Summary Background & aims In dialysis patients, malnutrition is a poor prognostic factor. In patients with chronic kidney disease (CKD), malnutrition is qualitatively different from general malnutrition, which is defined as “Protein-Energy Wasting (PEW).” Dietary therapy for the enhancement of PEW requires the aggressive intake of protein. Conversely, as protein intake and phosphorus intake correlate positively, increasing the protein intake increases the phosphorus intake, which is a poor progn...

Introduction : The number of patients who undergo laparoscopic sleeve gastrectomy (LSG) has been increasing. Department of Surgery, Tokushima University performed the first LSG in 2013. The aim of this study was to report the results of the initial ten cases who underwent a LSG. Patients and methods : Ten obese patients : five males and five females ; age range from thirty-three years to fifty-six years (mean age 42.2 years) ; mean body mass index (BMI) 50.3 ; five with diabetes ; nine with hype...

Chronic care patients undergoing hemodialysis for treatment of end-stage renal failure experience higher rates of bloodstream-associated infection due to the patients' compromised immune system and management of the bloodstream through catheters. Staphylococcus species are a common cause of hemodialysis catheter-related bloodstream infections. We investigated environmental bacterial contamination of dialysis wards and contamination of hemodialysis devices to determine the source of bacteria for ...

Abstract This study develop the solar tracking system of a nonelectric power source by using a metal hydride (MH) actuator with solar radiation drive. The proposed tracking system includes two MH reactors of the same shape that are placed perpendicular to the solar cell array. A shielding plate is installed between the MH reactors to interrupt the solar radiation from each MH reactor. The solar angle of direction changes when there is a temperature difference between the MH reactors. This is bec...

Abstract This study is based on labor intensive factory, located in Dhaka, Bangladesh which was adversely impacted due to extreme hot conditions. The analysis started with the implementation of green roof (GR) as one of the passive design strategies to reduce indoor heat stress. Impact of indoor heat stress indicated by wet bulb globe temperature (WBGT) and prediction of heat strain (PHS) model for green roof have been evaluated through numerical studies and indoor environmental data of local fa...

Abstract From field monitoring, it has been observed that in readymade garments (RMG) production spaces, thousands of workers have been worked day long and might have probability of different thermal perceptions. As thermal comfort is the crucial phenomenon for workers, for the reduction of excessive indoor heat, using HVAC cooling strategies are the most critical segments in energy consumption. This paper describes an experimental study about assessment of different indoor environmental steps t...

Serum transthyretin (TTR), also known as prealbumin, is a reliable nutritional indicator and an independent prognostic factor for maintenance hemodialysis patients. However, we recently reported that serum TTR levels did not affect protein−energy wasting (PEW). In this study, we investigated factors affecting serum TTR levels in 60 maintenance hemodialysis patients. The patients were divided into High-TTR and Low-TTR groups according to the median serum TTR level. Albumin levels were significant...
