PURPOSE: The purpose of the study was to identify the prevalence, risk factors and clinical meanings of geriatric foot problems and to suggest implications for the future. METHODS: One hundred eighty nine elderly aged 60 and over from institution as well as community were investigated for their foot conditions by means of a questionnaire including general characteristics, self care capacity, risk factors, foot problem checklist, X-ray, podoscopy and foot scan. Descriptive statistics and chi-square-test was performed as appropriate utilizing SPSS version 14. Less than .05 of p-value was adopted as statistical significance level. RESULTS: All subjects had at least one kind of foot problem and the most prevalent ones were nail problems, foot deformities in order. Prevalence of foot pain and edema was relatively low. CONCLUSION: Foot problem in elderly is prevalent and geriatric foot is expected to emerge as one of the most important problems in the geriatric field. Therefore strategies to deal with geriatric foot should be developed and practiced for better quality of life in later life.

2.Mobile application-based dietary sugar intake reduction intervention study according to the stages of behavior change in female college students
Journal of Nutrition and Health 2019;52(5):488-500
PURPOSE: This study examined the effects of a mobile app-based program to reduce the dietary sugar intake according to the stages of the behavioral change in dietary sugar reduction in female college students. METHODS: The program used in this study can monitor the dietary sugar intake after recording the dietary intake and provide education message for the reduction of dietary sugar intake. In an eight-week pre-post intervention study, 68 female college students were instructed to record all the food they consumed daily and received weekly education information. At pre-post intervention, the subjects were asked to answer the questionnaire about sugar-related nutrition knowledge, sugar-intake behavior, and sugar-intake frequency. For statistical analysis, ANOVA and a paired t-test were used for comparative analysis according Precontemplation (PC), Contemplation ·Preparation (C ·P), and A ·M (Action ·Maintenance) stage. RESULTS: Significant differences were observed in the frequency of snacking, experience of nutrition education, and preference for sweetness according to the stages of behavior change in dietary sugar reduction. After finishing an intervention, the sugar-related nutrition knowledge score was increased significantly in the stages of Precontemplation (PC) and Contemplation ·Preparation (C ·P). The score of the sugar intake behavior increased significantly in all stages. The intake frequency of chocolate, muffins or cakes, and drinking yogurt decreased significantly in the PC stage and the intake frequency of biscuits, carbonated beverages, and fruit juice decreased significantly in the C ·P stage. Subjects in the PC and C ·P stages had an undesirable propensity in nutrition knowledge, sugar-intake behavior, and sugar-intake frequency compared to the A ·M stage, but this intervention improved significantly their nutrition knowledge, sugar-intake behavior, and sugar-intake frequency. CONCLUSION: This program can be an effective educational tool in the stages of PC and C ·P, and is expected to further increase the usability and sustainability of mobile application if supplemented appropriately to a health platform program.

There have been few reports on chromosomal abnormalities in secondary hemophagocytic lym-phohistiocytosis (HLH) including Epstein-Barr virus-associated HLH (EBV-HLH). Clonality of HLH can be determined by karyotypic analysis, T-cell receptor or IgH rearrangement studies, and EBV genome terminal repeat investigation. Chromosome analysis in EBV-HLH is the most important tool currently available for assessment of case-by-case prognosis. We report a case of fatal EBV-HLH with clonal karyotype abnormality. A 57-year-old man was admitted with persistent high fever and hepatosplenomegaly. Laboratory data revealed pancytopenia, hypofibrinogenemia, coagulation abnormalities, and marked abnormalities of liver function tests. EBV-DNA was detected in the bone marrow by PCR. The bone marrow studies showed mature, benign-looking histiocytic hyperplasia with prominent hemophagocytosis and clonal chromosomal abnormality. Although the patient was treated with immunochemotherapy and antibiotics, he died of disseminated intravascular coagu-lopathy and sepsis. Considering this fatal clinical course, it is important to take intensive therapeutic measures if karyotype abnormality is noted in the treatment of EBV-HLH cases.

The CD56 antigen is a cell adhesion molecule and its expression on tumor cells is thought to play a role in CD56-positive lymphomas and leukemias with unusual sites of involvement. As to chronic myelogenous leukemia (CML) and related blastic crisis, CD56 expression is not generally considered as a part of the CML phenotype and has rarely been reported in CML and other chronic myeloproliferative dirsorders (CMPD). We reported a case of CML expressing the CD56 antigen on the CD34-negative myeloid cells presented with extramedullary granulocytic sarcoma and examined the CD56 reactivity on bone marrow biopsy sections in 9 patients with CMPD. To assess the abnormal expression of the CD56 antigen on myeloid and progenitor cells from CMPD, immunohistochemical staining and flow cytometric analysis were performed on bone marrow biopsy sections and aspirate specimens, respectively. Of nine patients with CMPD, a case of CML in blastic crisis with extramedullary granulocytic sarcoma showed an abnormal expression of CD56 on CD34-negative myeloid cells. The expression of CD56 on CML myeloid elements seems to represent an aberrant phenomenon that could affect the pattern of tumor cell dissemination.

When treating trauma patients with severe hemorrhage, massive transfusions are often needed. Damage control resuscitation strategies can be used for such patients, but an adequate fresh frozen plasma: packed red blood cell (FFP:PRBC) administration ratio must be established. We retrospectively reviewed the medical records of 100 trauma patients treated with massive transfusions from March 2010 to October 2012. We divided the patients into 2 groups according to the FFP:PRBC ratio: a high-ratio (> or =0.5) and a low-ratio group (<0.5). The patient demographics, fluid and transfusion quantities, laboratory values, complications, and outcomes were analyzed and compared. There were 68 patients in the high-ratio and 32 in the low-ratio group. There were statistically significant differences between groups in the quantities of FFP, FFP:PRBC, platelets, and crystalloids administered, as well as the initial diastolic blood pressure. Bloodstream infections were noted only in the high-ratio group, and the difference was statistically significant (P=0.028). Kaplan-Meier plots revealed that the 24-hr survival rate was significantly higher in the high-ratio group (71.9% vs. 97.1%, P<0.001). In severe hemorrhagic trauma, raising the FFP:PRBC ratio to 0.5 or higher may increase the chances of survival. Efforts to minimize bloodstream infections during the resuscitation must be increased.

BACKGROUND: We analyzed the data for primary total hip arthroplasty (THA) in the Korean nationwide database to assess (1) the epidemiology and national trends of bearing surface usage in THAs and (2) the prevalence of each type of bearing surface according to age, gender, hospital type, primary payer, and hospital procedure volume. METHODS: A total of 30,881 THAs were analyzed using the Korean Health Insurance Review and Assessment Service database for 2007 through 2011. Bearing surfaces were sub-grouped according to device code for national health insurance claims and consisted of ceramic-on-ceramic (CoC), metal-on-polyethylene (MoP), ceramic-on-polyethylene (CoP), and metal-on-metal (MoM). The prevalence of each type of bearing surface was calculated and stratified by age, gender, hospital type, primary payer, and procedure volume of each hospital. RESULTS: CoC was the most frequently used bearing surface (76.7%), followed by MoP (11.9%), CoP (7.3%), and MoM (4.1%). The proportion of THAs using a CoC bearing surface increased steadily from 71.6% in 2007 to 81.4% in 2011, whereas the proportions using CoP, MoP, and MoM bearing surfaces decreased. The order of prevalence was identical to that in the general population regardless of age, gender, hospital type, primary payer, and hospital procedure volume. CONCLUSIONS: The trends and epidemiology of bearing surface usage in THAs in Korea are different from those in other countries, and the CoC bearing surface is the most prevalent articulation. In future, the results of a large-scale study using nationwide data of THAs involving a CoC bearing surface will be reported in Korea.

Myelofibrosis results from stimulation of bone marrow stromal fibroblasts by fibrogenic cytokines elaborated by neoplastic or reactive cells in the marrow. Chronic idiopathic myelofibrosis should be differentiated from secondary myelofibrosis resulting from bone marrow involvement of malignant lymphoma because these diseases have different therapeutic strategies. Myelofibrosis in systemic lupus erythematosus is an uncommon but well-recognized complication, and identifying an autoimmune myelofibrosis is important in diagnosing this benign cause of myelofibrosis. We report two cases of myelofibrosis presenting the clinical and radiologic findings that mimicked malignant lymphoma -a case of autoimmune myelofibrosis associated with systemic lupus erythematosus showing extensive lymphadenopathy and a case of chronic idiopathic myelofibrosis with focal intrasplenic extramedullary hematopoiesis- and discuss the importance of the clinical information and radiologic findings for the pathologic diagnosis of myelofibrosis.

BACKGROUND: Coffee is one of the most widely consumed beverages in the world, and contains caffeine and phenolic compounds. Many studies on the association between coffee consumption and risk of stroke have been reported, however, more research is needed to further explore many studies' inconsistent results. Therefore, we conducted a meta-analysis to verify the relationship between coffee consumption and stroke. METHODS: We searched MEDLINE (PubMed), EMBASE, and the Cochrane Library, using the keywords "coffee" or "caffeine" for the exposure factors, and "transient ischemic attack" or "stroke" or "acute cerebral infarction" or "cardiovascular events" for the outcome factors. We included prospective cohort and case-control studies published between 2001 and July 2011 in this review. The search was limited to English language. RESULTS: Among 27 articles identified for this review, only 9 studies met the inclusion criteria, all of which were cohort studies. When using all cohort studies, the pooled relative risk (RR) of stroke for the highest vs. lowest category of coffee consumption was 0.83 (95% confidence interval [CI], 0.76 to 0.91). When subgroup analysis was performed, for Europeans, increased coffee drinking showed a preventive effect on stroke occurrence with RR 0.82 (95% CI, 0.74 to 0.92); RR for women 0.81 (95% CI, 0.70 to 0.93); for ischemic stroke 0.80 (95% CI, 0.71 to 0.90); and for those drinking 4 cups or more per day 0.83 (95% CI, 0.75 to 0.91). CONCLUSION: We found that coffee consumption of 4 cups or more per day showed a preventive effect on stroke in this meta-analysis.

Despite decades of research on Alzheimer disease, understanding the complexity of the genetic and molecular interactions involved in its pathogenesis remains far from our grasp. Methyl-CpG Binding Protein 2 (MeCP2) is an important epigenetic regulator enriched in the brain, and recent findings have implicated MeCP2 as a crucial player in Alzheimer disease. Here, we provide comprehensive insights into the pathophysiological roles of MeCP2 in Alzheimer disease. In particular, we focus on how the alteration of MeCP2 expression can impact Alzheimer disease through risk genes, amyloid-β and tau pathology, cell death and neurodegeneration, and cellular senescence. We suggest that Alzheimer disease can be adversely affected by upregulated MeCP2-dependent repression of risk genes (MEF2C, ADAM10, and PM20D1), increased tau accumulation, and neurodegeneration through neuronal cell death (excitotoxicity and apoptosis). In addition, we propose that the progression of Alzheimer disease could be caused by reduced MeCP2-mediated enhancement of astrocytic and microglial senescence and consequent glial SASP (senescence-associated secretory phenotype)-dependent neuroinflammation. We surmise that any imbalance in MeCP2 function would accelerate or cause Alzheimer disease pathogenesis, implying that MeCP2 may be a potential drug target for the treatment and prevention of Alzheimer disease.

Objective:
This study aimed to investigate the impact of coronavirus disease-2019 (COVID-19) on suicide attempts and suicide deaths in South Korea, focusing on age and sex differences.
Methods:
We analyzed the monthly number of suicide attempts and suicide deaths during pre-pandemic (January 2016–February 2020) and pandemic (March–December 2020) periods using nationally representative databases. We conducted an interrupted time series analysis and calculated the relative risk (RR) with a 95% confidence interval (CI), categorizing subjects into adolescents (<18), young adults (18–29), middle-aged (30–59), and older adults (≥60).
Results:
During the pandemic, the number of suicide attempts abruptly declined in adolescents (RR [95% CI] level change: 0.58 [0.45–0.75]) and older adults (RR [95% CI] level change: 0.74 [0.66–0.84]). In older males, there was a significant rebound in the suicide attempt trend (RR [95% CI] slope change: 1.03 [1.01–1.05]). The number of suicide deaths did not change among age/sex strata significantly except for older males. There was a brief decline in suicide deaths in older males, while the trend showed a following increase with marginal significance (RR [95% CI] level change: 0.76 [0.66–0.88], slope change: 1.02 [1.00–1.04]).
Conclusion
This study suggests the heterogeneous impact of the COVID-19 pandemic on suicide attempts and suicide deaths across age and sex strata in South Korea. These findings highlight the need for more targeted mental health interventions, given the observed trends in suicide attempts and suicide deaths during the pandemic.
