Shared Decision-Making in Total Hip and Knee Arthroplasty: Understanding Surgeon and Patient Perspectives Regarding When It Is Time for Surgery.

Background: Although total hip and total knee arthroplasty are highly successful operations, the decision of whether and when to undergo surgery is highly subjective and discretionary, and specific guidelines regarding readiness for surgery remain elusive. The nature of these decisions underscores the importance of shared decision-making, which is founded on the concept that patients substantially contribute to determining their own readiness for surgery. The OPTION survey was developed as a conversation aid to facilitate shared decision-making in the context of total joint arthroplasty.

Summer primary production of Arctic kelp communities is more affected by duration than magnitude of simulated marine heatwaves.

Fjord systems in the Norwegian Arctic are experiencing an increasing frequency and magnitude of marine heatwaves. These episodic heat stress events can have varying degrees of acute impacts on primary production and nutrient uptake of mixed kelp communities, as well as modifying the biogeochemical cycling in nearshore systems where vast areas of kelp create structural habitat. To assess the impact of future marine heatwaves on kelp communities, we conducted a 23 day mesocosm experiment exposing mixed kelp communities to warming and heatwave scenarios projected for the year 2100.

Acute colonic pseudo-obstruction in polytrauma patients.

Background: Acute colonic pseudo-obstruction (ACPO) is characterized by severe colonic distension without mechanical obstruction. It has an uncertain pathogenesis and poses diagnostic challenges. This study aimed to explore risk factors and clinical outcomes of ACPO in polytrauma patients and contribute information to the limited literature on this condition.

Productivity of mixed kelp communities in an Arctic fjord exhibit tolerance to a future climate.

Arctic fjords are considered to be one of the ecosystems changing most rapidly in response to climate change. In the Svalbard archipelago, fjords are experiencing a shift in environmental conditions due to the Atlantification of Arctic waters and the retreat of sea-terminating glaciers. These environmental changes are predicted to facilitate expansion of large, brown macroalgae, into new ice-free regions.

Liking Predicts Judgments of Authenticity in Real-Time Interactions More Robustly Than Personality States or Affect.

We conducted three studies involving small group interactions ( = 622) that examined whether Big Five personality states, affect, and/or liking predict judgments of others' authenticity. Study 1 ( = 119) revealed that neither -rated personality states nor affect predicted other-rated authenticity. Instead, other-rated liking was the only predictor of other-rated authenticity.

Experiencing Pain Invalidation is Associated with Under-Reporting of Pain: A Social Psychological Perspective on Acute Pain Communication.

Pain invalidation involves the dismissal or lack of understanding of another's pain, undermining their subjective experience. Frequent exposure to invalidation negatively impacts mental and physical health as well as pain-related behaviors, potentially leading people to conceal their pain from others in the future and/or withdraw from potential sources of support. It is therefore possible that experiencing pain invalidation may also impact pain-reporting behavior in clinical settings.

Unlocking Translational Potential: Conditionally Reprogrammed Cells in Advancing Breast Cancer Research.

Preclinical in vitro models play an important role in studying cancer cell biology and facilitating translational research, especially in the identification of drug targets and drug discovery studies. This is particularly relevant in breast cancer, where the global burden of disease is quite high based on prevalence and a relatively high rate of lethality. Predictive tools to select patients who will be responsive to invasive or morbid therapies (radiotherapy, chemotherapy, immunotherapy, and/or surgery) are relatively lacking.

Resilience and well-being among persons with spinal cord injury/disorders.

Purpose: We examined positive behavioral resources and characteristics that might distinguish resilient personality prototypes among persons with chronic spinal cord injury/disorder (SCID). Positive psychology variables with clear linkages to existing psychological interventions were examined as potential mediators of the resilience-well-being relationship. Research Method and Design: A cross-sectional, self-report study was conducted.

Propagated Circulating Tumor Cells Uncover the Potential Role of NFκB, EMT, and TGFβ Signaling Pathways and in Metastasis.

Circulating tumor cells (CTCs), a population of cancer cells that represent the seeds of metastatic nodules, are a promising model system for studying metastasis. However, the expansion of patient-derived CTCs ex vivo is challenging and dependent on the collection of high numbers of CTCs, which are ultra-rare. Here we report the development of a combined CTC and cultured CTC-derived xenograft (CDX) platform for expanding and studying patient-derived CTCs from metastatic colon, lung, and pancreatic cancers.

Overexpression of the telomerase holoenzyme induces EMT and tumorigenesis of HPV-immortalized keratinocytes.

Cervical cancer is the most frequent malignancy of the female genital tract and is associated with persistent infection of the uterine cervix with high-risk human papillomaviruses (HPV). The two HPV oncoproteins, E6 and E7, cooperatively immortalize cervical cells and are essential but insufficient for inducing tumorigenicity. During the progression of HPV-associated cervical dysplasia to carcinoma, the cellular telomerase reverse transcriptase (TERT) gene is activated and the TERC gene amplified.

A moodle course to substitute resuscitation teaching in a medical curriculum during the COVID-19 pandemic: A prospective pilot study.

Background: Face-to-face medical education was restricted during the COVID-19 pandemic, leading to alternative teaching methods. Moodle (Modular Object-Oriented Dynamic Learning Environment) - an online course format - has not yet been sufficiently evaluated for its feasibility and effectiveness in teaching cardiopulmonary resuscitation.

Methods: Medical students in the eighth semester took part in a Moodle course teaching basic life support, the ABCDE-approach, airway management, and advanced life support.

Authentic for Thee But Not for Me: Perceived Authenticity in Self-Control Conflicts.

Is self-control authentic? Across several hypothetical scenarios, participants perceived impulsive actions as more authentic for others (Study 1a) but self-control as more authentic for themselves (Study 1b). Study 2 partially replicated this asymmetry. Study 3 accounted for behavior positivity because self-control was typically the more positive action in the previous studies.

Injury patterns, management and outcomes of retroperitoneal haemorrhage caused by lower intercostal arterial bleeding at a level-1 trauma centre: A 10-year retrospective review.

Objective: Haemorrhagic shock is a life-threatening complication of trauma, but remains a preventable cause of death. Early recognition of retroperitoneal haemorrhage (RPH) is crucial in preventing deleterious outcomes including mortality. Injury to the 9-11th intercostal arteries (i.

The injury patterns, management and outcomes of retroperitoneal haemorrhage caused by lumbar arterial bleeding at a Level-1 Trauma Centre: A 10-year retrospective review.

Purpose: Haemorrhagic shock remains a leading preventable cause of death amongst trauma patients. Failure to identify retroperitoneal haemorrhage (RPH) can lead to irreversible haemorrhagic shock. The arteries of the middle retroperitoneal region (i.

Ten-year incidence and treatment outcomes of closed degloving injuries (Morel-Lavallee lesions) in a level 1 trauma centre.

Introduction: Morel-Lavallée lesions (MLL), also referred to as closed degloving injuries, result from traumatic shearing forces with separation of the subcutaneous fat from the underlying fascia. The aim of this study was to determine the incidence and treatment of MLLs at a level 1 trauma centre.

Methods: Single-centre retrospective cross-sectional study of consecutive patients with an imaging diagnosis of a Morel-Lavallee lesion from 1/1/2010-31/12/2019.

Authenticity, meaning in life, and life satisfaction: A multicomponent investigation of relationships at the trait and state levels.

Objective: The present study sought to examine: (1) how the components of authenticity (i.e., authentic living, self-alienation, accepting external influence) relate to one another at between- and within-person levels of analysis; (2) how the authenticity facets relate to meaning in life (i.

100 Years of Chromosome Research in Rye, L.

Although microscopy and genetics were still in their infancy, there are cytological results produced a hundred years ago that are still relevant today. Since the 1920s, rye has been a subject of chromosome research. It started by plotting its mitotic and meiotic chromosomes to determine genome size.

Identifying drivers of breast cancer metastasis in progressively invasive subpopulations of zebrafish-xenografted MDA-MB-231.

Cancer metastasis is the primary cause of the high mortality rate among human cancers. Efforts to identify therapeutic agents targeting cancer metastasis frequently fail to demonstrate efficacy in clinical trials despite strong preclinical evidence. Until recently, most preclinical studies used mouse models to evaluate anti-metastatic agents.

Two conserved amino acids differentiate the biology of high-risk and low-risk HPV E5 proteins.

The high-risk alpha human papillomaviruses (HPVs) are responsible for 99% of cervical cancers. While the biological functions of the HPV E6 and E7 oncoproteins are well-characterized, the function of E5 has remained elusive. Here, we examined gene expression changes induced by E5 proteins from high-risk HPV-16 and low-risk HPV-6b in multiple pools of primary human keratinocytes.

AIB1 is a novel target of the high-risk HPV E6 protein and a biomarker of cervical cancer progression.

The high-risk human papillomaviruses (HPV-16, -18) are critical etiologic agents in human malignancy, most importantly in cervical cancer. These oncogenic viruses encode the E6 and E7 proteins that are uniformly retained and expressed in cervical cancers and required for maintenance of the tumorigenic phenotype. The E6 and E7 proteins were first identified as targeting the p53 and pRB tumor suppressor pathways, respectively, in host cells, thereby leading to disruption of cell cycle controls.

True self-attributions shape judgments of blame in the context of addiction-relevant crime.

In three studies, we examined how attributing the criminal actions of a drug-addicted offender to their "true self" influences perceptions of their blameworthiness. Study 1 revealed that attributing a drug-addicted offender's crime (theft) to his true self positively predicted judgments of the offender's blameworthiness for the crime. Study 2 employed an experimental design and revealed that information connecting a crime (vs.
