Background: Biological medications have played a significant role in maintenance therapy for Crohn's disease (CD), but some cases become refractory to these agents. Methotrexate (MTX) appears to be a cost-effective and readily available drug for enhancing the effectiveness of maintenance therapy when used in combination with anti-tumor necrosis factor (anti-TNF) therapy in such cases. However, its effectiveness is still to be established.

Article Synopsis
  • This study examined how patient-reported disease burden and health-related quality of life (HRQoL) affect the decision to switch from nonbiologic to biologic therapy in people with plaque psoriasis.
  • It included biologic-naive patients aged 18 and older who were using nonbiologic treatments and gathered data on their disease burden and quality of life when they entered the CorEvitas Psoriasis Registry from April 2015 to August 2022.
  • Results showed that a higher reported burden was linked to a greater likelihood of switching to biologic treatment, indicating that patient experiences significantly influence treatment decisions alongside clinical assessments.

Background: The International Psoriasis Council (IPC) updated the classification of psoriasis severity to guide clinical decision-making. According to IPC guidelines, patients are considered candidates for systemic therapy when body surface area (BSA) is >10%, when lesions affect special body areas (ie, face, palms, soles, genitals, scalp, or nails), or when topical therapy fails to control symptoms.

Objective: To evaluate patient candidacy for systemic therapy in real-world settings, according to disease severity criteria.

  • Minimally invasive spinal surgery techniques like oblique lateral lumbar interbody fusion (OLLIF) provide better outcomes but involve dual C-Arm imaging, which hasn't been fully studied for radiation exposure to surgeons.
  • A study measured radiation doses during 121 OLLIF surgeries over 12 months, finding an average exposure of 0.06 mSv per surgery, well below safety limits.
  • The results emphasize the need for protective measures and monitoring radiation exposure, potentially leading to new guidelines in surgical practice. Future research could explore larger surgeon cohorts and more complex procedures.

Appendiceal mucocele is a rare entity first described by Carl von Rokitansky, characterized by cystic dilatation of the appendiceal lumen due to obstruction, epithelial proliferation or inflammation and accumulation of mucoid material. The cause can be either neoplastic or non-neoplastic. Patients with appendiceal mucocele can be asymptomatic or present with right lower quadrant pain which may mimic acute appendicitis.

  • Premature ventricular contractions (PVCs) are common in individuals with left ventricular (LV) systolic dysfunction, yet their prevalence in the general population is not well understood.
  • A multicenter study evaluated the prevalence of frequent (PVCs >5%) and high burden (PVCs >10%) PVCs among patients monitored with ambulatory Holter monitors, analyzing demographics and left ventricle ejection fraction (LVEF).
  • Results showed that PVCs >5% and >10% were present in 4% and 5% of participants, respectively, with higher prevalence in older males, while females had a lower occurrence of PVCs despite similar rates when LVEF <50%.

  • - Cervical cancer is the third most common female cancer globally and while chemoradiotherapy can improve survival by 6%, it often leads to serious side effects that diminish quality of life due to bone marrow suppression from pelvic radiation.
  • - A study of 69 patients with advanced cervical cancer analyzed their blood cell counts and side effects during treatment, revealing that factors like BMI, age, and radiation dose were linked to significant drops in hemoglobin and other blood cell levels.
  • - Specific radiation doses and techniques were found to correlate with severe blood count reductions, with neutropenia linked to gastrointestinal issues and a notable drop in leukocyte levels occurring around day 35 of treatment with 3D conformal radiotherapy.

  • Ulcerative colitis (UC) is an inflammatory bowel disease that causes inflammation in the rectum and colon, with a rising prevalence especially in developed countries and a potential link to colorectal cancer (CRC).
  • The study analyzed data from 91 UC patients who underwent colectomy to identify risk factors for dysplasia, noting that older age was a significant risk factor but found no other strong associations.
  • The findings highlight the importance of age in assessing dysplasia risk for UC patients, suggesting that older patients may need more careful management and screening for CRC; more research is needed to confirm these results.

Metabolic disorders (MDs), including dyslipidemia, non-alcoholic fatty liver disease, diabetes mellitus, obesity and cardiovascular diseases are a significant threat to human health, despite the many therapies developed for their treatment. Different classes of bioactive compounds, such as polyphenols, flavonoids, alkaloids, and triterpenes have shown therapeutic potential in ameliorating various disorders. Most of these compounds present low bioavailability when administered orally, being rapidly metabolized in the digestive tract and liver which makes their metabolites less effective.

Ulcerative colitis (UC) is a chronic idiopathic inflammatory bowel disease (IBD) that progressively affects mucosa and submuccosa of the colon and rectum in a continual pattern. In comparison, Crohn disease (CD), the other type of IBD, is a chronic transmural inflammatory disorder that can involve any part of the gastrointestinal tract. MR enterography (MRE) has emerged as an important imaging modality for the diagnosis and detection of disease activity and complications in CD, with comparable results to those of endoscopy.
