Background: It has been shown that sex affects immunity, including cytokine production. Given that atherosclerosis is an inflammatory disease promoted by specific cytokines, such as interleukin (IL)-1β, IL-6, and tumor necrosis factor (TNF)-α, we aimed at evaluating whether sex could affect the levels of these proatherogenic cytokines in a group of healthy adults. In this analysis, we also included other cytokines and peptides that have been implicated in atherosclerosis development and progression. Methods: A total of 104 healthy adults were recruited; we measured circulating levels of IL-1β, IL-6, TNF-α, angiotensins and angiotensin-converting enzyme-2 (ACE2), as well as osteoprotegerin and receptor activator of nuclear factor κB ligand (RANKL). Results: IL-1β, IL-6, and TNF-α were significantly higher in men as compared to women. They were all associated with testosterone and the testosterone/estradiol ratio. They remained significantly associated with sex (but not with hormones) after being tested for potential confounders. Conclusions: Sex seems to influence the levels of proatherogenic cytokines. This is consistent not only with sex differences in vulnerability to infections but also with the higher cardiovascular risk exhibited by the male gender as compared to the female gender. Nevertheless, this association is only partly explained by hormone levels.
There are different cancers in the peri-ampullary region, including pancreatic ductal adenocarcinoma (PDAC), duodenum cancers (DCs), and ampullary adenocarcinoma (AAC). Here, significant morphological–molecular characterizations should be necessary for the distinction of primary tumours and classifications of their subtypes of cancers. The sub classification of AACs might include up to five different variants, according to different points of view, concerning the prevalence of the two more-cellular components found in the ampulla. In particular, regarding the AACs, the most important subtypes are represented by the intestinal (INT) and the pancreato-biliary (PB) ones. The subtyping of AACs is essential for diagnosis, and their identifications have been impacting clinical management responses to treatments and overall survival (os) after surgery. Pb is associated with a worse clinical outcome. Otherwise, the criteria, through which are possible to attribute its subtype classification, are not well established. A triage of immune markers represented by CK7, CK20, and CDX-2 seem to represent the best compromise in order to split the cohort of AAC patients in the INT and PB groups. The test of choice for the sub-classification of AACs is represented by the immuno-histochemical approach, in which its molecular classification acquires its diagnostic, predictive, and prognostic value for both the INT and PB patients.
Background and Aims: Hypovitaminosis D is involved in the development and progression of atherosclerosis, and it is more prevalent in women. The differential impact of hypovitaminosis D on the severity of coronary artery disease (CAD) between genders remains poorly understood. This study aims to address this literature gap. Methods: A total of 1484 consecutive patients with acute myocardial infarction (AMI) were enrolled in the study. Hypovitaminosis D was defined as vitamin D ≤ 20 ng/mL. CAD was defined as the presence of at least one coronary vessel stenosis > 50%, while severe CAD was defined as left main disease and/or three-vessel disease > 50%. Results: The mean age of the cohort was 66.3 (11.5) years, with a predominance of the male gender (71.8%). Vitamin D values were significantly lower in women than in men (15.7 [8.4–25.4] ng/mL vs. 17.9 [11–24.3] ng/mL, p = 0.01). A higher prevalence of severe CAD was observed in female patients with hypovitaminosis D compared to those without (33% vs. 19%, p < 0.01). This finding was not observed in men. Among women, hypovitaminosis D significantly increased the risk of severe CAD (OR: 1.85, p = 0.01), together with diabetes mellitus (DM) and older age, adjusted for GFR < 60 mL/min/1.73 m2, cholesterol and body mass index. Furthermore, women with both hypovitaminosis D and DM had more than three times the risk of severe CAD compared with women who lacked both (OR: 3.56, p = 0.02). Conclusions: In women, hypovitaminosis D increases the risk of severe CAD, and the co-existence of hypovitaminosis D and DM triples the incidence of severe CAD.
