Objective: To investigate the effects of modified twin-block appliances (MTBA) on obstructive sleep apnea (OSA) and mandibular retrognathia and the changes in the upper airway, hyoid bone position, and hypoxia-related inflammatory marker levels in children with OSA.

Methods: This study included children with OSA and mandibular retrognathia and those with class I without mandibular retrognathia (n = 35 each). The experimental group comprised children with OSA and mandibular retrognathia managed using MTBA.

Article Synopsis
  • Uterine carcinosarcoma (UCS) is a rare cancer combining both carcinoma and sarcoma features, often resembling endometrial carcinoma, with a potential link to nulliparity (never having given birth) as a risk factor.
  • A 55-year-old woman presented with postmenopausal vaginal bleeding and was diagnosed after surgery, revealing well-differentiated adenocarcinoma and osteosarcoma components, along with multiple positive immunohistochemical markers.
  • Following a series of surgical interventions and treatments, including chemotherapy and radiotherapy, the patient demonstrated no signs of tumor recurrence and had a disease-free survival of seven months as of July 2024.

Background: Fetal intracranial volume (ICV) can help evaluate the development of the prenatal central nervous system (CNS) from the three-dimensional (3D) attributes of the cranial structure. Accurate and rapid segmentation and calculation of the ICV are clinically significant. Virtual organ computer-aided analysis (VOCAL) is a commonly used method for measuring fetal ICV.

Background: Gallbladder cancer (GBC) was once considered a contraindication for laparoscopic surgery, but it is becoming more common to use laparoscopic surgery for GBC treatment. The aim of this study was to analyze the long- and short-term outcomes of patients with more advanced T-staged GBC treated with curative intent as defined by the National Comprehensive Cancer Network (NCCN) after laparoscopic resection (LR) versus open resection (OR).

Methods: A multicenter database was used to select consecutive GBC patients treated with curative-intent resection as defined by the NCCN between 2016 and 2020.

Introduction: Observational studies have shown a bidirectional association between gastroesophageal reflux (GER) and chronic rhinosinusitis (CRS) or chronic rhinitis (CR), but it is not clear whether this association is causal.

Objectives: This study was to investigate the causality between GER and CRS or CR using bidirectional two-sample Mendelian randomization (MR) analysis.

Methods: Using pooled data from large genome-wide association studies (GWAS), genetic loci independently associated with GER, CRS and CR in populations of European and American ancestry were selected as instrumental variables (IVs).

Article Synopsis
  • The study investigates how to improve adhesion between poly(tetrafluoroethylene-co-hexafluoropropylene) (FEP) films and silver coatings through surface activation.
  • Chemical activation using a naphthalene sodium solution is highlighted as an effective method, though its impact on the resulting interface has not been widely studied.
  • Experimental results reveal that oxygen-containing functional groups created during activation enhance interaction with silver, and optimal adhesion is achieved at a high naphthalene sodium concentration, a medium activation time, and a high winding speed during silver deposition.

Objective: This study explored the characteristics of fetal mesenteric blood flow perfusion across various gestational weeks and evaluated the efficacy of Microvascular Flow (MV-Flow) imaging technology in assessing intestinal wall blood flow in fetuses with meconium peritonitis (MP).

Method: In this retrospective study, we analyzed 35 fetuses with MP and 160 healthy fetuses. We examined the correlation between the Vascular Index (VI) of mesenteric perfusion and gestational age, conducted an analysis comparing MP operative and non-operative groups, and developed a predictive model for surgical intervention.

The objective of this study was to investigate the association between pre-operative body mass index (BMI) and surgical infection in perihilar cholangiocarcinoma (pCCA) patients treated with curative resection. Consecutive pCCA patients were enrolled from four tertiary hospitals between 2008 and 2022. According to pre-operative BMI, the patients were divided into three groups: low BMI (≤18.

The amount of genetic data generated by Next Generation Sequencing (NGS) technologies grows faster than Moore's law. This necessitates the development of efficient NGS data processing and analysis algorithms. A filter before the computationally-costly analysis step can significantly reduce the run time of the NGS data analysis.

Background: The prognostic value of carbohydrate antigen 19-9 (CA19-9) is known to be affected by elevated bilirubin levels in patients with gallbladder carcinoma (GBC). The clinical significance of changes in the ratio of CA19-9 levels to total bilirubin (TB) levels in patients with GBC after curative-intent resection remains unknown. The aim of this study was to determine the prognostic value of changes in preoperative and postoperative CA19-9/TB ratio in these patients.

Objective: To investigate changes in the upper maxillary palates of children with obstructive sleep apnoea (OSA) and mandibular retraction who were treated using modified twin-block appliances (MTBAs).

Methods: Thirty-five OSA children (age: 6-12 years) with mandibular retraction were included as the experimental group and 35 children who were Angle's class I but without mandibular retraction were included as the control group. The experimental group was treated with MTBA.

Developing a self-elastic sponge integrating active and passive hemostatic mechanisms for the effective management of uncontrolled coagulopathic hemorrhage remains a challenge. We here developed a chitosan-based sponge by integrating freeze-drying, chemical decoration of alkyl chains and phosphate groups, and physical loading of thrombin. The sponge exhibited high mechanical strength, self-elasticity, and rapid shape recovery.

In this study, the traditional mini split Hopkinson tension bar (SHTB) was enhanced for the dynamic mechanical performance testing of single fiber/resin interface of composites. Single Aramid III fibers were modified using a polyamine modification treatment. Quasi-static and dynamic tensile tests of modified single Aramid III fibers were conducted using an electronic tensile testing machine and mini SHTB.

Objective: To investigate the diagnostic utility of multimodal ultrasound for fetal bowel dilatation (FBD) in different parts of the bowel and to examine its prognostic potential in FBD.

Methods: This retrospective study analyzed 86 fetuses with a dilated bowel identified via ultrasound in a 10-month postnatal follow-up. Both two- and three dimensional (2D and 3D, respectively) ultrasound volume imaging were used to characterize dilation across different bowel sections.

Article Synopsis
  • Primary gastrointestinal follicular lymphoma (PGI-FL) is a rare type of lymphoma with unclear epidemiology and prognosis, studied in a large analysis of patients using the SEER database.
  • The average annual incidence of PGI-FL is low, but patients with PGI-FL have a longer median overall survival compared to those with nodal follicular lymphoma (N-FL) and a lower risk of transformation to diffuse large B-cell lymphoma (DLBCL).
  • Predictive nomograms were created to help estimate patient survival and classify patients into three risk groups for better treatment planning and personalized care.

Objective: To analyze the clinical characteristics of laryngomalacia in Chinese children and explore the surgical efficacy and factors influencing severe laryngomalacia.

Methods: Children (0-18 years) diagnosed with laryngomalacia in our hospital from January 2016 to January 2022 were enrolled in this study. Clinical data of patients, including general conditions, clinical symptoms, grading and classification, medical comorbidities, surgical efficacy, and the risk factors influencing severe laryngomalacia were retrospectively analyzed.

Spiking neural network (SNN) simulators play an important role in neural system modeling and brain function research. They can help scientists reproduce and explore neuronal activities in brain regions, neuroscience, brain-like computing, and other fields and can also be applied to artificial intelligence, machine learning, and other fields. At present, many simulators using central processing unit (CPU) or graphics processing unit (GPU) have been developed.
