Stroke associated with microvascular tumoral infiltration in a patient with metastatic breast cancer.

Leptomeningeal carcinomatosis is a form of advanced metastatic disease conferring poor prognosis, most commonly associated with melanoma, small cell lung cancer, and breast cancer. In rare cases it has been shown to be associated with stroke thought to be related to vasculopathy caused by tumoral infiltration of cerebral vasculature. We present a case of acute cerebellar infarction in a patient with metastatic breast cancer complicated by leptomeningeal carcinomatosis, admitted for worsening metastatic disease.

Should we consider microbiota-based interventions as a novel therapeutic strategy for schizophrenia? A systematic review and meta-analysis.

Schizophrenia is a chronic psychiatric disorder characterized by a variety of symptoms broadly categorized into positive, negative, and cognitive domains. Its etiology is multifactorial, involving a complex interplay of genetic, neurobiological, and environmental factors, and its neurobiology is associated with abnormalities in different neurotransmitter systems. Due to this multifactorial etiology and neurobiology, leading to a wide heterogeneity of symptoms and clinical presentations, current antipsychotic treatments face challenges, underscoring the need for novel therapeutic approaches.

Ethics of Procuring and Using Organs or Tissue from Infants and Newborns for Transplantation, Research, or Commercial Purposes: Protocol for a Bioethics Scoping Review.

Unlabelled: Since the inception of transplantation, it has been crucial to ensure that organ or tissue donations are made with valid informed consent to avoid concerns about coercion or exploitation. This issue is particularly challenging when it comes to infants and younger children, insofar as they are unable to provide consent. Despite their vulnerability, infants' organs and tissues are considered valuable for biomedical purposes due to their size and unique properties.

Polygenic risk scores for atrial fibrillation and heart failure and the risk of stroke and dementia.

Atrial fibrillation and heart failure have both been suggested to increase stroke and dementia risk. However, in observational studies, reversed causation and unmeasured confounding may occur. To mitigate these issues, this study aims to investigate if higher genetic risk for atrial fibrillation and heart failure increases dementia and stroke risk.

Estrogen receptors in mitochondrial metabolism: age-related changes and implications for pregnancy complications.

Estrogen hormones are primarily associated with their role as female sex hormones responsible for primary and secondary sexual development. Estrogen receptors are known to undergo age-dependent decreases due to age-related changes in hormone production. In the mitochondria, estrogen functions by reducing the production of reactive oxygen species in the electron transport chain, inhibiting apoptosis, and regulating mitochondrial DNA content.

Travoprost Intracameral Implant in Eyes with Glaucoma or Ocular Hypertension: Early Short-Term Real-World Outcomes.

Purpose: To assess real-world efficacy and safety of standalone travoprost intracameral implant (iDose TR) implantation by a US glaucoma surgeon in patients with open-angle glaucoma (OAG) or ocular hypertension (OHT).

Methods: This non-randomized, retrospective, unmasked, consecutive case series included all cases of standalone iDose TR implantation from a single US glaucoma surgeon since the product's approval by the US Food and Drug Administration (FDA) in December 2023. Patients were pseudophakic, had OAG or OHT, and had undergone prior SLT and/or bimatoprost intracameral implant injection (Durysta).

Successful Treatment of Severe Ectopic ACTH-Dependent Cushing Syndrome Complicated by Hypocalcemia With Osilodrostat.

Cushing syndrome due to ectopic adrenocorticotropic hormone (ACTH) secretion (EAS) is rare and may progress rapidly, making treatment very challenging. We report a 27-year-old woman with metastatic neuroendocrine tumor (NET) who presented with sudden onset and rapidly progressing fatigue, muscle weakness, and weight gain. Laboratory findings confirmed severe EAS with new onset hypocalcemia, hypokalemia, and hyperglycemia.

New-onset Type 1 Diabetes Mellitus Presenting as Bilateral Cataracts in a 15-year-old Girl.

Cataracts secondary to type 1 or type 2 diabetes are not uncommon in adults; however, they are a rare finding in pediatric patients with type 1 diabetes. A 15-year-old girl presented with progressively worsened bilateral vision for 6 months. Her vision rapidly deteriorated over the previous month, prompting further evaluation that found bilateral cataracts with haziness in all layers and swollen lenses.

Mesenchymal Stem Cell-Sourced Exosomes as Potentially Novel Remedies for Severe Dry Eye Disease.

Severe dry eye disease (DED) is an inflammatory condition characterized by a lack of sufficient moisture or lubrication on the surface of the eye, significantly impacting the quality of life and visual function. Since detrimental immune response is crucially responsible for the development and aggravation of DED, therapeutic agents which modulate phenotype and function of eye-infiltrated inflammatory immune cells could be used for the treatment of severe DED. Due to their potent immunomodulatory properties, mesenchymal stem cells (MSCs) represent potentially new remedies for the treatment of inflammatory eye diseases.

Impact of race-based calculations of eGFR on the management of muscle invasive bladder cancer.

Purpose: The estimated glomerular filtration rate (eGFR) has historically been calculated with a race-coefficient multiplier (RCM); however, the RCM has been broadly criticized as inaccurate and a potential contributor to exacerbating disparities. We evaluated the impact of the RCM on eGFR and examined the 30-day post-cystectomy complications in a muscle-invasive bladder cancer cohort.

Materials And Methods: We retrospectively analyzed patients diagnosed with MIBC who underwent cystectomy in the ACS NSQIP database from 2006 to 2020 using CPT and ICD codes.

Impact of cell plasticity on prostate tumor heterogeneity and therapeutic response.

Epithelial-mesenchymal transition (EMT) is a dynamic process of lineage plasticity in which epithelial cancer cells acquire mesenchymal traits, enabling them to metastasize to distant organs. This review explores the current understanding of how lineage plasticity and phenotypic reprogramming drive prostate cancer progression to lethal stages, contribute to therapeutic resistance, and highlight strategies to overcome the EMT phenotype within the prostate tumor microenvironment (TME). Emerging evidence reveals that prostate tumor cells can undergo lineage switching, adopting alternative growth pathways in response to anti-androgen therapies and taxane-based chemotherapy.
