Artificial Intelligence-Based Prediction of Lower Extremity Deep Vein Thrombosis Risk After Knee/Hip Arthroplasty.

Deep vein thrombosis (DVT) is a common postoperative complication of knee/hip arthroplasty. There is a continued need for artificial intelligence-based methods of predicting lower extremity DVT risk after knee/hip arthroplasty. In this study, we performed a retrospective study to analyse the data from patients who underwent primary knee/hip arthroplasty between January 2017 and December 2021 with postoperative bilateral lower extremity venous ultrasonography.

Dynamic Visual Acuity After Small Incision Lenticule Extraction for Myopia Patients.

In the present study we compared dynamic visual acuity (DVA) of 84 eyes (for 42 adults with myopia; age = 28.4, = 6.6 years; males = 38.

The Association Between High-Sensitivity C-Reactive Protein/Albumin Ratio and Cardiovascular Prognosis in Patients Undergoing Percutaneous Coronary Intervention.

Limited studies have focused on the impact of high-sensitivity C-reactive protein (hsCRP) to albumin ratio (CAR) on cardiovascular outcomes in patients undergoing percutaneous coronary intervention (PCI). Hence, the present study evaluates the association between CAR and cardiovascular outcomes in patients undergoing drug-eluting stent (DES) implantation. We consecutively enrolled 9375 CHD patients undergoing DES implantation.

A study on the correlation of placental characteristics and the onset of selective intrauterine growth restriction.

Objective: To investigate the correlation between placental characteristics and the onset of selective intrauterine growth restriction (sIUGR) and to explore the influence of placental characteristics on sIUGR onset.

Methods: A retrospective cohort study was conducted at our hospital from April 2013 to April 2019. The pregnancy data and placental perfusion of 114 sIUGR patients who had received conservative treatment and delivered in our hospital were included.

The Supportive Role of International Government Funds on the Progress of Sepsis Research During the Past Decade (2010-2019): A Narrative Review.

This narrative review aimed to clarify the characteristics of international government support for sepsis research, trends in published literature on sepsis, and potential contributions of government-source grants to progress in sepsis research between fiscal years 2010 and 2019. The data in this study were collected from the National Institutes of Health (NIH, https://projectreporter.nih.

Prevalence and Risk Factors of Dry Eye Symptoms after Successful Dacryocystorhinostomy for Patients with Lacrimal Passage Obstruction.

Purpose: To investigate the prevalence of dry eye symptoms after successful dacryocystorhinostomy and explore the potential risk factors.

Methods: This cross-sectional study included 565 patients with lacrimal passage obstruction (LPO) who underwent external dacryocystorhinostomy. Ocular Surface Disease Index (OSDI) total score of 13 or more was regarded as presence of dry eye symptoms.

Pipeline for the treatment of distal cerebral circulation aneurysms: A multicenter study focusing on periprocedural Complications.

Background And Aim: Distal cerebral circulation aneurysms (DCCAs) remain treatment challenges for neurointervention. The off-label use of the pipeline embolization device (PED) for these aneurysms remains controversial. This study aimed to evaluate the safety and efficacy of PED for DCCAs in a multicenter cohort of patients.

Assessment of temporal and spatial distribution patterns of aerosol produced by air-puff non-contact tonometer.

Purpose: To assess the distribution pattern of aerosol in the aspect of time and direction during the intraocular pressure (IOP) measurement by air-puff non-contact tonometer (NCT) and further offer references for protection from coronavirus disease-19 (COVID-19) in the routine ophthalmic examination.

Method: A single-center observational study was conducted in the ophthalmology clinics of Peking University Third Hospital. Two air quality detectors were equipped to assess the generated particulate matter (PM) concentration simultaneously within 30 s after IOP measurement in the outpatient hall.

Evaluation of Adjacent Segment With Pre-Existing Degeneration Using the Cerebrospinal Fluid Occlusion Sign on MRI Before Posterior Lumbar Fusion: A Multi-Center Observational Cohort Study.

Study Design: Prospective cohort study.

Objective: To evaluate whether pre-existing adjacent spinal canal stenosis (SCS) is associated with short-term outcomes after lumbar fusion surgery.

Methods: We included patients with lumbar spinal stenosis treated surgically between July 2015 and December 2017 at 4 centers.

Percutaneous Kyphoplasty Versus Percutaneous Vertebroplasty for Neurologically Intact Osteoporotic Kümmell's Disease: A Systematic Review and Meta-Analysis.

Study Design: Systematic review and meta-analysis.

Objective: Percutaneous vertebroplasty (PVP) and percutaneous kyphoplasty (PKP) are minimally invasive techniques widely used for the treatment of neurologically intact osteoporotic Kümmell's disease (KD), but which treatment is preferable remains controversial. Therefore, this study aimed to shed light on this issue.

Comparison of Anterior Approach and Posterior Circumspinal Decompression in the Treatment of Giant Thoracic Discs.

Study Design: Retrospective cohort study.

Objectives: The treatment of giant thoracic disc herniation (gTDH)remains challenging for surgeons worldwide because of its large volume and calcified or ossified nature and the limitations of the prior small-sample-size, single-center studies reporting comparative effectiveness. We aim to compare the anterior decompression and spinal fusion (ASF) and posterior circumspinal decompression and spinal fusion (PCDF) for patients with myelopathy due to gTDH in the largest study to date by sample size.

Inhibition of osteoblast proliferation and migration by exogenous and endogenous formaldehyde.

Exogenous and endogenous formaldehyde (FA) both play an important role in cell growth and migration; however, their potential role in osteoblasts remains largely unclear. Cell counting kit-8 (CCK-8) and wound-healing assays revealed that FA exposure at naturally occurring concentrations inhibited the proliferation and migration of mouse preosteoblast MC3T3-E1 cells. Moreover, RNA sequencing (RNA-seq) analysis revealed that FoxO1 signaling pathway components displayed distinct expression patterns upon FA exposure, reflected through significant enrichment of cell migration.

One-year outcomes of radiofrequency ablation of incompetent perforator veins using the radiofrequency stylet device: Cohort study from East Asia.

Objectives: The present study was designed to assess outcomes of patients undergone radiofrequency ablation (RFA) for their incompetent perforator veins (IPVs) with ClosureFast stylets.

Methods: Data of 165 IPVs in 138 limbs of 117 consecutive patients between July 2017 to Nov. 2019 were retrospectively reviewed.

The Preliminary Results of 3-Dimensional Printed Individual Template Assisted 192Ir High-Dose Rate Interstitial Brachytherapy for Central Recurrent Gynecologic Cancer.

Objective: To evaluate the feasibility and safety of high dose rate interstitial brachytherapy (HDR-IB) assisted with 3-dimensional printing individual template (3D-PIT) for central pelvic recurrent gynecologic cancer (CR-GYN).

Methods: Totally 32 patients diagnosed with CR-GYN received iridium-192(192Ir) HDR-IB assisted with 3D-PIT that was classified in 2 types(Type I: transvaginal template/ applicator, and Type II: transvaginal combined transperineal template). The prescribed dose to gross tumor volume (GTV) was 10-36 Gy in 2-6 fractions.

Changing Trends of Color of Different Laryngeal Regions in Laryngopharyngeal Reflux Disease.

Introduction: In our previous study, we demonstrated that there might be correlations between laryngopharyngeal reflux disorder and the hue value of laryngoscopic images. And we found that different regions of larynx have different hue values. It was hypothesized that the degree of inflammation varies between different laryngeal regions, due to an acid reflux pattern.
