.04% of cases with OHSS had obesity, while of the patients from the group without OHSS suffered from it (p<0.05). OHSS is the most severe iatrogenic complication of ART, therefore it is extremely important to consider its risk factors and take timely preventive measures. This study has established a high relationship between the studied risk factors and ovarian hyperstimulation syndrome and proposed a model for predicting this syndrome.

ABSTRACT

This is the first study of the effect of topiramate on linguistic behavior and verbal recall using a computational linguistics system for automated language and speech analysis to detect and quantify drug-induced changes in speech recorded during discourse-level tasks. Healthy volunteers were administered a single, 100-mg oral dose of topiramate in two double-blind, randomized, placebo-controlled, crossover studies. Subjects' topiramate plasma levels ranged from 0.23 to 2.81 µg/mL. We found a significant association between topiramate levels and impairment on measures of verbal fluency elicited during a picture description task, correct number of words recalled on a paragraph recall test, and reaction time recorded during a working memory task. Using the tools of clinical pharmacology and computational linguistics, we elucidated the relationship between the determinants of a drug's disposition as reflected in plasma concentrations and their impact on cognitive functioning as reflected in spoken language discourse.

ABSTRACT

The main objective of this study was to investigate the feasibility of using PharmGKB, a pharmacogenomic database, as a source of training data in combination with text of MEDLINE abstracts for a text mining approach to identification of potential gene targets for pathway-driven pharmacogenomics research. We used the manually curated relations between drugs and genes in PharmGKB database to train a support vector machine predictive model and applied this model prospectively to MEDLINE abstracts. The gene targets suggested by this approach were subsequently manually reviewed. Our quantitative analysis showed that a support vector machine classifiers trained on MEDLINE abstracts with single words (unigrams) used as features and PharmGKB relations used for supervision, achieve an overall sensitivity of 85% and specificity of 69%. The subsequent qualitative analysis showed that gene targets "suggested" by the automatic classifier were not anticipated by expert reviewers but were subsequently found to be relevant to the three drugs that were investigated: carbamazepine, lamivudine and zidovudine. Our results show that this approach is not only feasible but may also find new gene targets not identifiable by other methods thus making it a valuable tool for pathway-driven pharmacogenomics research.

ABSTRACT

BACKGROUND: EHR clinical document synthesis by clinicians may be time-consuming and error-prone due to the complex organization of narratives, excessive redundancy within documents, and, at times, inadvertent proliferation of data inconsistencies. Development of EHR systems that are easily adaptable to the user's work processes requires research into visualization techniques that can optimize information synthesis at the point of care. OBJECTIVE: To evaluate the effect of a prototype visualization tool for clinically relevant new information on clinicians' synthesis of EHR clinical documents and to understand how the tool may support future designs of clinical document user interfaces. METHODS: A mixed methods approach to analyze the impact of the visualization tool was used with a sample of eight medical interns as they synthesized EHR clinical documents to accomplish a set of four pre-formed clinical scenarios using a think-aloud protocol. RESULTS: Differences in the missing (unretrieved) patient information (2.3±1.2 [with the visualization tool] vs. 6.8±1.2 [without the visualization tool], p = 0.08) and accurate inferences (1.3±0.3 vs 2.3±0.3, p = 0.09) were not statistically significant but suggest some improvement with the new information visualization tool. Despite the non-significant difference in total times to task completion (43±4 mins vs 36±4 mins, p = 0.35) we observed shorter times for two scenarios with the visualization tool, suggesting that the time-saving benefits may be more evident with certain clinical processes. Other observed effects of the tool include more intuitive navigation between patient details and increased efforts towards methodical synthesis of clinical documents. CONCLUSION: Our study provides some evidence that new information visualization in clinical notes may positively influence synthesis of patient information from EHR clinical documents. Our findings provide groundwork towards a more effective display of EHR clinical documents using advanced visualization applications.

ABSTRACT

The paper presents the results of a 5-year follow-up of simulative manifestations of tuberculosis at penitentiaries. The high rate of use of penitentiaries as an object of these manifestations has been established, predominantly relapse aggravation of process activity being observed when treatment is continued. The causes of simulative manifestations are diverse; along with a qualitative physical examination, they should be borne in mind by a phthisiatrician in order to make a timely diagnosis.

ABSTRACT

We explore the use of FrameNet (FN) frames and their frame elements to represent content from the International Classification of Functioning, Disability and Health (ICF) Self-Care chapter. Terms were extracted from the ICF and mapped to FN frames. The mappings were validated by an expert. FN provided relevant and nearly complete coverage of ICF terms, suggesting FN may be an important resource to leverage for semantic language processing and knowledge representation in this domain.

ABSTRACT

This paper deals with the investigation of the brain organization of verbal creativity. Psychological tasks were designed in accordance with two main strategies used by volunteers in solving creative tasks. Regional cerebral blood flow (rCBF) was measured with positron emission tomography (PET) when performing two types of creative tasks in two groups of subjects, each type of the task organizing the creativity process in its own way. Valuable brain correlates of creativity were revealed in the left parieto-temporal regions (Brodmann areas 39 and 40).

ABSTRACT

Molecular and electronic structures for four p-carborane derivatives were studied in the context of their liquid crystalline properties. Thus molecular and crystal structures of diheptyl and diheptynyl derivatives of 10- and 12-vertex bi-p-carboranes were determined by X-ray crystallography and compared to the results of ab initio calculations at the HF/6-31G level of theory. Experimentally observed significant positional disorder of one of the substituents in the 10-vertex derivatives, 2[2]a and 2[2]b, was related to conformational properties of the alkyl-carborane bond. Experimental and theoretical studies of the electronic structures were conducted for the four compounds using UV and NMR spectroscopies. The nature of the unique long wavelength absorption band at 232 nm in the diheptynyl derivative 2[2]b was explained using INDO/2//HF/6-31G analysis. The complete assignment of the (13)C signals was accomplished using a long-range coupling technique and was supported by the calculated (HF/6-31G) isotropic shielding tensors. Analysis of absorption spectra, NMR substituent effects, and trends in bond lengths shows generally strong cage-acetylene electronic interactions for the 10-vertex p-carborane, while the 12-vertex p-carborane remains largely electronically isolated. Ab initio calculations revealed that 12-vertex p-carborane has significantly larger electronic polarizability and quadrupole moments than the 10-vertex analogues, which are larger than those for bicyclo[2.2.2]octane compounds. All these results on packing, conformational, and electronic properties form the basis for the discussion of thermal behavior of the four carborane compounds, bicyclo[2.2.2]octane analogues, and some related compounds.

ABSTRACT

Previous positron emission tomography (PET) and functional magnetic resonance imaging (fMRI) studies show that during attentive listening, processing of phonetic information is associated with higher activity in the left auditory cortex than in the right auditory cortex while the opposite is true for musical information. The present PET study determined whether automatically activated neural mechanisms for phonetic and musical information are lateralized. To this end, subjects engaged in a visual word classification task were presented with phonetic sound sequences consisting of frequent (P = 0.8) and infrequent (P = 0.2) phonemes and with musical sound sequences consisting of frequent (P = 0.8) and infrequent (P = 0.2) chords. The phonemes and chords were matched in spectral complexity as well as in the magnitude of frequency difference between the frequent and infrequent sounds (/e/ vs. /o/; A major vs. A minor). In addition, control sequences, consisting of either frequent (/e/; A major) or infrequent sounds (/o/; A minor) were employed in separate blocks. When sound sequences consisted of intermixed frequent and infrequent sounds, automatic phonetic processing was lateralized to the left hemisphere and musical to the right hemisphere. This lateralization, however, did not occur in control blocks with one type of sound (frequent or infrequent). The data thus indicate that automatic activation of lateralized neuronal circuits requires sound comparison based on short-term sound representations.

ABSTRACT

A triphenylsilyl group is used as an auxiliary in the synthesis of heterodisubstituted p-carboranes via triphenylsilyl-p-carborane (1). The preparation of 1 is statistical, but with recovery of the starting p-carborane, the effective conversion to 1 is about 90%. Carborane 1 has been easily converted to its lithium and copper derivatives, which were reacted with a range of electrophiles including alkyl halides: an aryl iodide, an acetylene bromide, and a sulfenyl chloride. The derivatives of 1 are crystalline and UV active, which facilitates their isolation and purification. The Ph(3)Si group is efficiently removed with fluoride to give monosubstituted p-carboranes I, which upon further nucleophilic substitution yield p-carboranes II. The yields of heterodisubstituted products II are higher than for direct, "statistical" syntheses. For example, 12-pentyl-1, 12-dicarba-closo-dodecaborane-1-carboxylic acid was synthesized from p-carborane via 1 in 62% overall yield, a considerable improvement over the 44% yield obtained by direct methods.
