Endoscopic techniques have been widely used in orthopedic surgery, such as arthroscopy and transforaminal endoscopy, but the application in fracture is rarely reported. We reported a case of a 69-year-old male with pelvic fracture (AO/OTA type B2.1) who underwent successful laparoscopy-assisted pubic ramus plate fixation without auxiliary incision.

A New Hybrid Quantitative Evaluation Model for Axillary Junctional Hemorrhage in Swine.

In this study, we developed and validated a hybrid quantitative model for simulating upper extremity junctional hemorrhage in swine, aiming to advance the development of pre-hospital hemostatic products. Utilizing 12 healthy 8-month-old male Yorkshire swine, we demonstrated the feasibility of a swine axillary artery injury model for evaluating hemostatic efficacy. Animals were divided into three groups to undergo volume-controlled hemorrhage (VCH), mimicking Class I-III hemorrhagic shock by withdrawing blood at different rates.

Total, dietary, and supplemental calcium intake and risk of all-cause, cardiovascular, and cancer mortality among U.S. adults: a prospective cohort study from the National Health and Nutrition Examination Survey.

Unlabelled: Calcium intake is widely recommended, but its association with mortality remains unclear. This study indicated higher levels of calcium intake were associated with lower mortality in American adults. However, a nonlinear association between calcium intake and mortality suggested that excessive calcium intake beyond a certain threshold may increase mortality risk.

Association of dietary carbohydrate intake with bone mineral density, osteoporosis and fractures among adults without diabetes: Evidence from National Health and Nutrition Examination Survey.

Background: The impact of dietary carbohydrate intake on bone health remains a subject of controversy, potentially influenced by individuals with diabetic osteoporosis who exhibit normal or elevated bone mineral density (BMD). The cross-sectional study was conducted to explore the association between carbohydrate intake and BMD, osteoporosis and fractures among adults without diabetes, based on the National health and nutrition examination survey (NHANES).

Methods: Participants were from the NHANES 2005-2010, excluding individuals with diabetes and those with incomplete data.

Experimental and Theoretical Research on Photocatalytic Nitrogen Reduction Using MoS Nanosheets with Polysulfide Vacancies.

MoS nanosheets with different concentrations of S vacancies (V-MoS) were synthesized and used for photocatalytic nitrogen reduction reactions (pNRR), and the mechanism of S vacancies enhancing the activity of MoS was explored through DFT calculation. The material characterization confirmed the successful construction of S vacancies at different concentrations on the spherical cluster structure of MoS. The experimental results show that the introduction of S vacancies significantly improves the activity of pNRR, and it increases significantly with the increase of vacancy number, consistent with the trend of photoelectric performance.

Biodegradable and flame-retardant cellulose-based wearable triboelectric nanogenerator for mechanical energy harvesting in firefighting clothing.

Integrating flexible triboelectric nanogenerators (TENGs) into firefighting clothing offers exciting opportunities for wearable portable electronics in personal protective technology. However, it is still a grand challenge to produce eco-friendly TENGs from biodegradable and low-cost natural polymers for mechanical-energy harvesting and self-powered sensing. Herein, conductive polypyrrole (PPy) and natural chitosan (CS)/phytic acid (PA) tribonegative materials were employed onto the Lycra fabric (LC) in turn to assemble the biodegradable and flame-retardant single-electrode mode LC/PPy/CS/PA TENG (abbreviated as LPCP-TENG).

Cytokine Biomarker Phenotype for Early Prediction and Triage of Sepsis in Blunt Trauma Patients.

Background: Altered levels of inflammatory markers secondary to severe trauma present a major problem to physicians and are prone to interfering with the clinical identification of sepsis events. This study aimed to establish the profiles of cytokines in trauma patients to characterize the nature of immune responses to sepsis, which might enable early prediction and individualized treatments to be developed for targeted intervention.

Methods: A 15-plex human cytokine magnetic bead assay system was used to measure analytes in citrated plasma samples.

A comprehensive investigation on cellulose nanocrystals with different crystal structures from cotton via an efficient route.

The crystal structures of cellulose nanomaterials play an important role in their morphologies and applications, however, there was still lacking systematic research on preparing various crystalline allomorphs of cellulose nanocrystals with high thermal stability. Herein, the efficient synthesis route was presented to design various crystalline allomorphs of cellulose from cotton. And then, cellulose nanocrystals with different crystal structures (CNC-I, CNC-II, CNC-III, CNC-IV) were prepared by hydrogen peroxide hydrolysis of resultant cellulose.

Polygenic Risk Score for Early Prediction of Sepsis Risk in the Polytrauma Screening Cohort.

Background: Increasing genetic variants associated with sepsis have been identified by candidate-gene and genome-wide association studies, but single variants conferred minimal alterations in risk prediction. Our aim is to evaluate whether a weighted genetic risk score (wGRS) that aggregates information from multiple variants could improve risk discrimination of traumatic sepsis.

Methods: Sixty-four genetic variants potential relating to sepsis were genotyped in Chinese trauma cohort.

Experimental and Theoretical Investigations into the Performance and Mechanism of CO Capture by 3D and 2D ZnAl Layered Double Hydroxides.

Two-dimensional (2D) materials have a wide range of applications in adsorption and catalysis because of their high specific surface areas and large number of surface active sites. In this paper, bulk ZnAl layered double hydroxides (ZnAl-LDHs or bulk-LDHs) and 2D monolayer ZnAl-LDHs (monolayer-LDHs) were constructed and used for CO capture at temperatures of 298-573 K. The experimental results show that monolayer-LDHs have a large specific surface area (455 m g) and shows an excellent CO capture performance (4.
