This systematic review aimed to determine the prevalence of lower back pain (LBP) in equestrian athletes (EAs) and identify associated risk factors. Following the PRISMA guidelines, observational studies published between 2004 and 2024 in English, Portuguese, Spanish, and German were included. The review identified relevant studies through the Web of Science, EBSCO, MEDLINE, and SCOPUS (last search performed on 30 October 2024), yielding 14 studies with a total of 4527 participants.

The purpose of the study was to identify potential differences between patients with right colon cancer and left colon cancer in epidemiological, clinical presentation, pathological, and surgical results in addition to the impact of the sidedness on disease-free survival (DFS) and overall survival (OS). Patients with a diagnosis of colon cancer stages I-IV between 2010 and 2020 were identified from a prospective database in a tertiary single center. Right and left-sided cancer were compared regarding epidemiological, clinical presentation, pathological, and surgical results.

Article Synopsis
  • The study focused on identifying key immune molecules for diagnosing S. stercoralis infections using serum samples tested with specific antigens (AgS and AgM).
  • Results from IgG-ELISA showed decent sensitivity (82.3 to 85.3%) and varying specificity (60.0 to 93.3%), but some cross-reactivity with other helminth infections was noted.
  • A specific 140 kDa protein from AgS demonstrated perfect sensitivity and specificity without cross-reactivity, indicating its potential for creating reliable immunodiagnostic tests for strongyloidiasis.

Dental development is a complex process influenced by genetic and environmental factors. Dental enamel, primarily composed of hydroxyapatite, is formed through complex cellular and biochemical mechanisms. Although this is a stable process, genetic, nutritional, and environmental factores can lead to developmental defects such as hypomineralization and hypoplasia.

Intestinal cell death is a defining feature of Crohn's disease (CD), a major form of inflammatory bowel disease. The focus on this aspect of enteric inflammation has mainly been on epithelial cells, while other cell types such as stromal and myeloid cells have received less attention. Hypothesising that decreased macrophage viability in an oxidative environment could be a contributing factor to the pathophysiology of CD, we found that monocyte-derived macrophages from individuals with active CD (but not those in clinical disease remission) have increased sensitivity to cell death induced by HO.
