Purpose: This systematic literature review and meta-analysis explored extended reality (XR)-based pediatric nursing simulation programs and analyzed their effectiveness. Methods: A literature search was conducted between May 1 and 30, 2022 in the following electronic databases: MEDLINE, Embase, Cochrane Central Register of Controlled Trials (CENTRAL), and CINAHL. The search period was from 2000 to 2022. In total, 6,095 articles were reviewed according to the inclusion and exclusion criteria, and 14 articles were selected for the final content analysis and 10 for the meta-analysis. Data analysis was performed using descriptive statistics and the Comprehensive Meta-Analysis program. Results: XR-based pediatric nursing simulation programs have increased since 2019. Studies using virtual reality with manikins or high-fidelity simulators were the most common, with six studies. The total effect size was statistically significant at 0.84 (95% confidence interval=0.50-1.19, z=4.82, p<.001). Conclusion: Based on the findings, we suggest developing standardized guidelines for the operation of virtual pediatric nursing simulation education and practice. Simultaneously, the application of more sophisticated research designs for effect measurement and the combined applications of various virtual simulation methods are needed to validate the most effective simulation methodology.
This study aimed to systematically review the effectiveness of methylene blue (MB) photosensitizers in the management of symptomatic oral lichen planus (OLP). Electronic online databases and manual searches were performed for randomized controlled trials (RCTs) published in English between January 2010 and February 2022. RCTs comparing photodynamic therapy (PDT) and corticosteroid therapy at baseline and follow-up period were identified. The Cochrane risk of bias tool was used to assess the quality of the included studies. A meta-analysis was performed regarding visual analog scale (VAS) scores, Thongprasom sign scores, lesion size, response to treatment, and exacerbation of lesions after therapy. The clinical severity was analyzed qualitatively. Five RCTs consisting of 180 samples fulfilled the inclusion and exclusion criteria. All parameters of VAS score, Thongprasom sign score, lesion size, and response to treatment were statistically non-significant. Our results indicate that both MB-PDT and corticosteroid therapy are effective for the management of OLP. Moreover, MB-PDT is an effective alternative treatment option for OLP when corticosteroids are contraindicated. However, conclusive evidence cannot be ascertained owing to the heterogeneity among the studies.

Investigations on information security factors re- main elusive at small and medium enterprises (SMEs), es- specially for custom-made software solutions. This article aims to investigate, classify, adopt factors from recent literature addressing information security resources. SMEs al- ready have information security in place, but they are not easy to adopt through the negotiation processes between the in-house software development companies and custom-made software clients at SMEs. This article proposes a strategic framework for implementing the process of adoption of the information security factors at SMEs after conducting a systematic snapshot approach for investigating and classifying the resources. The systematic snapshot was conducted using a search strategy with inclusion and exclusion criteria to retain 128 final reviewed papers from a large number of papers within the period of 2001-2022. These papers were analyzed based on a classification schema including management, organizational, development, and environmental categories in software development lifecycle (SDLC) phases in order to define new security factors. The reviewed articles addressed research gaps, trends, and common covered evidence-based decisions based on the findings of the systematic mapping. Hence, this paper boosts the broader cooperation between in-house software development companies and their clients to elicit, customize, and adopt the factors based on clients' demands.

Aims: The purpose of our study was to evaluate the diagnostic performance of breast magnetic resonance imaging (MRI) in the evaluation of contralateral breast in patients with diagnosed breast cancer. A secondary objective was to determine accuracy of breast MRI in diagnosing multi-focal and multicentric lesions in the ipsilateral breast. Materials and Methods: Using a non-probability convenience sampling technique, patients with histopathologically diagnosed breast cancer with MRI of breast performed to exclude additional lesions were included. MRI findings were correlated with histopathology. In addition, follow-up imaging with mammography and ultrasound was also assessed for establishing stability of negative findings and for the detected of benign lesions. Results: Out of 157 MRI breast conducted during the period of 2008 to 2013, 49 were performed for patients with diagnosed breast cancer. The sample comprised of all females with mean age $50.7{\pm}11.0years$. The patient follow-up imaging was available for a period of 2-5 years. The sensitivity, specificity, and positive and negative predictive values of MRI in the detection of multifocal/multicenteric lesions was 85.7%, 88.8%, 60% and 96.6% respectively and for the detection of lesions in the contralateral breast were 100%, 97%, 83.3% and 100% respectively. Conclusions: Our study highlights the diagnostic performance and the added value of MRI in the detection of multifocal/multicenteric and contralateral malignant lesions. In patients with diagnosed breast cancer having dense breast parenchyma and with infiltrating lobular carcinoma as the index lesion MRI is particularly useful with excellent negative predictive value in the exclusion of additional malignant foci in the ipsilateral and contralateral breasts.
Objective: Rhus verniciflua Stokes (RVS) has anticancer effect confirmed by preclinical studies and historical records. We thus tried to evaluate retrospectively the effect of RVS as a complementary medicine for patients with advanced non-small-cell lung cancer (NSCLC) showing refractory to conventional chemotherapy. Patients and Methods: From June 1, 2006 to June 30, 2007, patients with advanced NSCLC who received both the standardized RVS extract and a standard course of second or more line therapy such as pemetrexed ($Alimta^{(R)}$), erlotinib ($Tarceva^{(R)}$), and gefitinib ($Iressa^{(R)}$) were checked. A total of 13 patients were eligible for the final analysis after fulfilling inclusion/exclusion criteria. Time to progression (TTP) of these patients treated with the standardized RVS extract was checked in the aftercare period. Results: Patients received RVS treatment for a median period of 296 (range 84-698) days. The median TTP was 220.5 (range 36-489) days, and three patients (23.1%) had TTP values of 15 more months. No significant side effects from RVS treatment have been observed. Conclusion: The standardized RVS extract might have synergetic effects by assisting apoptosis in advanced NSCLC with concurrent standard therapy agents, since it prolonged TTP without significant adverse effects. This study suggests that the standardized RVS extract is beneficial to patients with chemotherapy-refractory NSCLC. Further clinical trials and preclinical studies are necessary to determine the efficacy and safety of the standardized RVS extract in NSCLC.

Background: The number of cases employing thoracic endovascular aortic repair (TEVAR) has been increasing due to lower morbidity and mortality compared to open repair technique. The aim of this study is to evaluate the outcome of TEVAR for thoracic aortic diseases. Materials and Methods: Sixteen patients underwent TEVAR from October 2003 to April 2010. Mean age at operation was 59 years (20~78 years), and 11 were male. Indications for TEVAR were large aortic diameter (>5.5 cm) upon presentation in 6 patients, increasing aortic diameter during the follow-up period in 4, traumatic aortic rupture in 3, persistent chest pain in 2, and ruptured aortic aneurysm in one. The mean diameter, length and the number of the stents were 33 mm (26~40 mm), 12 cm (9.5~16.0 cm), and 1.25 (1~2), respectively. Aortography employing Multi-detector computerized tomography (MDCT) technique was performed at one week, and patients were followed up in the out-patient department at one month, 6 months, and one year postoperatively. Results: Primary technical success showing complete exclusion of the aneurysm was achieved in 15 patients. One patient showed a small endo-leak (type 1). Four patients developed perioperative stroke: Three recovered without sequelae, and one showed mild right-side weakness. There was no operative mortality. Diameter of the thoracic aorta covered by stent graft changed within 10% range in 12 patients, decreased by more than 10% in 3, and increased by more than 10% in one during mean follow-up duration of 18 months (1~73 months). There was no recurrence-related death during this period. Conclusion: Intermediate-term outcome after TEVAR was encouraging. Indications for TEVAR could be extended for other thoracic aortic diseases.

Background Infrabrow blepharoplasty has become a common surgical method used to rejuvenate aged upper eyelids in Asians. In this paper, we describe the parallel excision method for infrabrow blepharoplasty as a useful alternative to the conventional elliptical excision method. The authors' experience over a 3-year period is presented and reviewed. Methods A retrospective review of parallel excision infrabrow blepharoplasty cases at our hospital between 2014 and 2017 was performed. Three oculoplastic surgeons compared preoperative and postoperative photographs using the Strasser grading system. Results From the medical records of 123 patients, a total of 93 patients with moderate-to-severe bilateral dermatochalasis were selected as subjects. The exclusion criterion was levator function less than 8 mm. The total mean follow-up period was 2 years (range, 0.5-3.5 years). The mean skin excision height and width were 9.75 mm (range, 5-16 mm) and 58.51 mm (range, 42-75 mm), respectively. All patients who underwent surgery recovered without major complications, and all patients had high levels of satisfaction and improvements in their visual field. In the Strasser evaluation performed by the oculoplastic surgeons, most patients were found to have excellent results. Conclusions The parallel excision method for infrabrow blepharoplasty is a safe and effective technique that yields more natural- and youthful-looking eyelids than the conventional elliptical excision method. In our method, more effective manipulation of the orbicularis oculi muscle led to a reduction in frontalis compensation, resolution of sunken eyelids, and correction of lateral hooding.

Purpose: The living standards vary between the urban and rural areas in Korea. This study aims to compare the characteristics of acute poisoning victims in urban and rural areas. Methods: A retrospective study was conducted over a period of 2 years from 2008 to 2009. The study group included adults over 19 year old with acute poisoning and who were later were admitted to the local emergency medical center located in Daegu, Korea. The exclusion criteria were 1) the victims of adverse effects of therapeutic doses of drugs, 2) the victims with chronic exposure and 3) the victims who were missing data in their emergency medical records. We divided the victims into the adult group (19-64 years old) and the old group (over 65 years old). Results: There were 569 acute poisoning victims during the study period, and they constituted 1.11% of the total ED visits (51,199). Four hundred seventy six patients were enrolled in this study. Out of the 359 acute poisoning victims, 252 victims were from urban areas and 107 victims were from rural areas. They showed statistical differences for gender, ED access, transport, toxins and the time to the ED. In the old group, 61 victims out of 117 were from urban areas and the remaining 56 victims were from rural areas. They showed statistical differences for gender, ED access, toxins and transport. Conclusion: Through the clinical comparison between the acute poisoning victims of urban and rural areas, we exposed the clinical differences between the urban and rural areas, and we concluded that prevention and education for acute poisoning should be generated differently between the two groups.
This paper aims to research the historical development of the archival systems in the Soviet Union from 1917 to the 1920's. The Russian revolution was the turning point not only for the political and social changes but for the archival administration in Russia, as it provided the new Soviet regime with the chances to reorganize the archival institutions under Bolshevik rule. However, we must not forget the fact that the Russian Archival Workers' Union had taken part in the organization of the archival systems together with the Bolshevik revolutionaries. The Soviet government intended to transform the decentralized and poorly organized archival systems in the prerevolutionary years into the centralized and bureaucratized ones. In this meaning, the decree signed be V. I. Lenin on 1 June 1918 was estimated as the real basis for the Soviet archival centralization. Lenin's archival decree of 1918 encompassed the entire national documentary legacy, which was gradually extended to all types and categories of manuscripts and archival records by successive legislation. The concept of state proprietorship of all documentary records was designated "Single State Archival Fond"(Edinyi Gosudarstvennyi arkhivnyi fond), which was renamed as "Archival Fond of the Russian Federation" after the collapse of the USSR. The independent state administrative agency, that is, "Main Administration of Archival Affairs"(Glavnoe upravlenie arkhivnym delom) was charged with the management of the entire "Single State Archival Fond". While the Soviet Union reorganized its archival systems in the twenties, the archival institutions became under the severe control of the government. For example, M. N. Pokrovskii, the well-known Marxist historian and the political leader, headed the organizational work of archives in the Soviet Union, which resulted in the exclusion of the prerevolutionary specialists from the archival field in the Soviet Union. However, the discussions over the concept of "the Archival Fond" by B. I. Anfilov helped to develop the archival theories in the USSR in the twenties. In conclusion, the Soviet Union, having emphasized the centralization of the archives, developed its archival systems from the early period, which were the basis of the systematic archival institutions in Russia.
