A 49 year-old male was scheduled for a cholecystectomy, thereafter a 37 year-old female scheduled for removal of a epidural hematoma in the same operating room. Both of them had no specific medical problems and past medical histories for anesthesia. For those reasons, anesthesia was induced with thiopental sodium and succinylcholine with endotracheal intubation. After induction, vital signs including body temperatures were stable. But moisture dew in the unidirectional valves and corrugated tubes, and color changes of soda lime were discovered. At that time, severe hypercarbia was recognized by arterial blood gas analysis in both cases. In both cases, there were no malfunctions in unidirectional valves, expiratory valves, corrugation tubes, soda lime, ventilators and there connection parts in the anesthetic machines. Also there were no abnormalities of blood pressures, electrocardiograms, pulse oxymeters, temperatures and the pulse in the patient monitoring systems except capnography. At first, we thought that medical signs revealed malignant hyperthermias. But vital signs, air way pressures and functions of all kinds of anesthetic machine components including ventilators were normal. After discontinuing N2O gas deliveries in the operation room, hypercarbias disappeared. Thus, anesthetic gas delivery systems via central piping systems were checked and it was discovered that CO2 gas was in the N2O gas tank instead of N2O.

PURPOSE: The purpose of this study was to investigate the effect of the perceived nursing work environment (NWE) on person-centered critical care nursing (PCCN) practices among nurses in intensive care units (ICUs).METHODS: A cross-sectional research design was adopted for this study; participants were 126 ICU nurses working in five hospitals in B city. From December 2018 to February 2019, a survey questionnaire on NWE and PCCN were conducted. The collected data were analyzed with a multiple hierarchical regression analysis.RESULTS: The mean score for NWE was 2.98±0.39. Among the factors, basic work system was the highest (3.39±0.41), followed by leadership of the head nurse (3.31±0.55), interpersonal relationships (2.77±0.62), and institutional support (2.58±0.52). The mean score for PCCN was 3.52±0.46. Among the factors, comfort was the highest (3.77±0.62), followed by respect (3.55±0.56), compassion (3.43±0.60), and individuality (3.38±0.56). The interpersonal relationship (β =.31, p=.001) and the number of patients per shift (β =−.23, p=.005) had a significant effect on PCCN, accounting for 25.9% of the total variance.CONCLUSION: These results suggest that it is necessary to enhance the relationship-oriented culture and reduce the workload of nurses in order to improve the quality of nursing care in ICUs.

Purpose: This study examined the research trends using G-power centered on major Korean registered sites and presents the research trends of studies with a high level of evidence.Method: This study selected three research journals listed in the Korea Research Foundation among physical therapy journals in the field of physiotherapy. The selected papers were classified according to the following: 1) study type, 2) study level, and 3) quality of the study.Result: Sixty-nine articles were selected and classified according to the study type. The musculoskeletal system, central nervous system, and others comprised 73.91% (n=51), 17.39% (n=12), and 8.7% (n=6), respectively. The results were classified into 62 experimental studies, four observational analytic studies, and three descriptive studies. The experimental studies included 22 randomized controlled trials (level 2) and 40 non-randomized trials (level 3). Sixteen randomized controlled trials were classified for a qualitative evaluation, and 12 papers with a score of six or more (good) were found. Conclusion Many high-level studies were found in G-power, and the quality of the study was also good. Therefore, the effective number of samples obtained using G-power is one of the ways to enable high-quality research.

PURPOSE OF REVIEW: Rheumatoid arthritis (RA) is characterized by a chronic T-cell response that has escaped normal control mechanisms. This review summarizes recent insights in pathways that are functional in RA and that favor continuous and pathogenic T-cell activation. RECENT FINDINGS: T-cell activation is ultimately determined by positive signals from costimulatory molecules and negative signals from regulatory T cells. Blockade of the classic costimulatory pathway, CD28-CD80 or CD86, is beneficial in RA. Additional pathways that predominantly control the activation of memory and effector T cells are functionally important in synovial inflammation. Some of these costimulatory molecules(such as stimulatory killer cell immunoglobulin-like receptors and NKG2D) appear to be relatively specific for RA and not to play a role in normal immune responses. In addition to this predominance of positive signals, age-disproportionate decline in thymic activity in RA may lead to a diminution of regulatory T cells and loss of their negative signals. SUMMARY: The successful treatment trial of RA with CTLA-4Ig clearly documents the importance of T-cell costimulation in RA disease activity. Novel costimulatory pathways may be of even greater significance than CD28 in RA and may represent promising new therapeutic targets. The finding of reduced thymic activity in RA is exciting and will stimulate further studies of T-cell homeostasis and the function of regulatory cells.

PURPOSE: Renal scar or reflux nephropathy, known as a major cause of end-stage renal failure and hypertension in children and young adults, is frequently detected in pediatric urinary tract infection(UTI) patients at their first infections. So early and accurate diagnosis, and follow up of renal scar are very important. We performed this study to recognize the importance of radiologic examinations for detection of renal scar and vesicoureteral reflux(VUR) in pediatric UTI patients at their first attacks, and to compare the accuracy and usefulness of DMSA renal scan with renal ultrasonography and IVP in early detection and follow up of renal scar. We also wanted to find the association of renal scar with VUR detected by VCUG, and increased C-reactive protein(CRP) level. METHODS: We studied on 41 pediatric UTI patients without past medical history of UTI, who were admitted to the Department of Pediatics, Kangbuk Samsung Hospital from May 1993 to August 1995. On admission a blood sample was taken for the determination of CRP. Renal ultrasonography and DMSA renal scan were performed within five days after admission. Eight weeks later, with repeated studies of renal ultrasonography and DMSA renal scan, IVP and VCUG were also performed for all patients. RESULTS: 1) The incidence of UTI was most prevalent in infancy grou(56%). The ratio of male to female patients was 4.8:1 under the age of one year, and 1:2 over the age of one year. 2) At admission, 21 of 41 patients(51%) showed renal scars in the DMSA renal scans. At follow up of DMSA renal scans, 8 weaks later, 7 of 21 initially abnormal cases(33%) became normal while 14 cases(67%) continued to show renal scars. Twenty initially normal cases continued to show normal DMSA renal scans at follow up. 3) Renal ultrasonography showed 10 abnormal cases among 41 cases(24%) at admission, and 7 abnormal cases(17%) at follow up. IVP showed 13 abnormal cases among 41 cases(32%). 4) For detection of renal scar, sensitivity and specificity of DMSA renal scan were 95% and 100%, sensitivity and specificity of renal ultrasonography were 45% and 90%, and sensitivity and specificity of IVP were 59% and 100% retrospectively. 5) VCUG showed reflux in 13 patients among 41 patients(32%). Among 20 patients with normal DMSA renal scan, only two patients(10%) showed VUR in VCUG, and they were classified as grade I and II VUR by International Reflux Study Committee classifications. Among 21 patients with abnormal by DMSA renal scan, 11 patients(52%) showed VUR in VCUG, of whom 9 patients were classified as severe reflux above grade III. 6) The mean CRP level in the patients with normal DMSA renal scan was 9.6mg/L, significantly lower than mean CRP level of patients with abnormal DMSA renal scan which was 60.57mg/L(p<0.01). CONCLUSIONS: For early detection of renal scars and reflux nephropathy, appropriate radiologic investigations including DMSA renal scan and VCUG should be done to all pediatric UTI patients at their first attacks. DMSA renal scan seemed to be better radiologic method than renal ultrasonography and IVP in early detection of renal scar and have association with VUR. We also found that blood CRP level is easy and useful test for early suspection of upper UTI.
