Effects of a Physically Active Lifestyle Modification (PALM) Program for Independent Taiwanese Older Adults

Topics in Geriatric Rehabilitation (2022)

Chang-Chih Kuo Hui-Jen Shyu Daniel Park Peichun Amy Tsai Yu-Hsien Li

This pilot study investigated a manualized lifestyle-based intervention, Physically Active Lifestyle Modification (PALM) program, designed to increase physical activity in the daily life routines of Taiwanese older adults and improve their quality of life. Thirty older adults who attended a Senior Citizens Learning Camp in Taiwan participated in the program. Quantitative measures and qualitative interviews were employed to study the intervention's effect on quality of life and to capture participants' subjective experiences in the program. Results revealed significant improvement in both physical and mental component summary of the RAND 36-Item Short Form Health Survey. Interview data revealed 4 key themes: change in action, self-awareness of occupational pattern, acquisition of health information, and social participation.

Clinical Outcomes of Laparoscopic Greater Curvature Plication and Laparoscopic Sleeve Gastrectomy: a Case-Matched Control Study

Obesity Surgery (2018)

Yu-Hsien Li Bing‐Yen Wang Yu‐Ching Huang Lien‐Cheng Tsao Chien‐Pin Chan

Laparoscopic greater curvature plication (LGCP) is a new bariatric procedure that is similar to laparoscopic sleeve gastrectomy (LSG) in that it uses a restrictive mechanism. Comparative studies between LGCP and LSG were still limited. The aim of this study was to compare the clinical outcomes of the two procedures based on the same clinical conditions. From January 2012 to December 2015, 260 patients with morbid obesity underwent LGCP and LSG in a single center. Data on patient demography, operation time, complications, hospital stay, body mass index loss, percentage of excess weight loss (%EWL), and improvement in comorbidities were collected. A propensity-matched analysis, incorporating pre-operative variables, was used to compare the short-term outcomes between LGCP and LSG. Propensity matching produced 48 patients in each group. Patients who underwent LGCP were predominately female (75.5%, 41.1% of the LSG patients were female, p = 0.028). Baseline BMI and excess weight were significantly lower in the LGCP group (p < 0.001). The LSG group showed a greater decrease in excess body weight than the LGCP group (LSG, 47.36 ± 12.95% in 3 months, 57.97 ± 19.28% in 6 months, 66.28 ± 25.42% in 12 months; LGCP, 39.67 ± 12.58% in 3 months, 47.40 ± 19.30% in 6 months, 48.02 ± 20.17% in 12 months, p = 0.008, 0.032, 0.010). Perioperative complications and resolution of obesity-related comorbidities were not significantly different between the two groups. LGCP and LSG are both feasible and safe procedures for surgical weight reduction. In short-term follow-ups, LSG demonstrates a better excess body weight reduction while having perioperative complications similar to LGCP.

Miniature osmotic actuators for controlled maxillofacial distraction osteogenesis

Journal of Micromechanics and Microengineering (2010)

Yu-Hsien Li Yu-Chuan Su

We have successfully demonstrated miniature actuators that are capable of converting chemical potential directly into steady mechanical movements for maxillofacial distraction osteogenesis. Pistons and diaphragms powered by osmosis are employed to provide the desired linear and volumetric displacements for bone distraction and potentially the release of bone morphogenetic proteins, respectively. The cylindrical-shaped miniature actuators are composed of polymeric materials and fabricated by molding and assembly processes. In the prototype demonstration, vapor-permeable thermoplastic polyurethane was employed as the semi-permeable material. 3 cm long actuators with piston and diaphragm radii of 1 mm and 500 µm, respectively, were fabricated and characterized. The maximum distraction force from the piston-type actuator is found to be 6 N while the piston travels at a constant velocity of 32 µm h−1 (or 0.77 mm/day) for about 1 week. Meanwhile, the release rate from the diaphragm-type actuator is measured to be constant, 0.15 µl h−1 (or 3.6 µl/day), throughout the experiment. Moreover, the sizes and output characteristics of the self-regulating actuators could readily be tailored to realize optimal distraction rate, rhythm and osteogenic activity. As such, the demonstrated miniature osmotic actuators could potentially serve as versatile apparatuses for maxillofacial distraction osteogenesis and fulfill the needs of a variety of implantable and biomedical applications.

Can Deep Neural Networks Outperform Fama-MacBeth Regression and Other Supervised Learning Approaches in Stock Returns Prediction With Asset-Pricing Factors?

SSRN Electronic Journal (2022)

Huei-Wen Teng Yu-Hsien Li

In asset pricing, most studies focus on finding new factors such as macroeconomic factors or firm characteristics to explain risk premium. Investigating whether these factors are useful in forecasting stock returns remains active research in the field of finance and computer science. This paper conducts an extensive comparative analysis using a large set of pricing factors and compares out-of-sample stock-level and portfolio-level prediction performance among neural networks, the traditional Fama-MacBeth regression, and other supervised learning algorithms such as regression and tree-based algorithms. Our analysis shows the benefit of employing neural networks, and deeper neural networks enjoy marginal improvements in terms of prediction.

Unusual association of Axenfeld-Rieger syndrome and wandering spleen: a case report

Research Square (Research Square) (2020)

Joseph Lin Yi-Lin Chang Yu-Hsien Li Lien‐Cheng Tsao

Abstract Background : Axenfeld–Rieger syndrome (ARS) is an autosomal dominant genetic disease characterized by ocular developmental disorders and it’s association with torsion of wandering spleen (WS) has not been reported to date to the best of our knowledge. This study aimed to describe a rare case of ARS observed at our emergency department. Case Presentation : A 25-year-old female presented with a constant lower abdominal pain of increasing severity. Diagnostic computed tomography with intravenous contrast material showed a nonhomogenously enhanced splenic parenchyma with a twisted vascular pedicle. Further, an emergent laparoscopic exploration was performed, and an ischemic spleen without its normal ligamentous attachments was noted. Notably, the spleen did not regain its normal vascularity after detorsion; thus, we performed the laparoscopic splenectomy. The postoperative course was uneventful, and the patient was discharged on the 5 th postoperative day. This case demonstrates a rare association of WS and ARS. Conclusion : Early diagnosis of WS in the emergency department is important to prevent pedicle torsion or splenic necrosis and to avoid splenectomy.

Further, an emergent laparoscopic exploration was performed, and an ischemic spleen without its normal ligamentous attachments was noted. Notably, the spleen did not regain its normal vascularity after detorsion; thus, we performed the laparoscopic total splenectomy. The postoperative course was uneventful, and the patient was discharged on the 5th postoperative day. This case demonstrates a rare association of WS and ARS.Early diagnosis of WS in the emergency department is important to prevent pedicle torsion or splenic necrosis and to avoid splenectomy.

An 85 dB SNDR third-order ΔΣ modulator for audio applications

2022 IEEE/SICE International Symposium on System Integration (SII) (2017)

Szu-Ning Ting Ro‐Min Weng Sheng-Yu Peng Tzu-Yun Wang Yu-Hsien Li

A 1.8 V 1 mW single-loop third-order delta sigma modulator is presented for audio applications, which achieves 85.1 dB SNDR in 20 kHz signal bandwidth with a sampling frequency of 5.12 MHz. The modulator is implemented by using the fully differential switched-capacitor circuit to compose a discrete-time system. The cascade of integrators with feedforward summation architecture is used to reduce the performance of the amplifier, so the amplifier is enabled to decrease the power dissipation. By considering the characteristics of the modulator, an operational amplifier is designed with low-quiescent current. The chip is implemented in a standard 0.18-μm CMOS process with the area of 0.24-mm ² .
