Single-Dose Versus Extended Antibiotic Prophylaxis in Primary Hip and Knee Arthroplasty: A Systematic Review and Meta-Analysis.

The optimal duration of antibiotic prophylaxis for patients undergoing primary hip or knee arthroplasty remains debated. We conducted a systematic review and meta-analysis to compare the outcomes of single-dose versus extended antibiotic prophylaxis. Studies assessing these strategies for periprosthetic joint infection (PJI), revision surgery, and superficial surgical site infections were selected from systematic searches in PubMed, Embase, and the Cochrane Library.

Shearless effective barriers to chaotic transport induced by even twin islands in nontwist systems.

For several decades now it has been known that systems with shearless invariant tori, nontwist Hamiltonian systems, possess barriers to chaotic transport. These barriers are resilient to breakage under perturbation and therefore regions where they occur are natural places to look for barriers to transport. Here we describe a kind of effective barrier that persists after the shearless torus is broken.

Induction of ectosome formation by binding of phospholipases D from Loxosceles venoms to endothelial cell surface: Mechanism of interaction.

Members of the phospholipase D (PLD) superfamily found in Loxosceles spider venoms are potent toxins with inflammatory and necrotizing activities. They degrade phospholipids in cell membranes, generating bioactive molecules that activate skin cells. These skin cells, in turn, activate leukocytes involved in dermonecrosis, characterized by aseptic coagulative necrosis.

Shrinking shrimp-shaped domains and multistability in the dissipative asymmetric kicked rotor map.

An interesting feature in dissipative nonlinear systems is the emergence of characteristic domains in parameter space that exhibit periodic temporal evolution, known as shrimp-shaped domains. We investigate the parameter space of the dissipative asymmetric kicked rotor map and show that, in the regime of strong dissipation, the shrimp-shaped domains repeat themselves as the nonlinearity parameter increases while maintaining the same period. We analyze the dependence of the length of each periodic domain with the nonlinearity parameter, revealing that it follows a power law with the same exponent regardless of the dissipation parameter.

Letter to the Editor.

The authors wish to acknowledge that the information on the Monet website⁹ has now changed (2024) to reflect that exposures longer than 3 seconds are required for larger restorations and that overlapping exposures should be used. The website now states that for preparation areas that are larger than 5mm in depth and 8mm in diameter, two overlapping spot cures of 3 seconds are recommended (Figure 2). The single 1 and 3x1- second exposure times used in the article are not recommended by the manufacturer and should now be considered 'off-label' use of the Monet.

Clinical Performance of 3D Printed Resin Composite Posterior Fixed Dental Prosthesis: A Permanent Solution?

Objectives: This clinical trial aimed to evaluate the clinical outcomes of 3D-printed resin composite posterior fixed dental prosthesis (FDP) restorations.

Hydrogen Peroxide in the Pulp Chamber and Color Change in Maxillary Anterior Teeth After In-Office Bleaching.

While the literature has noted variations in hydrogen peroxide (HP) permeability, and consequently, tooth sensitivity among different types of anterior teeth, there is a scarcity of research on this specific topic. This study evaluated HP permeability and color change (CC) in different groups of human maxillary anterior teeth (canines, lateral incisors, and central incisors) after in-office bleaching with HP at 35%. Thirty teeth maxillary anterior (n=10) were bleached with HP at 35% gel in one session of three 15-minutes applications.

Evaluation of preheating methods for bulk-fill thermoviscous composite in non-carious cervical lesions: A 24-month randomized controlled trial.

Objective: This 24-month, double-blind, split-mouth randomized equivalence clinical trial compared the clinical performance of a bulk-fill thermoviscous composite resin using two different preheating methods for the restoration of non-carious cervical lesions (NCCLs).

Materials And Methods: Stability of dental implants with two different types of surface treatments was compared utilizing resonance frequency analysis (RFA).

Bio-fertilizer applications from poultry slaughterhouses in subtropical agriculture - Interactions between soil structure and nitrate dynamics.

The No-till system and organic fertilization combined can be a potential strategy to avoid nutrient leaching, as the soil structure plays a crucial role in retaining them. In this study, we evaluated the influence of different rates of a bio-fertilizer made of industrial organic waste (IOW) from a poultry slaughterhouse on the percolation and stocks of nitrate in disturbed and undisturbed soil samples collected from a subtropical no-till field in southern Brazil. In an incubation experiment, we performed a percolation experiment using lysimeters and simulated rainfall for 180 days and evaluated the remaining soil nitrate stock after the incubation period.

Cold-driven strategies as pre-fermentative techniques on winemaking: A review.

As a pre-fermentative practice, cold may facilitate the extraction of grape compounds, resulting in differentiated wines. To explore the potential of these practices, extensive research has been conducted on scientific publications since 2004. There are four main ways to apply cold in pre-fermentative practices: ice wine production, berry freezing, cold maceration of grape must, and cryoconcentration of grape must.

The dark art of light curing in dentistry.

Objective: This study was designed to show that the commonly reported irradiance values that are quoted in most publications inadequately describe the light output from light curing units (LCUs).

Methods: The total spectral radiant power (mW) output from 12 contemporary LCUs was measured with a fiberoptic spectroradiometer and a calibrated integrating sphere. Five recordings were taken for each LCU and exposure mode.
