BACKGROUND: It is difficult to evaluate the effectiveness of ongoing cardiopulmonary resuscitation(CPR). Recent studies suggest that continuous end-tidal carbon dioxide(ETC02) monitoring may be useful non-invasive indicator of CPR. The purpose of this study is to determine whether ETC02 monitoring during CPR could be used as a prognostic indicator of resuscitation and survival. METHOD: A prospective, clinical study was performed from May 1997 to April 1998 at the department of emergency medicine, Ewha Womans University Mokdong hospital. All patients were immediately connected to mainstream capnometer sensor between the tube and the bag after endotracheal intubation using infrared capnometer. RESULT: The study included 70 patients (39 were men) with a mean age of 55+/-16 years. 37 patients with return of spontaneous circulation(ROSC) had higher maximal ETCO2 during CPR than 33 Patients without ROSC (26.9+/-19.4 vs 10.2+/- 9.0mmHg, p=0.0001). The ETCO2 was not significantly different in relation to age, gender, initial rhythm, and survival time after ROSC. But there was significant difference in immediate cause of arrest in ROSC group (P=0.0016). When maximal ETC02 was less than 10mmHg, we observed sensitivity of 83.8%, specificity of 54.5% in predicting ROSC. There were 6 patients with ROSC in spite of maximal ETCO2 was less than 10mmHg. CONCLUSION: Continuous ETCOB monitoring during CPR may be useful, noninvasive, and valuable predictor of successful resuscitation and survival from cardiac arrest. But ETCO2 should lot be used as a single indicator for the withdrawal of CPR.

PURPOSE: This study aimed to examine the effects of subjective memory complaints, depression and cognitive function on performance of activities of daily living (ADL) in individuals with mild cognitive impairment (MCI). METHODS: A total sample consisted of 250 MCI patients diagnosed within one year. All participants were assessed with a battery of standardized neuropsychological tests, self-report measures of subjective memory complaints and depression, and performance of basic and instrumental ADL. Correlational and multiple linear regression analyses were conducted to identify the factors associated with performance of basic and instrumental ADL, respectively. RESULTS: Executive function and depression explained 9.4% of the variance in basic ADL. Reduced executive function and greater depressed mood were associated with worse performance on basic ADL. Executive function, subjective memory complaints, and time since onset of cognitive symptoms accounted for 22.2% of the variance in instrumental ADL in individuals with MCI. Lower executive function (t=−2.02, p=.044), greater memory complaints (t=5.36, p<.001), and longer periods of experiencing cognitive symptoms (t=2.24, p=.026) were associated with worse instrumental ADL performance. CONCLUSION: These results may help healthcare professionals develop interventions to improve cognitive outcomes with better understanding of the relationship among cognition, mood, and behavioral performance in individuals with MCI.

BACKGROUND: To identify the prevalence and related factors for vitamin D deficiency in the patients who admitted to the medical intensive care unit (ICU) of a Korean tertiary care hospital. METHODS: We retrospectively analyzed the data from ICU patients requiring mechanical ventilation (MV) for a period of > 48 h to identify the prevalence and associated factors for vitamin D deficiency. Vitamin D deficiency was defined as serum 25-hydroxyvitamin D [25(OH)D] level < 20 ng/mL. RESULTS: Among 570 patients admitted to the ICU, 221 were enrolled in the study, 194 in the vitamin D deficient group and 27 in the non-deficient group. Prevalence of vitamin D deficiency in critically ill patients was 87.8%. The patient age was lower in the vitamin D deficient group compared with the non-deficient group (64.4 ± 15.4 vs. 71.0 ± 9.6 years, p = 0.049). A higher acute physiology and chronic health evaluation II (APACHE II) score (odds ratio [OR] 1.23, 95% confidence interval [CI] 1.10-1.37) and chronic illness (OR 3.12, 95% CI 1.08-9.01) were associated with vitamin D deficiency after adjusting for age and body mass index. Clinical outcomes of duration of MV, ICU stay, and 28- and 90-day mortality rates were not significantly different between the vitamin D deficient and nondeficient groups. CONCLUSIONS: Vitamin D deficiency was common in critically ill patients, particularly among younger patients. Higher APACHE II score and chronic illness were associated with vitamin D deficiency.

OBJECTIVES: The diagnosis of ASCUS(atypical squamous cells of undetermined significance) and LSIL(low-grade squamous intraepithelial lesion) was introduced in 1988 by the Bethesda system for reporting cervical/vaginal cytologies. A significant proportion of women referred for colposcopy with low grade cervical cytologic abnormalities(ASCUS and LSIL) will have high grade cervical intraepithelial neoplasia(CIN II or CIN III) and therefore require adequate management. The purposes of this study were to evaluate the usefulness of high risk type HPV(human papillomavirus) DNA detection using PCR(polyerase chain reaction) in patients with low grade cervical cytologic abnormalities in the prediction of high grade CIN and invasive cancer and to determine the clinical triage in the management of low grade cervical cytologic abnormalities. METHODS: We reviewed 18,942 cases of Papanicolau smears that were performed at our hospital from Jan. 1995 to Mar. 1999. Colposcopically directed biopsy or LLETZ(large loop excision of transformation zone) or hysterectomy were performed on 318 patients with abnormal PAP smears of low degree. HPV PCR testing of high risk types(16 and 18) was also performed on 115 patients. RESULTS: Histologic outcome of ASCUS included 43 cases(38.4%) of high grade CIN and invasive cancer, and that of LSIL included 65 cases(47.5%) of high grade CIN and invasive cancer. In cases of high risk HPV type, 19 patients(73.1%) were at age over 30 years. A highly significant correlation was found between a positive test for high risk types of HPV and finding of high grade CIN and invasive cancer. Among 51 women with ASCUS, a positive test for high risk type had a sensitivity and specificity of 40.0% and 86.1%, and positive predictive value(PPV) and negative predictive value(NPV) of 54.5% and 77.5%, respectively. In 64 women with LSIL, a positive high risk type test was associated with sensitivity and specificity of 30.0% and 94.1%, and PPV and NPV of 81.8% and 60.4%, respectively. CONCLUSION: Our results suggest that high risk type HPV may be positively predictive of and may act as a surrogate marker for high grade CIN and invasive cancer in women with low grade cervical cytologic abnormalities. The management of women with a low grade cervical cytologic abnormalities should be active such as colposcopically directed biopsies.
