A bibliometric study is performed to analyze publication patterns in a specific research area and to establish a landscape model that can be used to quantitatively weigh publications. This study aimed to investigate AML research networks and to conduct a trend-related keyword analysis. We analyzed 48,202 studies about AML published from 1999 to 2019 in the Web of Science Core Collection. The network analysis was conducted using the R&R studio software. The journal Blood had the highest number of published articles with an h-index of 410. The USA had the highest number of total publications (18,719, 38.3%) and research funded by the government, institutions, and pharmaceutical companies (5,436, 10.8%). The institute with the largest number of publications was the MD Anderson Cancer Center. Kantarjian H, Garcia-Manero G, and Ravandi F were the leading authors of publications about AML. Keyword analysis revealed that FLT 3, micro-RNA, and NK cell topics were the hotspots in the cell and gene area in all publications. The overall AML research landscape is popular in the field of translational research as it can identify molecular, cell, and gene studies conducted by different funding agencies, countries, institutions, and author networks. With active funding and support from the Chinese government, the productivity of scientific research is increasing not only in the AML field but also in the medical/health-related science field.

OBJECTIVE: The purpose of this study was to evaluate the levels of DNA damage in human lymphocytes caused by smoking and other lifestyle factors. METHODS: The study population consisted of 173 normal healthy male adults from 21 to 59 years old. The demographic and lifestyle variables were obtained from administered questionnaires. The level of lymphocytic DNA damage in the peripheral blood was evaluated by the Comet assay. Statistical analyses were done by general linear model analysis and Dunnett's multiple comparison. RESULTS: The difference in DNA damage between smokers and non-smokers was statistically significant. The means for the Tail%DNA were found to be 10.48 in the current smokers and 9.60 in the non-smokers (p<0.05). The tail moment means were 1.58 and 1.45 (p<0.05) for the current smokers and non-smokers, respectively. The number of cigarettes smoked per day did not result in a significant difference in the level of DNA damage among the smokers. Other lifestyle factors such as age, and drinking and exercise habits were not related to DNA damage. CONCLUSIONS: The DNA damage in the lymphocytes of smokers was found to be significantly higher than that for non-smokers. However, the number of cigarettes smoked per day was not related to DNA damage. Further study is needed to evaluate the relationship between the amount of smoking and level of damage to DNA. In addition, the status of DNA repair activities should be assessed.

Hypertension is one of the most well known risk factors for cerebrovascular or coronary heart disease and is a major public health problem. Early detection and treatment of hypertension are essential, but the compliance of treatment on hypertension is not easy to archive. Hypertensive workers are being detected by the annual screening under the Labour Standard Law in Korea but the solidified control system for them is not existing. This study about workers' Motive- Belief-Action in non-drug and drug treatment of their hypertension would be worthwhile to interpret how the workers actually behave in coping with hypertension, and also would be advisable to construct the follow-up program in Korea. In the field research process two criteria were used to select sample group. The first criterion included the workers who were screened to be hypertensive with their blood pressure above 160/95 in this survey. The second one was used to classify study-group respondents who had known their hypertension by successive annual screening. From such criteria a total of 156 male workers were sampled in 21 industries, the author interviewed them using the structured questionnaire which consisted of Belief-Motive-Action items about non-drug and drug treatment for hypertension with open-ended question on symptom of hypertension. The summary is as follows: 1) Sixty-one percent of respondents had ever checked their blood pressure somewhere besides the annual screening. 2) Most respondents(97.2%) complained no symptoms of hypertension at all. 3) Belief level of non-drug treatment was relatively high (82.1%-64.7%), but motive (55.1%-28.2%) and action (38.5%-16.7%) levels were low. 4) Belief level of drug treatment was relatively lower than that of non-drug treatment, blue collar workers showed higher action level of drug treatment than white collar workers, and correlation coefficient between belief and motive on drug treatment was lower in group of not-recognizing their family history of hypertension than recognized group. Such findings indicated that belief on drug treatment of hypertensive workers would be problematic. 5) White collar workers showed significant lower correlation coefficients between Motive and Action of salt restriction, restriction of fatty diet and relaxation than blue collar workers. 6) Mild hypertension group showed low levels of Motive and Action of non-drug treatment (salt restriction, restriction of fatty diet and relaxation) and also showed low correlation coefficient between Belief and Motive of above non-drug treatment.

Journal of Korean Medical Science 1996;11(4):319-325
The determination of adjustment method of urinary mercury in spot urine is one of the important issues in assessing the health risks of mercury workers. But there have been debates about whether creatinine or other forms of correction for urinary concentration are better in reducing the variation of urinary mercury. We evaluated four adjustment methods-specific gravity, creatinine, log creatinine and excretion rate-by correlation between values adjusted by the four methods and individual exposure levels which were the geometric mean of daily air mercury level for 2 or 5 days, and mercury concentrations in 24 hour urine were also investigated to compare the results of spot urine. The correlation between values of spot urine and mercury exposure level was over 0.8 in all adjustment methods for workers who worked over 1 year. All four adjustment methods for urinary mercury were found to be similar in assessing the exposure, log creatinine and excretion rate method however were not practical to use due to lack of reference values, and variable standard values of specific gravity. And the creatinine adjusted values were more sensitive in low mercury exposure level. We therefore recommend the creatinine adjustment method for adjustment of urinary mercury.

2,3,7,8-tetrachlorodibenzo-p-dioxin (TCDD) can induce drug transporter genes such as the ATP-binding cassette G member 2 (ABCG2), which contributes to multidrug resistance. We investigated the effect of TCDD pretreatment on drug transporters induction from cancer cells of various origins. Cell viabilities after treatment of cisplatin were measured to evaluate acquiring cisplatin resistance by TCDD. Acquring cisplatin resistance was found only in cisplatin senstivie cancer cells including gastric SNU601, colon LS180, brain CRT-MG and lymphoma Jurkat cells which showed a significant increase in cell viability after combined treatment with TCDD and cisplatin. High increase of ABCG2 gene expression was found in SNU601 and LS180 cells with a mild increase in the expression of the ABCC3, ABCC5,and SLC29A2 genes in SNU601 cells, and of major vault protein (MVP) in LS180 cells. The AhR inhibitor kaempferol suppressed the upregulation of ABCG2 expression and reversed the TCDD-induced increase in cell viability in LS180 cells. However, in CRT-MG cells, other transporter genes including ABCC1, ABCC5, ABCA3, ABCA2, ABCB4, ABCG1, and SLC29A1 were up-regulated. These findings suggested the acquiring cisplatin resistance by TCDD associated with cancer cell-type-specific induction of drug transporters.

Background:
The purpose of the current study was to evaluate and compare the effectiveness of a cryopneumatic compression device with that of standard ice packs following arthroscopic anterior cruciate ligament (ACL) reconstruction, with a primary focus on early postoperative pain.
Methods:
Participants were divided into two groups: cryopneumatic compression device group (CC group) and standard ice pack group (IP group). Patients in the CC Group (28 patients) received a cryopneumatic compression device (CTC-7, Daesung Maref) treatment, while patients in the IP group (28 patients) received standard ice pack cryotherapy postoperatively. All cryotherapy was applied three times (every 8 hours) per day for 20 minutes until discharge (postoperative day 7). Pain scores were assessed preoperatively and at 4, 7, and 14 days after surgery, and the primary outcome for analysis was pain at postoperative day 4 assessed using a visual analog scale (VAS). Other variables were opioid and rescue medication use, knee and thigh circumferences, postoperative drainage, and joint effusion quantified by a three-dimensional magnetic resonance imaging (MRI) reconstruction model.
Results:
The mean pain VAS score and difference in VAS relative to the preoperative measurements for postoperative day 4 were significantly lower in the CC group than in the IP group (p = 0.001 and p = 0.007, respectively). The sum of postoperative drainage and effusion quantified by MRI showed a significant reduction of postoperative effusion in the CC group compared to the IP group (p = 0.015). The average total rescue medication consumption was comparable between the two groups. Circumferential measurements at days 7 and 14 postoperatively relative to those at day 4 (index day) demonstrated no significant differences between the groups.
Conclusions
Compared to standard ice packs, application of cryopneumatic compression was associated with a significant reduction in VAS pain scores and joint effusion during the early postoperative period following ACL reconstruction.

OBJECTIVES: This study aims to investigate the risk of posttraumatic stress disorder (PTSD) and its related factors among firefighters dispatched to the rescue sites after the Great Japanese Earthquake in 2011. METHODS: Among 104 male firefighters dispatched to rescue sites after the Great Japanese Earthquake, 73 firefighters were assessed. The 73 firefighters completed questionnaires, which include general characteristics, an impact of event scale-revised Korean version (IES-R-K), a coping checklist, a scale of perceived social support, and a post-traumatic stress diagnostic scale (PDS). The data was analyzed to find factors related to PTSD risk. RESULTS: The mean value of age and work tenure in this study were 38.6 years (SD=5.7) and 11.6 years (SD=6.0), respectively. The number and rate of the PTSD high-risk group in dispatched firefighters in this study was 7 cases and 9.6% using IES-R-K, with an over 25-point cutoff score. The mean rank of tenure, 53.5 in the PTSD high-risk group (n=7), was significantly higher than that of 32.2 in the PTSD low-risk group (n=66). The mean rank of assessable support, 20.2 in the PTSD high-risk group was significantly lower than that of 38.7 in the PTSD low-risk group. In logistic analysis of model 1 including PDS in independent variables, were associated with being a PTSD high-risk group as in the following: higher PDS score (OR 2.18, 95% CI: 1.07~4.46), longer tenure (OR 3.42, 95% CI: 1.01~11.89), more using coping method (OR 1.35, 95% CI: 1.00~1.81), and lower perceptions of social support (OR 0.84, 95% CI: 0.72~0.97). In logistic analysis of model 2 without PDS in independent variables, more using coping method (OR 1.14, 95% CI: 1.01~1.28) and lower perceptions of social support (OR 0.95, 95% CI: 0.91~0.98) were associated with being a PTSD high-risk group. CONCLUSION: The PTSD high-risk group in dispatched firefighters indicated that their odds ratios were increased when they used more coping methods under specific stress conditions and had lower perceptions of social support. Therefore, for those, who might be dispatched to overseas, the psychological support approach should be considered to produce effective coping methods against traumatic events and to be aware of abundant resources for social support regarding the problem.

This study aimed to measure the variation in the levels of risk perception associated with various health risk factors. We analyzed the variables of psychological paradigms that may affect such risk perception levels. According to the perception survey results, the perception of the risk of medical malpractice appeared to be at the highest level compared to other risk factors. According to the analysis of differences in psychological paradigms of health risk factors between genders, the known extent of hazard that medical malpractice, medicines side effects, vaccination accidents, acquired immune deficiency syndrome (AIDS), and food poisoning was much high in female than in male. According to the evaluation of the severity of the risk to future generations, it appeared that women believed that vaccination accidents, AIDS, chronic diseases such as diabetes and hypertension, smoking, and drinking would have a greater effect on the risk to future generations than did men. The significance of this study is that the psychological paradigm affecting the perception level of health risk factors and the risk perceptions themselves have been analyzed by a survey of adults from the general population of Korea.

OBJECTIVES: There has been a growing concern about the possible carcinogenic effects of the electromagnetic radiofrequency fields emitted from mobile phones. The purpose of this study was to investigate the association between mobile phone use and the development of gliomas in Korea. METHODS: Our study methods were based on the International Interphone study that aimed to evaluate possible adverse effects of mobile phone use. This study included 285 histologically-confirmed Korean patients 15 to 69 years of age, with gliomas diagnosed between 2002 and 2007 in 9 hospitals. The 285 individually matched controls were healthy individuals that had their medical check-up in the same hospitals. Unconditional logistic regression was used to calculate the adjusted odds ratios (aORs) and 95% confidence intervals (CIs) for use of mobile phones. RESULTS: For the entire group, no significant relationship was investigated between gliomas and regular use of mobile phones, types of mobile phones, lifetime years of use, monthly service fee, and the other exposure indices. Analyses restricted to self-respondents showed similar results. For ipsilateral users, whose the body side for usual mobile phone use match the location of glioma, the aORs (95% CIs) for lifetime years of use and cumulative hours of use were 1.25 (0.55 to 2.88) and 1.77 (0.32 to 1.84), respectively. However, the contralateral users showed slightly lower risk than ipsilateral users. CONCLUSIONS: Our results do not support the hypothesis that the use of mobile phones increases the risk of glioma; however, we found a non-significant increase in risk among ipsilateral users. These findings suggest further evaluation for glioma risk among long-term mobile phone users.
