Perjuangan Jendral Soedirman Dalam Perang Gerilya Untuk Menumbuhkan Karakter Kepemimpinan Siswa SMA
Authors: Mukti Shofia Hamdallah 
Published: January 2022

<p><em>This study aims to analyze the struggle of General Sudirman in the Gerilya War to foster character education in high school students. The Gerilya War, which became the strategy of the Indonesian struggle led by General Sudirman, had a leadership concept to emulate together. For the freedom fighters of the Republic of Indonesia, Sudirman was not only a commander, but also a symbol of resistance to colonialism. He is also known as a wise open-minded leader and can always find a solution to every problem he faces. Through a literature study approach, this research tries to explain the concept of leadership that exists in the figure of General Sudirman with the character education of students in high school. Based on the results of the analysis that the Gerilya War Struggle led by General Sudirman has heroic values, both from his biography and leadership character from gerilya warfare. This leadership character must exist in the next generation, especially for high school students. It is hoped that the next generation will have an unyielding, courageous, optimistic spirit in facing the challenges of world globalization, so it is necessary to instill a tough character that comes from the leadership of General Sudirman in liberating the State of Indonesia. </em><strong></strong></p>
Recurrent Hemarthrosis Secondary to Erosive Patellofemoral Arthritis Treated with Arthroplasty
Authors: Turner Rachael A. , Duke Justin N. , Murray Trevor G. , Foran Jared R.H. 
Published: January 2022

Case:
Three patients presented with recurrent hemarthrosis secondary to erosive patellofemoral arthritis. Recurrent hemarthrosis from the eroded patellofemoral subchondral bone has not been well described. Each patient presented with symptoms secondary to painful effusions that were identified by aspiration. Each patient was successfully treated with patellofemoral or total knee arthroplasty

Conclusion:
Spontaneous or recurrent effusions in the setting of erosive patellofemoral arthritis should prompt orthopaedic surgeons to consider hemarthrosis as the cause of such effusions. Patellofemoral or total knee arthroplasty is effective in resolving the hemarthroses, resolving pain, and restoring function in these patients.
Increasing Timely Follow-up with Pediatric Orthopaedic Fracture Care
Authors: Bishop Courtney , Dolan Kevin , Balch Samora Julie 
Published: January 2022

Background:
Timely follow-up for radiographic and clinical evaluation with an orthopaedic specialist is critical in avoiding potential complications after pediatric long bone fractures. At our large, tertiary care, pediatric hospital, the baseline rate of timely follow-up after evaluation of reduced fractures in the emergency department was 74.4%. We tested the hypothesis that we could use quality improvement (QI) methods to increase the rate of timely follow-up and improve patient care.

Methods:
A multidisciplinary QI program was implemented with education for staff; improvement of procedures; patient and family education; and a method to identify and provide resources for potential barriers to follow-up. Questionnaire results were documented and tabulated.

Results:
At the end of the QI program, patient rates of timely follow-up were 78.5%, compared with the 74.4% baseline. There was no statistical difference in follow-up between patients who received and completed the questionnaire and those who did not. For patients who did complete the questionnaire, there was no statistical difference between those who identified a barrier to follow-up and those who did not identify any difficulty with follow-up.

Conclusions:
Minimal improvement was noted on the percentage of timely follow-up in the orthopaedic clinic after reduction of a fracture. Although the interventions fell short of their goals, future opportunities exist for improvement of timely follow-up.

Level of Evidence:
Level II (prospective cohort study).
From mommet to ugly: An analysis of the linguistic duality and idiolect of Tess Durbeyfield in the Spanish translations of Tess of the d’Urbervilles
Authors: López-Narváez Julia 
Published: January 2022

The current study aims at critically exploring the resulting identity of Tess of the d’Urbervilles’ main character, Tess Durbeyfield, in the Spanish translations through the analysis of her linguistic variation. Throughout the novel, Tess is characterised by a unique duality in linguistic variation, which shapes her identity. She is capable of using both dialectal and non-dialectal marks, which differentiates her from the rest of the novel’s characters. To reach thus the goal of this research, that is, to verify whether Tess Durbeyfield’s multifaceted identity is maintained in the Spanish translations, it is essential to analyse the linguistic variation of the novel’s heroine in the target texts. For the project, the three Spanish translations that exist of the novel have been analysed (carried out in 1924, 1994 and 2017).
In order to reach this aforementioned objective, the strategies carried out by the different translators regarding linguistic variation will be analysed, focusing on the possible identity distortion that these decisions may entail in the heroine’s characterization. In order to observe Tess Durbeyfield’s idiolect and linguistic variation, all dialogues from the novel and its corresponding translations have been analysed and classified. In the project, through selected dialogues, it will be observed whether the translation strategies regarding the heroine’s linguistic variation imply a reconfiguration of Tess’s identity in the target texts
Temporal Changes in Cyclin D-CDK4/CDK6 and Cyclin E-CDK2 Pathways: Implications for the Mechanism of Deficient Decidualization in an Immune-Based Mouse Model of Unexplained Recurrent Spontaneous Abortion

Abstract
Deficient endometrial decidualization has been associated with unexplained recurrent spontaneous abortion (URSA). However, the underlying mechanism is poorly understood. Here, we aimed to investigate the temporal cytokine changes and the involvement of the cyclin D-cyclin-dependent kinase (CDK)4/CDK6 and cyclin E-CDK2 pathways in the regulation of the G1 phase of the cell cycle during decidualization in a murine model of URSA. Serum and decidual tissues of URSA group and normal pregnant (NP) group mice were collected from gestation day 4 (GD4) to GD8. The embryo resorption and abortion rates were observed on GD8 and the decidual tissue status was assessed using hematoxylin and eosin staining. Cytokine levels in decidual tissues were analyzed using western blotting and reverse transcription polymerase chain reaction. We found that the embryo resorption rate was significantly increased in the URSA group compared to that in the NP group on GD8. The expression of the decidualization marker prolactin in the serum and decidual lysate of the URSA group was significantly decreased on GD6-8 compared to that of the NP group. Cyclin D, CDK4, CDK6, cyclin E, CDK2 and pRb levels in the URSA group mice were significantly lower compared to those in the NP group mice on GD6-8. Our results suggest that the hyperactivated cyclin D-CDK4/CDK6 and cyclin E CDK2 pathways inhibit the decidualization process on GD4, leading to deficient decidualization on GD8. Moreover, they clarify the role of cytokines in the cyclin D-CDK4/6 and cyclin E-CDK2 pathways during decidualization and provide new insight into URSA pathogenesis.
