A systematic review and meta-analysis on absolute eosinophil counts and the risk of asthma in preschool children with wheezing: An EAACI Task Force Report.

Preschool children with wheezing disorders pose diagnostic and therapeutic challenges and consume substantial healthcare resources. Peripheral eosinophil blood count (EBC) has been proposed as a potential indicator for future asthma development. This review by the European Academy of Allergy and Clinical Immunology (EAACI) Preschool Wheeze Task Force aimed to provide systematic evidence for the association between increased EBC and the risk of future asthma, as well as to identify potential cutoff values. In February 2023, a search of PubMed, EMBASE, and Cochrane Library databases was conducted to identify studies comparing EBCs in preschool children with wheezing who continued to wheeze later in life and those who did not. Included observational studies focused on children aged <6 years with a wheezing disorder, assessment of their EBCs, and subsequent asthma status. No language or publication date restrictions were applied. Among the initial 3394 studies screened, 10 were included in the final analysis, involving 1225 patients. The data from these studies demonstrated that high EBC in preschool children with wheezing is associated with future asthma development, with odds ratios of 1.90 (95% CI: 0.45-7.98, p = .38), 2.87 (95% CI: 1.38-5.95, p < .05), and 3.38 (95% CI: 1.72-6.64, p < .05) for cutoff values in the <300, 300-449, and ≥450 cells/µL ranges, respectively. Defining a specific cutoff point for an elevated EBC lacks consistency, but children with EBC >300 cells/µL are at increased risk of asthma. However, further research is needed due to the limitations of the included studies. Future investigations are necessary to fully elucidate the discussed association.

The Impact of the Endocrine and Immunological Function of Adipose Tissue on Reproduction in Women with Obesity.

Obesity, which leads to metabolic dysregulation and body function impairment, emerges as one of the pressing health challenges worldwide. Excessive body fat deposits comprise a dynamic and biologically active organ possessing its own endocrine function. One of the mechanisms underlying the pathophysiology of obesity is low-grade systemic inflammation mediated by pro-inflammatory factors such as free fatty acids, lipopolysaccharides, adipokines (including leptin, resistin and visfatin) and cytokines (TNF-α, IL-1ß, Il-6), which are secreted by adipose tissue. Together with obesity-induced insulin resistance and hyperandrogenism, the exacerbated immune response has a negative impact on the hypothalamic-pituitary-gonadal axis at all levels and directly affects reproduction. In women, it results in disrupted ovarian function, irregular menstrual cycles and anovulation, contributing to infertility. This review focuses on the abnormal intracellular communication, altered gene expression and signaling pathways activated in obesity, underscoring its multifactorial character and consequences at a molecular level. Extensive presentation of the complex interplay between adipokines, cytokines, immune cells and neurons may serve as a foundation for future studies in search of potential sites for more targeted treatment of reproductive disorders related to obesity.

The Most Common Side Effects, Concerns and Discontinuation Patterns of Oral Contraceptive Pills Among Polish Women: A Cross-Sectional Study.

Objective: Over the decade, variety and effectiveness of contraception methods have greatly improved, resulting in increased popularity of oral contraceptive pills (OCPs). However, hormonal contraception carries the risk of multiple side effects. The lack of sufficient knowledge often leads to the development of health concerns, which can affect patient's adherence. The aim of our research was to describe a side effect profile of OCPs and assess the most frequent concerns and discontinuation reasons in Polish women. The survey included questions regarding OCPs utilization patterns, side effects, health concerns and attitudes of the responders. Materials and methods: This cross-sectional study was based on a survey, which was distributed online and open from 29 April to 15 May 2022. The survey included questions regarding OCPs utilization patterns, side effects, health concerns and attitudes of the responders. Results: Out of 1699 respondents, the current OCPs intake was reported by two thirds of women and 22% had a history of using them in the past. Seventy-nine percent of all OCPs users experienced adverse effects while 9% reported having concerns about safety and potential adverse effects. Decreased libido and weight gain were the most significant reasons for ceasing hormonal contraception. Moreover, the most common concerns and the most unfavorable side effects varied in different age groups. The occurrence of anxiety depended on age and education. Conclusion: Healthcare professionals prescribing OCPs should provide their patients with comprehensive counseling. Understanding and addressing concerns of young women can improve their compliance and reduce the number of unintended pregnancies.
