BACKGROUND: In the life cycle, bone mineral density (BMD) is the most optimal condition in the 20s. In Korea, vitamin D deficiency status is very serious in Korean women due to recent lack of activity, weight polarization, and inadequate nutritional intake. The purpose of this study was to compare serum vitamin D and BMD according to obesity status in Korean young adult women. METHODS: A total of 143 female college students participated in the research. Body fat and lean body status were analyzed using a body composition analyzer. Nutrient intakes of the subjects were assessed by 3-days food record method. The BMDs was measured by dual energy X-ray absorptiometry. The subjects were divided into normal weight group and obesity group on their body mass index. RESULTS: Obesity group showed significantly higher weight, body fat (%), and body fat (kg) than normal weight group and T-scores of lumbar-2 spines were significantly lower. Obesity group showed high triglyceride and low-density lipoprotein cholesterol levels and vitamin D levels were significantly lower. Physical fitness and activity status showed that sit and reach and sit up were significantly lower in obesity group. The intake of carbohydrates was higher in the obesity group than in the normal weight group, and the intake of vitamin C and vitamin D was significantly lower. Factors affecting serum vitamin D were analyzed as body fat (%), lumbar-2 T-score, triglyceride, and carbohydrate intake. CONCLUSIONS: Obese women need more effort to manage their serum vitamin D status and balanced nutrition to prevent bone loss.

Echovirus 30 is one of the major causes of meningitis in children and adults. The purpose of our current study was to investigate whether selected antiviral drugs could provide antiviral activity against echovirus 30. Using RD cells, we assessed the cytopathic effect of echovirus 30, including viral RNA levels as indicators of viral replication. The effects of gemcitabine were compared to rupintrivir, a well-known antiviral drug. To understand the activity gemcitabine exerts on the viral life cycle, time course and time-of-addition assays were implemented. The most effective compounds against echovirus 30 were gemcitabine and rupintrivir, as demonstrated by their concentration-dependent activity. Gemcitabine affects the early stages of echovirus 30 infection by disrupting viral replication. However, gemcitabine failed to directly inactivate echovirus 30 particles or impede viral uptake into the RD cells. Gemcitabine can be considered as a lead candidate in the development of echovirus 30 antiviral drugs, specifically in the early stages of echovirus 30 replication.

Toxoplasmosis is a cosmopolitan zoonotic infection, caused by a unicellular protozoan parasite known as Toxoplasma gondii that belongs to the phylum Apicomplexa. It is estimated that over one-third of the world's population has been exposed and are latently infected with the parasite. In humans, toxoplasmosis is predominantly asymptomatic in immunocompetent persons, while among immunocompromised individuals may be cause severe and progressive complications with poor prognosis. Moreover, seronegative pregnant mothers are other risk groups for acquiring the infection. The life cycle of T. gondii is very complex, indicating the presence of a plurality of antigenic epitopes. Despite of great advances, recognize and construct novel vaccines for prevent and control of toxoplasmosis in both humans and animals is still remains a great challenge for researchers to select potential protein sequences as the ideal antigens. Notably, in several past years, constant efforts of researchers have made considerable advances to elucidate the different aspects of the cell and molecular biology of T. gondii mainly on microneme antigens, dense granule antigens, surface antigens, and rhoptry proteins (ROP). These attempts thereby provided great impetus to the present focus on vaccine development, according to the defined subcellular components of the parasite. Although, currently there is no commercial vaccine for use in humans. Among the main identified T. gondii antigens, ROPs appear as a putative vaccine candidate that are vital for invasion procedure as well as survival within host cells. Overall, it is estimated that they occupy about 1%–30% of the total parasite cell volume. In this review, we have summarized the recent progress of ROP-based vaccine development through various strategies from DNA vaccines, epitope or multi epitope-based vaccines, recombinant protein vaccines to vaccines based on live-attenuated vectors and prime-boost strategies in different mouse models.

PURPOSE: This study aimed to develop a web-based cost management program for visiting nursing centers (CMP-VNC), using time-driven activity-based costing (TD-ABC), and to analyze effects of the program. METHODS: The CMP-VNC was developed using the combined prototyping approach and system developing life cycle method following four stages: need analysis with comprehensive literature reviews and focus group interviews, design and development of program algorithm, evaluation of the developed program validity using experts and users group, and application and effects analysis. The non-equivalent control group pretest-posttest design was used to analyze the effects of the program. The program demonstration was conducted for four weeks with 60 visiting nurses in 35 visiting centers. RESULTS: The web-based program was developed. It has five interfaces with basic and special functions using TD-ABC, namely, input, visiting nursing activity, visiting nursing activity cost, cost efficiency, and cost calculation report. The experimental group showed significantly higher cost perception and cost confidence than control group. CONCLUSION: We found that the CMP-VNC can be an effective tool to increase visiting nurses' competency of costing and enhance efficiencies of visiting nursing centers.

Toxoplasma gondii belongs to the Apicomplexa phylum that caused a widespread zoonotic infection in wide range of intermediate hosts. Over one-third of the world's population are latently infected with T. gondii and carry it. The complex life cycle of T. gondii indicates the presence of a plurality of antigenic epitopes. During the recent years, continuous efforts of scientists have made precious advances to elucidate the different aspects of the cell and molecular biology of T. gondii. Despite of great progresses, the development of vaccine candidates for preventing of T. gondii infection in men and animals is still remains a challenge. The calcium-dependent protein kinases (CDPKs) belongs to the superfamily of kinases, which restricted to the apicomplexans, ciliates, and plants. It has been documented that they contribute several functions in the life cycle of T. gondii such as gliding motility, cell invasion, and egress as well as some other critical developmental processes. In current paper, we reviewed the recent progress concerning the development of CDPK-based vaccines against acute and chronic T. gondii.

BACKGROUND: The importance of bone health is emphasized throughout the life cycle. Young adults have problems with bone health due to irregular lifestyle and unbalanced diet, but studies related to them are insufficient. The purpose of this study was to measure the bone mineral density (BMD) of college students and to analyze the differences in BMD according to lifestyle. METHODS: BMD was measured by bone ultrasound in 161 male and female college students. The questionnaire was surveyed about lifestyle, eating habits, and nutrient intake status. RESULTS: Osteopenia was 8.8% in male and 10.8% in female. The body fat percentage of female was significantly higher than male. Male college students, smoking, fast food consumption, and overeating rate were significantly higher than female. Nutrient intake was not significantly different between male and female students. But energy and vitamin A and C levels were inadequate, and protein and sodium intake was excessive compared with the recommended nutrient intake for Koreans. BMD was significantly lowest in male who often intake fast food than male who did not intake at all or intake sometimes. Female who often intake fast food had significantly lower BMD than female who did not eat at all. CONCLUSIONS: College students have different BMDs according to lifestyle. There was a difference in BMD according to smoking and fast food consumption.

OBJECTIVES: This study developed a diabetes self-management mobile application based on the information-motivation-behavioral skills (IMB) model, evidence extracted from clinical practice guidelines, and requirements identified through focus group interviews (FGIs) with diabetes patients. METHODS: We developed a diabetes self-management (DSM) app in accordance with the following four stages of the system development life cycle. The functional and knowledge requirements of the users were extracted through FGIs with 19 diabetes patients. A system diagram, data models, a database, an algorithm, screens, and menus were designed. An Android app and server with an SSL protocol were developed. The DSM app algorithm and heuristics, as well as the usability of the DSM app were evaluated, and then the DSM app was modified based on heuristics and usability evaluation. RESULTS: A total of 11 requirement themes were identified through the FGIs. Sixteen functions and 49 knowledge rules were extracted. The system diagram consisted of a client part and server part, 78 data models, a database with 10 tables, an algorithm, and a menu structure with 6 main menus, and 40 user screens were developed. The DSM app was Android version 4.4 or higher for Bluetooth connectivity. The proficiency and efficiency scores of the algorithm were 90.96% and 92.39%, respectively. Fifteen issues were revealed through the heuristic evaluation, and the app was modified to address three of these issues. It was also modified to address five comments received by the researchers through the usability evaluation. CONCLUSIONS: The DSM app was developed based on behavioral change theory through IMB models. It was designed to be evidence-based, user-centered, and effective. It remains necessary to fully evaluate the effect of the DSM app on the DSM behavior changes of diabetes patients.

The family Thapariellidae has been reported in only 3 countries since 1990. The objective of this study was to identify Thapariella anastomusa metacercariae in snails in Thailand based on morphological traits using a light (LM) and a scanning electron microscope (SEM). A total of 94 Filopaludina snails were collected and identified as 50 F. martensi martensi and 44 F. doliaris. Metacercariae of T. anastomusa were recovered from the snails by the crushing method. The overall prevalence was 22.3% (21/94), and the mean intensity was 17.0 per snail. The prevalence in F. martensi martensi was 24.0% (12/50) and F. doliaris 20.5% (9/44) with the mean intensity of 18.8 and 14.8 per snail, respectively. SEM revealed traits such as a concave ventral body and well-developed oral and ventral suckers. This study represents the first report of T. anastomusa in South East Asia. While LM and SEM observations provide novel insights into T. anastomusa metacercarial morphology and life history, the trematode’s life cycle remains unclear. To date, there has been no report of T. anastomusa causing infections in humans. However, the snails F. martensi martensi and F. doliaris carrying the infective stages of T. anastomosa are frequently consumed by Thai people. This consumption, particularly uncooked snails, may present a risk of Thapariella infections in humans.
