Controlled Dynamic Microfluidic Culture of Murine, Bovine, and Human Embryos Improves Development: Proof-of-Concept Studies.

Classical preimplantation embryo culture is performed in static fluid environments. Whether a dynamic fluid environment, like the fallopian tube, is beneficial for embryo development remains to be determined across mammalian species. Objectives of these proof-of-concept studies were to determine if controllable dynamic microfluidic culture would enhance preimplantation murine, bovine, and human embryo development compared to static culture.

Cardiovascular-Liver-Metabolic Health: Recommendations in Screening, Diagnosis, and Management of Metabolic Dysfunction-Associated Steatotic Liver Disease in Cardiovascular Disease via Modified Delphi Approach.

There is a new awareness of the widespread nature of metabolic dysfunction-associated steatotic liver disease (MASLD) and its connection to cardiovascular disease (CVD). This has catalyzed collaboration between cardiologists, hepatologists, endocrinologists, and the wider multidisciplinary team to address the need for earlier identification of those with MASLD who are at increased risk for CVD. The overlap in the pathophysiologic processes and parallel prevalence of CVD, metabolic syndrome, and MASLD highlight the multisystem consequences of poor cardiovascular-liver-metabolic health.

Lentiviral Gene Therapy with CD34+ Hematopoietic Cells for Hemophilia A.

Background: Severe hemophilia A is managed with factor VIII replacement or hemostatic products that stop or prevent bleeding. Data on gene therapy with hematopoietic stem-cell (HSC)-based expression of factor VIII for the treatment of severe hemophilia A are lacking.

Methods: We conducted a single-center study involving five participants 22 to 41 years of age with severe hemophilia A without factor VIII inhibitors.

Printed Nanomaterials for All-in-One Integrated Flexible Wearables and Bioelectronics.

Recent advancements in printing technologies allow for fabricating various wearable sensors, circuits, and integrated electronics. However, most printing tools have limited ranges of handling ink viscosity, a short working distance, and a limited feature size for developing sophisticated electronics. Here, this paper introduces an all-in-one integrated wearable electronic system via multilayer, multinanomaterial printing.

Lipid nanoparticle-mediated mRNA delivery to CD34 cells in rhesus monkeys.

Transplantation of ex vivo engineered hematopoietic stem cells (HSCs) can lead to robust clinical responses but carries risks of adverse events from bone marrow mobilization, chemotherapy conditioning and other factors. HSCs have been modified in vivo using lipid nanoparticles (LNPs) decorated with targeting moieties, which increases manufacturing complexity. Here we screen 105 LNPs without targeting ligands for effective homing to the bone marrow in mouse.

Effects of Social Determinants of Health and Social Support on Surgical Outcomes Among Patients Undergoing Hysterectomy.

Objective: To describe composite 30-day postoperative complication rates among patients undergoing hysterectomy during the coronavirus disease 2019 (COVID-19) pandemic and to determine baseline and postoperative mental health symptoms, levels of social support, and socioeconomic status and their association with hysterectomy outcomes.

Methods: This multicenter prospective cohort study at eight centers across the United States enrolled patients who underwent minimally invasive hysterectomy for benign indications during the COVID-19 pandemic. Patients completed preoperative and postoperative surveys assessing mental health (PHQ-9 [Patient Health Questionnaire]), social support (MOS-SS [Medical Outcomes Study Social Support Survey]), and socioeconomic status (Hollingshead Index [Hollingshead Four Factor Index of Socioeconomic Status]).

Rapid and Robust Identification of Sepsis Using SeptiCyte RAPID in a Heterogeneous Patient Population.

SeptiCyte RAPID is a transcriptional host response assay that discriminates between sepsis and non-infectious systemic inflammation (SIRS) with a one-hour turnaround time. The overall performance of this test in a cohort of 419 patients has recently been described [Balk et al., J Clin Med 2024, 13, 1194].

Diagnosis of Vascular Anomalies in Patients with Skin of Color.

Vascular anomalies can be broadly classified as vascular tumors or vascular malformations, depending on the degree of endothelial involvement. These lesions can be subtle and challenging to diagnose in individuals with darker skin tones, which can lead to a delay in treatment. Improving diagnostic accuracy of these lesions may prevent progression and potential adverse outcomes when left untreated.

Recommendations for defining disturbed flow as laminar, transitional, or turbulent in assays of hemostasis and thrombosis: communication from the ISTH SSC Subcommittee on Biorheology.

Blood flow is vital to life, yet disturbed flow has been linked to atherosclerosis, thrombosis, and endothelial dysfunction. The commonly used hemodynamic descriptor "disturbed flow" found in disease and medical devices is not clearly defined in many studies. However, the specific flow regime-laminar, transitional, or turbulent-can have very different effects on hemostasis, thrombosis, and vascular health.

Smart filtering facepiece respirator with self-adaptive fit and wireless humidity monitoring.

The widespread emergence of airborne diseases has transformed our lifestyle, and respirators have become an essential part of daily life. Nevertheless, finding respirators that fit well can be challenging due to the variety of human facial sizes and shapes, potentially compromising protection. In addition, the current respirators do not inform the user of the air quality in case of continuous long-term use.

Systemic T-cell activation and IFN-γ activity in indeterminate severe hepatitis are reminiscent of hemophagocytic lymphohistiocytosis: Implications for T-cell- and IFN-γ-directed therapies.

Background: Severe hepatitis cases in children are increasingly recognized, but the exact etiology remains unknown in a significant proportion of patients. Cases of indeterminate severe hepatitis (iSH) may progress to indeterminate pediatric acute liver failure (iPALF), so understanding its immunobiology is critical to preventing disease progression. Hemophagocytic lymphohistiocytosis (HLH) is a systemic hyperinflammatory disorder associated with T-cell and macrophage activation with liver injury.

Stretchable and biodegradable self-healing conductors for multifunctional electronics.

As the regenerative mechanisms of biological organisms, self-healing provides useful functions for soft electronics or associated systems. However, there have been few examples of soft electronics where all components have self-healing properties while also ensuring compatibility between components to achieve multifunctional and resilient bio-integrated electronics. Here, we introduce a stretchable, biodegradable, self-healing conductor constructed by combination of two layers: (i) synthetic self-healing elastomer and (ii) self-healing conductive composite with additives.

Sound-seeking before and after hearing loss in mice.

How we move our bodies affects how we perceive sound. For instance, head movements help us to better localize the source of a sound and to compensate for asymmetric hearing loss. However, many auditory experiments are designed to restrict head and body movements.

All-in-one wearable drug efficacy assessment systems for bulbar muscle function using amyotrophic lateral sclerosis animal models.

Preclinical studies are crucial for developing amyotrophic lateral sclerosis drugs. Current FDA-approved drugs have been created by monitoring limb muscle function and histological analysis of amyotrophic lateral sclerosis model animals. Drug candidates for this disease have yet to be tested for bulbar-onset type due to the limitations of traditional preclinical tools: excessive animal use and discrete detection of disease progress.

Identification and Management of Ankyloglossia and Its Effect on Breastfeeding in Infants: Clinical Report.

Ankyloglossia refers to a congenitally tight lingual frenulum that limits the motion of the tongue. Whether the release of a tight lingual frenulum in neonates improves breastfeeding is not clear. Because many of the symptoms of ankyloglossia overlap those of other breastfeeding difficulties, a team partnership is necessary.
