Infiltrating Ductal Breast Carcinoma in a Male Patient With Associated BARD1 Mutation.

Male breast cancer is an uncommon diagnosis with limited research on management and prognosis due to its rarity. We discuss a case of a 55-year-old male with a non-contributory past medical history who presented with an enlarging palpable mass of his right breast tissue at the 10:00 position. The ultrasound of the right breast showed a 2.

The catheterized bladder environment induces dysregulation of macrophage polarization exacerbating bacterial UTI.

Urinary catheterization causes bladder damage, predisposing hosts to catheter-associated urinary tract infections (CAUTIs). CAUTI pathogenesis is mediated by bladder damage-induced inflammation, resulting in accumulation and deposition of the blood-clotting protein fibrinogen (Fg) and its matrix form fibrin, which are exploited by uropathogens as biofilm platforms to establish infection. Catheter-induced inflammation also results in robust immune cell recruitment, including macrophages (Mϕs).

Postpartum Pubic Symphysis Diastasis: A Case Report.

We present the case of a 25-year-old African American female patient (G1P0) with a past medical history of brain arteriovenous malformation repair, pneumonia, and a urinary tract infection who was admitted to the labor and delivery floor at 39 weeks for a spontaneous vaginal delivery of a 4.025 kg female baby. In the immediate postpartum (PP) period, the patient presented with severe pelvic pain and trouble ambulating.

Fibrinolytic-deficiencies predispose hosts to septicemia from a catheter-associated UTI.

Catheter-associated urinary tract infections (CAUTIs) are amongst the most common nosocomial infections worldwide and are difficult to treat partly due to development of multidrug-resistance from CAUTI-related pathogens. Importantly, CAUTI often leads to secondary bloodstream infections and death. A major challenge is to predict when patients will develop CAUTIs and which populations are at-risk for bloodstream infections.

Venous-plexus-associated lymphoid hubs support meningeal humoral immunity.

There is increasing interest in how immune cells in the meninges-the membranes that surround the brain and spinal cord-contribute to homeostasis and disease in the central nervous system. The outer layer of the meninges, the dura mater, has recently been described to contain both innate and adaptive immune cells, and functions as a site for B cell development. Here we identify organized lymphoid structures that protect fenestrated vasculature in the dura mater.

Antimicrobial peptide-conjugated phage-mimicking nanoparticles exhibit potent bactericidal action against in murine wound infection models.

is a causative agent for strep throat, impetigo, and more invasive diseases. The main reason for the treatment failure of streptococcal infections is increased antibiotic resistance. In recent years, infectious diseases caused by pyogenic streptococci resistant to multiple antibiotics have been rising with a significant impact on public health and the veterinary industry.

Exploring Novel Non-pharmacologic Approaches to Address Preoperative Anxiety and Postoperative Pain in Pediatric Patients Undergoing In-Patient Surgical Procedures: A Scoping Review.

The pediatric population is more prone to experiencing anxiety and fear before undergoing an inpatient surgical procedure than adults. Non-pharmaceutical interventions, such as music therapy and virtual reality programs, have shown significant promise in reducing the post-operative pain associated with pre-operative anxiety of patients and their caregivers. While there is evidence to support the use of non-pharmaceutical treatment in the mitigation of pre-operative anxiety, there are limited published reports of non-pharmacological interventions for pre-operative anxiety in children undergoing inpatient surgical procedures.

Synergistic roles of tristetraprolin family members in myeloid cells in the control of inflammation.

Members of the tristetraprolin (TTP) family of RNA-binding proteins can bind to and promote the decay of specific transcripts containing AU-rich motifs. ZFP36 (TTP) is best known for regulating pro-inflammatory cytokine expression in myeloid cells; however, its mammalian paralogues ZFP36L1 and ZFP36L2 have not been viewed as important in controlling inflammation. We knocked out these genes in myeloid cells in mice, singly and together.

Fibrinolytic-deficiencies predispose hosts to septicemia from a catheter-associated UTI.

Catheter-associated urinary tract infections (CAUTIs) are amongst the most common nosocomial infections worldwide and are difficult to treat due to multi-drug resistance development among the CAUTI-related pathogens. Importantly, CAUTI often leads to secondary bloodstream infections and death. A major challenge is to predict when patients will develop CAUTIs and which populations are at-risk for bloodstream infections.

This Commentary discusses Massachusetts' statutory provisions supporting cannabis research, advances in social equity driven by data, and critical policy issues, which invite questions without clear scientific answers.

A protocol for visualization of murine in situ neurovascular interfaces.

Mapping cranial vasculature and adjacent neurovascular interfaces in their entirety will enhance our understanding of central nervous system function in any physiologic state. We present a workflow to visualize in situ murine vasculature and surrounding cranial structures using terminal polymer casting of vessels, iterative sample processing and image acquisition, and automated image registration and processing. While this method does not obtain dynamic imaging due to mouse sacrifice, these studies can be performed before sacrifice and processed with other acquired images.

Background: TOS is a challenging condition where controversy remains in diagnosis and treatment, primarily given a lack of data exploring various treatment approaches and associated patient outcomes.

Methods: Patients who underwent unilateral, supraclavicular thoracic outlet decompression, or pectoralis minor tenotomy for neurogenic, venous, or arterial TOS were identified from a prospectively maintained database.

Toxicology Certification: The Need, the Value, and an Evolving Landscape.

Certification in toxicology remains a subject of interest to those in the field, as evidenced by the number of presentations at major meetings and publications in the past decade. In 2009, Brock and colleagues summarized the certifications available in the field of toxicology and provided an international perspective of the pros and cons of gaining certification. Though that article has been viewed thousands of times, the certification processes have evolved over the past decade.

Generation and characterization of a plasminogen-binding group A streptococcal M-protein/streptokinase-sensitive mouse line.

Background: Streptococcus pyogenes (GAS) is a human bacterial pathogen that generates various mild to severe diseases. Worldwide, there are approximately 700 million cases of GAS infections per year. In some strains of GAS, the surface-resident M-protein, plasminogen-binding group A streptococcal M-protein (PAM), binds directly to human host plasminogen (hPg), where it is activated to plasmin through a mechanism involving a Pg/bacterial streptokinase (SK) complex as well as endogenous activators.

Nonclinical Safety Assessment of Lipid Nanoparticle-and Emulsion-Based Self-Amplifying mRNA Vaccines in Rats.

Vaccines containing mRNA with the capacity to self-amplify represent an alternative to the mRNA vaccines that came to prominence during the COVID-19 pandemic. To gain further insights on the safety profile of self-amplifying mRNA- (SAM-) vaccines, this preclinical toxicology study in rats evaluated the effect of (i) the type of delivery system (lipid nanoparticle [LNP] vs cationic nano-emulsion [CNE]); (ii) antigen-encoding sequence (rabies glycoprotein G vs SARS-CoV-2 Spike); and (iii) RNA amplification. Further analyses also evaluated gene expression in peripheral blood after vaccination, and the biodistribution of vaccine RNA.

Streptolysin S targets the sodium-bicarbonate cotransporter NBCn1 to induce inflammation and cytotoxicity in human keratinocytes during Group A Streptococcal infection.

Group A (GAS, ) is a Gram-positive human pathogen that employs several secreted and surface-bound virulence factors to manipulate its environment, allowing it to cause a variety of disease outcomes. One such virulence factor is Streptolysin S (SLS), a ribosomally-produced peptide toxin that undergoes extensive post-translational modifications. The activity of SLS has been studied for over 100 years owing to its rapid and potent ability to lyse red blood cells, and the toxin has been shown to play a major role in GAS virulence .
