Purpose: Diabetic ketoacidosis (DKA) is a fatal complication caused by unregulated diabetes. Lactate is used as a prognostic indicator for a range of serious illnesses and its level is higher in DKA patients. This study examined the utility of lactate and lactate clearance measurements at an emergency department for predicting the prognosis of DKA patients. Methods: This was a retrospective, observational study of patients with DKA presenting to the emergency department of an urban and rural tertiary hospital between January, 2013 and December, 2016. The demographic and laboratory data were collected through a chart review. Results: Seventy-six patients with DKA were included. Of these 76 patients, 46 (56.8%) had lactic acidosis (lactate >2.5 mmol/L) and 24 (29.6%) had a high lactate level (>4 mmol/L). Lactate and lactate clearance showed a significant difference in terms of the intensive care unit length of stay and mortality. Conclusion: Lactate and lactate clearance measurements in DKA patients are favorable and significant prognostic factors. In DKA patients, serial measurements of lactate should be considered.

최근 고용 없는 성장으로 실업률이 높아지면서 정부는 창업활성화를 위해 많은 정책을 추진하고 있으며 그 중 기술을 기반으로 한 입주기업에게 물리적, 비물리적 서비스를 제공하고 있는 창업보육사업이 다시 주목 받고 있다. 창업보육센터는 2018년 현재 262개가 운영되고 있으며 6,000여개의 기업이 입주하고 있다. 이에 본 연구는 선행연구를 통해 입주기업 기업성과에 영향 을 미치는 요인들을 살펴보고 한국창업보육협회의 데이터 및 문헌 연구를 통해 창업보육센터 입주기업 특성과 정부지원정책이 기업성과에 미치는 영향을 실증적으로 분석하고자 한다.

Purpose: Although minimally invasive follicular thyroid carcinoma (MIFTC) is considered a thyroid tumor with low malignant potential, some MIFTC can spread, metastasize, and eventually lead to death. This study investigates the risk factors for distant metastasis in MIFTC patients. Methods: Between 1981 and 2014, the records of 365 consecutive patients who underwent thyroidectomy for MIFTC at Seoul National University Hospital were reviewed. Univariate and multivariate analyses were performed to identify risk factors associated with distant metastasis. Results: Of 351 patients, 10 (2.9%) presented with distant metastasis. Of these, two (0.6%) were found at the time of thyroidectomy, while eight (2.3%) were detected at later exams, over a median of 7.3 years (range, 0.2∼30.8). In univariate analysis, lymph node metastasis (P<0.001) was significantly associated with distant metastasis. In multivariate analysis, lymph node metastasis (P<0.001) and locoregional recurrence (P=0.008) were significantly associated with distant metastasis. Conclusion: Distant metastasis in MIFTC patients were associated with high-risk clinicopathologic features and more aggressive clinical courses. Further study will be needed to ascertain these results with long-term surveillance.

대인면접조사와 비교한 온라인 서베이조사 참여자들의 인구통계적 특성과 제품구매행태에 대한 연구-20대~40대 소비자를 중심으로-

The usage of online survey in marketing research is expanding with the increase of internet use among domestic and global consumers. Still, the difference in results of online consumer survey compared to the traditional face-to-face (FTF) survey has not been fully investigated in domestic market. The difference may occur due to diverse reasons, like the exclusion of internet nonusers, sampling process, and the bias from selective participation. The purpose of this study is to find out any difference between results of online and offline survey for a segment of 20 to 40 years old, whose internet usage rate is very high. Especially, the difference in the area of diverse demographic characteristics, media usage, product buying pattern will be studied. For this, two surveys with the identical questionnaire are performed in the Seoul and other major cities. The first is an online survey applied to a consumer panel set up by an online research firm based on the population of domestic internet users. The second is a face-to-face survey applied to general consumers. For both surveys, quota sampling method is used with the sampling criteria of area, sex, and age. The sample size is 1,000 respondents respectively. The results from online survey is found to be a little different from those of offline survey. Firstly,in demographic characteristics, participants of online survey are found to have relatively high income and high education. In occupation, the ratio of white color is shown to be higher compared to face-to-face survey. For the offline survey, the portion of white color is relatively lower and that of homemakers, salespersons, and self-employed persons is found to be higher as they are easier to approach in the street than the white color. Secondly, online participants are found to spend more time than general consumers in diverse media like the internet, TV, newspapers, and magazines. The abundant information gathered from the diverse media has a direct impact on the lifestyle and product buying pattern of online survey participants. Overall, online survey participants have more interest in fashion and enjoy good food. In product buying, they show a tendency of early adopters for many products in growing markets. 국내 소비자들의 인터넷 사용 증가에 따라 마케팅 분야에서 온라인조사의 비중이 점차 확대되고있다. 그럼에도 불구하고 인터넷 비이용자의 처리나 표본추출과정에서 조사 참여자들과 비참여자들의 차이등에 의해 야기되는 온라인조사 결과의 특성에 대한 연구는 충분히 이루어지지 않은 상태이다. 이에 본 연구에서는 마케팅조사의 주 대상이며 인터넷 사용비율이 높은 20~40대를 대상으로 온라인조사 참여자의 다양한 인구통계적 구성과 제품구매, 라이프스타일과 같은 특성이 일반인을 모집단으로 하는 대인면접 서베이조사와 비교할 때 어떤 차이가 있는 지를 검토하였다. 이를 위해 인터넷 사용자를 모집단으로 구축된 조사패널을 대상으로 온라인조사를 실시하고 일반 소비자를 대상으로 동일한 내용의 대인면접조사를 실시하여결과를 비교하였다. 그 결과, 온라인조사 참여자들은 오프라인조사의 응답자들에 비해 전반적으로 소득과 학력이 높은 집단으로 나타났으며, 직업에서도 사무․전문 관리직의 비중이 높은 것으로 나타났다. 반면 오프라인조사로 접근하기 어려운 무직이나 저소득층에 대한 접근도 온라인조사를 통해 가능한 것으로 나타났다. 온라인조사 참여자들의 인구통계적 차이는 라이프스타일과 제품구매행태에도 영향을 미쳐 온라인조사 참여자들은 인터넷을 포함한 다양한 매체를 이용하고 정보를 접하면서 제품 구매에 있어 조기수용층(early adopter)의 특성을 보이는 것으로 나타났다

Association between Number of Retrieved Sentinel Lymph Nodes and Breast Cancer-related Lymphedema

김홍규,주영욱,이준우,김경은,정지광,김유미,이한별,문형곤,노동영,서관식,한원식 한국유방암학회 2021 Journal of breast cancer Vol.24 No.1

Purpose: Sentinel lymph node biopsy (SLNB) has become a standard axillary staging surgery for early breast cancer, and the proportion of patients requiring axillary lymph node dissection (ALND) is decreasing. We aimed to evaluate the association between the number of sentinel lymph nodes (SLNs) retrieved and the risk of lymphedema of the ipsilateral arm. Methods: Prospectively collected medical records of 910 patients were reviewed. Lymphedema was defined as a difference in circumference > 2 cm compared to the contralateral arm and/or having clinical records of lymphedema treatment in the rehabilitation clinic. Results: Together with an objective and subjective assessment of lymphedema, 36 patients (6.1%) had lymphedema in the SLNB group and 85 patients (27.0%) had lymphedema in the ALND group (p < 0.001). In a multivariate analysis of the whole cohort, risk factors significantly associated risk with the development of lymphedema were body mass index, mastectomy (vs. breast-conserving surgery), ALND, and radiation therapy. In logistic regression models in the SLNB group only, there was no correlation between the number of retrieved SLNs and the incidence of lymphedema. In addition, in the Pearson correlation analysis, no correlation was observed between the number of retrieved SLNs and the difference in circumference between the ipsilateral and contralateral upper extremities (correlation coefficients = 0.067, p = 0.111). Conclusion: The risk of lymphedema in breast cancer surgery and adjuvant treatments is multifactorial. The number of retrieved lymph nodes during sentinel biopsy was not associated with the incidence of lymphedema.
