        Acupuncture for ventilator-dependent patients at a hospital-based respiratory care center: A randomized controlled trial

        Jia-Ming Chen,Wan-Li Chiang,Bin-Chuan Ji,Ruei-Jhe Jhang,Pei-Hsin Chen,Ya-Lun Li,Che-Ju Chang,Sung-Yen Huang,Tsung-Chieh Lee,Chia-Yun Chen,Ching-Hsiung Lin,Sheng-Hao Lin 한국한의학연구원 2023 Integrative Medicine Research Vol.12 No.4

        Background: In intensive care units, mechanical ventilation is an important therapy to help patients with dysp- nea. However, long-term ventilator dependence would consume huge medical resources and increase the risk of morbidity and mortality. The aim of the study was to examine the efficacy of the acupuncture combined with western medical care on ventilator parameters in ventilator-dependent patients. Methods: In this clinical trial, 80 ventilator-dependent patients aged 20 to 80 years old were randomly assigned to acupuncture group and control group in the respiratory care center (RCC) of Changhua Christian Hospital. Besides regular medical care and therapy, participants in the acupuncture group received acupuncture therapy at the same 17 acu-points for 20 minutes once a day, a total of 12 sessions. The ventilator parameters were recorded to evaluate the respiratory efficiency for all participants. The primary outcome was rapid shallow breathing index (RSBI), and secondary outcomes were respiratory rate (RR), tidal volume (TV) and ventilation per minute (MV). Results: Though there was no significant difference in the parameter between the acupuncture group and the control group, we found the trend of decreasing RSBI in the acupuncture group. In subgroup analyses, the mean of RSBI significantly decreased 16.02 (with the SD in 60.84) in acupuncture group, while it increased 17.84 (with the SD in 39.38) in control group (p = 0.036) after 12 sessions. Conclusion: Acupuncture treatment can improve breathing ability of patients with respirator dependence in respiratory care center.

        Experimental investigation of a process cooling system retrofitted with HFC-404A refrigerant for precise manufacturing application

        Fu-Jen Wang,Kuei-I Tsai,Yao-Jun Wang,Hao-Chuan Lee 대한기계학회 2011 JOURNAL OF MECHANICAL SCIENCE AND TECHNOLOGY Vol.25 No.2

        Precise-manufacturing facilities, which emphasize accurate and stable machining of the working components to be used in semiconductor industry, cannot function properly without appropriate and precise cooling. HCFC (hydro-chloro-floro-carbon) has been commonly used as the coolant for precise manufacturing facilities; but it is facing the pressing schedule to be phased out. Additionally, the dramatic variation of heat load during high-accuracy and high-speed applications need a critical control of coolant (brine or water) temperature. Use of eco-friendly HFC 404A to replace HFC has been suggested as an effective alternative to alleviate the problems. In this study, the performance of a process cooling system retrofitted with HFC-404A refrigerant was evaluated; the energy efficiency ratio and accuracy of temperature control specific to -15℃ precise manufacturing application were examined. Effects of using thermostatic expansion valve associated with hot-gas by-pass control scheme under different loading conditions have been investigated extensively. The energy efficiency ratio and accuracy of temperature control for the cooling system were measured and analyzed for comparing and evaluating HCFC-22 and HFC-404A using different throttling devices under specific coolant temperatures. The comprehensive studies on improving the accuracy of temperature control and energy-saving efficiencies through different temperature control strategies are presented in this paper.

      • High Rates of SVR12 in Adolescents Treated with the Combination of Ledipasvir/Sofosbuvir

        ( Kathleen Schwarz ),( Karen F. Murray ),( Philip Rosenthal ),( Sanjay Bansal ),( Chuan-hao Lin ),( Sooji Lee ),( Liyun Ni ),( Bittoo Kanwar ),( Jenna Fraser ),( Polina German ),( Diana M. Brainard ) 대한간학회 2018 춘·추계 학술대회 (KASL) Vol.2018 No.1

        Aims: Although direct acting antivirals have transformed HCV treatment of adults, the standard of care for adolescents and younger children with GT1 HCV is still limited to treatment with pegylated interferon+ribavirin for 48 weeks. The aim of this study was to evaluate the safety, efficacy and pharmacokinetics of the fixed dose single tablet regimen, ledipasvir/sofosbuvir (LDV/SOF), administered for 12weeks in GT1 HCV-infected adolescent patients. Methods: Treatment-naive and treatment-experienced adolescent patients aged 12 to less than 18 years old with chronic GT1 HCV were enrolled into this open-label ongoing study to receive 12 weeks of treatment with LDV/SOF 90mg/400 mg once daily. The primary efficacy endpoint is SVR12 (HCV RNA<lower limit of quantitation). Safety is assessed by clinical evaluation and laboratory monitoring. Intensive pharmacokinetic (PK) sampling was done on Day 10 in the first 10 patients (PK lead-in) to confirm the appropriateness of the adult dose in the adolescent population. Results: 100 GT1 patients have been enrolled and treated. The majority are GT1a (81%), female (63%), white (90%), treatment-naive (80%), and vertically infected (84%). The mean age is 15 (range 12-17) years. In the PK lead-in, administration of 1 tablet daily of LDV/SOF provided comparable plasma exposures of LDV, SOF, and GS-331007 (SOF primary metabolite) to those observed in adults. SVR12 rate was 97% (97/100). 3 patients were lost to follow-up. No serious adverse events (AEs) have been reported. AEs are generally mild in severity and grade 3/4 laboratory abnormalities have been infrequent and transient. Conclusions: The 12-week regimen of LDV/SOF 90mg/400 mg has resulted in high SVR rates and is well-tolerated. This regimen provides a safe and effective therapy for adolescents with GT1 HCV infection. Further evaluation is ongoing in children aged 3-11 years old.
