The optimal procedure for isolated end-stage medial compartment knee osteoarthritis (OA) remains uncertain, with debate persisting between unicompartmental knee arthroplasty (UKA) and total knee arthroplasty (TKA). The aim of this narrative review is to evaluate current outcome measures in knee arthroplasty (KA) and explore how evolving patient populations and technological advancements may necessitate the use of different patient-reported outcome measures (PROMs) for evaluating UKA. While UKA offers potential advantages over TKA in early pain relief and functional outcomes, most randomised control trials using traditional PROMs have failed to show definitive superiority.

Genomics is an increasingly important part of biology research. However, educating undergraduates in genomics is not yet a standard part of life sciences curricula. We believe this is, in part, due to a lack of standard concepts for the teaching of genomics.

Oncolytic virotherapy has shown great promise in mediating targeted tumor destruction through tumor-selective replication and induction of anti-tumor immunity; however, obstacles remain for virus candidates to reach the clinic. These include avoiding neutralizing antibodies, preventing stimulation of the adaptive immune response during intravenous administration, and inducing sufficient apoptosis and immune activation so that the body's defense can work to eradicate systemic disease. We have developed a co-formulation of oncolytic viruses (OVs) with Imagent lipid-encapsulated, perfluorocarbon microbubbles (MBs) to protect the OVs from the innate and adaptive immune system.

Background: We sought to define whether and how hepatic ischemia/reperfusion (I/R) as manifested by perioperative aspartate aminotransferase (AST) and alanine aminotransaminase (ALT) levels impact long-term outcomes after curative-intent resection of hepatocellular carcinoma (HCC).

Patients And Methods: Intrasplenic injection of HCC cells was used to establish a murine model of HCC recurrence with versus without I/R injury. Patients who underwent curative resection for HCC were identified from a multi-institutional derivative cohort (DC) and separate external validation (VC) cohort.

Multidirectional shoulder instability represents an ongoing challenge for orthopaedic surgeons, and multiple techniques have been described to treat this condition. Posterior glenoid dysplasia is a known risk factor for posterior instability as well as persistent or recurrent instability following posterior stabilization procedures. Recurrent shoulder instability complicated by capsular insufficiency due to underlying soft tissue disorders or multiple prior failed surgical procedures poses a challenging surgical problem.

Background: To combat the high prevalence of physical inactivity among children, there is an urgent need to develop and implement real-world interventions and policies that promote physical activity (PA) and reduce sedentary behaviour (SB). To inform policy makers, the current body of evidence for children's PA/SB interventions needs to be translated.

Objectives: The current systematic review and meta-analysis aimed to identify modifiable determinants of device-measured PA and SB targeted in available intervention studies with randomized controlled trial (RCT) and controlled trial (CT) designs in children and early adolescents (5-12 years) and to quantify the effects of the interventions within their respective settings on the determinants of PA/SB and the outcomes PA and SB.

Shoulder and neck concerns are prevalent musculoskeletal issues prompting medical attention, often stemming from scapulothoracic disorders that can serve as both the cause and consequence of other shoulder abnormalities. Scapular dyskinesis, fractures, benign and malignant masses, and neuropathies are frequently overlooked yet can substantially affect shoulder pain and function, particularly in athletes. Scapulothoracic disorders may lead to and/or be worsened by common shoulder abnormalities including those of the rotator cuff, neighboring bursae, and the glenohumeral articulation and labrum.

Article Synopsis
  • Stiff person syndrome spectrum disorder (SPSD) is a rare autoimmune condition with estimated prevalence of 1-2 cases per million, marked by muscle stiffness and painful spasms; this study aims to clarify its incidence and prevalence using data from the University of Colorado Health system.
  • A total of 273 patients were identified with potential SPSD diagnosis codes, but only 59 were confirmed to have the disorder, leading to a prevalence estimate of 2.11 cases per 100,000 persons.
  • Different clinical diagnostic criteria were assessed, revealing varying estimated prevalence rates for SPSD, indicating inconsistencies in diagnosis and classification within the population studied.

In this review work, we outline a conceptual path that, starting from the numerical investigation of the transition between weak chaos and strong chaos in Hamiltonian systems with many degrees of freedom, comes to highlight how, at the basis of equilibrium phase transitions, there must be major changes in the topology of submanifolds of the phase space of Hamiltonian systems that describe systems that exhibit phase transitions. In fact, the numerical investigation of Hamiltonian flows of a large number of degrees of freedom that undergo a thermodynamic phase transition has revealed peculiar dynamical signatures detected through the energy dependence of the largest Lyapunov exponent, that is, of the degree of chaoticity of the dynamics at the phase transition point. The geometrization of Hamiltonian flows in terms of geodesic flows on suitably defined Riemannian manifolds, used to explain the origin of deterministic chaos, combined with the investigation of the dynamical counterpart of phase transitions unveils peculiar geometrical changes of the mechanical manifolds in correspondence to the peculiar dynamical changes at the phase transition point.

  • Socioeconomic status (SES) affects the well-being of people living with HIV (PWH), and using area-level SES indicators can help when individual data isn't available.
  • ZIP code-level SES indicators were found to relate to viral suppression rates, and racial disparities in viral suppression narrowed by 3%-4% when accounting for SES factors.
  • This study suggests that including ZIP code-based SES can enhance understanding of how social determinants and racial disparities impact health outcomes for PWH.

Venture capital (VC) firms fund biopharmaceutical research and development (R&D) while incurring substantial financial risk. VC firms seek to invest in clinical areas with the greatest potential for financial return. Using a combination of data for clinical trials and VC investment deals between January 2014 and March 2024, we found that approximately 75% of VC investments were allocated to clinical trials studying small-molecule drugs compared to biologics or gene therapies, without substantial changes over the study period.

Article Synopsis
  • A study assessed children under 18 with antibodies to myelin oligodendrocyte glycoprotein (MOG-Ab), focusing on those with encephalitis who didn’t fit the criteria for acute disseminated encephalitis (ADEM), comparing them to those with ADEM.
  • Out of 235 MOG-Ab positive patients, 33 had encephalitis and 74 had ADEM, with common symptoms including headache, seizures, and fever; 24% had a normal initial brain MRI.
  • Findings indicated that children with encephalitis were generally older, more often admitted to intensive care, and had a delayed start of steroid treatment, suggesting MOG-Ab testing is essential for suspected encephalitis

  • Cervical artery dissection (CeAD) is a leading cause of ischemic strokes in young adults, and this study explored the effects of intravenous thrombolysis (IVT) on patients with CeAD and stroke symptoms.
  • Analyzed data from the STOP-CAD study, it found that IVT significantly improved functional independence after 90 days in patients without increasing the risk of symptomatic intracranial hemorrhage.
  • The results suggest that IVT is a beneficial treatment for eligible patients with CeAD, aligning with current medical guidelines on its use.

Background: Stroke prevention with direct-acting oral anticoagulant agents in patients with atrial fibrillation confers a risk of bleeding and limits their use. Asundexian, an activated factor XI (XIa) inhibitor, is an oral anticoagulant that may prevent strokes with less bleeding.

Methods: In a phase 3, international, double-blind trial, we randomly assigned high-risk patients with atrial fibrillation in a 1:1 ratio to receive asundexian at a dose of 50 mg once daily or standard-dose apixaban.
