Lower attenuation and higher kurtosis of coronary artery calcification associated with vulnerable plaque - an agatston score propensity-matched CT radiomics study.

BACKGROUND: Coronary artery calcification (CAC) burden assessed by Agatston score (AS) is currently recommended to stratify patients at risk for future acute coronary syndrome (ACS). Besides the CAC burden, the biostructure of CAC may also play a vital role in the vulnerability of CAC, which CT radiomics could reveal. Propensity-score matching of the traditional risk factors and CAC burden between the ACS and asymptomatic groups could radically remove biases and allow the exploration of characteristic features of CAC in ACS. METHODS: We retrospectively identified 77 patients with ACS who had a CAC scan before percutaneous coronary intervention between 2016 and 2019. These 77 patients were one-to-two propensity-score matched for traditional risk factors of ACS and AS ranks to select 154 subjects from 2890 asymptomatic subjects. A validation cohort of 30 subjects was also enrolled. Radiomics features of each plaque were extracted and averaged in each person. Conditional logistic regression and area-under-curve analysis were used for statistical analysis. RESULTS: A higher number of coronary segments involved, lower mean, median, first quartile, and standard deviation of attenuation, and increased kurtosis of attenuation of CAC were associated with the ACS group compared to the control group (p < 0.05 for all). Multivariable analysis showed that the lower median attenuation (OR = 0.969, p < 0.001) and higher Kurtosis (OR = 18.7, p < 0.001) were associated with the ACS group. The median attenuation and kurtosis significantly increase across AS ranks 1 to 4 (p = 0.001). The AUC of kurtosis (0.727) and median attenuation (0.66) were both significantly higher than that of the standard AS (AUC = 0.502) and the number of TRF (AUC = 0.537). The best cut-off of kurtosis at 2.74 yielded an accuracy of 74%, and the cut-off of median attenuation at 196 yielded an accuracy of 68%. The accuracy of kurtosis was 64%, and the accuracy of median attenuation was 55% in the validation cohort. CONCLUSION: After propensity-matching traditional risk factors and CAC burden, CT radiomics highlighted that lower median attenuation and higher kurtosis were the CAC characteristics of vulnerable plaques. These features improve the understanding of the biomechanics of CAC evolution and enhance the value of CAC scan in ACS risk assessment.

Randomized Controlled Study of Tenofovir versus Lamivudine Followed by Tenofovir in Severe Exacerbation of Hepatitis B.

Spontaneous severe acute exacerbation (SAE) is not uncommon in the natural history of chronic hepatitis B (CHB). Lamivudine (LAM) has the advantages of low price, quick onset, good efficacy, and no drug resistance within 24 weeks. This study aimed to compare the short-term efficacy of tenofovir disoproxil fumarate (TDF) and LAM for 24 weeks followed by TDF in the treatment of CHB with severe acute exacerbation. Consecutive patients of CHB with SAE were randomized to receive either TDF (19 patients) or LAM for 24 weeks, followed by TDF (18 patients). The primary endpoint was overall mortality or receipt of liver transplantation by week 24. This study was approved by the Institutional Review Board (IRB) of the Kaohsiung Veterans General Hospital (VGHKS12-CT5-10). The baseline characteristics were comparable between the two groups. By week 24, seven (37%) and five (28%) patients in the TDF and LAM-TDF groups died or received liver transplantation (P = 0.487). Multivariate analysis showed that albumin level, prothrombin time (PT), and hepatic encephalopathy were independent factors associated with mortality or liver transplantation by week 24. Early reductions in HBV DNA of more than or equal to 2 log at 1 and 2 weeks were similar between the two groups. The biochemical and virological responses at 12, 24, and 48 weeks were also similar between the two groups. TDF and LAM for 24 weeks followed by TDF achieved a similar clinical outcome in CHB patients with SAE. (This study has been registered at ClinicalTrials.gov under identifier NCT01848743).

Comparing efficacy of a single intraarticular injection of platelet-rich plasma (PRP) combined with different hyaluronans for knee osteoarthritis: a randomized-controlled clinical trial.

BACKGROUND: Intraarticular plasma-rich platelet (PRP) and hyaluronic acid (HA) have each been shown to be effective for treating knee osteoarthritis (OA). Evidence supporting the combination therapy is controversial. This study aimed to investigate the efficacy of a single intraarticular PRP injection combined with different HAs in patients with knee OA. METHODS: In this prospective randomized-controlled trial, 99 patients with Kellgren-Lawrence grade 2 knee OA with average knee pain ≥ 30 mm on a 0-100 mm pain visual analog scale (VAS) were randomized into two groups. The PRP + Artz group received a single intraarticular HA (Artz, 2.5 ml, 10 mg/ml) followed by 3 ml PRP (n = 50). The PRP + HYAJOINT Plus group received a single intraarticular cross-linked HA (HYAJOINT Plus, 3 ml, 20 mg/ml) followed by 3 ml PRP (n = 49). All patients were evaluated before and at 1, 3 and 6 months after injections. The primary outcome was the VAS pain reduction from baseline at 6 months. Secondary outcome measures included Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), Lequesne index, single leg stance (SLS) test and patient satisfaction. RESULTS: Ninety-five patients were analyzed by intention-to-treat analysis. Both groups improved significantly in VAS pain, WOMAC, Lequesne index and SLS at 1, 3 and 6 months post intervention (p < 0.05). Between-group comparisons showed no significant differences at most follow-up time points, except better improvements in Lequesne index at 1 month (p = 0.003) and WOMAC-stiffness score at 6 months (p = 0.020) in the PRP + Artz group, and superiority in SLS at 1, 3 and 6 months in the PRP+ HYAJOINT Plus group (p < 0.001, p = 0.003 and p = 0.004). Additional Johnson-Neyman analyses showed that among the patients with baseline WOMAC-pain score > 8.5, WOMAC-function score > 21.7 and WOMAC-total score > 32.0, respectively, those treated with PRP + HYAJOINT Plus injections had better effects in WOMAC-pain, WOMAC-function and WOMAC-total scores than those treated with PRP + Artz at 3 months postinjection (p < 0.05). Both groups reported high satisfaction. No serious adverse events occurred during the study. CONCLUSIONS: A single PRP injection combined with Artz or HYAJOINT Plus is effective and safe for 6 months in patients with knee OA. Both injection regimens are potential treatment options for knee OA. Further studies are needed to confirm these results. TRIAL REGISTRATION: The study was registered at ClinicalTrials.gov (NCT04931719), retrospectively. Date of registration 18/6/2021. NAME OF TRIAL REGISTRY: Comparing efficacy of single PRP combined with different hyaluronans for knee osteoarthritis. LEVEL OF EVIDENCE: Therapeutic Level 1.

Demoralization level fluctuated at various time frame of radiotherapy for patients with different cancers: a longitudinal observational study.

BACKGROUND: Demoralization is a psychological response that is frequently observed in patients with cancer or advanced diseases. It is affected by national characteristics, culture, disease characteristics and general conditions of the patient such as individual cultural features, nature of stress, personal expression preferences and social behavior. Compared with the results of previous studies on demoralization syndrome, patients with cancer in Taiwan exhibit a higher prevalence of demoralization. We aimed to investigate the prevalence of high demoralization and the changes in the level of demoralization in cancer patients during radiotherapy to explore the associated factors and the contributing factors to the high level of demoralization. METHODS: We used the Demoralization Scale-Mandarin Version to evaluate the demoralization level at six-time points in patients admitted for radiotherapy in a 3-month observational period. 101 patients allocated to three groups by cancer region completed the study. We applied the generalized estimating equation (GEE) to analyze the changes in the demoralization level among the three groups. The variables associated with the changes in the demoralization level were also investigated. RESULTS: In the analysis using univariate GEE, only patients in the chest and breast group exhibited significant changes at two different time points. The results obtained using multivariate GEE revealed that sociodemographic variables, stage of disease and use of surgery or chemotherapy had no impact on the changes in demoralization across three months. CONCLUSION: The demoralization level certainly fluctuated in an extremely high range. The higher prevalence of demoralized patients may indicate that if medical staff neglect the importance of demoralization, demoralized patients with cancer may not receive appropriate care.

Relationship between Walking Activity and Sleep Quality among Community-Dwelling Older Adults.

PURPOSE: To explore the relationship between walking activity and sleep quality among elderly. DESIGN: A cross-sectional, correlation study with purposive sampling was conducted on participants with a walking habit but not regular moderate-intensity exercise. METHODS: Data were collected by structured questionnaires, including the Walking Activity Questionnaire and the Pittsburgh Sleep Quality Index. FINDINGS: The total walking time per week and frequency of walking per day were significant predictors of sleep quality. CONCLUSIONS: Walking can help older community-dwelling adults improve their sleep quality. CLINICAL EVIDENCE: Walking more than once per day and total walking time per week ≥210 minutes were associated with good sleep quality.

Predicting in-hospital mortality for dementia patients after hip fracture surgery - A comparison between the Charlson Comorbidity Index (CCI) and the Elixhauser Comorbidity Index.

BACKGROUND: Considerable in-hospital mortality was reported in geriatric patients with dementia sustaining femoral neck or inter-trochanteric fracture. We intended to establish a predictive model of in-hospital mortality for dementia patients after hip fracture surgery. METHODS: We collected 8080 registrants ≧ 65 years old from the subset (LHID2000) of the National Health Insurance Research Database (NHIRD) that met the following inclusion criteria:1. Admitted with the ICD of hip fracture; 2. Underwent operation of hip fracture during the same hospitalization; 3. Co-existing diagnosis of dementia (ICD-9-CM codes 290). The co-morbidity was recorded according to validated Charlson Comorbidity Index (CCI) and Elixhauser Comorbidity Index (ECI) from the diagnoses of hospitalization. The main outcome measure was in-hospital mortality that was defined as death being reported during hospitalization. The comparison of predictability was conducted by Receiver operating characteristic (ROC) curves and the area under the ROC curve (AUC) among different predictive models. RESULTS: The Charlson Comorbidity Index (CCI) score and Elixhauser Comorbidity Index (ECI) score showed similar ability in predicting in-hospital mortality (AUC = 0.653, 95% CI = 0.611-0.695 for CCI; AUC = 0.624, 95% CI = 0.582-0.665 for ECI, p = 0.0717). By adding age grouping (≥80 yrs = 1, 65-80 yrs = 0) and gender difference (Male = 1, Female = 0), these two models were shifted to models CCI_new1 and ECI_new1. Consequently, the AUC greatly increased in the CCI_new1 (AUC = 0.682, 95% CI = 0.643-0.722). It therefore provided better prediction of in-hospital mortality than ECI_new1 (AUC = 0.651, 95% CI = 0.611-0.691) (p = 0.0444). CONCLUSIONS: Utilizing the CCI with addition of grouping for age and gender provides a better prediction for in-hospital mortality than the ECI among elderly patients with concomitant dementia and hip fracture who underwent surgical intervention.

Tumor origin and symptom distress of radiotherapy affected fluctuation of purpose in life for cancer patients.

This study was to explore the change in purpose in life (PIL) and symptom distress among cancer patients with radiotherapy and associated risk factors. This was a longitudinal study.160 patients were recruited from a medical center in Southern Taiwan. Surveys were conducted one week before and one week after the patients had radiotherapy by questionnaire. Multivariate regression analysis were performed to analyze the data. The patients had significant changes in PIL after radiotherapy compared to before. They had low PIL scores when they were at stage IV, were unable to receive surgery, had tumors in sites other than the abdominal cavity and pelvic, or had high scores in symptom distress scale. Our findings empirically demonstrated that the sense of meaning is integrally associated with the physical and psychosocial effects of illness. Given that cancer patients who are at an advanced stage, unable to receive surgery and have tumors at sites that are not the abdominal cavity and pelvis are at a high risk for having low PIL after RT, care services should be directed to the patients under these conditions.

Efficacy and Safety of a Single Intra-articular Injection of Platelet-rich Plasma on Pain and Physical Function in Patients With Ankle Osteoarthritis-A Prospective Study.

Ankle osteoarthritis (OA) can cause disabling symptoms, and some patients prefer to be treated with minimally invasive procedures. The aim was to evaluate the efficacy and safety of a single intraarticular injection of platelet-rich plasma (PRP) for patients with ankle OA. In a prospective study done in a university-affiliated tertiary care medical center, 44 patients with symptomatic ankle OA for at least 6 months were recruited. Patients received a single injection of PRP (3 mL) into symptomatic ankles. The primary outcome was the change from baseline in the visual analog scale (VAS) pain (0-10 cm) at 6 months. Secondary outcomes included the Ankle Osteoarthritis Scale (AOS) score, American Orthopedic Foot and Ankle Society (AOFAS) hindfoot-ankle score, single-leg stance test (SLS), rescue analgesics consumption and patient satisfaction. Thirty-nine participants (88.64%) completed the study. Significantly improvement in the VAS and AOS was noted at 1-, 3-, and 6-month follow-ups (p < .001). The mean VAS pain decreased significantly from 4.1 ± 1.7 at baseline to 2.2 ± 1.9, 1.7 ± 1.5, and 1.8 ± 1.6 at 1, 3, and 6 months (p < .001). The mean total AOS score reduced by 1.5, 2.2, and 2.1 from baseline respectively postinjection (p < .001). The mean AOFAS hindfoot-ankle score improved from 80.3 points at baseline to 87.2, 91.6, and 89.7 points at 1, 3, and 6 months (p < .001). SLS tests improved significantly (p < .001) at each follow-up. Acetaminophen consumption dropped significantly (p < .001) and no serious adverse events occurred. The study showed promise for a single intraarticular injection of PRP in the treatment of ankle OA.

Intraocular pressure might play a role in the surgical management of patients with epiretinal membrane.

PURPOSE: To investigate the prognostic factors and visual outcomes for patients with epiretinal membrane after pars plana vitrectomy and possible interactions between multiple factors. METHODS: A retrospective chart review of adult patients with epiretinal membrane treated with pars plana vitrectomy performed by a single surgeon between February 1, 2015, and January 31, 2017 was conducted. The surgical procedures included standard 25-gauge vitrectomy with peeling of the epiretinal membrane and internal limiting membrane (ILM). Factors including age, sex, vision, intraocular pressure (IOP), lens status, and baseline optical coherence tomography angiography were analyzed to determine any association with visual outcomes. IOP and lens status were evaluated at every visit point and were used for analysis. RESULTS: Visual changes after pars plana vitrectomy in patients with epiretinal membrane were significantly associated with time, lens status, baseline ellipsoid zone integrity, baseline vision, baseline parafoveal vessel density of superficial capillary plexus (SPVD), and IOP. Further investigation using Johnson-Neyman analysis revealed that vision improved over time, especially in pseudophakic eyes. High IOP at baseline or during follow-up was identified as a significant factor associated with limited visual improvement. CONCLUSION: Our study showed that vision improved over time after vitrectomy for patients with epiretinal membrane. The surgical outcomes are more stable in pseudophakic eyes, and vision improved after cataract extraction in phakic eyes. IOP should be managed and monitored closely to optimize surgical and visual outcomes in patients.

[The Effectiveness of a Mindfulness-Based Intervention in Reducing Relocation Anxiety and Promoting Adaptation in Older People With Diabetes].

BACKGROUND: Relocating from home to a long-term facility is frequently a stressful event for older persons with diabetes. Therefore, it is important that nurses have available an intervention program that effectively reduces relocation anxiety and promotes adaptation in this population. PURPOSE: To evaluate the effectiveness of a mindfulness-based intervention in reducing relocation anxiety and promoting adaptation in older persons with diabetes. METHODS: Four long-term care facilities in Kaohsiung City were selected as the study sites. Residents of these facilities who had diabetes and who had moved in within the previous year were recruited as participants using a simple random-sampling method. The experimental group (n = 34) received a 9-week mindfulness-based intervention and the control group (n = 32) received routine diabetes care and maintained their normal daily routine. Outcome measurements included a demographic datasheet, the Taiwanese version of the State Anxiety Inventory, and the individual mental factors subscale of the elderly adaptation problem scale. These measures were administered at baseline and upon completion of the intervention. RESULTS: Thirty participants in each group completed the study. The mean differences between the baseline and post-test scores in the experimental group for relocation anxiety (t = 5.15, p < .01) and adaptation (t = -5.57, p < .01) were both significant. Among the participants who tested positive for relocation anxiety at pretest (a mean score > 30.13; 83.3% of the participants), those in the experimental group reported a more significant decrease (p < .05) in relocation anxiety at posttest than their control group peers. Among the participants who tested as having poor adaptation pretest (a mean scores < 45.62; 71.7% of the participants), those in the experimental group reported a more significant improvement (p < .05) in adaptation at posttest than their control group peers. CONCLUSIONS / IMPLICATIONS FOR PRACTICE: The results indicate that the 9-week intervention has the potential to help older people with diabetes improve their relocation anxiety and adaptation. This study may be used as a reference to improve emotional distress among residents of long-term care facilities.

Widowhood and health in late life: does health change before or after widowhood in older Taiwanese men and women?

This study investigated (a) whether significant health changes occur before imminent widowhood and (b) the effects of widowhood on the physical and psychological health of men and women ≥ 50 years old. Generalized estimating equations were used to examine a matched-pair sample of the Taiwanese Elderly. We found that for men, the major effect of widowhood was on psychological health, but that for women, the major effect was on physical health. Psychological health was significantly worse for widowed than for non-widowed women, but not for men. The difference in psychological health between widowed and non-widowed women, however, changed before widowhood.

Addition of Carvedilol to Gastric Variceal Obturation Does Not Decrease Recurrence of Gastric Variceal Bleeding in Patients With Cirrhosis.

BACKGROUND & AIMS: Gastric variceal bleeding (GVB) frequently recurs after hemostasis by gastric variceal obturation (GVO). We performed a multicenter, randomized controlled trial to determine the efficacy of carvedilol plus GVO in secondary prophylaxis of GVB. METHODS: We performed a prospective study of 121 patients with cirrhosis (ages 20-80 years) with GVB proven by endoscopy within 24 hours of bleeding and stable hemodynamics for at least 3 days after initial GVO. Patients were randomly assigned into a group that underwent repeated GVO (n = 61) or a group received repeated GVO plus carvedilol (n = 60). Recurrent GVB, upper gastrointestinal bleeding (UGIB), adverse events, and survival were compared between the groups. RESULTS: GVB recurred in 21 patients (34%) in the group that received repeated GVO and 14 patients (23%) in the group that received repeated GVO plus carvedilol (P = .18). Ascites (relative risk [RR], 2.69; 95% CI, 1.33-5.48; P = .006) and hepatoma (RR, 2.10; 95% CI, 1.03-4.28; P = .04) were associated with recurrent GVB. Twenty-nine patients (48%) in the group that received repeated GVO and 17 patients (28%) in the group that received repeated GVO plus carvedilol had recurrent UGIB (P = .03). Carvedilol (RR, 0.44; 95% CI, 0.24-0.80; P = .007) was associated with reduced risk of UGIB recurrence. Ascites (RR, 3.02; 95% CI, 1.59-5.73; P = .001) and hepatoma (RR, 2.07; 95% CI, 1.10-3.88; P = .02) were associated with recurrent UGIB. A higher proportion of patients in the group that received repeated GVO plus carvedilol (53%) had adverse events than the group that received repeated GVO (15%) (P < .001). Mean survival times were 21 ± 18 months in the group that received repeated GVO vs 25 ± 20 months in the group that received repeated GVO plus carvedilol (P = .30). CONCLUSION: In a randomized controlled trial, we found that addition of carvedilol to GVO did not decrease recurrence of GVB in patients with cirrhosis but was associated with decreased recurrence of UGIB. However, carvedilol plus GVO produced significantly more adverse events. Mean survival times did not differ significantly between groups. ClinicalTrials.gov no: NCT02504723.

Development and cross-validation of a new instrument to measure nurse's positive energy of retention: A methodological study.

AIM: The aim of this study was to develop and psychometrically test a new instrument for measuring nurse's positive energy of retention (NPER). BACKGROUND: 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. DESIGN: Methodological study. METHODS: 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. RESULTS: 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. CONCLUSION: 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. IMPACT: 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.

Gallbladder function predicts subsequent biliary complications in patients with common bile duct stones after endoscopic treatment?

BACKGROUND: In patients with common bile duct stones (CBDS) and intact gallbladder, further management for the gallbladder after the CBDS clearance is still controversial. The relationship between gallbladder motility and the biliary complications were seldom discussed. Our study is to predict the subsequent biliary complications by gallbladder function test using fatty meal sonography (FMS) in patients with CBDS who had been treated by endoscopic retrograde cholangiopancreatography (ERCP). METHODS: Patients with an intact gallbladder and CBDS after endoscopic clearance of bile duct were enrolled. Patients received a fatty meal sonography after liver function returned to normal. The fasting volume, residual volume, and gallbladder ejection fraction (GBEF) in FMS were measured. Relationships of patients' characteristics, gallbladder function and recurrent biliary complication were analyzed. RESULTS: From 2011 to 2014, 118 patients were enrolled; 86 patients had calculus gallbladders, and 32 patients had acalculous gallbladders. After a mean follow- up of 33 months, 23 patients had recurrent biliary complications. Among 86 patients with calculus gallbladder, 15 patients had spontaneous clearance of gallbladder stones; 14 patients received cholecystectomy due to acute cholecystitis or recurrent colic pain with smooth postoperative courses. In the follow up period, six patients died of non-biliary causes. The GBEF is significant reduced in most patients with a calculus gallbladder in spite of stone color. Calculus gallbladder, alcohol drinking and more than one sessions of initial endoscopic treatment were found to be the risk factors of recurrent biliary complication. CONCLUSIONS: Gallbladder motility function was poorer in patients with a calculus gallbladder, but it cannot predict the recurrent biliary complication. Since spontaneous clearance of gallbladder stone may occur, wait and see policy of gallbladder management after endoscopic treatment of CBDS is appropriate, but regular follow- up in those patients with risk factors for recurrence is necessary.

Identifying heterogeneity in the Hawthorne effect on hand hygiene observation: a cohort study of overtly and covertly observed results.

BACKGROUND: Observation and feedback are core strategies of hand hygiene (HH) improvement. Direct overt observation is currently the gold standard method. Observation bias, also known as the Hawthorne effect, is a major disadvantage of this method. Our aim was to examine the variation of the Hawthorne effect on HH observation in different healthcare groups and settings. METHODS: A prospective cohort study was performed in a tertiary teaching hospital during a 15-month period. Up to 38 overt observers (82% nurses) and 93 covert observers (81% medical students) participated in HH observation. The HH events observed overtly were matched for occupation, department, observation time, and location with those observed covertly. The data of matched pairs were then analysed to detect possible Hawthorne effects on different variables. RESULTS: A total of 31,522 HH opportunities were observed (4581 overtly, 26,941 covertly). There were 3047 matched pairs after 1:1 matching of overt and covert observations. The overall HH compliance was higher with overt observation than with covert observation (78% vs. 55%, p < 0.001). The Hawthorne effect was nearly three times larger in nurses (30 percentage points) than in physicians (11 percentage points) and was significantly greater in outpatient clinics (41 percentage points) than in intensive care units (11 percentage points). The magnitude of the Hawthorne effect varied among healthcare worker occupations and observation locations (p values both < 0.001) but not among departments, observation times, or HH indications. CONCLUSIONS: Heterogeneity in the Hawthorne effect may influence the interpretation of overt observations and prevent the correct identification of target populations with poor HH compliance. Therefore, directly observed HH compliance may not be an adequate performance indicator for infection control.

Is endoscopic treatment beneficial in patients with clinically suspicious of common bile duct stones but no obvious filling defects during the ERCP examination?

BACKGROUND: Sometimes, no definite filling defect could be found by cholangiogram (ERC) during the endoscopic retrograde cholangio-pancreatiographic (ERCP) exam; even prior images had evidence of common bile duct stones (CBDS). We aimed in estimating the positive rate of extraction of CBDS who had treated by endoscopic sphincterotomy/endoscopic papillary balloon dilation (EST/EPBD) with negative ERC finding. METHODS: One hundred forty-one patients with clinically suspicious of CBDS but negative ERC, who had received EST/EPBD treatments was enrolled. Potential factors for predicting CBDS, as well as the treatment-related complications were analyzed. RESULTS: Nearly half of the patients with negative ERC, had a positive stone extraction. Only patients with high probability of CBDS were significantly associated with positive stone extraction. Moreover, patients with intermediate probability of CBDS had higher rates of overall complications, including post-ERCP pancreatitis. In addition, no significant difference of post-ERCP pancreatitis was found between EST and EPBD groups in any one group of patients with the same probability of CBDS. CONCLUSIONS: Regarding patients with negative ERC, therapeutic ERCP is beneficial and safe for patients present with high probability of CBDS. Moreover, under the same probability of CBDS, there was no significance difference in post-ERCP pancreatitis between EST and EPBD.

Work stress, occupational burnout and depression levels: a clinical study of paediatric intensive care unit nurses in Taiwan.

AIMS AND OBJECTIVES: This study aimed to examine the relationship between work stress and depression; and investigate the mediating effect of occupational burnout among nurses in paediatric intensive care units. BACKGROUND: The relationships among work stress, occupational burnout and depression level have been explored, neither regarding occupational burnout as the mediating role that causes work stress to induce depression nor considering the paediatric intensive care unit context. DESIGN: A cross-sectional correlational design was conducted. METHODS: One hundred and forty-four female paediatric intensive care unit nurses from seven teaching hospitals in southern Taiwan were recruited as the participants. Data were collected by structured questionnaires including individual demographics, the Nurse Stress Checklist, the Occupational Burnout Inventory and the Taiwan Depression Questionnaire. RESULTS: The results indicated that after controlling for individual demographic variables, the correlations of work stress with occupational burnout, as well as work stress and occupational burnout with depression level were all positive. Furthermore, occupational burnout may exert a partial mediating effect on the relationship between work stress and depression level. CONCLUSION: This study provides information about work stress, occupational burnout and depression level, and their correlations, as well as the mediating role of occupational burnout among paediatric intensive care unit nurses. RELEVANCE TO CLINICAL PRACTICE: It suggests government departments and hospital administrators when formulating interventions to prevent work stress and occupational burnout. These interventions can subsequently prevent episodes of depression in paediatric intensive care unit nurses, thereby providing patients with a safe and high-quality nursing environment.

A comparison study between two discharge planning tools.

OBJECTIVE: The objective was to compare the effectiveness between a systematic assessment tool and a traditional assessment tool for discharge planning. METHODS: This research adopted a two-group comparison study design, and convenience sampling was adopted to recruit patients requiring discharge-planning services at eight wards in a regional teaching hospital in Southern Taiwan. The postdischarge care requirements of two groups of patients were evaluated using a traditional assessment tool and a systematic assessment tool in different implementation periods, respectively. Sixty-eight patients were matched with similar age and with similar activity in daily living index scores to compare the effectiveness of the tools. RESULTS: The systematic assessment tool exhibited higher assessment integrity and placement appropriateness, as well as lower rates of rehospitalization or mortality within discharge 14 days. The two groups exhibited no significant difference in inappropriate hospital days, primary decision-makers' satisfaction, and proportion of referral professionals who meet patient care requirements. However, the differences in three items of satisfaction exhibited moderate-to-large effect sizes, which may be of clinical importance. CONCLUSIONS: To meet the needs of primary decision-makers in a family, enhance their satisfaction, and provide effective discharge-planning services, clinicians should adopt the systematic assessment tool to assess the postdischarge care requirements of a patient, and the hospital should provide relevant facilities to assist in implementing all plans.

Perceived exercise barriers and their associations with regular exercise across three age groups of rural women in Taiwan.

The purposes of the study were to explore the differences in perceived exercise barriers across three age groups of Taiwanese rural women (30-50, 51-70, and >70 years old) and to examine the associations between perceived exercise barriers and regular exercise behavior. A total of 227 women completed the Self-Reported Exercise Behavior and the Perceived Exercise Barrier Scale. Women older than 70 reported higher physical and psychological barriers and lower administrative barriers than did the younger group. Women who did not exercise regularly tended to have a higher perception of exercise barriers.

Pain Affects Clinical Patterns and Treatment Outcomes for Patients With Major Depressive Disorder Taking Fluoxetine.

The aim of the study was to determine whether baseline pain was associated with discernible clinical features and treatment outcomes for patients with major depressive disorder (MDD) receiving 6-week fluoxetine treatment. A total of 131 inpatients with acutely ill MDD were enrolled to receive 20 mg of fluoxetine daily for 6 weeks. Pain was measured by the Short-Form 36 body pain index. Symptom severity, functional impairment, and severity of adverse events were assessed at baseline and again at weeks 1 to 4 and 6 using the 17-item Hamilton Depression Rating Scale, Modified Work and Social Adjustment Scale, and Utvalg for Kliniske Undersogelser Side Effect Rating Scale, respectively. Simple linear regression was employed to examine the clinical variables significantly associated with pain. The generalized estimating equations method was used to analyze the influence of pain on the 17-item Hamilton Depression Rating Scale, Modified Work and Social Adjustment Scale, and Utvalg for Kliniske Undersogelser Side Effect Rating Scale over time. Of the 131 participants, 119 (90.8%) who completed baseline pain measurements and had at least 1 postbaseline assessment were included in the analysis. Patients experiencing greater pain were more likely to have more severe depression, to be at greater risk of suicide, to have functional impairment, to experience stressful life events, and to have poor treatment outcomes. These findings suggest that pain was significantly associated with multiple aspects of patients with MDD. Patients with MDD with higher levels of pain were clinically useful in predicting poor outcomes after acute fluoxetine treatment.
