Porphyra haitanensis proteins (PHP) are natural proteins with various nutritional and biological values. This study was to analyze the composition, stability, and antioxidant activity of PHP before and after simulation gastrointestinal digestion (SGD). Caenorhabditis elegans was used as the model to investigate the functional activity and potential mechanisms of action of the PHP digestion products (PHPDP).

Article Synopsis
  • A 58-year-old immunocompetent male experienced disseminated histoplasmosis (DH) despite being outside of known endemic regions.
  • His atypical symptoms led to a delay in diagnosis, highlighting the challenge of identifying DH in such cases.
  • The review emphasizes the importance of including histoplasmosis in differential diagnoses for immunocompetent patients, even when they have potential exposures outside endemic areas.

Article Synopsis
  • Coccidioidomycosis is a fungal infection common in the southwestern U.S. that can affect the musculoskeletal system, particularly in serious cases, though lower extremity involvement is less frequently documented.
  • The study highlighted three cases from southern Arizona showcasing different manifestations of lower extremity osteoarticular coccidioidomycosis, each with distinct clinical challenges and treatment approaches.
  • Effective treatment typically involves surgical debridement and extended antifungal therapy, emphasizing the need for careful diagnosis as the symptoms often resemble non-infectious conditions.

We report the case of a 56-year-old female with a past medical history of multiple sclerosis on disease-modifying therapy of fingolimod who presented with disseminated infection, initially of the ankles bilaterally before progressing to the central nervous system. CNS coccidiomycosis has thus far not been associated with any pharmacological therapy for multiple sclerosis. Clinicians should have a high degree of suspicion for infection in immunosuppressed patients living in endemic areas.

We report the case of a 78-year-old man with a past medical history of non-Hodgkin's lymphoma s/p chemotherapy and Myasthenia Gravis on chronic mycophenolate mofetil (MMF), who presented with altered mental status and was found to have ring enhancing brain lesions. A brain biopsy revealed organisms consistent with . Cerebral toxoplasmosis has been rarely reported in patients with hematologic malignancies or in those receiving immunosuppressive agents.

: Aspiration of intervertebral disc space is often done to confirm the diagnosis of native vertebral osteomyelitis. A study has not been done examining the utility of cell counts and differentials of the aspirated fluid in diagnosing native vertebral osteomyelitis (NVO). : In this feasibility study, we prospectively enrolled patients with a suspected diagnosis of NVO referred to the Division of Neuroradiology for image-guided needle aspiration of the intervertebral disc.

We describe a case of left hand extensor tenosynovitis due to histoplasmosis in a patient with dermatomyositis on chronic immunosuppression. Treatment involved surgical debridement and antifungal therapy. The patient experienced paradoxical worsening of tenosynovial inflammation during de-augmentation of immunosuppression felt to be immune reconstitution inflammatory syndrome.

Cardiac metastasis from head and neck cancer is an extremely rare and devastating condition with an abysmal prognosis. Most of our knowledge about this condition is from case reports and series. We present a case of squamous cell carcinoma of the tonsils that was complicated by embolic stroke and critical limb ischemia that were found to be secondary to intracardiac metastasis.

: Fungal prosthetic joint infections (PJIs) are rare and often associated with poor outcome; however, risk factors are not well described. : This was a retrospective case control study among all patients with PJIs from 2006-2016 at two major academic centers. Each fungal PJI case was matched 1:1 with a bacterial PJI control by joint (hip, knee, shoulder) and year of diagnosis.

Background: Postoperative state is characterized by increased thrombotic risk by virtue of platelet activation. Whether aspirin ameliorates this risk in patients with established coronary artery disease undergoing cardiac or noncardiac surgery is unknown. We conducted a systematic review and meta-analysis to compare the risk of major adverse cardiac events (MACE) and the risk of bleeding in patients with early (3-5 or more days before surgery) vs.

Background: The American College of Cardiology guidelines recommend 3 months of anticoagulation after replacement of the aortic valve with a bioprosthesis. However, there remains great variability in the current clinical practice and conflicting results from clinical studies. To assist clinical decision making, we pooled the existing evidence to assess whether anticoagulation in the setting of a new bioprosthesis was associated with improved outcomes or greater risk of bleeding.

Background: Anticoagulation with vitamin K antagonists such as warfarin has historically been used for the long term management of patients with thromboembolic disease. However, these agents have a slow onset of action which requires bridging therapy with heparin and its analogues, which are available only in parenteral route. To overcome these limitations, new oral anticoagulants such as factor Xa inhibitors and direct thrombin inhibitors have been developed.

Background: Infection is a serious complication of left ventricular assist device (LVAD) therapy. Published data regarding LVAD-associated infections (LVADIs) are limited by single-center experiences and use of nonstandardized definitions.

Methods: We retrospectively reviewed 247 patients who underwent continuous-flow LVAD implantation from January 2005 to December 2011 at Mayo Clinic campuses in Minnesota, Arizona, and Florida.
