Aims and objectives: To assess the concurrent validity between logbooks and a single‐item rehabilitation adherence measurement for patients with stroke. Agreement between caregivers and patients and between caregivers and physical therapists regarding a single‐item measurement was investigated, and its predictive validity was explored. Background: Adherence to therapy is a primary determinant of treatment success. There are no standard instruments for measuring rehabilitation adherence available for stroke patients. Design: Prospective longitudinal study. Methods: Seventy‐five patients with stroke were recruited, measured four times and followed for 6 months. The Strengthening the Reporting of Observational Studies in Epidemiology (STROBE) checklist was used to ensure comprehensive reporting. Adherence was documented in logbooks, and single‐item measurements were compared. Predictive validity was explored by assessing associations between adherence levels, self‐care ability and health‐related quality of life. The Spearman's correlation coefficients, weighted kappa, and generalised estimating equations statistics were used to explore the concurrent validity, measurement agreement, and predictive validity, respectively. Results: Logbook records had a fair correlation (rs =.23, p =.04) with the single‐item rehabilitation adherence measurements. There was moderate agreement (kappa = 0.42, p <.001) between caregiver and patient assessments and fair agreement (kappa = 0.29, p =.017) between caregiver and physical therapist assessments of patients' rehabilitation adherence levels. Perfect rehabilitation adherence, based on the logbook and single‐item measurements, predicted better scores for self‐care ability and quality of life than imperfect rehabilitation adherence during 6 months after inclusion. Conclusions: There was fair concurrent validity between logbooks and single‐item rehabilitation adherence measurements and moderate and fair adherence measure agreement between caregivers and patients and caregivers and physical therapists, respectively. Logbooks and single‐item rehabilitation adherence measurements had adequate predictive validity. Relevance to clinical practice: Single‐item rehabilitation adherence measurement is a workable and straightforward method to assess stroke patients' rehabilitation adherence in busy clinical care settings. Caregivers can represent stroke patients regarding their reported rehabilitation adherence. Patient or public contribution: Patients were diagnosed with stroke in the study hospital. Rehabilitation physicians transferred patients to a research nurse who then screened them for the inclusion criteria and invited them and their family caregivers to participate in this study if they met the requirements. We also recruited seven physical therapists responsible for the physical therapy of the study participants. After participants signed informed consent, the research nurse encouraged participants to respond to research questions face to face, including rehabilitation adherence data, daily physical function, and quality of life. Each participant was measured four times at baseline and at 1, 3, and 6 months after inclusion in this study. Physical therapists had to score their patients' rehabilitation adherence levels before discharge. Trial registration details: Not applicable. [ABSTRACT FROM AUTHOR]

Background: Abnormal sleep duration affects recovery in older adults with hip fracture and diabetes mellitus (DM) negatively. However, the predictors of abnormal sleep duration in this population remain unknown. Purpose: This study was designed to explore the predictors of abnormal sleep duration among older adults with hip fracture and DM within 6 months of hospital discharge. Methods: A longitudinal study using secondary data from a randomized controlled trial was implemented. Data on fracture-related factors (diagnosis, surgical methods) were collected from medical charts. Information on the duration of DM, methods of DM control, and diabetes-related peripheral vascular disease was collected by asking simple questions. Diabetic peripheral neuropathy was assessed using the Michigan Neuropathy Screening Instrument. Sleep duration outcomes were determined using data collected from a SenseWear armband. Results: Having more comorbidities (OR = 3.14, p =.04), having undergone open reduction (OR = 2.65, p =.005), having undergone closed reduction with internal fixation (OR = 1.39, p =.04), and having DM (OR = 1.18, p =.01), diabetic peripheral neuropathy (OR = 9.60, p =.02), or diabetic peripheral vascular disease for a longer duration (OR = 15.62, p =.006) were all associated with a higher risk of abnormal sleep duration. Conclusions: The findings indicate that patients with more comorbidities or who had undergone internal fixation, had a long DM history, or had complications are more likely to have abnormal sleep duration. Thus, greater attention should be focused on the sleep duration of diabetic older adults with hip fracture who are affected by these factors to achieve better postoperative recovery.

Internet addiction disorder is a relatively new condition, and the criteria for its diagnosis have been developed only over the last several years. The criteria for Internet addiction remain controversial. We strive to further elucidate the clinical validity of the diagnostic criteria for Internet addiction. To test items of the diagnostic criteria for Internet addiction among adolescents, we conducted a clinical interview study of college students based on longitudinal data on their risky use of the Internet. Forty-one high-risk cases were selected from a 3-year 5-time point longitudinal survey of 716 college freshmen. We examined disputes relevant to symptoms and impairment in the DC-IA-A (Diagnostic Criteria for Internet Addiction among Taiwanese Adolescents). Of the 41 cases, 21 were diagnosed with Internet addiction via a psychiatric interview. In the Internet addiction disorder group, 23.8% of cases had a diagnosis of depression, whereas only 15.0% of the cases in the non-Internet addiction group had a diagnosis of depression. Two major criteria (A8 and A3) had low incidences in these high-risk college students and thus did not help provide a differential diagnosis between the groups. We suggest that A8, 'excessive effort spent on activities necessary to obtain access to the Internet', should be omitted, and that A3, 'tolerance: a marked increase in the duration of Internet use needed to achieve satisfaction', should be modified. A1 and A9 should be discussed regarding their role in the diagnosis of Internet addiction disorder. Additional well-designed studies examining the diagnostic criteria and the relationship between factors are needed. © 2015 S. Karger AG, Basel [ABSTRACT FROM AUTHOR]

Exposures to multiple air pollutants during pregnancy have been associated with the risk of gestational diabetes mellitus (GDM). However, their combined effects are unclear. We aimed to evaluate the combined associations of five air pollutants from pre-pregnancy to the 2nd trimester with GDM. This study included 20,113 participants from the Born in Guangzhou Cohort Study (BIGCS). The inverse distance-weighted models were used to estimate individual air pollutant exposure, namely ozone (O 3), nitrogen dioxide (NO 2), sulfur dioxide (SO 2), particulate matter less than 10 μm in diameter (PM 10), and less than 2.5 μm in diameter (PM 2.5). We estimated stage-specific associations of air pollutants with GDM using generalized estimating equation, and departures from additive joint effects were assessed using the relative excess risk (RERI) and the joint relative risk (JRR). Of the 20,113 participants, 3440 women (17.1%) were diagnosed with GDM. In the adjusted model, increased concentrations of O 3 and SO 2 3–6 months before pregnancy were associated with GDM occurrence, as well as O 3 and PM 10 in the 1st trimester, the adjusted relative risk (95% confident intervals) [RRs (95%CI)] ranged from 1.05 (1.00, 1.09) to 1.21 (1.04, 1.40). The largest JRR for GDM was the combination of SO 2 , NO 2 , and PM 10 in the 1st trimester (JRR = 1.32, 95% CI: 1.10, 1.59). The JRR for O 3 and SO 2 was less than their additive joint effects [RERI = -0.25 (−0.47, −0.04), P for interaction = 0.048]. Associations of air pollutants with GDM differed somewhat by pre-pregnancy BMI and season. This study added new evidence to the current understanding of the combined effects of multiple air pollutants on GDM. Public health strategies were needed to reduce the adverse effects of air pollution exposure on pregnant women. • Air pollutant exposure before pregnancy and in the 1st trimester increased GDM risk. •JRRs of combined exposure were often higher than RRs of single exposure models. •We found an antagonistic effect of O 3 and SO 2 in the 1st trimester on GDM. •Overweight/obese women were more susceptible to O 3 than other women. •Associations of air pollutants with GDM differed by season.

Objectives: While the NCCN guidelines maintain that T4b oral cavity squamous cell carcinoma (OCSCC) should undergo either non-surgical treatments or clinical trials, promising outcomes of T4b OCSCC having surgical excision have been reported. We analyzed and compared the clinical outcomes of Taiwanese patients with pT4a and pT4b OCSCC who had undergone surgical treatment.Methods: From 2011 to 2017, a total of 4031 and 355 patients with first primary pT4a and pT4b OCSCC were identified. A propensity score (PS)-matched analysis of patients (n = 351 each) for pT4a and pT4b tumors was also performed.Results: The 5-year disease-specific and overall survival (DSS/OS) rates were more favorable in patients with pT4a than in those with pT4b OCSCC (64%/55%, p < 0.0001; 55%/43%, p < 0.0001, respectively). Compared with pT4a, those with pT4b tumors had a higher burden of the following risk factors: buccal/retromolar/hard palate subsite, male sex, depth ≥ 10 mm, and positive margins. Before PS matching, multivariable analyses revealed that pT4b tumors (versus pT4a) were an adverse prognosticator for both 5-year DSS and OS (hazard ratios: 1.32 and 1.39, respectively). However, in the PS-matched cohort, no significant differences in 5-year DSS and OS rates were observed between pT4a and pT4b OCSCC (57%/56%, p = 0.4024; 48%/44%, p = 0.1807, respectively) CONCLUSIONS: No significant outcome differences were evident between pT4b and pT4a OCSCC after PS matching. The most plausible hypothesis for the observed survival difference between T4a and T4b tumors is that it was driven by positive margins. We suggest that T4b OCSCC should undergo initial surgical excision if adequate resection is possible. [ABSTRACT FROM AUTHOR]

Abstract: A longitudinal study was conducted to investigate the effects of injury type and discharge placement on mortality, falls, hospital admissions, and changes in activities of daily living (ADLs) over a 12-month period among older fallers. Of 762 community-dwelling people aged 65years or older who visited an emergency department (ED) of a general hospital in Taiwan due to a fall, 273 sustained a hip fracture, 157 had a vertebral fracture, 47 had a distal forearm fracture, 102 had a traumatic brain injury, and 183 had soft-tissue injuries. Results showed that, compared to patients with a soft-tissue injury, those with TBI had significantly higher risks of dying (rate ratio (RR)=3.59) and hospital admissions (RR=3.23) and better improvement in ADLs (1.93 points) at 6months post-injury, and those who sustained a hip fracture (4.26 and 4.41 points), a vertebral fracture (3.81 and 3.83 points), or a distal-forearm fracture (2.80 and 2.80 points) had significantly better improvement in ADLs at 6 and 12months post-injury. Patients discharged to a nursing home had a significantly increased risk of death (RR=2.08) and hospital admission (RR=2.05) than those returning to their usual residence during the first year post-injury. No significant differences in the occurrence of falls during the first post-injury year were found among patients with different injury types or between those with different discharge placements. In conclusion, among the five major fall injury types in older people, TBIs result in the highest risk of death and hospital admissions, while hip and vertebral fractures exhibited the largest improvement during the first year after injury. Additionally, nursing home care may be associated with increased risks of death and hospital admissions than home care. In addition to primary prevention of falls, further research to investigate mechanisms leading to TBIs during a fall is needed to facilitate effective secondary fall-prevention programs for older people.

Objective: To evaluate the association between restless legs syndrome (RLS) and hypertension in men and women based on a community-based cohort of middle-aged and elderly participants.Methods: This cross-sectional observational study enrolled 4080 participants from the Sleep Heart Health study (SHHS). RLS was defined by positive responses on a self-administered questionnaire assessing the four diagnostic criteria, with symptoms occurring at least five times per month and associated with at least moderate distress. Hypertension was defined as SBP ≥140 mmHg, DBP ≥90 mmHg, or current use of antihypertensive medication. Propensity score-matched (PSM) inverse probability treatment weighting (IPTW) analyses and multivariable logistic regression were used to examine the relationship between RLS and hypertension.Results: RLS was present in 6.8% of women (n = 152) and 3.2% of men (n = 59). In the primary cohort analysis, the odds ratio (OR) for hypertension was 1.60 [95% confidence interval (CI) 1.19-2.16, p < 0.001] for participants with RLS compared to those without RLS. In the PSM analyses, the OR for hypertension was 1.66 (95% CI 1.09-2.54, p = 0.019) for participants with RLS compared to those without RLS. In sex subgroup analyses, the association between RLS and hypertension persisted in women. In the PSM cohort, the ORs for hypertension were 1.67 (95% CI 1.01-2.81, p = 0.048) and 1.85 (95% CI 0.75-4.75, p = 0.191) in women and men, respectively. Similar results were found in IPTW cohort.Conclusions: This study revealed a positive association between RLS and hypertension in a community-based population; in sex subgroup analyses, the association persisted in women.

Existing evidence on long-term psychotropic polypharmacy in older people is scarce despite serious safety concerns regarding this issue. This study aims to identify distinct trajectories of longitudinal psychotropic agent use and to examine the association with the risk of mortality and unplanned hospitalization according to distinct trajectories. A retrospective longitudinal cohort study based on data from Taiwan's National Health Insurance Research Database (NHIRD). A population-based study including 39,803 eligible participants aged 65 years or older who were newly prescribed oral psychotropic agents in 2004. We assessed 5 years of monthly consumption of psychotropic agents among eligible participants and used group-based trajectory modeling to identify distinct groups of longitudinal psychotropic use. Cox proportional hazards models were used to examine the association between distinct trajectories of longitudinal psychotropic agent use and subsequent 1- and 3-year unplanned hospitalization and all-cause mortality. Among 39,803 eligible participants, we identified 5 trajectories of longitudinal psychotropic agent use over a 5-year follow-up period: sustained intense (7.1%), moderate increasing (12.1%), decreasing (13.4%), slowly increasing (15.7%), and infrequent users (51.6%). Moderate increasing and sustained intense use were associated with significantly higher risks of unplanned hospitalization [moderate increasing use: hazard ratio [HR] 1.30, 95% confidence interval (CI) 1.18-1.44; sustained intense use: HR 1.40, 95% CI 1.24-1.58] and all-cause mortality (moderate increasing use: HR 1.25, 95% CI 1.09-1.44; sustained intense use: HR 1.32, 95% CI 1.12-1.56) than infrequent use. Similar results were observed at 3 years of follow-up. Older people with moderately increasing and sustained intense use of psychotropic agents over time had higher risks of unplanned hospitalization and mortality. Tracking older people's use of psychotropic agents over time may help to identify individuals at greatest risk of unplanned hospitalization and mortality. [ABSTRACT FROM AUTHOR]

Objective: To evaluate the impacts of statin treatment on the risk of benign prostatic enlargement (BPE) progression in hyperlipidemia patients.Methods: Newly diagnosed hyperlipidemia patients (n = 7961), identified from Taiwan's National Health Insurance Research Database, were divided into four statin cohorts (statin use >365 days, n = 1604; statin use 181-365 days, n = 813; statin use 91-180 days, n = 739; and statin use 31-90 days, n = 713) and one control cohort (cohort that used no statins, n = 4092). Study endpoint was occurrence of BPE progression (BPE diagnosis plus receiving BPE-related medications or surgery). Relative risks of BPE progression in the statin cohorts compared to the control cohort were analyzed.Results: Multivariable Cox proportional hazards regression analyses demonstrated that BPE progression risk in the cohort used statins for >365 days was significantly lower than the control cohort (adjusted hazard ratio: 0.70, 95% confidence interval: 0.58 ∼ 0.85, p < .001). However, BPE progression risks of the other three statin cohorts did not significantly differ from the control cohort. Trend analysis revealed that the effects of statin treatment on decreasing BPE progression risk were significantly related to statin treatment duration (p = .001).Conclusions: Hyperlipidemia patients with long-term statin treatment (more than 365 days) are associated with a reduced risk of BPE progression.

Background. The Traditional Chinese Medicine (TCM) Qi-supplementing therapy has been used widely for treating myasthenia gravis (MG) in China. The purpose of this meta-analysis was to evaluate the efficacy and safety of Qi-supplementing therapy as an adjunctive therapy in MG patients. Methods. Seven electronic databases were searched through June 2016. Randomized controlled trials (RCTs) evaluating the add-on effect of Qi-supplementing therapy in MG patients were included. The outcome measures were the total effective rate, relapse rate, and adverse events. Results. Twenty-three RCTs involving 1,691 MG patients were included. The included studies were of low-to-moderate quality. Meta-analysis showed that Qi-supplementing therapy combined with Western medicine (WM) significantly improved the total response rate and reduced the relapse risk during 6–24 months of follow-up. Subgroup analysis showed that Qi-supplementing therapy only affected the total response rate within the first 6 months of treatment. Moreover, the rate of adverse events was lower with the addition of Qi-supplementing therapy to WM than with WM only. Conclusions. Short-term Qi-supplementing therapy combined with WM appears to be superior to WM for improving the total response rate and reducing the relapse rate. However, more high-quality RCTs are warranted owing to methodological flaws of previous trials. [ABSTRACT FROM AUTHOR]

Abstract: Objective: To evaluate the role of allostatic load (AL), either static or dynamic measurements, in predicting all-cause and cause-specific mortality of older people in Taiwan. Design: A prospective cohort study. Setting: Population-based community study. Participants: One thousand twenty-three community-dwelling older people. Measurements: Allostatic load (calculated by systolic blood pressure, diastolic blood pressure, total cholesterol, high-density lipoprotein cholesterol, triglyceride, glycosylated hemoglobin, fasting glucose, waist-to-hip ratio, body mass index, dehydroepiandrosterone sulfate, insulin-like growth factor-1, 12-hour urine cortisol, 12-hour urine epinephrine, 12-hour urine norepinephrine, 12-hour urine dopamine, white blood cell count, neutrophils, interleukin-6, albumin, creatinine) and all-cause and cause-specific mortality from national death registry. Intervention: None. Results: Adjusted for age and sex, each 1-point increase in AL score was associated with 20% incremental risk of mortality [hazard ratio 1.20, 95% confidence interval (CI) 1.09–1.31]. This association can be extended to cause-specific mortality in both sexes in general. In addition, the higher AL score quintile was significantly associated with higher risk of 10-year all-cause mortality (P < .0001). This association was consistent across different cause-specific mortality (ie, malignant neoplasm (P = .008), cardiometabolic diseases (P < .0001), infectious diseases (P < .0001), respiratory diseases (P < .0001), and others (P = .0002), respectively. Compared with AL score decliners, adjusted for age, sex, and baseline AL score in 2000, participants with fast increase had significantly higher mortality (HR 2.68, 95% CI 1.23–5.84, P = .01). The effect was stronger in men (HR 2.83, 95% CI 1.1–7.29, P = .03 in slow increase; HR 4.06, 95% CI 1.56–10.6, P = .001 in fast increase group), but it was insignificant in female participants. Conclusions: Higher AL score or rapid increase of AL score significantly increased subsequent mortality risk in older adults, either measured statically or dynamically. AL is predictive of 10-year mortality regardless of cause of death, and rapid increase in AL score is associated with higher subsequent mortality. [Copyright &y& Elsevier]

Objectives: The choice of optimal antithrombotic therapy in atrial fibrillation (AF) patients with acute coronary syndrome (ACS) or percutaneous coronary intervention (PCI) remains controversial. The aim of this longitudinal cohort study is to investigate the prescribing pattern of antithrombotic regimen in different cohorts and its subsequent impact. Setting and design: Longitudinal data from the Tri-Service General Hospital-Coronary Heart Disease (TSGH-CHD) registry, between January 2016 and August 2018 was screened. Participants and method: Patients with prior history of nonvalvular AF, who had ACS presentation or underwent PCI were selected, and these patients were divided into cohort 1 and cohort 2, according to the index date of antithrombotic prescription before and after the PIONEER AF-PCI study. Primary and secondary outcomes: The primary safety endpoints were composites of major bleeding and/or clinically relevant non-major bleeding. The secondary efficacy endpoints included the occurrence of all-cause mortality, stroke/systemic embolization, nonfatal myocardial infarction (MI), and >30-days coronary revascularization. Results: A total of 121 patients were included into analysis (cohort 1=35; cohort 2=86). Comparing with cohort 1, the prescription rate of triple antithrombotic therapy (TAT) increased from 17.1 to 38.4%, especially the regimen with dual antiplatelet therapy (DAPT) plus low-dose non-vitamin-K dependent oral anticoagulation (NOAC). However, the prescription rate of dual antithrombotic therapy (DAT) decreased (14.3–10.5%), as well as the prescription rate of DAPT (68.6–51.2%). These changes of antithrombotic prescription across different cohorts were not associated with risk of adverse safety (HR= 0.87; 95% CI, 0.42-1.80, p=0.710) and efficacy outcomes (HR=0.96; 95% CI, 0.40-2.32, p=0.930). Conclusions: Entering the NOAC era, the prescription of TAT increased alongside the decrease in DAT. As the prescription rate of DAPT without anticoagulation remained high, future efforts are mandatory to improve the implementation of guidelines and clinical practice. [ABSTRACT FROM AUTHOR]

Abstract: Objective: To evaluate the outcome of vertebroplasty or kyphoplasty (VK), in comparison with non-VK treatment, among patients hospitalized for first-ever vertebral compression fractures (VCFs). Design: A population-based retrospective cohort study. Setting: Taiwan’ s National Health Insurance claims data. Participants: All individuals aged ≥60 years who were newly discharged after hospitalization for a primary VCF diagnosis. Intervention: Percutaneous vertebroplasty or kyphoplasty. Measurements: Study outcomes were discharge outcome (re-hospitalization within 1 week, 1 month or 6 months, categorized by diagnosis) and the prescription of anti-osteoporosis medication for secondary fracture prevention. Potential selection bias was adjusted by using propensity score matching to select one conservatively treated patient (e.g. lumbar brace, analgesics, or physical therapy) matched to one patient receiving VK. Results: The study cohort consisted of 9238 patients who had been discharged after hospitalization for a first-ever VCF between 2004 and 2007. During the index hospitalization, 1018 patients received VK, compared with 8,220 patients who did not receive VK. Patients receiving percutaneous procedure group had a consistently lower incidence of 7-day re-hospitalization for any of the three outcomes (OR = 0.48; 95% CI: 0.32–0.72). Considering the cause of re-hospitalization separately, the vertebroplasty/kyphoplasty group had a significantly lower risk of 7-day re-hospitalization for fracture-related diagnosis (OR = 0.28, 95% CI: 0.12–0.68) and musculoskeletal diagnosis (OR = 0.08, 95% CI: 0.01–0.88) as well as a significantly lower risk of 1-month re-hospitalization (OR = 0.74; 95% CI: 0.59–0.93). Conclusions: VK may protect patients with VCFs from short-term re-hospitalization and a greater need exists for anti-osteoporosis medication as secondary prevention for this at-risk patient group.

The incidence of primary cardiac lymphoma (PCL) is increasing, but the optimal management approach remains unclear. We assessed the clinical characteristics of a single-centre cohort with the goal of determining the optimal management approach. The treatment outcomes and prognostic factors are reported. All PCL patients were diagnosed via biopsy guided by whole-body imaging (positron emission tomography/computed tomography [PET/CT] and/or contrast-enhanced CT]. Curative therapy involved either surgery or prephase steroids followed by definitive immunochemotherapy, depending on the histological type. The primary outcomes were overall survival (OS) and progression-free survival (PFS); the secondary outcome was the treatment response. Twenty-two PCL patients (14 males, 8 females; age: 59.5 ± 14.7 years [mean ± S.D.]) were histologically confirmed to have diffuse large B-cell lymphoma (DLBCL; n = 17 [77.3%]), fibrin-associated DLBCL (FA-DLBCL) (n = 4 [18.2%]) and Burkitt lymphoma (n = 1 [4.5%]). Seven patients underwent cardiotomy (three for biopsy, four with curative intent). The median and longest follow-up periods were 16.3 and 180.0 months, respectively. The 16 patients who received curative therapy (complete response [CR], n = 15 [93.8%]; partial response [PR], n = 1 [6.2%]) showed better survival than those who did not (5-year OS: 83.0 ± 11.3% vs. 0%; hazard ratio [HR]: 0.025[95% confidence interval, CI: 0.003–0.187], p < 0.001); 5-year PFS: 78.7 ± 11.0% vs. 0%, HR= 0.010[0.001–0.093], p < 0.001). The left ventricular ejection fractions (LVEF) before and after definitive treatment was 63.6 ± 2.4% and 64.6 ± 4.5%, respectively (p = 0.275, power = 0.318). Extrapericardial lesions were associated with poorer survival (5-year OS: 40.0 ± 29.7% vs. 100%, p = 0.027; 5-year PFS:40.0 ± 21.9% vs. 100%, p = 0.010). Whole-body imaging is essential for diagnosis and prognosis. Curative therapy provided reasonable outcomes and survival; extrapericardial lesions were associated with a poorer treatment response.

Background: Achieving a good death is the ultimate goal of palliative medicine. Yet, very few studies have investigated factors affecting improvement in quality of dying. We therefore conducted a study to evaluate these factors in terminally ill Taiwanese cancer patients treated in a multidisciplinary palliative care unit. Methods: We included data from terminally ill patients with cancer admitted to the Hospice and Palliative Care Unit in the National Taiwan University Hospital from 2000 to 2009. Quality of dying was assessed by patients' multidisciplinary team at admission and after death using the Good Death Scale and the Audit Scale. We used multivariable regression to assess the association between patient factors, including gender, age, diagnosis, days of hospitalization, calendar year of admission, Good Death score at admission, and process of care scores for physical care, physician-assessed autonomy, emotional support, communication, continuity of life, and physician-reported rate of closure, with the quality of dying. Results: Multivariate regression analysis identified lower Good Death score at admission, lower age 40-65 years, longer unit length of stay (>7 days), higher physician-assessed autonomy, better physician-assessed emotional support, and better physician-reported rate of closure as positively related (all p<0.0001) with improvement in good death scores. Conclusion: In this study in a Taiwanese palliative care unit; we found that late referral to the unit and low physician-assessed autonomy were key factors negatively affecting quality of dying. Earlier truth-tellling and end-of-life care discussions between physicians and patients might improve the quality of dying in this population. [ABSTRACT FROM AUTHOR]

Abstract: This study attempts to identify factors that influence the success or failure of subclassifying 154 cases of neck lymphoma by ultrasound-guided core needle biopsy (UGCNB). Variables including age, gender, nodal size, cutting needle bore, number of core tissues obtained, presence of nodal necrosis or infarct, fragmentation of the specimens and subclassification of lymphoma were reviewed and statistically analyzed to check if they were related to the success of UGCNB. UGCNB was successful in subclassifying lymphoma in 138 (89.7%) cases, in diagnosing lymphoma in 11 (7.1%) and unsuccessful in diagnosing lymphoma in five (3.2%) cases. No complications were encountered. The factors leading to failure in subclassification included the presence of composite lymphoma (p = 0.001), nodal necrosis or infarct (p = 0.001) and insufficiency or fragmentation of the specimens (p < 0.001). UGCNB is a safe and efficient procedure in subclassifying lymphoma. It may obviate surgical biopsy in 89.7% of cases. (E-mail: ylw0518@adm.cgmh.org.tw ) [Copyright &y& Elsevier]

Existing studies cannot evaluate the time-varying properties of frailty and polypharmacy despite raising concerns about their combined effects in older individuals. This study investigated the longitudinal association between different combined statuses of frailty and polypharmacy on risks of adverse outcomes. Retrospective cohort study. Subjects aged between 65 and 100 years (n = 100,000) were identified from Taiwan's National Health Insurance Research Database. Frailty was categorized into fit, mild, moderate, and severe frailty based on the multimorbidity frailty index. Concomitant use of 5 to 9 and ≥10 chronic medications was considered polypharmacy and excessive polypharmacy. We used generalized estimating equation models to examine the association among 12 groups of combined effects of frailty and polypharmacy and risks of all-cause mortality, all-cause hospitalization, and unplanned hospitalization. Age-stratified analyses were conducted for those aged 65 to 74, 75 to 84, and 85+ years. Compared with fit without polypharmacy, severe frailty with excess polypharmacy was associated with increased risks of adverse outcomes, particularly unplanned hospitalization (adjusted relative risk (aRR): 20.01 [95% confidence interval (CI)] 19.30–20.75). However, the combined effects varied in distinct groups. Within each polypharmacy category, there were dose-response associations between frailty category and adverse outcomes. For instance, within the polypharmacy group, the aRRs of mortality were 1.58 (1.52–1.64), 2.70 (2.60–2.80), 4.62 (4.44–4.82), and 6.81 (6.50–7.13) for the fit and mild, moderate, and severe frailty groups, respectively. By contrast, within each frailty category, the dose-response association between polypharmacy and adverse outcomes was limited to fit and mildly frail people. Age-stratified analyses yielded similar results. Both frailty and polypharmacy modified the risks of mortality and hospital admissions in older people, but the combined effects varied in distinct groups. This study thus highlights the potential to optimize care of older people by capturing the dynamic and combined changes related to frailty and polypharmacy. [ABSTRACT FROM AUTHOR]

Objective: Renal insufficiency may influence the pharmacokinetics of drugs. We have investigated the pharmacokinetic parameters of imrecoxib and its two main metabolites in individuals with osteoarthritis (OA) with normal renal function and renal insufficiency, respectively. Methods: This was a prospective, parallel, open, matched-group study in which 24 subjects were enrolled (renal insufficiency group, n = 12; healthy control group, n = 12). Blood samples of subjects administered 100 mg imrecoxib were collected at different time points and analyzed. Plasma concentrations of imrecoxib and its two metabolites (M1 and M2) were determined by the liquid chromatography-tandem mass spectrometry method, and pharmacokinetic parameters (clearance [CL], apparent volume of distribution [Vd], maximum (or peak) serum concentration [Cmax], amount of time drug is present in serum at Cmax [Tmax], area under the curve [AUC; total drug exposure across time], mean residence time [MRT] and elimination half-life [t1/2]) were calculated. Results: The demographic characteristics of the two groups were not significantly different, with the exception of renal function. The mean Cmax and AUC0-t (AUC from time 0 to the last measurable concentration) of imrecoxib in the renal insufficiency group were 59 and 70%, respectively, of those of the healthy control volunteers with normal renal function, indicating a significant decline in the former group (P < 0. 05). The mean pharmacokinetic parameters of Ml in the renal insufficiency and healthy control groups did not significantly differ. In contrast, the mean Cmax and AUC0-t of M2 in the renal insufficiency group were 233 and 367%, respectively, of those of the normal renal function group, indicating a significant increase in the former group (P < 0.05). The mean CL/F (clearance/bioavailability) of M2 of the renal insufficiency group was 37% of that of the normal renal function group, indicating a notable reduction in the former group (P < 0.05). Conclusion: The exposure of imrecoxib in OA patients with renal insufficiency showed a decline compared to that in healthy subjects. However, in patients with renal insufficiency the exposure of M2 was markedly increased and the CL was noticeably reduced. These results indicate that the dosage of imrecoxib should be reduced appropriately in patients with renal insufficiency. [ABSTRACT FROM AUTHOR]

Unlabelled: The objective of this prospective study was to evaluate both thyroid function in children with Hashimoto's thyroiditis and the necessity of lifetime thyroxine replacement therapy. A total of 47 patients with goiter and positive thyroid auto-antibodies participated in the study. Serum thyroxine and thyrotropin levels and titers of thyroid auto-antibodies were checked regularly throughout the follow-up period. At the beginning of the study, 25 patients were diagnosed as euthyroid, but at the end of the study, 22 patients initially diagnosed with euthyroidism remained euthyroid, while eight patients with subclinical hypothyroidism and three patients with overt hypothyroidism had become euthyroid. Thus, of the 22 patients with thyroid dysfunction at diagnosis, subclinical or overt, 11 became euthyroid during the follow-up period. The effect of thyroxine treatment on thyroid auto-antibody titers was not significant.Conclusion: Our data shows that Hashimoto's thyroiditis in children has a benign course and that thyroid function in one half of the patients with thyroid dysfunction at diagnosis reverts to normal. Careful follow-up of thyroid function is important in order to determine the necessity and timing of thyroxine replacement therapy. [ABSTRACT FROM AUTHOR]

Before launching large clinical trials to confirm the effects of statins in improving outcomes among men with prostate cancer (PC), the most appropriate target patient population and the type of statins need to be clearly identified. A retrospective cohort study was conducted using the Taiwan Cancer Registry of 2008–2014. This study included 5749 men with locally advanced and metastatic PC who received only androgen deprivation therapy (ADT) in the first year after their cancer diagnosis. Statin users were defined as anyone who was prescribed statins for >28 days. An inverse probability of treatment-weighted Cox model was used to estimate the effects of statin use on all-cause mortality and PC-specific mortality (PCSM) while treating the statin status as a time-dependent variable. Overall, 2259 patients died, and 1495 of them died of PC during a median follow-up of 3.6 years from 1 year after their diagnosis. Statin use was associated with significant reductions in all-cause mortality (hazard ratio [HR] = 0.78, 95% confidence interval [CI]: 0.70–0.86) and PCSM (HR = 0.76, 95% CI: 0.68–0.86) for metastatic disease and all-cause mortality (HR = 0.66, 95% CI: 0.54–0.81) for locally advanced disease. Patients who received atorvastatin, pravastatin, rosuvastatin or pitavastatin showed a stronger reduction in mortality than those who received other statins. Benefits of statins were consistently observed in men who received post-diagnostic statins, even in those with high comorbidities or an old age. Our results suggest that only atorvastatin, pravastatin and rosuvastatin were associated with improved survival in advanced PC patients receiving ADT. • Statins are potential candidates for secondary prevention in metastatic prostate cancer. • Atorvastatin, pravastatin, and rosuvastatin demonstrated greater survival benefits than other types of statins.

Background: Antibiotic administration is frequent in terminal patients with cancer, yet the effects on survival are still under debate. Objective: The aim of this study was to examine the status of infection and the benefit/burden of antibiotic administration on the survival of terminal patients with cancer with infection. Design: A prospective observational study. Setting/Subjects: We studied 799 patients with terminal cancer who were admitted to a palliative care unit in Taiwan between January 2008 and the end of April 2010. Survival was calculated from the first day of admission to the day of death in the palliative care unit or under home care. Measurements: A specially designed assessment tool was used daily to evaluate clinical conditions. Afterwards, it was analyzed at different time points in a weekly team meeting. Multivariate Cox proportional hazard analyses were used to examine the benefit/burden of antibiotic administration on survival. Results: Four hundred fifty-five patients were diagnosed as having at least one episode of infection after first admission. A total of 295 of the 378 (78.0%) with infection received antibiotic treatment upon admission. Multivariate Cox proportional hazard analyses showed that antibiotic administration was related to improved survival for patients who were still alive 1 week after admission (hazard ratio: 0.66, 95% confidence interfal [CI]: 0.46-0.95). However, antibiotics would be a hazard to patients' survival if used in the time 2 days prior to death (hazard ratio: 1.54, 95% CI: 1.22-1.94). Conclusions: The results suggest that with good communication between patients, families, and medical staff, withdrawal of antibiotics should be considered if signs of death appear, in order to avoid unnecessary risks. The possible benefit of prolonged survival should be in line with the goal of care, and also take into account preparing the patient for a dignified death. [ABSTRACT FROM AUTHOR]

Background Previous studies have demonstrated that multidisciplinary pre-dialysis education and team care may slow the decline in renal function for chronic kidney disease (CKD). Our study compared clinical outcomes of CKD patients between multidisciplinary care (MDC) and usual care in Taiwan. Methods In this 3-year prospective cohort study from 2008 to 2010, we recruited 1056 CKD subjects, aged 20–80 years, from five hospitals, who received either MDC or usual care, had an estimated glomerular filtration rate (eGFR) <60 mL/min, were matched one to one with the propensity score including gender, age, eGFR and co-morbidity diseases. The MDC team was under-cared based on NKF K/DOQI clinical practice guidelines and the Taiwanese pre-end-stage renal disease (ESRD) care program. The incidence of progression to ESRD (initiation of dialysis) and mortality was compared between two groups. We also monitored blood pressure control, the rate of renal function decline, lipid profile, hematocrit and mineral bone disease control. Results Participants were prone to be male (64.8%) with a mean age of 65.1 years and 33.1 months of mean follow-up. The MDC group had higher prescription rates of angiotensin-converting enzyme inhibitor/angiotensin receptor blocker (ACEI/ARB), phosphate binder, vitamin D3, uric acid lower agents and erythropoietin-stimulating therapy and better control in secondary hyperparathyroidism. The decline of renal function in advanced stage CKD IV and V was also slower in the MDC group (−5.1 versus −7.3 mL/min, P = 0.01). The use of temporary dialysis catheter was higher in the usual care group, and CKD patients under MDC intervention exhibited a greater willingness to choose peritoneal dialysis modality. A Cox regression revealed that the MDC group was associated with a 40% reduction in the risk of hospitalization due to infection, and a 51% reduction in patient mortality, but a 68% increase in the risk of initiation dialysis when compared with the usual care group. Conclusions MDC patients were found to have more effective medication prescription according to K/DOQI guidelines and slower renal function declines in advanced/late-stage CKD. After MDC intervention, CKD patients had a better survival rate and were more likely to initiate renal replacement therapy (RRT) instead of mortality. [ABSTRACT FROM PUBLISHER]

Background: Fatigue is a multidimensional phenomenon that has different meanings according to different societal and cultural settings. This study aims to decipher fatigue in Taiwanese patients with cancer. Methods: We recruited 440 patients with advanced cancer admitted consecutively to the palliative care unit of a major medical center in Taiwan. The data were collected at admission, 1 and 2 weeks after admission, and 2 days before death. Results: The subject group consisted of 51.8% males and 48.2% females with a median age of 67 years (ranging from 27 to 93 years). The leading primary tumor sites among these patients were lung (20.2%), liver (18.0%), and colon-rectum (10.7%), and the median survival was 15 days, with a range of 1 to 418 days. All symptoms improved 1 week after admission, but most of them significantly worsened 2 days before death. In general, the physical signs manifested variation patterns similar to those of symptoms. The severity of psychosocial distress and death fear was lower after admission and retained the same level at 2 days before death, defying the consistent patterns found in other symptoms and signs. In the correlation analysis, most symptoms were correlated with fatigue during admission, with weakness being the most significant one. Although self-efficacy and emotion were correlated with fatigue both on admission and 1 week after admission, social support and death fear were not correlated with fatigue at all times. Conclusion: The meaning of fatigue is mainly associated with physical factors among these patients. Education of complexities in fatigue in tandem with psychosocial and spiritual care may help alleviate this symptom, and promote quality of life. [ABSTRACT FROM AUTHOR]

Abstract: Background: A link between the use of alendronate and atypical diaphyseal femoral fracture has been suggested. Objective: The goal of this study was to evaluate the benefits of alendronate in preventing rehospitalization due to hip fractures and whether its use increases risk of hospitalization for atypical diaphyseal femoral fractures in Taiwan. Methods: Using Taiwan''s National Health Insurance database, we identified women with osteoporosis with a first-ever hospitalization for vertebral or hip fractures between 2001 and 2007, which consisted of all patients receiving alendronate, raloxifene, calcitonin salmon, or teriparatide after the index fracture hospitalization. Data of untreated women were obtained as the untreated cohort. Study outcomes were defined as a rehospitalization due to hip fracture or a new hospitalization for subtrochanteric or diaphyseal femoral fracture. Results: Among 11,278 women identified (mean age, 77 years), 2425 (21.5%) received alendronate, 2694 (23.9%) received other antiosteoporosis drugs, and 6159 (54.6%) were untreated. Patients in each group were comparable in fracture history and major comorbidities; untreated patients were more likely to have stroke (11.2%; P = 0.01) and those treated with alendronate were more likely to have a history of hyperlipidemia (16.2%; P = 0.03). Compared with the untreated patient cohort, our analysis suggested that patients prescribed alendronate were associated with decreased risk of rehospitalization due to hip fracture (hazard ratio = 0.67 [95% CI, 0.54–0.82]). Neither patients prescribed alendronate, nor those prescribed other antiosteoporosis drugs, differed significantly from the untreated patient cohort in terms of risk of hospitalization for atypical femoral fracture (adjusted hazard ratios = 0.77 and 0.49 [95% CI, 0.40–1.47 and 0.22–1.12], respectively). Consistent with these data, short- or long-term alendronate use was not found to be significantly associated with higher risk of atypical femoral fractures. Conclusions: This study in Taiwanese patients suggests that alendronate use was associated with a reduction in risk of rehospitalization due to hip fracture. We did not find a significant association between alendronate use and risk of hospitalization for atypical femoral fracture. [Copyright &y& Elsevier]

This study involved longitudinal evaluations of symptom severity and describes the symptom patterns of 77 terminal cancer patients (median age: 62 years; 61% female), selected from 537 consecutive patients admitted to the Palliative Care Unit of the National Taiwan University Hospital. The most common primary cancer sites in these patients were lung (23.4%), liver (15.6%), and stomach (13%). Nineteen physical and psychological symptoms were assessed using different scales. The median number of symptoms was 11 (range: 1–18) on admission, among which weakness, fatigue, anorexia, pain, and depression were the most common. A comparison of the initial symptom severity scores with those at one week after admission and two days before death suggested six symptom change patterns: A: continuous static (restless/heat, abdominal fullness, constipation, dizziness, and insomnia); B: static-increase (fatigue, weakness, nausea/vomiting, taste alteration, dysphagia, diarrhea, dry mouth, and night sweats); C: decrease-static (pain and depression); D: decrease-increase (anorexia and dyspnea); E: static-decrease (aggression); and F: gradually decrease (anxiety). These six symptom patterns can be divided into two categories on the basis of the relative severity of symptoms between one week after admission and two days before death. The first category included patterns A, C, E and F, and the symptoms improved with palliative care. However, the symptoms in the second category (patterns B and D), which were associated with the anorexia-cachexia syndrome and dyspnea, did not show improvement. As symptom management is an essential component of palliative care, holistic care, which encompasses physical, psychosocial and spiritual aspects, represents a rational approach for the relief of these incurable symptoms at the end stage of life for these patients.

Aims Influenza vaccination (InVa) is an effective measure for preventing influenza infection, which is a major cause of morbidity and mortality in older adults. However, the determinants of InVa remain unclear. Methods The present study included 4756 adults aged 55 years and older who completed the baseline examination of the Healthy Aging Longitudinal Study in Taiwan. During the examination, each participant received assessments of InVa status. Comprehensive assessments of sociodemographic (age, sex, education level, marital status, living alone and occupation) and health-related factors (chronic diseases, smoking status, alcohol intake, physical activities, cognitive status and physical performance) were also carried out. The InVa rate was defined as the number of participants who reported receiving free InVa divided by the total number of candidates for free InVa. Multinomial logistic regression analysis was applied to investigate the sociodemographic and health-related determinants of InVa status. Results The coverage rate of InVa was 44.8% (2130/4756). Older age (adjusted odds ratio [OR; >75 years vs <65 years] 7.72, 95% CI 6.26-9.52), multiple chronic diseases (OR [≥2 vs 0)] 1.31, 95% CI 1.10-1.65) and physical activity (OR [yes vs no] 1.43, 95% CI 1.23-1.64) were positively associated with receiving InVa. A current smoking status (OR 0.67, 95% CI 0.55-0.82) was negatively associated with receiving InVa. Conclusions Older adults who received InVa differed from non-receivers in multiple sociodemographic and health-related characteristics. These findings support continual efforts to improve the InVa coverage rate in vulnerable populations. Geriatr Gerontol Int 2017; 17: 2396-2402. [ABSTRACT FROM AUTHOR]

Background: Nursing professionals have received comprehensive medical education and training. However, whether these medical professionals exhibit positive patient care attitudes and behaviors and thus reduce mortality risks when they themselves are diagnosed with chronic diseases is worth exploring. This study compared the mortality risks of female nurses and general patients with diabetes and elucidated factors that caused this difference.Methods: A total of 510,058 female patients newly diagnosed with diabetes between 1998 and 2006 as recorded in the National Health Insurance Research Database were the participants in this study. Nurses with diabetes and general population with diabetes were matched with propensity score method in a 1:10 ratio. The participants were tracked from the date of diagnosis to 2009. The Cox proportional hazards model was utilized to compare the mortality risks in the two groups.Results: Nurses were newly diagnosed with diabetes at a younger age compared with the general public (42.01 ± 12.03 y vs. 59.29 ± 13.11 y). Nevertheless, the matching results showed that nurses had lower mortality risks (HR: 0.53, 95 % CI: 0.38-0.74) and nurses with diabetes in the < 35 and 35-44 age groups exhibited significantly lower mortality risks compared with general patients (HR: 0.23 and 0.36). A further analysis indicated that the factors that influenced the mortality risks of nurses with diabetes included age, catastrophic illnesses, and the severity of diabetes complications.Conclusion: Nurses with diabetes exhibited lower mortality risks possibly because they had received comprehensive medical education and training, may had more knowledge regarding chronic disease control and change their lifestyles. The results can serve as a reference for developing heath education, and for preventing occupational hazards in nurses. [ABSTRACT FROM AUTHOR]

Background: Diabetes is one of the most common chronic illnesses worldwide. This study was to assess whether the incidence risk of type 2 diabetes mellitus between female nurses and female non-nurses.Methods: Study data were obtained from the Longitudinal Health Insurance Research Database, and nurses were sampled from the Registry for medical personnel. Nurses and non-nurses with similar traits and health conditions were selected via 1:1 propensity score matching. A total of 111,670 subjects were selected (55,835 nurses and 55,835 non-nurses). Stages of diabetes development were monitored until December 31, 2009. The Cox proportional hazards model was used to discuss risks and influencing factors related to diabetes. Poisson distribution methods were used to examine the incidence rate of diabetes per 1,000 person-years.Results: The propensity matching results show that on average, female nurses who were diagnosed with diabetes were younger compared with the non-nurses (46.98 ± 10.80 vs. 48.31 ± 10.43, p <0.05). However, the results of the Cox proportional hazards model show that the nurses showed a lower risk of developing diabetes compared with the non-nurses (Adj. HR = 0.84, 95 % CI: 0.79-0.90). Factors influencing diabetes development risks among the nurses include advanced age and high Charlson Comorbidity Index levels.Conclusion: The low degree of diabetes development among the nurses may be attributable to the fact that nurses possess substantial knowledge on health care and on healthy behaviors. The results of this study can be used as a reference to assess occupational risks facing nursing staff, to prevent diabetes development, and to promote health education. [ABSTRACT FROM AUTHOR]
