ABSTRACT
Background: The STarT (Subgrouping for Targeted Treatment) Back Screening Tool (SBST) is an established clinical evaluation tool that easily assesses the risk of chronic or refractory low back pain. This study aimed to examine the usefulness of acupuncture in patients with low back pain. Methods: A total of 71 outpatients with low back pain who underwent acupuncture and moxibustion at the Center for Integrative Medicine, Tsukuba University of Technology, between 2019 and 2022 were included in this study, regardless of the specific medical condition causing the pain. Survey items included the SBST and lumbar pain intensity visual analog scale (VAS). Demographic factors and contents of acupuncture treatment were collected from the medical charts. The VAS score 4 weeks after the start of treatment was used as an index of clinical outcome and was analyzed using repeated measures analysis of variance (ANOVA) and hierarchical multiple regression analysis. Results: Classification using the SBST at the first visit resulted in 36, 30, and 15 patients in the low-, medium-, and high-risk groups, respectively. Repeated-measures ANOVA showed statistically significant differences in the mean VAS values with respect to differences in time point (P < 0.01), group (P < 0.01), and interaction (P < 0.05). The VAS values after 4 weeks in the high-risk group were significantly higher than those in the other two groups (both P < 0.01). In the hierarchical multiple regression analysis, with VAS as the dependent variable, the relationship between SBST classification and VAS maintained a significant positive relationship in all models, including adjustments for interaction terms and patients’ background items. A simple slope analysis indicated that this relationship was more evident in patients with lower limb symptoms than in those without symptoms. Conclusion: The SBST could be a simple and useful tool for predicting the clinical outcomes of acupuncture.
ABSTRACT
The study was carried out in four different agro-climatic zones of Maharashtra. A typology was developed applying multivariate statistical techniques i.e. Cluster analysis (CA) to classify groups of farm households with similar farm characteristics into four homogenous clusters, (i) households possessing small landholding, a larger high yielding dairy stock with small goat flock size (37.5%), (ii) households having small landholding with a small stock of high yielding dairy animal and small goat flock size (39%), (iii) households having large landholding with large high yielding dairy stock and small flock size (13.5%) and (iv) households possessing small landholding with small high yielding dairy stock and large flock size (10%). An assessment in terms of awareness, knowledge and adoption of dairy technologies and goat production practices were carried out across the clusters which was found significantly high within the household of cluster 3 and 4. The overall adoption index was found to be 65.16 per cent across the whole clusters. Multiple regression analysis revealed that total SAU, flock size, occupation, innovative proneness, scientific orientation, awareness of technology and knowledge of technology contribute positively (P<0.01, P<0.05) to the adoption of technology. The coefficient of determination was found (R2 =0.66) across the whole clusters
ABSTRACT
OBJECTIVE： To study direct medical expense and its influential factors， and to provide empirical reference for medical expenses control of pulmonary embolism and the adjustment of anticoagulant drug reimbursement strategy. METHODS： Based on the national urban basic medical insurance data in 2014， the data of patients with pulmonary embolism were extracted by equidistant sampling method to form a sample database. According to related therapy information and expense information of pulmonary embolism patients in sample database， descriptive analysis was performed for demographic characteristics of patients （including gender， age， type of medical insurance， region， type of medical institution， etc.）， direct medical expenses and direct medical expenses of patients with different anticoagulants， etc. Multiple linear regression analysis was used to analyze potential influential factors for the medical expenses of patients. RESULTS： A total of 475 pulmonary embolism patients were included， a total of 1 090 visits were recorded， and the average length of stay was 12.37 days. The annual medical expense per capita of patients was 10 847.42 yuan （median was 4 113.00 yuan）， hospitalization expense per capita was 19 056.30 yuan （median was 13 042.86 yuan）， and outpatient expense per capita was 1 049.61 yuan （median was 418.70 yuan）. Results of subgroup analysis showed that annual medical expense in eastern， central and western cities were 9 203.54， 16 931.99 and 15 891.21 yuan. Per capita annual medical expenses of patients in tertiary hospitals were the highest （11 733.40 yuan）， followed by secondary hospitals， and the lowest was other medical related institutions. Among different anticoagulants treatment groups， the annual medical expense per capita （24 553.80 yuan） and annual drug expense per capita （12 088.96 yuan） were the highest in anticoagulant regimen of combined use of LMWH and UFH， while patients treated with warfarin alone had the lowest annual medical expense per capia （2 350.24 yuan） and annual drug expense per capita （1 163.67 yuan）. The multiple linear regression showed that the factors affecting medical expense per visit were type of patient （inpatient or outpatient），type of medical institution and type of complications. CONCLUSIONS： Direct medical expense per capita of patients with pulmonary embolism is still high， and the economic burden of disease is still heavy. Patients with pulmonary embolism treated with combination of LMWH and UFH had the highest medical expense per capita. The types of visit， types of medical institutions and complications can influence medical expense of patients significantly.
ABSTRACT
OBJECTIVE :To introduce two commonly used algorithms for warfarin individualized medication——multiple regression analysis(MRA)and maximum a posterior Bayesian (MAPB), and provide reference for individualized medication of warfarin in clinical practice. METHODS: The principles of MRA and MAPB for warfarin individualized medication, as well as the decision support tools to realize MRA and MAPB, were introduced. The function of MAPB tool, including formulating an initial dosage regimen, adjusting the regimen and its application in special clinical situations, was described by five typical cases.RESULTS AND CONCLUSION :MLR is simple to calculate, however, it can only be used to formulate the initial dosage regimen and dose adjustment cannot be carried out, which limits it clinical application in a certain extent. The application of MAPB can not only develop individualized medication of warfarin and adjust dose according to international normalized ratio(INR) with satisfactory prediction performance, but also be applied in special cases with better flexibility, such as judging medication adherence and instructing withdrawal. It could serve as an effective decision support tool to be promoted vigorously, which has a promising prospect.
ABSTRACT
<p>Decreased adherence to medications among the elderly has become a problem in recent years. To overcome this problem, the dispensing of one-dose packages of medicines has been suggested. The purpose of this study was to survey elderly outpatients in a regional hospital at the Tokachi Development and Promotion Bureau and to analyze the factors that influence patients’ preference for a one-dose package medicine. The dispensation of one-dose package medication was observed in 20% of elderly outpatients. A correlation between the percentage of dispensed one-dose package medications and the number of agents was observed. Furthermore, dispensing rates of one-dose package medications increased with aging. Within the various departments analyzed, one-dose packaging rate was high in the Departments of Cardiology and Psychiatry. In this study, the correlation between residential municipalities of outpatients and one-dose package medications was examined. In the municipalities with a high rate of aged individuals and high average of household members, one-dose package medication rate was low. Multivariate logistic regression analysis confirmed these factors as significant. That one-dose packaging rates increased with the number of drugs and aging are consistent with the notion that one-dose package medications are designed to increase drug adherence among the elderly. Interestingly, one-dose package dispensing rate was low in areas with advanced aging. Because aging in Japan is expected to advance in the future, it is important to survey one-dose package dispensations.</p>
ABSTRACT
Epimedium is a widely used medicinal plants. Due to excessive use of wild resources and resource constraints, artificial cultivation is the only way to achieve sustainable use of resources. E. pseudowushannense is intended to achieve the first cultivated species, but plant production technology is not yet fully mature.The diurnal variation of photosynthetic and eco-physiological characteristics of E. pseudowushannense in different growing age was studied by the CI-340 Portable Photosynthesis System under natural conditions. The net photosynthetic rate (Pn), stomatal conductance (C), intercellular CO2 concentration (Ci), photosynthetically active radiation (PAR), relative humidity (RH), air temperature (Ta), apparent mesophyll conductance (ALMC), transpiration rate (E), leaf temperature (Tl), water use efficiency (WUE) and other photosynthetic physiological factors and environmental factors were measured. The obtained data was analyzed by correlation analysis, path analysis and stepwise multiple-regression analysis to explore the relationship between net photosynthetic rate and physiological and ecological factors. The results show that： ①The daily variation of the Pn, E, ALMC, C of E. pseudowushannense in different growing age took on"two peak type", the Pn was with an obvious midday depression phenomenon at noon.②The Pn, ALMC and C of annuals' were significantly higher than biennial or three-year; but the Ci was basically a three-year > biennial> annual.③The correlation analysis, path analysis and stepwise regression analysis showed that ALMC, Ci, Ta might played important role in the Pn and ranked as ALMC>Ci>Ta.
ABSTRACT
The degree of parasite aggregation is determined by a number of factors that are not well understood. In total, 3,746 fish from 73 species and their parasites were analyzed to determine associations between the degree of aggregation by taxon and specific characteristics of the fish. A multiple linear regression (95% confidence interval - CI) was used to show that in most taxa, the degree of parasite aggregation was significantly higher in freshwater fish and schooling fish but varied according to taxon in relation to gender, habitat and feeding habits. Parasite aggregations were also significantly increased in fish with a large number of parasitic larvae and greater body length in all evaluated taxa. Because the coefficients of determination of the models were lower than 60% for all taxa, other factors may be involved in parasite aggregation. Conversely, marked significance was observed for the tested variables in relation to taxon dependence, which indicates that additional studies should be performed for these factors using comprehensive databases with larger samples per parasite species.
O nível de agregação parasitária é determinado por um conjunto de fatores não muito bem elucidados. Foram analisados 3.746 peixes pertencentes a 73 espécies e seus respectivos parasitos, com o objetivo de verificar a associação entre o nível de agregação por táxon e algumas características dos peixes. Por meio da técnica de regressão linear múltipla (IC 95%), observou-se que o nível de agregação de parasitos foi significativamente maior em peixes dulcícolas e formadores de cardume, na maioria dos táxons, mas variou conforme o táxon em relação ao sexo, o hábitat e o hábito alimentar. A agregação parasitária também aumentou significativamente em peixes com maior proporção de larvas parasitas e com maior comprimento do corpo em todos os táxons avaliados. Tendo em vista que os coeficientes de determinação dos modelos para todos os táxons foram inferiores a 60%, outros fatores podem estar envolvidos na agregação de parasitos. Por outro lado, as variáveis testadas assumem importância diferenciada na dependência do táxon, sinalizando para a necessidade de se continuar pesquisando esses fatores em bancos de dados mais abrangentes e com amostras maiores por espécies de parasitos.

The purpose of this study is to examine the predictive role of self- compassion on entrapment. Participants were 338 university students (185 women, 153 men; M age = 20.5 yr.). In this study, the Self-compassion Scale and the Entrapment Scale were used. The relationships between self-compassion and entrapment were examined using correlation analysis and multiple regression analysis. In correlation analysis, self-kindness, common humanity, and mindfulness factors of self-compassion were found negatively and self-judgment, isolation, and over-identification factors of self-compassion were found positively related to entrapment. According to regression results, entrapment was predicted positively by self-judgment, isolation, and over-identification. Further self-kindness and common humanity predicted entrapment in a negative way. Self-compassion has explained 50% of the variance in entrapment. The results were discussed in the light of the related literature and dependent recommendations to the area were given.

Regression AnalysisABSTRACT
There are few studies that have examined the role of self-compassion in the context of social life, while self-compassion appears to enhance interpersonal relationship skills. The purpose of this study is to examine the predictive role of self-compassion on social safeness. Participants were 401 university students (213 women, 188 men; M age= 20.5 yr.). In this study, the Self-compassion Scale and the Social Safeness and Pleasure Scale were used. The relationships between self-compassion and social safeness were examined using correlation analysis and multiple regression analysis. In the correlation analysis, self-kindness, common humanity, and mindfulness factors of self-compassion were found to be positively related, and self-judgment, isolation, and over-identification factors of self-compassion were found to be negatively related to social safeness. According to regression results, social safeness was predicted positively by mindfulness, self-kindness, and common humanity. Further isolation predicted social safeness in a negative way. The regression model explained 28% of the variance in social safeness. Together, the findings illuminate the importance of self-compassion on social adjustment. The results are discussed in the light of the related literature.

ABSTRACT
Objective : This study aimed to investigate the changes in the functioning of users of visiting rehabilitation services and related factors. Methods: Among 107 users in 22 visiting rehabilitation centers, we analyzed the data of 80 who completed the 6-month study. Their Functional Independence Measure (FIM), Life-Space Assessment (LSA), and level of caregiver burden (J-ZBI_8) were compared at the commencement of this study, and at 3 and 6 months afterwards. A multiple linear regression analysis was performed to examine the factors related to the variables, which changed over 6 months. Results : Over a period of 6 months from the commencement of the study, we found that FIM and LSA scores significantly improved from 82.4 to 87.3 (<i>p</i>=0.016) and from 9.9 to 12.3 (<i>p</i>=0.05), respectively, in the group who were still within 1 year from the time since onset/injury. A multiple regression analysis revealed that the period of time since onset/injury, independence degree of daily living for the demented elderly, and presence of goal setting for activities of daily living/domestic work significantly influenced changes in total FIM scores (<i>p</i>=0.001, <i>R</i><sup>2</sup>=0.32). Furthermore, the change in LSA scores was significantly influenced by gender, presence of cerebrovascular diseases, period of time since onset/injury, number of occupations involved in visiting rehabilitation services, and J-ZBI_8 scores (<i>p</i>=0.0001, <i>R</i><sup>2</sup>=0.36). Conclusion : Effective visiting rehabilitation requires having appropriate goals set for daily living activities and the establishment of interprofessional collaboration within visiting rehabilitation centers.

ABSTRACT
This paper focuses on the applications of multivariate statistical techniques for designing cost-effective, low non-target nerve-damageable organophosphorus pesticides (OPs) used in Indian agriculture. The study was done with regard to the effect of seven OPs on acetylcholinesterase (AChE) activity in four different parts of rat brain: hypothalamus (H), striatum (S), cerebellum (CR), and cerebrum (C). Not all the parts of mammalian brain are equally sensitive to the same pesticide as was evident by direct plotting of inverse of AChE activity versus inverse of LD50 (lethal dose), and that of AChE activity versus Pow values. The nature of dependence of AChE activity on the pesticide (Pow i.e., octanol water partition coefficient values) and LD50 was determined by multiple regression analysis (MRA). This was supported by multiple correlation coefficient values, which indicate the measure of efficacy for different predicting equations. In most of the cases, the results appeared satisfactory. Thus, using MRA, model pesticides can be designed which are less toxic to non-target organisms such as mammals.
ABSTRACT
Objective To investigate the quality of life(QOL)of patients with stroke and its related factors.Methods The QOL of eighty-two stroke survivors was assessed in terms of SF-36 scores,motor impairment (Fugl-Meyer),disability[Barthel index(BI)]and depression(HAMD)more than one year after their first episode.Their social demographic characteristics such as age,gender,education and income were recorded,as were the characteristics of their disease and any complications.Multiple regression analysis was used to analyse the related factors.Results The average age of the 82 subjects was 61.89 + 9.81 years(range,33-81).56 of them were male (68.2％).Scores on all items of the SF-36 for these subjects were lower than those of a normal population.Correlation analysis showed income,cost for medical care,regular exercise,movement function,ability in the activities of daily living,depression,hypertension and shoulder pain were significantly correlated with most of the SF-36 domain scores.Motor function,income and cost for medical care explained 34％ of the variance in SF-36 scores.Motor function was the single most important factor.Conclusion The major factors affecting the QOL of stroke patients are motor function,level of income and cost for medical care.Paying more attention to rehabilitation treatment,taking regular exercise and more income could help improve the QOL of stroke survivors.
ABSTRACT
1)The factors Japanese residents consider most important in postgraduate clinical training are: "relationship with supervising physicians," "well-developed training programs," and "guidance of supervising physicians."2)Items showing a large discrepancy between their importance to residents and residents' satisfaction were: "well-developed training program," "experiencing a large number of cases,""guidance of supervising physicians," and "guidance of senior residents."3)Multiple regression analysis showed that factors significantly influencing residents' satisfaction with training were "quality of the medical service" (r=0.59) and "consideration for accepted residents" (r=0.42).
ABSTRACT
We evaluated the efficacy of chotosan for headache patients via multiple regression analysis. The subjects were 46 patients with headache (31 migraine, 14 tension-type, and1combination headache), consisting of 1 3males and 33 females, mean age 48 years (range 19-77 years), who were treated with chotosan according to their Sho (symptoms) for more than1month. The relationships between the improvement of headache and 38 factors, including age, sex, height, body weight, hypertension and other symptoms noted upon first medical examination, were examined through multi-dimensional cross-sectional analysis. Morning headache, dizziness, insomnia, body weight, tinnitus and vasodilatation of sublingual veins were significant factors. Morning headache is traditionally an indication for the use of chotosan, and our results support its efficacy for this purpose. Three factors, i.e. morning headache, vasodilatation of sublingual veins and stiff shoulder, were the best subset of explanatory variables. Stiff shoulder is a key symptom for the application of chotosan, while stiffness in the back is a key symptom for the application of yokukansan.
