OBJECTIVES: This study was conducted to evaluate the nutrition quotient (NQ) by mother's parenting style which may influence the NQ in preschool children. METHODS: Subjects were 310 mothers and their 4-6 year old children. The questionnaire composed of demographic characteristics, mother's parenting style at meal time and eating behavior as measured by NQ questions. The NQ questions consisted of 19 food behavior checklist items and all items were grouped into 5 factors: balance, diversity, moderation, regularity, and practice. Mother's parenting style was classified by using words for nutrition education at meal time. All data were statistically analyzed by SPSS program (Ver. 23) and the statistical differences in variables were evaluated by Student's t-test, χ²-test, One-way ANOVA. RESULTS: We observed that in children whose mothers use the parenting style at meal time of ‘explanation’ and ‘compliment & cheer up’ had high dietary regularity, diversity, practice. The children of mothers who use the parenting style at meal time of ‘persuasion’ and ‘reward’ were found to have a lower degree of balance, diversity, and practice. Especially, children of ‘reward’ style mothers had lower moderation of dietary life. On the other hand, among the parenting style at meal time of ‘comparison & demand’, ‘treating’ and ‘faire’, there was no significant difference in the NQ factor by each group. NQ grade was higher among those who used more explanation (p < 0.001) and persuasion (p < 0.01) and with use of less persuasion (p < 0.01) and reward (p < 0.01). The positive association observed between the frequency of dietary education of mothers and higher NQ grade indicated the degree of dietary practices of those children. On the other hand, the children of mothers who rarely practice the dietary education at home had lower NQ grade (p < 0.001). CONCLUSIONS: In order to promote children's proper dietary behaviors, it is important to provide nutrition education to children as well as provide guidance on parenting style at meal time.

BACKGROUND: Primary human cytomegalovirus (CMV) infection during pregnancy is a major cause of congenital malformation. We detected primary CMV infection in pregnant Korean women by using an algorithm that comprises CMV IgG, IgM, and IgG avidity tests. METHODS: During a 2-month period, 744 pregnant women who were at 10-19 weeks of gestation were consecutively enrolled in this study. Human anti-CMV IgG and IgM levels in their sera were determined by chemiluminescence immunoassays. Serum samples from the women who were positive for CMV IgG and IgM were assayed by the ARCHITECT CMV IgG avidity test in order to distinguish primary from non-primary CMV infection. Gross examination of the neonates of the women who were positive for CMV IgM was conducted. RESULTS: The seroprevalence of CMV IgG and IgM was estimated to be 98.1% and 1.7%, respectively. The samples from all the women who were positive for CMV IgM or with grey zone results contained high avidity CMV IgG. Seven women with positive CMV IgG and IgM results who completed follow-up up to delivery showed no gross evidence of in utero CMV transmission. CONCLUSIONS: Maternal primary CMV infection was not detected in any of the pregnant women included in this study cohort. CMV IgG avidity test enabled the identification of women who were at a low risk of transmitting CMV infection and provided informative for subsequent pregnancy outcomes. Compared to previous studies, the seroprevalence of CMV IgG antibody across pregnant Korean women remained unchanged.

Blood pressure (BP) measurement plays a pivotal role in veterinary medicine for diagnosing cardiovascular disorders and monitoring anesthesia of animals. Although indirect BP measurement has been widely applied to monitor BP because of its convenience and non-invasiveness, it is still unclear whether indirect BP measurement is compatible with direct BP measurement in minipigs. In addition, the effect of animal posture during BP measurement is not well understood in minipigs despite its importance to cardiovascular performance. Therefore, both systolic and diastolic arterial BPs in minipigs were measured via femoral artery catheterization for direct BP measurement and using a compressive cuff as an indirect BP measurement under the dorsal or right lateral recumbent postures. Numerical values were processed by the Bland-Altman method to calculate the bias ± SD and the limits of agreement (LOA). In accordance with the American College of Veterinary Internal Medicine guidelines, the results between direct and indirect BP measurements were determined as apparent disagreements in both systolic and diastolic arterial BPs under all postures because of large bias ± SD and wide LOA. The results of the present will help prevent misinterpretation of the anesthetized patient's condition during monitoring of BP by indirect measurement.

This study investigated the healthcare status of South Korea and member states of the Organization for Economic Cooperation and Development (OECD). By employing the position value for relative comparison index, healthcare status was measured through the following components: demand, supply, accessibility, quality, and cost. Statistical analysis was conducted through the Mann-Kendall test from analyzing trends from 2000 onwards. Results showed that while Korea, on average, scores higher than the OECD average in most of the investigated components, it is below average in certain indexes including primary care and mental health care. Considering the various health issues that have been raised about these indexes, it is important these components be improved upon by policy-makers.

Croup is a common upper airway infection characterized by a barking cough, stridor, and hoarseness. It is usually caused by viral infection. A small number of croup caused by coronavirus disease 2019 (COVID-19) has been reported in children before the omicron variant surge. Previously reported cases indicated that croup caused by COVID-19 can be treated in the same manner as those with other viral causes. We describe two cases (9-monthold girl and 11-month-old boy) of previously healthy infants who presented with a barking cough and chest retraction and required endotracheal intubation and cardiopulmonary resuscitation. Despite receiving dexamethasone and nebulized racemic epinephrine (NRE) treatment for croup in the emergency department, these patients still developed acute respiratory failure. Reverse transcription polymerase chain reaction (RT-PCR) of nasopharyngeal samples revealed severe acute respiratory syndrome coronavirus 2 (SARSCoV-2) omicron BA.2 variant (Stealth omicron) and no other common respiratory viral pathogens. Both patients were treated with mechanical ventilation, dexamethasone, and NRE in the pediatric intensive care unit. The duration of intubation was 112 hours and 80 hours, respectively. Both patients were discharged without complications. To the best of our knowledge, this is the first report of life-threatening croup produced by the omicron BA.2 variant and confirmed by RT-PCR. We suggest that this SARS-CoV-2 variant may cause severe croup that may not improve with conventional treatment, even in children without underlying diseases.

PURPOSE: A novel retentive type of implant prosthesis that does not require the use of cement or screw holes has been introduced; however, there are few reports examining the biomechanical aspects of this novel implant. This study aimed to evaluate the biomechanical features of cementless fixation (CLF) implant prostheses.MATERIALS AND METHODS: The test groups of three variations of CLF implant prostheses and a control group of conventional cement-retained (CR) prosthesis were designed three-dimensionally for finite element analysis. The test groups were divided according to the abutment shape and the relining strategy on the inner surface of the implant crown as follows; resin-air hole-full (RAF), resin-air hole (RA), and resin-no air hole (RNA). The von Mises stress and principal stress were used to evaluate the stress values and distributions of the implant components. Contact open values were calculated to analyze the gap formation of the contact surfaces at the abutment-resin and abutment-implant interfaces. The micro-strain values were evaluated for the surrounding bone.RESULTS: Values reflecting the maximum stress on the abutment were as follows (in MPa): RAF, 25.6; RA, 23.4; RNA, 20.0; and CR, 15.8. The value of gap formation was measured from 0.88 to 1.19 µm at the abutmentresin interface and 24.4 to 24.7 µm at the abutment-implant interface. The strain distribution was similar in all cases.CONCLUSION: CLF had no disadvantages in terms of the biomechanical features compared with conventional CR implant prosthesis and could be successfully applied for implant prosthesis.

Arterial calcification, characterized by calcium phosphate deposition in the arteries, can be divided into intimal calcification and medial calcification. The former is the predominant form of calcification in coronary artery plaques; the latter mostly affects peripheral arteries and aortas. Both forms of arterial calcification have strong correlations with adverse cardiovascular events. Intimal microcalcification is associated with increased risk of plaque disruption while the degree of burden of coronary calcification, measured by coronary calcium score, is a marker of overall plaque burden. Continuous research on vascular calcification has been performed during the past few decades, and several cellular and molecular mechanisms and therapeutic targets were identified. However, despite clinical trials to evaluate the efficacy of drug therapies to treat vascular calcification, none have been shown to have efficacy until the present. Therefore, more extensive research is necessary to develop appropriate therapeutic strategies based on a thorough understanding of vascular calcification. In this review, we mainly focus on intimal calcification, namely the pathobiology of arterial calcification, and its clinical implications.
