This paper introduces the 'Spatially Focused Saline-based Pressure Sensor (SF-SaPS)', a novel soft microfluidic pressure sensor featuring a distinctive three-dimensional focusing structure. By critically reducing the cross-sectional area of the microchannel at the focused structure, the SF-SaPS achieves excellent sensitivity to pressure within the sensing region. With the spatially focused region, the SF-SaPS could detect a wide range of pressure from gentle touches to human weight, which is typically unachievable with low-conductivity sensing media such as saline, a medium inherently safe for human use.

Article Synopsis
- Early recognition of sepsis and timely treatment are essential for better patient outcomes, with quality improvement programs showing positive effects in sepsis care.
- A multidisciplinary sepsis task force implemented a program over 24 months, focusing on screening and monitoring through a sepsis flowsheet in the emergency department.
- Key improvements included a rise in timely antibiotic administration from 44% to 84%, significant enhancements in fluid and lab test administration, and a reduction in mortality rates from 32% to 21%.

Sevelamer, a nonabsorbable dietary phosphate binder, is essential for patients with renal impairment since hyperphosphatemia is associated with an increase in all-cause mortality. Sevelamer is generally well tolerated; however, it is rarely been documented to cause gastrointestinal mucosal injury by forming sevelamer crystals and depositing within the gastrointestinal walls. We present a 35-year-old man with end-stage renal disease on peritoneal dialysis who developed abdominal pain and hematochezia.

However, the method's potential influence on the material's mechanical properties is often overlooked during single-point experimentation. Saline and formaldehyde solutions are the most common among the employed preservation media.
