CD4FOXP3Exon2 regulatory T cell frequency predicts breast cancer prognosis and survival.

CD4FOXP3 regulatory T cells (T) suppress immune responses to tumors, and their accumulation in the tumor microenvironment (TME) correlates with poor clinical outcome in several cancers, including breast cancer (BC). However, the properties of intratumoral T remain largely unknown. Here, we found that a functionally distinct subpopulation of T, expressing the FOXP3 Exon2 splicing variants, is prominent in patients with hormone receptor-positive BC with poor prognosis.

Iron deficiency anemia in pregnancy and the postpartum: a practical approach by the Italian GOAL Working Group.

Background: Iron deficiency and iron deficiency anemia represent global health issues, particularly during pregnancy and the postpartum. The present paper aims to summarize the appropriate management of these conditions in order to try to improve how clinicians perceive, diagnose and treat iron deficiency and iron deficiency anemia.

Methods: An expert panel of Italian obstetricians of Lazio region was convened to evaluate the available literature on iron deficiency and iron deficiency anemia during pregnancy and the post-partum in order to try to define a flow chart on the appropriate management of such conditions; aspects related to the patient blood management have also been investigated.

Mercury speciation in environmental samples associated with artisanal small-scale gold mines using a novel solid-phase extraction approach to sample collection and preservation.

In artisanal small-scale gold mines (ASGM), mercury (Hg) is known to pollute nearby river waters and sediments where it can be methylated to the highly bioavailable methylmercury (MeHg). The assessment of Hg speciation in water samples has been challenging for many years, with recommended procedures often not adequately allowing for analysis of samples in a suitable timeframe. Using a novel solid-phase extraction (SPE) method for sampling and preservation of Hg species, representative speciation data can be safely and easily collected and retained for up to 4-weeks (MeHg = 115 ± 8% refrigerated and 109 ± 13% unrefrigerated storage; Hg  = 100 ± 14% refrigerated and 94 ± 12% unrefrigerated storage).

Field method for preservation of total mercury in waters, including those associated with artisanal scale gold mining.

Analysis of mercury (Hg) in natural water samples has routinely been impractical in many environments, for example, artisanal and small-scale gold mines (ASGM), where difficult conditions make monitoring of harmful elements and chemicals used in the processes highly challenging. Current sampling methods require the use of hazardous or expensive materials, and so difficulties in sample collection and transport are elevated. To solve this problem, a solid-phase extraction-based method was developed for the sampling and preservation of dissolved Hg in natural water samples, particularly those found around ASGM sites.

Safety and effects of calcifediol 0.266 milligrams soft capsules monthly and cholecalciferol 25000 international units monthly in osteoporotic women undergoing therapy with alendronate: a cross-sectional study.

Background: The role of vitamin D in human physiology is a topic of great interest for the scientific community in the last decades. The common target for all clinicians is to improve its status in order to prevent several pathological conditions.

Methods: The aim of our study was to evaluate the safety and the efficacy of both calcifediol and cholecalciferol in combination with alendronate in osteoporotic women.
