Sex-specific differences in trimethylamine N-oxide (TMAO) concentrations before and after cardiac rehabilitation in acute myocardial infarction patients

Trimethylamine N-oxide (TMAO) is a biomarker of cardiovascular risk and may enhance the progression of atherosclerosis. The aim of the study was to determine whether there are sex-specific differences in TMAO concentrations before and after cardiac rehabilitation in acute myocardial infarction (AMI) patients. A total of 56 participants [45/56 (80.4 %) males, 11/56 (19.6 %) females] were drawn from AMI inpatients hospitalized at the Division of Cardiology, Medical University of Graz, Austria. For the assessment of TMAO, serum samples were collected within the first day after hospital admission due to AMI and at the start and end of cardiac rehabilitation. Shortly after hospital admission due to AMI, females had significantly higher TMAO blood concentrations than males. These initially high TMAO levels remained almost unchanged in the female AMI patients until the start of cardiac rehabilitation and only reached the lower TMAO concentrations observed in the male patients after rehabilitation [female patients: TMAO (acute myocardial infarction) = 5.93 μmol/L (SE = 1.835); TMAO (start of rehabilitation) = 5.68 μmol/L (SE = 1.217); TMAO (end of rehabilitation) = 3.89 μmol/L (SE = 0.554); male patients: TMAO (acute myocardial infarction) = 3.02 μmol/L (SE = 0.255), TMAO (start of rehabilitation) = 3.91 μmol/L (SE = 0.346), TMAO (end of rehabilitation) = 4.04 μmol/L (SE = 0.363)]. After AMI, women might be at higher cardiovascular risk due to persistently higher levels of TMAO. High TMAO levels in women might decrease after cardiac rehabilitation due to cardiac rehabilitation-associated lifestyle modifications. These lifestyle modifications after AMI might also prevent increases in TMAO concentrations in men.
Application of Explicit Analysis Method on Marine Vibration Characteristic Study

Based on theoretical analysis,explicit analysis method is introduced as an amends to harmonic analysis for large scale calculation problems which cannot be solved with implicit analysis method due to the shortage of memory.The study shows that explicit analysis method can smooth the defects of calculation scale caused by implicit analysis.And explicit analysis method can show more details intuitively of real structures.Considering influence of pulsating force of propellers and bearings,the study on the influence of vibration characteristic of a ship is performed.Research shows that with the same moving speed,vibration of the ship is greater when double propellers are working rather than four propellers.The operation of four propellers working together is recommended to minimize vibration of the ship.
Association of participation in the Northern Finland Birth Cohort 1986 with mental disorders and suicidal behaviour

OBJECTIVES In prospective follow-up studies, participants are normally contacted during the follow-up period. Even though the idea is not to intervene, the studies conducted during follow-up may affect the target population. Our hypotheses were that participation in the prospective Northern Finland Birth Cohort 1986 study (NFBC 1986) increased the use of mental health services and reduced suicidal behaviour due to participation in follow-up studies. METHODS The NFBC 1986 study covered people with an expected date of birth between July 1985 and June 1986 in northern Finland (n=9,396). The participants of the NFBC 1986 were followed since the antenatal period with follow-ups including clinical examinations. The comparison cohort comprised people born in the same area in 1987 (n=8,959), who were not contacted. Registry data on psychiatric treatment, suicide attempts, and suicides were available. Crude risk ratios (RRs) and adjusted (for marital status and education) Mantel-Haenszel RRs were reported. RESULTS No increase in mental disorders were found in NFBC 1986 compared to comparison cohort. In the crude RR analysis of female participants, a lower risk for suicide attempts was found (RR, 0.67; 95% confidence interval, 0.49 to 0.92; p=0.011). CONCLUSIONS The results did not support our first hypothesis regarding the increased use of mental health services in the NFBC 1986 cohort. However, our second hypothesis gained some support as female participants of the NFBC 1986 had a lower risk of suicide attempts, although it was not due to a higher number of participants receiving psychiatric treatment.
A Lossless and Passive Voltage Spikes Clamping Circuit for SiC HERIC Inverter

When HERIC(High Efficient and Reliable Inverter Concept) inverter operates at the non-unit power factor, there are larger turn-off voltage spikes on freewheeling switches than operating at the unit power factor, which increases switching loss, devices voltage stress, and electromagnetic interference. Moreover, the turn-off voltage spikes are much larger in some high-frequency applications, owing to the larger di/dt. This paper analyzes the turn-off voltage spikes of freewheeling switches when the HERIC inverter operates at the non-unit power factor. On this basis, a passive clamping circuit is proposed, which is simple, cheap, and lossless, and its principle is analyzed. Finally, a 10kW prototype was used to verify the proposed circuit.
Environmental sustainability: farmers' views of housing systems for cattle

Abstract In the establishment and maintenance of a housing system for cattle by farmers, their perception of housing systems plays an important role in their decision to choose the environmentally sustainable housing system. The aim of this study was to determine farmers’ attitudes towards their role, environmental sustainability, and perceived government support, to determine whether the role of cattle farmers influences their perceptions of different cattle housing systems, and to create a typology of cattle farmers based on these attitudes. The paper was based on online surveys (n = 306) and five focus groups with Slovenian cattle farmers (n = 42). Results show that the majority of participants placed a higher value on production than on the environment, but had adopted animal and environmentally friendly housing systems to achieve higher production and profits and to receive full direct payments. Four groups of cattle farmers based on the attitudes towards their role, environmental sustainability, and perceived governmental support were identified: Productivists, Traditionalists, Abandoners, and Environmentalists. Most respondents belonged to the Productivist group, who believed that environmental measures have a negative impact on agricultural development. A characteristic of the smaller Traditionalist group is that these farmers claimed to have an obligation to preserve or improve the environment for future generations. For Environmentalists, environmentally friendly agriculture is most important. The smallest group identified consists of farmers who indicated their role as a farmer was not important because they were likely to give up farming. Systematically planned communication aimed at different groups of farmers is needed to promote acceptance of changes in housing systems for cattle that reduce the greenhouse effect. HIGHLIGHTS The majority of farmers placed a higher value on production than on the environment. They had adopted animal and environmentally friendly housing systems to achieve higher production and profits and to receive full direct payments. There were four groups of cattle farmers: Productivists, Traditionalists, Abandoners, and Environmentalists.
The Prediction Number of Smear Acid Resistant Bacteria on Positive Pulmonary Tuberculosis Infection Disease at Madiun City in 2021 to 2025

Tuberculosis (TB) is an infectious disease caused by Mycobacterium Tuberculosis Bacillus. The disease spreads in the air when people contract TB bacteria, such as coughing or sneezing. The lack of ability to anticipate the incidence of Acid Resistant Bacteria Positive Pulmonary TB in Madiun City is affected by the time and number of events that have not been appropriately foreseen. There is no map of regional vulnerability based on the time of occurrence. Hence, the incidence of Acid Resistant Bacteria Positive Pulmonary TB in Madiun city increases, determined by the total number of cases in 6 health centers, seven hospitals, and one prison. In 2015, there were 174 cases, then in 2019, 706 cases. The objective of this study is to predict the number of Acid Resistant Bacteria Positive Pulmonary TB suffering in 2021-2025 based on gender, health centers, and prisons in Madiun City and the overall incidence of cases in 2015-2019 is then foreseen in 2021 to 2025. This type of research is descriptive study research by employing Eviews with the ARIMA method. The population and samples in the study were all data of Acid Resistant Bacteria Positive Pulmonary TB case encompassing the sex of patients during 2015-2019 in Madiun City. The study aimed to predict the incidence of Acid Resistant Bacteria Positive Pulmonary TB in 2021-2025. The results of this study revealed the projection of Acid Resistant Bacteria Positive Pulmonary TB cases based on gender, health centers, hospitals, and prisons in Madiun City from 2020-2025, which experienced an increasing trend with the number of 933, 992, 1063, 1120, 1190 incidences respectively. This study is recommended for relevant agencies or health services to perform preventive efforts by involving trained policymakers and Health Cadis, particularly in preventing TB disease and reducing the high rate of predicting positive pulmonary TB smear incidences in the future.
Research on Startup Model of Aircraft Engine Based on Stage-Stacking Method

The main difficult in startup procedure modeling is the lack of component characteristics at low speed. A method combining a stage-stacking method and testing data is developed to calculate the low-speed characteristics. The efficiency variation of combustion and heat conservation between gas and metal are considered for startup procedure. Modeling method which is adopted for normal speed above ideling is successfully applied to startup model. The comparison between simulation and testing data for a turbo-shaft engine indicates that this state-stacking method has reasonable precision in the evaluation of component characteristics, and the startup model developed can be used to study the fuel flow schedule and estimate the starting characteristics.
Microencapsulated basil oil (Ocimum basilicum Linn.) enhances growth performance, intestinal morphology, and antioxidant capacity of broiler chickens in the tropics

Objective Microencapsulation is a technique to improve stability, bioavailability, and controlled release of active ingredients at a target site. This experiment aimed to investigate the effects of microencapsulated basil oil (MBO) on growth performance, apparent ileal digestibility (AID), jejunal histomorphology, bacterial population as well as antioxidant capacity of broiler chickens in a tropical climate. Methods A total of 288 one-day-old female broilers (Ross 308) were randomly allocated into 4 groups (6 replicates of 12 birds), based on a completely randomized design. Dietary treatments were as follows: i) basal diet (NC), ii) basal diet with avilamycin at 10 ppm (PC), iii) basal diet with free basil oil (FBO) at 500 ppm, and iv) basal diet with MBO at 500 ppm, respectively. Results Dietary supplementation of MBO improved average daily gain, and feed conversion ratio of broilers throughout the 42-d trial period (p<0.05), whereas MBO did not affect average daily feed intake compared with NC group. The broilers fed MBO diet exhibited a greater AID of crude protein and gross energy compared with those in other groups (p<0.05). Lactobacillus spp. and Escherichia coli populations were not affected by feeding dietary treatments. Both FBO and MBO had positive effects on jejunal villus height (VH), villus height to crypt depth ratio (VH:CD) and villus surface area of broilers compared to NC and PC groups (p<0.05). Superoxide dismutase level in the duodenal mucosa of MBO group was significantly increased (p<0.01), whereas malondialdehyde level was significantly decreased (p<0.01). Conclusion Microencapsulation could be considered as a promising driver of the basil oil efficiency, consequently MBO at 500 ppm could be potentially used as a feed additive for improvement of intestinal integrity and nutrient utilization, leading to better performance of broiler chickens.
Machine learning-based steering control for automated vehicles utilizing V2X communication

A neural network-based controller is trained on data collected from connected human-driven vehicles in order to steer a connected automated vehicle on multi-lane roads. The obtained controller is evaluated using model-based simulations and its performance is compared to that of a traditional nonlinear feedback controller. The comparison of the control laws obtained by the two different approaches provides information about the naturalistic nonlinearities in human steering, and this can benefit the controller development of automated vehicles. The effects of time delay emerging from vehicle-to-everything (V2X) communication, computation, and actuation are also highlighted.
Gamma Knife Radiosurgery With Mask Fixation Under General Anesthesia for Pediatric Patients

Gamma knife radiosurgery (GKS) is performed on children by frame fixation of the skull under general anesthesia. With the introduction of the Gamma Knife Icon, treatment by fixing with a thermoplastic mask has become possible. In this study, we performed GKS by mask fixation under general anesthesia, measured the accuracy, and examined whether an accuracy equivalent to that of frame fixation could be guaranteed. We included three children who underwent mask fixation under general anesthesia between September and November 2020. After the induction of general anesthesia, a patient marker was attached to the nose, and the movement of the marker before mask fixation was measured using a real-time high-definition motion management (HDMM) system. The movement of the patient marker from the start to the end of treatment after mask fixation was monitored and measured. After the induction of general anesthesia, the movement of the patient marker was ≤0.3 mm in two cases and ≥1.0 mm in one case without mask fixation. When the mask was fixed, it was ≤0.2 mm in all three cases. It was confirmed that the marker could move even under general anesthesia without mask fixation, and it could be suppressed to a minimum after mask fixation. With the mask fixation method devised in this study, GKS under general anesthesia for children seems to be a safe and highly accurate method.

DUAL CIRCULARLY POLARIZED WIDEBAND MAGNETO-ELECTRIC DIPOLE ANTENNA FOR WIRELESS APPLICATIONS

A wideband magneto-electric (ME) dipole with characteristics of dual-circular polarization is presented in this paper. The proposed antenna is composed of four horizontal radiation patches, four pairs of vertical radiation patches, a ground plane, a pair of wideband feeding networks, and novel crossed feeding structures which work as wideband 3-stage impedance matching transitions. The feeding networks which contain a Wilkinson power divider and a coupled-line phase shifter are printed on the bottom of the ground plane, and they can provide stable two-way output wideband signals with quadrature-phase. The proposed antenna works as a ME dipole with a wide operation bandwidth of 53.2% (S11 < −10 dB, and Axial Ratio (AR) < 3 dB) from 1.71GHz to 2.95GHz for right-hand circular polarization (RHCP) and 62% from 1.7GHz to 3.25GHz for left-hand circular polarization (LHCP), respectively.
DIGITALIZATION OF ADMINISTRATIVE PROCESS IN THE GERMAN HEALTHCARE SYSTEM WITH THE FOCUS ON DENTAL PRACTICES

The digitization of processes in healthcare offers the opportunity to reduce costs and at the same time increase the quality of treatment. A large number of studies show how digitization can optimize and automate processes in healthcare. However, no study has yet addressed the specific requirements of processes digitalization in dental practices. This paper examines the status quo and opportunities of process digitization for dental practices in the German healthcare system. A structured literature review was used to identify 25 previous relevant papers. Their categorization and analysis revealed existing research gaps, which were explored in detail based on semi-structured in-depth interviews with four dentists. The analysis shows that most organizations are at an early stage of digital transformation, but are actively working to improve the digitization of their processes. Our findings provide a detailed description of the current challenges and starting points for process digitization and optimization in dentistry. They serve as a basis for further development and help to improve the quality and efficiency of processes in healthcare.

Organizational aspects of neurorehabilitation at the outpatient stage

The study was aimed to evaluate the effectiveness of IRP implementation in patients of a specialized clinic providing long-term care to neurological and neurosurgical patients. Material and methods. The study was conducted in 2020-2021. on the basis of the MC "Expert Health" (Odessa, Ukraine). 83 patients undergoing neurorehabilitation program were examined. The correspondence of the fulfillment of key rehabilitation tasks in terms of time and quality was assessed. Additionally, the level of motivation and compliance of the patient was assessed using the MOT-Q questionnaires (for patients with previous TBI (n = 13), SRMS (for patients with stroke (n = 54) and with SRQ-E (for patients with other types of neurological pathology (n = 16). The overall level of compliance was assessed using the General Rehabilitation Adherence Scale (GRAS). The level of safety was assessed according to the following criteria: the presence of FAST certificates for personnel, a system for monitoring vital functions, equipment and consumables for the provision of emergency care. Statistical processing was carried out by methods of variance and correlation analysis, using the MedCalc 1.3 software. Results. There were not recorded any significant violations of safety principles in the provision of rehabilitation assistance in the certification of personnel according to FAST. The frequency of detecting cases of improper implementation of IRP did not exceed 6.0% (5 cases out of 83 analyzed). When assessing the relationship between the effectiveness of IRP and the level of compliance, a strong positive correlation was found - r = 0.78 Conclusion. 1. Provision of rehab services for neurological patients in the long term requires coordination of the actions of specialists at the intra-, inter-, and transdisciplinary levels. 2. A necessary condition for the functioning of a multidisciplinary team in the provision of rehabilitation care is certification of staff in the BLS systems - for allied health specialists and ACLS for physicians. 3. The effectiveness of IRP depends on the patient's compliance level (r = 0.78). 4. For the continuity of the rehabilitation process, it is necessary to involve relatives and facilitate their training in the basics of "home" rehabilitation.
Cluster based routing method using mobile sinks in wireless sensor network

ABSTRACT In recent years, due to technology development, applying WSNs has increased, and consequently, researchers have developed an interest in dealing with the problems of WSNs. The power-limitation issue of sensor nodes brings a serious challenge for employing WSNs. Clustering has a significant effect on increasing the network lifetime. Also, using mobile sinks is an ideal solution to improve network efficiency and lifetime as well as reducing end-to-end delay. In this study, all nodes are clustered and scored. Next, the nodes with the highest scores are selected as CHs. Then the network is partitioned. Here, mobile sinks have been applied to save the energy of nodes. The movement of the sinks, which are individually appointed to each section, is controlled by two parameters. The proposed method was simulated via MATLAB and was compared with PRD, ETX, EFW and PDX methods. The results revealed an improvement in energy consumption, end-to-end delay, packet delivery rate and the number of alive nodes in the network.
Virtual constraints based dynamical servo control for a class of underactuated mechanical systems

To overcome the shortcomings of underactuated mechanical systems which are unable to track arbitary point and trajectory,give full play to the resource and energy comsuming advantage and enlarge the application area,the dynamical servo control problem for a class of underactuated mechanical systems was studied.The dynamcal servo control aims to realize reaching any point in configuration space by planning and tracking specific trajectory.The virtual constraints method was used to plan the dynamcial servo trajectory.By constructing the constraint relation between freedoms and analysing the system zero dynamics,periodic orbits meeting system dynamics were gained easily.Using the inner connection between the virtual constraints and orbit function,a orbit tracking controller was designed based on Lyapunov stability theory.The experiment was performed on the Acrobot Platform and experiment results shows the effectiveness of the trajectory planning method and control method.
