Background: Patients with colorectal cancer who have a raised systemic inflammatory response before surgery have been shown to have poorer long-term and short-term outcomes. The presence of an ongoing systemic inflammatory response in these patients may be due to impaired cortisol production. The aim of the present study was to examine the relationship between the perioperative systemic inflammatory response and endogenous cortisol production.
Methods: A prospective study was performed to incorporate the assessment of adrenocortical function using synthetic adrenocorticotrophic hormone, a short Synacthen test, as part of the preoperative assessment of patients undergoing resection for colorectal cancer.
Results: A total of 80 patients underwent short Synacthen testing. There were no significant associations between the baseline, 30 min, or change (both relative and absolute) in cortisol and age (all p > 0.10), sex (all p > 0.10), site (all p > 0.10), TNM stage (all p > 0.10), modified Glasgow prognostic score (all p > 0.10), NLR (all p > 0.10), white cell count (all p > 0.10) or postoperative C-reactive protein concentrations (all p > 0.10).
Conclusions: Impaired cortisol production was uncommon in patients with potentially curable colorectal cancer. The presence of a perioperative systemic inflammatory response was not significantly associated with impaired cortisol production.

The bovine uterus is susceptible to bacterial infections after calving, particularly from (), which often results in endometritis. Additionally, postpartum stress in cows can elevate cortisol levels in the body, inhibiting endometrial regeneration and reducing immune function, thereby further increasing the risk of infection. Selenium (Se) is a common feed additive in dairy farming, known for its anti-inflammatory and antioxidant effects.

We recently reported factors leading to different severity of ruminal pH drop in primiparous cows fed the same diet during transition and early lactation. The present study evaluates the effects of those severities on performance and several blood and balance parameters in the same 24 primiparous cows from 3 wk before calving until wk 10 in lactation. Dietary concentrate was increased for all cows from 32 before calving to 60% (DM basis) over the first wk in lactation, resulting in a diet with 40% non-fiber carbohydrates (NFC), and 14.

Prebiotic dietary fiber (PDF) may reduce feelings of stress or improve mood in healthy individuals. Yet gut intervention studies that focus on mood in daily life are lacking and few studies include extensive biological sample analyses to gain mechanistic insights. As part of a larger randomized placebo-controlled crossover study including healthy individuals, we explored the effects of 12 weeks of PDF (acacia gum and carrot powder) on everyday mood, as measured with ecological momentary assessment (EMA).

Accumulating studies have highlighted the links between stress-related networks and the HPA axis for emotion regulation and proved the mapping associations between altered structural and functional networks (called SC-FC coupling) in depression. However, the signatures of SC-FC coupling in subthreshold depression (StD) individuals and their relationships with HPA axis reactivity, as well as the predictive power of these combinations for discriminating StD, remain unclear. This cross-sectional study enrolled 160 adults, including 117 StD and 43 healthy controls (HC).

Although the most common cause of congenital adrenal hyperplasia (CAH) worldwide is 21-hydroxylase deficiency (21OHD), which accounts for more than 95% of cases, other rare causes of CAH such as 11 beta-hydroxylase deficiency (11βOHD), 3 beta-hydroxy steroid dehydrogenase (3β-HSD) deficiency, 17 hydroxylase deficiency and lipoid CAH may also be encountered in clinical practice. 11βOHD is the most common type of CAH after 21OHD, and CYP11B1 deficiency in adrenal steroidogenesis causes the inability to produce cortisol and aldosterone and the excessive production of adrenal androgens. Although the clinical and laboratory features are similar to 21OHD, findings of mineralocorticoid deficiency are not observed.
