Aim: We evaluated the thickness of the adrenal cortex zones of female rats androgenized to mimic polycystic ovary syndrome.
Methods: Forty-four female virgin Wistar-Hannover rats were divided into two groups: controls (n = 17) and animals which received testosterone propionate on the 2nd day of life (n = 27). At 90 days of life, after confirmation of persistent estrus, the animals were sacrificed, and the adrenal cortex zones were evaluated. Student's t test and Levene's test were used in the statistical analysis (p < 0.05 considered significant).
Results: The adrenal glands of the androgenized rats were more voluminous and had a more intensely vascularized zona reticularis than the control animals. The mean thicknesses of zona glomerulosa and zona reticularis in the androgenized rats were 58.4 and 730.7 mum, respectively, significantly thicker than the values in the control group (45.0 and 328.3 mum, respectively).
Conclusion: Zona reticularis and zona glomerulosa of the androgenized female rats were significantly thicker than those of the control animals.

To investigate the characteristics of type 2 inflammation in patients with nocturnal asthma, and analyze the improvement of asthma symptoms after the use of inhaled corticosteroids (ICS) combined with different long-acting bronchodilators. Data of 231 asthma patients who first visited the Respiratory and Critical Care Medical Clinic of Nanfang Hospital of Southern Medical University from January 2020 to June 2023 and had positive bronchodilator tests (BDT), were retrospectively analyzed. These patients were divided into nocturnal asthma group and non-nocturnal asthma group based on the presence or absence of nocturnal symptoms.

Objective: To assess the effectiveness of a potent topical corticosteroid (TCS) as an initial treatment in primary care for children with moderate flare-ups of atopic dermatitis (AD), compared to starting on a mild TCS.
Design: An observational prospective cohort study with an embedded pragmatic multicentre open-label randomised controlled trial.
Setting: A total of 53 general practices in the southwest of the Netherlands took part in the study.
Comparative analysis of real-world data on the efficacy and safety of and adherence to ICS/LABA combinations in asthma management.

Background: Choosing effective devices (inhaled corticosteroid [ICS]-long-acting β2 agonist [LABA] combination inhalers) as maintenance treatment is critical for managing patients with asthma. We aimed to compare ICS/LABA combination efficacy, safety, and adherence across inhaler types and components in patients newly diagnosed with asthma.
Methods: Utilizing South Korea's National Health Insurance Service data, we conducted a population-based cohort study involving patients aged 18-80 years, newly diagnosed with asthma who received ICS/LABA combination therapy between January 2016 and December 2020.
The immune-inflammatory responses on the hypothalamic-pituitary-adrenal axis and the neurovascular unit in perioperative neurocognitive disorder.

Perioperative neurocognitive disorders (PNDs) refer to a wide spectrum of cognitive impairment persisting days to even after a year postoperative with significant morbidity and mortality. However, despite much efforts involving perioperative managements, PNDs are still prevalent with no standard preventative and therapeutic strategy. To overcome PNDs, a better understanding of pathophysiology of PNDs is crucial and a large number of studies have proven that immune-inflammatory responses from surgical stress are involved in the abnormal activation of the hypothalamic-pituitary-adrenal (HPA) axis and destabilization of neurovascular unit (NVU) that lead to PNDs.
