This study aims to correct the Chinese characters of 普救女館 (Po Goo Nyo Goan) and its Korean pronunciation by re-examining the circumstances around the establishment of this hospital, and to discover its naming principle which is associated with the Confucian political philosophy of the Joseon Dynasty. Although 普救女館 is the first modern women's hospital in Korea, most historical studies of this institute have been conducted on limited documents and records. Many published studies use the incorrect names in many ways, so the correct name of the hospital is still in confusion.普救女館, however, was named with four or five of the Chinese characters given by the Joseon government (King Gojong (高宗)) at the time of its establishment. The Joseon government gave the name of Seonnyeoboguwon (善女普救院) to the first modern women's hospital established by Mary Scranton, the name of which was changed to 普救女館.Some records left by the female missionary doctors who worked in 普救女館 show the romanization and meaning of the name of the hospital. The romanization of 普救女館 clarified the Korean pronunciation of “女 (nyeo)” at that time. English translation name of the hospital has always shown that the place provided “extensive” medical treatment to women. It proves the fact that the first Chinese character of the name is “普”, not “保” which is expressed in many documents today.The hospital was named according to Confucian ideals just like the other modern hospitals established around the same time, such as Jejungwon (濟衆院), Gwangjewon (廣濟院), Gwanghyeyeowon (廣惠女院). The Joseon government commonly used similar Chinese characters during the naming of these hospitals, characters that imply the ideal of the good Confucian king's favor for many people of Joseon. 普救女館 was unique in having the character “館(gwan)” in its name, not “院(won)” as in other hospitals. It seems to stem from the characteristic of “women's hospital.” Po Gu Nyo Goan, the unprecedented women's hospital, was probably imagined as a hospitable accommodation where women provided kindness to people in need. This may have been the reason why “館”, which has the meaning of accommodation, was chosen instead of “院” that primarily meant medical facilities.Correcting the name of 普救女館 helps to eliminate the confusion in current historiography and to promote the understanding of the historical significance of this hospital.

Recently, atypical femoral fractures (AFFs) have been found in patients who were prescribed bisphosphonate to prevent osteoporotic fractures. Although the occurrence of AFF is rare, there are some concerns, such as a higher risk of delayed or non-union of AFF. This paper reviews the treatment of AFF and suggests some considerations during surgery.

Background: The Harris-Galante (HG) prosthesis is a first-generation, cementless total hip arthroplasty (THA) prosthesis. Considering the recent increase in the demand for THA in young patients and their life expectancy, a study with a follow-up duration of longer than 20 years in a young population is needed. Therefore, we evaluated the long-term clinical and radiographic results after cementless THA using the HG prosthesis in patients younger than 50 years. Methods: A total of 61 THAs performed using the HG with a minimum follow-up of 10 years were included. There were 38 men and 11 women with an average age of 46 years and the mean follow-up duration was 22 years. Clinical evaluation included modified Harris Hip Score (HHS) and radiographic analysis consisted of cup inclination, anteversion angle, component stability, osteolysis, liner wear rate, wear-through, liner dissociation, and heterotopic ossification. Complications included recurrent dislocation, periprosthetic femoral fracture, and periprosthetic joint infection. Survivorship analysis included cup and stem revision for aseptic loosening, as well as any revision. Results: The HHS improved from 46.5 preoperatively to 81.8 postoperatively (p < 0.001). The average linear wear rate was 0.36 mm/yr. A total of 34 hips (56%) were revised: stem revision in 10 (16.4%), cup revision in 9 (14.8%), exchange limited to bearing surface in 8 (13.1%), and revision of all components in 7 (11.5%). Estimated survivorship at 34 years postoperatively was 90.9% for cup revision for aseptic loosening, 80.5% for stem revision for aseptic loosening, and 22.1% for any revision. Conclusions THA using the HG prosthesis showed satisfactory estimated survivorship of the acetabular and femoral components at 34 years postoperatively with good clinical outcomes. Bearing-related problems, such as osteolysis and liner dissociation, accounted for 56% of revision operations and were concerns in patients younger than 50 years.

OBJECTIVE: Enteroviruses are major causes of aseptic meningitis in children. This study aimed to describe the clinical manifestations of enteroviral meningitis according to the presence of cerebrospinal fluid (CSF) pleocytosis, and to investigate the factors influencing the CSF pleocytosis in children with this condition. METHODS: Eighty children with enteroviral meningitis treated at Soonchunhyang University Hospitals in Seoul and Bucheon between July 2012 and August 2013 were enrolled. The patients were diagnosed by reverse transcription-polymerase chain reaction (RT-PCR), and the clinical variables were compared according to the presence of CSF pleocytosis. RESULTS: Of the 80 patients, 54 (67.5%) and 26 (32.5%) patients had and did not have CSF pleocytosis, respectively. Forty-eight (60%) patients were male, and the median age was 63 months (range, 2 to 192 months). Seventy-six (95%), 67 (83.7%), 51 (63.7), and 2 (2.5%) patients presented with fever, headache, vomiting, and seizure, respectively. Increased CSF protein and pressure were associated with CSF pleocytosis. However, age, peripheral white blood cell count, C-reactive protein, CSF glucose, CSF/serum glucose ratio, and onset-puncture time interval were not associated with the presence of CSF pleocytosis. CONCLUSION: This study demonstrated a high proportion of non-pleocytic enteroviral meningitis in children, and identified several clinical manifestations that were associated with CSF pleocytosis. The findings of this study may help us better understand the characteristics of the disease and facilitate early diagnosis and treatment of enteroviral meningitis. During the outbreak seasons of enteroviral meningitis, the importance of continuous surveillance of enteroviruses and rapid RT-PCR testing should be emphasized.

The biomechanics study of the hip is aims to understand and explore the dynamic principles of weight transfer through the hip joint. This basic science knowledge can be applied in a variety of areas, including degenerative joint diseases and hip replacement arthroplasty. In particular, understanding of the biomechanics of the hip has led to the development of materials, design and fixation of implants, and it can be applied in various areas, such as the selection of surgical methods and the location of the implant. Moreover, it is essential to have good knowledge of the biomechanics of the hip to achieve better clinical results for patients. Therefore, this paper introduces the basic knowledge and biomechanical characteristics of a normal hip and hip replacement arthroplasty, which are needed to approach the biomechanics of the hip.

Background: Particulate matter 10 (PM10; airborne particles <10 μm) inhalation has been demonstrated to induce airway and lung diseases. In this study, we investigate the effects of PM10 inhalation on RNA expression in lung tissues using a murine model. Methods: Female BALB/c mice were affected with PM10, ovalbumin (OVA), or both OVA and PM10. PM10 was administered intranasally while OVA was both intraperitoneally injected and intranasally administered. Treatments occurred 4 times over a 2-week period. Two days after the final challenges, mice were sacrificed. Full RNA sequencing using lung homogenates was conducted. Results: While PM10 did not induce cell proliferation in bronchoalveolar fluid or lead to airway hyper-responsiveness, it did cause airway inflammation and lung fibrosis. Levels of interleukin 1β, tumor necrosis factor-α, and transforming growth factor-β in lung homogenates were significantly elevated in the PM10-treated group, compared to the control group. The PM10 group also showed increased RNA expression of Rn45a, Snord22, Atp6v0c-ps2, Snora28, Snord15b, Snora70, and Mmp12. Generally, genes associated with RNA splicing, DNA repair, the inflammatory response, the immune response, cell death, and apoptotic processes were highly expressed in the PM10-treated group. The OVA/PM10 treatment did not produce greater effects than OVA alone. However, the OVA/PM10-treated group did show increased RNA expression of Clca1, Snord22, Retnla, Prg2, Tff2, Atp6v0c-ps2, and Fcgbp when compared to the control groups. These genes are associated with RNA splicing, DNA repair, the inflammatory response, and the immune response. Conclusion Inhalation of PM10 extensively altered RNA expression while also inducing cellular inflammation, fibrosis, and increased inflammatory cytokines in this murine mouse model.

BACKGROUND: Hip fracture surgery (HFS) is often associated with perioperative blood loss, and it frequently necessitates transfusion. However, the hemoglobin (Hb) threshold for transfusion remains controversial in hip fracture patients. We evaluated the usefulness of the restrictive strategy and preoperative intravenous iron supplementation in HFS. METHODS: We retrospectively reviewed the medical records of 1,634 patients (> 60 years of age) who underwent HFS between May 2003 and June 2014 and were followed up for 1 year or more after surgery. We used the liberal transfusion strategy until May 2009 to determine the transfusion threshold; afterwards, we switched to the restrictive transfusion strategy. Patients with the restrictive transfusion strategy (restrictive group) received intravenous iron supplementation before surgery. We compared the transfusion rate, morbidity, and mortality of the restrictive group with those of the patients with the liberal transfusion strategy (liberal group). RESULTS: Preoperative intravenous iron supplementation was not associated with any adverse reactions. The transfusion rate was 65.3% (506/775) in the liberal group and 48.2% (414/859) in the restrictive group (p < 0.001). The mean hospital stay was shorter in the restrictive group (21.5 vs. 28.8 days, p < 0.001). There was no significant difference in the postoperative medical complications including myocardial infarction and cerebrovascular event. Mortality at postoperative 30, 60, and 90 days was similar between the two groups. CONCLUSIONS: Our blood management protocol involving restrictive strategy combined with preoperative intravenous iron supplementation appears to be effective and safe in HFS of elderly patients.

OBJECTIVE: To elucidate the effect of a 12-week horizontal vibration exercise (HVE) in chronic low back pain (CLBP) patients as compared to vertical vibration exercise (VVE). METHODS: Twenty-eight CLBP patients were randomly assigned to either the HVE or VVE group. All participants performed the exercise for 30 minutes each day, three times a week, for a total of 12 weeks. Altered pain and functional ability were evaluated using the visual analog scale (VAS) and Oswestry Disability Index (ODI), respectively. Changes in lumbar muscle strength, transverse abdominis (TrA) and multifidus muscle thicknesses, and standing balance were measured using an isokinetic dynamometer, ultrasonography, and balance parameters, respectively. These assessments were evaluated prior to treatment, 6 weeks and 12 weeks after the first treatment, and 4 weeks after the end of treatment (that is, 16 weeks after the first treatment). RESULTS: According to the repeated-measures analysis of variance, there were significant improvements with time on VAS, ODI, standing balance score, lumbar flexor, and extensor muscle strength (all p < 0.001 in both groups) without any significant changes in TrA (p=0.153 in HVE, p=0.561 in VVE group) or multifidus (p=0.737 in HVE, p=0.380 in VVE group) muscle thickness. Further, there were no significant differences between groups according to time in any of the assessments. No adverse events were noticed during treatment in either group. CONCLUSION: HVE is as effective as VVE in reducing pain, strengthening the lumbar muscle, and improving the balance and functional abilities of CLBP patients. Vibrational exercise increases muscle strength without inducing muscle hypertrophy.

Cancer immunotherapy, in the form of vaccination, adoptive cellular transfer, or immune checkpoint inhibitors, has emerged as a promising practice within the field of oncology. However, despite the developing field's potential to revolutionize cancer treatment, the presence of immunotherapeutic-resistant tumor cells in many patients present a challenge and limitation to these immunotherapies. These cells not only indicate immunotherapeutic resistance, but also show multi-modal resistance to conventional therapies, abnormal metabolism, stemness, and metastasis. How can immunotherapeutic-resistant tumor cells render multi-malignant phenotypes? We reasoned that the immune-refractory phenotype could be associated with multi-malignant phenotypes and that these phenotypes are linked together by a factor that acts as the master regulator. In this review, we discussed the role of the embryonic transcription factor NANOG as a crucial master regulator we named “common factor” in multi-malignant phenotypes and presented strategies to overcome multi-malignancy in immunotherapeutic-resistant cancer by restraining the NANOG-mediated multi-malignant signaling axis. Strategies that blunt the NANOG axis could improve the clinical management of therapy-refractory cancer.
