This article reviews evidence for performing various imaging studies in patients with total hip prostheses. Routine follow-up is generally performed with radiography. Radiographs are also usually the initial imaging modality for patients with symptoms related to the prosthesis.

Objectives: This study aimed to investigate the demographic differences amongst patients diagnosed with infective endocarditis (IE), predictors of adverse events, and the association between clinical decision-making and adverse health outcomes amongst patients with IE.

Design: A retrospective cross-sectional study was conducted using the New South Wales (NSW) Admitted Patient Data Collection (APDC) from the Centre for Health Record Linkage (CHeReL).

Participants: All patients (N=18,044) from 2001 to 2020 in New South Wales who received a diagnosis of IE using ICD-10-AM diagnostic code 133.

While some stakeholders presume that studying abroad distracts students from efficient pursuit of their programs of study, others regard education abroad as a high impact practice that fosters student engagement and hence college completion. The Consortium for Analysis of Student Success through International Education (CASSIE), compiled semester-by-semester records from 221,981 students across 35 institutions. Of those students, 30,549 had studied abroad.

Chronic foot pain is a frequent clinical complaint, which can significantly impact the quality of live in some individuals. These guidelines define best practices with regards to requisition of imaging studies based on specific clinical scenarios, which have been grouped into different variants. Each variant is accompanied by a brief description of the usefulness, advantages, and limitations of different imaging modalities.

Nontraumatic neck pain is a leading cause of disability, with nearly 50% of individuals experiencing ongoing or recurrent symptoms. Radiographs are appropriate as initial imaging for cervical or neck pain in the absence of "red flag" symptoms or if there are unchanging chronic symptoms; however, spondylotic changes are commonly identified and may result in both false-positive and false-negative findings. Noncontrast CT can be complementary to radiographs for evaluation of new or changing symptoms in the setting of prior cervical spine surgery or in the assessment of extent of ossification in the posterior longitudinal ligament.

Across three experiments, participants were provided with a list of racist behaviors that purportedly were enacted from a fellow student but in fact were based on the participants' own behaviors. People consistently evaluated themselves as less racist than this comparison other, even though this other's racist behaviors were identical to their own. Studies 2a and 2b demonstrate this effect is quite robust and even occurs under social pressure and social consensus conditions in which participants were free to express their racial biases.

Radiographs are indicated as the first imaging test in all patients with chronic wrist pain, regardless of the suspected diagnosis. When radiographs are normal or equivocal, advanced imaging with MRI (without or without intravenous contrast or following arthrography), CT (usually without contrast), and ultrasound each has a role in establishing a diagnosis. Furthermore, these examinations may contribute to staging disease, treatment planning, and prognostication, even when radiographs are diagnostic of a specific condition.

Chronic ankle pain is a common clinical problem whose cause is often elucidated by imaging. The ACR Appropriateness Criteria for chronic ankle pain define best practices of image ordering. Clinical scenarios are followed by the imaging choices and their appropriateness.

Objective This study tested the hypothesis that presolidified chitosan-blood implants are retained in subchondral bone channels perforated in critical-size sheep cartilage defects, and promote bone repair and hyaline-like cartilage resurfacing versus blood implant. Design Cartilage defects (10 × 10 mm) with 3 bone channels (1 drill, 2 Jamshidi biopsy, 2 mm diameter), and 6 small microfracture holes were created bilaterally in n = 11 sheep knee medial condyles. In one knee, 10 kDa chitosan-NaCl/blood implant (presolidified using recombinant factor VIIa or tissue factor), was inserted into each drill and Jamshidi hole.

For over 50 years, a debate has existed over the use of Native American sports mascots; however, few empirical studies on the topic exist. The present study examined if supraliminal exposure to Native American mascots results in the application of negative stereotypes toward Native American people. Results indicated that the effect of Native American mascots was moderated by people's racial attitudes toward Native people.

Background: Human flora are the most common cause of bacteremia in immunocompromised patients. Activities of daily living (ADL), including oral care and daily chlorhexidine gluconate bathing, can lower the risk of infection.

Methods: To address ADL compliance in our pediatric oncology and bone marrow transplant patients, we adopted the ADL 1-2-3 initiative: daily chlorhexidine gluconate bath and linen change, at least 2 activities per day, and oral care 3 times per day.

Objective: Delivery of chitosan to subchondral bone is a novel approach for augmented marrow stimulation. We evaluated the effect of 3 presolidified chitosan-blood implant formulations on osteochondral repair progression compared with untreated defects.

Design: In N = 5 adult sheep, six 2-mm diameter Jamshidi biopsy holes were created bilaterally in the medial femoral condyle and treated with presolidified chitosan-blood implant with fluorescent chitosan tracer (10 kDa, 40 kDa, or 150k Da chitosan, left knee) or left to bleed (untreated, right knee).

Arsenic is one of the most common heavy metal contaminants found in the environment, particularly in water. We examined the impact of perinatal exposure to relatively low levels of arsenic (50 parts per billion, ppb) on neuroendocrine markers associated with depression and depressive-like behaviors in affected adult C57BL/6J mouse offspring. Whereas most biomedical research on arsenic has focused on its carcinogenic potential, a few studies suggest that arsenic can adversely affect brain development and neural function.

Objective: To compare health-related quality of life in 50-year-old adults who were born at term (> or =37 to 42 weeks' gestation) with intrauterine growth restriction (IUGR; birth weight <10th centile) and a group born at term without IUGR (> or =10th centile).

Design: Case control study.

Setting: A large regional maternity hospital in Northern Ireland.

A 10-year-old Thoroughbred mare was presented with a 2.5-week history of headshaking. Based on a thorough physical examination, blood analysis, and a fine needle aspirate of an enlarged thyroid gland, a tentative diagnosis of seasonal idiopathic headshaking was made.
