Emerging Contaminants is a leading platform for research addressing the potential ecological and human health risks associated with environmental contamination from emerging contaminants.

The largest nationwide Polish study on migraine and sleep, involving 5,311 adults, found a strong association between migraine and poorer sleep quality. Nearly two-thirds (64.1%) of people with migraine reported poor sleep, compared with 38.7% of participants without headaches. People with migraine experienced problems across all assessed aspects of sleep, including falling asleep, sleep duration and efficiency, nighttime awakenings, and daytime functioning.

Poorer sleep was also associated with a greater migraine burden, including more frequent attacks, greater disability, higher stress and anxiety, and lower quality of life. The study additionally found that people with migraine were more likely to have a later chronotype, although the relationship between chronotype and migraine severity was weak.

The findings support a bidirectional relationship between migraine and sleep disturbances and suggest that sleep assessment should be routinely included in migraine care. However, because the study was cross-sectional and relied on self-reported data, it cannot establish causality. Further longitudinal studies using objective sleep measurements are needed.

The 2026 ESC Guidelines on Cardiac Rehabilitation redefine cardiac rehabilitation as an integral part of cardiovascular treatment and long-term secondary prevention, rather than simply a period of exercise after a heart attack or procedure. Rehabilitation can begin during hospitalization and continue in specialized centers, at home, through telerehabilitation, or in hybrid models.

The guidelines emphasize a comprehensive, multidisciplinary approach combining individualized physical training with risk factor management, medication optimization, nutritional counseling, patient education, smoking cessation support and psychosocial care. Programs should be tailored to each patient, including older people and those with frailty or multiple chronic conditions.

Cardiac rehabilitation can improve physical functioning, quality of life and psychological well-being while reducing rehospitalizations and, in selected patient groups, the risk of cardiovascular events. The recommendations now cover a broad range of cardiovascular conditions, including coronary syndromes, heart failure, valvular disease, atrial fibrillation and cardiomyopathies.

A major focus of the guidelines is also improving access to rehabilitation. Home-based programs and telerehabilitation may help reach patients who live far from rehabilitation centers or face other barriers to participation.

The guidelines were published in the European Heart Journal in August 2026. Associate Professor Michał Czapla from Wroclaw Medical University is one of their co-authors.

A large three-year newborn screening program found that more than half of babies with congenital CMV would have been missed by standard targeted screening because many appeared healthy at birth. The findings suggest that routine saliva-based screening could help identify affected infants earlier, allowing for closer monitoring and, when needed, timely treatment, while pooled testing may make large-scale screening more practical.
