Concurrent exposure of estuarine organisms to man-made and natural stressors has become a common occurrence. Numerous interactions of multiple stressors causing synergistic or antagonistic effects have been described. However, limited information is available on combined effects of emerging pharmaceuticals and natural stressors. This study investigated the joint effects of the antidepressant sertraline and salinity on Carcinus maenas. To improve knowledge about interactive effects and potential vulnerability, experiments were performed with organisms from two estuaries with differing histories of exposure to environmental contamination. Biomarkers related to mode of action of sertraline were employed to assess effects of environmentally realistic concentrations of sertraline at two salinity levels. Synergism and antagonism were identified for biomarkers of cholinergic neurotransmission, energy production, anti-oxidant defences and oxidative damage. Different interactions were found for the two study sites highlighting the need to account for differences in tolerance of local ecological receptors in risk evaluations.

Efficacy of brain stimulation therapies across psychiatric, movement, and cognitive disorders: an umbrella review synthesizing meta-analyses of randomized controlled trials.
EClinicalMedicine

Department of Psychiatry, Chaohu Hospital of Anhui Medical University, Hefei, Anhui, China.
Background: Brain stimulation therapy (BST) has significant potential in treating psychiatric, movement, and cognitive disorders. Given the high prevalence of comorbidities among these disorders, we conducted an umbrella review to comprehensively assess the efficacy of BSTs in treating the core symptoms across these three categories of disorders.
Methods: We systematically searched for meta-analyses and network meta-analyses of randomized controlled trials with sham controls up to September 25, 2024, from databases including PubMed, PsycINFO, Embase, and the Cochrane Library.
Efficient harvesting of triplet excitons multiple fast TTA up-conversion and high-lying reverse intersystem crossing channels for efficient blue fluorescent organic light-emitting diodes.

The efficient harvesting of triplet excitons is key to realizing high efficiency blue fluorescent organic light-emitting diodes (OLEDs). Triplet-triplet annihilation (TTA) up-conversion is one of the effective triplet-harvesting strategies. However, during the TTA up-conversion process, a high current density is necessary due to the competitive non-radiative triplet losses.

Purpose: Speech-language pathologists (SLPs) are tasked with integrating the principles of evidence-based practice (EBP) to provide effective and efficient assessment and intervention services that best support clients and their families. As new research, technologies, and perspectives emerge, SLPs are required to adapt their clinical practices to meet these changes while maintaining high-quality evidence-based services. Through an illustrative case study, we aim to demonstrate the process of applying EBP principles - including research evidence, client and family perspectives, and clinical expertise - to a complexity-based speech sound intervention delivered via telepractice.

Objective: To explore the therapeutic effect of titanium locking plate combined with suture anchor (SA) repair in the treatment of proximal humeral fractures (PHF).
Methods: This retrospective study was conducted by analyzing the clinical data of 113 patients with PHF admitted to Wuhan Fourth Hospital from March 2021 to October 2023. Among them, 55 patients underwent open reduction and internal fixation (OR/IF) using titanium locking plate (OR/IF group), and 58 patients underwent surgery with titanium locking plate combined with SA (SA group).
Comparing patient outcomes following outpatient total joint arthroplasty in a hospital setting versus an ambulatory surgery center.

University of Louisville, Department of Orthopaedic Surgery, United States.
Background: Traditionally, total joint arthroplasty has been performed as an inpatient procedure, sometimes requiring a hospital stay of a few days. However, outpatient total joints have gained popularity in recent years. The purpose of this study is to compare patient outcomes following an outpatient total knee arthroplasty (TKA) or a total hip arthroplasty (THA) in a hospital setting versus an ambulatory surgical center.
