Management of recurrent intussusception after Roux-en-Y gastric bypass.

While intussusception is a well described complication of Roux-en-Y gastric bypass (RYGB), cases of recurrent intussusception after lead point resection and reconstruction are described much less frequently. We present a case of a 28-year-old female with triple recurrent intussusception all of which were treated with surgical resection and reconstruction of her RYGB anastomoses. There is currently limited evidence to direct management in the setting of recurrent intussusception.

Open treatment of infected abdominal aortic aneurysm stemming from perineal infection.

Infected abdominal aortic aneurysms (AAAs) make up a small minority of AAAs yet are characterized by a high fatality rate, largely attributed to their increased risk of aneurysm rupture. This case details a rare presentation of a 56-year-old man that developed bacteremia secondary to a perineal abscess and subsequently experienced a 3 cm growth of his previously stable AAA over an 8 day period. This case underscores the importance of maintaining a heightened suspicion for infected aortic aneurysms in sick patients and highlights the critical role of surgical management in achieving source control.

Supraventricular Tachycardia (SVT) and Stroke: Should We Pump the Brakes on Cardioversion?

In the list of top 10 causes of death worldwide in 2019, stroke ranks number two, with a recent uptick in incidence involving younger adults. While common risk factors like tobacco use, hypertension, diabetes, and atrial fibrillation have been well studied, recent reports have also linked paroxysmal supraventricular tachycardia (PSVT) with strokes. This case highlights a rare presentation of a 25-year-old female who suffered an ischemic stroke shortly after undergoing chemical cardioversion for sustained SVT.

Nrf2-Mediated Dichotomy in the Vascular System: Mechanistic and Therapeutic Perspective.

Nuclear factor-erythroid 2-related factor 2 (Nrf2), a transcription factor, controls the expression of more than 1000 genes that can be clustered into different categories with distinct functions ranging from redox balance and metabolism to protein quality control in the cell. The biological consequence of Nrf2 activation can be either protective or detrimental in a context-dependent manner. In the cardiovascular system, most studies have focused on the protective properties of Nrf2, mainly as a key transcription factor of antioxidant defense.

PARP inhibitors chemopotentiate and synergize with cisplatin to inhibit bladder cancer cell survival and tumor growth.

Background: Management of bladder cancer (BLCA) has not changed significantly in the past few decades, with platinum agent chemotherapy being used in most cases. Chemotherapy reduces tumor recurrence after resection, but debilitating toxicities render a large percentage of patients ineligible. Recently approved immunotherapy can improve outcomes in only a third of metastatic BLCA patients.

Host nutrient milieu drives an essential role for aspartate biosynthesis during invasive infection.

The bacterial pathogen is capable of infecting a broad spectrum of host tissues, in part due to flexibility of metabolic programs. , like all organisms, requires essential biosynthetic intermediates to synthesize macromolecules. We therefore sought to determine the metabolic pathways contributing to synthesis of essential precursors during invasive infection.

MyD88 and IL-1R signaling drive antibacterial immunity and osteoclast-driven bone loss during Staphylococcus aureus osteomyelitis.

Staphylococcus aureus is able to infect virtually all organ systems and is a frequently isolated etiologic agent of osteomyelitis, a common and debilitating invasive infection of bone. Treatment of osteomyelitis requires invasive surgical procedures and prolonged antibiotic therapy, yet is frequently unsuccessful due to extensive pathogen-induced bone damage that can limit antibiotic penetration and immune cell influx to the infectious focus. We previously established that S.

Lumbar Sympathetic Plexus Block as a Treatment for Postamputation Pain: Methodology for a Randomized Controlled Trial.

Objective: We present a technical protocol for rigorous assessment of patient-reported outcomes and psychophysical testing relevant to lumbar sympathetic blocks for the treatment of postamputation pain (PAP). This description is intended to inform future prospective investigation.

Design: Series of four participants from a blinded randomized sham-controlled trial.

Repurposing the Nonsteroidal Anti-inflammatory Drug Diflunisal as an Osteoprotective, Antivirulence Therapy for Staphylococcus aureus Osteomyelitis.

Staphylococcus aureus osteomyelitis is a common and debilitating invasive infection of bone. Treatment of osteomyelitis is confounded by widespread antimicrobial resistance and the propensity of bacteria to trigger pathological changes in bone remodeling that limit antimicrobial penetration to the infectious focus. Adjunctive therapies that limit pathogen-induced bone destruction could therefore limit morbidity and enhance traditional antimicrobial therapies.
