The objective of this study was to perform a systematic review of the literature for application of intranasal sodium citrate in the patients with olfactory dysfunction to help determine the sodium citrate treatments for this condition. Two authors independently searched the data base (Medline, Scopus, and the Cochrane database) for relevant studies from inception to January 2018. Included studies were randomized controlled studies published in English comparing topical sodium citrate application (treatment group) with saline (control group) in patients who had olfactory dysfunction. Outcomes of interest included the change of olfactory identification and threshold during 2 hours post-treatment. Three studies were enrolled in the meta-analysis. Compared with control group, treatment group did not increase posttreatment score of olfactory identification [standardized mean difference (SMD)=-0.03; 95% confidence interval (CI)=-0.29-0.24; I²=0%] and olfactory threshold (SMD=0.18; 95% CI=-0.09-0.45; I²=0%) significantly. In the degree of pre-post improvement of two outcomes, although treatment group statistically showed the significant improvement in olfactory threshold (SMD=0.30; 95% CI=0.05-0.55; I²=17%), the clinical significance of this outcome was meaningless. Similarly, there was no significant difference in olfactory identification between two groups (SMD=0.17; 95% CI=-0.11-0.45; I²=22%). Unlike the recent favorable results, our summated results presented the uselessness for the local application of sodium citrate in improving patient's olfactory function. However, we also had some limitation such as small sample size and inconsistent application methods. Therefore, larger trials and standardized methodology are needed to reach more stronger and exact results.

Purpose : This study aimed to investigate the characteristics and risk factors associated with pressure injuries related to medical devices among patients admitted to the intensive care unit (ICU). Method : A retrospective study analyzed data from 462 ICU patients. Statistical analyses, including independent t-tests, Fisher's exact tests, and logistic regression were performed to analyze the data. Results : Among the 154 subjects, there were a total of 198 medical device-related pressure injuries (MDRPI). Stage 2 and deep tissue pressure injuries were the most frequent. MDRPI occurred most frequently on the face, with nasogastric tubes being its leading cause, followed by endotracheal tubes. The risk factors for MDRPI included male sex (odds ratio [OR]=1.78, 95% confidence interval [CI]=1.12-2.83), department at the time of ICU admission (OR=4.29, 95% CI=2.01-9.15), post-surgery ICU admission (OR=0.43, 95% CI=0.25-0.73), application of extracorporeal membrane oxygenation machines (OR=2.72, 95% CI=1.06-6.95), number of medical devices (OR=1.16, 95% CI=1.05-1.30), inotropic drug administration (OR=2.33, 95% CI=1.19-4.60), and sedative use (OR=2.53, 95% CI=1.17-5.45). Conclusion : These results enable the determination of the characteristics and risk factors associated with MDRPI. It is crucial to acknowledge the risk factors for MDRPI in ICU patients and establish a prevention strategy.

Background: Surgical excision is the treatment of choice for feline intracranial meningioma. Objectives: To report clinical findings, complications, and outcomes following surgery for feline intracranial meningioma. Methods: Medical records (01/2000-01/2017) of cats that underwent surgical excision of an intracranial meningioma at our institution were reviewed. Patient data included signalment, clinical signs, surgical technique, complications, histopathologic diagnosis, survival time, and owners' answers to a satisfaction questionnaire. Survival was assessed using the Kaplan-Meier method and log-rank test. Results: Twenty-six cats were included in this study. The exact cause of death was known in 17 cases and was not related to meningioma in 9/17 cases. Overall median survival time was 881 days (95% confidence interval 518; 1248). The age of the cat did not influence survival (p = 0.94) or the occurrence of complications (p = 0.051). Complications occurred in 13/24 cats, including dramatic complications in 4/24 cats. Most complications appeared in the first 24 hours post-surgery (12/13). Males had more postoperative complications (p = 0.042), including more seizures (p = 0.016). Cats with cranioplasty had fewer complications (p = 0.021). Clinical recurrence was confirmed in 3 out of 17 cats. Recurrence-free survival time was 826 days. Most owners (12/14) were satisfied with the outcome. Conclusions: Surgical treatment of intracranial meningioma in cats was associated with a long median survival time but also with a high rate of minor and major postoperative complications, including early postoperative seizures. Cranioplasty may reduce complications. Age at the time of surgery had no effect on outcomes.

연구배경: 와파린의 치료 효과를 유지하고 부작용을 방지하기 위해서는 수시로 프로트롬빈 시간을 모니터링 할 필요가 있다. 이러한 목적의 현장검사기기는 편리하지만 그 정확성에 있어서 문제가 될 수 있으므로 평가가 필요하다. 방 법: 2007년 8월부터 2008년 2월까지 순천향대학교 부천병원에 내원한 환자 중에서 경구용 항응고제(와파린)를 복용하는 85명의 환자들을 대상으로 하여 검사실 표준검사법과 CoaguChek-XS를 사용하여 각각 INR값을 측정하고 비교 분석하였다. 결 과: 전체 85명 환자 중 2번 이상 INR을 측정한 사람 은 모두 25명으로 이들의 INR 측정간격은 평균 8.6주이었고, CoaguChek-XS와 표준검사법에서 INR 2.0 미만의 측정값들이 각각 39%, 38%를 차지하였다. 와파린을 복용하는 환자에서 표준검사법으로 측정한 INR값이 높고, 낮은 두 명의 환자에서 각각 5번씩 측정한 결과 CoaguChek-XS의 변이계수는 각각 4.50, 2.45, CA-7000은 각각 1.67, 0.66이었다. 두 검사 기기간의 상관성은 $R^2$이 0.966으로서 우수하였으며 Bland-Altman 분석을 통해서 두 기기간 차이의 평균이 0.13이었고 일치범위의 한계(95% 신뢰구간)는 -0.47~+0.72이었다. 또한 INR 값이 증가할수록 CoaguChek-XS의 측정값은 표준방법에 비해서 높게 측정되는 경향을 보였다. 결 론: CoaguChek-XS는 정밀도가 좋고 기존의 검사실표준검사법과의 상관성이 우수하였다. 따라서 CoguChek-XS는 경구 항응고제 치료환자의 INR을 모니터링 하는데 도움이 될 것으로 생각된다.

Objectives: Studies on the geographical differences in mortality tend to use a census population, rather than a registration population, as the denominator of mortality rates in South Korea. However, an administratively determined registration population would be the logical denominator, as the geographical areas for death certificates (numerator) have been determined by the administratively registered residence of the deceased, rather than the actual residence at the time of death. The purpose of this study was to examine the differences in the total number of a district population, and the associated district-specific mortality indicators, when two different measures as a population denominator (census and registration) were used. Methods: Population denominators were obtained from census and registration population data, and the numbers of deaths (numerators) were calculated from raw death certificate data. Sex- and 5-year age-specific numbers for the populations and deaths were used to compute sex- and age-standardized mortality rates (by direct standardization methods) and standardized mortality ratios (by indirect standardization methods). Bland-Altman tests were used to compare district populations and district-specific mortality indicators according to the two different population denominators. Results : In 1995, 9 of 232 (3.9%) districts were not included in the 95% confidence interval (CI) of the population differences. A total of 8 (3.4%) among 234 districts had large differences between their census and registration populations in 2000, which exceeded the 95% CI of the population differences. Most districts (13 of 17) exceeding the 95% CI were rural. The results of the sex- and age-standardized mortality rates showed 15 (6.5%) and 16 (6.8%) districts in 1995 and 2000, respectively, were not included in the 95% CI of the differences in their rates. In addition, the differences in the standardized mortality ratios using the two different population denominators were significantly greater among 14 districts in 1995 and 11 districts in 2002 than the 95% CI. Geographical variations in the mortality indicators, using a registration population, were greater than when using a census population. Conclusion: The use of census population denominators may provide biased geographical mortality indicators. The geographical mortality rates when using registration population denominators are logical, but do not necessarily represent the exact mortality rate of a certain district. The removal of districts with large differences between their census and registration populations or associated mortality indicators should be considered to monitor geographical mortality rates in South Korea.

The objective was to evaluate the use of prediction equations based on the chemical composition of feedstuffs to estimate the values of apparent metabolisable energy corrected for nitrogen balance (AMEn) of corn and soybean meal for broilers. For performance and carcass characteristics, 1,200 one-d-old birds (male and female) were allotted to a completely randomised factorial $2{\times}8$ (two genders and eight experimental diets) with three replicates of each sex with 25 birds. In the metabolism trial, 240 eight-d-old birds were distributed in the same design, but with a split plot in time (age of evaluation) with five, four and three birds per plot, respectively, in stages 8 to 21, 22 to 35, and 36 to 42 d of age. The treatments consisted of the use of six equations systems to predict the AMEn content of feedstuffs, tables of food composition and AMEn values obtained by in vivo assay, totalling eight treatments. Means were compared by Scott-Knott test at 5% probability and a confidence interval of 95% was used to check the fit of the energy values of the diets to the requirements of the birds. As a result of this study, the use of prediction equations resulted in better adjustment to the broiler requirements, resulting in better performance and carcass characteristics compared to the use of tables, however, the use of energy values of feedstuffs obtained by in vivo assay is still the most effective. The best equations were: AMEn = 4,021.8-227.55 Ash (for corn) combined with AMEn = -822.33+69.54 CP-45.26 ADF+90.81 EE (for soybean meal); AMEn = 36.21 CP+85.44 EE+37.26 NFE (nitrogen-free extract) (for corn) combined with AMEn = 37.5 CP+46.39 EE+14.9 NFE (for soybean); and AMEn = 4,164.187+51.006 EE-197.663 Ash-35.689 CF-20.593 NDF (for corn and soybean meal).

Objectives: The existing reductionist approach has not reached complete understanding of the cause of schizophrenia. The objective of this study was to investigate yin-yang and five-element characteristics reflected on four time pillars of birth of patients with schizophrenia through comparison with the general population in the perspective of consilience-based holistic approach. Methods: This study was conducted using a random sequential recruitment method for the general population and individuals with schizophrenia aged 18 to 64 based on the exact date and time of birth using structured questionnaires. Relative positional relations of yin-yang and five-element with day master were primarily examined. In addition, the strength of day master with a score range of 0~100 points was assessed through operational score allocation. Results: Of 591 participants, 576 (346: general population, 230: individuals with schizophrenia) were analyzed. Between-group analyses showed no significant difference in the distribution of types of day master (χ²=10.41, df=9, p=0.318). However, significant between-group differences were shown in the distribution of the strength of day master (t=2.14, p=0.032) and frequency of restraining month branch (χ²=5.23, df=1, p=0.022). In logistic regression analysis, 10-point increase on the strength of day master decreased the probability of onset of schizophrenia over the age of 30 by 29.6% (p=0.002; 95% confidence interval, 0.566~0.876). Conclusions: Findings in this study suggest that four time pillars of birth might be associated with schizophrenia through yin-yang and five-element theory and synchronicity principle, implicating the plausibility of consilience-based holistic approach in the determination of risk factors or cause of schizophrenia.

$^{18}F$-FDG PET 검사는 포도당 대사를 이용하여 전신의 종양을 평가하는 검사로 전처치 과정에서 혈당 측정의 중요성이 매우 높다. 혈당 수치가 높은 상태에서 FDG를 투여하면 FDG와 혈중 포도당이 세포 내 흡수에 서로 경쟁하게 되고 종양으로의 FDG 섭취가 감소되어 정확한 검사가 되지 않을 가능성이 있다. 혈당 측정에 사용되는 혈당 측정 검사지는 경우에 따라 모세혈관혈 전용 측정 검사지와 모세혈관혈과 정맥혈을 모두 측정 가능한 범용 측정 검사지로 구분되어 있는데, 정확한 혈당 측정 검사지(스트립)의 사용에 따른 혈당 수치의 차이를 비교 분석 하였다. 연구 대상은 2010년 3월부터 4월까지 서울아산병원 핵의학과에서 $^{18}F$-FDG whole body PET 검사를 시행한 환자 중 46명(남자: 32명, 여자: 14명, 평균연령 $57.3{\pm}12.3$세) 을 연구의 대상으로 하였다. 실험기기는 Abbott사의 Optium Xceed혈당 측정기를 이용하였고, 모세혈관혈과 정맥혈을 모두 측정 가능한 범용 측정 검사지를 사용하여 동일 환자의 모세혈관혈과 정맥혈의 혈당 수치의 차이를 분석하였다. 또한, 모세혈관혈 전용 측정 검사지를 사용하여 동일 환자의 모세혈관혈과 정맥혈의 혈당 수치의 차이를 비교 분석하였다. 분석방법은 MINITAB 통계 프로그램을 이용하여 paired t-test 검정을 시행하였다. 모세혈관혈과 정맥혈을 모두 측정 가능한 범용 측정 검사지로 측정한 동일 환자의 모세혈관혈과 정맥혈의 혈당 수치는 각각$95.2{\pm}12.4$ mg/dL, $104.1{\pm}14.4$ mg/dL (t=8.0, p<0.001)로 통계적으로 유의한 차이가 있었다. 모세혈관혈 전용 측정 검사지로 측정한 동일 환자의 모세혈관혈과 정맥혈의 혈당 수치는 각각 $91.5{\pm}13.6$ mg/dL, $108.1{\pm}16.2$ mg/dL (t=9.2, p<0.001)로 통계적으로 유의한 차이가 있었다. 선행연구에 의하면 모세혈관혈과 정맥혈의 혈당 수치는 여러 가지 이유로 인해 차이가 있는 것으로 보고 되었고 본 연구의 결과도 유사한 차이를 확인하였다. $^{18}F$-FDG PET 검사 전에 혈당 수치를 측정할 때 모세혈관혈 전용 측정 검사지로 정맥혈의 혈당을 측정하는 것은 부정확한 혈당 수치를 측정할 수 있으므로 주의해야 할 것이다. 그러므로 적합한 측정 검사지와 규정된 측정절차를 이행하는 것이 측정 편차를 줄일 수 있어 PET 검사의 전처치를 보다 명확하게 확인할 수 있을 것이다. 또한, 혈당 측정 시에 혈액 채취 부위를 모세혈관 또는 정맥혈관 중에서 항상 동일한 부위에서 측정하는 등의 표준화 과정이 필요할 것이다.
