Background: The anterior oblique bundle of the medial ulnar collateral ligament (UCL) inserts on the anteroinferior aspect of the humeral medial epicondyle, while the flexor pronator mass (FPM) originates superficial and proximal to the UCL. With valgus stress, these distinct footprints may produce injury patterns that affect only focal areas of the medial epicondyle.
Hypothesis: The proximal UCL can act on the medial epicondyle either in isolation or in conjunction with the FPM to form partial avulsion fracture patterns within the pediatric medial epicondyle, and the predominant pattern involves only the proximal UCL footprint.

Chimeric antigen receptor (CAR) T-cell therapy is a potentially life-saving treatment for children with relapsed/refractory B-cell hematologic malignancies, and remains an important investigational therapy for other childhood cancers. Yet, access to this class of therapies remains suboptimal through both commercial use and clinical trials, especially in children, adolescents, and young adults. Using a series of case-based discussions, we outline guidance on real-world medical decision-making, and offer potential solutions to enhancing access to CAR T-cell therapy as a treatment modality.

Disease is a key driver of community and ecosystem structure, especially when it strikes foundation species. In the widespread marine foundation species eelgrass (Zostera marina), outbreaks of wasting disease have caused large-scale meadow collapse in the past, and the causative pathogen, Labyrinthula zosterae, is commonly found in meadows globally. Research to date has mainly focused on abiotic environmental drivers of seagrass wasting disease, but there is strong evidence from other systems that biotic interactions such as herbivory can facilitate plant diseases.

The subject of investigating causation in ecology has been widely discussed in recent years, especially by advocates of a structural causal model (SCM) approach. Some of these advocates have criticized the use of predictive models and model selection for drawing inferences about causation. We argue that the comparison of model-based predictions with observations is a key step in hypothetico-deductive (H-D) science and remains a valid approach for assessing causation.

Background: The Association for the Advancement of Blood and Biotherapies guidelines recommend the use of high-titer COVID-19 convalescent plasma (CCP) for patients with SARS-CoV-2 at high risk of disease progression, including those who are immunocompromised. We hypothesized that conventional plasma units have comparable neutralizing antibody levels to CCP.
Study Design And Methods: Conventional plasma and CCP units were obtained from blood suppliers.

Clinical research studies are becoming increasingly complex resulting in compounded work burden and longer study cycle times, each fueling runaway costs. The impact of protocol complexity often results in inadequate recruitment and insufficient sample sizes, which challenges validity and generalizability. Understanding the need to provide an alternative model to engage researchers and sponsors and bringing clinical research opportunities to the broader community, clinical research networks (CRN) have been proposed and initiated in the United States and other parts of the world.

Background: East African cichlid fishes have diversified in an explosive fashion, but the (epi)genetic basis of the phenotypic diversity of these fishes remains largely unknown. Although transposable elements (TEs) have been associated with phenotypic variation in cichlids, little is known about their transcriptional activity and epigenetic silencing. We set out to bridge this gap and to understand the interactions between TEs and their cichlid hosts.

Background: Congenital malaria remains a significant public health challenge in Nigeria, particularly in regions with high malaria endemicity. The increased vertical transmission of malaria is partly associated with the high susceptibility of women to malaria during pregnancy. This systematic review aimed to assess the prevalence, characteristics, and treatment outcomes of congenital malaria in Nigeria.

The etiology of inflammatory bowel disease (IBD) remains unclear, treatment options unsatisfactory and disease development difficult to predict for individual patients. Dysbiosis of the gastrointestinal microbiota and disruption of the biological clock have been implicated and studied as diagnostic and therapeutic targets. Here, we examine the relationship of IBD to biological clock and gut microbiota by using the IL-10 deficient () mouse model for microbiota-dependent spontaneous colitis in combination with altered (4 h/4 h) light/dark cycles to disrupt and time-restricted feeding (TRF) to restore circadian rhythmicity.

Dosage forms containing Ivermectin (IVER) and Praziquantel (PRAZ) are important combination drug products in animal health. Understanding the relationship between products with differing in vitro release characteristics and bioequivalence could facilitate generics. The goal of this study was to create granulations for each active ingredient, with similar release mechanisms, but substantially different in vitro release rates, and then compressing these granulations into tablets with differing release rates.

Current estimates of wetland contributions to the global methane budget carry high uncertainty, particularly in accurately predicting emissions from high methane-emitting wetlands. Microorganisms drive methane cycling, but little is known about their conservation across wetlands. To address this, we integrate 16S rRNA amplicon datasets, metagenomes, metatranscriptomes, and annual methane flux data across 9 wetlands, creating the Multi-Omics for Understanding Climate Change (MUCC) v2.

Polymeric nanoparticles (NPs) are promising tools used for immunomodulation and drug delivery in various disease contexts. The interaction between NP surfaces and plasma-resident biomolecules results in the formation of a biomolecular corona, which varies patient-to-patient and as a function of disease state. This study investigates how the progression of acute systemic inflammatory disease influences NP corona compositions and the corresponding effects on innate immune cell interactions, phenotypes, and cytokine responses.

Artificial intelligence (AI) is emerging as a valuable diagnostic tool in veterinary medicine, offering affordable and accessible tests that can match or even exceed the performance of medical professionals in similar tasks. Despite the promising outcomes of using AI systems (AIS) as highly accurate diagnostic tools, the field of quality assurance in AIS is still in its early stages. Our Part I manuscript focused on the development and technical validation of an AIS.
