Effectiveness of Neural Mobilization Technique in Subjects with Lumbar Radiculopathy: A Randomized Controlled Trial

BACKGROUND AND OBJECTIVE: Radicular low back pain is a disorder involving the dysfunction of the lumbosacral nerve roots. Clinical rehabilitation approaches for Radicular LBA include kinesiotherapy, and physical therapy procedures: rest, heat, ultrasound, TENS, but evidences regarding their effectiveness are lacking. Previous studies found that neural mobilization is more effective in reducing pain. The aim of the study is to determine the effectiveness of Neural Mobilization on pain in subjects with lumbar radiculopathy. METHODS: 30 subjects were selected by simple random sampling and assigned into Experimental group (n=15) & Control group (n=15). The subjects in Experimental group were given Neural Mobilization in addition to traditional therapy and control group were given traditional therapy alone. All the participants were assessed with NPRS. RESULTS: After the analysis, the results were found to be effective in improvement of pain in both groups NPRS score (p<0.0001). But there is a high significance in Experimental group when compared to control group. CONCLUSION: This study concluded that Neural Mobilization along with traditional therapy is more effective in reducing pain in subjects with lumbar radiculopathy. Keywords: Neural Mobilization, Low back ache, Numerical pain rating scale.

A phase III, open-label, multicenter, randomized controlled trial of tunlametinib versus investigator-selected chemotherapy in patients with advanced NRAS-mutant melanoma who had previously received immunotherapy.

TPS9606 Background: NRAS-mutant melanoma is an aggressive subtype with worse prognosis. However, no targeted therapy has been approved to date worldwide. Tunlametinib (HL-085) has showed an encouraging efficacy (confirmed ORR:34.8%, mPFS:4.2 months) with a manageable safety profile in phase II pivotal registrational study, which was published in ASCO 2023 annal meeting (NO.:9510). Here, we present the design of phase III randomized controlled study. Methods: This is a multicenter, two-arm, open-label, randomized controlled phase III confirmatory clinical trial to evaluate the efficacy and safety of tunlametinib in comparison with the combination chemotherapy of investigator's choice in advanced NRAS-mutant melanoma patients who had previously received immunotherapy. A total of 165 subjects from about 12 sites in China will be included and randomly assigned to the corresponding treatment group in 2:1 ratio. Two stratification factors before randomization: LDH level and whether have received chemotherapy. The key inclusion criteria included: a) Patients with unresectable stage III or metastatic IV melanoma confirmed by histology or cytology; b) History of immunotherapy failure or could not tolerate immunotherapy; c) Be able to provide NRAS mutation positive test report at baseline and provide sufficient histological specimens for NRAS mutation confirmation by central laboratory. Experimental group subjects will receive continuous administration of tunlametinib 12mg BID, 28 days per cycle. Control group subjects will receive one of the following regimens which according to investigator's choice (paclitaxel plus carboplatin, or temozolomide plus cisplatin, or dacarbazine plus cisplatin) , 28 days per cycle. The two groups will receive continuous therapy until disease progression or intolerable toxicity. The primary endpoint is progression-free survival which assessed by independent radiology review committee. Secondary endpoints included overall survival, objective response rate, disease control rate, duration of response, safety, pharmacokinetics and exposure-response. Exploratory endpoints are to evaluate quality of life between two groups and to development a companion diagnostic kit for NRAS gene mutations detection. This study is currently open for enrollment.

Attitudes of college seniors toward graduate student loan debt: the role of financial education

PurposeThis paper aims to examine prospective graduate students' attitudes toward educational loan borrowing in an experimental setting.Design/methodology/approachParticipants were randomly assigned to two treatment groups and one control group. Subjects in experimental group 1 received financial education: a short online course on the economic viability of getting a master's degree and how to finance it with a graduate student loan, while subjects in experimental group 2 received financial education along with information on the availability bias.FindingsRelying on a control group in the assessment of financial literacy education intervention impacts, this research finds positive causal treatment effects on individuals’ attitudes toward debt-financed graduate education. In comparison to the control group, experimental subjects perceived the possibility of going into debt with a graduate loan to complete a master’s degree as less stressful and worrying.Practical implicationsThis study has important educational policy implications to prevent students from stopping investing in human capital by perceiving educational loan debt as something stressful or worrying. The results can help potential (and current) grad students develop a feasible financial plan for graduate school by encouraging higher education institutions to implement educational loan information and financial education into university seminar courses for better graduate student loan decision-making.Originality/valueStudent attitudes toward debt have been analyzed in the context of higher education, but only a few researchers internationally have used an experimental design to study personal financial decision-making.

Effects of Specific Training Using a Rowing Ergometer on Sport Performance in Adolescents

The main purpose of this study was to study the effects of a specific rowing ergometer training program on the athletic performance of young adolescents (N = 56; 11.73 ± 1.4 years old) compared to a workout based on general strength training. An eight-week training program was implemented, with four sessions per week and two hours per session. The sample was divided into two groups: a control group (CG) that performed circuit training with exercises aimed at building general strength and an experimental group (EG) who focused on specifically training on a rowing ergometer (rowing machine). The data obtained in a rowing meter test over the competition distance were analyzed to obtain the average power attained (W) at the beginning of the training, at the middle (4 weeks), at the end of the training (8 weeks) and one year after the experimentation. The results show that although both forms of training improve the average W obtained in both categories, the EG subjects (+29.94 W) obtained better averages in all phases of the study compared to the CG (+5.88 W). Furthermore, this increase was greater in male rowers (+34.06 W) than in female rowers (+24.54 W). These results reveal that a specific rower rowing ergometer training program has a more significant effect than a general strength program and these effects can even be observed a year after the intervention.

Evaluation of a Course to Teach Medical Students Latent Hazard Identification in the Operating Room.

To improve situational awareness in the operating room (OR), avirtual online operating room of hazards (ROH) with deliberately placed risks was created. We hypothesized that subjects first participating in the virtual online ROH would identify more hazards during an in-person ROH exercise in a physical OR than those in the control group who only received didactic training. We conducted a randomized controlled trial at a major academic medical center, enrolling 48 pre-clinical medical students with no previous OR exposure during their classes. Control and experimental group subjects participated in a brief, online didactic orientation session conducted live over Zoom (Zoom Video Communications, Inc., San Jose, CA) to learn about latent hazards in the OR. Experimental group subjects further interacted with a virtual onlineoperating ROH in which latent hazards were present. The fraction of deliberately created latent hazards placed in a physical, in-person OR identified by subjects was calculated. Experimental group subjects identified a significantly larger fraction of the created hazards (41.3%) than the control group (difference = 16.4%, 95% CI: 11.3% to 21.4%, P < 0.0001). There was no difference in the number of non-hazards misidentified as hazards between the groups. Participation in the virtual online environment resulted in greater recognition of latent operating room hazards during a simulation conducted in a physical, in-person OR than in a didactic experience alone. Because creating an in-room experience to teach the identification of latent hazards in an OR is resource-intensive and requires removing the OR from clinical use, we recommend the virtual online approach described for training purposes. Adding items most misidentified as hazards is suggested for future implementation.

#19 : Green Tea Extract Inhibits Endometriosis Progression by Increasing Superoxide Dismutase Serum Levels in the Rat Models

Background and Aims: Endometriosis is a gynecological disorder defined as the presence of endometrial tissue outside the uterine cavity and affecting 10-15% of females of reproductive age. Oxidative stress has been reported as one of the main promoting factors of this disease. Green tea and its anti-angiogenic and antioxidant properties have promising potential to prevent the progression of endometriosis. This study aims to investigate the effect of green tea extract on endometriotic implant area and serum superoxide dismutase (SOD) levels in endometriosis rat models. Method: Twenty-six Balb/c female rats were randomized into two groups of equal size: experimental group (EG) and control group (CG). All subjects in EG were given green tea extract 3 mg daily for 14 days. Endometriosis was induced on the fourteenth day in all subjects in both groups. The data of the endometriotic implant area and serum SOD were obtained and analyzed fourteen days after the induction of endometriosis. Results: The endometriotic implant area of the group treated with green tea extract was significantly lower (p=0,022) RR=0,455, 95%CI=0.065-0,96) compared to the control group. The serum level of SOD in EG and CG were 5.33±0.52 ng/ml and 5.20±0.91 ng/ml, respectively (p=0.507). Conclusion: Green tea extract inhibits endometriotic implant progression and increases the level of serum SOD in endometriosis-induced rat models.

Effects of pumpkin on benign prostatic hyperplasia: a systematic review and meta- analysis

Introduction: Benign prostatic hyperplasia (BPH) is a common condition affecting aging men worldwide. Pumpkin and its extracts are enriched with antioxidant, anti-androgenic and anti-inflammatory properties.Objectives: To systematically review the effect of pumpkin on the reduction of lower urinary tract symptoms (LUTS) due to bladder outflow obstruction in BPHMethods: The review (PROSPERO ID: CRD42020181395) perused PubMed, EMBASE, Cochrane Library, CINAHL and AGRICOLA databases in two rounds independently by two reviewers according to three screening questions: being a pumpkin related human study, having BPH related outcomes and including quantifiable measurements. Risk of bias assessments were done with GRADE and ROBINS-I Criteria. After assessing the clinical, methodological and statistical heterogeneity, meta-analysis was performed for one outcome with mean difference (MD) using Inverse Variance Method with Review Manager 5.4 software.Results: Out of the 242 articles with de-duplication and screening questions, 10 based on interventional studies among adult males with LUTS were selected in ??third round (8 on pumpkin seeds alone; 2 on pumpkin combined products). International Prostate Symptoms Score (IPSS) was described in nine articles. Other outcomes assessed were quality of life (QOL), prostate volume, Prostate Specific Antigen (PSA), uroflow rate, post-voidal residual volume, frequency of micturition during day and night, nocturia and erectile dysfunction. Meta-analysis of three studies (650 and 631 subjects in experimental and control groups) was performed for IPSS reduction. Pooled MD (I2=0%) was -1.41 (95% CI: -1.97, -0.85) with random effect assumption. In all relevant studies, the intervention group demonstrated significant IPSS reduction and increased QOL. One study each demonstrated significant reduction in prostate volume and residual volume; three studies in uroflow rate; and none on PSA improvement.Conclusions &amp; Recommendations: Pumpkin seeds may be beneficial in reducing IPSS and to some extent in improving prostate and residual volume, uroflow rate and QOL in BPH. Further studies are needed to strengthen the hypothesis.

Psychological guidance of Marxist spirit based on dialectical thinking for students with bipolar depression

BackgroundBipolar depression refers to bipolar disorder that occurs when depression and mania coexist. The onset of this disease is easily influenced by the patient’s negative attitude. Marxism under dialectical thinking has a good psychological guiding effect.Subjects and MethodsIn order to verify the psychological guidance effect of the Marxist spirit under dialectical thinking on students with bipolar depression, the study will select 80 students with bipolar depression for comparative experiments. The students are randomly divided into two groups, one group being a blank group, which only received traditional treatment. The other group is the experimental group, which adopts a combination of traditional treatment and Marxist spiritual education of dialectical thinking. The experimental period is 30 days. Before and after the experiment, patients filled out the Hamilton Depression Scale (HAMD) and Hamilton Anxiety Scale (HAMA). The psychological status of the two groups of experimental subjects was analyzed based on the results of the table.ResultsBefore the start of the experiment, the HAMA scores of the blank group and the experimental group were 16.52 ± 2.12 and 16.61 ± 1.89, respectively, and the HAMD scores were 17.46 ± 2.36 and 16.92 ± 3.21, respectively. After the experiment, the HAMA scores of the blank group and the experimental group were 14.56 ± 2.68 and 11.56 ± 3.15, respectively, and the HAMD scores were 14.76 ± 1.79 and 11.38 ± 2.73.ConclusionsUnder dialectical thinking, the Marxist spirit can improve the psychological state of students with bipolar depression.AcknowledgementThe 2021 project of the 14th Five-Year Plan for the Development of Philosophy and Social Sciences in Guangzhou City, Guangdong Province (No. 2021GZSZ16); The 2022 Party Building Research Project of Guangzhou Institute of Navigation (No. C2206001028).

Психофизиологические особенности взаимодействия с пугающим образом в виртуальной реальности

INTRODUCTION: Virtual reality (VR) technology, which is often used to generate situations of psychotherapeutic exposure, is presented to practitioners as a convenient visualization tool. However there is a risk of a distorted interpretation of the virtual experience by the client, in that case the stabilization of adaptive behavior and reduction of anxiety in contact with the object of the specified fear in the real world will not occur. AIM: To study the psychophysiological correlates of the emotional state arising in the situation of visual observation of a frightening virtual image. MATERIALS AND METHODS: As part of the study, a psychophysiological experiment was organized with the participation of 60 volunteers (10 boys, 50 girls, average age is 21) who made up experimental (persons with a history of identified fears) and control (conditionally healthy persons) samples. The experiment used controlled immersion of subjects in VR with a frightening virtual image with preliminary, accompanying and delayed removal of psychophysiological indicators of electroencephalogram and electrocardiogram, as well as using methods of psychodiagnostics. RESULTS: The study established the existence of a specific psychophysiological reaction in the experimental group of subjects in contact with a frightening virtual image represented as statistically marked fluctuations in heart rate and respiratory rate, as well as delta and alpha rhythms. In the subjects of the control group, this reaction is less marked and does not have a clearly defined specificity. CONCLUSIONS: The experience of interacting with a frightening virtual image when immersed in VR, according to the results obtained, is sufficiently consistent with the experience of interacting with a similar object in reality. The conclusion is made about the validity of the use of VR for the formation of correctional programs for working with anxiety-phobic symptoms.

Burnout prevention in healthcare professionals during COVID-19.

Burnout syndrome represents the pathological outcome of a stressful process that mainly affects the "helping professions". During the COVID-19 pandemic, pressure on healthcare systems has led to an increase in psychological distress among healthcare workers. The aim of this study is to verify whether the practice of relaxation techniques in healthcare workers can improve emotional balance and stem burnout. A small sample of 40 female rehabilitation therapists were divided into two groups (20 experimental group subjects and 20 control group subjects). The Maslach Burnout Inventory was administered to both groups, after informed consent, to highlight the correlation between working hours exceeding 30 hours per week and burnout, by subjecting the experimental group to mindfulness sessions between T0 and T1. The data analysis highlighted a decrease in burnout in the experimental group after the mindfulness sessions. The findings suggest that these relaxation techniques can be effective in stemming burnout and promoting psychological well-being. It is therefore possible to hypothesize that such increased and prolonged activities could show a more evident and statistically significant improvement.

Empowering Subject Matter Awareness through Exploratory Practice: Embracing Practitioner Research in the AI Era

A noteworthy challenge encountered among university EFL (English as a Foreign Language) learners lies in their deficiency pertaining to subject matter awareness, a crucial dimension of self-directed learning. This deficiency mainly hampers their ability to effectively deploy critical thinking strategies. This issue has been further exacerbated by the prevalent trend of students heavily relying on Artificial Intelligence (AI) tools for various educational tasks. To address this multifaceted challenge, this experimental research was conducted within a Lebanese English medium university. The core objective of the study was to cultivate students' subject matter awareness by integrating the Exploratory Practice [EP] instructional approach into their writing classes. The research encompassed two distinct groups: an experimental group and a control group. In-depth exploration was pursued using a mixed-methods approach. The outcomes of the study highlighted a significant transformation within the experimental group's subject matter awareness. In conclusion, this study underscores the imperative of nurturing students' subject matter awareness. Through skillful incorporation of EP into writing classes, educators can cultivate a revitalized sense of self-directedness and cultivate critical engagement within learners. This strategic integration not only equips them with essential skills but also empowers them to navigate the complex educational landscape infused with AI.

An experimental study of the carbohydrate exchange method combined with aerobic exercise to intervene in the physical health of obese college students

Abstract The purpose of investigating the carbohydrate exchange method in combination with aerobic exercise for obese college students is to help college students have better bodies to cope with their academic life. This paper introduces the qualitative and quantitative analysis technique based on near-infrared spectroscopy, starting from the analysis of the carbohydrate exchange method, and explains the physical, mathematical, and chemical information bases, respectively. A NIR detection model is constructed using the NIR spectroscopy detection method, and the main evaluation indexes of the model are given. Three experimental groups, namely, carbohydrate exchange method, aerobic exercise, and carbohydrate exchange method combined with aerobic exercise were set up to investigate the physical health interventions for obese college students. In the single test, the FPG, BUN, TC, and HbA1c values of the subjects in the carbohydrate exchange experiment group were reduced by 18.61%, 17.33%, 11.09%, and 18.16%, respectively. The FPG, BUN, TC, and HbA1c values were reduced by 23.42%, 18.84%, 11.62%, and 13.48%, respectively, in subjects in the aerobic exercise experimental group. From the carbohydrate exchange method combined with the aerobic exercise experimental group, the subjects’ FPG, BUN, TC, and HbA1c values were reduced by 28.38%, 22.24%, 11.27%, and 27.4%, respectively, which was a better level of intervention than the single experimental group. Thus, the carbohydrate exchange method combined with aerobic exercise can be an effective intervention for the physical health of obese college students.

Natural Remedy in Reduction of Morning Sickness among Antenatal Women

Natural remedy in reduction of morning sickness among antenatal women ABSTRACT Nausea and vomiting of pregnancy is a condition with significant adverse effects on health of mother and fetus that warrants recognition, investigation and treatment. Morning sickness is believed to be due to high levels of pregnancy hormones secreted by placenta. Objectives of the study was to assess the severity of morning sickness for antenatal women in experimental and control group and to assess the effectiveness of natural remedy in reducing the severity of morning sickness. An experimental research was done with 40 antenatal women, in first and second trimester, attending outpatient department in K. G Hospital, Coimbatore, and were divided into experimental and control group. Purposive sampling technique was adopted for the study. Data collection was done by using a self-designed structured questionnaire and modified Rhodes index scale. The experimental group subjects were provided with 250 mg of powdered ginger and half teaspoon honey, given four times daily for 4 days. The severity of morning sickness was reassessed after the treatment. Control group subjects received only routine care. Analysis was done by descriptive and inferential statistics. Results showed there is a significant difference between the pre test score and post test score on severity of morning sickness among experimental group subjects ( t=17.83). After consuming ginger the severity of morning sickness was reduced in experimental group when compared to control group (Z=9.4). Thus the study is concluded that consumption of ginger reduces the severity of morning sickness among antenatal women.

Maximal oxygen uptake prediction from submaximal bicycle ergometry using a differential model

The maximal oxygen uptake (VO2max) estimation has been a subject of research for many years. Cardiorespiratory measurements during incremental tests until exhaustion are considered the golden yard stick to assess VO2max. However, precise VO2max determination based on submaximal tests is attractive for athlete as well for clinical populations. Here, we propose and verify such a method based on experimental data. Using a recently developed model of heart rate (HR) and VO2 kinetics in graded exercise tests, we applied a protocol, which is terminated at 80% of the estimated maximal HR during ergometer cycling. In our approach, initially, formula for maximal HR is selected by retrospective study of a reference population (17 males, 23.5 ± 2.0 years, BMI: 23.9 ± 3.2 kg/m2). Next, the subjects for experimental group were invited (nine subjects of both sexes: 25.1 ± 2.1 years, BMI 23.2 ± 2.2 kg/m2). After calculation of maximal HR using cardiorespiratory recordings from the submaximal test, VO2max is predicted. Finally, we compared the prediction with the values from the maximal exercise test. The differences were quantified by relative errors, which vary from 1.2% up to 13.4%. Some future improvements for the procedure of VO2max prediction are discussed. The experimental protocol may be useful for application in rehabilitation assessment and in certain training monitoring settings, since physical exertion is not a prerequisite and the approach provides an acceptable VO2max estimation accuracy.

Research on the innovation path of teaching interior design majors in universities based on big data analysis

Abstract Presently, the teaching of interior design in most higher education institutions still uses more traditional and conservative teaching methods, which to some extent, hinders the reform of interior design teaching in the era of big data. Interior design originally required students to grasp the operation fully and use CAD, 3D, and other design software, which makes the operation of complex commands, and model construction diversity, difficult for students to learn. This situation still uses the traditional lecture-based indoctrination teaching can play a very small role. This paper first focuses on the field of interior design education, based on the background of the times, provides a deep overview of the current situation of the relevant research involved in interior design, and explains the purpose, ideas, content, and methods of this paper. Secondly, we use data mining technology to build a smart classroom to visually present interior design. Finally, a comparison experiment between the traditional teaching mode of interior design and the smart teaching mode of big data is carried out, and three groups of experimental subjects are investigated after nearly one month of teaching experience. The results of this study show that the big data wisdom teaching model proposed in this paper compared with the traditional teaching model, through the one-month teaching experience post-test results, the average increase of 7 points in school A, 11 points in school K, and 14 points in school Z. The wisdom teaching system based on big data built in this paper enhanced the relevance and initiative of interior design students’ learning, improved students’ interest in learning and classroom efficiency and promoted students’ comprehensive ability while playing a positive and active role.
