BACKGROUND: There is conflicting evidence about what factors influence outcomes after total knee replacement (TKR). The objective is to identify baseline factors that differentiate patients who achieve both, minimal clinically important difference (MCID) and a patient acceptable symptom state (PASS) in pain and function, measured by WOMAC, after TKR from those who do not attain scores above the cutoff in either of these dimensions. METHODS: One-year prospective multicentre study...

Economic inequality is increasing both globally and in various countries around the world, and such inequality has been linked to worsening health, well-being, and social cohesion. A key predictor for whether people take action against inequality is the extent to which they perceive it as illegitimate. We investigate how two variables jointly predict the legitimization of inequality, namely the perceived magnitude of differences in economic outcomes and the way these differences are described. Two experiments (total N = 190) tested whether framing the same difference in outcomes as an advantaged group having more or as a disadvantaged group having less moderates whether higher inequality is perceived as less legitimate...

AIM: This study evaluated whether anethole attenuates the inflammatory response and joint damage in a model of adjuvant-induced arthritis (AIA) in rats. METHODS: The animals were treated with 62.5-, 125-, or 250-mg/kg anethole daily for 21 days after AIA and necropsied on days 14 and 21 to evaluate the number of serum and synovial leukocytes (total and differential), serum cytokines (IL-2, IL-6, IL-12, IL-17, and TNF-α), and nitric oxide concentrations. Morphologic changes in the cartilage and bone of the femorotibial articulation in both left paw and right paw were studied in hematoxylin/eosin and Sirius Red-hematoxylin sections...

BACKGROUND: Tumor-induced osteomalacia (TIO) may result in a better prognosis after complete resection of the causative neoplasm. However, tumors located proximal to the articular surface of the metaphysis remain largely uninvestigated. METHODS: A retrospective study of sixteen patients was undertaken to evaluate treatment of tumors with joint arthroplasty and tumor resection. The bone metabolism index, hip/knee joint function, arthroplasty complications and symptoms were followed up for at least 12 months in each patient...

OBJECTIVE: This study aims to investigate the effects of a quadriceps isometric contraction exercise method in the treatment of knee osteoarthritis (OA). METHODS: A total of 250 patients with a confirmed diagnosis of knee OA were enrolled. The patients were randomly divided into an exercise treatment test group (128 patients) and a traditional treatment control group (122 patients). Quadriceps isometric contraction exercise was used in the test group, and local physiotherapy and oral nonsteroidal anti-inflammatory drugs were used in the control group...

Within the last ten years of biomedical implants, the focus is increasingly on bioceramics, specifically on zirconia (ZrO2 ). Hence, we analyzed the impact of zirconia particles in comparison to titanium (cpTi) particles on mature human osteoclasts (OCs) as little is known about the direct effect of wear particles on mature OCs and their role in the osteolytic process during aseptic endoprosthesis loosening. Changes in cell morphology and functionality of OCs incubated with particles in different concentrations were investigated...

AIM: Osteoarthritis (OA) is a chronic disease and has become a major health problem in recent years. OA causes chronic pain and disability and can induce mental disorders such as stress perception, depression and suicidal ideation. We investigated the incidence of perceived stress, depressed mood and suicidal ideation in OA patients, using the 2010-2012 Korea National Health and Nutrition Examination Survey (KNHANES). METHOD: A total of 8271 participants were included (3580 male and 4691 female)...

Soil organic carbon (SOC) dynamics are regulated by the complex interplay of climatic, edaphic and biotic conditions. However, the interrelation of SOC and these drivers and their potential connection networks are rarely assessed quantitatively. Using observations of SOC dynamics with detailed soil properties from 90 field trials at 28 sites under different agroecosystems across the Australian cropping regions, we investigated the direct and indirect effects of climate, soil properties, carbon (C) inputs and soil C pools (a total of 17 variables) on SOC change rate (rC , Mg C ha(-1) yr(-1) )...

The SLC8A1 (solute carrier family 8, member 1) gene, encoding Na(+) /Ca(2+) exchanger, is essential in regulating calcium reabsorption and homeostasis. Calcium homeostasis plays a key role in cell proliferation and apoptosis. We hypothesized that polymorphisms in five calcium-regulating genes (SLC8A1, ATP2B1, CALB1, CALB2, and CABP1) interact with calcium intake in relation to the risk of colorectal neoplasia. A two-phase (discovery and replication) study was conducted within the Tennessee Colorectal Polyp Study, including a total of 1275 cases and 2811 controls...

Treatment in periprosthetic joint infection (PJI) remains challenging. The failure rate of two-stage revision and irrigation and debridement with component retention in PJI suggests that biofilm cells have a high tolerance to antibiotic chemotherapy. Previous work has demonstrated that biofilm cells have high antibiotic tolerance in vitro, but there is little clinical evidence to support these observations. The aim of this study was to determine if retrieved antibiotic spacers from two-stage revision total knee arthroplasty for PJI have evidence of remaining viable bacteria...

REVIEW
Robin Queen
Ankle osteoarthritis is a debilitating disease with approximately 50,000 new cases per year leading to skeletal deformity, severe and recurrent pain, cartilage breakdown, and gait dysfunction limiting patient mobility and well-being. Although many treatments (total ankle arthroplasty (TAA), ankle fusion (arthrodesis), and ankle distraction arthroplasty) relieve pain, it is not clear that these procedures significantly improve patient mobility. The goal of the research presented here is to summarize what is presently known about lower extremity gait mechanics and outcomes and to quantify the impact of ankle osteoarthritis and TAA have on these measures using an explicitly holistic and mechanistic approach...

Importance: Mammographic screening is impractical in most of the world where breast cancers are first identified based on clinical signs and symptoms. Clinical breast examination may improve early diagnosis directly by finding breast cancers at earlier stages or indirectly by heightening women's awareness of breast health concerns. Objective: To investigate factors that influence time to presentation and stage at diagnosis among patients with breast cancer to determine whether history of previous clinical breast examination is associated with earlier presentation and/or earlier cancer stage at diagnosis...

The under-performance of supply chains presents a significant hindrance to disease control in developing countries. Stock-outs of essential medicines lead to treatment interruption which can force changes in patient drug regimens, drive drug resistance and increase mortality. This study is one of few to quantitatively evaluate the effectiveness of supply chain policies in reducing shortages and costs. This study develops a systems dynamics simulation model of the downstream supply chain for amikacin, a second-line tuberculosis drug using 10 years of South African data...

Stigma and mental health literacy affect access to and quality of treatment of major depression. Though mental health professionals seem better able to recognize major depression than the general public, they often hold similarly stigmatizing attitudes towards people suffering from the disorder. These attitudes are shaped jointly by the public stigma attached to mental illnesses as well as by the content and delivery of mental health professionals' undergraduate training. In line with this, the present study aimed to explore psychology students' ability to recognize major depression, their attitudes towards the disorder, and their views surrounding helpfulness of various interventions...

We propose a novel and efficient F(-) anion doping strategy for enhancing upconversion luminescence in upconversion nanophosphors. NaGd(MoO4)2:Yb(3+)/Er(3+) nanophosphors doped with different F(-) contents are synthesized hydrothermally. Rietveld refinement results obtained from X-ray diffraction data indicate that the Gd-O bond length decreases and the O-Gd-O bond angle varies with increasing F(-) content, resulting in augmented local crystal field strength and distorted local site symmetry of the dopant lanthanide sites...

Prosthetic joint infection is an unfortunate though well-recognized complication of total joint arthroplasty. An iliacus and/or iliopsoas muscle abscess is a rarely documented presentation of hip prosthetic joint infection. It is thought an unrecognized retroperitoneal nidus of infection can be a source of continual seeding of the prosthetic hip joint, prolonging attempts to eradicate infection despite aggressive debridement and explant attempts. The current study presents five cases demonstrating this clinical scenario, and discusses various treatment challenges...

Background: Differentiating between septic and aseptic joint prosthesis may be challenging, since no single test is able to confirm or rule out infection. The choice and interpretation of the panel of tests performed in any case often relies on empirical evaluation and poorly validated scores. The "Combined Diagnostic Tool (CDT)" App, a smartphone application for iOS, was developed to allow to automatically calculate the probability of having a of periprosthetic joint infection, on the basis of the relative sensitivity and specificity of the positive and negative diagnostic tests performed in any given patient...
