Purpose of the study to carry out a comparative analysis of the state of the zonular fibers before and after surgery on UBM between femtolaser assisted and classical ultrasound cataract removal. Material and methods. 19 patients (38 eyes) with age-related cataracts. 22 eyes were with pseudo-exfoliative syndrome. All patients were examined with grade 1 lens subluxation. The first group of 19 eyes underwent cataract femto-phacoemulsification. The second group included 19 eyes without using a femtolaser. The state of the fibers was determined on the UBM on the fifth day after the operation at the end of antibiotic therapy. Results. The data showed the presence of a statistically significant difference between the group with femto-assistance and the group without it. In the first group, UBM analysis showed that the state of the zonular fibers remained in the same state in 16 of 19 eyes. In the second group, 11 of 19 eyes required ring implantation with suturing to the sclera and 3 required IOL implantation with seamless fixation to the sclera and vitrectomy. Conclusions. The appropriate path to surgery depends on the most accurate objective assessment of the condition of the lens ligaments, since the position of the IOL is one of the main factors for a good result expected by the patient after surgery. Reducing the «trauma» of the eye with lens surgery has been a key success factor and femtolaser guidance provides valuable assistance in obtaining it. Key words: lens subluxation, femtosecond laser, UBM.

Introduction. An osteopathic examination determines the rate, the amplitude and the strength of the main rhythms (cardiac, respiratory and cranial). However, there are relatively few studies in the available literature dedicated to the influence of osteopathic correction (OC) on the characteristics of these rhythms.Goal of research — to study the influence of OC on the rate characteristics of various rhythms of the human body.Materials and methods. 88 adult osteopathic patients aged from 18 to 81 years were examined, among them 30 men and 58 women. All patients received general osteopathic examination. The rate of the cranial rhythm (RCR), respiratory rate (RR) heart rate (HR), the mobility of the nervous processes (MNP) and the connective tissue mobility (CTM) were assessed before and after the OC session.Results. Since age varied greatly in the examined group, a correlation analysis of age-related changes of the assessed rhythms was carried out. Only the CTM correlated with age (r=–0,28; p<0,05) in a statistically significant way. The rank dispersion analysis of Kruskal–Wallis also showed statistically significant difference in this indicator in different age groups (p=0,043). With the increase of years, the CTM decreases gradually. After the OC, the CTM, increased in a statistically significant way (p<0,0001). The RCR varied from 5 to 12 cycles/min in the examined group, which corresponded to the norm. After the OC, the RCR has increased in a statistically significant way (p<0,0001), the MNP has also increased (p<0,0001). The initial heart rate in the subjects varied from 56 to 94 beats/min, and in 15 % it exceeded the norm. After the OC the heart rate corresponded to the norm in all patients. The heart rate and the respiratory rate significantly decreased after the OC (р<0,0001).Conclusion. The described biorhythm changes after the OC session may be indicative of the improvement of the nervous regulation, of the normalization of the autonomic balance, of the improvement of the biomechanical properties of body tissues and of the increase of their mobility. The assessed parameters can be measured quickly without any additional equipment and can be used in order to study the results of the OC.

Background. The purpose of this observational case series study was to investigate the role of 25 MHz ultrasound biomicroscopy (UBM) in detecting subluxated lenses and compare it with 50 MHz UBM. Methods. 45 patients (49 eyes) with suspected subluxation of the lens and 20 normal volunteers (40 eyes) were included. Different cross-sectional images of the lens position were captured in axial and longitudinal scanning modes using 25 and 50 MHz UBM. The main outcome measurements included the linear distance between the lens equator and ciliary process, the difference value (D-value) between the same cross section of the above bilateral linear distance in the normal and the subluxated subjects, the diagnostic accuracy, and the testing times obtained with 25 and 50 MHz UBM. Results. The position of the lens on axial sections could be clearly shown by using 25 MHz UBM. The D-value of the subluxated eyes was 1-2 mm longer than that of the normal ones. There was a statistically significant difference between 25 and 50 MHz UBM in showing subluxation of the lens, the testing time was significantly faster (2.0 min versus 7.5 min), and the diagnostic accuracy was much higher (98.0% versus 71.4%) with 25 versus 50 MHz UBM. Fifteen eyes with slightly subluxated lens were detected by 25 MHz UBM, and only one eye with slight lens subluxation was detected by 50 MHz UBM. Conclusions. The results indicated that 25 MHz UBM has a greater diagnostic value than 50 MHz UBM in verifying the status of the lens subluxation and can provide reliable and quantitative imaging evidence for clinical use. This trial is registered with ChiCTR–DOD –15007603.

This study compared the exergame beach volleyball’s acute effects on state anxiety level in single vs. multiplayer mode in adult men. Sixty adult men (age: 21.98 [4.58] years, body mass: 75.40 [15.70] kg, height: 1.77 [0.09] m, and body mass index: 24.19 [5.44] kg/m2; data are expressed as median [interquartile range]) were assigned to play exergame of beach volleyball in single- or multiplayer mode for approximately 30 min using the Xbox 360 Kinect®. The state anxiety level was evaluated before and after the intervention. There was no significant difference in the state anxiety levels after an exergame session between the single and multiplayer modes (p-value = 0.407, effect size (rB) = −0.12, defined as small). Furthermore, there was no significant difference in the state anxiety levels before and after an exergame session in single-player mode (p-value = 0.516, effect size (d) = 0.14, defined as trivial) and multiplayer mode (p-value = 0.053, rB = 0.43, defined as medium). In conclusion, state anxiety level after exergame beach volleyball did not differ between the single and multiplayer modes in adult men.

This study aims to determine how public participation in the Pilkada before the Covid-19 Pandemic and during the Covid-19 Pandemic. Quoting Jean Jacques Rousseau's theory, democracy is a stage or a process that must be passed by a country in order to gain prosperity. One of the democracies in Indonesia is the Pilkada which is held in each region. However, since the Covid-19 Pandemic which has an impact on various sectors, it has made a significant difference to the implementation of Pilkada in each region. Changes in implementation conditions which of course have an impact on community participation are interesting things to study. In addition, based on the analysis of the VOSViewer software, research on comparative analysis of the Pilkada before and during the Covid-19 Pandemic has not been much researched. This research is a descriptive qualitative study with the help of data analysis software NVIVO 12 Plus. The results of this study indicate that there is a decrease in community participation in participating in Pildaka, both during the campaign period or at the time of voting at the TPS. Another thing that is the difference between Pilkada contestation before and after the Covid-19 Pandemic is the phenomenon of a single candidate in several regions in Indonesia, which rarely happened before this Pandemic

Precipitation is the main source for replenishing groundwater stored in aquifers for a myriad of beneficial purposes, especially in arid and semi-arid regions. A significant portion of the municipal and agricultural water demand is satisfied through groundwater withdrawals in Texas. These withdrawals have to be monitored and regulated to be in balance with the recharge amount from precipitation in order to ensure water security. The main goal of this study is to understand the spatio-temporal variability of precipitation in the 21st century using high spatial resolution stage-IV radar data over the state of Texas and examine some climatic controls behind this variability. The results will shed light on the trends of precipitation and hence will contribute to improving water resources management strategies and policies. Pettit’s test and Standard Normal Homogeneity Test (SNHT), tools for detecting change-point in the monthly precipitation, suggested change-points have occurred across the state around the years 2013 and 2014. The test for the homogeneity of the data before and after 2013 revealed that, in over 64% of the state, the precipitation means were significantly different. The Panhandle region (northern part) is the only part of the state that did not show a significant difference in the mean precipitation before and after 2013. Theil-Sen’s slope test, Correlated Seasonal Mann-Kendall Test, and Cox and Stuart Trend Test all indicated that there were no significant trends in the monthly precipitation after 2013 in over 98% of the area of the state. Texas precipitation was found to be influenced significantly by the El Niño-Southern Oscillation (ENSO) and the Pacific Decadal Oscillation (PDO). A significant correlation in more than 82% and 60% of the state was found with ENSO at two-month and with PDO at four-month lag, respectively.

Objective This study aimed to compare the level of anxiety in pregnant women who were admitted to our institute before and after confirmation of COVID-19 outbreak have reached Turkey. Methods One-hundred and fifty consecutive pregnant women admitted to our institute following the emergence of the global COVID-19 outbreak (Group 1) and 150 age-matched pregnant women who were admitted to our institute for delivery following the confirmation of COVID-19 outbreak have reached Turkey (Group 2) were enrolled in this study. All patients were asked to fill out the State and Trait Anxiety Inventory (STAI). Results STAI-Trait scores, which reflect long term anxiety levels were similar in subjects admitted to our institute for delivery before the COVID-19 outbreak in Turkey compared to those admitted after COVID-19 outbreak (42.5±5.8 vs. 42.2±3.2, respectively; p=0.487). However, there was a significant difference in STAI-State scores, indicating state anxiety, between subjects admitted to our institute for delivery before and after confirmation of COVID-19 outbreak in Turkey (44.6±5.3 vs. 42.9±5.1, respectively; p=0.05). Conclusion Pregnant women admitted to our institute for delivery subsequent to the announcement of first COVID-19 case and declaration of the state of alarm have higher levels of state anxiety compared to those admitted before the establishment of first COVID-19 cases and containment measures.

Chronic heart failure relates to the priorities of national health systems in most countries due to the high prevalence, steady increase in the number of new cases in all countries, frequent repeated hospitalizations, poor quality of treatment, high levels of disability and mortality, and increased treatment costs. An important multidisciplinary task is to study the state of the brain in the background of chronic cardiac pathology, which is associated with a violation of the pumping function of the heart and central hemodynamics. The purpose of the study was to investigate the state of the cognitive and psychoemotional sphere in patients with chronic cerebral ischemia and chronic heart failure with a preserved and reduced release fraction. In a comparative analysis in patients with chronic cerebral ischemia and chronic heart failure with a preserved and reduced emission fraction, a statistically significant difference was not found. Direct correlation dependence with complaints of memory impairment (r = 0.34), anxiety manifestations (r = 0.44), depression (r = 0.42). According to the study, cognitive impairment was observed in 95.3% of patients in group 1 and in 71.1% of patients in group 2. Dementia of light severity was found in patients with 1 group in 18.6% and in patients with 2 groups in 11.1%. Data from a neuropsychological study showed cognitive safety in 4.6% of patients in group I and 28.8% in group 2, which were characterized by mild modal-nonspecific mantle disorders. Premedicinal cognitive disorders were observed in group 1 in 33 (76.7%) patients and in 27 (60%) patients in group 2 (Table 1). There was a statistically significant difference between the groups p = 0.009 (p <0.05) and the direct correlation between MMSE and age (r = 0.63), quality of life (r = 0.31), complaints when considering deterioration of memory (r = 0.39).

We performed a prospective cohort comparative analysis of simple trapezectomy and trapezectomy with pyrocarbon interposition in 38 consecutive patients with trapeziometacarpal joint osteoarthrosis. Patients were assessed preoperatively, at six and 12 months postoperatively using subjective and objective tools. Subjective assessment was performed using the Quick Disabilities of the Arm, Shoulder, and Hand questionnaire and the visual analogue score. Objective assessment was performed with grip strength measurements. At each time interval, statistical differences were sought between the two subgroups. No significant difference between the two subgroups was noted at any time interval on subjective or objective assessment. A significant difference (p < 0.05) was found on comparing the respective preoperative and 12-month subjective scores in both subgroups. Of the pyrocarbon subgroup seven had related complications. We suggest that pyrocarbon interposition does not significantly improve postoperative function, requires a longer operation with a high postoperative risk of pyrocarbon displacement and need for revision surgery.

Coastal spaces (including land areas and sea areas) in Japan are managed by the state or local governments, and their private use by individuals was not allowed unless contribution to public interest was ensured. Since the Designated Manager System for public facilities was established in 2003, management of an increasing number of public facilities based on the Local Autonomy Laws has been consigned to private sectors (called “designated managers”) nominated through the decisions of the local councils, rather than to public bodies based on the conventional “Management Commission System.” Regarding marinas including land areas and sea areas, we conducted a comparative analysis of their convenience, comfort, serviceability, and so forth before and after introduction of the Designated Manager System from the viewpoint of marina users to discuss how the private sector should manage coastal regions.
