Evaluation of Dose Calculation Based on Cone-Beam CT Using Different Measuring Correction Methods for Head and Neck Cancer Patients.

To investigate and compare 2 cone-beam computed tomography (CBCT) correction methods for CBCT-based dose calculation. Routine CBCT image sets of 12 head and neck cancer patients who received volumetric modulated arc therapy (VMAT) treatment were retrospectively analyzed. The CBCT images obtained using an on-board imager (OBI) at the first treatment fraction were firstly deformable registered and padded with the kVCT images to provide enough anatomical information about the tissues for dose calculation.

Nomogram-Based Prediction of Overall and Disease-Specific Survival in Patients With Postoperative Major Salivary Gland Squamous Cell Carcinoma.

The major salivary gland squamous cell carcinoma is a rare head and neck tumor, often accompanied by lymph node metastasis. Even if the patient undergoes surgery, the prognosis remains unsatisfactory. To explore the prognostic factors of postoperative major salivary gland squamous cell carcinoma to establish a prognostic risk stratification model to guide clinical practice.

Effect of an IMB Model-Based Education on the Acceptability of HPV Vaccination Among College Girls in Mainland China: A Cluster RCT.

Objective: Despite the fact that the human papillomavirus vaccine (HPVV) has been approved in mainland China since 2016, there is a lack of inoculation among Chinese college women. This multi-center, online interventional RCT based on the information-motivation-behavioral skills (IMB) model intended to investigate if the intervention may improve human papillomavirus vaccine acceptance and awareness among target women.

Methods: Participants were selected from comprehensive universities and allocated to 1 of 2 groups: intervention or control.

Prevalence and Predictors of PTSD During the Initial Stage of COVID-19 Epidemic among Female College Students in China.

Background: College students are vulnerable and may experience high stress due to COVID-19, especially girls. This study aims to identify posttraumatic stress disorder (PTSD) and related factors among the target population during the initial phases of the COVID-19 pandemic.

Methods: In the initial phase of COVID-19 epidemic (February 23 to March 5, 2020), 2205 female college students from six provinces in mainland China were enrolled in this study and completed the online survey about the cognitive status of COVID-19, including the Impact of Event Scale-6, the Multidimensional Perceived Social Support Scale and a self-developed 10-item Perceived threat scale.

Willingness to Accept Human Papillomavirus Vaccination and its Influencing Factors Using Information-Motivation-Behavior Skills Model: A Cross-Sectional Study of Female College Freshmen in Mainland China.

Background: This study aimed to assess the awareness and attitudes toward human papillomavirus (HPV) vaccination among female college freshmen and explore their willingness and associated factors to receive the HPV vaccine based on the information-motivation-behavior skills (IMB) model.

Methods: From February 21 to April 30, 2020, a cross-sectional survey was conducted among female freshmen in seven colleges in mainland China. Socio-demographic characteristics, health-related awareness, knowledge of HPV, motivation, and behavioral skills toward HPV vaccination were assessed using questionnaires.

GCN2 Regulates ATF3-p38 MAPK Signaling Transduction in Pulmonary Veno-Occlusive Disease.

Pulmonary veno-occlusive disease (PVOD) is a fatal disease of pulmonary vascular lesions leading to right heart failure. Heritable PVOD (hPVOD) is related to biallelic mutation of (encoding GCN2), but its molecular mechanism remains unclear. In this study, we aimed to investigate the pathogenesis of PVOD and to find potential drug targets for PVOD.

Long-Term Outcome Comparison Between Two Specimen Extraction Approaches for Middle Rectum Cancer: A Retrospective Study.

. There are few studies comparing the long-term results of natural orifice specimen extraction surgery (NOSES) and conventional laparoscopic-assisted resection (LA) in the treatment of middle rectal cancer. This retrospective analysis aimed to evaluate the reliability of NOSES.

Inequalities in Cervical Cancer Screening Uptake Between Chinese Migrant Women and Local Women: A Cross-Sectional Study.

Introduction: Uptake of cervical cancer screening services in Chinese migrant workers is unknown and may be lower than non-migrant workers in China.

Methods: We conducted a cross-sectional study among migrant and non-migrant women aged 21-65 at 7 provinces across China and administered a questionnaire investigating knowledge and attitudes regarding cervical cancer, human papillomavirus (HPV), and HPV vaccine. We used multivariable logistic regression to evaluate odds of previous cervical cancer screening in migrant workers.

Extraosseous Ewing Sarcoma of the Cervical Esophagus: Case Report and Literature Review.

This study presents a case of Extraosseous Ewing sarcoma arising in the cervical esophagus of a 36-year-old woman who presented with cervical mass and dysphagia. Imaging studies demonstrated a well-defined, cystic-solid mass in the neck extending into the upper mediastinum, which results in deviation of the trachea and esophagus. The relationship between the tumor and the cervical esophagus was found in the operation.
