Patients were attached to either an INVOS (Somenetics, Inc., Troy, MI) or Foresight (CAS Medical Systems, Branford, CT) NIRS monitor, depending on availability. Electrodes for monitoring NIRS were placed on the right and left forehead using the respective manufacturer’s recommendations and after first cleaning the skin with an alcohol swab. Transcranial Doppler monitoring (Doppler Box, DWL, Compumedics, USA, Charlotte, NC) of the middle cerebral arteries was with two 2.5-MHz transducers fitted on a headband. The depth of insonation varied between 35 and 52 mm until representative spectral artery flow was identified.
Analog arterial pressure data from the operating room hemodynamic monitor, TCD, and NIRS signals were sampled with an analog-to-digital converter at 60 Hz and then processed with ICM+ software version 6.1 (University of Cambridge, Cambridge, UK). These signals were time-integrated as non-overlapping 10-second mean values, which is equivalent to applying a moving average filter with a 10-second time window and re-sampling at 0.1 Hz. This operation was used to eliminate high-frequency noise from the respiratory and pulse frequencies, while allowing detection of oscillations and transients that occur below 0.05 Hz. Doppler, oximetry, and arterial blood pressure waveforms were further high pass filtered with a DC cutoff set at 0.003 Hz. This step removed slow drifts associated with hemodilution at the onset of bypass, blood transfusions, cooling, and rewarming. A continuous, moving Pearson’s correlation coefficient was calculated between the MAP and TCD blood flow velocities and between MAP and NIRS data, rendering the variables Mx (mean velocity index) and COx (cerebral oximetry index), respectively. Of note, MAP is used in this calculation and not cerebral perfusion pressure since intracranial pressure data are not available and since central venous pressure is often negative as a result of suction assisted venous drainage to the CPB reservoir. Consecutive, paired, 10-second averaged values from 300 seconds duration were used for each calculation, incorporating 30 data points for each index. Intact CBF autoregulation is indicated by an Mx value of approximately zero (CBF and MAP are not correlated), and CBF dysautoregulation is indicated by an Mx value approaching +1 (CBF and MAP correlated). Similar findings occur experimentally with COx.13 (link)

Clamps were performed according to recent recommendations of the Mouse Metabolic Phenotyping Center Consortium (15 (link)). After surgical implantation of an indwelling catheter in the right jugular vein, the mice were allowed to recover for 1 week prior to clamp experiments. Following an overnight 14-h fast, the mice were infused with 3-[3H]glucose at a rate of 0.05 μCi/min for 120 min to determine basal glucose turnover. Next, a primed infusion of insulin and 3-[3H]glucose was administered at 7.14 milliunits·kg−1·min−1 and 0.24 μCi/min, respectively, for 4 min, after which the rates were reduced to 3 milliunits·kg−1·min−1 insulin and 0.1 μCi/min 3-[3H]glucose for the remainder of the experiment. Blood was collected via tail massage for plasma glucose, insulin, and tracer levels at set time points during the 140-min infusion, and a variable infusion of 20% dextrose was given to maintain euglycemia. Glucose turnover was calculated as the ratio of the 3-[3H]glucose infusion rate to the specific activity of plasma glucose at the end of the basal infusion and during the last 40 min of the hyperinsulinemic-euglycemic clamp study. Hepatic glucose production represents the difference between the glucose infusion rate and the rate of glucose appearance. A 10-μCi bolus injection of [14C]2-deoxyglucose was given at 90 min to determine tissue-specific glucose uptake, which was calculated from the area under the curve of [14C]2-deoxyglucose detected in plasma and the tissue content of [14C]2-deoxyglucose-6-phosphate, as previously described (16 (link)). Following collection of the final blood sample, the mice were anesthetized with an intravenous injection of 150 mg/kg pentobarbital, and tissues were harvested and froze with aluminum forceps in liquid nitrogen. All of the tissues were stored at −80 °C until later use.

Timed urine samples were obtained from hospitalized patients with indwelling Foley catheters. Individuals provided written informed consent, and the protocol was approved by the BWH (Brigham and Women’s Hospital) Institutional Review Board. For each collection, the Foley catheter and tubing was emptied of urine before the timed collection. At the end of the timed collection, the entire volume of urine in the Foley catheter and tubing was drained. The volume of collected urine was noted and an aliquot from the entire volume was obtained for biomarker analyses. Urine samples were centrifuged at 3200 r.p.m. and the supernatant was stored at −80°C in 1.8 ml Eppendorf tubes. Within 3 months of collection, urine samples were thawed, vortexed, and centrifuged at 14,000 r.p.m. at 4°C and 30–100 μl of the supernatant was pipetted for biomarker measurements. UCr was measured in the BWH clinical laboratory by the Jaffe assay using the Roche/Hitachi Cobas C system (Roche Diagnostics, Indianapolis, IN, USA). Urinary KIM-1 concentration was measured using a microbead assay as described previously.38 (link) For each timed collection, we calculated the extrapolated 24 h excretion rate of creatinine and KIM-1 (concentration × volume × 24 h/time of collection), as well as the creatinine-normalized KIM-1 concentration (KIM-1 concentration/urine creatinine concentration). AKI was defined as a ≥ 50% increase in SCr over baseline or admission values. DGF was defined as a < 10% decrease in SCr per day for the first 3 days after transplantation. PGF was defined as a > 50% decrease in SCr within 3 days after transplantation. SGF was defined as a < 50% decrease in SCr within 3 days after transplantation, excluding those who met the criteria for DGF.

Longitudinal plasma samples were prospectively collected from 251 critically-injured trauma patients at a single Level 1 Trauma Center on arrival and at 2, 3, 4, 6, 12, 24, 48, 72, 96, and 120 hours after admission to a Level I urban trauma intensive care unit (ICU).
Our methodology for collection of whole blood for viscoelastic testing has been described previously (17 (link)). Briefly, admission samples were collected via initial placement of a 16G or larger peripheral intravenous line; subsequent samples were collected via indwelling arterial catheters. Standard laboratory vacuum-sealed tubes containing 3.2% (0.109 mol/L) sodium citrate were used for all draws. After a waiver of consent was applied for initial blood draws, informed consent was obtained from all patients, as approved by the University of California Committee on Human Research. A total of 603 samples were analyzed on 251 patients. Demographics, resuscitation data, clinical laboratory results, and outcomes were collected in parallel. Point-of-care thromboelastography (TEG) was performed to assess viscoelastic properties of clot formation with the TEG 5000 (Haemonetics; Niles, Il) immediately after sample collection. One mL of citrated whole blood was added to a manufacturer-standardized vial containing the clotting activator kaolin and mixed. Following this, 340 uL was transferred from the kaolin vial to the TEG cup, warmed to 37°C, and recalcified with 20 uL of 0.2 mol/L CaCl2. For the FF TEG, 500 uL of citrated blood was added to the FF vial (kaolin + glycoprotein IIb/IIIa antagonist) and mixed; 340 uL was then transferred to the TEG cup, and warmed and recalcified as above. In parallel, plasma fibrinogen concentration was assayed by the von Clauss method (11 (link)) and plasma-based standard coagulation measures were performed. Platelet contribution to clot strength was calculated as MATEG−MAFF=MAplatelets. Percentage contributions of FF (%MAFF) and platelets (%MAplatelets) were calculated as each respective MA divided by the overall kaolin TEG MA. Coagulopathy was defined by admission INR>=1.3. Thrombocytopenia was defined by platelets <= 200. Multi-organ failure was defined using the Denver Postinjury Multiple Organ Failure Score (18 (link)–20 (link)).
Data are presented as mean (SD), median (interquartile range), or percentage; univariate comparisons were made using Student’s t test for normally distributed data, Wilcoxon rank sum or Kruskal Wallis testing for skewed data, and Fisher’s exact test for proportions. Intergroup comparisons between multiple groups were only judged significant when corrected for multiple comparisons using a standard Bonferroni correction. Linear regression was used to assess correlations between prospectively collected TEG values and laboratory values. Cox proportional hazards regression was used to identify predictors of mortality. An [alpha] = 0.05 was considered significant. All analysis was performed by the authors using Stata version 12 (StataCorp, College Station, TX).

Following acclimation to the animal facility, rats were implanted with chronic indwelling intravenous catheters while under ketamine/xylazine anesthesia (+ equithesin in some cases). A non-steroidal anti-inflammatory was administered as an analgesic prior to surgery. The catheters were constructed of silastic tubing (Dow Corning, Midland, MI) connected to a modified guide cannula (C313G-5UP-SPC12, Plastics One, Roanoke, VA), which was mounted on ProLite polypropylene monofilament mesh (Atrium, Hudson, NH) using Ortho-Jet acrylic (Lang Dental, Wheeling, IL); a small silicone bubble was placed 3.8 cm from the end of the silastic tubing. Briefly, the free end of silastic tubing was inserted into (and secured to) the right jugular vein, while the other end passed subcutaneously over the shoulder to the cannula which was mounted on the back and exited via a biopsy hole. Beginning 3 days after surgery, catheters were flushed once daily with 0.1 ml each of the antibiotic cefazolin (100 mg/ml) and heparin (100 U/ml). For each self-administration session, catheters were flushed with 0.1 ml saline to ensure patency prior to attachment to the cocaine infusion line (PE-50 tubing) and spring tether in the self-administration chamber, and flushed with 0.1 ml each of cefazolin and heparin following the session. Self-administration sessions began after one week of recovery from surgery.

COPRA is the standard PDMS documentation programme for all anaesthesiology and ICU units at the Charité Universitätsmedizin Berlin. Since 2015, premedication rounds, surgical protocols, postoperative recovery room stays and all aspects of treatment at the intensive care units, as well as in the pain clinic, have been fully and transparently documented in this program (COPRACOPRA6).
The COPRA6 program allows data exchange with the POD documentation form, so that scores (validated delirium screening scores, pain scores, anxiety score) are directly transferred into the POD documentation form and are available for all medical staff. In the surgical setting, and postoperatively in the recovery room or intensive care unit, all non-pharmacological preventive measures are already part of the standard procedure and are mapped and documented in the protocols of these areas (operation/intensive care unit/ recovery room). The COPRA6 form for the documentation of preventive measures during the postoperative phase on the normal ward is divided into five domains: (1) delirium screening, (2) pain/stress/anxiety screening, (3) stimulation of cognition and circadian rhythm, (4) nutrition and mobilisation and (5) indwelling catheters and external devices (online supplemental table S4). The domains can be accessed easily and independently using a sidebar. Each domain contains queries on non-pharmacological preventive measures, which are stored along with the date and time of the conducted visit. The checklist format is kept for the postoperative phase and is intended to ensure that staff can complete it quickly and easily during bedside visits. When patients are discharged or transferred from the hospital, the documentation in the postoperative COPRA6 application also ends with a final query on the presence of delirium. Patients affected by a POD will be offered a follow-up consultation to the out-patient anaesthesiology department 3 months after discharge.

Patient demographics and clinical characteristics at enrollment were collected from patient medical records. The effectiveness of the EUDFA was operationally defined as the percentage of urine diverted by the system in relation to the volume of urine collected in the incontinence pads and liners. The total volume of urine represented the volume of urine remaining in the EUDFA, standard incontinence pads, soft incontinence liners, and the volume of urine collected in the canister. Dry weights of each were subtracted from wet weights (in grams, which equals milliliters) to determine the portion of urine output diverted by the device. Data regarding indwelling catheter usage, CAUTIs, UI, and IAD were obtained from documentation related to hospital quality monitoring criteria. The CAUTI rate was calculated as the number of CAUTIs per 1000 indwelling catheter-days during the year. Indwelling catheter use was calculated as the total number of indwelling catheter-days divided by the total number of patient-days during the year and presented as a percentage. Incontinence was defined as UI and/or fecal incontinence (FI) identified on visual inspection during the monthly pressure injury prevalence survey. Incontinence-associated dermatitis was defined as skin irritation present (yes/no) in the area of incontinence. The percentage with IAD was calculated among those with UI and/or FI.

60 people received one cc of normal saline (1 ml) as a placebo two minutes before changing from lithotomy to supine position.
Each ephedrine syringe contained 50 mg of ephedrine diluted with 9 ml of distilled water in 10 cc syringes, each cc containing 5 mg of ephedrine. The placebo syringes were in the form of 10 cc syringes containing distilled water, and two minutes before changing the lithotomy position to the supine position, one cc of each was randomly injected intravenously into the patients in the study groups. The patients, surgeons, and anesthesiologists were blinded to the allocation of the patients to the studied groups. All aseptic precautions were conducted before performing the spinal anesthesia. Spinal anesthesia was performed with a #25 needle (SPINAL ANESTHESIA NEEDLE, Dr.J brand, made in Japan, Quincke type) in the sitting position from the third and fourth intervertebral space (midline approach) and by injecting 12.5 mg hyperbaric bupivacaine in the subarachnoid space. Then, the patients were placed in the supine position and received 4 liters of oxygen per minute during the operation through a simple face oxygen mask. Sensory levels were determined by the pinprick test after block (every 15–20 seconds for 3 minutes), and the motor blockade was evaluated using Bromage's criteria until the level of spinal anesthesia was raised to the T8 level.
Cystoscopy was performed in lithotomy position, a ureteric catheter was entered into the upper ureter or renal pelvis and fixed with tape to the indwelling Foley catheter, and patients were placed in the supine position. The patient's supine position changed to the prone position, and renal access was conducted in the prone position under fluoroscopic guidance; superior and inferior bolsters were placed at the xiphoid process cartilage to support the lower rib cage, and at the symphysis pubis, vertical bolsters were put in the standard manner along the lateral sides of the chest.
All vital parameters, including HR and NIBP, were recorded perioperatively the time before spinal anesthesia performing (T0), immediately after spinal anesthesia induction (T1), after the lithotomy position (T2), when lithotomy position changed to the supine position (T3), and then when the patient was placed in the prone position (T4). Afterward, vital signs were documented every 3 minutes for 60 minutes (T5–T25) and finally at the end of surgery time (Tf).
If the systolic blood pressure was under 100 mmHg or less than 20% from the baseline, it was treated with 5 mg ephedrine and increased crystalloid speed. If the heart rate (HR) was under 50 beats/minute, it was treated with 0.75 mg of atropine. The incidence of hypotension, bradycardia, nausea, vomiting, shivering, and other complications were recorded.

Twenty-four SD rats were fasted for 12 h (free access to water) and randomly classified into three groups (n = 8; half male and female) that received different doses of SZ-A solution (25, 50, and 200 mg/kg) via oral administration. After completion of dose administration, blood samples (0.3 mL) were collected through an indwelling catheter from the jugular vein at predetermined time points (5, 15, 30, and 45 min, 1, 2, 4, 8, and 24 h). The blood was centrifuged at 5,000 rpm for 10 min to separate the plasma. All plasma samples were stored frozen at −80°C until liquid chromatography coupled to tandem mass spectrometry (LC-MS/MS) analysis (AB SCIEX Triple Quad™ 4,500 mass spectrometer, Applied Biosystems Inc., United States).
