Comprehensive assessment of risk factors and development of novel predictive tools for perioperative hidden blood loss in intertrochanteric femoral fractures: a multivariate retrospective analysis.

Objectives: To identify independent risk factors for perioperative hidden blood loss (HBL) in intertrochanteric femoral fractures (ITFs) and to develop a predictive model.

Methods: We enrolled 231 patients with ITFs who underwent proximal femoral nail antirotation (PFNA) surgery at the Orthopedics Department of Northern Jiangsu People's Hospital, Jiangsu Province, China, from January 2021 to December 2023. Hidden blood loss was calculated using the OSTEO formula, and independent risk factors were screened using the Least Absolute Shrinkage and Selection Operator (LASSO) logistic regression.

Evaluation of two luteal support regimens, intramuscular progesterone and progesterone vaginal gel, for vitrified-warmed embryo transfer in women with chronic salpingitis: a single-center 8-year retrospective study.

Background: Chronic salpingitis is one of the most common causes of female infertility. Luteal support is a critical step for embryo transfer. Here, we evaluated the effects of two luteal support regimens, intramuscular progesterone (IMP) and progesterone vaginal gel (VAG), on the pregnancy outcomes in patients with chronic salpingitis undergoing vitrified-warmed embryo transfer.

The regular effects of concurrent aerobic and resistance exercise on global cognition in healthy elderly populations: A systematic review with meta-analysis of randomized trials.

Aerobic and resistance exercises are widely recognized as essential for preserving and enhancing cognitive function. However, the effects of concurrent exercise on cognition in older adults remain unclear. This systematic review sought to evaluate the regular effects of concurrent aerobic and resistance training on global cognition in healthy older adults.

Gut Microbiota: A Modulator and Therapeutic Target for Chronic Pain.

Chronic pain is a prevalent condition, impacting nearly one-fifth of the global population. Despite the availability of various clinical treatments, each comes with inherent limitations, and few offer a complete cure, resulting in a significant social and economic burden. Therefore, it is important to determine the pathogenesis and causes of chronic pain.

Multimodal profiling uncovers tertiary lymphoid structures as a critical determinant of immunotherapy response and prognosis in nasopharyngeal carcinoma.

Nasopharyngeal carcinoma (NPC), historically termed 'lymphoepithelioma-like carcinoma' due to its rich lymphocyte infiltration, benefit from PD-1 blockade treatment. However, a comprehensive understanding of its tumor microenvironment (TME) remains elusive, hindering the identification of effective biomarkers for immunotherapy. We leveraged multimodal profiling data, including gene expression, immunohistochemistry, and multiplex immunohistochemistry, from three independent cohorts of NPC patients with a total of 327 patients to dissect the TME in NPC.
