AI Article Synopsis
- Some bad germs make toxins that hurt the lining of the colon (part of the digestive system).*
- Certain drugs called NSAIDs can make this problem worse, but scientists don’t fully understand how they do it.*
- The study found that NSAIDs and toxins work together to hurt the cells in the colon, which can make infections more serious.*
Article Abstract
damages the colonic mucosa through the action of two potent exotoxins. Factors shaping pathogenesis are incompletely understood but are likely due to the ecological factors in the gastrointestinal ecosystem, mucosal immune responses, and environmental factors. Little is known about the role of pharmaceutical drugs during infection (CDI), but recent studies have demonstrated that nonsteroidal anti-inflammatory drugs (NSAIDs) worsen CDI. The mechanism underlying this phenomenon remains unclear. Here, we show that NSAIDs exacerbate CDI by disrupting colonic epithelial cells (CECs) and sensitizing cells to toxin-mediated damage independent of their canonical role of inhibiting cyclooxygenase (COX) enzymes. Notably, we find that NSAIDs and toxins target the mitochondria of CECs and enhance toxin-mediated damage. Our results demonstrate that NSAIDs exacerbate CDI by synergizing with toxins to damage host cell mitochondria. Together, this work highlights a role for NSAIDs in exacerbating microbial infection in the colon.

Impact of potentially inappropriate medications on emergency ambulance admissions in geriatric patients after discharge.
Pharmazie
December 2024
Department of Hospital Pharmaceutics, School of Pharmacy, Showa University, Tokyo, Japan.
This study aimed to determine the risk of emergency admission by ambulance in patients taking potentially inappropriate medications (PIMs). We included 273,932 patients aged over 75 years of age admitted between January 1, 2019, and December 31, 2019, using the Japan Medical Data Center medical insurance database containing anonymized patient data. We excluded patients without a history of admission.

J Neurosurg Case Lessons

Department of Neurosurgery, Faculty of Medicine, Azad Tehran University of Medical Sciences, Tehran, Iran.
Background: Pedicle screw insertion in posterior spinal surgery can cause vascular injuries, including rare intercostal artery pseudoaneurysms, which are typically discovered incidentally during reimaging. Onyx embolization is an effective treatment for small artery pseudoaneurysms.
Observations: A 36-year-old man who had initially presented with back pain that remained unresponsive to nonsteroidal anti-inflammatory drugs was diagnosed with a T7-8 sarcomatous lesion confirmed by magnetic resonance imaging and biopsy.
Prophylactic Irradiation for the Prevention of Heterotopic Ossification After Foot Amputation: A Case Series.
J Am Podiatr Med Assoc
January 2025
‡Department of Plastic Surgery, Medstar Georgetown University Hospital, Washington, DC.
Background: The formation of heterotopic ossification (HO) is a common complication after transosseous partial foot amputation. Development of HO in weightbearing and/or superficial areas can lead to increased pressures, which increases the likelihood of wound formation and pain. Current treatment modalities for HO of the foot include mechanical off-loading and surgical resection; however, prophylactic measures such as nonsteroidal anti-inflammatory drugs, bisphosphonates, and other medical therapies have been attempted previously with mixed efficacy.

Variations of the ankle anatomy are infrequent and exist as supernumerary muscles and tendons. Often understudied and overlooked, their presence can cause many complications of the lower extremity. These muscles, although often asymptomatic, can cause great pain and complications such as tenosynovitis, tarsal tunnel syndrome, lateral ankle instability, and ankle pain when they impinge on the normal anatomy of the patient.

Perspect Clin Res
August 2024
Department of Nephrology, Seth GS Medical College and KEM Hospital, Mumbai, Maharashtra, India.
Background: Pharmacotherapy of chronic kidney disease (CKD) consists of prescribing myriad of drugs such as antihypertensives, antidiabetics, and phosphate binders to delay disease progression and control the comorbidities, resulting in inherent variability in prescriptions. In addition, tendency to self-medicate may further aggravate the condition. Hence, the present study was planned to assess self-medication practices and variability in prescription patterns in CKD patients.
