Citation Analysis of the Journal of Bone Metabolism from Korean Citation Index, Web of Science, and Scopus

Background@#Nine years have passed since the Journal of Bone Metabolism (JBM) was launched as an English journal in 2012; it was finally included in Scopus in January 2019. Therefore, this study aimed to provide evidence of increased international recognition based on journal metrics and reflect on its efforts to be recognized as a top-notch journal. @*Methods@#Databases, such as the Web of Science (WoS), Scopus, Korean Citation Index (KCI), and citation indicators, including the impact factor (IF) and SCImago journal rank (SJR) were reviewed and calculated according to years, and the results were drawn. Furthermore, country-wise contributions and top-cited articles were also investigated. @*Results@#The JBM 2020 IF was 2.17 in the WoS. The 2020 SJR in Scopus was 0.334, with a ranking of 165/219 (75.3%) in the Endocrinology, Diabetes, and Metabolism category. The 2020 KCI was 0.42. Of 263 articles, 260 were citable (98.9%), and of 176 original articles, 15 (8.5%) were supported by research grants. The total citation of JBM has increased from 16 in 2014 to 141 in 2020; however, its KCI remained stationary from 0.29 in 2015 to 0.42 in 2020. @*Conclusions@#Currently, JBM is increasingly cited by international researchers than Korean researchers, indicating that the journal’s content is valued at an international level. Its inclusion in PubMed Central appears to have increased its international relevance; however, publishing English-only articles may hinder its use domestically. Therefore, efforts should be made to increase citation rates and enhance domestic readership.

Assessment of Korea's Orthopedic Research Activities in the Top 15 Orthopedic Journals, 2008–2017

BACKGROUND: Bibliometrics is increasingly used to assess the quantity and quality of scientific research output in many research fields worldwide. This study aims to update Korea's worldwide research productivity in the field of orthopedics using bibliometric methods and to provide Korean surgeons and researchers with insights into such research. METHODS: Articles published in the top 15 orthopedic journals between 2008 and 2017 were retrieved using the Web of Science. The number of articles, citations and h-index (Hirsch index), funding sources, institutions, and journal patterns were analyzed. RESULTS: Of the total 39,494 articles, Korea's contribution accounted for 5.6% (2,161 articles), ranking fifth in the world in the number of publications. Korea ranked sixth (with 29,456) for total citations worldwide but ranked 17th (13.64) in terms of average citation per item and 14th (55) in terms of h-index. Korea showed the most prolific productivity in the field of sports medicine and arthroscopy. The institution that produced the highest number of publications was Seoul National University (n = 386, 17.9%). CONCLUSIONS: Orthopedic research in South Korea demonstrated high productivity in terms of the number of publications in high-quality journals between 2008 and 2017. However, total citations and average citations per article were still relatively low. Efforts should be made to increase citation rates for further improvement in research productivity in the field of orthopedics.

Clinical application of liver stiffness measurement for assessing the risk of hepatocellular carcinoma

The most significant risk factor for hepatocellular carcinoma (HCC) is the presence of cirrhosis or advanced fibrosis of the liver. Liver biopsy was traditionally considered the gold standard for assessing the liver fibrosis burden. Recently, non-invasive methods, particularly transient elastography (TE), have proven effective at measuring fibrosis and determining cirrhosis. Clinical application of TE ranges from measuring fibrosis to predicting long-term prognosis and treatment response. Here, we focus on recent studies on the prognostic value of TE for predicting HCC.

Relationship between History of Pregnancies and Bone Mineral Density / 대한골다공증학회지

OBJECTIVES: We investigated bone mineral density (BMD) in women as this is related to a history of previous pregnancies and miscarriage and according to age. MATERIALS & METHODS: We performed retrospective study on 1,043 women who had their BMD in a university hospital. We analyzed the BMD and the previous obstetric history according to age and the clinical characteristics. RESULTS: The mean age of the study subjects was 56.7+/-5.9 years. The gravida based on ages is not statistically related to the BMD (P-value=0.578), except for the spine BMD (P-value<0.001). CONCLUSIONS: Obstetric history of previous child birth and/or miscarriages, did not effect on bone mineral density, but further prospective multicenter study about obstetric history should be considered for prevention of osteoporosis before menopause.

Complication of Crohn's disease on the vulva treated as a Bartholin's gland abscess: A case report / 대한산부인과학회지

Crohn's disease is known as regional enteritis. Extra-intestinal complications of Crohn's disease are relatively common. Extra-intestinal manifestations include skin ulcers, erythema nodosum, and arthritis. Even cases of the vulva involvement by Crohn's disease have been reported. Gynecologists did not usually consider Crohn's disease as a complication involving the vulva; gynecologists diagnose Bartholin's gland abscess first. Gynecologists have fully to consider history taking about disease characteristics. We reported recto-vulva fistula complicated by Crohn's disease and it is side effects after marsupialization operation.

Initial nutritional status of stomach cancer patients

The purpose of this study is to investigate initial nutritional status of stomach cancer patients. The study subjects were 88 patients with stomach cancer admitted at Kosin University Gospel Hospital in Busan. We assessed the initial nutritional status by anthropometric, biochemical and dietary intake data along with subjective global assessment(SGA). The results are as follows. 1. The mean age, weight, height, triceps skinfold thickness, mid arm circumference, and mid arm muscle circumference of the subjects were 55.9+/-11.0years, 60.0+/-9.8kg, 162.4+/-8.5cm, 10.9+/-5.7mm, 26.8+/-3.8cm, and 23.4+/-3.5cm respectively. The mean body mass index was within the normal range, with 22.7+/-2.8kg/m2, while 15.4% of the patients was underweight. The result shows that body fat mass and body protein mass of the patients with stomach cancer were decreased. 2. The mean biochemical data of the subjects were 4.0+/-0.5g/dl for albumin, 174.7+/-41.9mg/dl for cholesterol, 107.6+/-57.2mg/dl for triglyceride, 92.1microgram/dl for Zn, 297.0+/-103.1mg/dl for transferrin, 1980.0+/-0.8mm3 for total lymphocyte count. 3. Daily energy intake was 1997.8+/-579.3kcal. And the ratio of carbohydrate, protein, and lipid to energy intake was 72:14:14. 4. The patients were divided into three groups according to SGA performed by an observer. Group A(well nourished) was 55.7% with 49 patients, Group B(moderately malnourished) was 22.7 % with 20 patients, and Group C(severely malnourished) was 21.6 % with 19 patients. The three groups showed a significant difference in body weight(p<0.01), 1 month weight loss %(p<0.001), 6 months weight loss %(p<0.001), body mass index(p<0.01), and mid arm circumference(p<0.05), albumin(p<0.01), energy intake(p<0.05) as well as carbohydrate intake(p<0.05). From these results, it may be concluded that SGA can be used as a nutrition screening tool, and comprehensive nutrition assessment is desirable for those malnourished.

Abnormalities of Liver Function during Total Parenteral Nutrition (TPN): Alteration of Serum Liver Enzyme during Short-term TPN

PURPOSE: TPN has been widely used to treat nutritional depletion since the late 1960s. However, many metabolic complications may occur as a result of parenteral feeding. Among these, hepatic complications has received increasing attention. A retrospective review of liver function abnormalities in adult patients who underwent TPN was done to determine the frequency and magnitude of the abnormalities in a liver function test. METHODS: From January 2001 to Jun 2001, 160 adult patient receiving TPN were reviewed. Of these, 111 had a malignant disease and 49 had a benign disease. The duration of TPN therapy ranged from 5 days to 52 days, with a mean duration of 14 days. Abnormalities of liver function test were defined as a value greater than the upper normal limit. Forty cases of gastric cancer were analyzed to determine the risk factors that contribute to abnormal liver function in individual patients receiving TPN. RESULTS: Abnormalities of the liver function test appeared after 6~7 days of therapy. Increases in the ALP levels were noted in 34 out of 93 patients (37.6%), in the AST levels in 42 out of 116 patients (36.2%), in the ALT levels in 54 out of 125 patients (43.2%), in the LDH levels in 20 out of 72 patients (27.8%), in the gamma-GTP levels in 44 out of 81 patients (54.3%), and in the bilirubin levels in 30 out of 126 patients (23.8%). The serum ALP level rose to 1.6 times upper the limit of normal; AST, 1.7 times; ALT, 2.0 times; LDH, 1.2 times; gamma-GTP, 2.4 times; bilirubin, 2.4 times. gamma-GTP value was most sensitive. In 40 gastric cancers, factors as age, the amount of TPN solution, the duration of TPN, intraoperative chemotherapy, transfusion, and postoperative infection were investigated. However, no association with TPN-associated liver function abnormalities was found. CONCLUSION: The incidences of an abnormal liver function during TPN were 23.8~54.3%. However, the liver function abnormalities that developed during short term-TPN were reversible and not serious.
