ABSTRACT

OBJECTIVE: Aim: To research how the future dentists’ professional self-determination (reflects the cognitive-reflexive component of higher medical education applicants’ readiness to use digital technologies in their professional activities) develops within the formation of information technology competence in the modern realities of Ukraine.

PATIENTS AND METHODS: Materials and Methods: The author’s questionnaire consisted of 15 questions. The questionnaire surveys covered 98 future dentists who studied ‘Medical Informatics’ and ‘Information Technology in Dentistry’ at the Ivano-Frankivsk National Medical University in the September-December 2017-2018 and September- December 2022-2023 academic years. The research results were assessed according to the algorithm described. The research used such methods as analysis, synthesis, comparison, concretisation, systematisation, and generalisation, as well as methods of mathematical statistics for evaluating data, namely correlation analysis, Kolmogorov-Smirnov test, Cronbach’s alpha, Fisher’s test (F-test of equality of variances), Student’s t-test and ranking.

RESULTS: Results: The research found positive dynamics of the professional self-determination levels (in 2022 compared to 2017, the low level decreased by 20.5%, the satisfactory level – by 19.0%, the average level increased by 20.6%, the high level – by 18.9%) and their quality, which within the research increased by 39.5%.

CONCLUSION: Conclusions: By forming information technology competence, future dentists changing the priorities of professional self-determination in the modern realities of Ukraine and acquiring readiness (within the cognitive-reflexive component) to use digital technologies in professional activities.

ABSTRACT

OBJECTIVE: Aim: To evaluate the functional connection and the bioelectrical state of the m.masseter and m. sternocleidomastoid using functional tests before and after treatment.

PATIENTS AND METHODS: Materials and Methods: The sample consisted of 21 individuals with temporomandibular joint dysfunction. Examinations were carried out before and after treatment using repositioning splint therapy and in seated/standing positions.

RESULTS: Results: M. masseter – p=0.072 before treatment and p=0.821 after treatment. Symmetry is also maintained after treatment. After treatment, a significant difference is noted at the level of significance p<0.001 for the right chewing muscle. In seated and standing positions before treatment did not reveal a statistically significant difference (p=0.07, p=0.143) and after (p=0.272, p=0.623).M. sternocleidomastoid- p<0.001 when comparing right and left sides. After treatment, there was no difference between the right and left sides (p=0.169). No statistical difference was found when assessing indicators separately for the right and left muscles in seated and standing positions (p=0.304, p=0.611, p=0.089, p=0.869). When comparing the bioelectric potentials of the right muscle before, after treatment, a statistically significant difference was found p=0.001.

CONCLUSION: Conclusions: Biostatistical analysis of the indicators of bioelectrical activity of m. masseter and sternocleidomastoid indicates no changes in muscle microvolt indicators with changes in body position in patients. However, repositioning splint therapy is associated with reduced muscle tone in initially more spasmodic muscles. It is worth noting that the symmetry of interaction between muscles improves.

ABSTRACT

OBJECTIVE: Aim: To study and analyze the attitude of women of reproductive age to the integrated gynecological care provision by family physicians, their readiness to receive some gynecological services from family physicians, as well as to analyze the level of women’s support and readiness for the integrated provision of gynecological care depending on age and level of education.

PATIENTS AND METHODS: Materials and Methods: For the survey, anonymous questionnaires containing questions on the attitude of women of reproductive age to the integrated provision of certain types of gynecological care by family physicians were developed. 181 women from the Kyiv region took part in the survey.

RESULTS: Results: Support of more than 80% of respondents regarding the integrated gynecological care provision by family physicians received the following questions: counseling on the prevention of sexually transmitted infections and human immunodeficiency virus/acquired immunodeficiency syndrome (HIV/AIDS) (92,3%); counseling on family planning and prevention of unwanted pregnancy (83,4%); counseling on the use of various methods of contraception (82,3%); examination and palpation of mammary glands (80,1%); referral of women to a higher level of obstetric and gynecological care (if necessary (86,2%).

CONCLUSION: Conclusions: The majority of respondents (67,4%) are ready or better ready than not ready to receive certain types of gynecological care services from family physicians. Almost the same percentage ratio (more than 60%) of women of each age group and all levels of education are ready or better ready than not ready to receive gynecological care services, which they supported, from family physicians.

ABSTRACT

OBJECTIVE: Aim: Dynamic comparison of the lower limbs length, depending on the type of sport, followed by the construction of a mathematical model for predicting sports abilities.

PATIENTS AND METHODS: Materials and Methods: The comparison of the lower limbs length in dynamics was carried out on 132 students of higher education institutions of Bukovyna. While the primary study was carried out during September-October 2021, next study of these same students was conducted in September-October 2022. The main group consists of 92 (69.7%) students, the control group – 40 (30.30%) students aged 16 to 18 years. All students underwent an anthropometric study (determination of the length of the lower limbs) according to the method of P.P. Shaparenka. The comparesment of anthropometric parameters in the main group depending on the type of sport used the Kruskel-Wallis test (non-parametric analysis of variance) in order to identify a reliable difference in the average indicators of the respondents depending on the type of sport (the median of the distribution was considered as a measure of central tendency). In order to establish which pairs of age groups had a statistical difference in the medians, the Conover-Iman test was used. A paired t-test (t-test of paired samples) was performed to compare the length of the respondents’ lower limbs during the first measurement and again one year later. Statistical analysis of the obtained data was performed using the licensed RStudio program.

RESULTS: Results: The distribution of the length of the right lower limb of the respondents of the main group by measurement shows that the average value of the length of the right lower limb has changed: a significant difference in the length of the right lower limb was found between the first (M = 88.812, SD = 5.287) and the second (M = 89.377, SD = 5.347) measurements; t (68) = -5.223, p < 0.001. The distribution of the length of the left lower limb shows that the average value of the length of the left lower limb has changed also: a significant difference in the length of the left lower limb was found between the first (M = 88.667, SD = 5.266) and the second (M = 89.435, SD = 5.309) measurements; t (68) = -8.289, p < 0.001.

CONCLUSION: Conclusions: In order to dynamically compare the length of the lower limbs for comprehensive control and selection of promising students in football, volleyball, handball and basketball, a mathematical model was derived for predicting the length of the lower limbs, in corresponding sports: right lower limb y = 0.506 x and left y = 0.507x, where y – is the length of the left lower limb, x – is the height. The coefficient of determination is 99.8%. A significant predictor for the length of both lower limbs is the height.

ABSTRACT

OBJECTIVE: Aim: This study aimed to assess the effectiveness of the developed algorithm for treatment and prevention measures aimed at eliminating clinical manifestations of bruxism in young people.

PATIENTS AND METHODS: Materials and Methods: A cohort of 377 individuals aged 25 to 44 years underwent examination. Based on identified etiological factors, three distinct groups were delineated. Treatment and preventive strategies were then implemented and evaluated. Tailored treatment algorithms were devised for each group: Group one received selective grinding of supracontacts (up to 0.5-0.75 mm) and treatment for orthodontic issues utilizing removable and fixed orthodontic structures. Group two underwent finger self-massage of masticatory muscles, fabrication of biting dental splints, and anti-inflammatory drug therapy. Group three received sedative drug therapy in conjunction with psychiatric consultation, based on indications. Treatment efficacy was assessed 12 months post-initiation. Statistical analyses were conducted using Statistica 10.0 (StatSoft, Inc., USA) and Microsoft Office Excel 2010.

RESULTS: Results: In cases where orthodontic pathology and supracontacts predominated (r=0.99, p<0.05), employing selective grinding and orthodontic treatment according to specific indications yielded significant efficacy. This approach resulted in a notable reduction in bruxism severity, corroborated by occludogram results 12 months post-treatment initiation. Notably, 90.0% of occludogram indicators fell within the 90-100% range, accompanied by a decrease in the BruxChecker abrasion facets area (p<0.05). Further, there was a substantial enhancement in occlusal contacts (Ck=0.68, Ck =0.71, Ck =0.93). In instances where TMJ pathology predominated with high reliability (r=0.98, p<0.05), effective normalization of masticatory muscle tone and alleviation of temporomandibular joint issues were observed. After 12 months, palpation revealed minimal tenderness in specific muscle areas and normalization of electromyography readings from initial indicators (p<0.05). Moreover, when the psycho-emotional factor primarily contributed to bruxism etiology (r=0.97, p<0.05), medical intervention proved effective. This approach led to bruxism disappearance and normalization of the psycho-emotional state within 12 months (p<0.05).

CONCLUSION: Conclusions: The conducted studies provide high-confidence evidence of the effectiveness of bruxism treatment when diagnosing the prevailing etiological factor and targeting its specific impact, leading to the normalization of all other factors, a reduction in bruxism intensity, and its complete disappearance.

ABSTRACT

Point scanning retinal imaging modalities, including confocal scanning light ophthalmoscopy (cSLO) and optical coherence tomography, suffer from fixational motion artifacts. Fixation targets, though effective at reducing eye motion, are infeasible in some applications (e.g., handheld devices) due to their bulk and complexity. Here, we report on a cSLO device that scans the retina in a spiral pattern under pseudo-visible illumination, thus collecting image data while simultaneously projecting, into the subject’s vision, the image of a bullseye, which acts as a virtual fixation target. An imaging study of 14 young adult volunteers was conducted to compare the fixational performance of this technique to that of raster scanning, with and without a discrete inline fixation target. Image registration was used to quantify subject eye motion; a strip-wise registration method was used for raster scans, and a novel, to the best of our knowledge, ring-based method was used for spiral scans. Results indicate a statistically significant reduction in eye motion by the use of spiral scanning as compared to raster scanning without a fixation target.

ABSTRACT

Under spatially incoherent illumination, time-domain full-field optical coherence tomography (FFOCT) offers the possibility to achieve in vivo retinal imaging at cellular resolution over a wide field of view. Such performance is possible, albeit there is the presence of ocular aberrations even without the use of classical adaptive optics. While the effect of aberrations in FFOCT has been debated these past years, mostly on low-order and static aberrations, we present, for the first time to our knowledge, a method enabling a quantitative study of the effect of statistically representative static and dynamic ocular aberrations on FFOCT image metrics, such as SNR, resolution, and image similarity. While we show that ocular aberrations can decrease FFOCT SNR and resolution by up to 14 dB and fivefold, we take advantage of such quantification to discuss different possible compromises between performance gain and adaptive optics complexity and speed, to optimize both sensor-based and sensorless FFOCT high-resolution retinal imaging.

ABSTRACT

BACKGROUND: Nirmatrelvir/ritonavir (NMV/r) is an oral antiviral drug used to treat mild-to-moderate coronavirus disease 2019 (COVID-19) in patients aged 12 years or older at high risk of progression to severe disease (eg, hospitalization and death). Despite being the preferred option for outpatient treatment in the majority of countries worldwide, NMV/r is currently underutilized in real-world clinical practice.

AREAS OF UNCERTAINTY: As numerous real-world studies have described patient outcomes following treatment with NMV/r, this systematic literature review provides a comprehensive summary of evidence on NMV/r effectiveness against hospitalization and mortality further organized by clinically meaningful categories, such as acute versus longer-term follow-up, age, underlying health conditions, and vaccination status, to help inform health care decision making.

DATA SOURCES: We searched Embase and PubMed (December 22, 2021-March 31, 2023) and congress abstracts (December 1, 2021-December 31, 2022) for reports describing NMV/r effectiveness.

THERAPEUTIC ADVANCES: In total, 18 real-world studies met final selection criteria. The evidence showed that NMV/r significantly reduced postinfection risk of all-cause and COVID-19-related hospitalization and mortality in both acute (≤30 days) (21%-92%) and longer-term (>30 days) (1%-61%) follow-up. The reduction in postinfection risk was higher when treatment was received within 5 days of symptom onset. Real-world effectiveness of NMV/r treatment was observed regardless of age, underlying high-risk conditions, and vaccination status.

CONCLUSION: The systematic literature review findings demonstrated the effectiveness of NMV/r against hospitalization and mortality during the Omicron period among individuals at high risk of progression to severe COVID-19 disease.

ABSTRACT

BACKGROUND: Sex differences (SDs) in pharmacology of cardiovascular (CV) drugs have been described previously; however, paradoxically, there are scarce recommendations in therapy based on these differences. It is of utmost importance to identify whether these SDs determine a modified clinical response and the potential practical implications for this, to provide a base for personalized medicine.

AREA OF UNCERTAINTY: The aim of this article was to outline the most important pharmacological drivers of cardiovascular drugs that differ between women and men, along with their implications and challenges in clinical practice.

DATA SOURCES: A detailed assessment of English-written resources reflecting SDs impact in CV drug pharmacology was performed using PubMed and Embase databases.

RESULTS: Despite large variations in CV drug pharmacokinetics and pharmacodynamics in individuals, correcting for height, weight, surface area, and body composition compensate for most “sex-dependent” differences. In addition, individual, cultural, and social factors significantly impact disease management in women versus men. Gender-biased prescribing patterns and gender-dependent adherence to therapy also influence outcomes. The development of sex-specific guidelines requires that they should reflect the SDs implications for the management of a disease and that the evidence should be carefully evaluated as to whether there is an adequate representation of both sexes and whether sex-disaggregated data are reported.

CONCLUSIONS: Pharmacological drivers are under the influence of an impressive number of differences between women and men. However, to establish their significance in clinical practice, an adequate representation of women in studies and the reporting of distinct results is mandatory.
