Article Synopsis
  • - The study investigates a new surgical tool designed to improve the placement of pedicle screws in adolescent idiopathic scoliosis operations, aiming to reduce the risk of damaging surrounding blood vessels and nerves.
  • - A retrospective analysis was conducted on 24 adolescent patients, comparing outcomes between those using the postural awareness tool and those using a traditional freehand technique during surgery.
  • - Results showed that the postural awareness group had shorter operative times, less blood loss, and higher screw placement accuracy (91.41%) compared to the C-arm group (83.02%), indicating the tool's effectiveness in enhancing surgical outcomes.

Article Synopsis
  • - The study was a retrospective cohort analysis aimed at assessing the effectiveness of a new technique called tandem growth rod (GR) versus traditional GR for treating severe early-onset scoliosis (EOS).
  • - In the tandem GR group, patients showed significantly improved control over the secondary curve and better overall growth, with lower angles on clavicular measurements and higher T1-S1 height compared to those treated with traditional GR.
  • - The results indicate that tandem GR not only improves spinal curvature and shoulder balance but also promotes better longitudinal growth in patients with EOS.

This study describes a novel species of (Squamata: Gekkonidae) based on its distinct morphological features and molecular evidence, which was identified in the Dabie Mountains on the border of Anhui and Henan provinces of Central China. could be distinguished from its congeners owing to its morphological characteristics, such as being a medium body sized gecko species (snout-vent length, 56.98-64.

Environmental noise has a significant negative impact on acoustic communication in most situations, as it influences the production, transmission, and reception of acoustic signals. However, how animals respond to conspecific sounds when there is interference from environmental noise, and whether males and females display convergent behavioral responses in the face of noise masking remain poorly understood. In this study, we investigated the effects of conspecific male advertisement calls with different signal-to-noise ratios on male-male competition and female choice in the Anhui tree frog using playback and phonotaxis experiments, respectively.

Background: Cooperation between China and Africa is deepening, and business, trade, and people-to-people exchanges are growing closer together, especially in the infrastructure construction field. At the same time, malaria has become a serious health concern for Chinese construction workers in Africa, who are at increased risk of infection and complications due to lack of immunity and exposure to high-transmission environments. One of the biggest challenges in fighting malaria is their lack of knowledge and misinterpretations about the disease, which can impact their need for interventions, adherence to treatments, and health services.

BACKGROUND Epithelioid sarcoma is rare, represents less than 1% of all sarcomas, usually occurs in the extremities, and rarely presents as a primary sarcoma of the spine. Publications are usually single reports or case series. We aimed to undertake a systematic review of publications of cases of primary epithelioid sarcoma of the spine to evaluate clinical presentation, diagnosis, management, and patient outcomes.

Objective: To compare the clinical and radiological outcomes of minimally invasive transforaminal lumbar interbody fusion (MIS-TLIF) and traditional open transforaminal lumbar interbody fusion (OPEN-TLIF) in the treatment of two-level lumbar degenerative diseases. Methods: The clinical data of 112 patients were retrospectively analyzed, and were divided into an MIS-TLIF group and OPEN-TLIF group. The operative time, intraoperative fluoroscopy, blood loss, postoperative drainage volume, bed rest time, the content of creatine kinase(CK) and complications, were recorded.

Species belonging to the genus are small-sized frogs that are widely distributed in southern, eastern, and south-eastern Asia. In China, the genus harbors many cryptic species, on two of which- and -studies were recently published. In this study, we collected specimens from the Dabie Mountain range, which is at the junction of Anhui, Henan and Hubei Provinces, East China; these specimens belonged to a species previously identified as .

The direct Z-scheme van der Waals (vdW) heterojunctions based on biomimetic artificial photosynthesis are a promising strategy for enhancing photocatalytic activity. Therefore, the search for superior direct Z-scheme photocatalysts is an urgent task. Herein, we predicted the WSeTe/ZrCO heterostructure as a potential direct Z-scheme photocatalyst based on density functional theory (DFT).

Purpose: To retrospectively evaluate the characteristics of spino-pelvic parameters after long-segment fixation in patients with Lenke-Silva type 5 or 6 adult degenerative scoliosis and analyze the correlation between spino-pelvic parameters and health-related quality of life (HRQL).

Methods: Thirty-two patients with degenerative scoliosis underwent long-segment posterior fixation were included. The spino-pelvic parameters were evaluated after surgery, and the HRQL scores were determined using the Scoliosis Research Society-22 (SRS-22), Oswestry Disability Index (ODI), and visual analog scale (VAS).

This paper proposes a novel floating high-voltage level shifter (FHV-LS) with the pre-storage technique for high speed and low deviation in propagation delay. With this technology, the transmission paths from input to output are optimized, and thus the propagation delay of the proposed FHV-LS is reduced to as low as the sub-nanosecond scale. To further reduce the propagation delay, a pull-up network with regulated strength is introduced to reduce the fall time, which is a crucial part of the propagation delay.

Background: This meta-analysis was performed to incorporate newly published, high-quality randomized controlled trials (RCTs) to determine the effects of cemented versus uncemented hemiarthroplasty for elderly patients with displaced fracture of the femoral neck.

Methods: The following electronic databases were extensively searched from the inception of the database through December 2018: EMBASE, Medline, the Cochrane Library, and Web of Science. RCTs focusing on the outcomes of cemented and uncemented hemiarthroplasty were reviewed and screened for eligibility.

Background: Non-muscle invasive bladder cancer (NMIBC) is the most common bladder cancer. Many studies have reported that intra-arterial chemotherapy (IAC) combined with intravesical chemotherapy (IVC) could effectively reduce the recurrence rate of NMIBC. The purpose of this study is to assess the efficacy and safety of IAC combined with IVC for patients with high-risk NMIBC.
