It affects not only the well-being of workers but also the firms and society as a whole through medical costs and productivity losses due to absenteeism and presenteeism. Data and Methods: Data were obtained from 1136 employees at an operational site of a large corporation. The dataset contained both medical checkups and working record information. Health factors affecting long-term absence (over three days in three months) were analyzed. Logistic regression models and the procedure for selecting proper covariates based on likelihood test statistics and the Akaike information criterion were used. Results: Among health factors, high-density lipoprotein cholesterol (HDL-C) and blood sugar levels were important in the selected model. For HDL-C, the odds ratio (OR) based on one standard deviation difference was 0.75 with a 95% confidence interval (CI) of 0.59 - 0.95. For blood sugar, the OR was 1.20 with a 95% CI of 1.01 - 1.42. Improving HDL-C and blood sugar levels would reduce long-term absence by 25% and 20%, respectively. Conclusion: Controlling HDL-C and blood sugar levels is important to reduce long-term absenteeism. These factors can be improved by modifying eating habits. Since the operational site has its own company cafeterias, which most employees use, nutritional intervention is relatively easy with little or no cost. It may be worthwhile to implement nutritional intervention, especially for patients with low HDL-C or high blood sugar levels. Limitations: The results of this study were based on one operational site of a corporation. The employees were mainly operators working inside the building. The results may be different from other types of jobs and working conditions, such as fieldwork. Analyses of different types of jobs and working conditions are necessary.展开更多

In this study the effects of consumption of raw garlic on serum lipid level, blood sugar and a number of effective hormones on lipid and sugar metabolism (thyroid hormones and insulin) in individuals either with high level of blood sugar or lipid were investigated. Eighty five volunteers having following clinical history enrolled in the study: Group 1: having blood sugar more than 126 mg/dl (30 vo-lunteers);Group 2: having cholesterol higher than 245 mg/dl (30 volunteers);Group 3: having blood sugar over 126 mg/dl and cholesterol more than 245 mg/dl (25 volunteers). In group 1, there wasn’t a sig-nificant differences between biochemical factors be-fore and after garlic consumption, whereas, in the second group after 6 weeks of garlic consumption a decline in cholesterol (P < 0.001), FBS and TG (P < 0.01) was observed but HDL-C (P < 0.001) was in-creased. Six weeks after termination of garlic con-sumption, cholesterol (P < 0.001), FBS and TG (P < 0.05) were in- creased and HDL-C (P < 0.01) was de-creased. In the third group, total cholesterol (P < 0.001), FBS (P < 0.01) and HbA1c decreased while HDL-C was in- creased. Other factors, including thy-roid hormones (T3, T4), TSH and insulin showed no significant alte- ration. In conclusion our results shown that raw garlic consumption can reduce the FBS and Lipid in hyperglycemic and/or hyperlipidemic individuals.展开更多

Methods: A total of 120 inpatients and outpatients were randomly divided into acupuncture plus medication group (n=52) and medication group (n=50). In addition, 18 type II diabetes patients formed acupuncture group for comparing their therapeutic effects. Main acupoints used were Pishu (BL 20), Geshu (BL 17), Yishu, Shenshu (BL 23), Zusanli (ST 36), Sanyinjiao (SP 6), etc.. combined with other acupoints according to different sydroms. These acupoints were stimulated by manipulaing the filiform needles with uniform reinforcing and reducing method for 15 min and then stimulated electrically for 15 min with an electroacupuncture therapeutic apparatus. Western medicines used were Glipizide, Dimethyldiguanide Hydrochloride, etc.. The treatment was given once daily, with 10 sessions being a therapeutic course, 2～3 courses altogether. Indexes of external thrombosis length (ETL), platelet agglutination rate (PAgR), fibrinogen (FG), activated partial thromboplastin time (APTT), fasting blood glucose (FBG), prothrombin time(PT), adrenocoticortropic hormone (ACTH), cortisol (CS), growth hormone (GH), glucagon (GL), tumor necrosis factor alpha (TNF α), interleukin 6 (IL 6), insulin (INS) and C peptide (C P) were determined using radioimmunoassay. Results: After 2～3 courses of treatment, both acupuncture group and medication plus acupuncture group could significantly improve high hemagglutination state, lower blood sugar raising hormone level, regulate immunocyte factor level and raise the sensitivity of insulin, which were apparently superior to those of medication group (P<0.05～0.01). Conclusion: Acupuncture therapy can effectively regulate plasma blood sugar raising hormone, immunocyte factor levels, increase the sensitivity of insulin to target cells, resist blood coagulation and improve microcirculation.展开更多

Another important, recently developed technique is blood oxygen level–dependent functional magnetic resonance imaging(BOLD-fMRI), which utilizes hemoglobin as an endogenous contrast agent and measures deoxygenated hemoglobin content by sampling the oxygen content of tissues, thus reflecting the hemodynamics and pathophysiologic changes in body organs. Currently this technology is being used in patients with liver tumors;that is, it serves as an important tool in follow-up after TACE. The present paper summarizes these developments.展开更多

Tremor, rigidity, and bradykinesia are the major symptoms of the disease. These motor impairments are often accompanied by affective and emotional dysfunctions which have been largely studied over the last decade. The aim of this study was to investigate emotional processing organization in the brain of patients with Parkinson's disease and to explore whether there are differences between recognition of different types of emotions in Parkinson's disease. We examined 18 patients with Parkinson's disease(8 men, 10 women) with no history of neurological or psychiatric comorbidities. All these patients underwent identical brain blood oxygenation level-dependent functional magnetic resonance imaging for emotion evaluation. Blood oxygenation level-dependent functional magnetic resonance imaging results revealed that the occipito-temporal cortices, insula, orbitofrontal cortex, basal ganglia, and parietal cortex which are involved in emotion processing, were activated during the functional control. Additionally, positive emotions activate larger volumes of the same anatomical entities than neutral and negative emotions. Results also revealed that Parkinson's disease associated with emotional disorders are increasingly recognized as disabling as classic motor symptoms. These findings help clinical physicians to recognize the emotional dysfunction of patients with Parkinson's disease.展开更多

Screening the general population has debatable advantages. This study aims to determine whether spouses of patients with diabetes mellitus have higher random blood glucose (RBG) levels as well as the benefit of RBG testing as a targetted screening tool. Methodology: The survey employed a cross-sectional comparative study of spouses’ of diabetics and non-diabetics attending the general out-patient department of the LagosStateUniversityTeaching Hospital (LASUTH), Ikeja. A modified WHO STEPS Surveillance Instrument and a one-touch Glucometer were used to collect data. Blood pressures and BMI were measured and correlated to blood glucose levels. Results: Prevalence of high RBG was found to be 7% among spouses of diabetics and 3.3% among spouses of non-diabetic patients. Mean RBG was 5.57 mmol/L and 7.7 mmol/L within the age group 40 - 49 years and 50 - 59 years respectively among spouses of diabetic patients compared to 5.4 mmol/L and 5.5 mmol/L within the same age group among the spouses non-diabetics. Spouses of patients with diabetes mellitus had higher systolic and diastolic blood pressures and BMI compared to spouses of non-diabetics. Conclusion: Being male, married to a diabetic patient, lower educational levels and higher body mass index are significantly associated with higher random blood glucose in the spouses of diabetic patients. Random blood glucose measurements are an effective screening tool and spouses of diabetic patients can benefit from targeted screening in controlled clinical settings.展开更多

It is important to know the prevalence of diabetes, the factors affecting blood glucose levels, and the percentage of people with diabetes taking medications. Data and Methods Data and Methods: We analyzed the distribution of blood glucose levels and prevalence of diabetes using 10,917,173 observations obtained from the JMDC Claims Database in Japan. The factors that may affect blood glucose levels were analyzed by a regression model using 5,472,205 observations. Treatment with diabetes medications was analyzed with 9,932,854 and 5,466,361 observations using a method to approximate the inverse of probability by a continuous piecewise linear function. Results: The prevalence of diabetes in 2019 was estimated to be 9.63% in males and 5.33% in females ages 20 - 79;10.78% and 7.04% for ages 20 - 89;and 10.93% and 7.65% for ages 20 - 99, respectively. In addition to age and gender, the important variables affecting blood glucose levels were <em>BMI</em>, <em>SBP</em>, <em>Triglyceride</em>, <em>ALT</em>, <em>AST</em> and <em>GGP</em>. The percentage taking medications increased up to a blood glucose level of around 175 mg/dL, but declined over that. Conclusion: The prevalence of diabetes in Japan was estimated using a very large dataset, and considering age, gender, and time trends. Some variables may be effective for controlling blood glucose levels. Nearly half of those at a serious stage of diabetes took no medications. Proper medical care for these individuals is necessary to prevent worsening diabetes and serious complications. Limitations: The dataset was observatory, and did not include those age 80 or over. Revising medical care systems to include those outside of hospitals is necessary;however, practical approaches have not yet been developed.展开更多

Ante- and intrapartum cardiotocography (CTG) examination could lead to a false positive diagnosis of asphyxia (fetal distress). Troponin I (TnI) is an important factor to the pathogenesis of asphyxia. Cord blood TnI level is increased in infants with fetal cardiac dysfunction, causing pathological CTG and low APGAR score (<7). In the future, TnI is expected to reduce false positive diagnosis of asphyxia caused by CTG. This research was conducted to examine and analyze the differences of cord blood TnI level between normal and asphyxiated infants and to determine the correlation between TnI level and APGAR score. An observational analytical cross sectional study was conducted to a total of 36 patients with asphyxiated infants (18 patients) and normal infants (18 patients). Subjects were selected according to the inclusion and exclusion criteria. Cardiotocography, TnI level, and APGAR score were examined. Umbilical cord blood samples were taken from each subject for the measurement of TnIlevel using a highly sensitive indirect sandwich Enzyme Linked Immunosorbent Assay (ELISA). Statistical analysis was performed by Mann-Whitney and Rank Spearman correlation coefficient test. Cord blood TnI level of asphyxia andnormal groups were 1615.77 ± 1199.98 pg/mL and 819.88 ± 145.82 pg/mLrespectively (p ≤ 0.05). Rank Spearman correlation coefficient between cord blood TnI level and 1’ and 5’ APGAR score was -0.523 (p = 0.026;p ≤ 0.05)and -0.502 respectively (p = 0.034;p ≤ 0.05). There was a statistically significant difference between cord blood TnI level of asphyxia and normal groups;cord blood TnI level of asphyxia group was higher than normal group. Furthermore, negative correlation was observed between cord blood TnI level and APGAR score.展开更多

Cortex Lycii is an herb from Asia mostly used in traditional Chinese medicine. Although its main purpose is not for lowering blood glucose levels, there are studies on Cortex Lycii with other substances which have proven it can lower glucose level in type 2 diabetes rat. Unlike other experiments, this experiment only used Cortex Lycii as a single unit to see if there was any effect on blood glucose level. Also an observation was done on if Cortex Lycii could reduce blood glucose level after ingesting a high glucose diet. Rattus norvegicus was used in this project and in order for the subject to consume Cortex Lycii, the herb was boiled and the liquid was given for consumption. In order to increase the rats’ glucose levels, corn syrup and white sugar were added to the mixture. The data showed significant decrease of blood glucose when Cortex Lycii liquid was ingested. This research has shown that Cortex Lycii can be a potential treatment for hyperglycemia or diabetes. With further research, there can be an alternative treatment rather than injecting external hormones (Insulin).展开更多

In typeI diabetes, because of the lack of insulin secretion, the cells cannot absorb glucose, and thus have a low level of glucose. To control blood glucose, the insulin must be injected to the body. In fact, the injection must be in a completely controlled environment. If the level of the insulin exceeds the physiological limits, it may cause death. This paper presents an online approach to control the blood glucose level using a nonlinear model predictive control. This method, maintains the level of blood glucose concentration within a normal range. Thus, the blood glucose level is measured in each minute and predicted for the next time interval. If that is not in the normal range, amount of the insulin which must be injected will be determined. The proposed control approach includes important features such as model uncertainties and prevents acute decrease in the blood glucose level, and instability. In order to assess performance of the proposed controller, computer simulations have been carried out in Matlab/Simulink. Simulation results will reveal the effectiveness of the proposed nonlinear model predictive controller in adjusting the blood glucose level by injecting required insulin. So if the nutrition of the person decreases instantly, the hypoglycemia does not happen.展开更多
文摘Background: Workers’ health condition is an important issue. It affects not only the well-being of workers but also the firms and society as a whole through medical costs and productivity losses due to absenteeism and presenteeism. Data and Methods: Data were obtained from 1136 employees at an operational site of a large corporation. The dataset contained both medical checkups and working record information. Health factors affecting long-term absence (over three days in three months) were analyzed. Logistic regression models and the procedure for selecting proper covariates based on likelihood test statistics and the Akaike information criterion were used. Results: Among health factors, high-density lipoprotein cholesterol (HDL-C) and blood sugar levels were important in the selected model. For HDL-C, the odds ratio (OR) based on one standard deviation difference was 0.75 with a 95% confidence interval (CI) of 0.59 - 0.95. For blood sugar, the OR was 1.20 with a 95% CI of 1.01 - 1.42. Improving HDL-C and blood sugar levels would reduce long-term absence by 25% and 20%, respectively. Conclusion: Controlling HDL-C and blood sugar levels is important to reduce long-term absenteeism. These factors can be improved by modifying eating habits. Since the operational site has its own company cafeterias, which most employees use, nutritional intervention is relatively easy with little or no cost. It may be worthwhile to implement nutritional intervention, especially for patients with low HDL-C or high blood sugar levels. Limitations: The results of this study were based on one operational site of a corporation. The employees were mainly operators working inside the building. The results may be different from other types of jobs and working conditions, such as fieldwork. Analyses of different types of jobs and working conditions are necessary.

文摘Diabetes mellitus is one of the worldwide largest growing metabolic diseases. In this study the effects of consumption of raw garlic on serum lipid level, blood sugar and a number of effective hormones on lipid and sugar metabolism (thyroid hormones and insulin) in individuals either with high level of blood sugar or lipid were investigated. Eighty five volunteers having following clinical history enrolled in the study: Group 1: having blood sugar more than 126 mg/dl (30 vo-lunteers);Group 2: having cholesterol higher than 245 mg/dl (30 volunteers);Group 3: having blood sugar over 126 mg/dl and cholesterol more than 245 mg/dl (25 volunteers). In group 1, there wasn’t a sig-nificant differences between biochemical factors be-fore and after garlic consumption, whereas, in the second group after 6 weeks of garlic consumption a decline in cholesterol (P < 0.001), FBS and TG (P < 0.01) was observed but HDL-C (P < 0.001) was in-creased. Six weeks after termination of garlic con-sumption, cholesterol (P < 0.001), FBS and TG (P < 0.05) were in- creased and HDL-C (P < 0.01) was de-creased. In the third group, total cholesterol (P < 0.001), FBS (P < 0.01) and HbA1c decreased while HDL-C was in- creased. Other factors, including thy-roid hormones (T3, T4), TSH and insulin showed no significant alte- ration. In conclusion our results shown that raw garlic consumption can reduce the FBS and Lipid in hyperglycemic and/or hyperlipidemic individuals.

文摘Parkinson's disease is a neurodegenerative disorder caused by loss of dopamine neurons in the substantia nigra pars compacta. Tremor, rigidity, and bradykinesia are the major symptoms of the disease. These motor impairments are often accompanied by affective and emotional dysfunctions which have been largely studied over the last decade. The aim of this study was to investigate emotional processing organization in the brain of patients with Parkinson's disease and to explore whether there are differences between recognition of different types of emotions in Parkinson's disease. We examined 18 patients with Parkinson's disease(8 men, 10 women) with no history of neurological or psychiatric comorbidities. All these patients underwent identical brain blood oxygenation level-dependent functional magnetic resonance imaging for emotion evaluation. Blood oxygenation level-dependent functional magnetic resonance imaging results revealed that the occipito-temporal cortices, insula, orbitofrontal cortex, basal ganglia, and parietal cortex which are involved in emotion processing, were activated during the functional control. Additionally, positive emotions activate larger volumes of the same anatomical entities than neutral and negative emotions. Results also revealed that Parkinson's disease associated with emotional disorders are increasingly recognized as disabling as classic motor symptoms. These findings help clinical physicians to recognize the emotional dysfunction of patients with Parkinson's disease.

文摘Introduction: Diabetes mellitus type 2 is a growing threat in developing countries already burdened with high levels of infectious disease. Screening the general population has debatable advantages. This study aims to determine whether spouses of patients with diabetes mellitus have higher random blood glucose (RBG) levels as well as the benefit of RBG testing as a targetted screening tool. Methodology: The survey employed a cross-sectional comparative study of spouses’ of diabetics and non-diabetics attending the general out-patient department of the LagosStateUniversityTeaching Hospital (LASUTH), Ikeja. A modified WHO STEPS Surveillance Instrument and a one-touch Glucometer were used to collect data. Blood pressures and BMI were measured and correlated to blood glucose levels. Results: Prevalence of high RBG was found to be 7% among spouses of diabetics and 3.3% among spouses of non-diabetic patients. Mean RBG was 5.57 mmol/L and 7.7 mmol/L within the age group 40 - 49 years and 50 - 59 years respectively among spouses of diabetic patients compared to 5.4 mmol/L and 5.5 mmol/L within the same age group among the spouses non-diabetics. Spouses of patients with diabetes mellitus had higher systolic and diastolic blood pressures and BMI compared to spouses of non-diabetics. Conclusion: Being male, married to a diabetic patient, lower educational levels and higher body mass index are significantly associated with higher random blood glucose in the spouses of diabetic patients. Random blood glucose measurements are an effective screening tool and spouses of diabetic patients can benefit from targeted screening in controlled clinical settings.
文摘Background: Diabetes is a noncommunicable disease caused by high levels of blood glucose, and it is currently one of the most important public health problems in the world. It is important to know the prevalence of diabetes, the factors affecting blood glucose levels, and the percentage of people with diabetes taking medications. Data and Methods Data and Methods: We analyzed the distribution of blood glucose levels and prevalence of diabetes using 10,917,173 observations obtained from the JMDC Claims Database in Japan. The factors that may affect blood glucose levels were analyzed by a regression model using 5,472,205 observations. Treatment with diabetes medications was analyzed with 9,932,854 and 5,466,361 observations using a method to approximate the inverse of probability by a continuous piecewise linear function. Results: The prevalence of diabetes in 2019 was estimated to be 9.63% in males and 5.33% in females ages 20 - 79;10.78% and 7.04% for ages 20 - 89;and 10.93% and 7.65% for ages 20 - 99, respectively. In addition to age and gender, the important variables affecting blood glucose levels were <em>BMI</em>, <em>SBP</em>, <em>Triglyceride</em>, <em>ALT</em>, <em>AST</em> and <em>GGP</em>. The percentage taking medications increased up to a blood glucose level of around 175 mg/dL, but declined over that. Conclusion: The prevalence of diabetes in Japan was estimated using a very large dataset, and considering age, gender, and time trends. Some variables may be effective for controlling blood glucose levels. Nearly half of those at a serious stage of diabetes took no medications. Proper medical care for these individuals is necessary to prevent worsening diabetes and serious complications. Limitations: The dataset was observatory, and did not include those age 80 or over. Revising medical care systems to include those outside of hospitals is necessary;however, practical approaches have not yet been developed.
文摘Asphyxia could increase infant morbidity and mortality. Ante- and intrapartum cardiotocography (CTG) examination could lead to a false positive diagnosis of asphyxia (fetal distress). Troponin I (TnI) is an important factor to the pathogenesis of asphyxia. Cord blood TnI level is increased in infants with fetal cardiac dysfunction, causing pathological CTG and low APGAR score (<7). In the future, TnI is expected to reduce false positive diagnosis of asphyxia caused by CTG. This research was conducted to examine and analyze the differences of cord blood TnI level between normal and asphyxiated infants and to determine the correlation between TnI level and APGAR score. An observational analytical cross sectional study was conducted to a total of 36 patients with asphyxiated infants (18 patients) and normal infants (18 patients). Subjects were selected according to the inclusion and exclusion criteria. Cardiotocography, TnI level, and APGAR score were examined. Umbilical cord blood samples were taken from each subject for the measurement of TnIlevel using a highly sensitive indirect sandwich Enzyme Linked Immunosorbent Assay (ELISA). Statistical analysis was performed by Mann-Whitney and Rank Spearman correlation coefficient test. Cord blood TnI level of asphyxia andnormal groups were 1615.77 ± 1199.98 pg/mL and 819.88 ± 145.82 pg/mLrespectively (p ≤ 0.05). Rank Spearman correlation coefficient between cord blood TnI level and 1’ and 5’ APGAR score was -0.523 (p = 0.026;p ≤ 0.05)and -0.502 respectively (p = 0.034;p ≤ 0.05). There was a statistically significant difference between cord blood TnI level of asphyxia and normal groups;cord blood TnI level of asphyxia group was higher than normal group. Furthermore, negative correlation was observed between cord blood TnI level and APGAR score.
文摘One of the primary problems in the United States is diabetes. Cortex Lycii is an herb from Asia mostly used in traditional Chinese medicine. Although its main purpose is not for lowering blood glucose levels, there are studies on Cortex Lycii with other substances which have proven it can lower glucose level in type 2 diabetes rat. Unlike other experiments, this experiment only used Cortex Lycii as a single unit to see if there was any effect on blood glucose level. Also an observation was done on if Cortex Lycii could reduce blood glucose level after ingesting a high glucose diet. Rattus norvegicus was used in this project and in order for the subject to consume Cortex Lycii, the herb was boiled and the liquid was given for consumption. In order to increase the rats’ glucose levels, corn syrup and white sugar were added to the mixture. The data showed significant decrease of blood glucose when Cortex Lycii liquid was ingested. This research has shown that Cortex Lycii can be a potential treatment for hyperglycemia or diabetes. With further research, there can be an alternative treatment rather than injecting external hormones (Insulin).

文摘In recent decades, due to the increasing risk of diabetes, the measurement and control of the blood sugar is of great importance. In typeI diabetes, because of the lack of insulin secretion, the cells cannot absorb glucose, and thus have a low level of glucose. To control blood glucose, the insulin must be injected to the body. In fact, the injection must be in a completely controlled environment. If the level of the insulin exceeds the physiological limits, it may cause death. This paper presents an online approach to control the blood glucose level using a nonlinear model predictive control. This method, maintains the level of blood glucose concentration within a normal range. Thus, the blood glucose level is measured in each minute and predicted for the next time interval. If that is not in the normal range, amount of the insulin which must be injected will be determined. The proposed control approach includes important features such as model uncertainties and prevents acute decrease in the blood glucose level, and instability. In order to assess performance of the proposed controller, computer simulations have been carried out in Matlab/Simulink. Simulation results will reveal the effectiveness of the proposed nonlinear model predictive controller in adjusting the blood glucose level by injecting required insulin. So if the nutrition of the person decreases instantly, the hypoglycemia does not happen.
