1.Adiponectin as a new paradigm for approaching Alzheimer's disease.
Anatomy & Cell Biology 2013;46(4):229-234
Adiponectin is an adipocytokine released by the adipose tissue and has multiple roles in the immune system and in the metabolic syndromes such as cardiovascular disease, Type 2 diabetes, obesity and also in the neurodegenerative disorders including Alzheimer's disease. Adiponectin regulates the sensitivity of insulin, fatty acid catabolism, glucose homeostasis and anti-inflammatory system through various mechanisms. Previous studies demonstrated that adiponectin modulates memory and cognitive impairment and contributes to the deregulated glucose metabolism and mitochondrial dysfunction observed in Alzheimer's disease. Here, we aim to summarize recent studies that suggest the potential correlation between adiponectin and Alzheimer's disease.

OBJECTIVES: This study aims to investigate the factors related to Korean physicians' trust in the government. METHODS: We used structured questionnaires that were composed of multidimensional scales for each of the various categories. RESULTS: The recognition levels of trust of the government by Korean physicians were not high, and they ranged from 3.6 to 4.8 for ten scales. The factors related to trust in the government were categorized into seven factors on the basis of a factor analysis. On the regression analysis, a positive relationship was found between "the individual propensity to trust" and trust in the government, while a negative relationship was found between "the recognition level regarding the government as an authoritarian power" and trust in the government. "Confidence about participation in the policy process" as internal efficacy and "belief in governmental ability and motivation toward public demand" as external efficacy also showed a strong positive relationship with trust in the government. CONCLUSIONS: From these results, we can draw the conclusion that making efforts to improve the recognition level of trust in the government among physicians is an important policy task. To increase the trust level, participation of physicians in the policy process in various ways and open communication between the physicians'associations and the government should be facilitated.

Microglia regulate the secretion of various immunomediators in central nervous system diseases. Microglial autophagy is the crucial process for cell's survival and cytokine productions. Recent studies have reported that several microRNAs are involved in the autophagy system. miR-Let7A is such a microRNA that plays a role in various inflammation responses, and is magnified as a key modulator particularly in the autophagy system. In present study, we investigated whether miR-Let7A is involved in autophagy in activating microglia. Overexpression of miR-Let7A in LPS-stimulated BV2 microglial cells promoted the induction of the autophagy related factors such as LC3II, Beclin1, and ATG3. Our results suggest a potential role of miR-Let7A in the autophagy process of microglia during CNS inflammation.

PURPOSE: This study aimed to develop and evaluate the lower extremity lymphedema nursing practice protocol for patients following gynecologic cancer treatment. METHODS: Thirteen web-sites were searched for eligible clinical practice guidelines (CPGs) and eleven databases were searched to identify evidence to develop a lower extremity lymphedema nursing practice protocol for patients following gynecologic cancer treatment. RESULTS: Based on the inclusion and exclusion criteria, eight CPGs and ninety-six studies, two guidelines and eight studies were identified as evidence. The protocol development group consisted of ten experts who have at least five years' experience in the related area. A lower extremity lymphedema nursing practice protocol for patients following gynecologic cancer treatment was developed including forty-three recommendations in five domains. Significant differences were found in nurses' pre and post knowledge and confidence on lower extremity lymphedema prevention and management. CONCLUSION: Nurses and other professionals could utilize this evidence based lower extremity lymphedema nursing practice protocol and apply it to patients undergoing gynecologic cancer treatment.

Osteoarticular infections due to non-typhoidal Salmonella are rare, occurring with an incidence rate of 0.1-0.2%. An immunocompromised state and the existence of sickle cell anemia are known risk factors for development of septic arthritis due to Salmonella. In this report, we describe a patient with septic arthritis of the left knee caused by non-typhoidal Salmonella . An 82-year-old woman visited the emergency room presenting with left knee pain, fever and dyspnea. The patient had osteoarthritis and was treated with oral analgesics, but not with an intra-articular injection. Upon assessment of the patient's joint fluid and blood culture results, non-typhoidal Salmonella (Salmonella group D) was detected. Arthroscopy-guided irrigation and debridement, and administration of oral antibiotics (fluoroquinolone) over six weeks were required in order to achieve a full recovery from the infection.

The aim of this study was to determine the efficacy of a 3 tone plaque disclosing gel in assessing the risk of caries related to the population of Streptococcus mutans, Streptococcus sobrinus, and Lactobacillus spp. quantified using a quantitative real-time polymerase chain reaction (qRT-PCR).15 healthy children of ages 9 – 12 years were randomly examined. The 3 tone plaque disclosing gel was applied on teeth surfaces, which changed the color to pink or red, blue or purple and light blue. Plaque was divided into 3 groups based on staining. Genomic DNA from each sample was subjected to a qRT-PCR assay for quantitative detection of target bacteria. The Kruskal-Wallis test was conducted for correlation between the color of plaque and the number of bacterial species.The levels of S. mutans, S. sobrinus, and Lactobacillus spp. were significantly different in the plaque samples of the 3 groups (p < 0.05). The proportion of S. sobrinus to S. mutans showed correlation to the color of plaque.The different color-dyed plaque was related to the number of acidogenic bacteria. The 3 tone plaque disclosing gel could be used as one of the indicators to assess the clinical risk of caries associated with the population of S. mutans, S. sobrinus, and Lactobacillus spp.

Objectives:
The Panbio COVID-19 Ag Rapid Test Device (Panbio COVID-19 Ag, Abbott Rapid Diagnostics) is a lateral flow immunochromatographic assay targeting the severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2) nucleoprotein in nasopharyngeal specimens for the diagnosis of coronavirus disease 2019 (COVID-19). This study aimed to verify the performance of the Panbio COVID-19 Ag for implementation in clinical laboratories.
Methods:
Sixty nasopharyngeal swab specimens (30 positive and 30 negative) dipped in transport medium, and COVID-19 was confirmed using real-time RT-PCR using Allplex SARS-CoV-2 assay (Seegene), were tested using the Panbio COVID-19 Ag. Reproducibility was evaluated using positive and negative control materials. Sensitivity and specificity were calculated based on the results of realtime RT-PCR as the standard test method.
Results:
Reproducibility was confirmed by the consistent results of repeated tests of the quality control materials. The overall sensitivity and specificity of Panbio COVID-19 Ag were 50.0% and 100.0%, respectively. Panbio COVID-19 Ag demonstrated high sensitivity (88.2%) in analyzing the detection limit cycle threshold (Ct) value of 26.67 provided by the manufacturer as a positive criterion, and the sensitivity was 100.0% for the positive criterion of Ct values <25, although it was less sensitive for Ct ≥ 25.
Conclusion
Considering the high sensitivity for positive samples with Ct values <25 and the rapid turnaround of results, Panbio COVID-19 Ag can be used in clinical laboratories to diagnose COVID-19 in limited settings.

The association between celebrity suicide and subsequent increase in suicide rates among the general population has been suggested. Previous studies primarily focused on celebrity suicides in the 2000s. To better understand the association, this study examined the impacts of celebrity suicides on subsequent suicide rates using the data of Korean celebrity suicides between 1990 and 2010. Nine celebrity suicides were selected by an investigation of media reports of suicide deaths published in three major newspapers in Korea between 1990 and 2010. Suicide mortality data were obtained from the National Statistical Office of Korea. Seasonal autoregressive integrated moving average models with intervention analysis were used to test the impacts of celebrity suicides, controlling for seasonality. Six of the 9 celebrity suicides had significant impacts on suicide rates both in the total population and in the same gender- or the same age-subgroups. The incident that occurred in the 1990s had no significant impact on the overall suicide rates, whereas the majority of the incidents in the 2000s had significant influences for 30 or 60 days following each incident. The influence of celebrity suicide was shown to reach its peak following the suicide death of a renowned actress in 2008. The findings may suggest a link between media coverage and the impact of celebrity suicide. Future studies should focus more on the underlying processes and confounding factors that may contribute to the impact of celebrity suicide on subsequent suicide rates.

PURPOSE: This study aims to compare and investigate the differences in beliefs with regard to the cause of illnesses, medial skepticism, and attitudes toward medical care between medical, Oriental medical, and nonmedical students. METHODS: To this end, we used a structured questionnaire and collected self-reported data from a sample of 667 respondents. RESULTS: First, their beliefs on the causes of illness were markedly different, depending on their specialty. Compared with students from other specialties, Oriental medical students ranked host factors, environmental factors, and natural factors as the highest causes of illness. -the former group regarded supernatural factors as a more influential cause of illnesses compared with the latter. Among Oriental medical students and nonmedical students-who were also subdivided into the aforementioned groups-the upper-grade group regarded host factors as a higher cause of illness than the lower-grade group. Second, Medical skepticism also differed depending on specialty. Compared with the medical students, Oriental medical students were more likely to have high confidence in "overcoming illnesses", "home remedies", "self-decision in treatments", and "understanding their own health". In subdividing medical and Oriental medical students according to grade we observed that the senior group had more confidence in home remedies than the junior group. Third, In an analysis of the students attitudes toward medical care, we found that nonmedical students had the highest score in the "care-oriented" and "cure-oriented" attitude categories. In the overall results, the care-oriented category ranked highest for the nonmedical students, followed by Oriental medical students and medical students; the cure-oriented category ranked highest for nonmedical students, followed by medical students and then Oriental medical students. CONCLUSION: Based on our results, we conclude that these differences between specialties should be reflected in medical curricula to bridge the gap between patients and doctors in medical education with regard to the causes of illness and attitudes toward medical care.
