A 53-year-old patient with a history of Loeys-Dietz syndrome (LDS) presented with cutout after a right femoral neck fracture treated with a dynamic hip screw. This was treated with conversion total hip arthroplasty (THA), the second reported THA in a patient with LDS and the first in a post-traumatic reconstruction setting. The patient had 2 episodes of posterior hip dislocations within 2 weeks after the operation requiring a revision THA utilizing dual-mobility bearing to achieve stability. LDS is a connective-tissue disorder that is associated with joint hypermobility and spinal deformities, among other features. These factors can affect hip pathology, approaches to treatment, and outcomes. Patients with LDS should have a comprehensive musculoskeletal evaluation and history such as those with Marfan syndrome or Ehlers-Danlos syndrome, especially if undergoing THA. Further research on the implications of LDS on the hip and spine should be performed.

Background: Preoperative neoadjuvant chemoradiotherapy (nCRT) is considered to be the standard treatment strategy for locally advanced rectal cancer (LARC); however, the risk of adverse events and postoperative recurrence remains significant. This study aimed to evaluate the non-inferiority of neoadjuvant chemotherapy (nCT) compared with nCRT in patients with LARC and to assess the possibility of eliminating radiotherapy on the basis of guaranteed efficacy.

Materials And Methods: We searched the PubMed, Embase, and Cochrane Library databases to identify randomized controlled trials (RCTs) comparing the efficacy of nCRT and nCT for LARC.

Objective: This study aimed to uncover the patterns of Human papillomavirus (HPV) infection outcomes in women and assess the risk factors that may affect these outcomes.

Methods: A retrospective study was conducted on 608 women who tested positive for HPV-DNA during their initial visit to the outpatient department of Shenzhen Longgang Central Hospital from 2018 to 2023 and who had subsequent HPV-DNA testing as part of their post-visit monitoring. The monitoring intervals were every 6 months.

Goal: Cost-saving initiatives targeting surgical supplies management have become increasingly common to address rising healthcare costs. However, few studies provide details on hospital stakeholder experiences or learnings from implementing such initiatives. Thus, we sought to evaluate hospital stakeholder satisfaction with conversion to a sole supplier for hemostasis products, in addition to economic and clinical impacts, to help develop best practices for implementation.

Metamaterials hold great promise for application in the field of perfect absorbers due to their remarkable ability to manipulate electromagnetic waves. In this work, a full-spectrum ultra-wideband solar absorber with a multilayer metal-dielectric stacked structure is designed. Our absorber is simple and easy to manufacture, with Ti serving as the substrate, overlaid with SiN spacer layers and four pairs of Ti-SiN ring columns.
