Sensors, Vol. 19, Pages 4039: Commercial Screen-Printed Electrodes Based on Carbon Nanomaterials for a Fast and Cost-Effective Voltammetric Determination of Paracetamol, Ibuprofen and Caffeine in Water Samples Sensors doi: 10.3390/s19184039 Authors: Núria Serrano Òscar Castilla Cristina Ariño M. Diaz-Cruz José Díaz-Cruz Carbon screen-printed electrode (SPCE), multi-walled carbon nanotubes modified screen-printed electrode (SPCNTE), carbon nanofibers modified screen-printed electrode (SPCNFE), and graphene modified screen-printed electrode (SPGPHE) were in a pioneer way tested as sensors for the simultaneous determination of the two most consumed pain-killers, paracetamol (PA) and ibuprofen (IB), and the stimulant caffeine (CF) in water by differential pulse voltammetry (DPV). Their analytical performances were compared, and the resulting sensitivities (2.50, 0.074, and 0.24 μA V mg−1 L for PA, IB, and CF, respectively), detection limits (0.03, 0.6, and 0.05 mg L−1 for PA, IB, and CF, respectively) and quantification limits (0.09, 2.2, and 0.2 mg L−1 for PA, IB, and CF, respectively) suggested that the SPCNFE was the most suitable carbon-based electrode for the voltammetric determination of the selected analytes in water at trace levels. The methodology was validated using both spiked tap water and hospital wastewater samples. The results were compared to those achieved by liquid chromatography–tande...
ConclusionsPhysical and psychological functioning, pain, fatigue and appetite loss had prognostic significance above and beyond clinical predictors in CRC. Routine monitoring of these PROs may allow earlier detection and amelioration of problems, which may improve quality of life and perhaps extend survival. More research is needed to determine prognostic value of PROs in early-stage CRC, and prognostic significance of changes in PRO scores.
Research has shown that the experience of Childhood Sexual Abuse (CSA) can increase the rates of physical and emotional sequela, including depression, anxiety, PTSD, and physical pain. However, little is known about the healing journeys for those women who...
Patients with critical limb ischemia are exposed to qualitative and quantitative malnutrition as a result of anorexia caused by chronic pain, insomnia, overuse of analgesics, and limitation of mobility. Furthermore, malnutrition is a well-known factor that causes coagulation disorders and immunosuppression, and it directly adversely affects the wound healing process. The aim of this study was to assess the influence of qualitative and quantitative malnutrition on the results of revascularization procedures as frequency of large amputations in patients with critical lower limb ischemia.
True anterior tibial artery aneurysms attributed to nontraumatic causes are rare, and only a few cases have been published since 1967. A 28-year-old man was referred to the emergency department with a history of swelling, pain, and footdrop of the left lower limb for the past 7 days. The patient did not report any history of trauma. Examination revealed compartment syndrome, and imaging studies showed an aneurysm of the left anterior tibial artery with dilated veins on the overlying skin as well as mild erythema (Figs 1 and 2).
Chronic low back pain (CLBP) is highly prevalent, associated with substantial socioeconomic impact, and commonly attributed to neurologic and musculoskeletal causes. We observed an unexpected prevalence of CLBP preoperatively among our patients with proximal venous outflow obstruction (PVOO) of the iliac veins undergoing stent placement. We undertook this study to better characterize these patients.
We describe our initial experience using TRA for endovascular intervention with SDD at a community hospital.
I’m in Italy for a vacation and went to Lurisia in Piemonte for a spa Terme . Was reading about it when I read about the hot springs had High amounts of Radon in the water. Learned that Marie Curie has visited in 1906 and was excited about the radiation. There are several places in Germany, Austria that also have high radon. I canceled my massage and was surprised this still is allowed. To my surprise discovered there are old mines in Montana that are high in radon where people go for pain... Radon spas and Montana mines
Hey peeps, Need some advice. Doing my pain fellowship. Having some occasional issues pushing meds into joints during procedures - particularly SI joints ugh. I have small hands, attending jokingly (or not so jokingly? ) asked me if I was using weights. Any suggestions? Becoming frustrating.
hello all. I had a new situation in clinic today which I previously didn’t encounter.Long story short. Patient with a known history of meth abuse Who admits to smoking the night before leaves work, is an unrestrained driver in a singe car accident. shows up in my office with severe right sided Neck pain. States that he continues to use meth with last use yesterday. He can’t turn his neck more than 10° rotation, and is actively using meth. Has anyone ever taking someone’s drivers license... Revoking a drivers license?
