Standardized long-term follow-up after endoscopic resection of large, nonpedunculated colorectal lesions: a prospective two-center study.
2014
Endoscopic removal of large, nonpedunculated colorectal lesions is challenging. Long-term outcome data based on standardized protocols, including detailed inspection of the resection site, are scarce. The aims of the present study were to evaluate the safety and efficacy of endoscopic resection (ER) of large, nonpedunculated lesions (LNLs;20 mm) and to assess the long-term recurrence rate afterward.A total of 243 consecutive patients (141 men, 102 women) with 252 adenomas (20 mm) was followed up using a standardized protocol after complete ER. After endoscopic treatment, the patients received standardized follow-up examinations after 3-6 months and 12 months. The postpolypectomy scar was re…
Interpretation of intraoperative parathyroid hormone monitoring according to the Rome criterion in primary hyperparathyroidism
2022
AbstractIntraoperative parathyroid hormone dosage allows real-time monitoring of the decrease in PTH levels during parathyroidectomy and verify procedure’s efficacy. Currently, none of the interpretative criteria used has absolute accuracy. The aim of this study is to evaluate diagnostic accuracy of the Rome criterion verifying diagnostic significance of the individual assays. A total of 205 patients with primary hyperparathyroidism from a single adenoma were retrospectively evaluated and monitored with baseline PTH, PTH at 10 min and PTH at 20 min after adenoma excision. The accuracy of the latter two assays compared with baseline was compared by ROC curves. In addition, was evaluated the …
Covert digital manipulation of vocal emotion alter speakers' emotional states in a congruent direction
2016
International audience; Research has shown that people often exert control over their emotions. By modulating expressions, reappraising feelings, and redirecting attention, they can regulate their emotional experience. These findings have contributed to a blurring of the traditional boundaries between cognitive and emotional processes, and it has been suggested that emotional signals are produced in a goal-directed way and monitored for errors like other intentional actions. However, this interesting possibility has never been experimentally tested. To this end, we created a digital audio platform to covertly modify the emotional tone of participants' voices while they talked in the directi…
Anaesthetic techniques to prevent perioperative stroke.
2013
Different techniques and interventions that can be used by an anaesthesiologist to minimize the perioperative stroke risk are summarized.The most important risk factors for perioperative stoke are not modifiable, for example previous stroke or renal failure, but they can be used to identify patients with a high risk for perioperative stroke. The antiplatelet therapy should be continued in patients with a high risk for cardiovascular thrombosis. This might be true even for operations in which bleeding should be strictly avoided such as eye surgery. One of the most recent neuroprotective approaches is the remote ischaemic preconditioning.Perioperative stroke increases morbidity and mortality …
Brain tissue pO2 related to SjvO2, ICP, and CPP in severe brain injury
2000
The aim of this report is to present first experience in comparing the course of brain tissue oxygen pressure values (PtiO2) to changes in jugular vein oxygen saturation (SjvO2), intracranial pressure (ICP), and cerebral perfusion pressure (CPP) after severe brain injury. PtiO2 monitoring was done using a polarographic Clark type microcatheter (LICOX pO2 probe) (GMS, Kiel, Germany) with a diameter of 0.5 mm and a sensitive area 7.9 mm long inserted in a right frontal position. The microcatheter was connected to a LICOX pO2 device. A fiber-optic catheter was used to measure SjvO2 and placed into the right internal jugular vein. The ICP monitoring was performed with a fiber-optic intraparench…
Multi-occurrence of twenty mycotoxinsin pasta and a risk assessment in the moroccan population
2018
In the present study, the multi-occurrence of twenty (20) mycotoxins in pasta samples consumed in Morocco was assessed. For this, a modified Quick, Easy, Cheap Effective, Rugged, and Safe method was validated. The mycotoxins studied were identified and quantified by liquid chromatography&ndash
Determination of four parabens and bisphenols A, F and S in human breast milk using QuEChERS and liquid chromatography coupled to mass spectrometry
2018
Abstract For the first time, a multiresidue, sensitive and high throughput method for determination of bisphenol A, F and S and 4 parabens (methyl paraben, ethyl paraben, propyl paraben and butyl paraben) in human breast milk was developed. The proposed method includes an extraction and clean-up procedure based on QuEChERS methodology followed by liquid chromatography coupled to triple quadrupole mass spectrometry determination. Negative atmospheric pressure chemical ionization in the selected reaction monitoring mode was used for mass detection. During the method validation the recoveries varied between 83 and 115% with a precision lower than 20% for all analytes using spiked levels from 0…
Impact of physical exercise on sensor performance of the FreeStyle Libre intermittently viewed continuous glucose monitoring system in people with Ty…
2019
AIMS To evaluate the sensor performance of the FreeStyle Libre intermittently viewed continuous glucose monitoring system using reference blood glucose levels during moderate-intensity exercise while on either full or reduced basal insulin dose in people with Type 1 diabetes. METHODS Ten participants with Type 1 diabetes [four women, mean ± sd age 31.4 ± 9.0 years, BMI 25.5±3.8 kg/m2 , HbA1c 55±7 mmol/mol (7.2±0.6%)] exercised on a cycle ergometer for 55 min at a moderate intensity for 5 consecutive days at the clinical research facility, while receiving either their usual or a 75% basal insulin dose. After a 4-week washout period, participants performed the second exercise period having sw…
How often patients on insulin therapy measure postprandial glycemia and modify insulin doses accordingly? From an on-line survey in insulin-treated d…
2019
Abstract Introduction Controlling postprandial glycemia (PPG) is important to achieve optimal glycemic control, but few studies have evaluated how often is measured and evaluated. Objectives To evaluate how often patients on insulin therapy measure PPG and modify insulin doses accordantly. As secondary objectives, we evaluated the factors conditioning elevated PPG and associated issues. Material and methods Cross-sectional observational study based on a web-based survey from an unselected sample of adult insulin-treated patients. A p-value of Results 1251 patients (68% women, 38.9 ± 13 years [mean ± SD], body mass index (BMI) 24.2 ± 4.2 kg/m2, diabetes duration 17.4 ± 12.8 years, insulin d…
Evaluation of CGMS® During Rapid Blood Glucose Changes in Patients with Type 1 Diabetes
2006
CGMS (Medtronic Minimed, Duesseldorf, Germany) allows continuous glucose monitoring. Recent studies with invasive monitoring techniques revealed discrepancies in blood glucose measurements obtained from different anatomical sites compared with those from the fingertip. The aim of this study was to investigate the CGMS and a device for alternative site testing (AST) during dynamic blood glucose changes and to compare these results with fingertip measurements.Twelve patients with type 1 diabetes (seven women, five men; age, 33.3 +/- 8.7 years) received a 75-g oral glucose load. Insulin was applied intravenously (rapid glucose decline) or subcutaneously (moderate glucose decline) in a dosage b…
