A regional comparison of children's blood cadmium, lead, and mercury in rural, urban and industrial areas of six European countries, and China, Ecuador, and Morocco.

Objectives: The authors aimed to evaluate whether blood cadmium (B-Cd), lead (B-Pb) and mercury (B-Hg) in children differ regionally in 9 countries, and to identify factors correlating with exposure.

Material And Methods: The authors performed a cross-sectional study of children aged 7-14 years, living in 2007-2008 in urban, rural, or potentially polluted ("hot spot") areas (ca. 50 children from each area, in total 1363 children) in 6 European and 3 non-European countries.

The concurrent impact of mild cognitive impairment and frailty syndrome in heart failure.

Pathological processes associated with ageing increase the risk of cognitive deficits and dementia. Frailty syndrome, also known as weakness or reserve depletion syndrome, may significantly accelerate these pathological processes in the elderly population. Frailty syndrome is characterized by decreased physiological function and neuropsychiatric symptoms, including cognitive decline and depressive states.

Anxiety and Psychological Flexibility in Women After Childbirth in the Rooming-in Unit during the COVID-19 Pandemic.

Introduction: The coronavirus disease 2019 (COVID-19) pandemic has intensified perinatal anxiety disorders. Psychological flexibility (PF), considered a specific mental toughness, has not been examined with regard to its relationship with anxiety in women after childbirth. We aimed to compare levels of anxiety, PF, and pain in women depending on the mode of birth, parity, and the magnitude of risk of developing an anxiety disorder.

How to Improve the Care of Women after Childbirth in the Rooming-in Unit: A Prospective Observational Study.

Rooming-in is the WHO-recommended care system for mothers in the puerperium and their babies. This system allows the newborn to stay with the mother in the same room, 24 h a day. We aimed to investigate the need to entrust a newborn (NEN) in the care of maternity rooming-in staff during the COVID-19 pandemic, and its relationship to pain, anxiety, and blood loss after delivery.

Association Between Serum Selenium Concentration and OPG/RANKL/RANK Axis in Patients with Arterial Hypertension.

The aim of the study was to determine the relationship between the serum selenium concentration (Se-S) and the blood concentrations of osteoprotegerin (OPG), receptor activator of nuclear factor kappa-Β ligand (RANKL) and the OPG/RANKL ratio in patients with arterial hypertension. The study group comprised 138 patients with arterial hypertension (age: 56.04 ± 11.
