Background: In our country, the prevalence of latex allergy in health personnel has rarely been studied. Objective: To determine the prevalence and associated factors to self-reported latex allergy in health care workers. Methods: A cross-sectional study was conducted among 1,292 health care workers of a second level hospital. All workers were included and they were required to answer a structured questionnaire aimed at identifying latex allergy, atopic personal and family history, exposure to latex gloves and surgical background. Odds ratio (OR) and 95 % confidence interval (95 % CI) were estimated using regression logistic to investigate factors associated to latex allergy. Results: The female to male ratio was 2.4:1. The men age 38.4 ± 11.6 years. The prevalence of latex allergy auto-reported was 9.7 %, with a confidence interval of 95 % (95 % CI) 8.1 %-11.3 %. There was no statistical difference by workplace (p = 0.508). Factors associated with latex allergy included female gender (OR = 1.68; 95 % CI: 1.03-2.73, p = 0.037), personal history of atopy (OR = 4.82;, p < 0.0001), family history of atopic dermatitis (OR = 4.33, 95 % CI: 1.20-4.41) and history of allergy to fruits (OR = 4.33; 95 % CI: 2.62-7.14, p < 0.0001). Conclusions: Up to 10 out to 100 health workers may have latex allergy. The main factors associated with latex allergy in this study were: being a female, personal or familiar atopy and allergy to fruits.

AbstractBackground: The prevalence of food sensitization in adults shows differences owing to geographic, regional and cultural circumstances. Objective: To identify the prevalence and factors associated with food sensitization in adults with allergic diseases. Methods: Cross-sectional study, where medical records of adult patients with any allergic disease and who tested positive to airborne allergens on at least one skin test were reviewed. Age, sex, underlying allergic disease and skin test result were recorded. Statistical analyses included food sensitization prevalence with the corresponding 95 % confidence intervals (CI), as well as a multivariate analysis to determine associated factors. Results: We included 258 patients with a mean of 36 years of age; 75 % were of the female sex. The most common underlying condition was allergic rhinitis (59 %). The prevalence of food sensitization was 37 % (95 % CI, 31.5-43.3) and it did not vary significantly according to sex or allergic disease in question. The most sensitizing food was soybeans (44.8 %), and associated factors were sensitization to cat dander (OR = 1.8; 95 % CI, 1.03-3.2) and 5 or more positive skin tests (OR = 4.3, 95 % CI 2.3-8.1). Conclusions: The prevalence of food sensitization in people with allergic disease was 40 %. Further studies are required to determine its prevalence in the general population.
Introduction Young women under 30 years with breast cancer (BC) are an emerging challenge. The purpose is to identify prognostic factors for survival in young women under 30 years of age with BC. Material and methods A retrospective cohort study was conducted among women younger than or equal to 40 years with BC and who were treated at the State Cancer Center during the period 2012–2017. Overall survival was assessed using the Kaplan–Meier method and the log-rank test. Univariate and multivariate analysis assessed survival predictors using Cox proportional hazards regression model. Results 282 young women were included. The >30-year-old subgroup showed a significant association with excess weight ( P = .002) compared to the <30-year-old group. The <30-year-old subgroup showed a poor overall survival (56.7%), as well as highly significant values in advanced clinical stages, metastatic nodules, metastasis, and neoadjuvant therapy ( P < .001). In Model 3 of the multivariate analysis, age <30 years (HR = 3.0; 95% CI 1.1 to 8.6), triple negative subtype (HR = 2.6; 95% CI 1.1 to 6.0), tumor size >5 cm HR = 2.3; 95% CI 1.03 to 5.1), and advanced clinical stages (HR = 6.6 95% CI 1.3 to 35.5) persisted as predictors. Conclusions Being very young (<30 years) is a predictor for limited survival compared to the age of 30–40 years, as well as the tumor covariates for a worse prognosis: triple negative subtype, advanced stages, positive lymph nodes, and distant metastases in liver.
