Purpose: This study was conducted to update nursing practice guidelines for intravenous infusion published in 2017. Methods: The guideline update process was carried out using 22 steps developed by NICE and SIGN. It was agreed to update domains related to central venous infusion therapy. Contents related to peripheral infusion would be updated later. Results: Updated guidelines for central venous infusion therapy consisted of 6 domains and 195 recommendations. The number of recommendations by domain was 11 for general instruction, 14 for central vascular access devices (CVAD) and add-on devices, 13 for nursing management before insertion of CVAD, 30 for management during insertion of CVAD, 51 for management after insertion of CVAD, and 76 for complications. A grade was 29 (14.9%), B grade was 87 (44.6%), and C grade was 79 (40.5%) in the strength of recommendations. A total of 37 (19.0%) recommendations were newly developed and 23 (12.3%) previous recommendations have been modified. The newly developed recommendations were mainly related to the infection control methods. Conclusion: The updated guideline is focused on safe maintenance of central venous infusion therapy. Through this guideline, it is hoped to minimize the occurrence of complications and improve the standardization and efficiency of nursing practice.

An ulcer is defined as loss of epithelium. Although many oral ulcers have similar clinical appearances, their etiologies encompass many disorders, including trauma, infection, immunologic disease, and malignant oral cancer. Oral squamous cell carcinoma(SCC) occupying about 90% of oral cancer, usually manifests as unhealed ulcer over 2 weeks. Oral SCC can metastasize to the cervical neck lymph node, and therefore the surgical therapeutic modality for oral SCC could encompass the neck node dissection as well as wide excision for primary lesions, which should leave the post-operative complication of functional damage like dysphagia and facial deformity. Therefore, it is important to discriminate oral SCC from other ulcerative conditions to make a prompt management. The knowledge for the pathogenesis of the ulcerative lesions could help the clinicians to understand the differences of clinical features and to practice an appropriate therapeutics.

Regression models for determining infection periods of apple white rot were developed based on conidial germination and appressorium formation of Botryosphaeria dothidea. A total of 120 apple fruits were inoculated with the fungal conidial suspension and subjected to 6 temperatures and 10 wetness periods. Conidia germinated and produced appressoria, exhibiting swollen tips of germ tubes on the fruit surface. Conidial germination (G) increased with temperature (T) and wetness period (W), and was described as $G=-89.273+7.649T+7.056W-0.109T^{2}-0.085W^{2}-0.066TW(R^{2}=0.75)$. Less than 2 hr of wetness period were enough for conidia to germinate at 25 to $30^{\circ}C$. Effects of temperature and wetness period on appressorium formation (A) could be explained as $A=-1.540-2.375W+0.045W^{2}+0.213TW(R^{2}=0.77)$. The relationship between conidial germination and appressorium formation ($A_g$) was described as$A_g=0.381-0.227G+0.005G^{2}(R^{2}=0.67)$, suggesting that conidial germination may have to reach approximately $43.7\%$ to initiate appressorium formation. Using the regression equation for conidial germination and the criterion of $43.7\%$ conidial germination, an infection model was developed to determine infection periods based on temperature and wetness period. The infection model with the criterion of $43.7\%$ conidial germination was apparently more conservative than the appressorium formation model in determining possibility of apple infection. The infection model seemed sensitive to variable weather conditions, suggesting possible use of the model for timing fungicide sprays to control white rot of apples in practice.

Background: The impact of COVID-19 infection on workers' work function persists even after the acute phase of the infection. We studied this phenomenon in Japanese workers. Methods: We conducted a one-year prospective cohort study online, starting with a baseline survey in December 2020. We tracked workers without baseline work functioning impairment and incorporated data from 14,421 eligible individuals into the analysis. We estimated the incidence rate ratio for new onset of work functioning impairment due to COVID-19 infection during follow-up, using mixed-effects Poisson regression analysis with robust variance. Results: Participants reporting infection between January and December 2021 showed a significantly higher incidence of new work functioning impairment (adjusted incidence rate ratio: 2.18, 95% confidence interval: 1.75-2.71, p < 0.001). The formality of the recuperation environment correlated with a higher risk of work functioning deterioration in infected individuals (p for trend <0.001). Conclusion: COVID-19-infected workers may continue to experience work difficulties due to persistent, post-acute infection symptoms. Companies and society must urgently provide rehabilitation and social support for people with persistent symptoms, recognizing that COVID-19 is not just a transient acute infection.

Purpose: This study was undertaken to identify the risk factors of genital infection by examining the genital hygiene practice followed by adult women of reproductive age. The results can be applied as basic data for health education and health management on female genital hygiene practices. Methods: Data ware collected by conducting an online survey, comprising 200 adult women of reproductive age. Genital infections according to genital hygiene practice were analyzed by simple logistic regression. Results: In this study, the Odds Ratio (OR) of genital infection occurrence of genital hygiene practices used were disposable briefs 4.11 (CI 1.79-9.39, p=0.020), feminine deodorant spray 3.13 (CI 1.37-7.15, p=0.007), deodorant, vaginal inserts (tabs/supp) 10.60 (CI 3.97-28.28, p<0.001), over the counter anti-itch products 3.73 (CI 1.67-8.34, p=0.001), blotting 11.47 (CI 4.62-28.48, p<0.001), natural sea sponge 4.98 (CI 2.04-12.15, p<0.001), reusable cotton pads 5.76 (CI 2.48-13.33, p<0.001), tampons 2.60 (CI 1.17-5.77, p=0.019), tampons/pads between periods 4.79 (CI 2.07-11.10, p<0.001) and tampons/pads combination 4.11 (CI 1.79-9.39, p=0.001) Conclusion: Our results indicated the necessity to refrain from unnecessary application of genital hygiene practices, which is highly related to genital infections identified in this study. There is a need to continue education for proper performance.

The year of 2009~2010 brought a number of concepts and new ideas were evaluated with promising results. However, some studies that challenged many beliefs. In acute respiratory distress syndrome (ARDS), recent clinical studies took into consideration of pathophysiologic changes of respiratory system compliance. Meta-analysis of positive end-expiratory pressure trials showed survival benefit of high positive end-expiratory pressure in ARDS. Until now, prone positioning did not show survival benefit in patients with ARDS. Extracorporeal membrane oxygenation (ECMO) based management improved survival in patients with severe ARDS. ECMO can be a management option in severe ARDS. Sedation is a standard practice in critically ill patients needing mechanical ventilation. However, Danish group reported less sedation of critically ill patients receiving mechanical ventilation was associated with an increase in days without ventilation. Although this single center study has some limitations, the overall results are promising. Use of maximal sterile barrier precautions (mask, sterile gown, sterile gloves, and large sterile drapes) with chlorhexidine-impregnated dressing reduced central venous catheter related infection. Selective oropharyngeal decontamination (application of topical antibiotics in the oropharynx) reduced the mortality rate of an intensive care unit (ICU) population. Normoglycemia in Intensive Care Evaluation and Survival Using Glucose Algorithm Regulation (NICE-SUGAR) trial reported intensive glucose control increased mortality among adults in the ICU. Some of the results of above papers are promising. However, some ideas may need for more frequent individual assessment and increase the workload of ICU staffs. Before implementation of new practice in ICU, we should take into consideration of individual hospital situation including human and material resources.
