Translation and adaptation of Shared Care Instrument-Revised for the older adults and their caregivers in Taiwan.

BACKGROUND: The aging population in Taiwan has resulted in an increase in the dependent population and the care load on caregivers. Shared care is an interpersonal process in which support is "traded" to "handle" chronic illnesses by home-care patients and family caregivers. The scale of shared care has received little attention in the Taiwanese cultural context. Thus, this study examined the reliability and validity of the Taiwanese versions of Shared Care Instrument-Revised (SCI-R). METHODS: The content validity, construct validity, and discriminant validity were used to test the validity of the translated questionnaires. The Cronbach's α was used to examine reliability. A total of 500 older adults and their caregivers were recruited from three counties in Taiwan. RESULTS: The reliability and validity of the Chinese version of the scale were within the acceptable range. The Cronbach's α was between 0.838 and 0.95. However, the scale's reliability was higher than that of the original version. This might be because of the inclusion of participants with less severe diseases than the participants in the original study, high social expectations in the Chinese traditional culture, and a large number of similar items. Future research should simplify the items and consider adopting diverse participant selection criteria. CONCLUSIONS: The results of this study can be used to understand shared care in Taiwan.

Effects of user experiences on continuance intention of using immersive three-dimensional virtual reality among institutionalized older adults.

AIM: To evaluate the acceptance of three-dimensional virtual reality programs and to explore the factors influencing the acceptance of the programs among the institutionalized older adults. DESIGN: A cross-sectional explanatory study. METHODS: A total of 71 residents completed the program successfully. They were invited to join a 9-week program included eight activities related to horticultural therapy in a virtual environment. Data were collected by structured questionnaires from August 2018 to February 2019. Ten association hypotheses were derived from the literature review. Partial least squares structural equation modelling was used to examine the proposed hypotheses. RESULTS: Program acceptance was defined as virtual reality practices and continuous usage intention. Frequency of practice was about 12 times during 9-week free-trial period, and the score of continuance usage intention was 13.06 (maximum value of 15). The findings indicated that virtual reality practices were significantly affected by presence and the presence was significantly affected by involvement and interactivity. Continuance usage intention was significantly affected by involvement; and involvement was significantly affected by interactivity. However, continuance usage intention was not significantly influenced by virtual reality practices. CONCLUSIONS: The findings supported that immersive three-dimensional virtual reality program was accepted by the institutionalized older adults. The acceptance, in terms of virtual reality practices and continuous usage intention, was influenced by different paths. The findings have a potential impact on the design of virtual reality technology for the care of institutionalized older adults. IMPACT: What problem did the study address? There were controversial findings about the acceptance of immersive 3D virtual reality program among older adults. What were the main findings? Interactivity advanced the sense of presence and, thus, resulted in a higher frequency of virtual reality practices. Interactivity enhanced perception of involvement, thus, contributing to an increased intention of continuous usage Where and on whom will the research have an impact? The immersive 3D virtual reality program was appropriate for older adults, even for first time users or individuals aged over 80 years. The findings revealed new insights for developing immersive 3D virtual reality programs for the older adults.

Determining delayed admission to intensive care unit for mechanically ventilated patients in the emergency department.

INTRODUCTION: The adverse effects of delayed admission to the intensive care unit (ICU) have been recognized in previous studies. However, the definitions of delayed admission varies across studies. This study proposed a model to define "delayed admission", and explored the effect of ICU-waiting time on patients' outcome. METHODS: This retrospective cohort study included non-traumatic adult patients on mechanical ventilation in the emergency department (ED), from July 2009 to June 2010. The primary outcomes measures were 21-ventilator-day mortality and prolonged hospital stays (over 30 days). Models of Cox regression and logistic regression were used for multivariate analysis. The non-delayed ICU-waiting was defined as a period in which the time effect on mortality was not statistically significant in a Cox regression model. To identify a suitable cut-off point between "delayed" and "non-delayed", subsets from the overall data were made based on ICU-waiting time and the hazard ratio of ICU-waiting hour in each subset was iteratively calculated. The cut-off time was then used to evaluate the impact of delayed ICU admission on mortality and prolonged length of hospital stay. RESULTS: The final analysis included 1,242 patients. The time effect on mortality emerged after 4 hours, thus we deduced ICU-waiting time in ED > 4 hours as delayed. By logistic regression analysis, delayed ICU admission affected the outcomes of 21 ventilator-days mortality and prolonged hospital stay, with odds ratio of 1.41 (95% confidence interval, 1.05 to 1.89) and 1.56 (95% confidence interval, 1.07 to 2.27) respectively. CONCLUSIONS: For patients on mechanical ventilation at the ED, delayed ICU admission is associated with higher probability of mortality and additional resource expenditure. A benchmark waiting time of no more than 4 hours for ICU admission is recommended.

Relationships among Constitution, Stress, and Discomfort in the First Trimester.

The purpose of this study was to explore correlations among constitution, stress, and discomfort symptoms during the first trimester of pregnancy. We adopted a descriptive and correlational research design and collected data from 261 pregnant women during their first trimester in southern Taiwan using structured questionnaires. Results showed that (1) stress was significantly and positively correlated with Yang-Xu, Yin-Xu, and Tan-Shi-Yu-Zhi constitutions, respectively; (2) Yin-Xu and Tan-Shi-Yu-Zhi constitutions had significant correlations with all symptoms of discomfort, while Yang-Xu had significant correlations with all symptoms of discomfort except for "running nose"; (3) Tan-Shi-Yu-Zhi constitution and stress were two indicators for "fatigue"; Tan-Shi-Yu-Zhi was the indicator for "nausea"; Yang-Xu and Yin-Xu were indicators for "frequent urination." Our findings also indicate that stress level affects constitutional changes and that stress and constitutional change affect the incidence of discomfort. This research can help healthcare professionals observe these discomforts and provide individualized care for pregnant women, to nurture pregnant women into neutral-type constitution, minimize their levels of discomfort, and promote the health of the fetus and the mother.

Medical care-seeking patterns among women with menstrual syndromes-related diagnoses: a longitudinal population-based study.

BACKGROUND: Many women experience menstruation-related health issues during their child-bearing years. This study aimed to evaluate women's tendency to seek Traditional Chinese Medicine (TCM) and/or Western Medicine (WM) when newly diagnosed with menstrual syndromes and to identify factors associated with their medical care-seeking behaviors. METHODS: The data of a total of 47,097 women aged between 15 and 50 years with newly diagnosed menstrual syndromes in 2005 were extracted from the Taiwan National Health Insurance Database. The follow-up period was divided equally into 6 month segments over 5 years starting with patients' first visit for obstetric/gynecologic care. Outcomes were outpatient visits and number of TCM or WM visits during each period. Patients' tendency for medical care utilization was estimated using Poisson regression analysis. RESULTS: Number of outpatient visits using TCM was 0.62 (29187/47097), and using WM was 1.67 (78697/47097) within 6 months after the first menstrual syndrome diagnosis. The tendency for TCM utilization increased as follow-up time increased after controlling for potential confounders, while WM utilization decreased as follow-up time increased. Age, economic status, infertility, value of prevention, baby delivery, and obstetric/gynecologic inpatient histories were significantly associated with patients' medical care-seeking behaviors. CONCLUSIONS: TCM and WM medical care-seeking patterns are significantly different among women with diagnoses associated with menstrual syndromes. Related factors affecting medical care-seeking behavior include age, economic status, infertility, value of prevention, childbirth and Ob/Gyn inpatient histories.

Whole genome expression in peripheral-blood samples of workers professionally exposed to polycyclic aromatic hydrocarbons.

This study aims to examine global gene expression profiles before and after the work-shift among coke-oven workers (COWs). COWs work six consecutive days and then take two days off. Two blood and urine samples in each worker were collected before starting to work after two days off and end-of-shift in the sixth day of work in 2009. Altered gene expressions (ratio of gene expression levels between end-of-shift and preshift work) were performed by a Human OneArray expression system which probes ~30,000-transcription expression profiling of human genes. Sixteen workers, all men, were enrolled in this study. Median urinary 1-hydroxypyrene (1OHP) levels (µmol/mol creatinine) in end-of-shift work were significantly higher than those in preshift work (2.58 vs 0.29, p = 0.0002). Among the 20,341 genes which passed experimental quality control, 26 gene expression changes, 7 positive and 19 negative, were highly correlated with across-the-shift urinary 1OHP levels (end-of-shift-preshift 1OHP) (p-value <0.001). The high and low exposure groups of across-the-shift urinary 1OHP levels dichotomized in ~2.00 µmol/mol creatinine were able to be distinguished by these 26 genes. Some of them are known to be involved in apoptosis, chromosome stability/DNA repair, cell cycle control/tumor suppressor, cell adhesion, development/spermatogenesis, immune function, and neuronal cell function. These findings in COWs will be an ideal model to study the relationship of PAH exposure with acute changes of gene expressions.

Acupuncture effects on cardiac functions measured by cardiac magnetic resonance imaging in a feline model.

The usefulness of acupuncture (AP) as a complementary and/or alternative therapy in animals is well established but more research is needed on its clinical efficacy relative to conventional therapy, and on the underlying mechanisms of the effects of AP. Cardiac magnetic resonance imaging (CMRI), an important tool in monitoring cardiovascular diseases, provides a reliable method to monitor the effects of AP on the cardiovascular system. This controlled experiment monitored the effect electro-acupuncture (EA) at bilateral acupoint Neiguan (PC6) on recovery time after ketamine/xylazine cocktail anesthesia in healthy cats. The CMRI data established the basic feline cardiac function index (CFI), including cardiac output and major vessel velocity. To evaluate the effect of EA on the functions of the autonomic nervous and cardiovascular systems, heart rate, respiration rate, electrocardiogram and pulse rate were also measured. Ketamine/xylazine cocktail anesthesia caused a transient hypertension in the cats; EA inhibited this anesthetic-induced hypertension and shortened the post-anesthesia recovery time. Our data support existing knowledge on the cardiovascular benefits of EA at PC6, and also provide strong evidence for the combination of anesthesia and EA to shorten post-anesthesia recovery time and counter the negative effects of anesthetics on cardiac physiology.

Household airborne endotoxin associated with asthma and allergy in elementary school-age children: a case-control study in Kaohsiung, Taiwan.

To evaluate the association between the presence of asthma and allergy, and airborne endotoxin in homes of school-age children in Kaohsiung City, Taiwan, with a case-control study design by matching the age and class exposure. Data collection of home visits included an interviewer-administered questionnaire and air sampling of participants' homes for endotoxin, bacteria, and fungi, as well as temperature and relative humidity measurements. Endotoxin was detected in all air samples with a median value of 0.67 EU m-3. In the adjusted logistic regression model, household airborne endotoxin was associated with higher prevalence of asthma and allergy; OR = 4.88 (95% CI 1.16-20.55) for Q3 (between 0.67 and 1.97 EU m -3) vs. Q1 (< 0.31 EU m -3), with statistical significance. Airborne fungi were associated with higher prevalence of asthma and allergy; OR = 4.47 (95% CI 1.13-17.69) for Q3 (between 314 and 699 CFU m -3) vs. Q1 (< 159 CFU m -3) in adjusted logistic regression models. Airborne endotoxin and fungi were significantly associated with children's asthma and allergy.

Indoor ozone and particulate matter modify the association between airborne endotoxin and schoolchildren's lung function.

BACKGROUND: To date, the effect of household airborne pollutants on the association between airborne endotoxin and lung function of schoolchildren is unknown. OBJECTIVES: The objective of this study is to evaluate whether indoor air pollutants such as carbon monoxide (CO), carbon dioxide (CO2), nitrogen dioxide (NO2), sulfur dioxide (SO2), ozone (O3), particulate matter with aerodynamic diameter <10 and 2.5 µm (PM10, PM2.5) can modify the association between airborne endotoxin and school children's lung function in a heavy industrial city in Taiwan. METHODS: We recruited 120 elementary school-age children in Kaohsiung City, Taiwan. Aerosol samples were collected on a filter membrane for 24 h period and then analyzed for endotoxin. Air pollutants were measured for 24 h in living rooms while school children's lung function was measured. The modification of air pollutants on the relationship between airborne endotoxin and children's lung function was estimated after adjusting the gender, age, height, weight, and case-control status. RESULTS: We found that both O3 and PM10 concentrations significantly modified the relationships between airborne endotoxin and school children's lung function. Among children living in homes with O3 ≥ 0.01 ppm or PM10 ≥ 62 µg/m3, airborne endotoxin was negatively associated with lung functions, whereas among those living in homes with O3 < 0.01 ppm or PM10 < 62 µg/m3, airborne endotoxin was positively associated with lung functions. CONCLUSIONS: The indoor air pollutant concentration of O3 and PM10 modifies the association between airborne endotoxin and school children's lung function.

Pharmacoeconomics of therapy for Guillain-Barré syndrome: plasma exchange and intravenous immunoglobulin.

Guillain-Barré syndrome (GBS) is an acute neuropathy and a clinical syndrome that includes a number of pathological and electrophysiological subtypes. Intravenous immunoglobulin (IVIG) and plasma exchange (PE) are both equally efficacious for the treatment of GBS; however, the cost of IVIG may be lower for both the patient and the healthcare system. To compare the pharmacoeconomics of PE and IVIG in GBS, a retrospective study was done from 1999 to 2004, which included a total of 24 patients with GBS who were admitted to Taipei Veterans General Hospital. This showed that except for the costs of the drugs used in IVIG, treatment of GBS with IVIG was more cost-effective (p=0.057) than that with PE in total length of hospitalization and the cost of procedures and hospitalization. The study also showed that the total costs were higher for patients on ventilators than those not requiring ventilators (p=0.008, t-test) and the length of hospitalization showed a very strong linear relationship to total costs (Pearson correlation coefficient=0.907). The regression analysis showed that each additional day of hospitalization increased the hospitalization costs by an average of 5599 New Taiwan Dollars (NT) (US$1.00=NT$33.50 in 2005).

Time-Lagging Interplay Effect and Excess Risk of Meteorological/Mosquito Parameters and Petrochemical Gas Explosion on Dengue Incidence.

In Kaohsiung, a metropolitan city in Taiwan at high risk of dengue epidemic, weather factors combined with an accidental petrochemical gas explosion (PGE) may affect mosquito‒human dynamics in 2014. Generalized estimating equations with lagged-time Poisson regression analyses were used to evaluate the effect of meteorological/mosquito parameters and PGE on dengue incidences (2000-2014) in Kaohsiung. Increased minimum temperatures rendered a 2- and 3-month lagging interactive effect on higher dengue risks, and higher rainfall exhibited a 1- and 2-month lagging interplay effect on lower risks (interaction, P ≤ 0.001). The dengue risk was significantly higher than that in a large-scale outbreak year (2002) from week 5 after PGE accident in 2014 (2.9‒8.3-fold for weeks 5‒22). The greatest cross-correlation of dengue incidences in the PGE-affected and PGE-neighboring districts was identified at weeks 1 after the PGE (rs = 0.956, P < 0.001). Compared with the reference years, the combined effect of minimum temperature, rainfall, and PGE accounted for 75.1% of excess dengue risk in 2014. In conclusion, time-lagging interplay effects from minimum temperature and rainfall may be respectively associated with early and near environments facilitating dengue transmission. Events that interact with weather and influence mosquito‒human dynamics, such as PGEs, should not be ignored in dengue prevention and control.

Quantitative assessment of efficacy of dysport (botulinum toxin type A) in the treatment of idiopathic blepharospasm and hemifacial spasm.

This study was a Phase IV, prospective, one arm, non-comparative open trial, to investigate the efficacy and safety of Dysport (Botulinum toxin type A) in patients with idiopathic blepharospasm or hemifacial spasm. During the treatment period, patients were evaluated at baseline (week 0), week 6, and week 8, 10, or 12. Thirty two women and 16 men completed the whole course of the study. The therapeutic efficacy of Dysport became evident from 1.5 to 15 days (mean+/- SD, 6.1 +/- 2.9 days). The maximal effect appeared 12.2+/-5.0 days later. Injection of Dysport achieved 72.9 (13.0% amelioration in the spasm symptom. Dysport significantly improved the following functions, such as reading, watching TV, house work, working, driving and outing alone. At the twelfth week after Dysport injection, it was still effective in relieving blepharospasm or hemifacial spasm. The most frequent adverse event was ptosis, which was noted in 9 cases and represented 18.7% of total patients. Other adverse events were very mild, although lagophthalmos and dry eyes occurred in some patients, but none manifested any corneal complications. In conclusion, Dysport injection appears to be a safe, and effective procedure - accompanied only by minor, and transit adverse events.

Prevention of illicit drug use through a school-based program: results of a longitudinal, cluster-randomized controlled trial.

PURPOSE: To evaluate the long-term effects of an illicit drug use prevention program for adolescents that integrates life skills into the theory of planned behavior. METHODS: We conducted a cluster-randomized trial in which 24 participating schools were randomized to either an intervention group (12 schools, n = 1,176 students) or a control group (12 schools, n = 915 students). Participants were grade 7 students. The intervention comprised a main intervention of 10 sessions and two booster interventions. Booster 1 (four sessions) and booster 2 (two sessions) were performed at 6 months and 12 months, respectively, after completion of the main intervention. Assessments were made at baseline, after the main intervention, and after each booster session using specific questionnaires for measuring participants' attitudes, subjective norms, perceived behavioral control, and life skills. RESULTS: Retention rates were 71.9% (845/1,176) in the intervention group and 90.7% (830/915) in the control group after the 12-month follow-up. A significantly lower proportion of intervention group participants reported illicit drug use after the first and second booster sessions compared with control group participants (.1% vs. 1.7% and .2% vs. 1.7%, respectively; both p < .05). Attitudes, subjective norms, perceived behavioral control, life skills, and behavioral intention scores of the intervention group were significantly higher than those of control group after the first and second booster sessions (all p < .001), suggesting that intervention group students tended to avoid drug use. CONCLUSIONS: A drug use prevention program integrating life skills into the theory of planned behavior may be effective for reducing illicit drug use and improving planned behavior-related constructs in adolescents.

Early Statin Use and the Progression of Alzheimer Disease: A Total Population-Based Case-Control Study.

The protective effect of statin on Alzheimer disease (AD) is still controversial, probably due to the debate about when to start the use of statin and the lack of any large-scale randomized evidence that actually supports the hypothesis. The purpose of this study was to examine the protective effect of early statin use on mild-to-moderate AD in the total Taiwanese population.This was a total population-based case-control study, using the total population of Taiwanese citizens seen in general medical practice; therefore, the findings can be applied to the general population. The study patients were those with newly diagnosed dementia (ICD-9 290.x) and prescribed any acetylcholinesterase inhibitors (AChEI) from the Taiwan National Health Insurance dataset in 1997 to 2008. The newly diagnosed eligible mild-to-moderate AD patients were traced from the dates of their index dates, which was defined as the first day to receive any AChEI treatment, back to 1 year (exposure period) to categorize them into AD with early statin use and without early statin use. Early statin use was defined as patients using statin before AChEI treatment. Alzheimer disease patients with early statin use were those receiving any statin treatment during the exposure period. Then, we used propensity-score-matched strategy to match these 2 groups as 1:1. The matched study patients were followed-up from their index dates. The primary outcome was the discontinuation of AChEI treatment, indicating AD progression.There were 719 mild-to-moderate AD-paired patients with early statin use and without early statin use for analyses. Alzheimer disease progression was statistically lower in AD patients with early statin use than those without (P = 0.00054). After adjusting for other covariates, mild-to-moderate AD patients with early stain use exhibited a 0.85-risk (95% CI = 0.76-0.95, P = 0.0066) to have AD progression than those without.Early statin use was significantly associated with a reduction in AD progression in mild-to-moderate AD patients. The future randomized trial studies can confirm our findings.

Traditional Chinese medicine perspective on constitution transformations in perinatal women: A prospective longitudinal study.

BACKGROUND: Pregnancy is an important stage in life for many women. Humans are complex organisms that are prone to exhibiting gradual alterations in their constitutions that fluctuate with age, diet, and living environment. This is particularly true during the pre- and postnatal periods, in which qi and blood are required to ensure foetal growth. AIM: To examine women's constitutional transformation of pre-pregnancy, pregnancy, and postpartum. METHODS: A prospective, longitudinal study was conducted, and structural questionnaires were used to collect data. The participants were healthy pregnant women 21-49 years of age. Data were collected at six times: during the first (weeks 6-13), second (weeks 14-27), and third (weeks 28-40) trimesters and during the postnatal admission (1-week postnatal) and home self-care (6-week and 6-month postnatal) periods, yielding 86 valid questionnaires. A cubic polynomial regression analyses with generalised estimation equations (GEEs) method was used to reveal the trend of constitution score by different constitutions. FINDINGS: Significant differences (p < .0001) for the scores of Yang-Xu (yang-deficiency), Yin-Xu (yin-deficiency), and Tan-Shi-Yu-Zhi (phlegm-dampness and blood-stasis) constitutions were observed at pre-pregnancy, pregnancy, and 6 months postpartum. A least significant difference test showed that the scores obtained in the pregnancy period and at 6 months postpartum were higher than those of pre-pregnancy, indicating mitigated constitutional imbalance during postpartum. The highest scores of the Yang-Xu and Tan-Shi-Yu-Zhi constitutions occurred in the first trimester (36.02 ± 8.00 vs. 30.00 ± 7.21), and the highest scores of Yin-Xu constitution occurred in the third trimester (32.95 ± 7.48). The lowest scores of the Yang-Xu constitution were obtained at 6 months postpartum (25.24 ± 5.63) and during pre-pregnancy (25.26 ± 4.82), and those of the Yin-Xu and Tan-Shi-Yu-Zhi constitutions were observed in the pre-pregnancy (25.48 ± 4.46 vs. 19.94 ± 3.09). The 6-month postnatal scores of the Yang-Xu constitution nearly recovered to the prenatal level, whereas those of the other two constitutions did not. CONCLUSION: The results indicate that women's constitutions underwent changes throughout the perinatal stages. These findings provide a valuable reference for healthcare professionals in administering perinatal care and demonstrate empirical evidence for use in future intervention-based research.

Encephalitis in Taiwan: a prospective hospital-based study.

To investigate encephalitis in Taiwan, a multicenter study was conducted with patients who had acute severe neurological dysfunction and suspected encephalitis from May 2000 to December 2001. Demographic data such as age, sex, and seasons were analyzed. Polymerase chain reaction analyses were performed to determine the microbiologic diagnosis. The patients included 73 males and 54 females, with a peak age of 10-40 years old. Microbiologic diagnoses in 86 (69%) of 124 cases involved herpes simplex virus (HSV, 45 cases), varicella zoster (16 cases), Mycobacterium tuberculosis (10 cases), cytomegalovirus (8 cases), adenovirus (5 cases), influenza (1 case), and enterovirus (1 case). Pathogens were found in 69% of the cases. Encephalitis was most likely to occur in June and July. Based on the results, HSV is still the major viral cause of encephalitis in Taiwan.

Poor responses to interferon-beta treatment in patients with neuromyelitis optica and multiple sclerosis with long spinal cord lesions.

Interferon-beta (IFN-ß) treatment may not be effective in neuromyelitis optica (NMO). Whether the poor response to IFN-ß is related to long spinal cord lesions (LSCL) or the NMO disease entity itself is unclear. We evaluated the spinal cord involvement of patients with multiple sclerosis (MS) and NMO, as well as the response after receiving IFN-ß. Forty-nine MS and 21 NMO patients treated with IFN-ß for at least 2 years from 2002-2008 were enrolled in this study and the treatment response was analyzed 2 years post-treatment. In the study, spinal cord lesions were present in 57.1% (28/49) of the MS patients, of which 16.3% (8/49) presented spinal cord lesions longer than 3 vertebral segments (LSCL). Responses to IFN-ß treatment were seen in 69.3% (34/49) of all the MS cases, of which the appropriate response rates were 76.1% (16/21) in MS patients without spinal cord lesions and 37.5% (3/8) in patients with LSCL. Only 14.2% (3/21) of NMO patients responded to IFN-ß treatment. In conclusion, spinal cord lesion is common in MS patients in Taiwan. Both NMO and MS patients with LSCL had a poor response to IFN-ß treatment. NMO patients had a worse response to IFN-ß treatment than MS patients with LSCL, which shows that the crucial structural defect is something other than LSCL such as the elevated serum IL17 level in NMO compared to MS.

Symptoms of attention deficit hyperactivity disorder and quality of life of mothers of school-aged children: the roles of child, mother, and family variables.

This study examined the impact of inattention and hyperactivity symptoms in children and mothers, opposition problems in children, maternal depression, and perceived family support on the quality of life (QOL) of mothers. Mothers of children in one elementary school were contacted. The relationship between sociodemographic variables, the levels of inattention and hyperactivity symptoms in children and mothers, oppositional symptoms in children, maternal depression, perceived family support, and maternal QOL were examined. Three hundred and eighty-two participants were included in this study. Consistent factors related to the mother's QOL in the four domains were maternal depression, perceived family support, and housing status after controlling for several family, maternal, and child variables. Maternal QOL was more related to her own and family factors including maternal inattention, hyperactivity and depression symptoms, perceived family support, and housing status, instead of parent-rated inattention and hyperactivity symptoms of the child. Screening for maternal inattention, hyperactivity and depression symptoms, and mental health services for these mothers are warranted based on these findings.

Proximal to distal correlates of the patterns of illicit drug use among night school students in Taiwan.

This epidemiological study aimed to investigate illicit drug use by vocational high school night-class students in Taiwan to identify hypothesized proximal and distal factors associated with drug use patterns. Between September 2010 and January 2011, a randomized sample was drawn from 33 vocational high school night classes, enrolling 1079 students already employed outside campus. Subjects completed a validated self-reported questionnaire measuring proximal factors (biological, psychological, and behavioral) and distal factors (living with parents, parents' or siblings' use of legal substances, supervision by primary guardian, and perceived peer influence on drug use). Age, greater sensation-seeking behavior and legal substances use (i.e., tobacco and betel nuts) increased odds of being identified as experimental or regular users versus non-drug users. Higher rates of rule-breaking behavior were associated with increased odds of being identified as experimental users versus non-drug users. Among distal factors, only perceived peer influence on drug use was significantly associated with experimental and regular drug use. Proximal and distal factors were associated with drug use patterns among vocational high school night-class students. Influence factors identified may help vocational high school officials design effective illicit drug intervention programs for students with different drug use patterns.

Predicting mortality of incident dialysis patients in Taiwan--a longitudinal population-based study.

BACKGROUND: Comorbid conditions are highly prevalent among patients with end-stage renal disease (ESRD) and index score is a predictor of mortality in dialysis patients. The aim of this study is to perform a population-based cohort study to investigate the survival rate by age and Charlson comorbidity index (CCI) in incident dialysis patients. METHODS: Using the catastrophic illness registration of the Taiwan National Health Insurance Research Database for all patients from 1 January 1998 to 31 December 2008, individuals newly diagnosed with ESRD and receiving dialysis for more than 90 days were eligible for our study. Individuals younger than 18 years or renal transplantation patients either before or after dialysis were excluded. We calculated the CCI, age-weighted CCI by Deyo-Charlson method according to ICD-9 code and categorized CCI into six groups as index scores <3, 4-6, 7-9, 10-12, 13-15, >15. Cox regression models were used to analyze the association between age, CCI and survival, and the risk markers of survival. RESULTS: There were 79,645 incident dialysis patients, whose mean age (± SD) was 60.96 (±13.92) years; 51.43% of patients were women and 51.2% were diabetic. In cox proportional hazard models and stratifying by age, older patients had significantly higher mortality than younger patients. The mortality risk was higher in persons with higher CCI as compared with low CCI. Mortality increased steadily with higher age or comorbidity both for unadjusted and for adjusted models. For all age groups, mortality rates increased in different CCI groups with the highest rates occurring in the oldest age groups. CONCLUSIONS: Age and CCI are both strong predictors of survival in Taiwan. The older age or higher comorbidity index in incident dialysis patient is associated with lower long-term survival rates. These population-based estimates may assist clinicians who make decisions when patients need long-term dialysis.
