Implementation of fall sensors in long-term care : An interview study to identify promoting and inhibiting factors from the perspective of professional caregivers

Digital support systems are becoming increasingly more important in long-term inpatient care facilities. Welfare technologies have the potential to make avaluable contribution to maintaining independence in advanced age. At the same time the technologies can support professional caregivers. The aim of the study was to describe the expectations and experiences with anew technology, using the example of afall sensor system, from the perspective of professional caregivers. We used aqualitative design with semistructured interviews in two long-term inpatient care facilities. In one facility, three individual interviews took place, while in the other long-term care facility, agroup interview with three nursing professionals was conducted. Additionally, one individual interview was conducted with aperson in aleadership role in each facility. The time from implementation of the fall sensors to the interviews was between 1 and 3 months. Data were analyzed using qualitative content analysis in MAXQDA. The study demonstrated that there was acorrespondence between expectations of and retrospective experiences with the new technology among professional nurses. The main facilitating factors of the implementation that were identified were timely information about the risk of falling or afall that has occurred, maintenance of residents' autonomy and freedom of movement as well as the enhancement of the sense of security among nursing professionals and the associated psychological relief effect. The inhibiting factors of the implementation were compulsory presetting, false alarms and faulty handling of the technology due to missing knowledge.

Laboratory Experimental Study on the Pressure Relief Effect of Boreholes in Sandstone under High-Stress Conditions

To study the effects of deep rock drilling pressure relief under high stress conditions in enhanced geothermal systems, two kinds of drilling pressure relief experiments were conducted on sandstone—the staged drilling of pressure relief holes before peak stress and one-time drilling. Pressure relief experiments were carried out on sandstone with two borehole methods of the stage-by-stage drilling and one-time drilling of pressure relief boreholes ahead of the experiments. FLAC3D was used to analyze the plastic zone evolution during drilling and the relationship between stress and plastic zone volume. The results reveal the pre-peak stress change characteristics and pressure relief features of non-prefabricated boreholes under high stress. The experiments show that the staged drilling of pressurized samples involves stages of rapid and gradual decreases in stress, with total relief amplitudes increasing but single-borehole relief decreasing with more holes. Under the same conditions, staged drilling has better relief effects and results in greater energy dissipation, indicating that incremental pre-peak pressure relief is beneficial for reducing the surrounding rock’s impact tendency and improving stability. The research results can provide good guidance and reference for the long-term stability analysis of borehole-containing rock and rock burst hazard control.

Do Tax Incentives Increase Firm Innovation? An RD Design for R&D, Patents, and Spillovers

We present causal evidence of R&D tax incentives’ positive impacts on a firm’s own innovation and that of its technological neighbors. Exploiting a change in size-based eligibility thresholds for R&D tax relief, we implement a Regression Discontinuity Design using administrative data. We find significant effects of tax relief on (quality-adjusted) patenting (and R&D) that persist up to seven years, and evidence of R&D spillovers on the innovation of technologically close firms. We can rule out elasticities of patenting with respect to R&D user cost of under 2 at the 5 percent level and show that our large effects are driven by financially constrained treated firms.

Tinnitus Relief Effect According to the Stimulus Listening Method of Sound Therapy

Purpose: This study investigated the tinnitus relief effect of the stimulation listening method in sound therapy. Methods: The participants were randomly divided into two groups: 16 in the continuous listening group and 15 in the intermittent listening group. The participants listened to broad-band noise at the mixing point level for 3 months, either continuously for 2 hours or intermittently 4 hours for 30 minutes, depending on the group allocation. The results of this study were confirmed by measuring scores through the Korean version of the Tinnitus Primary Function Questionnaire (K-TPFQ) and visual analog scale (VAS) for tinnitus loudness and annoyance at pretreatment and at 1, 2, and 3 months follow-ups. Results: Average scores of the K-TPFQ and VAS for tinnitus loudness and annoyance significantly improved with the duration of sound therapy in both the continuous listening and intermittent listening groups (<i>p</i> < 0.05). However, there was no difference between the two groups regarding the stimulation listening method in sound therapy, and no significant interaction effects were confirmed. Conclusion: The method of listening to the sound therapy continuously for 2 hours and the method of listening intermittently for 30 minutes had similar tinnitus relief effects.

Aged black tea alleviates constipation in mice by modulating intestinal neurotransmitters and decreasing AQP3 and AQP9 expression

Background: Black tea is fully fermented tea with abundant functional components that benefit the gastrointestinal tract. But whether black tea extract relieves constipation is unknown. Therefore, we used loperamide to induce constipation in mice to assess the therapeutical effect of extracts from aged black tea with different storage times.
 Design: Sixty-three C57BL/6J male mice were randomly divided into Control group (Con), Model group (Mod), Positive group (Pos), aged 6 years group (15Y), aged 4 years group (17Y), aged 2 years group (19Y), and unaged group (21Y). Mice were given loperamide (20 mg/kg, twice a day) to induce constipation for 10 days, and black tea extracts (500 mg/kg) were intragastrically given for 7 days while continuing modeling.
 Results: The results showed that black tea extracts relieved constipation symptoms by improving defecation weight, fecal water content, and gastrointestinal transit rate. Black tea extracts can also protect colon tissue, regulate serum neurotransmitters, increase the levels of excitatory neurotransmitters motilin (MTL) and substance P (SP), and decrease the levels of inhibitory neurotransmitters vasoactive intestinal peptide (VIP) and nitric oxide (NO). Immunohistochemistry (IHC) showed that black tea extracts were able to reduce AQP3 and AQP9 expression in the colon of constipated mice. In addition, Reverse transcription-quantitative polymerase chain reaction (RT-qPCR) showed that black tea extracts could decrease AQP3 and AQP9 mRNA expression. The relief effect of aged black tea (15Y) with the longest storage was better than that of other years, which may be due to the role of active ingredients such as thearubigins (TRs), soluble sugar, tea polysaccharide (TPS), gallic acid (GA), and catechin gallate (CG) in aged black tea.
 Conclusions: Based on these results, we believe that regular consumption of black tea is effective in relieving constipation, and that black tea is more effective in relieving constipation as the storage time increases.

Experimental study and evaluation on the weakening of bursting liability of coal with boreholes

Borehole pressure relief technology is the most commonly used method for stress control in the prevent of coal burst. Because coal burst is a dynamic failure phenomenon of coal driven by energy, compared with stress transfer, the effect of pressure relief should also be evaluated from the perspective of energy storage and dissipation. Uniaxial compressing tests of coal specimens with different boreholes are carried out. With increase of the borehole diameter and number, the peak elastic strain energy, energy release velocity, fragments kinetic energy and ejection velocity of coal all decrease. Compared with intact coal specimen, the kinetic energy of the coal specimen with one 14 mm borehole is droping to 39.91 %, the ejection velocity decreases from 9.74 m·s−1 to 6.07 m·s−1. The uniaxial compressive strength, bursting energy index, and modified bursting energy index of the coal specimen with boreholes show a negative exponential correlation with the diameter and number of boreholes, while the dynamic fracture duration shows a positive exponential correlation. In order to evaluate the effect of borehole pressure relief, energy pre-release index, energy dissipation-increasing index, and bursting liability weakening index are proposed. These three indexes are positively correlated with the diameter and number of boreholes, which can better reflect the effect of pressure in the perspective of energy storage and dissipation.

Study on the Energy Release Law of Overburden Rock Breaking and Anti-Rockburst Technology in the Knife Handle Working Face of a Gently Inclined Coal Seam

This study aims at the problems of the difficulty in controlling the stability of the surrounding rock and the high-impact danger of knife handle-type working face mining. We take the I010206 working face of Kuangou Coal Mine in Xinjiang as the engineering background, establish the mechanical model of roof periodic fracture and the FLAC3D numerical model of a working face, and analyze the evolution characteristics of the surrounding rock stress and energy when the working face is widened, revealing the mechanism of induced impact caused by overburden fracture in the working face, putting forward the technology of hydraulic fracturing to relieve the danger in the roof area, and comparing the pressure relief effect. The research results show the following: (1) After the working face is widened, the overlying strata load is transferred to the coal seam in front of the working face and the upper and lower sides of the working face. after mining; the abutment pressure of the I010408 working face in the B4-1 coal seam is superimposed with the abutment pressure of the I010206 working face in the B2 coal seam, the stress concentration is higher, and the lateral support pressure of the goaf forms a high static load. The large-area roof caving forms a high dynamic load. All of them are more likely to induce rockburst. (2) In knife handle-type working face mining, the peak value of the advanced abutment pressure in working faces first decreases and then increases, and the advanced abutment pressure increases from 10.31 MPa to 14.62 MPa; the peak value and concentration degree of strain energy density increase with the increase in working face width. (3) Measures were proposed to weaken the hydraulic fracturing roof in advance. After using hydraulic fracturing technology, the pressure step distance of the working surface roof was reduced, and the microseismic energy frequency was significantly reduced. These measures reduced the impact risk of the working face and ensured the safe mining of the working face.

Prevention of postoperative pain after total hip arthroplasty in patients with proximal femur fractures

Introduction Proximal femur fractures can be associated with nailing and total hip arthroplasty (THA). Treatment of elderly inpatients necessitates adequate postoperative pain relief. Obese patients require specific inpatient and outpatient treatments.The objective was to evaluate the effectiveness of pain relief in obese patients at the stages of rehabilitation after primary THA performed for a proximal femur fracture.Material and methods VAS score was compared in two groups of 60 clinical cases to evaluate the effectiveness of postoperative multimodal pain relief using the author's method.Results Comparable results of an effective and stable pain relief were obtained in the two groups by the time the patient was discharged from the hospital 5-6 days after THA. Multimodal analgesia with a glucocorticosteroid injected in the projection of the sacroiliac joint provided an effect being greater by 29 % than with use of opioids after two postoperative days and by 11 % after five postoperative days.Discussion Old age, comorbidities are associated with optimal surgical strategy. THA in patients with extra-articular proximal femur fractures can improve the rehabilitation potential early after surgery and general clinical and functional results providing high quality of life in the late rehabilitation period.Conclusion THA demonstrated a stable positive effect of pain relief in the study group of patients with proximal femur fractures, regardless of the weight and the height. Positive dynamics in pain relief was seen in patients with elevated BMI of any gradation, including those with BMI ≥ 40.

Numerical Simulation Analysis Method for Rockburst Control in Deeply Buried Caverns

Investigating the mechanism and measures of controlling rockburst in deeply buried underground caverns is a prerequisite for ensuring the safety of personnel, reducing the damage to construction equipment caused by the rockburst, and making the project economical and efficient. Efficient analysis methods for evaluating rockburst control in underground caverns are crucial for qualitatively selecting rockburst control methods and quantifying the effectiveness of rockburst measures. Based on the mechanism of energy accumulation in rock mass and the occurrence of rockburst as well as the active methods for controlling rockburst, we propose a mathematical model for simulating borehole stress relief using implicit borehole elements. In this modeling approach, we combine vector superposition in different borehole directions to analyze the effect of borehole stress relief on improving the external environment of the rock mass. Based on the interaction between the anchor support and the surrounding rock as well as the implementation of passive rockburst control measures, we propose a mathematical model that utilizes the implicit anchor column elements to simulate the reinforcement of the surrounding rock with anchors. By combining system anchors into arches and suspending anchors to reinforce the caverns, the overall stiffness of the surrounding rock can be improved and the stress accumulation can be alleviated. The coordinated deformation between the surrounding rock and the anchor provides support to prevent the rockburst. The effects of two rockburst control measures, borehole releasement and anchor reinforcement, are analyzed using both the strength theory and the energy theory. Engineering examples are provided to illustrate that the use of borehole elements to simulate local stress relief can effectively improve the external environment of the rock mass to control the occurrence of rockburst. Additionally, the mechanism of using anchor column elements in combination with the surrounding rock elements to enhance the overall stiffness of the rock mass and prevent rockburst is explored.

Role and anti-inflammatory mechanisms of acupuncture and moxibustion therapy on pain relief through NOX-ROS-NLRP3 pathway in CCI rats models.

To observe the effects of acupuncture and moxibustion therapy on pain relief in sciatica rats and to explore the mechanism of its anti-inflammatory effect. SPF grade 4-6-week-old Kunming rats were randomly divided into 5 groups including a blank group, sham-operated group, model group, acupuncture, and moxibustion (AnM) group, and positive group. A total of 10 rats were included in each group. The model group, the AnM group, and the positive group were prepared by ligating the left sciatic nerve. AnM group was used for acupuncture and moxibustion therapy intervention, and the positive group was rendered to quick-acting sciatica pills once a day for 7 days (3 courses of treatment). The blank group, sham-operated group, and model group were not treated. The changes in thermal and mechanical pain thresholds were observed before and after the operation, and the morphological changes of the dorsal horn of the spinal cord in the lumbosacral region of the rats in each group were observed by HE staining after the courses of treatment finished. The contents of IL-1β, IL-6, IL-18, and TNF-α were measured by ELISA and the expressions of NOX1, NOX2, NOX4, and NLRP3 genes were detected by RT-qPCR while the protein expressions of NOX1, NOX2, NOX4 and NLRP3 were analyzed by Western blotting. The AnM and positive group showed a significant increase in thermal and mechanical pain thresholds after treatment, while there was no significant change in the model group. As compared to the control group, the contents of IL- 1β, IL-6, IL-18, and TNF-α, as well as the relative expressions of NOX1, NOX2, NOX4, and NLRP3 genes were significantly increased in the model group (P < 0.05 or P < 0.01). As compared to the model group, the contents of IL-1β, IL-6, IL-18, and TNF-α, as well as the relative expressions of NOX1, NOX2, NOX4, and NLRP3 genes significantly decreased in the AnM and positive groups (P < 0.05 or P < 0.01). The pathological changes of inflammatory infiltration of tissue cells in the dorsal horn of the lumbosacral spinal cord were slowed in the AnM group. Acupuncture and moxibustion therapy have a positive effect on pain relief and anti-inflammatory effects in CCI sciatica rats, which may point to the regulation of NOX1, NOX2, NOX4, and NLRP3 expressions, and inhibition of ROS.

Zanthoxylum armatum DC fruit ethyl acetate extract site induced hepatotoxicity by activating endoplasmic reticulum stress and inhibiting autophagy in BRL-3A models

Ethnopharmacological relevanceZanthoxylum armatum DC (Z. armatum) is renowned not only as a culinary spice but also as a staple in traditional ethnic medicine, predominantly in Southeast Asia and various other regions. Recent research has unveiled its multifaceted pharmacological properties, including anti-inflammatory, antibacterial, and toothache relief effects. Nonetheless, some studies have reported the potential toxicity of Z. armatum, emphasizing the need to further explore its toxicity mechanisms for safer application. Aim of the studyThis study investigated the effect and mechanism of hepatotoxicity in BRL-3A cells induced by Z. armatum. Materials and methodsThe compounds of the ethyl acetate extract of Z. armatum (ZADC-EA) were identified by ultrahigh performance liquid chromatography coupled with quadrupole-orbitrap high resolution mass spectrometry (UPLC-Q-Orbitrap HRMS). The hepatotoxicity of the extract was evaluated by detecting cell viability, aspartate aminotransferase (AST), alanine aminotransferase (ALT), and lactate dehydrogenase (LDH) activity, and apoptosis. Endoplasmic reticulum stress, autophagy, and apoptosis were detected by Ad-mCherry-GFP-LC3B, flow cytometry, and Western blot to explore the mechanism of hepatotoxicity induced by ZADC-EA. ResultsUPLC-Q-Orbitrap HRMS analysis revealed the presence of compounds belonging to flavonoids, terpenoids, and alkaloids. The IC50 value of ZADC-EA was 62.43 μg/mL, the cell viability of BRL-3A decreased in a time-dose dependent manner, and the levels of AST, ALT, and LDH were upregulated. In addition, ZADC-EA-induced increased expression of eIF2α-ATF4-CHOP pathway proteins, inhibited autophagy, and promoted apoptosis. ConclusionsThis study provides insights into the hepatotoxicity mechanisms of ZADC-EA on BRL-3A cells. It was found that ZADC-EA could induce endoplasmic reticulum stress and inhibit autophagy, then intensify apoptosis, and endoplasmic reticulum stress could exacerbate autophagy inhibition.

Bi-directional associations between mask usage and beliefs about reasons for masking before and after the downgrading of the legal status of COVID-19 in Japan: A longitudinal study

It is important to clarify the bi-directional associations between mask usage and mask-usage motivations. Therefore, this study clarified the changes in mask usage and beliefs about reasons for masking before and after the downgrading of the legal status of COVID-19 in Japan and analyzed the bi-directional associations between the two. Online surveys were conducted in two sets among people aged 20–69 years living in Japan: the first before the downgrading of the legal status of COVID-19, between April 18–19, 2023; and the second afterward, June 6–15, 2023. After a total of 291 participants completed both surveys, associations between using masks and beliefs about reasons for doing so were analyzed using a cross-lagged panel model. Mask usage decreased slightly but significantly between the first and second sets. Of the eight beliefs regarding mask usage, slight but significant decreases were observed in terms of relief and information effects. There was also a significant association between socio-psychological reasons other than infection risk avoidance (such as norm and relief) during the first set and mask usage during the second set. Contrarily, mask usage during the first set was significantly associated with the reasons for infection risk avoidance during the second set. The impact of downgrading COVID-19's legal status in Japan on mask usage and reasons for masking was found to be limited. In terms of promoting or mitigating mask usage, the significance of risk communication based on socio-psychological reasons other than infection risk avoidance such as norms and relief was highlighted.

Mechanical response and microstructure evolution of SiC particle-reinforced Al-MMCs under ultrasonic loading

High volume fraction(≥45 vol.%) SiC particle-reinforced Al matrix composites are difficult for forming and manufacture. A simple and efficient method is proposed in this research to realize rapid plastic deformation at room temperature. By applying ultrasonic load to the composites, 40% compressive strain is obtained within 1s, while the stress is only 59MPa, about 1/10 of its compressive strength. Ultrasonic loading can produce a high instantaneous strain rate (up to 103 s-1) and a high-frequency (20000Hz) cyclic load compared with conventional loading. The stress superposition and relief effects produced by ultrasonic loading lead to the diffusion and annihilation of dislocation in the Al matrix, the dispersion, and the plastic deformation of SiC particles. The microstructure evolution reduces the accumulation of dislocation, promotes the formation of sub-grain, weakens the deformation texture, and improves the synergetic deformation of Al and SiC.

Effect of cross-cultural education combined with music therapy on anxiety disorders

BackgroundAnxiety disorder usually refers to anxiety disorder. Common anxiety disorders include social phobia and separation anxiety disorder. Different anxiety disorders have different incidence rates. At present, the pathogenesis of anxiety disorder is not yet clear, but its common causes include genetic and psychological factors. Music therapy treats diseases from both physiological and psychological perspectives.Subjects and MethodsIn order to analyze the relief effect of cross-cultural education combined with music therapy on academic anxiety disorder in university students, the study selected 80 students with anxiety disorder. They were randomly divided into two groups, the observation group and the control group, with 40 students in each group. Among them, the control group only received cross-cultural education, while the observation group received music therapy based on cross-cultural education. Both groups were treated three times a week for a total of 8 weeks. After the treatment, the study evaluated the treatment results using the Self Rating Anxiety Scale, Self Rating Depression Scale, and SPSS23.0.ResultsThe results showed that there was a significant decrease in anxiety and depression scores between the observation group and the control group students after treatment, and there was a significant difference compared to before treatment (P&lt;0.05). In addition, after treatment, the anxiety and depression scores of the observation group students decreased more than those of the control group, and the difference between the two was significant (P&lt;0.05).ConclusionsIn summary, the combination of cross-cultural education and music therapy in universities has a certain alleviating effect on students’ academic anxiety disorder.

Online teaching mode for English translation majors on alleviating students’ learning phobia

Background Learning phobia is a form of anxiety caused by learning pressure, characterized by fear of learning, difficulty in thinking about anything, and severe physical reactions such as dizziness and palpitations. At present, the employment situation in the English translation major is relatively severe, and academic pressure has become increasingly high, leading to some college students showing varying degrees of resistance or even fear when facing their studies, which has a negative impact on their own development.Subjects and Methods The study conducted the Cochrane Library search on past studies related to learning phobia, using keywords such as phobia, neurobiology, and psychotherapy. Fifteen English translation major students with learning phobia were selected for a three-month online teaching program. Before and after the online teaching, a questionnaire survey was conducted on their willingness to learn, and SPSS 23.0 was used for statistical analysis.ResultsThe results show that online teaching for college students from English translation majors has a certain effect on alleviating learning phobia. It can be found that students’ learning willingness before and after online teaching has significantly improved (P&lt;0.05), through statistical analysis and t-tests of effective survey questionnaires collected before and after online teaching.ConclusionsLearning phobia among college students is an important factor that affects their mental health and learning efficiency. Effective measures and timely intervention and treatment are urgently needed. The analysis and research on the relief effect of online teaching mode for English translation majors on learning phobia among college students is of great significance for improving their learning outcomes.

Repetitive transcranial magnetic stimulation in central post-stroke pain: current status and future perspective.

Central post-stroke pain (CPSP) is an incapacitating disorder that impacts a substantial proportion of stroke survivors and can diminish their quality of life. Conventional therapies for CPSP, including tricyclic antidepressants, anticonvulsants, and opioids, are frequently ineffective, necessitating the investigation of alternative therapeutic strategies. Repetitive transcranial magnetic stimulation (rTMS) is now recognized as a promising noninvasive pain management method for CPSP. rTMS modulates neural activity through the administration of magnetic pulses to specific cortical regions. Trials analyzing the effects of rTMS on CPSP have generated various outcomes, but the evidence suggests possible analgesic benefits. In CPSP and other neuropathic pain conditions, high-frequency rTMS targeting the primary motor cortex (M1) with figure-eight coils has demonstrated significant pain alleviation. Due to its associaton with analgesic benefits, M1 is the most frequently targeted area. The duration and frequency of rTMS sessions, as well as the stimulation intensity, have been studied in an effort to optimize treatment outcomes. The short-term pain relief effects of rTMS have been observed, but the long-term effects (> 3 months) require further investigation. Aspects such as stimulation frequency, location, and treatment period can influence the efficacy of rTMS and ought to be considered while planning the procedure. Standardized guidelines for using rTMS in CPSP would optimize therapy protocols and improve patient outcomes. This review article provides an up-to-date overview of the incidence, clinical characteristics, outcome of rTMS in CPSP patients, and future perspective in the field.

The relief effect of teacher oral corrective feedback on English learning anxiety symptoms of vocational college students

BackgroundFor second language learning, students generally experience symptoms of learning anxiety. As a complex emotional variable, learning anxiety not only has an impact on students’ psychological feelings but also leads to students’ aversion to English learning in severe cases, thereby affecting learning efficiency.Subjects and MethodsIn order to explore whether teachers’ oral corrective feedback has the effect of alleviating students’ learning anxiety, the study focuses on two classes in vocational schools. Two classes each have 45 students, divided into an experimental class and a control class. The experimental class increases the teacher’s oral corrective feedback during normal teaching, while the control class follows the original teaching mode for normal teaching. The Foreign Language Listening Anxiety Scale was used to test students from both classes before and after the teaching experiment.ResultsBefore the teaching experiment, the English learning anxiety of the students in the experimental class and the control class was at a moderate level, with values of 3.5294 and 3.5061, respectively. After the teaching experiment, there was a significant difference in the English learning anxiety results between the experimental class and the control class, with values of 2.7451 and 3.5347, respectively.ConclusionsOverall, strengthening the interaction between teachers and students in English teaching and providing appropriate oral corrective feedback have an alleviating effect on the anxiety symptoms of vocational college students in English learning.

Landscape design and the therapeutic effect of haloperidol on BD

BackgroundLandscape design and art psychotherapy are two widely used methods in the field of mental health. Haloperidol is a common drug for treating bipolar disorder. Based on the theory of art psychotherapy, the relief effect of landscape design combined with haloperidol on patients with bipolar disorder will be studied.Subjects and MethodsSelect 80 patients with bipolar disorder and randomly divide them into two groups: the experimental group and the control group. The control group patients were treated with haloperidol, while the experimental group was treated with garden design combined with haloperidol.
