Intraoperative Femoral Fractures During Primary Total Hip Arthroplasty are Associated with Increased Revision and Complication Rates.

Background: Intraoperative femoral fractures are a rare, but serious complication of primary total hip arthroplasty (THA), and little is known about the rates of complications and reoperations in these patients. The objective of this investigation was to describe the two-year outcomes and revision rates in patients who sustain an intraoperative femoral fracture during THA.

Methods: A large administrative claims database was queried for patients who sustained an intraoperative femoral fracture during primary and elective THA from 2015 to 2022.

Subspecies phylogeny in the human gut revealed by co-evolutionary constraints across the bacterial kingdom.

The human gut microbiome contains many bacterial strains of the same species ("strain-level variants") that shape microbiome function. The tremendous scale and molecular resolution at which microbial communities are being interrogated motivates addressing how to describe strain-level variants. We introduce the "Spectral Tree"-an inferred tree of relatedness built from patterns of co-evolutionary constraint between greater than 7,000 diverse bacteria.

Fiber- and acetate-mediated modulation of MHC-II expression on intestinal epithelium protects from Clostridioides difficile infection.

Here, we explore the relationship between dietary fibers, colonic epithelium major histocompatibility complex class II (MHC-II) expression, and immune cell interactions in regulating susceptibility to Clostridioides difficile infection (CDI). We find that a low-fiber diet increases MHC-II expression in the colonic epithelium, which, in turn, worsens CDI by promoting the development of pathogenic CD4 intraepithelial lymphocytes (IELs). The influence of dietary fibers on MHC-II expression is mediated by its metabolic product, acetate, and its receptor, free fatty acid receptor 2 (FFAR2).

Neonatal cost savings in hypertensive disorders of pregnancy: Economic evaluation of the sFlt-1/PlGF test with real world implementation of biomarkers.

Background: Preeclampsia is a key cause of prematurity in the U.S. and incurs significant healthcare costs.

From waste to Innovation: Silver-Doped silicate ink coating from waste coal fly ash for hydrophobic antimicrobial fabric and Water-Oil separation.

Coal fly ash, a waste byproduct of coal-fired power plants rich in silica, is produced in vast quantities, exceeding 750 million tons annually. This abundance underscores the importance of finding sustainable and value-added applications for its reuse. Silver nanoparticle-silica composites represent a class of inorganically hybrid antimicrobial agents as the protection layer of cotton fabrics.

Pediatric Robotic-assisted Laparoscopic Pyeloplasty: Defining Mastery Over a 15 Year Experience.

Background: Robotic-assisted laparoscopic pyeloplasty (RALP) has been widely utilized within pediatric urology as RALP provides additional advantages to laparoscopic pyeloplasty including a more manageable learning curve. We aim to describe the maturation and mastery of pediatric RALP through our proposed trifecta of operative time, complication rates, and surgical success rates.

Methods: We retrospectively reviewed 148 patients who underwent RALP between 2007 and 2022.

Situating the salience and parietal memory networks in the context of multiple parallel distributed networks using precision functional mapping.

Brain networks serving higher cognitive functions are widely distributed across frontal and posterior association zones. Two exceptions have been the parietal memory network (PMN) and salience network (SAL), which are typically restricted to posterior (e.g.

Examining Electronic Nicotine Delivery System (ENDS) Cue Reactivity Using a Remote Platform: Cigarette and ENDS Desire in Dual Users.

Introduction: Prior research shows that in-person exposure to electronic nicotine delivery systems (ENDS) use increases desire for cigarettes and ENDS. However, less is known about the impact of cues delivered during remote interactions. This study extends previous in-person cue work by leveraging a remote confederate-delivered cue-delivery paradigm to evaluate the impact of dual nicotine vaping (vs.

Peripheral T-Cell Lymphoma-NOS in Children and Adolescents: a Review from the Children's Oncology Group NHL Committee.

Peripheral T-cell lymphoma-not otherwise specified (PTCL-NOS) is a rare mature T-cell non-Hodgkin lymphoma (NHL) seen in both children and adults. While it is the most common non-anaplastic mature T-cell lymphoma of childhood, it is quite rare and therefore, the standard of care remains largely undefined. It is a disease characterized by clinical and pathological heterogeneity and is generally associated with an aggressive clinical course and poor prognosis in adults.

New onset refractory status epilepticus: Long-term outcomes beyond seizures.

We propose and prioritize important outcome domains that should be considered for future research investigating long-term outcomes (LTO) after new onset refractory status epilepticus (NORSE). The study was led by the international NORSE Institute LTO Working Group. First, literature describing the LTO of NORSE survivors was identified using a PubMed search and summarized to identify knowledge gaps.

Examining eating pathology and psychosocial functioning across subjective eating disorder recovery stages in sexual and gender minority individuals.

Subjective eating disorder (ED) recovery has important clinical relevance. However, studies have focused on the perspectives of cisgender heterosexual individuals, which is notable given that sexual and gender minority (SGM) people often describe feelings misrepresented by prevailing ED conceptualizations. We examined eating pathology and psychosocial functioning across subjective recovery stages in SGM individuals ( = 196).

Data-Driven Equation-Free Dynamics Applied to Many-Protein Complexes: The Microtubule Tip Relaxation.

Microtubules (MTs) constitute the largest components of the eukaryotic cytoskeleton and play crucial roles in various cellular processes, including mitosis and intracellular transport. The property allowing MTs to cater to such diverse roles is attributed to dynamic instability, which is coupled to the hydrolysis of GTP (guanosine-5'-triphosphate) to GDP (guanosine-5'-diphosphate) within the β-tubulin monomers. Understanding the equilibrium dynamics and the structural features of both GDP- and GTP-complexed MT tips, especially at an all-atom level, remains challenging for both experimental and computational methods because of their dynamic nature and the prohibitive computational demands of simulating large, many-protein systems.

Hypertensive disorders of pregnancy and gestational diabetes mellitus and predicted risk of maternal cardiovascular disease 10-14 years after delivery: A prospective cohort.

Aims: Studies evaluating the relationship between adverse pregnancy outcomes (APOs), namely hypertensive disorders of pregnancy (HDP) and gestational diabetes mellitus (GDM), with the estimated risk of atherosclerotic cardiovascular disease (ASCVD) remains limited and could inform patient-centred decision-making in the postpartum period. We examined whether HDP or GDM were associated with a higher 10- and 30-year predicted risk of ASCVD measured 10-14 years after delivery.

Methods: A secondary analysis from the international prospective Hyperglycemia and Adverse Pregnancy Outcome Follow-up Study (2013-2016) cohort.

Enriched phenotypes in rare variant carriers suggest pathogenic mechanisms in rare disease patients.

Background: The mechanistic pathways that give rise to the extreme symptoms exhibited by rare disease patients are complex, heterogeneous, and difficult to discern. Understanding these mechanisms is critical for developing treatments that address the underlying causes of diseases rather than merely the presenting symptoms. Moreover, the same dysfunctional series of interrelated symptoms implicated in rare recessive diseases may also lead to milder and potentially preventable symptoms in carriers in the general population.

Intercellular TIMP-1-CD63 signaling directs the evolution of immune escape and metastasis in KRAS-mutated pancreatic cancer cells.

Background And Aims: Oncogenic KRAS mutations are present in approximately 90% of pancreatic ductal adenocarcinoma (PDAC). However, Kras mutation alone is insufficient to transform precancerous cells into metastatic PDAC. This study investigates how KRAS-mutated epithelial cells acquire the capacity to escape senescence or even immune clearance, thereby progressing to advanced PDAC.

Targeting unique ligand binding domain structural features downregulates DKK1 in Y537S ESR1 mutant breast cancer cells.

Resistance to endocrine therapies remains a major clinical hurdle in breast cancer. Mutations to estrogen receptor alpha (ERα) arise after continued therapeutic pressure. Next generation selective estrogen receptor modulators and degraders/downregulators (SERMs and SERDs) show clinical efficacy, but responses are often non-durable.

Aim: This study aimed to estimate the annual cost burden of productivity loss due to sickness presenteeism among hospital nurses in South Korea.

Background: Despite nurses being potentially more vulnerable to presenteeism, few studies have analyzed nurses' productivity losses due to sickness presenteeism.

Methods: This cross-sectional study employed an online survey in January 2023 with 607 nurses working in general/tertiary hospitals in South Korea.

Evolution of the umbilical cord blood proteome across gestational development.

Neonatal health is dependent on early risk stratification, diagnosis, and timely management of potentially devastating conditions, particularly in the setting of prematurity. Many of these conditions are poorly predicted in real-time by clinical data and current diagnostics. Umbilical cord blood may represent a novel source of molecular signatures that provides a window into the state of the fetus at birth.

Changes in the potato rhizosphere microbiota richness and diversity occur in a growth stage-dependent manner.

Plant root and soil-associated microbiomes are influenced by niches, including bulk and rhizosphere soil. In this work, we collected bulk and rhizosphere soil samples at four potato developmental stages (leaf growth, flowering, tuber elongation and harvest) to identify whether rhizosphere microbiota are structured in a growth stage-dependent manner. The bacterial and fungal microbiota showed significant temporal differences in the rhizosphere and bulk soil.

A time-varying index for agricultural suitability across Europe from 1500-2000.

Throughout the last centuries, European climate changed substantially, which affected the potential to plant and grow crops. These changes happened not just over time but also had a spatial dimension. Yet, despite large climatic fluctuations, quantitative historical studies typically rely on static measures for agricultural suitability due to the non-availability of time-varying indices.
