Visual, sensitive and rapid event-specific detection of genetically modified potato EH92-527-1 by loop-mediated isothermal amplification method.

To date, studies on the application of loop-mediated isothermal amplification (LAMP) in the detection of genetically modified organisms (GMOs) are stably increasing and demonstrates LAMP is a potential and promising method for on spot identification of GMOs. However, little information is known for detection of GM potato events by LAMP. In this report, we developed an optimized and visual LAMP assay with high specificity and sensitivity to rapidly amplify genomic DNA of potato EH92-527-1 within 45 min. The limit of detection of LAMP in our study is 10-fold higher than the conventional PCR. Furthermore, LAMP products can be directly observed via naked eyes by addition of SYBR Green I without gel electrophoresis analysis and PCR-based equipment. Therefore, the LAMP assay developed in this paper provides an efficient, convenient and cost-effective tool for the detection of GM potato EH92-527-1.

Inflammatory bowel disease and its treatment in 2018: Global and Taiwanese status updates.

The global incidence and prevalence of inflammatory bowel disease (IBD) has increased over the last 2-4 decades, likely because of the adoption of a more "western" lifestyle as well as improved detection and awareness, and Taiwan is no exception. To characterize the increasing burden of IBD, we conducted a comprehensive review of IBD in the existing literature. The following parameters were reviewed: background knowledge and current standard care for IBD, including natural history, epidemiology, pathogenesis, diagnosis, monitoring, and treatment. In addition, new imaging modalities and treatment options such as combined positron emission tomography and magnetic resonance enterography, new biologic agents, small-molecule therapy, biosimilar therapeutics, mesenchymal stem cell transplantation, and fecal microbiota transplantation, all of which have been introduced for IBD management, were reviewed. We also used the hospital-based as well as population-based Taiwan National Health Insurance Research Database to assess Taiwan-specific trends for comparison with global trends.

[Self-Supporting Care Model for Older Adults].

Self-supporting care is an emerging concept in the geriatric care system of Taiwan. The traditional care model tends to prioritize aspects such as "safety" and "convenient and effective". For older adult patients, this situation has led to excessive restrictions, enforced bedrest, and the use of adult diapers, which seriously deteriorate quality of life. The present article introduces the development and current status of self-supporting care and international empirical research results from the perspective of holistic care for older adults as well as describes the intervention strategies that are currently used in Taiwan. We look forward to the caregivers of older adults being able to apply self-supporting care in their care settings, which is expected to enhance quality of life and dignity for older adults.

Therapeutic outcomes of combined topical autologous serum eye drops with silicone-hydrogel soft contact lenses in the treatment of corneal persistent epithelial defects: A preliminary study.

PURPOSE: To evaluate the efficacy of the combination of topical 20% autologous serum eye drops (ASEs) and silicone-hydrogel soft contact lenses (SCLs) for the treatment of corneal persistent epithelial defects (PEDs), and to compare the recurrence of epithelial breakdown with or without continuous use of ASEs after silicone-hydrogel SCLs removal. METHODS: We conducted a prospective interventional study of 21 eyes of 21 patients with PEDs treated with combined ASEs and silicone-hydrogel SCLs from September 2014 to August 2015. SCLs were removed after total re-epithelialization and patients were subsequently randomized divided into two groups: (1) with and (2) without continuous use of ASEs for an additional 2 weeks. PEDs healing rate and epithelial defect recurrence were evaluated. RESULTS: PEDs healed in all eyes within 3 weeks. Recurrence was noted in five eyes (50%) in patients without continued use of ASEs for 2weeks after total re-epithelialization and SCLs removal during a 3-month follow-up (odds ratio: 23.0; P<0.05). Recurrent epithelial defects were successfully treated with secondary SCLs application combined with autologous serum use. No adverse events were noted during the entire treatment period. CONCLUSIONS: The combined use of ASEs and silicone-hydrogel SCLs can successfully treat recalcitrant PEDs. Prolonged use of ASEs after total re-epithelialization can decrease recurrence rates.

Patient Preferences versus Family Physicians' Perceptions Regarding the Place of End-of-Life Care and Death: A Nationwide Study in Taiwan.

BACKGROUND: Enabling people to die in their preferred place is important for providing high-quality end-of-life care. OBJECTIVE: The study objective was to explore patients' preferences regarding the place of end-of-life care and death and to compare these preferences with the perceptions of their family physicians. METHODS: This cross-sectional study used stratified random sampling, surveying 400 registered patients and 200 of their family physicians nationwide, with a five-part, structured, self-report questionnaire. RESULTS: Of the selected population, 310 patients (response rate 77.5%) and 169 physicians (response rate 84.5%) responded. Regarding the preferred place for end-of-life care, most of the patients would choose to receive care at home (60.6%) if home care services were available. Additionally, home was the most frequently preferred (66.5%) place of death. The family physicians' survey showed that a higher proportion of physicians selected home as the preferred place for end-of-life care and death (71.6% and 87.2%, respectively). The results of logistic regression analysis showed that patients younger than 50 years of age who believed in Chinese folk religion and who resided in a rural area were more likely to prefer to die at home. CONCLUSIONS: The most commonly preferred place for end-of-life care and death is the patient's home. Establishing a community-based palliative care system should be encouraged to allow more individuals to die in their preferred locations. There were discrepancies in the preferred place of end-of-life care and death between the patients' preferences and their family physicians' perceptions. More effective physician-patient communication regarding end-of-life care is needed.

Predictors of surgical and hearing long-term results for inlay cartilage tympanoplasty.

OBJECTIVE: To determine the prognostic factors that affect surgical and audiologic outcomes in inlay tympanoplasty after long-term follow-up. DESIGN: Case series study. SETTING: Tertiary referral center. PATIENTS: Sixty-two patients who underwent 71 procedures were enrolled in the study. Patient ages ranged from 31 to 87 years (mean [SD] age, 61.2 [12.9] years). Mean (SD) follow-up was 635.7 (284.7) days. The inclusion criteria were (1) inlay cartilage tympanoplasty performed using local anesthesia via a transcanal route, (2) chronic otitis media with stable perforation, and (3) dry ear without middle ear disease. MAIN OUTCOME MEASURES: The success rate and hearing change at the last follow-up visit. RESULTS: The overall success rate was 87.3% at the last visit. Using multivariate analysis, sex, age, size of perforation, side of perforation, and the presence of diabetes mellitus and external auditory canal otomycosis did not affect the success. Smoking was the only independent factor for the prognosis of surgical outcome (odds ratio [OR], 8.16; 95% confidence interval [CI], 1.74-36.89; P < .006). On the other hand, age (OR, 6.62; 95% CI, 1.13-38.47; P = .03) and perforation size (OR, 0.11; 95% CI, 0.10-0.79; P = .03) were independent factors for the prognosis of audiologic outcomes. CONCLUSIONS: The frequency of failure was significantly higher for smokers than for nonsmokers. To quit smoking is highly recommended preoperatively for individuals scheduled for chronic otitis media inlay tympanoplasty intervention. Younger patients and those with larger perforations (>50%) were more likely to benefit from this operation.

[Humanity education in nursing].

Nurses play a pivotal role in caring for people. Since every person is unique, providing holistic care is central to the nursing profession. Rapidly advancing technology and the rise of cost-oriented healthcare management have, nevertheless, changed the nurse-patient dynamic and, created new challenges for the nursing profession. It is believed that cultivating humanism in nursing education can sustain nurses' adherence to patient-centered care amidst rapid changes in the health care system. Humanity education can further help nurses develop deeper insights into their own values and life experiences and, in turn, assist them to deal with life and work-related frustrations more effectively. Through a review of the literature, the authors tried to identify content and strategies central to successful humanity education for nursing students. At the end of this article, some suggestions are proposed for the future development of humanity education within Taiwan's nursing community.

Prognostic significance of parapharyngeal space venous plexus and marrow involvement: potential landmarks of dissemination for stage I-III nasopharyngeal carcinoma.

PURPOSE: To determine whether the parapharyngeal space venous plexus and marrow of the skull base bones are anatomic landmarks of the potential routes for the spread of disease for Stage I-III (American Joint Commission on Cancer 1997 staging system) nasopharyngeal carcinoma (NPC). METHODS AND MATERIALS: A total of 364 patients with NPC were enrolled in this study. The selection criteria were Stage I-III disease and primary radiotherapy at our hospital between 1990 and 2001. All patients had undergone MRI to evaluate the head-and-neck tumors. Patients who had undergone inadequate radiotherapy at a dose of <60 Gy and/or preradiotherapy chemotherapy before the imaging evaluation were excluded from the study. RESULTS: Of the 364 patients treated between 1990 and 2001, 163 (44.8%) had low-risk Stage I-III NPC (without parapharyngeal space extension or T3 disease). The 5-year distant metastasis-free survival rate, with and without adjuvant chemotherapy, was 97% and 96%, respectively. The remaining 201 patients had Stage II-III with parapharyngeal space extension or T3 disease. Their 5-year recurrence-free survival rate, with and without adjuvant chemotherapy, was 76.8% and 53.2% (p = 0.01), respectively. CONCLUSION: Our findings suggest that the risk of distant metastasis in Stage I-III NPC patients without parapharyngeal space extension or T3 disease is extremely low. Invasion into the parapharyngeal space venous plexus and marrow of the skull base bones is associated with distant metastasis, and involvement of these anatomic sites is considered a potential route for hematogenous disease spread in patients with Stage I-III NPC.

Improvement of local control of T3 and T4 nasopharyngeal carcinoma by hyperfractionated radiotherapy and concomitant chemotherapy.

PURPOSE: When the primary tumor of nasopharyngeal carcinoma (NPC) is treated at the base of skull and intracranium with conventional radiotherapy, the result is generally poor. In this report, we investigated whether hyperfractionated radiotherapy (HFRT) and concomitant chemotherapy (CCT) could achieve better local control and survival in NPC patients with T3 and T4 lesions. PATIENTS AND METHODS: Forty-eight patients (11 T3 and 37 T4 NPC) were treated with HFRT and CCT. HFRT was administered at 1.2 Gy per fraction, two fractions per day, Monday-Friday for 62 fractions for a total dose of 74.4 Gy. Concomitant chemotherapy consisting of cis-diamino-dichloroplatinum (CDDP) alone or CDDP and 5-fluorouracil was delivered simultaneously with radiotherapy during Weeks 1 and 6. Adjuvant chemotherapy consisted of CDDP and 5-fluorouracil for 2 to 3 cycles and was given monthly beginning 1 month after completion of radiation. RESULTS: With a median follow-up of 57 months (range: 28-94 months), the 3-year locoregional control rate was 93%, the disease-free survival rate was 71%, and the overall survival rate was 72%. For T4 patients, the 3-year locoregional control rate was 91%, disease-free survival was 62%, and overall survival was 63%. The major acute toxicity was Grade 3 mucositis in 73% and Grade 2 weight loss in 31% of patients. Fifty percent of patients were tube fed. Most patients tolerated the combined modality treatments relatively well; 88% of patients completed their radiation treatment within 8 weeks. CONCLUSION: HFRT and CCT for T3 and T4 NPC were associated with excellent local control and improved survival. The treatment-related toxicity was acceptable and reversible. We would recommend using HFRT with CCT for advanced T-stage NPC if the three-dimensional conformal radiation planning shows a significant portion of the brainstem to be inside the treatment field.
