Comprehensive Cardiometabolic Health Assessment

Check if the same lab product or an alternative is used in the 5 most similar protocols
We examined blood pressure, BMI, and waist circumference at the navel level during minimal respiration. All participants completed a self-administered questionnaire that documented medical history, medication, smoking habit, alcohol consumption habit, the frequency and intensity of daily exercise, eating habits, and sleeping habit. Types of medication for hypertension and dyslipidemia were unknown in 13 and 12 subjects, respectively. Average ethanol consumption per day was approximately calculated as follows: (the frequency of alcohol consumption) × (the amount of alcohol consumed once). Serum markers including triglyceride (TG), high density lipoprotein cholesterol (HDL-C), low density lipoprotein cholesterol (LDL-C), lipoprotein a (Lp(a)), apolipoprotein A1 (ApoA1), apolipoprotein B (ApoB), glucose, hemoglobin A1c (HbA1c), homeostasis model assessment of insulin resistance (HOMA-R), uric acid (UA), and highly sensitive C reactive protein (hs-CRP) were measured. Blood samples were collected after fasting overnight and immediately analyzed using an automated clinical chemical analyzer. We examined urinary protein and blood excretion in urine samples using dipstick testing. VFA was measured at the navel level using a single-slice CT scan (Aquilion CXL; Toshiba Medical Systems Corporation, Tochigi, Japan).

Cardiometabolic Risk Factors Assessment

We obtained information on age, sex, body mass index (BMI, kg/m2), waist circumference at the level of the navel during minimal respiration, cigarette smoking status, alcohol consumption, medication, and sleeping hours from the questionnaires. In terms of alcohol consumption, frequency of alcohol drinking (number of days per week) and quantity consumed on days during which drinking occurred (gram ethanol per drinking day) were asked separately. The frequency and intensity of daily exercise, such as sweating for more than 30 minutes twice a week or walking for one hour or more in a day, and eating habits, such as skipping breakfast 3 times a week, having late evening snack 3 times a week, and having late dinner 3 times a week, were also asked using questionnaires. Blood pressure and blood markers including triglyceride (TG), high-density lipoprotein cholesterol (HDL-C), low-density lipoprotein cholesterol (LDL-C), hemoglobin A1c (Hb-A1c), homeostatic model assessment of insulin resistance (HOMA-R), and uric acid (UA) were measured. In addition, visceral fat area (VFA) was measured at the navel level using a single-slice CT scan (Aquilion CXL; Toshiba Medical Systems Corporation, Tochigi, Japan).

Multimodal Imaging Techniques for Comprehensive Evaluation

Check if the same lab product or an alternative is used in the 5 most similar protocols
CEUS: The ultrasound equipment was as follows: Convex transducers and a Contrast Harmonic Imaging mode were used. A 2.4-mL bolus of SonoVue (Bracco Imaging SpA, Milan, Italy) was injected into the antecubital vein and then received a flush with 5 mL of 0.9% saline solution. The examination needs to be continued for up to 6 min.
CECT: CECT was performed with one of the following equipment: a 64-detector row (Aquilion CXL, Toshiba Medical System, Tokyo, Japan) or 320-detector row CT machine (Aquilion One, Toshiba Medical System, Tokyo, Japan). 1.5 mL/kg of contrast media (Ultravist, Bayer, Germany) was injected into an antecubital vein at a rate of 3.0 mL/s via a pump injector (P3T abdomen module, Medrad Inc.).
CEMRI: MRI examination was performed by using a 3.0-T system (Siemens Healthineers). Gd-EOB-DTPA (Primovist®, 0.1 mL/kg body weight) with a flow rate of 1 mL/s was injected into an antecubital vein.
Imaging protocols and scanning parameters of CEUS, CECT, and CEMRI examination are described in Supplementary Material S1.

Respiratory specimens were collected, and the severe acute respiratory distress syndrome CoV-2 virus nucleic acid test was detected by using real-time RT-PCR (Liferiver Bio-Tech, Shanghai, China). CT was performed using a 64-slice scanner (Aquilion CXL, Toshiba Medical, Japan). The CT score was accessed by using the total lung severity score with a 5-point scale, as described by previously.[26 (link)] Symptom score was calculated as described previously.[27 ]

Evaluating Vertebral Failure via CT Scans

Check if the same lab product or an alternative is used in the 5 most similar protocols
To determine whether a vertebral failure had occurred, CT scans of fully fixated specimens in their final loading position were generated and compared to the specimens' pre-experimental CT scans. To both facilitate fracture detection and to capture the specimens' post-failure state, the specimens were fixated by embedding them in PMMA that was contained by a plastic bag, while the specimens were in the final loading position ( Fig. 3 ). Post-experiment CT images (Aquilion/CXL, Toshiba Medical, Otawara, Japan) were acquired (resolution 0.6 × 0.6 × 0.6 mm). Preand post-experiment CT scans were evaluated by an experienced radiologist to determine the occurrence of a fracture and/or collapse in one of the vertebral bodies. Experiments in which only the middle vertebra had failed were defined as successful. In contrast, experiments in which the upper or lower vertebrae failed, either or not in combination with the middle vertebrae, were defined as unsuccessful. For the successful experiments, we determined the experimental load to failure from the force-displacement curves.

CECT was performed at our institute with one of the following machines: a 64-detector row (Aquilion CXL, Toshiba Medical System, Tokyo, Japan) or 320-detector row CT machine (Aquilion One, Toshiba Medical System, Tokyo, Japan). We used the same scanning parameters for both machines as follows: tube voltage, 120 kV; tube current, 250 mA; and slice thickness, 1 mm. After a routine unenhanced scan, 1.5 mL/kg of contrast media (Ultravist, Bayer, Germany) was injected into an antecubital vein at a rate of 3.0 mL/s via a pump injector (P3T abdomen module, Medrad Inc.). Hepatic arterial phase CT images were obtained at 35 s, and portal venous phase CT images were obtained at 65 s [23 (link), 24 (link)].

About PubCompare

Our mission is to provide scientists with the largest repository of trustworthy protocols and intelligent analytical tools, thereby offering them extensive information to design robust protocols aimed at minimizing the risk of failures.

We believe that the most crucial aspect is to grant scientists access to a wide range of reliable sources and new useful tools that surpass human capabilities.

However, we trust in allowing scientists to determine how to construct their own protocols based on this information, as they are the experts in their field.
