Use of Cemented Hemiarthroplasty for Femoral Neck Fractures.

Geriatric femoral neck fractures are common orthopaedic injuries, which are associated with a high morbidity and mortality. Arthroplasty is the optimum treatment for many of these injuries, but debate exists regarding optimal surgical strategy. Multiple recent investigations have demonstrated strong superiority for cemented stems as compared with noncemented fixation with a decreased risk of periprosthetic fracture, shorter length of stay, lower cost, and decreased rate for revision surgery.

Diversification and recurrent adaptation of the synaptonemal complex in Drosophila.

The synaptonemal complex (SC) is a protein-rich structure essential for meiotic recombination and faithful chromosome segregation. Acting like a zipper to paired homologous chromosomes during early prophase I, the complex is a symmetrical structure where central elements are connected on two sides by the transverse filaments to the chromatin-anchoring lateral elements. Despite being found in most major eukaryotic taxa implying a deeply conserved evolutionary origin, several components of the complex exhibit unusually high rates of sequence turnover.

Fever in the Trauma Bay: A Marker for Greater Risk of Adverse Outcomes.

Previous work identified a sub-group of trauma patients at risk for bacteremia who presented with signs of infection, including fever. A majority were older adult falls who had early onset bacteremia. Fever in the trauma bay is associated with a greater risk of adverse outcomes and identifies patients who might benefit from early initiation of interventions for sepsis.

Colonic Derotation Revisited: The "Deloyers Procedure" for Long-Segment Hirschsprung Disease.

Long-segment Hirschsprung disease (HSCR) presents significant challenges in surgical management, often requiring extensive bowel mobilization and creative techniques to achieve tension-free anastomosis. Colonic derotation offers a viable solution for preserving bowel length and maintaining the ileocecal valve, which is crucial for postoperative bowel function. The procedure involves extensive colonic mobilization and strategic vascular divisions of the right and middle colic vessels while preserving the ileocolic and marginal arteries, followed by a 180° counterclockwise rotation of the colon around the ileocolic vascular axis.

Effects of Assisted Walking Exercise in Chronic Dependent Ambulatory Stroke Survivors: A Mini-Review.

Background: Assisted walking exercise programs are widely recommended in rehabilitation guidelines for stroke survivors. However, most evidence supporting these programs primarily focuses on ambulatory stroke survivors or those dependent ambulatory in acute and subacute stages. There is a notable gap in the application of walking exercise programs for chronic dependent ambulatory stroke survivors despite potential benefits in reducing sedentary behavior and improving rehabilitation outcomes.

Seamless Navigation of Bispecific Therapies: Optimizing Management and Outpatient Access With a Focus on Coordination.

Bispecific antibodies (BsAbs) have emerged as crucial therapeutic agents for patients with relapsed/refractory diffuse large B-cell lymphoma, multiple myeloma, and most recently, lung cancer. These therapies have demonstrated remarkable efficacy in clinical trials; however, multidisciplinary collaboration is essential to ensure optimal patient outcomes amid the operational complexities associated with BsAb therapy. As BsAbs are being prepared for broader adoption, clinicians and treatment centers must navigate operational challenges, including financial considerations, patient selection, caregiver involvement, and transitions of care.

Objective: To review the efficacy of iloperidone for mania associated with bipolar I disorder and discuss its safety profile (eg, QTc prolongation, orthostatic hypotension, and metabolic adverse effects).

Data Sources: Literature was identified using PubMed (1966-September 2024), OVID (1984-November 2024), and clinicaltrials.gov.

One is not like the other: health quality of life scores vary in neuromuscular EOS by diagnosis.

Purpose: The etiology of early-onset scoliosis (EOS) has been shown to significantly influence baseline parent-reported health-related quality of life (HrQOL). In combining these etiology groups, we obligatorily lump together many disparate diagnoses, particularly true in the neuromuscular (NM) cohort. We sought to evaluate the influence of underlying neuromuscular diagnosis on the HrQOL at 5 years following surgery for EOS.

The evolution of preferred male traits, female preference and the G matrix: "Toto, I've a feeling we're not in Kansas anymore".

Female preference exerts selection on male traits. How such preferences affect male traits, how female preferences change and the genetic correlation between male traits and female preference were examined by an experiment in which females were either mated to males they preferred (S lines) or to males chosen at random from the population (R lines). Female preference was predicted to increase the time spent calling by males.

Comparison of Clinical and Radiological Outcomes of Three-Column Lumbar Osteotomies with and without Interbody Cages for Adult Spinal Deformity.

Background Context: Correcting sagittal malalignment in adult spinal deformity (ASD) is a challenging task, often requiring complex surgical interventions like pedicle subtraction osteotomies (PSOs). Different types of three-column osteotomies (3COs), including Schwab 3, Schwab 4, Schwab 4 with interbody cages, and the "sandwich" technique, aim to optimize alignment and fusion outcomes. The role of interbody cages in enhancing fusion and segmental correction remains unclear.

CLIPA protein pairs function as cofactors for prophenoloxidase activation in Anopheles gambiae.

Insect prophenoloxidases (proPO) are activated during immune responses by a proPO activating protease (PAP) in the presence of a high molecular weight cofactor assembled from serine protease homologs (SPH) that lack proteolytic activity. PAPs and the SPHs have a similar architecture, with an amino-terminal clip domain and a carboxyl-terminal protease domain. The SPHs belong to CLIPA subfamily of SP-related proteins.

Behavioral health comorbidities in hospital outcomes post-lower extremity amputation in patients with type 1 and type 2 diabetes.

Peripheral artery disease leading to chronic limb threatening ischemia (CLTI) represents a significant concern for up to 11.0 % of patients with diabetes, often culminating in amputation of the affected limb. This retrospective cohort study explores frequency of comorbid behavioral health conditions (CBHCs) in patients with diabetes and hospital stay characteristics related to post-lower extremity amputation (LEA).

A Mutant Complement Factor H (W1183R) Enhances Proteolytic Cleavage of von Willebrand Factor by ADAMTS13 Under Shear.

Background: A loss-of-functional mutation (W1183R) in human complement factor H (CFH) is associated with complement-associated hemolytic uremic syndrome; mice carrying a similar mutation (W1206R) in CFH also develop thrombotic microangiopathy but its plasma von Willebrand factor (VWF) multimer sizes were dramatically reduced. The mechanism underlying such a dramatic change in plasma VWF multimer distribution in these mice is not fully understood.

Objective And Methods: To determine the VWF and CFH interaction and how CFH proteins affect VWF multimer distribution, we employed recombinant protein expression, purification, and various biochemical and biophysical tools.

Formation and crystalline structure of spherulites from pea and high amylose maize starches.

Starch spherulite is a unique form of resistant starch characterized by a spherical structure with crystalline lamellae that are radially oriented and may find applications in delivery of nutrients and bioactives to the lower gastrointestinal tract. Formation of starch spherulites generally requires heating to a high temperature followed by quenching and long crystallization time. The objectives of this study were to gain a deeper understanding of the factors influencing spherulite formation from pea starch (PS) and high-amylose maize starch (HAMS) and investigate if spherulites could be formed by a slow cooling rate and determine the crystalline structure and morphology of the spherulites formed.

State of the Art in Left Atrial Appendage Occlusion.

Left atrial appendage occlusion (LAAO) has become an important therapeutic target for stroke prevention in patients with nonvalvular atrial fibrillation. Over the past 2 decades, several advancements in LAAO devices (percutaneous and surgical) have been made for stroke prevention and arrhythmia therapy. However, there are several unanswered questions regarding optimal patient selection, the preferred LAAO approach and device, the management of periprocedural and postprocedural complications, including pericardial effusion, device-related thrombus, and device leaks.
