Lifestyle change-related stress, sensitive skin, discontinuation of oral contraceptives and using full-coverage foundations increase severity of AA.

Background/Aim: Mesenchymal stem cells (MSCs) are gaining rising interest in gynecology and obstetrics. MSCs immunomodulatory properties are suitable enough to reduce perinatal morbidity caused by inflammation in premature neonates. The aim of this study was to evaluate and compare the ability to inhibit allo-activated lymphocytes proliferation by MSCs derived from different sources: amniotic membrane (AM), umbilical cord (UC) and adipose tissue (AT). Methods: MSCs were isolated from AM (n = 7) and UC (n = 6) and AT (n = 6) of healthy women. Cells were characterized by flow cytometry and differentiation assay. To evaluate the potential of fetal and adult MSCs to diminish immunological response, mixed lymphocytes reaction (MLR) was performed. Results: Amnion and UC-derived cells displayed typical MSCs characteristics. Addition of MSCs to MLR significantly inhibited the proliferation of stimulated lymphocytes. The effect was observed regardless of the MSCs type used (p < 0.01 in all groups). Comparative analysis revealed no significant differences in this action between tested MSCs types. Additionally, no type of MSCs significantly stimulated allogeneic lymphocytes. Conclusion: The results prove the immunosuppressive capacities of fetal-derived MSCs in vitro. In the future, they may be potentially used to treat premature newborn as well as in immunomodulation in post-transplant therapy.

IntroductionMortality, whether in or out of hospital, increases with age. However, studies evaluating in-hospital mortality in large populations did not distinguish between surgical and non-surgical causes of death, either in young or in elderly patients. The aim of the study was to assess in-hospital non-surgical mortality in a large group of patients, with a special focus on the elderly.Material and methodsData from the database of the Polish National Health Fund (NHF) regarding hospitalizations of adult (≥ 18 years) patients not related to surgical procedures in the years 2009–2013 were used to assess in-hospital mortality.Results15,345,025 hospitalizations were assessed. The mean in-hospital non-surgery-related mortality rate was 3.96 ±0.17%, and increased from 3.79% to 4.2% between 2009 and 2013. The mean odds ratio for in-hospital death increased with the age of patients, reaching a 229-fold higher rate in the ≥ 95 years age group as compared to the 18–24 age group. The highest mean mortality was associated with respiratory diseases (6.91 ±0.20%), followed by heart and vascular diseases, nervous system diseases, as well as combined gastrointestinal tract, liver, biliary tract, pancreas and spleen diseases (5.65 ±0.27%, 5.46 ±0.05% and 4.01 ±0.13%, respectively).ConclusionsThe in-hospital non-surgery-related mortality rate was approximately 4%. It significantly increased with age and, regardless of age, was highest in patients suffering from respiratory diseases.
