In most cases, a standard access via a medial parapatellar arthrotomy with a carefully performed release technique is sufficient for a good exposure of the knee joint in the revision situation. Crucial steps are targeted scar removal, sufficient soft tissue release and recreation of the shifting layers. Tuberosity osteotomy is an effective option for extended exposure at the distal joint region, facilitating a patella replacement to correct abnormalities in the patellofemoral joint. Extended exposure to the proximal joint is possible with the rectus snip and the VY plasty technique. Due to the rather poor results, a quadriceps turndown should be seen more historically and should no longer be used. In extreme cases, a femoral peel or an osteotomy of the medial epicondyle can help achieve the reconstruction of a joint. The latter techniques are reserved for selected cases and always require a linked implant.

Background: Although primary progressive aphasia (PPA) is considered a rarer form of dementia, individuals living with PPA are increasingly identified by healthcare professionals. Research investigating speech-language assessment and intervention in PPA has been conducted primarily in monolingual speakers and little is known about clinical decision-making of speech-language pathologists (SLPs) working with bilinguals with PPA.
Methods: A comprehensive survey containing questions regarding clinician confidence, prioritization, and ratings of basic competency for Volkmer, Cartwright, Ruggero et al.
Background: The early detection of neurologic damage at the microscopic level when the disease is subclinical would facilitate intervention preventing progression or potentially reversing the condition. The early determination of drug efficacy could shorten the length of drug studies, thereby reducing research costs. The eye is the only place in the body where an artery, vein, and nerve can be directly visualized The nerve fiber layer of the retina is an outgrowth of the brain.

This study investigated the survival of human rotavirus (HRV) on fresh beef, chicken, and lettuce stored at various temperatures, as well as the effect of UV-C exposure on HRV viability on these food surfaces. At 20 °C, the survival rate of three HRV strains (WA, 89-12C2, and DS-1) on beef, chicken, and lettuce decreased within 3 days, with the most significant reduction observed on beef. When stored at 4 °C, a significant reduction in HRV viability was observed by day 7, with the greatest decrease observed on beef, followed by chicken and lettuce.

Prior work suggests that prenatal maternal depression and anxiety associate with disturbed child sleep in infancy. The current study evaluated whether these same associations extend to children at 3 years of age, and if so, whether the timing of symptoms in pregnancy is relevant.

Background: Extended reality (XR) technologies are increasingly being used to reduce health and procedural anxieties. The global effectiveness of these interventions is uncertain, and there is a lack of understanding of how patient outcomes might vary between different contexts and modalities.
Objective: This research used panoramic meta-analysis to synthesize evidence across the diverse clinical contexts in which XR is used to address common outcomes of health and procedural anxiety.
