Evaluation of the Bioaccessability of Ca, Fe, Mg and Mn in Ground Coffee Infusions by in vitro

The bioaccessibility of Ca, Mg, Mn and Fe in ground coffee brews was assessed through in vitro gastrointestinal digestion with stomach and intestinal juice solutions (pepsin, pancreatin and bile salts). Absorption of metals in the intestinal villi was simulated by ultrafiltration over a 3 kDa molecular weight cut-off semi-permeable membrane. Concentrations of Ca, Fe, Mg and Mn in coffee infusions and permeates of gastrointestinal incubates were measured by flame atomic absorption spectrometry. It was established that Mg, with a 62% contribution to the bioaccessible fraction, was the most bioaccessible. The bioaccessibilities of Ca (42%) and Fe (43%) were similar but individual results for both metals varied widely. The least bioaccessible metal was Mn, with an average contribution of 27%. Drinking one cup of coffee daily covers dietary reference intakes of Ca, Fe, Mg and Mn to a small degree (less than 3%)

An analysis of the meal pattern at the nutrient level in Polish women

BACKGROUND: Before the 1990's, access to a variety of foods in Eastern Europe was limited, which could have influenced the currently analyzed dietary behaviors pertaining to overweight and obesity development. The aim of this study was to describe the daily profile of meal patterns in Polish women aged 50-70 at the nutrient level. METHODS: The anthropometrical parameters of four-hundred and fifty Polish women aged 50-70 were assessed. Three 24-hour dietary recalls and validated questionnaires regarding socio-demographic-economic status and meal frequency were applied. Timing in food intake was considered as follow: 6:00-8:59 CET - breakfast, 9:00-11:59 CET - morning snacks, 12:00-14:59 CET - lunch, 15:00-17:59 CET - afternoon snacks, 18:00-21:00 CET - dinner. Statistical analyses were conducted using Tukey's multiple comparison tests and discriminant analysis. RESULTS: No statistically significant differences were found in socio-demographic-economic and anthropometrical characteristics between women categorized to differentiated meal frequency intakes. However, the subjects from the 5-meal-per-day group were characterized by higher anthropometrical parameters, the statistically lowest percentage of regularity in meal consumption and skipping meals related to shortest breaks between meals. At the nutrient level, potassium, niacin, vitamin E and vitamin D were selected in the discriminant analysis as the nutrients most strongly related to different dietary behaviors. CONCLUSIONS: Our findings did not provide sufficient evidence that diverse nutrient intake could lead to the development of a specific nutritional profile in Polish women

Home Environment in Early-Life and Lifestyle Factors Associated with Asthma and Allergic Diseases among Inner-City Children from the REPRO_PL Birth Cohort

Objective. We hypothesized that, in our REPRO_PL cohort, exposure to indoor allergens and lifestyle factors in early life are associated with risk of asthma, atopic dermatitis, and allergic rhinitis at ten years of age. Methods. We only examined children who had lived in the same house from birth. Children’s exposure to tobacco smoke was assessed based on cotinine levels in urine. House dust samples were collected. Results. Higher Fel d1 concentration in house dust was associated with significantly higher risk of developing asthma at age 10 years (95% CI,10.87 to 20.93; p < 0.001). Frequent house cleaning was associated with development of atopic dermatitis (odds ratio 0.61; 95% CI 0.37 to 0.99; p = 0.045). Clustering of exposure to HDM revealed two types of environment. Cluster 1, defined as lower HDM (dust), in contrast to Cluster 2, defined as higher HDM, was characterized by old-type windows, lower fungus and dampness levels, as well as more frequent house cleaning. Conclusion. Exposure to cat allergens and new-type buildings that limit air flow while increasing the condensation of steam on the windows and thereby stimulating the growth of fungi are risk factors for the development of asthma

Changing patterns of urologic emergency visits and admissions during the COVID-19 pandemic : a retrospective, multicenter, nationwide study

INTRODUCTION: We aimed to examine the change in the number and severity of visits to the emergency departments (EDs) and subsequent admissions for urgent urologic conditions in the early stage of the coronavirus disease 2019 (COVID-19) pandemic in Poland. MATERIAL AND METHODS: We evaluated data from 13 urologic centers in Poland and compared the number of visits to the EDs and subsequent admissions before and after the advent of COVID-19 in 2020, and before and after the escalating national restrictions. Furthermore, data on types of urologic complaints, crucial laboratory parameters, and post-admission procedures were analyzed. RESULTS: In total 1,696 and 2,187 urologic visits (22.45% decrease) and 387 and 439 urologic urgent admissions (11.85% decrease) were reported in given periods in 2020 and 2019, respectively. The year-over-year difference in daily mean visits was clear (36.1 vs. 46.5; p < 0.001). Declines were seen in all complaints but device malfunction. In 2020 daily mean visits and admissions decreased from 40.9 and 9.6 before lockdowns to 30.9 (p < 0.001) and 6.9 (p = 0.001) after severe restrictions, respectively. There was a trend towards more negative laboratory parameter profiles in 2020, with patients who visited the EDs after severe restrictions having twice as high median levels of C-reactive protein (15.39 vs. 7.84, p = 0.03). CONCLUSIONS: The observed declines in ED visits and admissions were apparent with the significant effect of national lockdowns. Our results indicate that some of the patients requiring urgent medical help did not appear at the ED or came later than they would have done before the pandemic, presenting with more severe complaints
