Patterns of object play behaviour and its functional implications in free-flying common ravens.

Object play has been proposed to provide individuals with information about their environment, facilitating foraging skills and tool use. In species where object play co-occurs with locomotor or social play, it may have additional functional implications, such as facilitating the evaluation of peers or forming social bonds. For instance, ravens judge others' competitiveness via play caching and engage in social play by exchanging objects.

Grading of Knee Osteoarthritis Based on Kellgren-Lawrence Classification and Finding an Association Between Radiographic Features and Pain: A Cross-Sectional Study at a Tertiary Health Care Hospital.

: Osteoarthritis leads to painful joints, disability, restriction of ambulation, and reduces the person's ability to perform activities of daily living. Pain is one of the major symptoms of osteoarthritis. Some patients presented with severe pain while some with severe deformity.

Predictors of Device-Related Thrombus After Left Atrial Appendage Occlusion: TED-F Score.

Background: Left atrial appendage (LAA) occlusion (LAAO) is performed to prevent LAA thrombus in patients with atrial fibrillation (AF). The risk of device-related thrombus (DRT) on the atrial side of the LAAO device is approximately 4%. Identifying patients at high risk of DRT would enable closer surveillance and more-aggressive anticoagulation to prevent post-LAAO DRT-related stroke.

Invasive Sino-Orbital Aspergillosis and Tinea Corporis Co-Infection in a Returned Traveler from Flooded Sylhet, Bangladesh.

We report a case of co-infection with Aspergillus fumigatus causing invasive sino-orbital aspergillosis and Trichophyton interdigitale tinea corporis in a returned traveler from flooded Sylhet region, Bangladesh. Anthropogenic climate change may lead to increased extreme weather-associated fungal infections. Travel to a flooded area should be considered a risk factor for fungal infection.

A Comparative Study of Bone-Health and Associated Factors in Healthy Indian Adolescents and Young Women.

Introduction: Adolescence is a critical period for the accrual of bone mass. However, few studies have assessed the bone geometry in slum-dwelling girls/young women. We thus conducted this study: (1) to assess bone health in Indian adolescent girls and young women residing in slum vs nonslum (NS) areas and (2) to identify factors associated with poor bone health.
