Does intraoperative transfusion during total knee arthroplasty reduce the need for transfusion after surgery?: A preliminary retrospective cohort study.

OBJECTIVES: After total knee arthroplasty (TKA), many patients experience anemia due to blood loss. To prevent postoperative anemia and allogeneic blood transfusion after TKA, we used prophylactic allogeneic or autologous blood transfusion intraoperatively. This study evaluated the effects of prophylactic transfusion during TKA. MATERIALS AND METHODS: This retrospective cohort study included 579 patients receiving scheduled unilateral TKA. We allocated the patients into three groups, the prophylactic allogeneic transfusion (Group AL), prophylactic autologous transfusion (Group AT), and no prophylactic transfusion with intra-articular tranexamic acid administration (GroupC) groups. After propensity score matching, we compared the rate of postoperative allogeneic blood transfusions until three days after TKA, postoperative hemoglobin and hematocrit levels until four days after TKA, and the side effects in each groups. RESULTS: The postoperative allogeneic blood transfusion rates were statistically higher in group AL and AT than in group C (18.2% and, 18.9% vs 2.3%, respectively; P<0.000). The postoperative hemoglobin and hematocrit levels were statistically lower in group Auto than in group C (P<0.0001), but the levels in group AL were not different from those of group C (P=0.493 vs. P=0.384 respectively). In addition, the side effects were statistically higher in group AL and AT than in group C. CONCLUSION: Prophylactic intra-operative transfusions did not reduce the rates of allogeneic transfusions and produced more side effects and hypotension after surgery than intra-articular tranexamic acid administration with no prophylactic transfusion in patients undergoing TKAs.

Comparison of the Usefulness of ComputerAssisted Three-Dimensional Analysis and WeightBearing Radiographs in Ankle Osteoarthritis

Background@#To evaluate the degree of deformation in patients with ankle osteoarthritis (OA), it is essential to measure the threedimensional (3D), in other words, stereoscopic alignment of the ankle, subtalar, and foot arches. Generally, measurement of radiological parameters use two-dimensional (2D) anteroposterior and lateral radiographs in a weight-bearing state; however, computeraided 3D analysis (Disior) using weight-bearing cone-beam computed tomography (CBCT) has recently been introduced. @*Methods@#In this study, we compared the 2D human radiographic method with a stereoscopic image in patients with ankle arthritis. We enrolled 57 patients diagnosed with OA (28 left and 29 right) and obtained both standing radiographs and weight-bearing CBCT. Patients were divided by the Takakura stage. The interclass correlation coefficient (ICC) for each result was confirmed. @*Results@#On the ICC between 2D radiographs and 3D analysis, the tibiotalar surface angle and lateral talo-1st metatarsal angle showed a good ICC grade (> 0.6), while other parameters did not have significant ICC results. Three-dimension was superior to radiographs in terms of statistical significance. @*Conclusions@#We demonstrated that 2D and stereoscopic images are useful for the diagnosis of OA. Our study also confirmed that the radiographic features affected by ankle OA varied. However, according to the results, the typical radiography is not sufficient to diagnose and determine a treatment plan for ankle OA. Therefore, the method of using 3D images should be considered.

Current Health Data Standardization Project and Future Directions to Ensure Interoperability in Korea / 대한의료정보학회지

Objectives@#The need for interoperability at the national level was highlighted in Korea, leading to a consensus on the importance of establishing national standards that align with international technological standards and reflect contemporary needs. This article aims to share insights into the background of the recent national health data standardization policy, the activities of the Health Data Standardization Taskforce, and the future direction of health data standardization in Korea. @*Methods@#To ensure health data interoperability, the Health Data Standardization Taskforce was jointly organized by the public and private sectors in December 2022. The taskforce operated three working groups. It reviewed international trends in interoperability standardization, assessed the current status of health data standardization, discussed its vision, mission, and strategies, engaged in short-term standardization activities, and established a governance system for standardization. @*Results@#On September 15, 2023, the notice of “Health Data Terminology and Transmission Standards” in Korea was thoroughly revised to improve the exchange of health information between information systems and ensure interoperability. This notice includes the Korea Core Data for Interoperability (KR CDI) and the Korea Core Data Transmission Standard (HL7 FHIR KR Core), which are outcomes of the taskforce’s efforts. Additionally, to reinforce the standardized governance system, the Health-Data Standardization Promotion Committee was established. @*Conclusions@#Active interest and support from medical informatics experts are needed for the development and widespread adoption of health data standards in Korea.

Association between Possible Sarcopenia and Depressive Symptoms in Korean Older Adults: Results from the Korea National Health and Nutrition Examination Survey in 2018 / 가정의학회지

Background@#Despite increased clinical and research interest in sarcopenia, even in Asia, not much is known about the association between sarcopenia and depressive symptoms. Sarcopenia and depressive symptoms are associated with several health problems in older adults; therefore, we investigated the association between sarcopenia and depression in Korean older adults. @*Methods@#The study sample included 1,929 participants aged over 60 years (44.6% men; mean age, 69.7 years) from nationally representative data of the 2018 Korea National Health and Nutrition Examination survey. Possible sarcopenia was defined according to the diagnostic algorithm of the Asian Working Group for Sarcopenia 2019; however, we measured only hand-grip strength (kg) in this study. Patient Health Questionnaire-9 was used for screening for symptoms of depression. A cross-sectional analysis was used to examine the relationship between possible sarcopenia and depressive symptoms. @*Results@#Possible sarcopenia and depressive symptoms were identified in 538 (27.9%) and 97 (5.0%) participants, respectively. After adjusting for age, sex, and other potential covariates, possible sarcopenia was positively associated with higher odds of depressive symptoms (odds ratio, 2.06; 95% confidence interval, 1.36–3.11; P<0.001). @*Conclusion@#Possible sarcopenia was significantly associated with depressive symptoms in Korean older adults. Early interventions for possible sarcopenia and depressive symptoms in routine clinical practice could help Korean older adults to have healthy aging. Future studies are required to explore any causal relationship between possible sarcopenia and depressive symptoms in Korean older adults.

Evaluating the Landscape of Personal Health Records in Korea: Results of the National Health Informatization Survey / 대한의료정보학회지

Objectives@#This study examined the adoption and utilization of personal health records (PHR) across Korean medical institutions using data from the 2020 National Health and Medical Informatization Survey. @*Methods@#Spearheaded by the Ministry of Health and Welfare and prominent academic societies, this study surveyed PHR utilization in 574 medical institutions. @*Results@#Among these institutions, 84.9% (487 hospitals) maintained medical portals. However, just 14.1% (81 hospitals) had web-based or mobile PHRs, with 66.7% (28 of 42) of tertiary care hospitals adopting them. Tertiary hospitals led in PHR services: 87.8% offered certification issuance, 51.2% provided educational information, 63.4% supported online payment, and 95.1% managed appointment reservations. In contrast, general and smaller hospitals had lower rates. Online medical information viewing was prominent in tertiary hospitals (64.3%). Most patients accessed test results via PHRs, but other data types were less frequent, and only a few allowed downloads. Despite the widespread access to medical data through PHRs, integration with wearables and biometric data transfers to electronic medical records remained low, with limited plans for expansion in the coming three years. @*Conclusions@#Approximately two-thirds of the surveyed medical institutions provided PHRs, but hospitals and clinics in charge of community care had very limited PHR implementation. Government-led leadership is required to invigorate the use of PHRs in medical institutions.

Mitochondria in reproduction / 대한생식의학회지

In reproduction, mitochondria produce bioenergy, help to synthesize biomolecules, and support the ovaries, oogenesis, and preimplantation embryos, thereby facilitating healthy live births. However, the regulatory mechanism of mitochondria in oocytes and embryos during oogenesis and embryo development has not been clearly elucidated. The functional activity of mitochondria is crucial for determining the quality of oocytes and embryos; therefore, the underlying mechanism must be better understood. In this review, we summarize the specific role of mitochondria in reproduction in oocytes and embryos. We also briefly discuss the recovery of mitochondrial function in gametes and zygotes. First, we introduce the general characteristics of mitochondria in cells, including their roles in adenosine triphosphate and reactive oxygen species production, calcium homeostasis, and programmed cell death. Second, we present the unique characteristics of mitochondria in female reproduction, covering the bottleneck theory, mitochondrial shape, and mitochondrial metabolic pathways during oogenesis and preimplantation embryo development. Mitochondrial dysfunction is associated with ovarian aging, a diminished ovarian reserve, a poor ovarian response, and several reproduction problems in gametes and zygotes, such as aneuploidy and genetic disorders. Finally, we briefly describe which factors are involved in mitochondrial dysfunction and how mitochondrial function can be recovered in reproduction. We hope to provide a new viewpoint regarding factors that can overcome mitochondrial dysfunction in the field of reproductive medicine.

Medical Humanities Course Development Experience in Medical School / 계명의대학술지

Ethics is the basis and conditions necessary for humans to live together, so all education is based on an ethical consciousness. However, educators should reflect on the fact that these functions of education are not working well in real life. In particular, the reason why medicine should not let go of the value of living together in a community is that the human dignity stipulated by the constitution of each country should not be violated by anything. Therefore, the medical college curriculum needs speculative theories and discourses that were discussed in traditional medical education to understand the purpose of their existence in the medical-philosophy relationship, strengthen their sense of ethics as a doctor, and embody roles and responsibilities for the community. In this way, 10 educational experts in medicine, philosophy, (medical) education, psychology, and social welfare at the university and the medical school in Daegu discussed and developed medical humanities subjects and conducted lectures. The education method was conducted through lectures, discussions, and presentations, and was evaluated by attendance and attitude, peer evaluation, and portfolio. In addition to theoretical knowledge about community spirit, the importance of discussion and communication and cooperation were induced in the process. Faculty members participated together to reflect on the nature of education based on the results of a semester-long study of medical humanities subjects and consider the direction that medical education should pursue in the future.

Unusual Complex Apocrine Tumor Consisting of Syringocystadenoma Papilliferum and Apocrine Hidrocystoma within a Single Lesion: A Case Report

Syringocystadenoma papilliferum (SCAP) and apocrine hidrocystoma (AH) are benign apocrine neoplasms that usually occur separately. SCAP arises predominantly in head and neck, while AH typically develop in periorbital area. We report a case of a 68-year-old male with an asymptomatic erythematous papulonodule that occurred on his back 3 years ago. Histologic examination showed cystic invagination extending from the epidermis into the dermis with some papillary projections. The invaginated portion was lined by epithelial bilayer composed of cuboidal and columnar cells, and decapitation secretion was observed in the inner epithelial layer. In the deep dermis, multiple cystic spaces with variable sizes were observed, and these cysts also presented double layers of the epithelium and decapitation secretion.According to such histologic features, the coexistence of SCAP and AH within a single lesion was demonstrated. The patient was recommended to completely remove the remaining lesion after punch biopsy, but he refused further surgical management. Herein, we report an unusual case of complex apocrine tumor with a rare composition in an atypical site.

Outcomes of Angular Stable Locking System in Femoral Diaphyseal Fractures of Elderly Patients:A Multicenter Comparative Study

Background@#The angular stable locking system (ASLS) was developed to provide additional stability to the distal interlocking screw of the intramedullary (IM) nail. Effects of ASLS on the treatment of femoral diaphyseal fractures in the elderly remain unknown. The aim of this study was to compare radiological outcomes of IM nailing using ASLS screws to IM nails with conventional interlocking screws in elderly patients with femoral shaft fractures. @*Methods@#A multicenter retrospective review of 129 patients (average age, 73.5 years; 98 women and 31 men) aged 65 years or older who underwent IM nail fixation for femoral diaphyseal fractures (AO/Orthopaedic Trauma Association [OTA] classification 32) was conducted. Demographic information of patients, fracture site (subtrochanteric or shaft), fracture type (traumatic or atypical), and AO/OTA fracture classification were investigated. Reduction status was evaluated by postoperative plain radiography. Presence of union and time to union were evaluated through serial plain radiograph follow-up. Reoperation due to nonunion or implant failure was also evaluated. @*Results@#ASLS was used in 65 patients (50.3%). A total of 118 patients (91.5%) achieved union without additional surgery and the mean union time was 31.8 ± 13.0 weeks. In terms of reduction status, angulation was greater in the group using ASLS. There were no statistically significant differences of union rate, time to union, and reoperation rate according to the use of ASLS (p > 0.05). There was no difference in the outcomes according to the use of ASLS even when the analysis was divided in terms of fracture site or fracture type (p > 0.05). In further subgroup analysis, only the traumatic subtrochanteric area group showed statistically significantly shorter time to union when ASLS was used (p = 0.038). @*Conclusions@#In geriatric patients with femoral diaphyseal fractures, the use of ASLS was not considered to have a significant effect on fracture healing. Fracture healing seemed to be more affected by surgical techniques such as minimizing the gap and fracture characteristics such as atypical femoral fractures, rather than implants.

Phloretin Ameliorates Succinate-Induced Liver Fibrosis by Regulating Hepatic Stellate Cells

Background@#Hepatic stellate cells (HSCs) are the major cells which play a pivotal role in liver fibrosis. During injury, extracellular stimulators can induce HSCs transdifferentiated into active form. Phloretin showed its ability to protect the liver from injury, so in this research we would like to investigate the effect of phloretin on succinate-induced HSCs activation in vitro and liver fibrosis in vivo study. @*Methods@#In in vitro, succinate was used to induce HSCs activation, and then the effect of phloretin on activated HSCs was examined. In in vivo, succinate was used to generated liver fibrosis in mouse and phloretin co-treated to check its protection on the liver. @*Results@#Phloretin can reduce the increase of fibrogenic markers and inhibits the proliferation, migration, and contraction caused by succinate in in vitro experiments. Moreover, an upregulation of proteins associated with aerobic glycolysis occurred during the activation of HSCs, which was attenuated by phloretin treatment. In in vivo experiments, intraperitoneal injection of phloretin decreased expression of fibrotic and glycolytic markers in the livers of mice with sodium succinate diet-induced liver fibrosis. These results suggest that aerobic glycolysis plays critical role in activation of HSCs and succinate can induce liver fibrosis in mice, whereas phloretin has therapeutic potential for treating hepatic fibrosis. @*Conclusion@#Intraperitoneal injection of phloretin attenuated succinate-induced hepatic fibrosis and alleviates the succinate-induced HSCs activation.

Diarylpropionitrile inhibits melanogenesis via protein kinase A/cAMP-response element-binding protein/microphthalmiaassociated transcription factor signaling pathway in α-MSHstimulated B16F10 melanoma cells

Diarylpropionitrile (DPN), a selective agonist for estrogen receptor β(ERβ), has been reported to regulate various hormonal responses through activation of ERβ in tissues including the mammary gland and brain. However, the effect of DPN on melanogenesis independent of ERβ has not been studied. The aim of this study is to examine the possibility of anti-melanogenic effect of DPN and its underlying mechanism. Melanin contents and cellular tyrosinase activity assay indicated that DPN inhibited melanin biosynthesis in alpha-melanocyte stimulating hormonestimulated B16F10 melanoma cell line. However, DPN had no direct influence on in vitro tyrosinase catalytic activity. On the other hand, 17β-estradiol had no effect on inhibition of melanogenesis, suggesting that the DPN-mediated suppression of melanin production was not related with estrogen signaling pathway. Immunoblotting analysis showed that DPN down-regulated the expression of microphthalmiaassociated transcription factor (MITF), a central transcription factor of melanogenesis and its down-stream genes including tyrosinase, tyrosinase-related protein (TRP)-1, and TRP-2. Also, DPN attenuated the phosphorylation of protein kinase A (PKA) and cAMP-response element-binding protein (CREB). Additionally, DPN suppressed the melanin synthesis in UVB-irradiated HaCaT conditioned media culture system suggesting that DPN has potential as an anti-melanogenic activity in physiological conditions. Collectively, our data show that DPN inhibits melanogenesis via downregulation of PKA/CREB/MITF signaling pathway.

Approach to Hospitalized Patients with Fever and Skin Eruption: A Retrospective Analysis of Clinical Features / 대한피부과학회지

Background@#Fever and skin eruption are common manifestations in patients; however, assessing them can be challenging because of the wide range of differential diagnosis. @*Objective@#We aimed to obtain tips that could assist in differential diagnoses in patients with fever and skin eruption through the analysis of clinical features. @*Methods@#Medical records of hospitalized patients who had fever and skin eruption were examined from January 2010 to December 2019. @*Results@#The patients of the adverse drug reaction group were older (p=0.024), and they had underlying diseases (p＜0.001), whole body skin eruption (p=0.018), elevated alanine aminotransferase (p=0.027). The autoimmune disease group was associated with longer total fever and skin eruption duration (p=0.049, 0.037), leukocytosis (p=0.015), and neutrophilia (p=0.006). Infectious erythema group was associated with targetoid lesions (p=0.003). @*Conclusion@#Clinicians should examine patients with fever and skin eruption, considering that there may be various causes. This can be assisted by delicate skin exam and laboratory tests.

Polo-like kinase 4 as a potential predictive biomarker of chemoradioresistance in locally advanced rectal cancer

Background@#Polo-like kinase 4 (PLK4) is a serine/threonine protein kinase located in the centriole of the chromosome during the cell cycle. PLK4 overexpression has been described in a variety of many common human epithelial tumors. Conversely, PLK4 acts as a haploinsufficient tumor suppressor in some situations, highlighting the importance of strict regulation of PLK4 expression, activity, and function. Meanwhile, the importance of chemoradiation resistance in rectal cancer is being emphasized more than ever. We aimed to analyze PLK4 expression and the tumor regression grade (TRG) in patients with rectal cancer, treated with chemoradiotherapy (CRT). @*Methods@#A retrospective study was conducted on 102 patients with rectal cancer who received preoperative CRT. Immunohistochemistry for PLK4 in paraffin-embedded tissue was performed from the biopsy and surgical specimens. @*Results@#We found significant association between high expression of PLK4 and poor response to neoadjuvant CRT (according to both Mandard and The Korean Society of Pathologists TRG systems) in the pre-CRT specimens. Other clinicopathologic parameters did not reveal any correlation with PLK4 expression. @*Conclusions@#This study revealed an association between high expression of PLK4 in the pre-CRT specimens and TRG. Our results indicated that PLK4 could potentially be a new predictor for CRT effect in patients with rectal cancer.

Efficacy of lower dose pirfenidone for idiopathic pulmonary fibrosis in real practice: a retrospective cohort study

Background/Aims@#Pirfenidone slows the progression of idiopathic pulmonary fibrosis (IPF). We investigated its efficacy and safety in terms of dose and disease severity in real-world patients with IPF. @*Methods@#This multicenter retrospective cohort study investigated 338 patients treated with pirfenidone between July 2012 and March 2018. Demographics, pulmonary function, mortality, and pirfenidone-related adverse events were also investigated. Efficacy was analyzed according to pirfenidone dose and disease severity using linear mixed-effects models to assess the annual decline rate of forced vital capacity (FVC) and diffusing capacity of the lungs for carbon monoxide (DLCO). @*Results@#The mean %FVCpredicted and %DLCOpredicted values were 72.6% ± 13.1% and 61.4% ± 17.9%, respectively. The mean duration of pirfenidone treatment was 16.1 ± 9.0 months. In the standard dose (1,800 mg/day) group, the mean %FVCpredicted was −6.56% (95% confidence interval [CI], −9.26 to −3.87) per year before, but −4.43% (95% CI, −5.87 to −3.00) per year after treatment with pirfenidone. In the non-standard lower dose group, the mean %FVCpredicted was −4.96% (95% CI, −6.82 to −3.09) per year before, but −1.79% (95% CI, −2.75 to −0.83) per year after treatment with pirfenidone. The FVC decline rate was significantly reduced, regardless of the Gender-Age-Physiology (GAP) stage. Adverse events and mortality were similar across dose groups; however, they were more frequent in GAP stages II–III than in the stage I group. @*Conclusions@#The effect of pirfenidone on reducing disease progression of IPF persisted even with a consistently lower dose of pirfenidone.

The Correlation Between Facial Proportion Measurement and the Beauty Satisfaction in College Students / 계명의대학술지

In the modern era, the standards and expectations for the shape and beauty of the face are increasing. Therefore, we measured the facial structure and its proportions in Koreans, and to find out the correlation between these results and beauty satisfaction. A questionnaire survey and facial structure measurement were conducted on 85 college students about their beauty satisfaction. The vertical height of the face was 206.0 ± 35.5 mm, and the vertical ratio was 1:1:1. The width of the face was 168.1 ± 30.4 mm, and when it was divided into 5 parts, the middle part was the widest. Dimples and dark circles were found in 22 (25.9%) and 51 (60.0%), respectively, and eye length and nose height nose were 12.6 ± 2.7 mm and 22.8 ± 9.5 mm, respectively. Beauty satisfaction was on average 28.7 ± 5.9 out of a total of 50 points, inversely proportional to the length of the face (r = -0.235), and was proportional to the width of the nose (r = 0.298). And beauty satisfaction was related to skin condition, but it was not statistically significant. It can be used in various ways as basic data on the shape and proportion of Korean faces obtained through this study, and by comparing this with beauty satisfaction, it is thought that false recognition and stress according to the individual's aesthetic standards can be reduced.

Analysis of the Cancer Genome Atlas Data to Determine the Prognostic Value of GABPB1L and TERT in Glioblastoma / 계명의대학술지

Glioblastoma multiforme (GBM) is the most lethal type of brain tumor and its prognosis was extremely poor. Here, we studied the clinical and prognostic value of telomerase reverse transcriptase (TERT) and GA Binding Protein Transcription Factor Subunit Beta 1 longer (GABPB1L) mRNA expression in GBM by using open big data. In total 152 GBM patients, gene expressions were downloaded from the Cancer Genome Atlas (TCGA) data and its values were statistically analyzed. TCGA data showed that GABPB1L mRNA expression levels did not correlate with those of TERT mRNA (r = -0.027, p = 0.744). GABPB1L and TERT expressions in GBM were associated with subtype by gene expression. GABPB1L (562.7 ± 76.8 days vs. 479.1 ± 5.8 days, p = 0.401) and TERT (468.1 ± 43.6 days vs. 565.3 ± 75.8 days, p = 0.403) expression was not associated with GBM prognosis. However, disease-free survival was tended to be different in GBM patients according to TERT and GABPB1L expressions though it did not get statistical significance (2122.6 ± 160.2 days vs. 1381.1 ± 244.0 days, p = 0.072). These genes may contribute to the GBM pathogenesis and its further study should be performed in GBM patients and cell lines.

Review of National-Level Personal Health Records in Advanced Countries / 대한의료정보학회지

Objectives@#This review article examines international examples of personal health records (PHRs) in advanced countries and discusses the implications of these examples for the establishment and utilization of PHRs in South Korea. @*Methods@#This article synthesized PHR case reports of Organization for Economic Co-operation and Development (OECD) member countries, the Global Digital Health Partnership website on PHRs, and patient portals of individual countries to review the status of PHR services. The concept and significance of PHRs were also discussed with respect to PHR utilization status in European Union and OECD countries. @*Results@#A review of international PHR services showed that the countries shared common points regarding the establishment of Electronic Health Records and national health information infrastructure. In addition, the countries provided services centered on primary healthcare institutions and public hospitals. However, promoting more positive participation and increasing the PHR acceptance rate requires workflow integration, including Electronic Medical Records, the provision of incentives, and the preparation of a supportive legal framework. @*Conclusions@#South Korea is also conducting a national-level PHR project. Since the scope of PHRs is extensive and a wide range of PHR services must be connected, an extensive trial-and-error process will be necessary. A long-term strategy should be prepared, and necessary resources should be secured to establish national-level PHRs.
