To conduct a comprehensive evidence synthesis to verify the available literature on the effects of exercise intervention on muscle mass, muscle strength, and physical function in older adults with muscle wasting.Systematic literature searches of the PubMed/Medline, CINAHL, EMBASE, Cochrane Library, and Airiti Library databases were performed for exercise-related randomized controlled trials among adults aged 60 years and above with muscle wasting disease, published from 2010 to April 30, 2021. The search included the keywords and synonyms: "older," "sarcopenia," "cachexia," "muscle wasting," "exercise'.The systematic review included 34 studies: 25 on patients with sarcopenia and 9 on patients with cachexia. Sarcopenia and cachexia were analyzed as separate subgroups. The effects of exercise in the sarcopenia group showed significant improvement in the following parameters: body composition (appendicular skeletal muscle [ASM] [standardized mean difference, SMD 0.38, P = 0.05] and ASM/heightExercise intervention has significant benefits in older adults with muscle wasting diseases. More well-designed large-sample-sized studies with long-term follow-ups are warranted to verify the benefits of exercise intervention in this population.

The aim of this study was to develop and psychometrically test a new instrument for measuring nurse's positive energy of retention (NPER).The shortage of professional nurses is an unresolved global issue. Few studies explored the issue of the retention of nurses in terms of a positive psychological viewpoint.Methodological study.Data collection was from June 2016-August 2017. Nurses (N = 947) recruited from northern, central and southern Taiwan covering different levels of hospitals were divided into three samples, which were used for explaratory factor analysis (EFA), confirmatory factor analysis (CFA) and cross-validation respectively.EFA resulted in a three-factor solution: proactive and persevering characteristics, nursing professional identity and passion accounting for 61.8% of total variance. The proposed three-factor model was confirmed by CFA. Cross-validation provided further evidence for the construct validity of the NPER instrument with 24 items. Cronbach's alpha coefficient of three subscales of the instrument were 0.95, 0.89, and 0.92 separately and 0.96 for the total scale.Psychometric properties indicate that the newly formulated NPER instrument is a valid and reliable assessment tool to recruit nurses who are more likely to remain in nursing.The study addressed the personal intrinsic factors, which are very important for nurses' retention. The NPER instrument consisted of three subscales is a reliable and psychometrically valid new instrument. Managers could apply the NPER instrument to recruit nurses possessing the attributes of positive energy of retention. Furthermore, researchers could use the rigorous process provided in the study to establish a new instrument.目的: 本研究的目的是开发一种从积极心理学角度进行的测量护士护理人员留任意愿(NPER)的新型工具并对该方法进行心理测量。 背景: 专业护士短缺是一个尚未得到解决的全球性问题。很少有研究从积极心理学角度探讨护士留任问题。 设计: 方法研究。 方法: 本研究收集了2016年6月至2017年8月期间的数据,将来自台湾北部、中部及南部不同层级医院的护士(N = 947)分为三个样本,对样本分别进行了解释性因子分析(EFA)、验证性因子分析(CFA)及交叉验证。 结果: 解释性因子分析的结果显示为三因子解:积极和坚持的特点,护理专业认同和激情共占总方差的61.8%。提出的三因素模型得到了验证性因子分析的验证。交叉验证为24项NPER工具的结构有效性提供了进一步的证明。量表三个方面的克朗巴哈系数分别为0.95、0.89和0.92,总分为0.96。 结论: 心理测量学特性表明,新编制的NPER量表是一种有效、可靠的评估工具,可用于招聘更有可能继续留任的护士。 影响: 本研究探讨了个人内在因素对护士留任意愿的影响。NPER量表由三个分量表组成,是一种可靠的、心理测量有用的新型量表。管理者可以应用NPER量表招聘具有更愿意留任的护士。此外,研究人员可以利用研究中提供的严谨结果以编制其他新型量表。.

Aim To identify the 'positive energy' that inspires nurses' retention in the profession. Background Previous studies focused on the negative extrinsic factors associated with nurses leaving the profession. However, scant research explored the personal intrinsic essence regarding why nurses remain in the profession. Method This study used a qualitative descriptive design. Ten focus groups including 53 participants were recruited by purposive sampling from five hospitals in Taiwan. Data were collected between March 2015 and January 2016 through semi-structured focus group interviews. The data were examined by content analysis. Results Six themes were identified, including sense of mission, achievement, passion, meaning of nursing, personal characteristics and intrinsic coping. Conclusion Findings emerged from this study characterizing 'positive energy' as a steady inner strength, not easily changed with the external environment, which inspires the retention of staff nurses. Implications for nursing management The themes identified in this study can be used to develop an instrument for assessing nurses' inner attributes which may help managers recruit nurses possessing 'positive energy' of retention. Future researchers may develop an intervention programme to cultivate nurses 'positive energy' and further test its effect on nurse retention.

Background Health literacy (HL) influences a patient's comprehension and judgment of health-related information. A rigorous assessment tool is needed to screen for low HL in order to improve it. Objective The aim of this study was to develop and validate the Cancer Health Literacy Scale (C-HLS). Methods The framework of the C-HLS is based on the Levels of Prevention model. The scale items were developed according to Nutbeam's 3 constructs of HL. We employed several procedures to develop the C-HLS, including focus group interviews, item generation, the expert Delphi process, and face validity. Various types of analysis, including reliability and split-half reliability testing, confirmatory factor analysis, and criterion-related validity testing, were performed; receiver operating characteristic curve analysis was also performed to confirm sensitivity and specificity. Results There were 33 items included in the C-HLS for validation; 360 newly diagnosed cancer patients completed the survey. The administration time is only 10 to 15 minutes. Results showed that C-HLS had good reliability, split-half reliability, and validity. All confirmatory factor analysis model fit indices reached acceptable thresholds. The receiver operating characteristic curve analyses suggested that the C-HLS had an adequate combination of sensitivity and specificity to distinguish between high and low HL. Conclusions The C-HLS is a reliable, valid tool capable of discriminating levels of HL in the assessment of cancer patients and does not have an excessive administration time. Implications for practice This scale can aid our understanding of HL in newly diagnosed cancer patients and can serve as a basis for providing individual care interventions.

Tartrate-resistant acid phosphatase 5a (TRACP5a) is mainly secreted by activated macrophages in chronic inflammation. Serum TRACP5a is associated with symptom distress in lung cancer patients during chemotherapy. Therefore, this study aimed to investigate whether chemotherapy drugs modulate TRACP5a as an inducible marker for symptom distress in lung cancer patients during chemotherapy. In clinical analysis, lung cancer participants completely received the six-cycle chemotherapy process (n = 42). Clinical determinations for TRACP5a, C-reactive protein (CRP), interleukin-6 (IL-6), white blood cells, monocytes, and hemoglobin were analyzed at six time points: BL, C1d8, C2d1, C4d1, C4d8, and Ed28. Meanwhile, five questionnaires for fatigue, sleep disturbance, pain, depression, and confusion were finished before drug treatment. For monocyte-to-macrophage differentiation, THP-1 cells were treated with phorbol 12-myristate 13-acetate (PMA). TRACP5a secretion in THP-1 cells was determined at the following days up to 6 days after 1-day incubation of chemotherapy drugs by dot blotting. Clinical analysis revealed that TRACP5a significantly increased at C1d8 and C4d8, but dropped at C2d1 and Ed28. CRP and IL-6 displayed a broad-range variation, resulting in no significant difference among the assessment time points. In contrast, monocytes decreased at C1d8 and C4d8, but rose again at C2d1 and Ed28. In symptom distress, the changes only in fatigue and sleep disturbance were positively associated with the trend in TRACP5a. In PMA-treated THP-1 cells, TRACP5a significantly increased after stimulation with gemcitabine and paclitaxel. Taken together, induction of TRACP5a by chemotherapy drugs might be generated from monocyte-differentiated macrophages, further causing clinical symptom distress in lung cancer patients.

Objective: To evaluate the effect of a 12-week breathing-based leg exercises program on quality of life under stabilizing heart rate variability and reducing fatigue in regular hemodialysis patients. Design: Randomized controlled trial. Setting: A 94-bed hemodialysis department at a medical center in northern Taiwan. Participants: Eighty-six patients with end-stage renal disease undergoing hemodialysis were recruited and randomly assigned to the ExBr or control groups. Interventions: The breathing-based leg exercises program comprised abdominal breathing and low-intensity leg exercise, including leg lifts, quadriceps femoris contraction and knee flexion, and lasted for 15 minutes at one time, three times a week for 12 weeks. Main measure: Data was collected by using the World Health Organization quality of life assessment-brief, physiological signal recorder for heart rate variability and hemodialysis-related fatigue scale at baseline and on Week 4, Week 8, and Week 12. Results: Average (standard deviation) age was 53.70 (10.04) years in the ExBr group and 61.19 (10.19) years in the control group. The linear mixed model with adjusted age, creatinine, heart rate variability and fatigue revealed that the ExBr group had significantly higher quality of life than did the control group ( P = 0.01), especially on Week 12 ( P = 0.04). Fatigue was significantly correlated with quality of life ( P Conclusion: This study supported the benefits of the continued breathing-based leg exercises during hemodialysis for at least 12 weeks, which improved the quality of life of patients with end-stage renal disease and did not affect the stability of their vital signs.

Background and purposePressure injuries remain a significant health care issue in various settings. The purpose of this study was to examine the relationship between a pressure redistributing foam mattress (PRFM) and the development of pressure injuries.MethodsThis study employed an observational prospective cohort study design. We enrolled 254 participants from the intensive care unit who were at risk of developing pressure injuries. Participants were exposed to either a nonpressure redistributing foam mattress (NPRFM), which was the standard mattress used at the study site, or a PRFM made of viscoelastic, temperature-sensitive, polyurethane memory foam. The patients’ assignment to either a PRFM or NPRFM was performed upon their admission, before the study eligibility screening. The relationship between the PRFM and the development of pressure injuries was studied using a logistic regression model.ResultsThe overall incidence of pressure injuries was 5.9% (15/254) in our study, with 1.6% (2/127) for participants who used a PRFM and 10.2% (13/127) for those using a NPRFM. After adjusting for potential confounding variables, use of a PRFM was associated with an 88% reduced risk of pressure injury development (OR = 0.12, 95% CI: 0.03, 0.56, P = 0.007). The use of a PRFM also contributed to a postponed occurrence of pressure injuries by 4.2 days on average in comparison with that of a NPRFM (P= 0.041).ConclusionsA PRFM is associated with a significantly reduced incidence and postponed occurrence of pressure injuries. It is recommended to use a PRFM for patients at risk of developing pressure injuries.

This study aimed to review clinical experiences using whole-field simultaneous integrated boost (SIB) intensity-modulated radiotherapy (IMRT) and sequential IMRT in postoperative patients with oral cavity cancer (OCC). From November 2006 to December 2014, a total of 182 postoperative patients with OCC who underwent either SIB-IMRT (n = 63) or sequential IMRT (n = 119) were enrolled retrospectively and matched randomly according to multiple risk factors by a computer. The differences were well balanced after patient matching ( P = .38). The median follow-up time was 65 months. For patients treated with the SIB technique and the sequential technique, the respective mortality rates were 36.8% and 20.0% ( P = .04). The primary recurrence rates were 26.3% and 10.0% ( P = .02), respectively. The respective marginal failure rates were 26.7% and 16.7%. A multivariate logistic regression analysis showed that patients who received the SIB technique had a 2.74 times higher risk of death than those who received the sequential technique (95% confidence interval = 1.10-6.79, P = .03). Sequential IMRT provided a significantly lower dose to the esophagus (5.2 Gy, P = .02) and trachea (4.6 Gy, P = .03) than SIB-IMRT. For patients with locally advanced OCC, postoperative sequential IMRT may overcome an unpredictable geographic miss, potentially with a lower marginal failure rate in the primary area. Patients treated by sequential IMRT show equal overall survival benefits to those treated by SIB-IMRT and a lower mortality rate than those treated by SIB-IMRT. Additionally, a reduced dose to the esophagus and trachea compared to sequential IMRT was noted.

Background The purpose of this study was to review the risks and benefits of concurrent chemoradiation therapy (CCRT) with esophageal self-expandable metal stents (SEMS) for the treatment of locally advanced esophageal cancer. Materials and Methods Between January 2014 and December 2016, the data from 46 locally advanced esophageal cancer patients who received CCRT at our institution were retrospectively reviewed. Eight patients who received CCRT concomitant with SEMS placement (SEMS plus CCRT group) and thirty-eight patients who received CCRT without SEMS placement (CCRT group) were identified. The risk of developing esophageal fistula and the overall survival of the two groups were analyzed. Results The rate of esophageal fistula formation during or after CCRT was 87.5% in the SEMS plus CCRT group and 2.6% in the CCRT group. The median doses of radiotherapy in the SEMS plus CCRT group and the CCRT group were 47.5 Gy and 50 Gy, respectively. SEMS combined with CCRT was associated with a greater risk of esophageal fistula formation than CCRT alone (hazard ratio [HR], 72.30; 95% confidence interval [CI], 8.62–606.12; p Conclusion CCRT concomitant with SEMS for locally advanced esophageal cancer results in earlier life-threatening morbidity and a higher mortality rate than treatment with CCRT alone. Further prospective and randomized studies are warranted to confirm these observations. Implications for Practice Patients treated with SEMS placement followed by CCRT had higher risk of esophageal fistula formation and inferior overall survival rate compared with patients treated with CCRT alone. SEMS placement should be performed cautiously in patients who are scheduled to receive CCRT with curative intent.

Objective To evaluate the feasibility of an integrated outpatient-based screening program for oral cancer. Study Design An automated system was used to refer high-risk patients presenting to the outpatient clinic for oral cavity examination. The outcomes between the screened and concurrently symptomatic cohorts were compared to assess the program's effectiveness at identifying oral cancers. Results Among the 38,693 candidates flagged as high-risk patients by our automated referral system, a total of 8037 participants were recruited to our screened cohort; 1664 patients were identified with positive lesions, and 302 patients underwent a biopsy. Five patients were diagnosed with oral cancer and 121 with dysplastic precancers. The symptomatic cohort comprised 157 patients with oral cancers and 61 with precancers. The screening program identified earlier stages of oral cancers than in the symptomatic cohort. Conclusion Automated outpatient-based oral cancer screening programs may be a practicable strategy to identify precancerous lesions or early-stage cancers in high-risk adults.

Background. Microarray technology shows great potential but previous studies were limited by small number of samples in the colorectal cancer (CRC) research. The aims of this study are to investigate gene expression profile of CRCs by pooling cDNA microarrays using PAM, ANN, and decision trees (CART and C5.0).Methods. Pooled 16 datasets contained 88 normal mucosal tissues and 1186 CRCs. PAM was performed to identify significant expressed genes in CRCs and models of PAM, ANN, CART, and C5.0 were constructed for screening candidate genes via ranking gene order of significances.Results. The first screening identified 55 genes. The test accuracy of each model was over 0.97 averagely. Less than eight genes achieve excellent classification accuracy. Combining the results of four models, we found the top eight differential genes in CRCs; suppressor genes,CA7, SPIB, GUCA2B, AQP8, IL6RandCWH43;oncogenes,SPP1andTCN1. Genes of higher significances showed lower variation in rank ordering by different methods.Conclusion. We adopted a two-tier genetic screen, which not only reduced the number of candidate genes but also yielded good accuracy (nearly 100%). This method can be applied to future studies. Among the top eight genes,CA7,TCN1, andCWH43have not been reported to be related to CRC.

Background: Fatigue has been described as the most frequent and distressing problem of cancer patients undergoing chemotherapy. Objective: The aim of this study is to evaluate the validity and reliability of the Taiwanese version of the General Fatigue Scale (GFS-T) and to evaluate the severity of the fatigue among breast cancer patients in Taiwan. Methods: A cross-sectional research design was used, recruiting breast cancer patients from 2 medical centers in Taiwan. Patients completed the scale exploring their GFS-T, the Brief Fatigue Inventory–Taiwan Form, and the Eastern Cooperative Oncology Group Performance Status. The data were collected between the day before the first chemotherapy (T1) and 1 week after the first chemotherapy (T2). Results: A total of 171 patients participated in this study. Cronbach’s α for the GFS-T at both time points both were .94. Factor analysis generated 1 factor that accounted for 73.7% of variance in participants’ fatigue. The receiver operating characteristic curve analyses suggested that the GFS-T cut-point of 24 had an adequate combination of sensitivity and specificity to distinguish high and low performance status. The receiver operating characteristic curve is 0.67 (95% confidence interval, 0.59-0.75). Conclusions: The GFS-T is a reliable and valid instrument for assessing fatigue among cancer patients. Further research is needed to better understand predictors of cancer-related fatigue. Implications for Practice: The GFS-T can provide clinical nurses with a useful measure to assess fatigue in cancer patients.

Inpatient nursing care satisfaction is an important indicator of medical care quality. However, no reliable and validated tool is currently available in Taiwan to measure the satisfaction of inpatients with nursing care.This pilot study developed a reliable and validated scale for measuring inpatient nursing care satisfaction in Taiwan.First phase: literature review and expert focus group discussion constructs the content of the questionnaire to be used to assess inpatient nursing care satisfaction. Second phase: experts were requested to validate questionnaire content. Third phase: convenience sampling was used to recruit 766 inpatients from 6 hospitals to complete the validated questionnaire. The data collected from the questionnaire were analyzed using item analysis, construct validity, and internal consistency. The results of analysis were used to determine the reliability and validity of the developed scale.The 20-item Taiwanese inpatient nursing care satisfaction scale was developed, with a CVI (content validity index) of expert validity of .97, item discrimination CR (critical ratio) of 28.61-50.25 (p.001), and item-total correlation of .68-.84 (p.001). Two factors, including "professional knowledgeskill" and "environmental control" were extracted by exploratory factor analysis after the deletion of 5 items, with item factor loadings ranging from .61 to .84. The factors explained 71.40% of total variance. The internal consistency of the two categories of Cronbach's α was .94-.97 coefficient and the overall internal consistency coefficient was .97.This study confirms the validity of the developed Taiwanese inpatient nursing care satisfaction scale and suggests that this instrument is reliable for measuring the satisfaction of inpatients with nursing care in Taiwan.建構本土化住院病人對護理照護滿意度量表與信效度前驅檢測.住院病人對護理人員照護滿意度為重要醫療服務品質指標，然目前仍缺乏本土化具信效度之住院病人對護理照護滿意度評量工具。.建構本土化住院病人對護理照護滿意度量表，並進行信效度前驅檢測。.量表發展第一階段以文獻查證及專家焦點團體討論方式，彙整住院病人對護理照護滿意度項目並建構量表初稿；第二階段再以專家效度修定量表；而第三階段以方便取樣方式選取6家醫院，完成收案766位住院病人，藉由項目分析、建構效度及內在一致性分析等進行量表信效度檢測。.本量表共20題，專家效度CVI（content validity index）值.97，題項鑑別度CR（critical ratio）值為28.61–50.25（p.001），題項與量表總分相關係數為.68-.84（p.001）。經探索性因素分析，將題項刪減5題後共萃取出兩個因素，分別命名為「專業知能」及「環境控制」，各題項因素負荷量為.61-.84，量表總解釋變異量為71.40%，各構面內在一致性Cronbach's α值為.94-.97，量表整體信度為.97。.本研究建構之台灣住院病人對護理照護滿意度量表具良好信效度，可有效評估台灣住院病人對護理人員護理照護的滿意度。.

Background: Elderly persons with acute poisoning in the emergency department (ED) and prognostic factors of outcomes have not been well addressed in previous research. This study aimed to investigate the characteristics of elderly patients with acute poisoning visiting the ED, and to identify the possible predictive factors of mortality. Methods: Patients aged ≥ 65 years with acute poisoning who visited the ED in Taipei Veterans General Hospital from January 1, 2006 through to September 30, 2008 were enrolled in the study. We collected demographic information on underlying diseases, initial presentations, causes and toxic substances, complications, dispositions, and outcomes. Analyses were conducted among different groups categorized according to age, suicide attempt, and outcome. Multiple logistic regression was applied to identify possible predictive clinical factors influencing mortality in the elderly with acute poisoning. Results: A total of 250 patients were enrolled in the study, with a mean age of 77 years and male predominance. The most common cause of intoxication was unintentional poisoning. Medication accounted for 57.6% of poisonous substances, of which benzodiazepine was the most common drug, followed by warfarin. The overall mortality rate was 9.6%. The average length of stay in the ED increased significantly in the old (65–74 years), very old (75–84 years) and extremely old (≥ 85 years) groups. Suicide attempt patients experienced more complications including respiratory failure, aspiration pneumonia, hypotension and mortality. Three clinical predictive factors of mortality were identified: herbicide poisoning, hypotension and respiratory failure upon presentation. Conclusion: Our results demonstrated that elderly patients with acute poisoning had a mortality rate of 9.6%. Suicide attempts resulted in more serious complications. The risk factors for mortality were herbicide intoxication, hypotension and respiratory failure. [J Chin Med Assoc 2010;73(2):78–87]

Aims. The purpose of this study was to explore the relationships between specific nurse care-giving behaviours and preterm infant behavioural responses during bathing and to identify nurse behaviours associated with infant ‘stress’. Background. Although recent advances in medical technology have improved neonatal intensive care, the high mortality and morbidity rates in preterm infants have not decreased proportionally. As caregivers strive to reduce infant mortality and morbidity, a factor for consideration is which caregiver behaviours are associated with preterm infant well-being. Design. A descriptive correlational design. Method. Convenience samples of 24 preterm infants and 12 nurses were recruited. A total of 120 baths were videotaped. Infant and nurse behaviours were measured using the coding schemes developed by the researchers. Pearson coefficient correlation, non-parametric Kruskal–Wallis test, t-test and generalised linear models were methods for data analysis. Results. As nurses provided more support, stress was reduced in the infants, and their self-regulation during the bath was enhanced especially by the use of ‘containment’ and ‘positional support’. Conversely, non-therapeutic caregiver behaviours including ‘rapid and rough handling’ of the baby, ‘chatting with other people’ and ‘inappropriate handling’ increased infant ‘stress’ during the bath. Conclusion. The findings provide new information about the link between care-giving and infant responses and how caregivers can better interact with preterm infants during a very sensitive period of brain development. Relevance to clinical practice. How nurses take care of the preterm infants influences their responses to care-giving stimuli. To interact better with the infant during care-giving procedures, nurses need to provide more supportive care-giving behaviours especially ‘position support’ and ‘containment’ based on the infant’s needs, and avoid care-giving that may be too rough and occur too quickly without attending the baby’s stressful signals, positioning the baby in hyperextension posture, or chatting with other people during procedures.

This study was performed to explore the effects of a training program in developmentally supportive care (DSC) on nurse caregiving and preterm infant behavior during bathing in a neonatal unit. The study applied a single-group pretest and posttest design to analyze behaviors. Twenty preterm infants were bathed 120 times by 13 nurses. Indirect observation was adopted to collect all behavioral data. Results showed that infants felt less stress and nurses were more supportive during posttraining baths. Caregivers should receive training in DSC, and its applications could be expanded to other nursing caregiving activities.

Optimal molecular markers for detecting colorectal cancer (CRC) in a blood-based assay were evaluated.A matched (by variables of age and sex) case-control design (111 CRC and 227 non-cancer samples) was applied. Total RNAs isolated from the 338 blood samples were reverse-transcribed, and the relative transcript levels of candidate genes were analyzed. The training set was made of 162 random samples of the total 338 samples. A logistic regression analysis was performed, and odds ratios for each gene were determined between CRC and non-cancer. The samples (n = 176) in the testing set were used to validate the logistic model, and an inferred performance (generality) was verified. By pooling 12 public microarray datasets(GSE 4107, 4183, 8671, 9348, 10961, 13067, 13294, 13471, 14333, 15960, 17538, and 18105), which included 519 cases of adenocarcinoma and 88 controls of normal mucosa, we were able to verify the selected genes from logistic models and estimate their external generality.The logistic regression analysis resulted in the selection of five significant genes (P0.05; MDM2, DUSP6, CPEB4, MMD, and EIF2S3), with odds ratios of 2.978, 6.029, 3.776, 0.538 and 0.138, respectively. The five-gene model performed stably for the discrimination of CRC cases from controls in the training set, with accuracies ranging from 73.9% to 87.0%, a sensitivity of 95% and a specificity of 95%. In addition, a good performance in the test set was obtained using the discrimination model, providing 83.5% accuracy, 66.0% sensitivity, 92.0% specificity, a positive predictive value of 89.2% and a negative predictive value of 73.0%. Multivariate logistic regressions analyzed 12 pooled public microarray data sets as an external validation. Models that provided similar expected and observed event rates in subgroups were termed well calibrated. A model in which MDM2, DUSP6, CPEB4, MMD, and EIF2S3 were selected showed the result in logistic regression analysis (H-L P = 0.460, R2= 0.853, AUC = 0.978, accuracy = 0.949, specificity = 0.818 and sensitivity = 0.971).A novel gene expression profile was associated with CRC and can potentially be applied to blood-based detection assays.

Aim This study examined the effect of underlying contextual factors on the intention to stay in nurses. Background Workplace promotion, social support, work stress, job satisfaction and organisation-based self-esteem (OBSE) are psychosocial factors influencing the intention to stay in nurses. However, few studies have analysed the relationships among these factors. Method A cross-sectional survey was conducted and a sample was recruited in convenience sampling method from a medical centre in Taiwan. A total of 791 nurses completed a self-report questionnaire over a 3-month period in 2013. Results Social support, work stress, job satisfaction and OBSE significantly affected the intention to stay in nurses. Furthermore, social support and job satisfaction showed a positive direct effect on the intention to stay and an indirect effect on the intention to stay; the indirect effect was mediated by OBSE. Conclusion Organisation-based self-esteem mediates the effects of social support and job satisfaction on the intention to stay in nurses. Implications for Nursing Management The results showing the influence of OBSE on the intention to stay in nurses can serve as insight for hospital managers to make decisions when encouraging and managing employees.

To verify gene expression profiles for colorectal cancer using 12 internet public microarray datasets.Logistic regression analysis was performed, and odds ratios for each gene were determined between colorectal cancer (CRC) and controls. Twelve public microarray datasets of GSE 4107, 4183, 8671, 9348, 10961, 13067, 13294, 13471, 14333, 15960, 17538, and 18105, which included 519 cases of adenocarcinoma and 88 normal mucosa controls, were pooled and used to verify 17 selective genes from 3 published studies and estimate the external generality.We validated the 17 CRC-associated genes from studies by Chang et al (Model 1: 5 genes), Marshall et al (Model 2: 7 genes) and Han et al (Model 3: 5 genes) and performed the multivariate logistic regression analysis using the pooled 12 public microarray datasets as well as the external validation. The goodness-of-fit test of Hosmer-Lemeshow (H-L) showed statistical significance (P = 0.044) for Model 2 of Marshall et al in which observed event rates did not match expected event rates in subgroups of the model population. Expected and observed event rates in subgroups were similar, which are called well calibrated, in Models 1, 3 and 4 with non-significant P values of 0.460, 0.194 and 1.000 for H-L tests, respectively. A 7-gene model of CPEB4, EIF2S3, MGC20553, MS4A1, ANXA3, TNFAIP6 and IL2RB was pairwise selected, which showed the best results in logistic regression analysis (H-L P = 1.000, R (2) = 0.951, areas under the curve = 0.999, accuracy = 0.968, specificity = 0.966 and sensitivity = 0.994).A novel gene expression profile was associated with CRC and can potentially be applied to blood-based detection assays.

Background Microarray technology can acquire information about thousands of genes simultaneously. We analyzed published breast cancer microarray databases to predict five-year recurrence and compared the performance of three data mining algorithms of artificial neural networks (ANN), decision trees (DT) and logistic regression (LR) and two composite models of DT-ANN and DT-LR. The collection of microarray datasets from the Gene Expression Omnibus, four breast cancer datasets were pooled for predicting five-year breast cancer relapse. After data compilation, 757 subjects, 5 clinical variables and 13,452 genetic variables were aggregated. The bootstrap method, Mann-Whitney U test and 20-fold cross-validation were performed to investigate candidate genes with 100 most-significant p-values. The predictive powers of DT, LR and ANN models were assessed using accuracy and the area under ROC curve. The associated genes were evaluated using Cox regression. Results The DT models exhibited the lowest predictive power and the poorest extrapolation when applied to the test samples. The ANN models displayed the best predictive power and showed the best extrapolation. The 21 most-associated genes, as determined by integration of each model, were analyzed using Cox regression with a 3.53-fold (95% CI: 2.24-5.58) increased risk of breast cancer five-year recurrence… Conclusions The 21 selected genes can predict breast cancer recurrence. Among these genes, CCNB1, PLK1 and TOP2A are in the cell cycle G2/M DNA damage checkpoint pathway. Oncologists can offer the genetic information for patients when understanding the gene expression profiles on breast cancer recurrence.

To determine the inter-rater reliability, internal consistency, construct and concurrent validity and feasibility of the pain assessment scale for preterm infants.Repeated exposure to painful procedures has an adverse impact on preterm infants' health outcomes. Although many scales are available for assessing these infants' pain, only a few reliably and validly assess pain and no gold standard has been established in clinical practice.Instrument development and psychometric analysis.Preterm infants (n = 60) born 27·6-36·3 weeks gestational age were assessed for pain 3 minutes before (phase I), during (phase II), 3 minutes after (phase III) and the tenth minute after (phase IV) heel-stick procedures. Pain scores were independently coded from video recordings and observations by three trained nurses using our pain-assessment scale, premature infant pain profile and visual analogue scale.Scores on the pain assessment scale for preterm infants differed significantly across four phases of heel-stick procedures (F = 56·86, p0·0001). Internal consistency was 0·84 and inter-rater reliability was 0·88-0·93. Scores on our pain scale correlated well with scores on the premature infant pain profile (0·74-0·83) and visual analogue scale (0·72-0·81).The pain assessment scale for preterm infants integrates all possible pain indicators, with each item modified for clinicians' simple and easy pain measurement to potentially yield different information. Our scale is valid, reliable and feasible for preterm infants with gestational age27 weeks. Further examination of the scale's psychometrics is recommended with diverse samples of infants and different painful procedures.The pain assessment scale for preterm infants clearly defines item scoring and weighting, consistently discriminates different levels of pain and helps nurses to recognise infants' pain. Nurses can easily remember the definition of each item, allowing them to use our scale to evaluate preterm infants' pain at any time and to provide pain-relief interventions when needed.

This paper describes the experience of nursing a fire survivor in the intensive care unit (ICU). The survivor was sent to the ICU because of an inhalation injury combined with acute respiratory failure. Together with dyspnea, the patient was also experiencing post-traumatic responses. Care providers collected the data through observation and hand-written communication. It was after analyzing the data that we confirmed the patient to be experiencing the health problems associated with post-traumatic responses. The problem was the major focus of our caregiving. A good relationship was fostered with the patient through support and understanding while the patient's physical condition was stabilized. With appropriate nursing intervention and professional medical consultation, the patient's condition improved. In accordance with the physical condition of the patient, which they continued to monitor after the patient's return to the ward and subsequent discharge, the nurses provided continuous, holistic care. The patient recovered from the physical pain and psychological damage, as well as the depression and was able to resume a normal life.

The incidence of organophosphate poisoning (OPP) has increased rapidly recently. The poisoning affects the patient's condition quickly, and the patient's life can be endangered if there is a delay in transporting him to a place of treatment. Integral resuscitation knowledge and sensitive judgment are vital to patient care. The purpose of this investigation was to describe the treatment of a suicidal woman who had overdosed on organophosphate. Data were collected through the methods of direct patient care, observation, and communication, and problems were identified, such as risk of injury by organophosphate poisoning, and ineffective coping. During acute phases, the authors tried to keep the patient's airways clear, and respiration and circulation normal, and to maintain vital signs. Caregivers provided detoxicant, as well as repeatedly washing the patient's body in order to reduce the dangerous effects of organophosphate. In addition, psychological counseling was provided to the patient and her family. With this medical treatment the patient's condition improved. She became, furthermore, actively able to express her emotions and feelings. Having a good supportive system, the patient might face problems such as poor communication with the family, by seeking resources, and learning coping skills. This case report suggests that nurses should be equipped with the professional skills to enable them to deal with a poisoned suicidal patient, and to assess the patient's support system and family structure professionally. Caregivers' continuous assistance to the patient, moreover, is a significant element in the patient's rehabilitation.

Ten participants were recruited to explore the life attitudes of patients undergoing treatment for nasopharyngeal carcinoma. The subjects were interviewed using a semistructured interview guide. The interviews were tape recorded and then transcribed verbatim. Descriptions of the patients' life attitudes were analyzed using Colaizzi's phenomenologic method. Four themes emerged from this study and revealed that nasopharyngeal carcinoma patients can (1) build their confidence to survive and learn to embrace life, (2) develop a new love for self and others, (3) reinterpret their attitudes toward suffering and death, and (4) achieve life meaning by transcending their ego. The results of this study revealed that during treatment, patients with nasopharyngeal carcinoma learn to treasure their values of life through building up faith to survive, to adapt their attitudes of life in response to the impact of the illness, to reinterpret death through suffering in treatment, and to transcend self-ego to attain altruism. Our findings indicate that there is an urgent need to establish support groups in hospitals to effectively aid patients with nasopharyngeal carcinoma during treatment.

This project was aimed at improving the nursing of patients who have undergone total hip replacements. Investigation showed the following problems with existing nursing instruction in this area: lack of standard instruction, outdated educational materials, a 33.75% rate of completion of instruction lack of familiarity with instruction materials, and an average satisfaction score of 2.56 among nurses who have undergone instruction; The reading for patient's satisfaction with the guidance of nurses was 2.04. After site investigation, status analysis and reference check, we proposed the following program. (1) Establish standards and monitor tools for instruction for nursing total hip replacement patients, including "Caring standard", "Guidance for nursing instruction", "Nursing instruction sheet", "Notes at nursing instruction", "Satisfaction scoring system for nursing instruction"; (2) Carry out a training course to enhance nursing staff's knowledge about caring for patients with total hip replacement. After program had been implemented, a completion rate of 88.56% was achieved, and the satisfaction scores among nursing staff and patients were 4.3 and 4.36 respectively. This result shows that when we undertake reform at various different levels--including systemic structure, processing and monitoring--this can radically improve the quality of nursing instruction.
