ABSTRACT
PURPOSE: The recent trend of Internet-based digital health interventions has driven researchers to implement them to promote physical activity (PA) and improve patients' health outcomes. This systematic review and meta-analysis aim to evaluate the effects of Internet-based digital health interventions on PA and quality of life (QoL) in colorectal cancer (CRC) survivors. METHODS: We searched for relevant studies investigating the effects of internet-based digital health interventions published until Dec. 2022 in electronic databases (PubMed, CINAHL, EMBASE, Cochrane Central Register of Controlled Trials, and CEPS) according to PRISMA guidelines. The Joanna Briggs Institute critical appraisal checklist was used to examine the quality of the included studies. We performed the fixed and random effects model for meta-analysis. RESULTS: Among 746 identified studies, eight published between 2018 and 2022 were included. These covered 991 internet-based digital health interventions and 875 controls. After 6 months of internet-based digital health interventions, CRC survivors' performance in PA (standardized mean difference (SMD) = 0.23, 95% confidence interval [CI] = 0.09-0.38) and QoL (SMD = 0.11, 95% CI = 0.01-0.22) indicators improved significantly. CONCLUSIONS: Internet-based digital health improved the PA behaviour and QoL of patients with CRC. Because of differences in intervention outcomes, additional randomized controlled trials are warranted to provide suggestions for clinical practice. Internet-based digital health interventions are promising for promoting PA in CRC survivors.

BACKGROUND: Exposure to particulate matter (PM) may contribute to lung inflammation and injury. The therapeutic effect of N-acetylcysteine (NAC), a well-known antioxidant, with regards to the prevention and treatment of fine PM (PM2.5)-induced lung injury is poorly understood. This study aimed to determine the effect of PM2.5 on the recruitment of neutrophils and Ly6Chigh monocytes into lung alveoli and the production of proinflammatory proteins by stimulating the generation of reactive oxygen species (ROS), and to investigate the therapeutic effect of NAC on PM2.5-induced lung injury. METHODS: C57BL/6 mice were exposed to a single administration of PM2.5 (200 µg/100 µl/mouse) or phosphate-buffered saline (control) via intratracheal instillation. The mice were injected intratracheally via a microsprayer aerosolizer with NAC (20 or 40 mg/kg) 1 h before PM2.5 instillation and 24 h after PM2.5 instillation. Total protein, VEGF, IL-6, and TNF-α in bronchoalveolar lavage fluid (BALF) were measured. Oxidative stress was evaluated by determining levels of malondialdehyde (MDA) and nitrite in BALF. Flow cytometric analysis was used to identify and quantify neutrophils and Ly6Chigh and Ly6Clow monocyte subsets. RESULTS: Neutrophil count, total protein, and VEGF content in BALF significantly increased after PM2.5 exposure and reached the highest level on day 2. Increased levels of TNF-alpha, IL-6, nitrite, and MDA in BALF were also noted. Flow cytometric analysis showed increased recruitment of neutrophils and Ly6Chigh, but not Ly6Clow monocytes, into lung alveoli. Treatment with NAC via the intratracheal spray significantly attenuated the recruitment of neutrophils and Ly6Chigh monocytes into lung alveoli in PM2.5-treated mice in a dose-dependent manner. Furthermore, NAC significantly attenuated the production of total protein, VEGF, nitrite, and MDA in the mice with PM2.5-induced lung injury in a dose-dependent manner. CONCLUSION: PM2.5-induced lung injury caused by the generation of oxidative stress led to the recruitment of neutrophils and Ly6Chigh monocytes, and production of inflammatory proteins. NAC treatment alleviated PM2.5-induced lung injury by attenuating the ROS-mediated recruitment of neutrophils and Ly6Chigh monocytes and lung inflammation.

BACKGROUND: A massage may relax muscles, improve blood circulation and reduce pain and anxiety while also improving sleep quality by increasing comfort. However, there is little research on whether a back massage improves sleep quality in intensive care unit (ICU) patients. AIMS AND OBJECTIVES: This study examined the effects of a back massage on improving vital signs, sleep quality, anxiety and depression among ICU patients. DESIGN: Adopting a quasi-experimental design, convenience sampling was used to recruit ICU patients from a medical centre in Southern Taiwan. The experimental group received back massages for three consecutive days (n = 30), while controls received usual care (n = 30). METHODS: The Verran and Snyder-Halpern Scale and the Hospital Anxiety and Depression Scale were used, and subjective and objective sleep time (wrist actigraphy and sleep duration from nurse observations) was recorded. The effect of the intervention was examined using a generalized estimating equation model with a robust standard error and an exchangeable working correlation matrix adjusting for time. RESULTS: The results show that subjective sleep quality scores in ICU patients were low. Mean observed sleep time (measured by nurses) was 3·9 h, but mean sleep time measured using wrist actigraphy was 5·9 h. Back massages improved breathing in patients, increased sleep quality reflected by both subjective and objective data and were associated with a significant change in anxiety. CONCLUSIONS: These findings suggest that a 10-min back massage can improve sleep quality, sleep duration, breathing and anxiety in ICU patients. RELEVANCE TO CLINICAL PRACTICE: The implementation of a back massage shows positive improvements in the sleep quality of ICU patients. The training and theory of massage interventions should be further applied when developing courses in critical care nursing.

BACKGROUND: Cigarette smoking is a primary risk factor affecting mental and physical health worldwide. Many chronic diseases are closely related to smoking. Adolescents in Taiwan are increasingly using tobacco, especially in rural areas. OBJECTIVES: This research project used a mixed-method study to examine the effects of art therapy on smoking cessation in rural Taiwanese youth smokers. METHODS: Participants from years 10-11, were drawn from three senior high schools in Taiwan. The experimental group participated in a six-week smoking cessation intervention using art therapy. The comparison group participated in typical courses on smoking cessation. Quantitative measures included need for smoking, nicotine dependence, self-esteem, self-efficacy, and smoking cessation status. Qualitative analysis was based on phenomenology. RESULTS: A total of 66 students (n = 40 experimental group; n = 26 comparison group) were the subjects of quantitative analysis. No differences were noted in baseline characteristics of groups. Generalized estimating equation analyses suggested significant between-group differences in change from pre- to follow-up test scores in the "social domain" (B = -5.12, p < 0.05). Qualitative data (n = 17 experimental group; n = 10 control group) suggested three domains: effects of art therapy on smoking prevention, benefits of art therapy on other outcome measures, and comparison between art therapy and traditional smoking cessation programs. Conclusions/importance: The findings of this study can potentially contribute significantly to existing knowledge regarding the perceptions of art therapy on reoccurring tobacco use in Taiwanese youth.

BACKGROUND: Nonalcoholic fatty liver disease (NAFLD) is a global problem and pediatric obesity has risen dramatically. Early NAFLD might progress to nonalcoholic steatohepatitis (NASH) or liver cirrhosis and significantly increase liver disease-related mortality. We looked for NAFLD predictors in children and adolescents. METHODS: This community-based, cross-sectional study ran from December 2012 to September 2013 in southwestern Taiwan. Children <10 and >19 years old, with detected hepatic diseases, or who drank alcohol were excluded. The diagnosis of NAFLD was based on ultrasound: age, sex, anthropometric measurements, and laboratory data were evaluated for associated risks by using logistic regression analysis. Receiver operating characteristic (ROC) curves were used to determine cutoff values. RESULTS: We enrolled one thousand, two hundred and ten children (594 males; 616 females; mean age: 15.5 ± 2.8 years). Age, anthropometric measurements, and laboratory data were significantly higher in children with NAFLD. The association between NAFLD and the waist-to-height ratio (WHtR) was significant (adjusted odds ratio: 2.6; 95% confidence interval: 1.909-3.549; P < 0.001). It indicated highly suspicion of NAFLD (sensitivity: 70.1%; specificity 76.9%) when the WHtR for children and adolescents is above the cutoff value of 0.469. CONCLUSIONS: The WHtR might be a powerful index of the severity of pediatric NAFLD.

AIMS AND OBJECTIVES: To investigate the effects of threshold inspiratory muscle training in patients with stages II through IV chronic obstructive pulmonary disease using maximum inspiratory pressure, baseline dyspnoea index, 6-minute walk test and quality of life. BACKGROUND: A threshold inspiratory muscle training device provides pressure for inspiratory muscle strength, but there is limited information on the effects of threshold inspiratory muscle training starting at low pressure training. DESIGN: Randomised experimental design. METHODS: A total of 55 patients completed this study between September 2013-April 2014. The experimental group (n = 27) was provided medical treatment and routine care, along with five sessions of threshold inspiratory muscle training per week (21-30 min per session), accompanied by a progressive increase in the pressure threshold over a period of 8 weeks. The control group (n = 28) was provided medical treatment and routine care only, without intervention. In the inferential analysis, p values <.05 were considered to indicate statistical significance. RESULTS: After 8 weeks in the experimental group, mean maximum inspiratory pressure improved by -17.6 ± 0.18 cmH2 O, mean 6-minute walk test improved by 47.8 ± 1.46 m, and the baseline dyspnoea index increased from 4.48 ± 2.12 points to 9.0 ± 2.27 points. These data and quality of life were statistically different between the experimental and the control groups (p < .05). CONCLUSIONS: The threshold inspiratory muscle training can reduce patients' difficulties with respect to daily activities, thereby reducing the burden on the family, and improving prognosis in patients with moderate-to-very severe chronic obstructive pulmonary disease.

This study explored the effects of PM2.5 on hospital admissions (HAs) for acute exacerbation of chronic obstructive pulmonary disease (AECOPD) in southwestern Taiwan. Data on HAs for AECOPD, pollutants, and meteorological variables were obtained from the National Health Insurance Research Database and Environmental Protection Administration. The relative risks (RRs) of HAs for AECOPD was estimated using the Quasi-Poisson generalized additive model. A total of 38,715 HAs for AECOPD were recorded. The average daily HAs for AECOPD and mean 24-h average level of PM2.5 were 15.2 and 38.8 µg/m3, respectively. For both single and multiple pollutant (adjusted for O3 and NO2) models, increased AECOPD admissions were significantly associated with PM2.5 during cold season, with the RRs for every 10 µg/m3 increase in PM2.5 being 1.02 (95% CI = 1.007-1.040) at lag 0-1 in single-pollutant, and 1.02 (95 % CI = 1.001-1.042) at lag 0 day in multiple pollutant model. People 65 years of age and older had higher risk of HAs for AECOPD after PM2.5 exposure. The RRs of PM2.5 on HAs for AECOPD were robust after adjusting for O3 and NO2. Findings reveal an association between PM2.5 and HAs for AECOPD in southwestern Taiwan, particularly during cold season.

PURPOSE: To investigate the associated factors and change trajectories of quality of life (QoL), global outcome, and post-concussion symptoms (PCS) over the first year following mild traumatic brain injury (mTBI). METHODS: This was a prospective longitudinal study of 100 participants with mTBI from neurosurgical outpatient departments in Chiayi County District Hospitals in Taiwan. The checklist of post-concussion syndromes (CPCS) was used to assess PCS at enrollment and at 1, 3, and 12 months after mTBI; the glasgow outcome scale extended (GOSE), the quality of life after brain injured (QOLIBRI), Chinese version, and the Short Form 36 Health Survey (SF-36), Taiwan version, were used to assess mTBI global outcome and QoL at 1, 3, and 12 months after mTBI. RESULTS: Latent class growth models (LCGMs) indicated the change trajectories of QOLIBRI, PCS SF-36, MCS SF-36, GOSE, and PCS. Classes of trajectory were associated with age ≥40 years, unemployment at 1 month after injury, and educational level ≤12 years. Univariate analysis revealed that employment status at 1 month post-injury was correlated with the trajectories of QOLIBRI, PCS SF-36, MCS SF-36, and GOSE, but not PCS. CONCLUSIONS: Employment status was the most crucial associated factor for QoL in individuals with mTBI at the 1-year follow-up. Future studies should explore the benefits of employment on QoL of individuals with mTBI.

AIM: The aim of this study was to determine the diagnostic accuracy of the water swallow test for screening aspirations in stroke patients. BACKGROUND: The water swallow test is a simple bedside screening tool for aspiration among stroke patients in nursing practice, but results from different studies have not been combined before. DESIGN: A systematic review and meta-analysis was conducted to provide a synthetic and critical appraisal of the included studies. DATA SOURCES: Electronic literature in MEDLINE, EMBASE, CINAHL and other sources were searched systemically in this study. Databases and registers were searched from inception up to 30 April 2015. REVIEW METHODS: This systematic review was conducted using the recommendations from Cochrane Collaboration for Systematic Reviews of Diagnostic Test Accuracy. Bivariate random-effects models were used to estimate the diagnostic accuracy across those studies. The tool named Quality Assessment of Diagnostic Accuracy Studies (QUADAS-2) was used to evaluate the quality of the studies. RESULTS: There were 770 stroke patients in the 11 studies for the meta-analysis. The water swallow test had sensitivities between 64-79% and specificities between 61-81%. Meta-regression analysis indicated that increasing water volume resulted in higher sensitivity but lower specificity of the water swallow test. CONCLUSIONS: This systematic review showed that the water swallow test was a useful screening tool for aspiration among stroke patients. The test accuracy was related to the water volume and a 3-oz water swallow test was recommended for aspiration screening in stroke patients.

AIMS AND OBJECTIVES: To better understand chronic obstructive pulmonary disease patients' informational needs and associated factors using the Predisposing, Reinforcing and Enabling Causes in Educational Diagnosis and Evaluation model. BACKGROUND: Despite the increase in the incidence of chronic obstructive pulmonary disease, little research has been carried out on the information needs from a patient perspective. DESIGN: A cross-sectional, correlational design was used. METHODS: A convenience sample of 107 subjects was recruited from four Taiwanese hospitals. Multiple regression analyses were conducted to identify the total informational needs and related factors. RESULTS: Major findings were that (1) patients' top informational need was daily care, and (2) variables associated with the total information needs were younger age, greater health internal locus of control, less dyspnoea severity and greater social support. CONCLUSIONS: Patients' perceived chronic obstructive pulmonary disease informational needs are not congruent with the information received from healthcare professionals. RELEVANCE TO CLINICAL PRACTICE: Healthcare professionals need to be sensitive to the fact that treatment-related information was not the top priority of patients with chronic obstructive pulmonary disease. Healthcare professionals also need to target the special subpopulation of chronic obstructive pulmonary disease patients with greater total informational need to maximise educational impact.

OBJECTIVE: Cigarette smoking is highly prevalent, despite being a primary preventable cause of disease and mortality. This study examined the effect of a Transtheoretical Model (TTM)-based psychoeducational intervention for smoking cessation (SC) on knowledge, SC-related parameters, and progression through the TTM stages of change among rural smokers. METHODS: This quasi-experimental study recruited 200 smokers from an outpatient clinic. The comparison group was recruited before the experimental group to address possible self-selection bias. Structured questionnaires were administered pre- and post-intervention (three months) and at follow-up (six months). RESULTS: A generalised estimation equation model indicated that the TTM-based intervention significantly increased participants' SC-knowledge and improved progression through TTM stages by the six-month follow-up. No significant group differences were found in self-efficacy and nicotine dependence scores or daily cigarette consumption. CONCLUSIONS: A TTM-based intervention enhances SC-knowledge and fosters progress through change stages. However, it does not directly impact nicotine dependence or cigarette consumption. Outpatient settings may employ TTM-based programmes for SC education and motivation. Detecting anticipated effects may require a longer intervention duration exceeding six months. PRACTICE IMPLICATIONS: Such TTM-based programmes may facilitate SC-knowledge and motivation in outpatient settings. Further research to comprehend patients' context and experiences during the stages of change is required.

BACKGROUND: Oral cancer is the 2nd most common cause of death due to cancer in the south-western coastal region of Taiwan; the standardized mortality of oral cancer is higher than elsewhere in the world. According to the evidence, alcohol, betel-nut and cigarette (ABC) consumption cause oral, nasopharyngeal and related cancers. This study describes the relationships between ABC consumers and health promoting behaviors among community adults living around an area with a high prevalence of oral cancer. METHODS: A population-based, cross-sectional study design was conducted in oral cancer epidemic areas in south-western coastal Taiwan in 2010, 6,203 community residents over 20 years of age participated. Demographic data, ABC habits, and health-promoting behaviors were explored. A logistic regression analyses were used to identify factors associated with ABC consumers. RESULTS: A high percentage of participants consumed alcohol, betel-nut and cigarettes. Betel-nut and cigarette consumers took low levels of exercise, adopted a poor diet, and had poor oral hygiene. After adjusting for potential confounders, the logistic regression model indicated that middle aged males of poor education and low economic status, who did not exercise regularly and had poor oral hygiene, were more likely to chew betel quid and smoke cigarettes. CONCLUSIONS: It has identified that BC consumers are negatively associated with health promoting behaviors. Further research is required to understand the reasons why the subjects consume ABC, and explore ways to prevent initiation and enhance cessation of ABC habits in this population.

AIMS: To evaluate the self-perception of diabetes control associated with physical indicators and with practicing exercise and a healthy diet, among rural residents. BACKGROUND: It remains unclear whether a subject's self-perception of diabetes control increases its deleterious effects. DESIGN: Cross-sectional, correlational. METHODS: We recruited 715 participants from 18 primary healthcare centres in the rural regions of Chiayi County, Taiwan. Data were collected between 1 January 2009-30 June 2010. Logistic regression was conducted to identify the determinant factors associated with perceptions of diabetes control. RESULTS: A high percentage of participants overestimated their fasting blood glucose and HbA1 C status. Total cholesterol, triglyceride, low density lipoprotein cholesterol, blood pressure, and waist circumference exceeded the medical standard in the 'feel good' group, and many did not adopt a healthy diet and undertake physical activity. The final logistic regression model demonstrated that residents with diabetes who exercised frequently had normal fasting glucose, and normal HbA1 C tended to perceive 'feel good' control. CONCLUSION: Misperception and unawareness of diabetes control were prevalent among rural residents. Addressing misperceptions among rural residents with diabetes and increasing their knowledge of professional advice could be important steps in improving diabetes control in an elder population.

In general, over 70% absorbed nicotine is metabolized to cotinine and trans-3'-hydroxycotinine by cytochrome oxidase P450, and nicotine is also a major addictive and the psychoactive component in cigarettes. As a xenobiotic metabolism, hydrophobic compounds are usually converted into more hydrophilic products through enzyme systems such as cytochrome oxidase P450, sulfotransferases, and UDP-glucuronosyltransferases to deliver drug metabolites out of the cell during the drug metabolic process. In this study, an electrodeless electrochemical oxidation (EEO) reaction via Fenton reaction by producing free radical to react with nicotine to immediately monitor the oxidative products and metabolic derivatives of nicotine by tandem mass spectrometer (MS) is done. Fenton reaction generates free radicals via ferrous ion (Fe(2+)) and hydrogen peroxide (H2O2) to oxidize DNA and to degrade proteins in cells. In the EEO method, the oxidative products of nicotine including cotinine, cotinine-N-oxide, trans-3'-hydroxycotinine, nornicotine, norcotinine, 4-oxo-4-(3-pyridyl)-butanoic acid, 4-hydroxy-4-(3-pyridyl)-butanoic acid, and nicotine-N'-oxide were detected by tandem mass spectrometer to simulate the changes of nicotine and its derivatives in a time-dependent manner.

Maintaining a healthy caloric intake and expenditure balance is challenging. The preliminary study examined (a) the associations of Body Mass Index (BMI), body image, perceived stress, mental health, dietary habits, and exercise participation among 310 female college nursing students and (b) the differences in these factors among BMI subgroups. The cutoffs for underweight, normal weight, overweight, and obesity were <18.5 kg/m2, ≥18.5 but <23 kg/m2, ≥23 but <25 kg/m2, and ≥25 kg/m2, respectively. The survey used Multidimensional Body-Self Relations Questionnaire-Appearance Scale, Perceived Stress Scale, and Chinese Health Questionnaire (CHQ). Because of a non-normal distribution, non-parametric statistics were used. The study found that BMI correlated with body image. The lower the BMI, the higher the satisfactory score the participants rated. BMI was irrelated to diet, exercise, stress, and mental health. The participants were unlikely to eat under stress and negative moods. The underweight group (17.1%) had the highest satisfactory score on their appearance evaluation. There was no difference between the overweight (14.2%) and obese (11.0%) groups. Meanwhile, the median of perceived stress was 18 and the prevalence of mental disturbance was 45.2% based on the CHQ. Underweight, overweight, obesity, high perceived stress, and poor mental health among nursing students warrant attention. Nurse educators should strengthen their coping strategies and provide support. A longitudinal study may consider incorporating coping strategies into the study design.
ABSTRACT
Incense burning releases heavy particulate matter (PM) and nitrogen dioxide (NO2), known to have adverse effects on human health. Long-term exposure to PM and NO2 increases inflammatory cytokine levels and can induce respiratory diseases. This study examined the association between incense burning exposure and the health status, especially inflammatory biomarkers, of temple workers and volunteers in Taiwan. The longitudinal observational study compared adult temple workers and volunteers, with long-term incense burning exposure, to residents from outpatient clinics in the Chiayi area. Forced expiratory volume in 1 s (FEV1) and serum and exhaled breath condensate (EBC) cytokines were assessed. Nonparametric Mann-Whitney U tests were used to compare cytokine levels of the exposure and control groups during the cold and hot weather seasons. FEV1 was significantly more diminished in the exposed group than in the control group during the cold season. Exposure status was associated with greater hot-cold seasonal differences in serum interleukins (IL)-1ß (regression coefficient (B) = 6.6, 95% confidence interval (CI) = 5.0 to 8.3, p < .001), IL17-A (B = 2.4, 95% CI = 0.3 to 4.5, p = .03), and plasminogen activator inhibitor [PAI]-1 (B = 5.4, 95% CI = 1.5 to 9.3, p = .009). After adjusting for confounders, the groups' serum levels of IL-1ß, IL-17A, and PAI-1 significantly differed. EBC cytokines did not show significant differences. Elevated levels of IL-1ß, IL17-A, and PAI-1 have been associated with various autoinflammatory syndromes and diseases. Given the cultural significance of incense burning, culturally sensitive interventions, including education, policy development, and program implementation, are crucial to protect individuals' health, especially temple workers, from the adverse effects of exposure, addressing the manufacture, importation, and sale of incense.

The stromal cell-derived factor-1 (SDF-1)/CXC receptor 4 (CXCR4) axis has been shown to play a role in colorectal cancer progression. In addition, the protease urokinase-type plasminogen activator (uPA) is an important factor in tumor cell invasion and metastasis. However, the mechanism by which SDF-1 mediates uPA expression in human colorectal cancer cells remains unknown. We investigated the molecular mechanism governing the interaction between SDF-1 stimulation and uPA expression in three human colon cancer cell lines (DLD-1, SW48, and COLO 205). We found that SDF-1 stimulation led to an increase in the expression and secretion of uPA in these cells. Experiments involving specific inhibitors and small interfering RNA demonstrated that the activation of p38 mitogen-activated protein kinase (MAPK) and phosphatidylinositol 3-kinase (PI3K)/Akt pathways are critical for SDF-1-induced uPA expression. Analysis of transcription factor binding using ELISA and chromatin immunoprecipitation assays revealed that SDF-1 increased Sp1- and AP-1-DNA-binding activities in DLD-1 cells. Inhibition of Sp1 and AP-1 activation blocked the SDF-1-induced expression and activity of the uPA promoter. The effect of SDF-1 on DLD-1 signaling and uPA expression was mediated by the CXCR4/ß1 integrin axis. In summary, our findings elucidate the mechanisms of SDF-1/CXCR4 downstream signaling and provide insights into the function of SDF-1 in colon cancer cells.

AIMS: The purpose of this study was to investigate the effectiveness of chilled/un-chilled baby oil therapy for treating uremic pruritus in haemodialysis patients. BACKGROUND: Uremic pruritus affects 50-90% of haemodialysis patients, which makes it one of the most common medical problems in this population. Pruritus can cause skin infection, desquamation, pathological skin change, sleep disorder, anxiety, depression and social dysfunction. DESIGN: A prospective, pretest-post-test quasi-experimental design was used. METHODS: Haemodialysis patients with uremic pruritus were recruited and randomly assigned to one of three groups: experimental group 1 (chilled baby oil treatment; n = 30), experimental group 2 (un-chilled baby oil treatment; n = 31) and a control group (routine care only; n = 32). Participants in experimental group 1 and experimental group 2 were treated with chilled and un-chilled baby oil, respectively, for 15 minutes at least once daily for three weeks. The control group received no intervention other than standard care. Data collection included demographic data and itch severity. Medical records were also reviewed. RESULTS: The baseline characteristics of subjects in this study were as follows: 59% were male, mean age was 61·88 (SD 12·7) years, mean duration of haemodialysis was 5·31 years, mean duration of uremic pruritus was 40·58 (SD 37·8) months and mean intensity of uremic pruritus was mild. The anti-pruritic effects were significantly larger in subjects treated with either chilled or un-chilled baby oil than in those who received routine care. Anti-pruritic effects did not significantly differ between experimental group 1 and experimental group 2. CONCLUSIONS: The study confirmed that, for relieving pruritus in haemodialysis patients, either chilled or un-chilled baby oil is as effective as moisturising lotions and cooling soothing agents. RELEVANCE TO CLINICAL PRACTICE: Applying baby oil is a simple, safe, inexpensive and easily administered treatment for itchy skin in haemodialysis patients. By preventing or reducing uremic pruritus, baby oil treatment may also improve quality of life in this patient group.

BACKGROUND: Smoking cessation has been an important issue of concern for Taiwan's psychiatric nurses since promulgation of the Tobacco Hazards Prevention Act. However, Taiwan has lacked a qualified tool to evaluate the self-efficacy of nurses in providing smoking cessation services. PURPOSE: The purpose of this study was to validate the Chinese version of the Self- Efficacy in Smoking Cessation Service Scale (SE-SCS). METHODS: A back translation approach was used to develop the SE-SCS Chinese version. We enrolled 193 psychiatric nurses from two psychiatric centers in central and southern Taiwan to assess the reliability and validity of the Chinese version scale using internal consistency, test-retest, factor analysis, and concurrent criteria validity. RESULTS: The reliability of the SE-SCS Chinese version was assessed as good (Cronbach's α = .85) and the Pearson correlation for total test-retest score was acceptable (r = .65, p = .004). Explanatory factor analysis revealed that one factor explained 63.4% of total variance. As to the criteria validity, frequency of smoking cessation service provision was the main criterion, with a correlation of 0.25-0.26. We identified a low, but significant correlation (p < .001). CONCLUSION: The SE-SCS Chinese version appears to be a valid measure for assessing psychiatric nurse self-efficacy in providing smoking cessation services.

The disproportionate smoking prevalence among adolescents in rural Taiwan may be attributed to insufficient anti-smoking education. Increasing access to such education may help reduce initiation and promote smoking cessation in adolescents, particularly in rural areas. However, effects of these programs require verification. This study determined the effectiveness of a school-based prevention program in enhancing knowledge, attitudes, and anti-smoking exposure self-efficacy among seventh-grade non-smoking students. A quasi-experimental design with convenience sampling was employed, where participants included seventh graders from two junior high schools who completed a questionnaire 1−2 weeks before and after the intervention. Furthermore, the intervention group received four smoking and secondhand smoke (SHS) prevention classes, whereas the control group engaged in scheduled school activities. Knowledge on smoking (B = 4.38, p < 0.001) and SHS (B = 2.35, p < 0.001) were significantly greater in the intervention group. Moreover, the groups differed significantly in avoiding SHS exposure (B = 3.03, p = 0.031). Intervention modifications may be necessary to enhance the program's effect on smoking exposure-related attitudes and self-efficacy. Additionally, cultural and other aspects (or "urban-rural gap") might influence these results. Future randomized controlled trials should compare urban to rural adolescents, use longitudinal designs, and assess smoking initiation or cessation.
