A Systematic Review and Meta-Analysis of Surgical Approaches for Venous Thoracic Outlet Syndrome.

Introduction: There is currently no consensus on the optimal surgical approach for the treatment of venous thoracic outlet syndrome (vTOS). Surgical exposures for vTOS decompression include infraclavicular (IC), supraclavicular (SC), paraclavicular (PC), and transaxillary (AX) approaches. The purpose of this study is to provide a comprehensive review of the outcomes and major complications of these four surgical techniques.

Thermal stresses in porcelain veneered lithium disilicate and zirconia dental crowns: Comparative analysis using a validated viscoelastic finite element model.

This study aims to investigate the effects of material compatibility, variable cooling rates, and crown geometry on thermal stress development in porcelain-veneered lithium disilicate (PVLD) and porcelain-veneered zirconia (PVZ) dental crown systems, and subsequently anticipate parameters for their optimum performance. An anatomically correct 3D crown model was developed from STL files generated using 3D scans of the experimental crown sample. Next, the viscoelastic finite element model (VFEM) based on the 3D crown model was developed and validated for anatomically correct bilayer PVLD and PVZ crown systems.

Origins of T-cell-mediated autoimmunity in acquired aplastic anaemia.

Acquired aplastic anaemia (AA) is an autoimmune bone marrow failure disease resulting from a cytotoxic T-cell-mediated attack on haematopoietic stem and progenitor cells (HSPCs). Despite significant progress in understanding the T-cell repertoire alterations in AA, identifying specific pathogenic T cells in AA patients has remained elusive, primarily due to the unknown antigenic targets of the autoimmune attack. In this review, we will synthesize findings from several decades of research to critically evaluate the current knowledge on T-cell repertoires in AA.

Probing Surface Reactions on Multicomponent Glass Using Reflection-Absorption Infrared Spectroscopy.

The chemical reactivity of glass surfaces is often studied with elemental analysis techniques, and although such characterization methods provide insights on compositional changes from exposure to specific chemical conditions, molecule-specific chemical reactions are not determined unambiguously. This study demonstrates the use of reflection-absorption infrared spectroscopy (RAIRS) to detect molecular species on alkali-free boroaluminosilicate and alkali aluminosilicate glasses, using acetic acid vapor as a model reactant to probe reaction sites at the surface with or without pretreatment by aqueous solutions of varied pH. With the assistance of the theoretical calculation of spectral changes based on refractive indices of bulk materials, it was possible to identify the molecular species being removed and produced at the glass surface.

Return to Sport After Distal Biceps Tendon Repair: A Systematic Review.

Background: Ruptures of the distal biceps tendon (DBT) can affect the range of motion and strength of the elbow, raising concerns for patients seeking to restore normal function and engage in their regular activities, particularly returning to previous levels of sport participation.

Purpose: To characterize and assess the rate and timing of return to sport (RTS) after DBT repair.

Study Design: Systematic review; Level of evidence, 4.

Being in the minority boosts in-group love:Explanations and boundary conditions.

People appreciate members of their in-group, and they cooperate with them-tendencies we refer to as in-group love. Being a member of a minority (vs. majority) is a common experience that varies both between groups in a context and within a group between contexts, but how does it affect in-group love? Across six studies, we examined when and why .

Nursing Culture Within Higher Education: A Snapshot.

With little literature exploring the relationship between leadership styles within teams/departments and types of organizational culture in nursing education, we conducted an exploratory study to investigate leadership styles and culture types. An online survey using the Organizational Description Questionnaire was posted on two national nursing websites. Nearly 35 percent of participants in this pilot study (n = 43) identified their organization to be coasting, followed by high contrast (23%) and transformational (21%).

The Confrustion Constellation: A New Way of Looking at Confusion and Frustration.

There has been considerable research on confusion and frustration that has treated them as two unitary constructs, distinct from each other. In this article, we argue that there is instead a constellation of different types of confusion and frustration, with different antecedents, manifestations, and impacts, and that the commonalities between many types of confusion and frustration justify thinking of them as part of the same constellation of affect, distinct from other prominent affective categories. We discuss how these types of affect have been considered historically and in key models.

Chlorhexidine Compared with Povidone-Iodine in Intravitreal Injection: A Systematic Review and Meta-Analysis.

Povidone-iodine (PI) is the standard antiseptic for intravitreal injections (IVIs), while chlorhexidine (CHX) is a potential alternative. The efficacy of PI versus CHX in preventing endophthalmitis remains debated, with studies showing mixed results. To compare the effectiveness of using PI compared with CHX in IVI procedures regarding endophthalmitis rates, culture-positive endophthalmitis rates, and changes in visual acuity.

Assessing longitudinal prenatal knowledge and skills retention among community birth attendants enrolled in a novel school.

Objective: Guatemala has one of the highest rates of maternal mortality in Central America. A total of 60% of births in Guatemala are attended by traditional Mayan birth attendants, or comadronas. Their prevalence in these communities makes them a valuable resource to bridge home births with safe prenatal care.

Food availability has direct and delayed effects on structural growth and body reserves in garter snakes.

Phenotypic plasticity in body growth enables organisms to cope with unpredictable paucities in resource availability. Growth traits influence survival and reproductive success, and thereby, population persistence, and early-life resource availability may govern lifetime patterns in growth, reproductive success, and survival. The influence of early-life environment is decidedly consequential for indeterminately growing ectotherms, which rely on available resources and ambient temperatures to maximize fitness throughout life.

High Cirrhosis Surgical Volume Centers have Reduced Postoperative Mortality in Patients with Cirrhosis Undergoing Major Surgery.

Patients with cirrhosis have increased surgical risk and require care team expertise. We explored the association between center cirrhosis surgical volume and post-operative mortality in a large VA dataset. In this retrospective cohort study of 14,500 major surgeries in patients with cirrhosis, we found in adjusted analysis that high-volume centers (>16 surgeries in past year) had a 36% reduced hazard of post-operative mortality through 90 days versus low-volume centers (<9 surgeries in past year; hazard ratio 0.

Spontaneous Formation of Single-Crystalline Spherulites in a Chiral 2D Hybrid Perovskite.

In two-dimensional (2D) chiral metal-halide perovskites (MHPs), chiral organic spacers induce structural chirality and chiroptical properties in the metal-halide sublattice. This structural chirality enables reversible crystalline-glass phase transitions in (-NEA)PbBr, a prototypical chiral 2D MHP where NEA represents 1-(1-naphthyl)ethylammonium. Here, we investigate two distinct spherulite states of (-NEA)PbBr, exhibiting either radial-like or stripe-like banded patterns depending on the annealing conditions of the amorphous film.

Maternal milk cell components are uptaken by infant liver macrophages via extracellular vesicle mediated transport.

Milk is a multifaceted biofluid that is essential for infant nutrition and development, yet its cellular and bioactive components, particularly maternal milk cells, remain understudied. Early research on milk cells indicated that they cross the infant's intestinal barrier and accumulate within systemic organs. However, due to the absence of modern analytical techniques, these studies were limited in scope and mechanistic analysis.

Molecular Phosphide Complexes of Zirconium.

Molecular Zr phosphides are extremely rare, with no examples containing a one-coordinated and terminal triple-bonded phosphorus atom. We report here an isolable and relatively stable Zr phosphide complex, [(PN)Zr≡P{μ-Na(OEt)}] (), stemming from a cyclometalated Zr-hydride, [(PN)(PN')Zr(H)] (), and NaPH. Complex is prepared from two- or one-electron reductions of precursors [(PN)ZrCl] () or metastable Zr[(PN)ZrCl], respectively.

Immersive Videography of Ancient DNA Extraction for Community Engagement and Educational Initiatives by the Anson Street African Burial Ground Project.

Objective: Community engagement is an increasingly important component of ancient DNA (aDNA) research, especially when it involves archeological individuals connected to contemporary descendants or other invested communities. However, effectively explaining methods to non-specialist audiences can be challenging due to the intricacies of aDNA laboratory work. To overcome this challenge, the Anson Street African Burial Ground (ASABG) Project employed a GoPro camera to visually document the process of aDNA extraction for use in community engagement and education events.

Reprogramming of Fatty Acid Metabolism in Acute Leukemia.

Fatty acids are essential biomolecules that support several cellular processes, such as membrane structures, energy storage and production, as well as signal transduction. Accordingly, changes in fatty acid metabolism can have a significant impact on cell behavior, such as growth, survival, proliferation, differentiation, and motility. Therefore, it is not surprising that many aspects of fatty acid metabolism are frequently dysregulated in human cancer, including in highly aggressive blood cancers such as acute leukemia.
