Serum lipids and lipoproteins were determined in 70 patients with hypertension, 40 patients with cerebral infarctions, and 41 patients with cerebral hemorrhage. The results were compared with findings in 64 healthy controls. The results are as follows; 1) Total cholesterol, VLDL-cholesterol, LDL cholesterol and total cholesterol/HDL-cholesterol ratio were significantly higher in patients with hypertension or cerebral infarction than in control group, but HDL-cholesterol showed no significant difference. 2) In Patients with cerebral hemorrhage, total cholesterol, LDL-cholesterol and HDL-cholesterol were higher than in normal controls. Total cholesterol/HDL-cholesterol ratio was within the limits of normal. It is possible that the susceptibility to cerebral infarction is the result of high total cholesterol/HDL cholesterol ratio rather than low HDL cholesterol. But our study suggests that hyperlipoproteinemia plays a minor role in the development of cerebral hemorrhage.

BACKGROUND: Modified ultrafiltration (MUF) has been demonstrated to have beneficial effects in children undergoing cardiac surgery with cardiopulmonary bypass (CPB). In adults, the hemodynamic effects of MUF are little known. The purpose of this investigation is to evaluate the hemodynamic effects of MUF in adult patients undergoing valvular heart surgery. METHODS: 30 patients scheduled for elective mitral valvular surgery were randomized into either Ultrafiltration (U) or Control (C) group. In the U group, MUF was performed just after termination of CPB for 20 minutes, and not in the C group. Measurements of hemodynamic variables including right ventricular ejection fraction (RVEF) measured by thermodilution technique and hematocrit were performed before induction, just after termination of CPB, after completion of MUF and after sternal closure. Measurement after MUF in the C group was performed at 20 minutes after the termination of CPB. After transfer to ICU, same measurements were performed at postoperative 6 and 12 hrs. RESULTS: After MUF, RVEF (P < 0.05) and hematocrit (P < 0.01) increased in the U group, compared to the corresponding values measured just after termination of CPB. However, the variables were not statistically different between the two groups throughout the intraoperative procedures and during ICU stay. CONCLUSIONS: Conclusively, MUF was demonstrated to have the transient beneficial effect of improving the right heart function and hemoconcentration immediately after termination of CPB.

BACKGROUND: IS6110 DNA fingerprint is a very useful tool for investigating the transmission of tuberculosis. The aim of this study was to identify the epidemiological situations within a given area (one province). METHODS: The 681 Mycbobacterium tuberculosis isolates from patients, who were registered at health centers in Gyeonggi Province from May to December in 2004, were subjected to IS6110 DNA fingerprinting. Patients belonging to clusters were interviewed by health-workers to determine their previous contacts or household TB history. RESULTS: The number of IS6110 copies of the 681 isolates showed diverse fingerprint patterns from 0 to 21 of which the most prevalent copy number was 10 from 120 isolates (17.6%). Thirty-three isolates (4.8%) belonged to the K strain, and 128 isolates (18.8%) belonged to the K family. There were 180 (26.4%) isolates belonged belonging to fifty clusters, of which two clusters were within household transmission. Forty-three (23.9%) out of 180 patients resided in an area under the same health center control. The rate of clusters in those aged 60-70 was higher than in any other age group ( 95% CI of RR : 1.072 ~ 1.988). CONCLUSION: This is the first report of an epidemiological survey based on a whole province using a DNA fingerprinting technique for M. tuberculosis. These results will be helpful in developing a program or policies to prevent the transmission of TB.

PURPOSE: To estimate annual health care and productivity loss costs attributable to overweight or obesity in working asthmatic patients. MATERIALS AND METHODS: This study was conducted using the 2003–2013 Medical Expenditure Panel Survey (MEPS) in the United States. Patients aged 18 to 64 years with asthma were identified via self-reported diagnosis, a Clinical Classification Code of 128, or a ICD-9-CM code of 493.xx. All-cause health care costs were estimated using a generalized linear model with a log function and a gamma distribution. Productivity loss costs were estimated in relation to hourly wages and missed work days, and a two-part model was used to adjust for patients with zero costs. To estimate the costs attributable to overweight or obesity in asthma patients, costs were estimated by the recycled prediction method. RESULTS: Among 11670 working patients with a diagnosis of asthma, 4428 (35.2%) were obese and 3761 (33.0%) were overweight. The health care costs attributable to obesity and overweight in working asthma patients were estimated to be $878 [95% confidence interval (CI): $861–$895] and $257 (95% CI: $251–$262) per person per year, respectively, from 2003 to 2013. The productivity loss costs attributable to obesity and overweight among working asthma patients were $256 (95% CI: $253–$260) and $26 (95% CI: $26–$27) per person per year, respectively. CONCLUSION: Health care and productivity loss costs attributable to overweight and obesity in asthma patients are substantial. This study's results highlight the importance of effective public health and educational initiatives targeted at reducing overweight and obesity among patients with asthma, which may help lower the economic burden of asthma.

It is well known that tumor necrosis factor (TNF-a), interleukin-1, platelet-activating factor (PAF) and arachidonic acid metabolites, such as thromboxane and leukotriens, are major mediators involved in the pathogenesis of endotoxic shock. In this study, we have investigated the effect of pentoxifylline (inhibitor of TNF-a release), BN50739 (PAF antagonist), indomethacin (cyclooxygenase inhibitor) and diethylcarbamazine (lipoxygenase inhibitor) on LPS- induced lethality as well as the relationship between major mediators in endotoxic shock. All inhibitors described above except diethylcarbamazine significantly protected mice against LPS- induced lethality. BN50739 and indomethacin were also effective in protection of TNF-a-induced lethality. The elevation of circulating TNF-a by LPS was significantly blocked by BN50739, but not affected by indomethacin. Convulsion appeared shortly after LPS injection was prevented by BN50739 but not by indomethacin, whereas diarrhea and limited movement was prevented by indomethacin but not by BN50739. These results indicate that i) TNF-a, PAF and cyclooxygenase products are important mediators involved in the pathogenesis of septic shock and ii) TNF-a directly influenced the release or production of PAF as well as cyclooxygenase products, and strongly suggest that i) TNF-a and PAF stimulate the release of each other via positive feedback network but TNF-a and cyclooxygenase products do not form the network and ii) PAF and cyclooxygenase product appear not to affect the release of each other.

OBJECTIVE: To identify 1) whether the endogenous steroid hormone metabolism in patients with pelvic organ prolapse was different from that of normal women, 2) the relationship between endogenous steroid hormone metabolites and the stage of the pelvic organ prolapse. METHODS: Twenty postmenopausal women who were clinically diagnosed as having pelvic organ prolapse and 20 volunteer postmenopausal women not having pelvic organ prolapse were included in the study. We compared the urinary profiles of endogenous steroids between the two groups and investigated the relationship between urinary profiles of the endogenous steroids and the degree of pelvic organ prolapse. Urinary profiles of the endogenous steroids were assayed by gas chromatography-mass spectrometry. RESULTS: The ages of the patients and control group were 64.6 +/- 6.5 and 63.5 +/- 3.9 years, and the Body Mass Index (BMI) was 23.96 +/- 3.14 and 24.11 +/- 2.73 kg/m2 in patients and in normal subjects, respectively. The number of patients in each stage were 4 in stage I, 4 in stage II, 6 in stage III and 6 in stage IV. 5-androstene-3beta, 16beta, 17beta-triol (5-AT), 11beta-hydroxy androstenedione (An) and 17beta-estradiol were significantly increased in patients with pelvic organ prolapse over that of the control group (0.76 +/- 0.67 vs 0.06 +/- 0.03 micro mole/g creatinine; p=0.002, 1.16 +/- 0.83 vs 0.65 +/- 0.23 micro mole/g creatinine; p=0.04, 15.08 +/- 9.81 vs 8.53 +/- 6.19 micro mole/g creatinine; p=0.04). However, tetrahydrocortisone (THE) was significantly increased in the control group over that in patients having pelvic organ prolapse (9.80 +/- 6.21 vs 5.22 +/- 4.89 micro mole/g creatinine; p=0.04). The androgen metabolites, 5-AT and THE significantly correlated with the POP-Q stage (R=0.418; p=0.027, R=0.46; p=0.016). Among the estrogen metabolites, 17beta-estradiol was correlated to the POP-Q stage but not mathematically significantly (R=0.38; p=0.05) and the 17beta-estradiol/estrone ratio weakly correlated to pelvic organ prolapse stage (R=0.14; p=0.49), by showing a low correlation coefficiency. CONCLUSION: The urinary concentrations of 17beta-estradiol, 5-AT and 11beta-hydroxy An increased in patients with pelvic organ prolapse over that of the control group and 5-AT, THE and 17beta-estradiol showed a relationship to the progression of pelvic organ prolapse in Korean women. The metabolites of endogenous steroid hormones could be contributing factors in the pathogenesis of pelvic organ prolapse.
