OBJECTIVES Implementation of the International Statistical Classification of Disease and Related Health Problems, 10th Revision (ICD-10) coding system presents challenges for using administrative data. Recognizing this, we conducted a multistep process to develop ICD-10 coding algorithms to define Charlson and Elixhauser comorbidities in administrative data and assess the performance of the res...

PURPOSE The aim of this study was to evaluate the correlation between central lymph node (CLN) metastasis and clinicopathologic characteristics of papillary thyroid cancer (PTC). In addition, we investigated the incidence and risk factors for contralateral CLN metastasis in unilateral PTC. This study suggests the appropriate surgical extent for CLN dissection. METHODS A prospective study of 5...

The current 7th TNM staging stratifies N1b papillary thyroid cancer (PTC) patients without distant metastasis into either stage I or stage IV merely by an age threshold (45 years). To date, no studies have adequately quantified the mortality risk of PTC patients with N1b disease. We hypothesized that incorporating lymph node (LN) factors into the staging system would better predict cancer-speci...

BACKGROUND In order to avoid microaspiration and tracheal injury, the target for endotracheal tube cuff pressure is 20 to 30 cm H2O. OBJECTIVE To assess the effect of changes in body position on cuff pressure in adult patients. METHODS Twelve orally intubated and sedated patients received neuromuscular blockers and were positioned in a neutral starting position (backrest, head-of-bed elevat...

Sub-Doppler excitation spectroscopy in a collimated cold supersonic beam of 5% NO seeded in argon has been performed with a spectral resolution down to 10 MHz for four vibronic bands within the perturbed B ?X A system of NO . The rotational temperature of about 15 K achieved by adiabatic cooling allows the separation of closely lying vibronic bands which overlap in absorption spectra ...

The performance of bilirubin oxidase (BOx) based air breathing cathode was constantly monitored over 45 days. The effect of electrolyte composition on the cathode oxygen reduction reaction (ORR) output was investigated. Particularly, deactivation of the electrocatalytic activity of the enzyme in phosphate buffer saline (PBS) solution and in activated sludge (AS) was evaluated. The greatest drop...

Objective. The aim of this study was to identify the risk factors associated with central lymph node metastasis (CLNM) in patients with clinically node-negative conventional papillary thyroid carcinoma (cN0 CPTC). Methods. A total of 190 cN0 CPTC patients who underwent thyroidectomy with prophylactic central neck dissection (pCND) in the Department of General Surgery at Guangdong General Hospit...

Starting from the relativistic realistic nucleon-nucleon ($NN$) interactions, a newly developed \textit{ab initio} method, i.e., Brueckner-Hartree-Fock (RBHF) theory in full Dirac space is employed to study neutron star properties. First, one-to-one correspondence relation for gravitational redshift and mass established used infer of isolated stars combining measurements. Next, ratio moment ine...

BACKGROUND Lymph node metastasis in papillary thyroid carcinoma (PTC) is common; however, the need for prophylactic central lymph node dissection (CLND) in PTC is still controversial. The objective of this study was to investigate the risk factors of central lymph node metastasis (CLNM) in clinically lymph node-negative (cN0) PTC patients. MATERIAL AND METHODS A total of 529 cN0 PTC patients ...
