Cognitive impairment is age-related and manageable only with early diagnosis and prevention. Moxibustion is widely accepted in East Asia as useful for preventing cognitive impairment. This systematic review of animal studies was conducted to verify the efficacy of moxibustion in preventing cognitive impairment and to elucidate the underlying mechanism. Randomized controlled animal trials that established the efficacy of moxibustion in preventing cognitive impairment were included in the analysis. Results of behavioral tests and the signaling pathways elucidated were extracted and a meta-analysis was conducted with the behavioral test results. The risk of bias was evaluated using 9 items, and reporting quality was evaluated using the ARRIVE (Animal Research: Reporting In Vivo Experiments) Guidelines Checklist. Ten trials involving 410 animals met the inclusion criteria. All studies reported the benefit of moxibustion in preventing cognitive deficits caused by Alzheimer's disease (AD). Among five studies using the Morris water maze test, a significant effect of moxibustion in decreasing the escape time was reported in three studies, increasing the crossing times in four studies, and prolonging the dwelling time in two studies. The effects of moxibustion were demonstrated to be mediated by an increase in the activity of neurotrophins and heat shock protein, modulation of the cell cycle, and suppression of apoptosis and inflammation. However, considering the small number of included studies, the lack of studies investigating entire signaling pathways, and a high risk of bias and low reporting quality, our results need to be confirmed through more detailed studies.

PURPOSE: This study examined the nutrient intake and dietary habits based on breakfast consumption in Korean adolescents. METHODS: The data of the 2013 ~ 2015 Korea National Health and Nutrition Examination Survey (KNHANES) were used in this study. The analysis included 1,281 adolescents aged 12 to 18 years. The subjects were divided into two groups (EBF: eating breakfast, n = 911; SBF: skipping breakfast, n = 370). RESULTS: The EBF group was significantly younger than the SBF group. In addition, the EBF group had a significantly lower frequency of skipping dinner than the SBF group. The EBF group consumed significantly higher levels of most nutrients except for vitamin A than the SBF group. The percent of nutrient intake under the EAR (estimated average requirements) in the EBF group were also significantly lower than that in the SBF group. Moreover, the NAR (nutrient adequacy ratio) and MAR (mean adequacy ratio) of the EBF group were significantly higher than those of the SBP group. The intake of cereal, sugars and sweeteners, vegetables, and eggs in the EBF group was significantly higher than that in the SBF group. CONCLUSION: The habit of skipping breakfast in adolescents leads to a decrease in the total nutrient intake and imbalanced dietary habits. Breakfast consumption in adolescence is very important. Therefore, more studies will be needed to develop nutrition education systematically in Korean adolescents.

Preterm birth (PTB) is a leading cause of perinatal morbidity and mortality globally. PTB rates have increased in South Korea despite reduction in birth rates. A history of PTB is a strong predictor of subsequent PTB and screening of cervical length between 16 0/7 weeks and 24 0/7 weeks of gestation is recommended in women with a singleton pregnancy and a prior spontaneous PTB. However, the prediction and prevention of spontaneous PTBs in women without a prior PTB remain a matter of debate. The scope of this review article comprises cervical screening and prevention strategies for PTB in asymptomatic women without a prior PTB, based on recent evidence and guidelines.

Background: Plastic waste generates pollutants in the process of incineration or landfilling, and accumulates in water or marine organisms, causing adverse effects on the environment and the human body. Recently, various eco-friendly oral hygiene products (Eco-OHPs) such as bamboo toothbrushes and biodegradable plastic toothbrushes have been developed. Therefore, this study aimed to investigate the current level of awareness and purchasing status of eco-OHPs among adults who are interested in eco-friendly products. Methods: This study included adults aged ＞19 years who regularly visited eco-friendly shops and online sites; the online survey links were distributed during their visits to eco-friendly Internet cafés and companies. Of the 22 questions, seven assessed the participants’ general characteristics, three assessed the general oral hygiene care products used, six assessed the level of awareness of Eco-OHPs, and six assessed the purchasing status of Eco-OHPs. Frequency analysis, chi-square test, and regression analysis were performed using SPSS software. Results: Among the respondents, 108 (51.4%) were aware of Eco-OHPs, and 79 (37.6%) had experience purchasing Eco-OHPs. The most common reason for not purchasing was the lack of information about related brands or products (74, 56.5%). The most common platform used in obtaining information was the Internet (general: 31.5%, eco-friendly: 46.3%), such as Social Network Service, Internet cafes, and blogs. The experience in purchasing Eco-OHPs was affected by whether the respondents recognized the possibility of contributing to environmental preservation, availability of vendors, product safety, and the number of eco-friendly products purchased. Conclusion In order to expand the use of Eco-OHPs, various efforts such as promotion of eco-friendly characteristics, determination of related vendors, reliable analysis of product safety, and expansion of product experience opportunities are required.

In an 8-year period at two medical center, 138 patients underwent uterine artery embolization, and 11 of them were diagnosed with uterine necrosis. Among them, three were successfully conceived. However, one of them developed an arteriovenous malformation after an artificial abortion, and another experienced complications, including placenta previa and placenta accreta spectrum, which resulted in early preterm delivery and recurrent postpartum hemorrhage, necessitating subtotal hysterectomy. Therefore, it is crucial to prepare for potential adverse pregnancy outcomes in subsequent pregnancies for patients with a history of uterine necrosis.

BACKGROUND: The AutoVue Innova (Ortho Clinical Diagnostic, Raritan, NJ, USA) is an automatic instrument for blood bank tests, and it has recently been introduced in Korea for the first time at our hospital. This instrument employs column agglutination technology and it performs blood bank tests automatically. We evaluated this instrument and we report on the results. METHODS: We performed ABO/RhD typing and antibody screening for 250 randomly selected samples, and crossmatching for 261 samples with using the AutoVue Innova in parallel with the conventional manual methods. For a sensitivity test, we added 3 samples of A(2)B(3) and 2 samples of weak-D and serially diluted reagent antisera to the test pool and we measured turnaround time (TAT) for the antibody screening test. RESULTS: The concordance rates between AutoVue Innova and the manual methods for ABO/RhD blood typing, antibody screening and crossmatching tests were 99.6%, 100% and 98.9%, respectively. The overall retest rate was 0.5% and the main cause of the discrepancy was revealed to be hemolysis or an inadequate amount of the samples. The overall sensitivity of AutoVue Innova seems to be same as or better than the manual methods. The TAT for the antibody screening test was significantly shorter for the AutoVue Innova (64+/-43 min, n=512) than for the tube method (89+/-57 min, n=99) (P<0.001). CONCLUSION: The test results of AutoVue Innova were accurate and sensitive for the ABO/RhD typing, crossmatching and antibody screening tests. The TAT for the antibody screening test was remarkably shortened up to five times more samples could be tested without an increase of manpower.

BACKGROUND: Two-jaw surgery including mandibular and maxillary backward movement procedures are commonly performed to correct class III malocclusion. Bimaxillary surgery can reposition the maxillofacial bone together with soft tissue, such as the soft palate and the tongue base. We analyzed changes of pharyngeal airway narrowing to ascertain clinical correlations with the prevalence of snoring after two-jaw surgery. METHODS: A prospective clinical study was designed including a survey on snoring and three-dimensional (3D) computed tomography (CT) in class III malocclusion subjects before and after bimaxillary surgery. We conducted an analysis on changes of the posterior pharyngeal space find out clinical correlations with the prevalence of snoring. RESULTS: Among 67 subjects, 12 subjects complained about snoring 5 weeks after the surgical correction, and examining the 12 subjects after 6 months, 6 patients complained about the snoring. The current findings demonstrated the attenuation of the largest transverse width (LTW), anteroposterior length (APL), and cross-sectional area (CSA) following bimaxillary surgery given to class III malocclusion patients, particularly at the retropalatal level. The average distance of maxillary posterior movements were measured to be relatively higher (horizontal distance 3.9 mm, vertical distance 2.6 mm) in case of new snorers. CONCLUSIONS: This study found that bimaxillary surgery could lead to the narrowing of upper airway at the retropalatal or retroglossal level as well as triggering snoring in subjects with class III malocclusion. Based on the current clinical findings, we also found that upper airway narrowing at retropalatal level may contribute to increasing the probability of snoring and that polysonography may need to be performed before orthognathic surgery in subjects with class III malocclusion.

We report a case of group O losing anti-B selectively. A 25-year-old male donated blood; on the donor test an ABO discrepancy was noted, and a further evaluation study was performed. ABO genotyping with an allele specific polymerase chain reaction assay revealed O/O and DNA sequencing of exons 6 and 7 of the ABO gene showed O01/O02. The serum gammaglobulin level was decreased and only 0.2% CD19 pan-B positive lymphocytes were present in a subset of lymphocytes. In a previous donor study, anti-B of the patient was lost from a third donor study and was still not detected.

PURPOSE: We compared the results of total knee arthroplasties combined with lateral retinacular release with those without lateral retinacular release. MATERIALS AND METHODS: Results of 277 total knee arthroplasties from 1996 to 2002, follow up for at least one year ( average follow-up periods : 32 months). Lateral retinacular release was performed in 190 knees (70.1%) and not performed in 87 knees (29.9%). The clinical results of total knee arthroplasties were evaluated by the Knee Scoring System of hospital for Special Surgery (HSS) and range of motion. The patello-femoral complications were evaluated by tilt and displacement of patella at the last follow-up Hughston 's view. Osteonecrosis and fracture of patella were evaluated by simple x-ray. RESULTS: HSS score and range of motion improved postoperatively in both groups, but there was no sig-nificant difference between the two groups. There were 3 cases (3.4%) with patellar subluxations and 1 case (1.1%) with patellar dislocation in the group without lateral retinacular release. There was no avascu-lar necrosis or fracture of patella in either group. CONCLUSION: We suggest that lateral retinacular release can be performed without great risk of potential patellar complications in total knee arthroplasties requiring lateral retinacular release for proper patellar tracking.
