Nutritional consistency of macroalgae across a sea ice cover gradient along the Western Antarctic Peninsula.

Sea ice can profoundly influence photosynthetic organisms by altering subsurface irradiance, but it is susceptible to changes in the climate. The patterns and timing of sea ice cover can vary on a monthly to annual timescale in small sub-regions of the Western Antarctic Peninsula (WAP). During the latter part of the 20th century, sea ice coverage significantly decreased in the WAP, a trend that aligns with warming in this area.

Young, Empowered & strong (YES): a study protocol paper for a randomized controlled trial of an mHealth symptom monitoring and self-management intervention for adolescent and young adult (AYA) breast cancer survivors.

Role of Allogeneic Hematopoietic Stem Cell Transplantation for Philadelphia Chromosome-Positive B-Cell Acute Lymphoblastic Leukemia in the Contemporary Era.

The treatment of Philadelphia chromosome-positive B-cell acute lymphoblastic leukemia (Ph+ B-cell ALL) has seen substantial progress over the past two decades. The introduction of tyrosine kinase inhibitor (TKIs) has resulted in dramatic improvements in long-term survival. Allogeneic hematopoietic stem cell transplantation (allo-HSCT), with its curative potential, has always been an integral part of the treatment algorithm of Ph+ ALL.

Effect of Gut Dysbiosis on Onset of GI Cancers.

Dysbiosis in the gut microbiota plays a significant role in GI cancer development by influencing immune function and disrupting metabolic functions. Dysbiosis can drive carcinogenesis through pathways like immune dysregulation and the release of carcinogenic metabolites, and altered metabolism, genetic instability, and pro-inflammatory signalling, contributing to GI cancer initiation and progression. infection and genotoxins released from dysbiosis, lifestyle and dietary habits are other factors that contribute to GI cancer development.

Molecular Dynamics Insights into Peptide-Based Tetrodotoxin Delivery Nanostructures.

Tetrodotoxin (TTX), a potent Site-1 sodium channel blocker (S1SCB), offers highly effective local anesthetic properties with minimal addiction potential. To fully leverage TTX's capabilities as a local anesthetic, it is crucial to develop a drug delivery system that balances its systemic toxicity with its therapeutic efficacy. Recent studies have shown that peptide mixtures, derived from fragments of Site-1 sodium channel proteins and enhanced with hydrophobic tails (designated MP1 and MP2), can self-assemble into nanostructures that exhibit remarkable sustained-release capabilities for TTX.

Association and multimodal model of retinal and blood-based biomarkers for detection of preclinical Alzheimer's disease.

Background: The potential diagnostic value of plasma amyloidogenic beta residue 42/40 ratio (Aβ42/Aβ40 ratio), neurofilament light (NfL), tau phosphorylated at threonine-181 (p-tau181), and threonine-217 (p-tau217) has been extensively discussed in the literature. We have also previously described the association between retinal biomarkers and preclinical Alzheimer's disease (AD). The goal of this study was to evaluate the association, and a multimodal model of, retinal and plasma biomarkers for detection of preclinical AD.

The Impact of Blood Pressure Below Personalized Lower Cerebral Autoregulation Limit on Outcomes After Cardiac Surgery: A Retrospective Study.

Objective: The clinical importance of individualized blood pressure management in optimizing cerebral perfusion during cardiac surgery has been well established. However, consensus on blood pressure goals is lacking. The authors studied the associations between cerebral autoregulation metrics, hemodynamic parameters, and postoperative outcomes, and hypothesized that increased time of mean arterial pressure (MAP) below the lower limit of autoregulation (LLA) is associated with major morbidity and mortality (MMOM) incidence.

Treatment of rapid recurrence of severe steatosis with combined GLP-1 agonist and growth hormone therapy in a pediatric patient transplanted for metabolic dysfunction-associated steatohepatitis cirrhosis in the setting of hypopituitarism.

The association between hypopituitarism and metabolic dysfunction-associated steatotic liver disease (MASLD) is increasingly recognized, although data about therapies targeting recurrence post-transplant is limited. An 8-year-old with hypopituitarism-associated MASLD underwent a liver transplant due to rapid progression of metabolic dysfunction-associated steatohepatitis (MASH). Hepatosteatosis recurred within weeks.

We compared survival and respiratory hospitalisation outcomes following initiation of TNF-inhibitor or non-TNF inhibitor biological or targeted synthetic DMARDs for treatment of rheumatoid arthritis-associated ILD.

Methods: We did a retrospective, active-comparator, new-user, observational cohort study with propensity score matching following the target trial emulation framework using US Department of Veterans Affairs (VA) electronic and administrative health records.

Social and Legal Needs in Patients and Families With Cancer: Interaction With Patient-Level Financial Toxicity.

Adverse financial burden and its effect on patients resulting from the costs associated with cancer care, both direct and indirect, is known as financial toxicity. This review explores the interplay between financial toxicity and key social and legal needs in cancer care. Drawing from the WHO's framework and the ASCO's policy statement on social determinants of health, we propose a conceptual model that discusses five key needs-housing insecurity, food insecurity, transportation and access barriers, employment disruptions, and psychosocial needs-which interact with, and are affected by financial toxicity, and adversely influence patients' well-being and adherence to treatment.
