Swallowing kinematic analysis might be helpful in predicting aspiration and pyriform sinus stasis.

Aspiration due to dysphagia can lead to aspiration, which negatively impacts a patient's overall prognosis. Clinically, videofluoroscopic swallow study (VFSS) is considered the gold-standard instrument to determine physiological impairments of swallowing. According to previously published literature, kinematic analyses of VFSS might provide further information regarding aspiration detection.

The standardizing texture of thickened barium stimuli in the videofluoroscopic swallowing study at a medical center in Taiwan.

This study aimed to establish more practical standardized barium stimuli formulas for the videofluoroscopic swallowing study (VFSS) for clinical use. For clinical practice, we established the formula for preparing barium stimuli to comply with different International Dysphagia Diet Standardization Initiative (IDDSI) levels. To comply with the definition of IDDSI levels 0-4, the gum-based thickener concentration of thickened barium was 0, 0.

Allometric scaling and growth: Evaluation and applications in subadult body mass estimation.

Objectives: Previously developed methods in subadult body mass estimation have not been tested in populations other than European-American or African-American. This study uses a contemporary Taiwanese sample to test these methods. Through evaluating their accuracy and bias, we addressed whether the allometric relationships between body mass and skeletal traits commonly used in subadult body mass estimation are conserved among different populations.

Double bonds of unsaturated fatty acids differentially regulate mitochondrial cardiolipin remodeling.

Background: Supplemented fatty acids can incorporate into cardiolipin (CL) and affect its remodeling. The change in CL species may alter the mitochondrial membrane composition, potentially disturbing the mitochondrial structure and function during inflammation.

Method: To investigate the effect of the unsaturation of fatty acids on CL, we supplemented macrophage-like RAW264.

Predicting tumor responses and patient survival in chemoradiotherapy-treated patients with non-small-cell lung cancer using dynamic contrast-enhanced integrated magnetic resonance-positron-emission tomography.

Purpose: We investigated whether radiologic parameters by dynamic contrast-enhanced (DCE) integrated magnetic resonance-positron-emission tomography (MR-PET) predicts tumor response to treatment and survival in non-metastatic non-small-cell lung cancer (NSCLC) patients receiving chemoradiotherapy (CRT).

Methods: Patients underwent DCE integrated MR-PET imaging 1 week before CRT. The following parameters were analyzed: primary tumor size, gross tumor volume, maximal standardized uptake value (SUV), total lesion glycolysis (TLG), apparent diffusion coefficient (ADC), volume transfer constant (K), reverse reflux rate constant (k), extracellular extravascular volume fraction (v), blood plasma volume fraction (v), and initial area under the time-concentration curve defined over the first 60 s post-enhancement (iAUC).

Preoperative computed tomography-guided dye injection to localize multiple lung nodules for video-assisted thoracoscopic surgery.

Background: Preoperative computed tomography (CT)-guided localization of small lung nodules is important for accurate and efficient video-assisted thoracoscopic surgery (VATS). Resection of multiple small pulmonary nodules in one VATS procedure can aid in patient management. The aim of this study was to evaluate the usefulness of CT-guided Patent Blue V (PBV) dye localization in patients with multiple pulmonary nodules who underwent VATS.

Computed tomography-guided patent blue vital dye localization of pulmonary nodules in uniportal thoracoscopy.

Objective: Due to the limitations of the small single incision, an ideal preoperative localization technique is essential for surgical resection of small pulmonary nodules by uniportal video-assisted thoracoscopic surgery (VATS). The aim of this study is to evaluate the usefulness and safety of preoperative computed tomography (CT)-guided patent blue vital (PBV) dye localization in patients with small indeterminate pulmonary nodules who have undergone uniportal VATS for lung resection.

Methods: In this retrospective study, 177 consecutive patients (196 pulmonary nodules) who underwent preoperative CT-guided PBV dye localization and uniportal VATS from January 2013 to September 2015 were enrolled.

Novel sesquiterpene lactone analogues as potent anti-breast cancer agents.

Triple-negative breast cancer (TNBC) is associated with high grade, metastatic phenotype, younger patient age, and poor prognosis. The discovery of an effective anti-TNBC agent has been a challenge in oncology. In this study, fifty-eight ester derivatives (DETDs) with a novel sesquiterpene dilactone skeleton were organically synthesized from a bioactive natural product deoxyelephantopin (DET).

Evaluation of the treatment response to neoadjuvant chemotherapy in locally advanced breast cancer using combined magnetic resonance vascular maps and apparent diffusion coefficient.

Purpose: To evaluate the treatment response of locally advanced breast cancer (LABC) to neoadjuvant chemotherapy using magnetic resonance (MR) vascular maps and apparent diffusion coefficient (ADC) at 3T. Materials and Methods Thirty-one patients with LABC who underwent breast MR studies before, after the first course, and after completing neoadjuvant chemotherapy were enrolled. Vascular morphology was retrieved via Hessian matrix and the voxels of the vessels and volume of vessels were measured automatically.

Quantitative computed tomography of pulmonary emphysema and ventricular function in chronic obstructive pulmonary disease patients with pulmonary hypertension.

Objective: This study strived to evaluate the relationship between degree of pulmonary emphysema and cardiac ventricular function in chronic obstructive pulmonary disease (COPD) patients with pulmonary hypertension (PH) using electrocardiographic-gated multidetector computed tomography (CT).

Materials And Methods: Lung transplantation candidates with the diagnosis of COPD and PH were chosen for the study population, and a total of 15 patients were included. The extent of emphysema is defined as the percentage of voxels below -910 Hounsfield units in the lung windows in whole lung CT without intravenous contrast.

Do we need to wait longer for cardiac arrest survivor to wake up in hypothermia era?

Before the era of therapeutic hypothermia, a practice parameter including absent or extensor motor response at day 3 and the presence of myoclonus status epilepticus within 24 hours was used to assist prognostication of poor neurologic outcomes. There are conflicting results concerning whether hypothermia influences the reliability of the predictors and the accurate predictors and optimal timing for assessing neurologic recovery are largely unknown. Several prognostic indicators other than guidelines are also applied to help determining prognosis, including electroencephalogram, cerebral computed tomographic scan, and cerebral perfusion scintigraphy single-photon emission computed tomographic scan.
