Article Abstract
Objectives: The role of sex hormones in the pathogenesis of allergic and inflammatory conditions such as rhinitis has been receiving increased attention, with evidence supporting an inflammation-modulating role of estrogen and progesterone in the nasal mucosa. However, the specific influence of hormonal contraceptives in rhinitis has been sparsely studied. As such, we sought to investigate the association of systemic hormonal contraceptives with both allergic (AR) and nonallergic rhinitis (NAR) using a national data set of adults in the United States.
Methods: This study was conducted using data from 46,205 female participants aged 20-40 in the Research Program. Rhinitis diagnoses, systemic hormonal contraceptive use, and covariate data were extracted for all participants. These variables were included in multivariable logistic regression models assessing the association of any systemic hormonal contraceptive use with rhinitis, both AR and NAR. Separate models were conducted to examine the association of progestin-only contraceptives (POCs) and estrogen-containing contraceptives (ECCs) on the odds of rhinitis. Adjusted odds ratios (OR) and 95% confidence intervals (CI) were calculated.
Results: Systemic hormonal contraceptives were associated with AR (OR: 1.32; 95% CI: 1.20-1.44) but not NAR (OR: 1.20; 95% CI: 0.90-1.56) after controlling for covariates. When analyzing POCs and ECCs separately, both were associated with AR compared to those not taking any systemic hormonal contraceptives (OR: 1.29; 95% CI: 1.12-1.48 for POC, OR: 1.35; 95% CI: 1.21-1.51 for ECC) but were not significantly associated with NAR (OR: 1.04; 95% CI: 0.66-1.57 for POC, OR: 1.33; 95% CI: 0.95-1.81 for ECC).
Conclusion: Systemic hormonal contraceptive use was independently associated with AR, with no significant difference between POCs and ECCs, while not being associated with NAR. Our findings may support a hormonal role in the pathogenesis of AR, but further research is needed to establish causation and understand the underlying mechanisms linking systemic hormonal contraceptive use to AR.

Nonexpressor of pathogenesis-related genes 1 (NPR1) is a master regulator of salicylic acid (SA)- facilitated plant hormone signaling and plays a crucial role in plant defense through the activation of systemic acquired resistance (SAR). Although like genes are associated with stress responses in a variety of plant species, no thorough genome-wide investigation of these genes has been undertaken in pearl millet (). This study discovered seven -like genes on four pearl millet chromosomes (Chr1, Chr2, Chr4, and Chr6), which exhibit close affinity to NPRs from other plants and have common gene structures, conserved motifs, and domains.

Dramatic drop in reproductive hormone, especially estrogen level, from pregnancy to postpartum period is known to contribute to postpartum depression (PPD), but the underlying mechanism and the role of the estrogen receptors (ERs) in this process were unclear. Here, we used an estrogen-withdrawal-induced PPD model following hormone simulated pregnancy (HSP) in female Sprague-Dawley rats to induce depressive-like behaviors. After estrogen withdrawal, we observe an up-regulation of astrocyte-specific potassium channel (Kir4.

Aims: Bariatric surgery (BS) reduces obesity-associated systemic inflammation leading to multiple cardiovascular (CV) and metabolic benefits. Here, we tested whether measuring vaso-inflammatory cytokines, gut hormones, and circulating extracellular vesicles (EV) provide vaso-inflammatory-metabolic signatures that better correlate to CV-metabolic outcomes after BS, compared to a standard clinical assessment including body weight (BW) loss and traditional CV risk factors.
Methods: In 111 patients with severe obesity, conventional clinical-biochemical parameters and non-conventional vaso-inflammatory-metabolic markers were analyzed at baseline, after 1- (T12) and 3-years (T36) post-BS and were associated to post-surgical BW loss and improvement of patients' CV-metabolic profile.

Inflammatory breast cancer (IBC) is a rare and aggressive breast cancer type, accounting for 5-7% of breast cancer-related deaths, and its bilateral involvement is exceedingly uncommon. We report a case of metachronous bilateral IBC in a 50-year-old premenopausal woman with Charcot-Marie-Tooth disease, offering novel insight into the diagnostic, therapeutic, and molecular challenges of this condition. The patient initially presented with acute right breast erythema, skin thickening, and , followed by contralateral breast involvement with similar symptoms.
