Hip fracture, which is associated with substantial morbidity and long-term mortality, imposes a major burden on the healthcare system. Diabetes is a risk factor for osteoporosis, which is a crucial risk factor of hip fracture. However, epidemiological studies investigating the risk of hip fracture among patients with type 2 diabetes are limited. This study(More)
Splenectomy may be necessary to treat systemic lupus erythematosus (SLE) patients with thrombocytopenia; however, whether performing a splenectomy on patients without SLE increases the subsequent risk of SLE remains unknown. Therefore, this study was conducted to determine the association between splenectomy and SLE. We conducted a cohort study by using(More)

Energy harvesting (EH) can be used in wireless sensor networks (WSNs) since the sensors can be powered by ambient energy in conjunction with rechargeable batteries to achieve near-perpetual operation [1-4]. One common solution is to harvest energy from ambient light through photovoltaic (PV) modules. In such a system, a battery supplements energy when the(More)
This study aimed to examine whether poor glycemic control, measured by glycated hemoglobin A1C (HbA1c) and other cardiovascular risk factors, can predict diabetic peripheral neuropathy (DPN) in patients with type 2 diabetes mellitus (DM).Patients aged ≥30 years with type 2 DM, enrolled in the National Diabetes Care Management Program, and free of DPN (n =(More)
