RESUMO
PURPOSE: Limited data exist on asthma medication patterns in Taiwan. The objectives of the SABINA III cross-sectional study in Taiwan were thus, to describe patient demographics and clinical features and estimate short-acting ß2-agonist (SABA) and inhaled corticosteroids (ICS) prescriptions per patient. METHODS: Patients (≥18 years) with asthma were classified by investigator-defined asthma severity per the 2017 Global Initiative for Asthma (GINA) recommendations. Data on asthma symptom control (per GINA 2017 recommendations), severe exacerbation history, and prescribed treatments in the 12 months before study visit were collected using electronic case-report forms. Analyses were descriptive. RESULTS: Overall, all 294 analyzed patients (mean [SD] age, 57.9 [15.6] years; female, 69%) were enrolled by specialists and had fully reimbursed healthcare. Most patients were classified with moderate-to-severe asthma (93.2%; GINA steps 3-5), were obese (53.4%) and nonsmokers (79.6%), reported high school or university and/or postgraduate education (61.9%), and had ≤2 comorbidities (89.1%). Mean (SD) asthma duration was 8.3 (10.0) years, with 37.8% of patients experiencing ≥1 severe exacerbation 12 months before the study visit. Overall, 62.2%, 26.2%, and 11.6% of patients had well-controlled, partly controlled, and uncontrolled asthma, respectively. Crucially, 19.3% of patients were prescribed ≥3 SABA canisters in the preceding 12 months (overprescription). ICS, ICS + long-acting ß2-agonist fixed-dose combination, and oral corticosteroid bursts were prescribed to 6.5%, 97.3%, and 31.6% of patients, respectively. CONCLUSION: Despite treatment by specialists and fully reimbursed healthcare, findings indicate room for improvement in asthma control and SABA prescription practices in Taiwan, emphasizing the need to adhere to latest evidence-based guidelines.

Background: The aetio-pathologenesis of hypertension is multifactorial, encompassing genetic, epigenetic, and environmental factors. The combined effect of genetic and epigenetic changes on hypertension is not known. We evaluated the independent and interactive association of MTHFR rs1801133 single nucleotide polymorphism (SNP) and MTHFR promoter methylation with hypertension among Taiwanese adults. Methods: We retrieved data including, MTHFR promoter methylation, MTHFR rs1801133 genotypes (CC, CT, and TT), basic demography, personal lifestyle habits, and disease history of 1,238 individuals from the Taiwan Biobank (TWB). Results: The distributions of hypertension and MTHFR promoter methylation quartiles (ß < 0.1338, 0.1338 ≤ ß < 0.1385, 0.1385 ≤ ß < 0.1423, and ß ≥ 0.1423 corresponding to
RESUMO
OBJECTIVE: To investigate changes in health-related quality of life (HRQOL) during the first year after injury in elderly Taiwanese women who had fractured a hip, vertebra, distal forearm, or multiple sites. DESIGN: Longitudinal cohort study. SETTING: Personal or telephone interviews of patients from 3 teaching hospitals. PARTICIPANTS: Women (N=347; mean age ± SD, 78.0±6.6y) who had sustained a fracture of the hip, vertebra, or distal forearm due to a fall participated in the baseline assessment, in which both current and prefracture HRQOL data were collected. At 6 and 12 months after the fracture, 285 and 254 women, respectively, completed the follow-up assessments. INTERVENTIONS: Not applicable. MAIN OUTCOME MEASURE: The 4 domains of physical capacity, psychological well-being, social relationships, and environment of the brief version of the World Health Organization Quality of Life questionnaire were assessed. RESULTS: After adjusting for prefracture HRQOL scores and baseline characteristics, women with a hip fracture showed a significant improvement in physical capacity (3.5 points) and a significant decline in social relationships (-3.7 points). Relative to women with a hip fracture at 12 months after injury, those with a vertebral fracture exhibited significantly greater improvement (5.2 points) in physical capacity; those with a distal forearm fracture had significantly greater improvements in physical capacity (11.5 points), psychological well-being (8.4 points), social relationships (7.2 points), and environment (10.9 points), while those with multiple fractures displayed significantly greater improvement in physical capacity (16.5 points), psychological well-being (13.3 points), and environment (10.3 points). CONCLUSIONS: Among the 4 fracture types in elderly women, hip fractures may result in the smallest improvement in the physical domain and the greatest declines in the psychological, social, and environmental domains during the first year. The magnitude of the impact of each fracture type varied across different domains.

Patient outcomes of non-small-cell lung cancer (NSCLC) vary because of tumor heterogeneity and treatment strategies. This study aimed to construct a deep learning model combining both radiomic and clinical features to predict the overall survival of patients with NSCLC. To improve the reliability of the proposed model, radiomic analysis complying with the Image Biomarker Standardization Initiative and the compensation approach to integrate multicenter datasets were performed on contrast-enhanced computed tomography (CECT) images. Pretreatment CECT images and the clinical data of 492 patients with NSCLC from two hospitals were collected. The deep neural network architecture, DeepSurv, with the input of radiomic and clinical features was employed. The performance of survival prediction model was assessed using the C-index and area under the curve (AUC) 8, 12, and 24 months after diagnosis. The performance of survival prediction that combined eight radiomic features and five clinical features outperformed that solely based on radiomic or clinical features. The C-index values of the combined model achieved 0.74, 0.75, and 0.75, respectively, and AUC values of 0.76, 0.74, and 0.73, respectively, 8, 12, and 24 months after diagnosis. In conclusion, combining the traits of pretreatment CECT images, lesion characteristics, and treatment strategies could effectively predict the survival of patients with NSCLC using a deep learning model.
RESUMO
Immunoglobulin E (IgE) and mast cells play important roles in the pathogenesis of allergic asthma. Catalpol, an iridoid glycoside, exerts many biological functions including anti-inflammatory activities. Herein, we investigated catalpol to determine both its antiallergic effects on IgE/ovalbumin (OVA)-stimulated mouse bone marrow-derived mast cells and its therapeutic actions in murine allergic asthma. We found that catalpol dramatically suppressed IgE/OVA-induced mast cell degranulation. Meanwhile, 5 ~ 100 µM of catalpol neither affected the expression level of the high-affinity receptor of IgE (FcεRI) by mast cells nor induced mast cell apoptosis. In addition, mRNA expression levels of inflammatory enzymes including cyclooxygenase (COX)-1, COX-2, and 5-lipoxygenase were downregulated. Administration of catalpol also suppressed production of prostaglandin D2 (PGD2), interleukin (IL)-6, and IL-13, while not affecting tumor necrosis factor (TNF)-α production. Further, catalpol pretreatment significantly attenuated the FcεRI-mediated Akt signaling pathway. In mice with IgE/OVA-induced asthma, oral administration of catalpol remarkably suppressed the production of OVA-specific IgE, the development of airway hyperresponsiveness (AHR), and the infiltration of eosinophils and neutrophils into the lungs. Histological studies demonstrated that catalpol substantially inhibited the recruitment of mast cells and increased mucus production in lung tissues. Catalpol-treated mice had significantly lower levels of helper T cell type 2 (Th2) cytokines (IL-4, IL-5, and IL-13), PGD2, eotaxin-1, and C-X-C chemokine ligand-1 (CXCL1) in bronchoalveolar lavage fluid (BALF) than did the allergic group. Collectively, these results indicated that the suppressive effects of catalpol on degranulation and mediator generation by mast cells were beneficial in treating allergic asthma.

AIM: A nested case-control study was carried out to examine relationships of a fall-risk score and the use of single medications and polypharmacy with falls among hospitalized patients aged 50 years and older in Taiwan. METHODS: There were 83 patients who experienced a fall during hospitalization in an acute-care hospital. Matched by age and sex, five control patients for each case were randomly selected from all other inpatients who had not experienced any fall at the time of the index fall. RESULTS: Patients who took tricyclic antidepressants, diuretics, and narcotics were 3.36-, 1.83- and 2.09-fold, respectively, more likely to experience a fall than their counterparts. Conversely, patients who took beta-blockers were 0.34-fold more likely than those who did not take them to experience a fall. Patients taking ≥6 medications were 3.08-fold more likely than those taking fewer medications to experience a fall, whereas those with anxiety were 4.72-fold more likely to experience a fall than those without. A high fall-risk score was not significantly associated with the occurrence of falls. CONCLUSIONS: Among older hospitalized patients, tricyclic antidepressants, diuretics, narcotics, and polypharmacy should be mindfully prescribed and reviewed on a regular basis. A fall-risk scale developed from community-dwelling older people might not accurately predict falls in hospitalized patients. Further research to validate the negative effect of beta-blocker use on falls is required.

BACKGROUND: Allergic rhinitis (AR) often coexists with and can significantly worsen bronchial asthma (BA). We evaluated the proportion of patients with BA and concomitant AR (BA+AR) diagnosed and treated in an average clinical practice. METHODS: A cross-sectional study methodology was used to determine the prevalence of AR in patients more than 15 years of age with a documented history of asthma who experienced wheezing during the prior 12 months. The International Study of Asthma and Allergies in Childhood standardized written questionnaire was used and therapeutic class choices were recorded. RESULTS: Among 750 surveyed asthma patients, 524 patients (69.9%) experienced AR. Of those with BA and AR, there were 44 patients (8.4%) who were not diagnosed with AR, and the treatment rate for AR was 62.1%. The most frequent severity level of BA and AR were moderate persistent (38.9%) and intermittent mild (52.5%), respectively. There were no significant differences between patients with AR and without AR. CONCLUSIONS: The prevalence of AR in patients with asthma was 69.9% in this study. Despite Allergic Rhinitis and its Impact on Asthma guideline recommendations encouraging evaluation and treatment of AR among asthmatics, nearly 8.4% of asthmatics with AR were undiagnosed, and 37.9% of asthmatics with AR were untreated for AR.
